Part I
Items 1. and 2. Business and Properties
General
In 1995, DTE Energy incorporated in the State of Michigan. DTE Energy's utility operations consist primarily of DTE Electric and DTE Gas. DTE Energy also
has two other segments that are engaged in a variety of energy-related businesses.
DTE Electric is a Michigan corporation organized in 1903 and is an indirect wholly-owned subsidiary of DTE Energy. DTE Electric is a public utility engaged in
the generation, purchase, distribution, and sale of electricity to approximately 2.3 million customers in southeastern Michigan.
DTE Gas is a Michigan corporation organized in 1898 and is an indirect wholly-owned subsidiary of DTE Energy. DTE Gas is a public utility engaged in the
purchase, storage, transportation, distribution, and sale of natural gas to approximately 1.3 million customers throughout Michigan and the sale of storage and
transportation capacity.
DTE Energy's other businesses include 1) DTE Vantage which is primarily involved in renewable natural gas projects and providing custom energy solutions to
industrial, commercial, and institutional customers, and 2) energy marketing and trading operations.
DTE Electric and DTE Gas are regulated by the MPSC. Certain activities of DTE Electric and DTE Gas, as well as various other aspects of businesses under DTE
Energy, are regulated by the FERC. In addition, the Registrants are regulated by other federal and state regulatory agencies including the NRC, the EPA, EGLE, and for
DTE Energy, the CFTC and CARB.
The Registrants' annual reports on Form 10-K, quarterly reports on Form 10-Q, current reports on Form 8-K, proxy statements, and all amendments to such reports
are available free of charge through the Investor Relations SEC Filings page of DTE Energy's website: www.dteenergy.com, as soon as reasonably practicable after they
are filed with or furnished to the SEC.
The DTE Energy Code of Ethics and Standards of Behavior, Board of Directors’ Mission and Guidelines, Board Committee Charters, and Categorical Standards
for Director Independence are also posted on the DTE Energy website. The information on DTE Energy’s website is not part of this report or any other report that DTE
Energy files with, or furnishes to, the SEC.
Additionally, the public may read and copy any materials the Registrants file electronically with the SEC at www.sec.gov.

regional development and economic growth.
Refer to Management’s Discussion and Analysis in Item 7 of this Report for an in-depth analysis of each segment’s financial results. A description of each business
unit follows.
ELECTRIC SEGMENT
Description
DTE Energy's Electric segment consists principally of DTE Electric, an electric utility engaged in the generation, purchase, distribution, and sale of electricity to
approximately 2.3 million customers in southeastern Michigan. DTE Electric is regulated by numerous federal and state governmental agencies, including, but not
limited to, the MPSC, the FERC, the NRC, the EPA, and EGLE. Electricity is primarily generated by two coal-fired plants, a combined cycle natural gas plant, a
hydroelectric pumped storage plant, a nuclear plant, wind and solar assets, and is supplemented with purchased power. The electricity is sold, or distributed through the
retail access program, to three major classes of customers: residential, commercial, and industrial, throughout southeastern Michigan.
Weather, economic factors, competition, energy waste reduction initiatives, and electricity prices affect sales levels to customers. DTE Electric's peak load and
highest total system sales generally occur during the third quarter of the year, driven by air conditioning and other cooling-related demands. DTE Electric's operations
are not dependent upon a limited number of customers, and the loss of any one or a few customers would not have a material adverse effect on the results of DTE
Electric.
The Electric segment also includes non-utility operations relating to renewable energy projects at DTE Sustainable Generation, which were acquired to support
DTE Energy's renewable energy goals.
For a summary of Electric segment operating revenues by service, see Note 4 to the Consolidated Financial Statements, "Revenue."
Fuel Supply and Purchased Power
DTE Electric's power is generated primarily from a variety of fuels and is supplemented with renewable generation and purchased power. DTE Electric expects to
have an adequate supply of power to meet its obligation to serve customers. DTE Electric's generating capability is largely dependent upon the availability of coal and
natural gas.
Coal is purchased from various sources in different geographic areas under agreements that vary in both pricing and terms. DTE Electric expects to obtain the
majority of its coal requirements through long-term contracts, with the balance to be obtained through short-term agreements and spot purchases. DTE Electric has long-
term and short-term contracts for the purchase of approximately 7.5 million tons of low-sulfur western coal and approximately 1.2 million tons of Appalachian coal to
be delivered from 2025 to 2026. All of these contracts have pricing schedules. DTE Electric has 100% of its expected coal requirements under contract for 2025. DTE
Electric leases a fleet of rail cars and has the expected western and eastern coal rail requirements under multi-year contracts. DTE Electric's 2025 rail transportation is
covered under long-term agreements. DTE Electric expects to cover all of its 2025 vessel transportation requirements for delivery of purchased coal to electric
generating facilities through existing agreements.
7

Table of Contents
DTE Electric's natural gas supply requirements are expected to be met through a combination of short and long-term agreements, agreements with local
distribution companies, and spot market purchases. Natural gas purchase requirements for 2025 are expected to be approximately 80 Bcf. DTE Electric has contracts for
firm gas transportation and storage capacity to ensure reliable and flexible gas supply to its power plants. Given the geographic diversity of supply, DTE Electric
believes it can meet its expected generation requirements.
DTE Electric participates in the energy market through MISO. DTE Electric offers its generation in the market on a day-ahead and real-time basis and bids for
power in the market to serve its load. DTE Electric is a net purchaser of power that supplements its generation capability to meet customer demand during peak cycles
or during major plant outages.
Properties
DTE Electric owns generating facilities that are located in the State of Michigan. Substantially all of DTE Electric's property is subject to the lien of a mortgage.

There are numerous interconnections that allow the interchange of electricity between DTE Electric and electricity providers external to the DTE Electric service
area. These interconnections are generally owned and operated by ITC Transmission, an unrelated company, and connect to neighboring energy companies.
Regulation
DTE Electric is subject to the regulatory jurisdiction of various agencies, including, but not limited to, the MPSC, the FERC, and the NRC. The MPSC issues
orders pertaining to rates, recovery of certain costs, including the costs of generating facilities and regulatory assets, conditions of service, accounting, and operating-
related matters. DTE Electric's MPSC-approved rates charged to customers have historically been designed to allow for the recovery of costs, plus an authorized rate of
return on investments. The FERC regulates DTE Electric with respect to financing authorization, wholesale electric market activities, certain affiliate transactions, the
acquisition and disposition of certain generation and other facilities, and, in conjunction with the NERC, compliance with mandatory reliability standards. The NRC has
regulatory jurisdiction over all phases of the operation, construction, licensing, and decommissioning of DTE Electric's nuclear plant operations. DTE Electric is subject
to the requirements of other regulatory agencies with respect to safety, the environment, and health.
See Notes 7, 8, 11, 17, and 18 to the Consolidated Financial Statements, "Asset Retirement Obligations," "Regulatory Matters," "Fair Value," "Commitments and
Contingencies," and "Nuclear Operations."
Energy Assistance Programs
Energy assistance programs, funded by the federal government and the State of Michigan, remain critical to DTE Electric’s ability to control its uncollectible
accounts receivable and collections expenses. DTE Electric’s uncollectible accounts receivable expense is directly affected by the level of government-funded assistance
that qualifying customers receive. DTE Electric works continuously with the State of Michigan and others to determine whether the share of funding allocated to
customers is representative of the number of low-income individuals in the service territory. DTE Electric also partners with federal, state, and local officials to attempt
to increase the share of low-income funding allocated to customers.
Strategy and Competition
DTE Electric's electrical generation operations seek to provide the energy needs of customers in a cost-effective manner and support DTE Energy's goal to reduce
carbon emissions by 65% in 2028, 85% in 2032, and 90% by 2040 from 2005 carbon emissions levels, as well as net zero emissions by 2050. With potential capacity
constraints in the MISO region, there will be increased dependency on DTE Electric's generation to provide reliable service and price stability for customers.
Additionally, as a result of legislation passed by the state of Michigan in the fourth quarter 2023, DTE Electric will be required to meet a 100% clean energy
portfolio standard by 2040. Clean energy sources include renewables, nuclear, and natural gas-fired plants, provided such plants utilize a carbon capture and storage
system that is at least 90% effective to offset carbon emissions. The legislation also requires 50% of an electric utility's energy to be generated from renewable sources
by 2030 and 60% by 2035. DTE Electric is currently assessing the impacts of this legislation and will include updates in its next Integrated Resource Plan to comply
with the new requirements.

To maintain reliability and meet carbon reduction goals in the near-term, DTE Electric will continue its energy waste reduction initiatives and transition away from
coal-fired plants to renewable energy and other sources, including leveraging existing infrastructure at the Belle River power plant through a coal to natural gas
conversion. To achieve long-term carbon reduction goals, DTE Electric plans to end the use of coal-fired power plants in 2032 and plans significant investments in solar,
wind, and battery storage. DTE Electric expects this transition to renewables and natural gas to reduce future operating and fuel costs. DTE Electric will also continue to
monitor the advancement of emerging technologies such as long-duration storage, modular nuclear reactors, hydrogen, and carbon capture and sequestration, and how
these technologies may support clean, reliable generation and customer affordability.
DTE Electric's distribution operations focus is on distributing energy in a safe, cost-effective, and reliable manner to customers. An increasing intensity of
windstorms and other weather events, coupled with increasing electric vehicle adoption and potential for data centers, will drive a continued need for substantial grid
investment over the long-term. DTE Electric is hardening and upgrading its infrastructure and has plans to build substations to provide additional capacity as customers
shift to more electrification, including electric vehicles. DTE Electric seeks to increase operational efficiencies to maintain rate affordability and increase reliability and
customer satisfaction through accelerated tree trimming, pole maintenance, enhanced grid automation to reduce outage duration, and increased underground distribution.
To enhance customer affordability, DTE Electric is also working to optimize opportunities from the Inflation Reduction Act to generate production tax credits for
wind and solar production and existing nuclear generation, as well as investment tax credits for solar and energy storage. DTE Electric expects these tax credits to
reduce the cost of owning assets that support its clean energy transition, thereby reducing customer rate impacts from any future cost recoveries.
The electric retail access program in Michigan gives electric customers the option of retail access to alternative electric suppliers, subject to limits. Energy
legislation enacted by the State of Michigan has placed a 10% cap on total retail access. This cap mitigates some of the unfavorable effects of electric retail access on
DTE Electric's financial performance and full-service customer rates. Customers with retail access to alternative electric suppliers consist primarily of industrial and
commercial customers and represented approximately 10%, of retail sales in 2024, 2023 and 2022. DTE Electric expects that customers with retail access to alternative
electric suppliers will remain at approximately 10% of retail sales in 2025 and future years.
Competition in the regulated electric distribution business is primarily from the on-site generation of industrial customers and from distributed generation
applications by industrial and commercial customers. DTE Electric does not expect significant competition for distribution to any group of customers in the near term.
Revenues from year to year will vary due to weather conditions, economic factors, regulatory events, and other risk factors as discussed in the "Risk Factors" in
Item 1A. of this Report.
GAS SEGMENT
Description
DTE Energy's Gas segment consists principally of DTE Gas, a natural gas utility engaged in the purchase, storage, transportation, distribution, and sale of natural
gas to approximately 1.3 million residential, commercial, and industrial customers throughout Michigan, and the sale of storage and transportation capacity.
DTE Gas' natural gas sales, end-user transportation, and intermediate transportation volumes, revenues, and Net Income are impacted by weather. Given the
seasonal nature of the business, revenues and earnings are concentrated in the first and fourth quarters of the calendar year. By the end of the first quarter, the heating
season is largely over, and DTE Gas typically realizes substantially reduced revenues and earnings in the second quarter, and losses in the third quarter. The impacts of
changes in annual average customer usage may be minimized by Revenue Decoupling Mechanisms authorized by the MPSC.
DTE Gas operations are not dependent upon a limited number of customers, and the loss of any one or a few customers would not have a material adverse effect
on the results of DTE Gas.
For a summary of Gas segment operating revenues by service, see Note 4 to the Consolidated Financial Statements, "Revenue."

Table of Contents
Natural Gas Supply
DTE Gas' gas distribution system has a planned maximum daily send-out capacity of 2.5 Bcf, with approximately 65% of the volume coming from underground
storage for 2024. Peak-use requirements are met through utilization of storage facilities, pipeline transportation capacity, and purchased gas supplies. Because of the
geographic diversity of supply and its pipeline transportation and storage capacity, DTE Gas is able to reliably meet supply requirements. DTE Gas believes natural gas
supply and pipeline capacity will be sufficiently available to meet market demands in the foreseeable future.
DTE Gas purchases natural gas supplies in the open market by contracting with producers and marketers and maintains a diversified portfolio of natural gas supply
contracts. Supplier, producing region, quantity, and available transportation diversify DTE Gas' natural gas supply base. Natural gas supply is obtained from various
sources in different geographic areas (Appalachian, Gulf Coast, Mid-Continent, Canada, and Michigan) under agreements that vary in both pricing and terms. Gas
supply pricing is generally tied to the New York Mercantile Exchange and published price indices to approximate current market prices combined with MPSC-approved
fixed price supplies with varying terms and volumes through 2027.
DTE Gas is directly connected to interstate pipelines, providing access to most of the major natural gas supply producing regions in the Appalachian, Gulf Coast,
Mid-Continent, and Canadian regions. The primary long-term transportation supply contracts at December 31, 2024 are listed below.

Properties
DTE Gas owns distribution, storage, and transportation properties that are located in the State of Michigan. The distribution system includes approximately
20,500 miles of distribution mains, approximately 1,238,000 service pipelines, and approximately 1,352,000 active meters. DTE Gas also owns approximately 2,000
miles of transmission pipelines that deliver natural gas to the distribution districts and interconnect DTE Gas storage fields with the sources of supply and the market
areas.
DTE Gas owns storage properties relating to four underground natural gas storage fields with an aggregate working gas storage capacity of approximately 139
Bcf. These facilities are important in providing reliable and cost-effective service to DTE Gas customers. In addition, DTE Gas sells storage services to third parties.
Most of DTE Gas' distribution and transportation property is located on property owned by others and used by DTE Gas through easements, permits, or licenses.
Substantially all of DTE Gas' property is subject to the lien of a mortgage.
Regulation
DTE Gas is subject to the regulatory jurisdiction of the MPSC, which issues orders pertaining to rates, recovery of certain costs, including the costs of regulatory
assets, conditions of service, accounting, and operating-related matters. DTE Gas' MPSC-approved rates charged to customers have historically been designed to allow
for the recovery of costs, plus an authorized rate of return on investments. DTE Gas operates natural gas storage and transportation facilities in Michigan as intrastate
facilities regulated by the MPSC and provides intrastate storage and transportation services pursuant to a MPSC-approved tariff.
DTE Gas also provides interstate storage and transportation services in accordance with an Operating Statement on file with the FERC. The FERC's jurisdiction is
limited and extends to the rates, non-discriminatory requirements, and the terms and conditions applicable to storage and transportation provided by DTE Gas in
interstate markets. FERC granted DTE Gas authority to provide storage and related services in interstate commerce at market-based rates. DTE Gas provides
transportation services in interstate commerce at cost-based rates approved by the MPSC and filed with the FERC.
DTE Gas is subject to the requirements of other regulatory agencies with respect to safety, the environment, and health.

Energy Assistance Programs
Energy assistance programs, funded by the federal government and the State of Michigan, remain critical to DTE Gas' ability to control its uncollectible accounts
receivable and collections expenses. DTE Gas' uncollectible accounts receivable expense is directly affected by the level of government-funded assistance its qualifying
customers receive. DTE Gas works continuously with the State of Michigan and others to determine whether the share of funding allocated to customers is
representative of the number of low-income individuals in the service territory. DTE Gas also partners with federal, state, and local officials to attempt to increase the
share of low-income funding allocated to customers.
Strategy and Competition
DTE Gas' strategy is to ensure the safe, reliable, and cost-effective delivery of natural gas service within its franchised markets in Michigan. In addition, DTE Gas
is promoting the extension of its distribution system to underserved markets and the increased use of natural gas furnaces, water heaters, and appliances within its
current customer base. DTE Gas continues to focus on the reduction of operating costs and the delivery of energy waste reduction products and services to its customers,
making natural gas service the preferred fuel and even more affordable for its customers.
Competition in the gas business primarily involves other natural gas transportation providers, as well as providers of alternative fuels and energy sources. The
primary focus of competition for end-user transportation is cost and reliability. Some large commercial and industrial customers have the ability to switch to alternative
fuel sources such as coal, electricity, oil, and steam. If these customers were to choose an alternative fuel source, they would not have a need for DTE Gas' end-user
transportation service. DTE Gas competes against alternative fuel sources by providing competitive pricing and reliable service, supported by its storage capacity.
Having an extensive transportation pipeline system has enabled marketing of DTE Gas' storage and transportation services to gas producers, marketers,
distribution companies, end-user customers, and other pipeline companies. The business operates in a central geographic location with connections to major Midwestern
interstate pipelines that extend throughout the Midwest, eastern United States, and eastern Canada.
DTE Gas' storage capacity is used to store natural gas for delivery to its customers and is also sold to third parties under a variety of arrangements. Prices are
influenced primarily by market conditions, weather, and natural gas pricing.
DTE Energy plans to reduce the carbon emissions from its gas utility operations by 65% by 2030 and 80% by 2040, and is committed to a goal of net zero carbon
emissions by 2050 from internal gas operations and gas suppliers. To achieve net zero, DTE Gas is working to source gas with lower methane intensity, reduce
emissions through its main renewal and pipeline integrity programs, and if necessary, use carbon offsets to address any remaining emissions. DTE Energy also aims to
help DTE Gas customers reduce their emissions by approximately 35% by 2040 by increasing energy efficiency, pursuing advanced technologies such as hydrogen and
carbon capture and sequestration, and through the CleanVision Natural Gas Balance program which provides customers the option to use carbon offsets and renewable
natural gas.

ENERGY TRADING SEGMENT
Description
The Energy Trading segment focuses on physical and financial power, natural gas and environmental marketing and trading, structured transactions, enhancement
of returns from its asset portfolio, and optimization of contracted natural gas pipeline transportation and storage positions. Energy Trading also provides natural gas,
power, environmental and related services which may include the management of associated storage and transportation contracts on the customers’ behalf and the
supply or purchase of environmental attributes to various customers. Energy Trading's customer base is predominantly utilities, local natural gas distribution companies,
pipelines, producers and generators, and other marketing and trading companies. Energy Trading also provides commodity risk management services to the other
businesses within DTE Energy.
Energy Trading enters into derivative financial instruments as part of its marketing and hedging activities. These financial instruments are generally accounted for
under the MTM method, which results in the recognition in earnings of unrealized gains and losses from changes in the fair value of the derivatives. Energy Trading
utilizes forwards, futures, swaps, and option contracts to mitigate risk associated with marketing and trading activity, as well as for proprietary trading within defined
risk guidelines.
Significant portions of the Energy Trading portfolio are economically hedged. Most financial instruments, physical power and natural gas contracts, and certain
environmental contracts are deemed derivatives; whereas, natural gas and environmental inventory, contracts for pipeline transportation, storage assets, and some
environmental contracts are not derivatives. As a result, this segment will experience earnings volatility as derivatives are marked-to-market without revaluing the
underlying non-derivative contracts and assets. The business’ strategy is to economically manage the price risk of these underlying non-derivative contracts and assets
with futures, forwards, swaps, and options. This results in gains and losses that are recognized in different interim and annual accounting periods.
Regulation
Energy Trading has market-based rate authority from the FERC to sell power and blanket authority from the FERC to sell natural gas at market prices. Energy
Trading is subject to FERC reporting requirements and market behavior rules. Energy Trading is also subject to the applicable laws, rules, and regulations related to the
CFTC, U.S. Department of Homeland Security, and DOE. In addition, Energy Trading is subject to applicable laws, rules, and regulations in Canada.

Item 1A. Risk Factors
There are various risks associated with the operations of the Registrants' utility businesses and DTE Energy's non-utility businesses. To provide a framework to
understand the operating environment of the Registrants, below is a brief explanation of the more significant risks associated with their businesses. Although the
Registrants have tried to identify and discuss key risk factors, others could emerge in the future. Each of the following risks could affect performance.
Regulatory, Legislative, and Legal Risks
The Registrants are subject to rate regulation. Electric and gas rates for the utilities are set by the MPSC and the FERC and cannot be changed without regulatory
authorization. The Registrants may be negatively impacted by new regulations or interpretations by the MPSC, the FERC, or other regulatory bodies. The Registrants'
ability to recover costs may be impacted by the time lag between the incurring of costs and the recovery of the costs in customers' rates. Regulators also may decide to
disallow recovery of certain costs in customers' rates if they determine that those costs do not meet the standards for recovery under current governing laws and
regulations. Regulators may also disagree with the Registrants' rate calculations under the various mechanisms that are intended to mitigate the risk to their utilities
related to certain aspects of the business. If the Registrants cannot agree with regulators on an appropriate reconciliation of those mechanisms, it may impact the
Registrants' ability to recover certain costs through customer rates. Regulators may also decide to eliminate these mechanisms in future rate cases, which may make it
more difficult for the Registrants to recover their costs in the rates charged to customers. The Registrants cannot predict what rates the MPSC will authorize in future
rate cases, and unfavorable rate relief could impact our plans for significant capital investment. New legislation, regulations, or interpretations could change how the
business operates, impact the Registrants' ability to recover costs through rates or the timing of such recovery, or require the Registrants to incur additional expenses.
Changes to Michigan's electric retail access program could negatively impact the Registrants' financial performance. The State of Michigan currently experiences
a hybrid market, where the MPSC continues to regulate electric rates for DTE Electric customers, while alternative electric suppliers charge market-based rates. MPSC
rate orders, and energy legislation enacted by the State of Michigan, have placed a 10% cap on the total potential retail access migration. However, even with the
legislated 10% cap on participation, there continues to be legislative and financial risk associated with the electric retail access program. Electric retail access migration
is sensitive to market price and full service electric price changes. The Registrants are required under current regulation to provide full service to retail access customers
that choose to return, potentially resulting in the need for additional generating capacity.
Environmental laws and liability may be costly. The Registrants are subject to, and affected by, numerous environmental regulations. These regulations govern air
emissions, water quality, wastewater discharge, and disposal of solid and hazardous waste. Compliance with these regulations can significantly increase capital
spending, operating expenses, and plant down times, and can negatively affect the affordability of the rates charged to customers.
Uncertainty around future environmental regulations creates difficulty planning long-term capital projects in the Registrants' generation fleet and for DTE Energy's
gas distribution businesses. These laws and regulations require the Registrants to seek a variety of environmental licenses, permits, inspections, and other regulatory
approvals. The Registrants could be required to install expensive pollution control measures or limit or cease activities, including the retirement of certain generating
plants, based on these regulations. Additionally, the Registrants may become a responsible party for environmental cleanup at sites identified by a regulatory body. The
Registrants cannot predict with certainty the amount and timing of future expenditures related to environmental matters because of the difficulty of estimating cleanup
costs. There is also uncertainty in quantifying liabilities under environmental laws that impose joint and several liability on potentially responsible parties.

Table of Contents
The Registrants may also incur liabilities as a result of potential future requirements to address climate change issues. Proposals for voluntary initiatives and
mandatory controls are being discussed in Michigan, the United States, and worldwide to reduce GHGs such as carbon dioxide, a by-product of burning fossil fuels. If
increased regulations of GHG emissions are implemented, or if existing deadlines for these regulations are accelerated, the operations of DTE Electric's fossil-fueled
generation assets may be significantly impacted. Increased environmental regulation may also result in greater energy efficiency requirements and decreased demand at
both the electric and gas utilities. Since there can be no assurances that environmental costs may be recovered through the regulatory process, the Registrants' financial
performance may be negatively impacted as a result of environmental matters.
Any perceived or alleged failure by the Registrants to comply with environmental regulations could lead to fines or penalties imposed by regulatory bodies or
could result in adverse public statements and reputational damage affecting the Registrants. Adverse statements, whether or not driven by political or public sentiment,
may also result in investigations by regulators, legislators and law enforcement officials or in legal claims.
The Clean Energy Standard, Renewable Portfolio Standard and energy waste reduction may affect the Registrants' business and federal and state fuel standards
may affect DTE Energy's non-utility investments. The Registrants are subject to existing Michigan, and potential future, federal legislation and regulation requiring them
to secure sources of clean and renewable energy. The Registrants have complied with the existing federal and state legislation, but do not know what requirements may
be added by federal or state legislation in the future. In addition, the Registrants expect to comply with new Michigan legislation increasing the percentage of power
required to be provided by clean energy resources and renewable energy sources. The Registrants cannot predict the financial impact or costs associated with complying
with potential future legislation and regulations. Compliance with these requirements can significantly increase capital expenditures and operating expenses and can
negatively affect the affordability of the rates charged to customers.
In addition, the Registrants are also required by Michigan legislation to implement energy waste reduction measures and provide energy waste reduction customer
awareness and education programs. These requirements necessitate expenditures, and implementation of these programs creates the risk of reducing the Registrants'
revenues as customers decrease their energy usage. The Registrants cannot predict how these programs will impact their business and future operating results.
DTE Energy's non-utility renewable natural gas investments are also dependent on the federal Renewable Fuel Standard and California's Low Carbon Fuel
Standard. Changes to these standards may affect DTE Energy's business and result in lower earnings.
DTE Energy's ability to utilize tax credits may be limited. To promote U.S. climate initiatives, the Internal Revenue Code provides tax credits as an incentive for
taxpayers to produce energy from alternative sources. The Registrants have generated tax credits from renewable energy generation and DTE Energy has generated tax
credits from renewable gas recovery, reduced emission fuel, and gas production operations. If the Registrants' tax credits were disallowed in whole or in part as a result
of an IRS audit or changes in tax law, there could be additional tax liabilities owed for previously recognized tax credits that could significantly impact the Registrants'
earnings and cash flows.
Operational Risks
The Registrants' electric distribution system and DTE Energy's gas distribution system are subject to risks from their operation, which could reduce revenues,
increase expenses, and have a material adverse effect on their business, financial position, and results of operations. The Registrants' electric distribution and DTE
Energy’s gas distribution systems are subject to many operational risks. These operational systems and infrastructure have been in service for many years. Equipment,
even when maintained in accordance with good utility practices, is subject to operational failure, including events that are beyond the Registrants' control, and could
require significant operation and maintenance expense or capital expenditures to operate efficiently. Because the Registrants’ distribution systems are interconnected
with those of third parties, the operation of the Registrants’ systems could be adversely affected by unexpected or uncontrollable events occurring on the systems of such
third parties.
19

Table of Contents
Construction and capital improvements to the Registrants' power facilities and DTE Energy's distribution systems subject them to risk. The Registrants are
managing ongoing, and planning future, significant construction and capital improvement projects at the Registrants' multiple power generation and distribution
facilities and at DTE Energy's gas distribution system. Many factors that could cause delays or increased prices for these complex projects are beyond the Registrants'
control, including the cost of materials and labor, subcontractor performance, timing and issuance of necessary permits or approvals (including required certificates from
regulatory agencies), construction disputes, impediments to acquiring rights-of-way or land rights on a timely basis and on acceptable terms, cost overruns, and weather
conditions. Failure to complete these projects on schedule and on budget for any reason could adversely affect the Registrants' financial performance, operations, or
expected investment returns at the affected facilities, businesses and development projects.
Operation of a nuclear facility subjects the Registrants to risk. Ownership of an operating nuclear generating plant subjects the Registrants to significant additional
risks. These risks include, among others, plant security, environmental regulation and remediation, changes in federal nuclear regulation, increased capital expenditures
to meet industry requirements, and operational factors that can significantly impact the performance and cost of operating a nuclear facility compared to other
generation options. Insurance maintained by the Registrants for various nuclear-related risks may not be sufficient to cover the Registrants' costs in the event of an
accident or business interruption at the nuclear generating plant, which may affect the Registrants' financial performance. In addition, the Registrants' nuclear
decommissioning trust fund, to finance the decommissioning of the nuclear generating plant, may not be sufficient to fund the cost of decommissioning. A decline in
market value of assets held in decommissioning trust funds due to poor investment performance or other factors may increase the funding requirements for these
obligations. Any increase in funding requirements may have a material impact on the Registrants’ liquidity, financial position, or results of operations.
The supply and/or price of energy commodities and/or related services may impact the Registrants' financial results. The Registrants are dependent on coal for
much of their electrical generating capacity as well as uranium for their nuclear operations. DTE Energy's access to natural gas supplies is critical to ensure reliability of
service for utility gas customers. DTE Energy's non-utility businesses are also dependent upon supplies and prices of energy commodities and services. Price
fluctuations and changes in transportation costs, driven by inflation or other factors, as well as fuel supply disruptions, could have a negative impact on the amounts
DTE Electric charges utility customers for electricity and DTE Gas charges utility customers for gas, and on the profitability of DTE Energy's non-utility businesses.
The Registrants' hedging strategies and regulatory recovery mechanisms may be insufficient to mitigate the negative fluctuations in commodity supply prices at their
utility or DTE Energy's non-utility businesses, and the Registrants' financial performance may therefore be negatively impacted by price fluctuations.
The price of energy also impacts the market for DTE Energy's non-utility businesses, particularly those that compete with utilities and alternative electric
suppliers. The price of environmental attributes generated by DTE Energy's renewable natural gas investments, including those related to the federal Renewable Fuel
Standard and California's Low Carbon Fuel Standard, may also impact the market and financial results for DTE Energy's non-utility businesses.
The supply and/or price of other industrial raw and finished inputs and/or related services may impact the Registrants' financial results. The Registrants are
dependent on supplies of certain commodities, such as copper and limestone, among others, and industrial materials, and services in order to maintain day-to-day
operations and maintenance of their facilities. Price fluctuations, driven by inflation or other factors, or supply interruptions for these commodities and other items,
could have a negative impact on the amounts charged to customers for the Registrants' utility products and, for DTE Energy, on the profitability of the non-utility
businesses.
Weather significantly affects operations. As weather patterns exhibit increased deviations from historical trends, our utilities may experience financial and
operational challenges. Mild temperatures can result in decreased utilization of the Registrants' assets, lowering income and cash flows. At DTE Electric, high winds,
floods, tornadoes, or ice storms can damage the electric distribution system infrastructure and power generation facilities and require it to perform emergency repairs
and incur material unplanned expenses. The expenses of storm restoration efforts may not be fully recoverable through the regulatory process. Prolonged and/or more
frequent outages caused by increasingly extreme weather may result in decreased revenues and could also negatively impact DTE Energy's reputation and customer
satisfaction or result in increased regulatory oversight. Related damages to customer assets could subject DTE Energy to litigation. DTE Gas can also experience higher
than anticipated expenses from emergency repairs on its gas distribution infrastructure required as a result of weather-related issues.
20

Table of Contents
Unplanned outages at our power plants and other generating assets may be costly. Unforeseen maintenance may be required to safely produce electricity or
comply with environmental regulations. As a result of unforeseen maintenance, the Registrants may be required to make spot market purchases of electricity that exceed
the costs of generation. The Registrants' financial performance may be negatively affected if unable to recover such increased costs.
A work interruption may adversely affect the Registrants. There are several bargaining units for DTE Energy's approximately 4,800 and DTE Electric's
approximately 2,550 represented employees. The majority of represented employees are under contracts that expire in 2027. A union choosing to strike would have an
impact on the Registrants' businesses. The Registrants are unable to predict the effect a work stoppage would have on their costs of operations and financial
performance.
DTE Energy may not achieve the carbon emissions goals of its electric and gas utilities. DTE Energy has announced the voluntary commitments of its electric and
gas utilities to achieve net zero carbon emissions by 2050, along with intermediate emissions reduction goals at various points in the intervening years. DTE Energy
must also comply with the state of Michigan's requirement to meet a 100% clean energy standard by 2040. Technology research and developments, innovations, and
advancements are critical to DTE Energy's ability to achieve these commitments, but they may not evolve as anticipated in order to provide cost-effective alternatives to
traditional energy sources. State and municipal restrictions on the siting of renewable energy assets could also impair efforts to meet our stated targets. Additionally, we
cannot guarantee that we will continue to receive regulatory approval of our capital plans to transition to renewable energy and other new technologies. Other factors
that may impact DTE Energy's ability to achieve these emissions reduction goals include our service territory size and capacity needs remaining in line with current
expectations, the impacts on our business of future regulations or legislation, the price and availability of carbon offsets, adoption of alternative energy products by the
public such as greater use of electric vehicles, greater standardization of emissions reporting, and our ability over time to transition our electric generating portfolio.
DTE Energy's emissions reduction goals require making assumptions that involve risks and uncertainties. Should one or more of these underlying assumptions prove
incorrect, our actual results and ability to achieve our emissions reduction goals could differ materially from expectations. In addition, DTE Energy cannot predict the
ultimate impact of achieving these objectives, or the various implementation aspects on its reliability, availability or price of purchased power, or on its results of
operations, financial condition, or liquidity. DTE Energy could suffer financial loss, reputational damage, litigation, or other negative repercussions if we are unable to
meet our voluntary emissions reductions goals.
Financial, Economic, and Market Risks
DTE Energy's non-utility businesses may not perform to its expectations. DTE Energy relies on non-utility businesses for a portion of earnings and will depend on
the successful execution of new business development in its non-utilities to help achieve overall growth targets. DTE Energy also expects to grow the non-utility
businesses over the long-term by developing or acquiring projects related to renewable energy, carbon capture and sequestration, and customer energy solutions;
however, such opportunities may not materialize as anticipated. If DTE Energy's current and contemplated non-utility investments do not perform at expected levels,
DTE Energy could experience diminished earnings and a corresponding decline in shareholder value.
Adverse changes in the Registrants' credit ratings may negatively affect them. Regional and national economic conditions, increased scrutiny of the energy
industry and regulatory changes, as well as changes in the Registrants' economic performance, could result in credit agencies reexamining their credit ratings. While
credit ratings reflect the opinions of the credit agencies issuing such ratings and may not necessarily reflect actual performance, a downgrade in the Registrants' credit
ratings below investment grade could restrict or discontinue their ability to access capital markets and could result in an increase in their borrowing costs, a reduced
level of capital expenditures, and could impact future earnings and cash flows. In addition, a reduction in the Registrants' credit ratings may require them to post
collateral related to various physical or financially settled contracts for the purchase of energy-related commodities, products, and services, which could impact their
liquidity.
21

Table of Contents
Poor investment performance of pension and other postretirement benefit plan assets and other factors impacting benefit plan costs could unfavorably impact the
Registrants' liquidity and results of operations. The Registrants' costs of providing non-contributory defined benefit pension plans and other postretirement benefit plans
are dependent upon a number of factors, such as the rates of return on plan assets, the level of interest rates used to measure the required minimum funding levels of the
plans, future government regulation, and the Registrants' required or voluntary contributions made to the plans. The performance of the debt and equity markets affects
the value of assets that are held in trust to satisfy future obligations under the Registrants' plans. The Registrants have significant benefit obligations and hold significant
assets in trust to satisfy these obligations. These assets are subject to market fluctuations and will yield uncertain returns, which may fall below the Registrants'
projected return rates. A decline in the market value of the pension and other postretirement benefit plan assets will increase the funding needs under the pension and
other postretirement benefit plans if the actual asset returns do not recover these declines in the foreseeable future. Additionally, the pension and other postretirement
benefit plan liabilities are sensitive to changes in interest rates. If interest rates decrease, the liabilities increase, resulting in increasing benefit expense and funding
needs. Also, if future increases in pension and other postretirement benefit costs as a result of reduced plan assets are not recoverable from the Registrants' utility
customers, the results of operations and financial position of the Registrants could be negatively affected. Without sustained growth in the plan investments over time to
increase the value of plan assets, the Registrants could be required to fund these plans with significant amounts of cash. Such cash funding obligations could have a
material impact on the Registrants' cash flows, financial position, or results of operations.
The Registrants' ability to access capital markets is important. The Registrants' ability to access capital markets is important to operate their businesses and to
fund capital investments. Turmoil in credit markets may constrain the ability of Registrants and their subsidiaries to issue new debt, including commercial paper, and to
refinance existing debt. Macroeconomic events may lead to higher interest rates on debt and could increase financing costs and adversely affect the Registrants' results
of operations. Rising interest rates could also reduce investor interest in DTE Energy's common stock, negatively impacting its share price and increasing its cost of
equity. In addition, the level of borrowing by other energy companies and the market as a whole could limit the Registrants' access to capital markets. The Registrants'
long-term revolving credit facilities do not expire until 2029, but the Registrants regularly access capital markets to refinance existing debt or fund new projects at the
Registrants' utilities and DTE Energy's non-utility businesses, and the Registrants cannot predict the pricing or demand for those future transactions.
Emerging technologies may have a material adverse effect on the Registrants. Advances in technology that produce power or reduce power consumption include
cost-effective renewable energy technologies, distributed generation, energy waste reduction technologies, and energy storage devices. Such developments may impact
the price of energy, may affect energy deliveries as customer-owned generation becomes more cost-effective, may require further improvements to our distribution
systems to address changing load demands, and could make portions of our electric system power supply and/or distribution facilities obsolete prior to the end of their
useful lives. Such technologies could also result in further declines in commodity prices or demand for delivered energy. Each of these factors could materially affect the
Registrants’ results of operations, cash flows, or financial position.
DTE Energy's participation in energy trading markets subjects it to risk. Events in the energy trading industry have increased the level of scrutiny on the energy
trading business and the energy industry as a whole. In certain situations, DTE Energy may be required to post collateral to support trading operations, which could be
substantial. If access to liquidity to support trading activities is curtailed, DTE Energy could experience decreased earnings potential and cash flows. Energy trading
activities take place in volatile markets and expose DTE Energy to risks related to commodity price movements, deviations in weather, and other related risks. DTE
Energy's trading business routinely has speculative trading positions in the market, within strict policy guidelines DTE Energy sets, resulting from the management of
DTE Energy's business portfolio. To the extent speculative trading positions exist, fluctuating commodity prices can improve or diminish DTE Energy's financial results
and financial position. DTE Energy manages its exposure by establishing and enforcing strict risk limits and risk management procedures. During periods of extreme
volatility, these risk limits and risk management procedures may not work as planned and cannot eliminate all risks associated with these activities.
Regional, national, and international economic conditions can have an unfavorable impact on the Registrants. The Registrants' utility and DTE Energy's non-
utility businesses follow the economic cycles of the customers they serve and credit risk of counterparties they do business with. Should the financial conditions of some
of DTE Energy's significant customers deteriorate as a result of regional, national or international economic conditions, reduced volumes of electricity and gas, and
demand for energy services DTE Energy supplies, collections of accounts receivable, reductions in federal and state energy assistance funding, and potentially higher
levels of lost gas or stolen gas and electricity could result in decreased earnings and cash flows.
22

Table of Contents
If DTE Energy's goodwill becomes impaired, it may be required to record a charge to earnings. DTE Energy annually reviews the carrying value of goodwill
associated with acquisitions it has made for impairment. Goodwill is also reviewed on a quarterly basis whenever events or circumstances indicate that the carrying
value of these assets may not be recoverable. Factors that may be considered for purposes of this analysis include a decline in stock price and market capitalization,
slower industry growth rates, or material changes with customers or contracts that could negatively impact future cash flows. DTE Energy cannot predict the timing,
strength, or duration of such changes or any subsequent recovery. If the carrying value of any goodwill is determined to be not recoverable, DTE Energy may take a
non-cash impairment charge, which could materially impact DTE Energy's results of operations and financial position.
The Registrants may not be fully covered by insurance. The Registrants have a comprehensive insurance program in place to provide coverage for various types of
risks, including catastrophic damage as a result of severe weather or other natural disasters, war, terrorism, cyber incidents, liability claims against the Registrants, or a
combination of other significant unforeseen events that could impact the Registrants' operations. Economic losses might not be covered in full by insurance, or the
Registrants' insurers may be unable to meet contractual obligations.
Safety and Security Risks
The Registrants' businesses have safety risks. The Registrants' electric distribution system, power plants, renewable energy equipment, and other facilities, and
DTE Energy's gas distribution system, gas infrastructure, and other facilities, could be involved in incidents that result in injury, death, or property loss to employees,
customers, third parties, or the public. Although the Registrants have insurance coverage for many potential incidents, depending upon the nature and severity of any
incident, they could experience financial loss, damage to their reputation, and negative consequences from regulatory agencies or other public authorities.
Threats of cyber incidents, physical security, and terrorism could affect the Registrants' business. Issues may threaten the Registrants such as cyber incidents,
physical security, or terrorism that may disrupt the Registrants' operations, and could harm the Registrants' operating results.
Information security risks have increased in recent years as a result of the proliferation of new technologies and the increased sophistication and frequency of
cyberattacks, and data security breaches. The Registrants' industry requires the continued operation of sophisticated information and control technology systems and
network infrastructure. All of the Registrants' technology systems are vulnerable to disability or failures due to cyber incidents, physical security threats, acts of war or
terrorism, and other causes, as well as loss of operational control of the Registrants' electric generation and distribution assets and, DTE Energy's gas distribution assets.
The Registrants have experienced, and expect to continue to be subject to, cybersecurity threats and incidents. If the Registrants' information technology systems were
to fail and they were unable to recover in a timely way, the Registrants may be unable to fulfill critical business functions, which could have a material adverse effect on
the Registrants' business, operating results, and financial condition.
Suppliers, vendors, contractors, and information technology providers have access to systems that support the Registrants’ operations and maintain customer and
employee data.  A breach of these third-party systems could adversely affect the business as if it was a breach of our own system.  Also, because the Registrants’
generation and distribution systems are part of an interconnected system, a disruption caused by a cyber incident at another utility, electric generator, system operator, or
commodity supplier could also adversely affect the Registrants’ businesses, operating results, and financial condition.
In addition, the Registrants' generation plants and electrical distribution facilities may be targets of physical security threats or terrorist activities that could disrupt
the Registrants' ability to produce or distribute some portion of their products. The Registrants have increased security as a result of past events and may be required by
regulators or by the future threat environment to make investments in security that the Registrants cannot currently predict.
Failure to maintain the security of personally identifiable information could adversely affect the Registrants. In connection with the Registrants' businesses, they
collect and retain personally identifiable information of their customers, shareholders, and employees. Customers, shareholders, and employees expect that the
Registrants will adequately protect their personal information. The regulatory environment surrounding information security and privacy is increasingly demanding. A
significant theft, loss, or fraudulent use of customer, shareholder, employee, or Registrant data by cybercrime or otherwise, could adversely impact the Registrants'
reputation, and could result in significant costs, fines, and litigation.
23

Table of Contents
General and Other Risks
Failure to attract and retain key executive officers and other skilled professional and technical employees could have an adverse effect on the Registrants’
operations. The Registrants' businesses are dependent on their ability to attract and retain skilled employees. Competition for skilled employees in some areas is high,
and the inability to attract and retain these employees could adversely affect the Registrants' business and future operating results. In addition, the failure of a successful
transfer of knowledge and expertise from any departing employees could negatively impact the Registrants' operations.
DTE Energy relies on cash flows from subsidiaries. DTE Energy is a holding company. Cash flows from the utility and non-utility subsidiaries are required to pay
interest expenses and dividends on DTE Energy debt and securities. Should a major subsidiary not be able to pay dividends or transfer cash flows to DTE Energy, its
ability to pay interest and dividends would be restricted.
Item 1B. Unresolved Staff Comments
None.
Item 1C. Cybersecurity
Risk Management and Strategy
DTE Energy maintains cybersecurity measures designed to protect its physical and digital infrastructure in order to provide safe and reliable delivery of energy to
customers. These measures serve to maintain compliance with regulations and protect the confidentiality, integrity and availability of confidential and proprietary
information, DTE Energy’s computing resources, and the electrical and gas systems.
To protect against cybersecurity threats, DTE Energy employs a dedicated cybersecurity team led by the Chief Information Officer. The cybersecurity team is
responsible for implementing proper safeguards to mitigate the risk of cyber threats, including but not limited to firewalls, continuous monitoring, and training. DTE
Energy also engages with third parties to conduct cybersecurity maturity assessments to provide an independent and objective view of our cybersecurity and assess
opportunities for improvement. The National Institute of Standards and Technology (NIST) Cybersecurity Framework (CSF) is the basis for these assessments to
manage cyber risks, mature and monitor existing security controls, and communicate security posture coherently. The NIST CSF provides a common language to
understand, manage, and express cyber risks internally and externally.
Another component of DTE Energy’s cybersecurity team is the Cybersecurity Defense Center (CSDC), which has the primary responsibility for monitoring and
responding to cybersecurity incidents. The CSDC maintains an incident response plan designed to protect against, detect, evaluate, and respond to and recover from a
cyber incident. The CSDC may receive incident reports from DTE Energy employees, corporate security, or external sources. The incident response plan is intended to
be flexible so it may be adapted to an array of potential scenarios. Depending on the incident, the CSDC may decide to engage external resources for assistance with
responding to the incident. DTE Energy regularly conducts exercises to help ensure the plan’s effectiveness and overall preparedness.
DTE Energy engages third-party service providers to assist with managing various aspects of its business. These service providers are subject to due diligence
reviews of their information security programs prior to onboarding. DTE Energy also contractually requires service providers with access to its information technology
(IT) systems, sensitive business data, or personal information to implement and maintain appropriate security controls and restricts their ability to use such data for
purposes other than to provide services to DTE Energy, except as required by law. Third-party service providers are also contractually required to notify DTE Energy
promptly of cyber incidents that may affect any systems or data. DTE Energy collaborates with its service providers to help determine whether their information security
protocols are sufficient. If a service provider experiences a cyber incident, DTE Energy monitors their compliance with our security requirements; however, DTE
Energy may not have the ability in all cases to effectively oversee the implementation of these control measures.
24

Table of Contents
The CSDC monitors and responds to actual and potential compromises from third-party service providers. Access from a potentially compromised third-party is
restricted until DTE Energy receives confirmation the compromise has been mitigated.
DTE Energy has experienced, and expects to continue to be subject to, cybersecurity threats and incidents. As of December 31, 2024, cybersecurity risks have not
materially affected the Registrants’ business strategy, results of operations, or financial condition. For additional discussion of the risks related to cybersecurity threats
and incidents, see Item 1A. "Risk Factors."
Governance
DTE Energy has an enterprise risk management program to reduce overall risk, including risks related to cybersecurity, through comprehensive risk assessments
and execution of corresponding mitigation plans. Risks are reported and managed through various internal committees, which meet regularly and report at least annually
to the Board of Directors. These committees include:
•
The Risk Management Committee (RMC) is chaired by the Chief Executive Officer and comprised of the Chief Financial Officer, Chief Legal Officer,
General Auditor, and other senior officers. The RMC directs the development and maintenance of comprehensive risk management policies and procedures.
The RMC also sets, reviews, and monitors risk limits for enterprise-level risk and other exposures
•
The Operational Risk and Resilience (ORR) Committee is chaired by the President and Chief Operating Officer and comprised of operational leaders in DTE
Energy’s business units. The ORR is responsible for managing operational risks including safety, reliability, and cybersecurity at DTE Energy’s generation
plants, substations, and other operating sites
•
The Technology Cybersecurity Committee (TCC) is a sub-committee of the ORR that focuses on information and operational technology risks related to
cybersecurity, chaired by operational leaders in DTE Energy’s business units and includes the Chief Information Officer
Members of the Board of Directors serve roles on various committees responsible for their respective oversight and risk management. The Audit Committee of the
Board of Directors, comprised solely of independent directors, is responsible for reviewing DTE Energy’s cybersecurity risks, the results of any cybersecurity risk
assessments and audits, and reports of investigations into significant events presented by DTE Energy’s IT department. The Audit Committee reports to the Board of
Directors and may include any significant matters involving cybersecurity within its reporting. All members of the Board of Directors, including the Audit Committee,
have either managerial knowledge or working knowledge of technology and cybersecurity matters.
DTE Energy’s Chief Information Officer leads the cybersecurity team and has responsibility for assessing and managing cybersecurity risks. The Chief
Information Officer has held this position for over 10 years and has decades of experience in IT, including oversight of information protection security (IPS). The IPS
cybersecurity team is also led by two full-time directors with over 40 combined years of industry experience, including (1) the director of cybersecurity operations
responsible for the CSDC, identity and access assurance, and cloud security and (2) the IPS director of cybersecurity strategy, risk, and engagement who is also
responsible for engagement and outreach to internal and external stakeholders.
The Chief Information Officer provides regular updates to the Audit Committee and senior leaders regarding DTE Energy’s management of cyber risks, including
but not limited to the status of various training metrics to safeguard against phishing, malware, and other cyber threats. The Chief Information Officer also provides an
annual cybersecurity update directly to the Board of Directors. If cybersecurity risks arise, the CSDC executes the incident response plan and communicates the
appropriate details to executive management, the Board of Directors, or any related committees.
A cybersecurity incident may also require various levels of external reporting. The CSDC coordinates with the legal department and controller’s organization in
reporting incidents externally. Depending on the nature of the incident, reporting may be required to various federal and state government agencies. DTE Energy has
forged trusted partnerships with such agencies and with other companies and organizations to share best practices, tools, and threat information. This includes partnering
with others in the utilities industry to form the Electricity Subsector Coordination Council (ESCC). The ESCC is the principal liaison between the energy sector and the
federal government in coordinating efforts to prepare for and respond to any threats to critical infrastructure.

Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations
The following combined discussion is separately filed by DTE Energy and DTE Electric. However, DTE Electric does not make any representations as to
information related solely to DTE Energy or the subsidiaries of DTE Energy other than itself.
EXECUTIVE OVERVIEW
DTE Energy is a diversified energy company with 2024 Operating Revenues of approximately $12.5 billion and Total Assets of approximately $48.8 billion. DTE
Energy is the parent company of DTE Electric and DTE Gas, regulated electric and natural gas utilities engaged primarily in the business of providing electricity and
natural gas sales, distribution, and storage services throughout Michigan. DTE Energy also operates two energy-related non-utility segments with operations throughout
the United States.
Management’s Discussion and Analysis of Financial Condition and Results of Operations below reflect DTE Energy’s continuing operations, unless noted
otherwise. The following table summarizes DTE Energy's financial results:

The increase in 2024 Net Income Attributable to DTE Energy Company was primarily due to higher earnings in the Electric segment, partially offset by lower
earnings in the Energy Trading, Gas, and DTE Vantage segments and Corporate and Other. The increase in 2023 Net Income Attributable to DTE Energy Company was
primarily due to higher earnings in the Energy Trading, DTE Vantage, and Gas segments, partially offset by lower earnings in the Electric segment and Corporate and
Other.
STRATEGY
DTE Energy's strategy is to achieve long-term earnings per share growth with a strong balance sheet and attractive dividend.
DTE Energy's utilities are investing capital to support a modern, reliable grid and cleaner, affordable energy through investments in base infrastructure and new
generation. Increasing intensity of windstorms and other weather events, coupled with increasing electric vehicle adoption and potential for data centers, will drive a
continued need for substantial grid investment over the long-term.
DTE Energy plans to reduce the carbon emissions of its electric utility operations by 65% in 2028, 85% in 2032, and 90% by 2040 from 2005 carbon emissions
levels. DTE Energy plans to end its use of coal-fired power plants in 2032 and is committed to a net zero carbon emissions goal by 2050 for its electric and gas utility
operations.
Additionally, as a result of legislation passed by the state of Michigan in the fourth quarter 2023, DTE Energy will be required to meet a 100% clean energy
portfolio standard by 2040. Clean energy sources include renewables, nuclear, and natural gas-fired plants equipped with a carbon capture and storage system that is at
least 90% effective in reducing carbon emissions to the atmosphere. The legislation also requires 50% of an electric utility's energy to be generated from renewable
sources by 2030 and 60% by 2035. DTE Energy is currently assessing the impacts of this legislation and will include updates in its next Integrated Resource Plan,
currently planned for 2026, to comply with the new requirements.
To achieve carbon reduction goals at the electric utility, DTE Energy will continue its transition away from coal-powered energy sources and is replacing or
offsetting the generation from these facilities with renewable energy, natural gas, battery storage, and energy waste reduction initiatives. Refer to the "Capital
Investments" section below for further discussion regarding DTE Energy's retirement of its aging coal-fired plants and transition to renewable energy and other sources.
Over the long-term, DTE Energy is also monitoring and pursuing the advancement of emerging technologies such as long-duration storage, modular nuclear reactors,
hydrogen, and carbon capture and sequestration, and how these technologies may support clean, reliable generation and customer affordability.

Table of Contents
For the gas utility, DTE Energy aims to cut carbon emissions across the entire value chain. DTE Energy plans to reduce the carbon emissions from its gas utility
operations by 65% by 2030 and 80% by 2040, and is committed to a goal of net zero emissions by 2050 from internal gas operations and gas suppliers. To achieve net
zero, DTE Energy is working to source gas with lower methane intensity, reduce emissions through its gas main renewal and pipeline integrity programs, and if
necessary, use carbon offsets to address any remaining emissions. DTE Energy also aims to help DTE Gas customers reduce their emissions by approximately 35% by
2040 by increasing energy efficiency, pursuing advanced technologies such as hydrogen and carbon capture and sequestration, and through the CleanVision Natural Gas
Balance program which provides customers the option to use carbon offsets and renewable natural gas.
DTE Energy expects that these initiatives at the electric and gas utilities will continue to provide significant opportunities for capital investments and result in
earnings growth. DTE Energy is focused on executing its plans to achieve operational excellence and customer satisfaction with a focus on customer affordability. To
support its goals for customer affordability, DTE Energy is working to implement operational efficiencies and optimize opportunities from the Inflation Reduction Act
to generate tax credits relating to renewable energy, nuclear generation, energy storage, and carbon capture and sequestration. These tax credits may reduce the cost of
owning related assets and reduce customer rate impacts from any future cost recoveries. DTE Energy's utilities operate in a constructive regulatory environment and
have solid relationships with their regulators.
DTE Energy also has significant investments in non-utility businesses and expects growth opportunities in its DTE Vantage segment. DTE Energy employs
disciplined investment criteria when assessing growth opportunities that leverage its assets, skills, and expertise, and provides attractive returns and diversity in earnings
and geography. Specifically, DTE Energy invests in targeted markets with attractive competitive dynamics where meaningful scale is in alignment with its risk profile.
A key priority for DTE Energy is to maintain a strong balance sheet which facilitates access to capital markets and reasonably priced financing. Growth will be
funded through internally generated cash flows and the issuance of debt and equity. DTE Energy has an enterprise risk management program that, among other things, is
designed to monitor and manage exposure to earnings and cash flow volatility related to commodity price changes, interest rates, and counterparty credit risk.
CAPITAL INVESTMENTS
DTE Energy's utility businesses will require significant capital investments to maintain and improve the electric generation and electric and natural gas distribution
infrastructure and to comply with environmental regulations and achieve goals for carbon emission reductions. Capital plans may be regularly updated as these
requirements and goals evolve and may be subject to regulatory approval.
DTE Electric's capital investments over the 2025-2029 period are estimated at $24 billion, comprised of $10 billion for distribution infrastructure, $4 billion for
base infrastructure, and $10 billion for cleaner generation including renewables.
DTE Electric has retired all eleven coal-fired generation units at the Trenton Channel, River Rouge, and St. Clair facilities, and plans to repurpose the Trenton
Channel plant to a battery energy storage system in 2026. DTE Electric has also announced plans to retire its remaining six coal-fired generating units, including
converting the two units at the Belle River facility from a base load coal plant to a natural gas peaking resource in 2025-2026. The four units at the Monroe facility are
expected to be retired in two stages in 2028 and 2032. Generation from the retired facilities will continue to be replaced or offset with a combination of renewables,
energy waste reduction, demand response, battery storage, and natural gas fueled generation.
DTE Gas' capital investments over the 2025-2029 period are estimated at $4.0 billion, comprised of $2.5 billion for base infrastructure and $1.5 billion for the gas
renewal program, which includes main and service renewals, meter move-out, and pipeline integrity projects.
DTE Electric and DTE Gas plan to seek regulatory approval for capital expenditures consistent with ratemaking treatment.
DTE Energy's non-utility businesses' capital investments are primarily for expansion, growth, and ongoing maintenance in the DTE Vantage segment, including
approximately $1.5 billion to $2.0 billion from 2025-2029 for custom energy solutions and renewable energy, while expanding into carbon capture and sequestration.

ENVIRONMENTAL MATTERS
The Registrants are subject to extensive environmental regulations, including those addressing climate change. Additional costs may result as the effects of various
substances on the environment are studied and governmental regulations are developed and implemented. Actual costs to comply could vary substantially. The
Registrants expect to continue recovering environmental costs related to utility operations through rates charged to customers, as authorized by the MPSC.
Increased costs for energy produced from traditional coal-based sources due to recent, pending, and future regulatory initiatives could also increase the economic
viability of energy produced from renewable, natural gas fueled generation, and/or nuclear sources, energy waste reduction initiatives, and the potential development of
market-based trading of carbon instruments.
Refer to the "Environmental Matters" section within Items 1. and 2. Business and Properties and Note 17 to the Consolidated Financial Statements, "Commitments
and Contingencies," for further discussion of Environmental Matters.
OUTLOOK
The next few years will be a period of rapid change for DTE Energy and for the energy industry. DTE Energy's strong utility base, combined with its integrated
non-utility operations, position it well for long-term growth.
Looking forward, DTE Energy will focus on several areas that are expected to improve future performance:
•
electric and gas customer satisfaction;
•
electric distribution system reliability;
•
new electric generation and storage;
•
gas distribution system renewal;
•
reducing carbon emissions at the electric and gas utilities;
•
rate competitiveness and affordability;
•
regulatory stability and investment recovery for the electric and gas utilities;
•
strategic investments in growth projects at DTE Vantage;
•
employee engagement, health, safety and wellbeing, and diversity, equity, and inclusion;
•
cost structure optimization across all business segments; and
•
cash, capital, and liquidity to maintain or improve financial strength.
DTE Energy will continue to pursue opportunities to grow its businesses in a disciplined manner if it can secure opportunities that meet its strategic, financial, and
risk criteria.

Operation and maintenance expense increased $22 million in 2024 and decreased $147 million in 2023. The increase in 2024 was primarily due to one-time costs
of $32 million resulting from the voluntary separation incentive program, higher RPS expense of $25 million, higher EWR expense of $17 million, higher uncollectible
expense of $12 million, higher corporate support costs of $12 million, higher sales and marketing expense of $10 million, higher legal expense of $9 million, higher
planning and development expense of $7 million, and higher plant generation expense of $3 million, partially offset by lower distribution operations expense of $106
million (primarily due to lower storm restoration costs).
The decrease in 2023 was primarily due to lower plant generation expense of $108 million (primarily due to lower outage costs and coal plant retirements), lower
benefits and other compensation expense of $67 million, lower corporate support costs of $55 million, and lower legal expense of $14 million. These decreases were
partially offset by higher distribution operations expense of $99 million, which was primarily due to higher storm restoration costs.
Depreciation and amortization expense increased $107 million in 2024 and $122 million in 2023. In 2024, the increase was primarily due to a $103 million
increase from a higher depreciable base. In 2023, the increase was primarily due to a $113 million increase from a higher depreciable base and an increase of $10
million associated with the TRM.
Taxes other than income increased $14 million 2024 and had no change in 2023. The increase in 2024 was primarily due to higher property taxes.
Asset (gains) losses and impairments, net decreased $15 million in 2024 and increased $19 million in 2023. The change in both periods was primarily due to
MPSC disallowances of previously recorded capital expenditures, including $12 million from the January 2025 rate order written off in 2024 and $25 million from the
December 2023 rate order written off in 2023.
Other (Income) and Deductions increased $32 million in 2024 and $40 million in 2023. The increase in 2024 was primarily due to higher net interest expense of
$79 million, partially offset by higher AFUDC equity of $44 million and lower non-operating retirement benefits of $7 million. The increase in 2023 was primarily due
to higher net interest expense of $48 million and higher non-operating retirement benefits expense of $26 million, partially offset by a favorable change in investment
earnings of $19 million and higher AFUDC equity of $14 million.
Income Tax Expense (Benefit) changed $109 million in 2024 and increased $53 million in 2023. The change in 2024 was primarily due to an increase in tax
credits, partially offset by higher earnings. The increase in 2023 was primarily due to lower amortization of the TCJA regulatory liability, partially offset by lower
earnings.

Operation and maintenance expense increased $29 million in 2024 and decreased $35 million in 2023. The 2024 increase was primarily due to a new project in
the On-site business of $7 million and higher costs in the On-site business of $11 million, Renewables business of $6 million, and Steel business of $6 million. The 2023
decrease was primarily due to lower operating costs in the Renewables business of $13 million and lower operating costs in the On-site business of $24 million, which
was primarily driven by a decrease of $11 million due to the sale of a project.
Depreciation and amortization increased $6 million in 2024 and $1 million in 2023. The increase in 2024 was primarily due to new projects in the Renewables
business.
Asset (gains) losses and impairments, net changed by $20 million in 2024 from the net gain of $10 million in 2023, and changed by $3 million in 2023 from the
net gain of $7 million in 2022. The change in 2024 was primarily due to the write-off of carbon capture and sequestration assets of $10 million and net gains of $10
million from 2023 that did not repeat in the current year.
The change in 2023 was primarily due to a gain of $17 million resulting from a change in estimate of an asset retirement obligation in the Steel business, partially
offset by asset write-offs in other business units of $7 million. The net gain for 2023 was also partially offset by $7 million due to settlement of contingent consideration
relating to a 2017 acquisition in the Renewables business, which resulted in a loss of $2 million in 2023 compared to a gain of $5 million recorded in 2022.
Other (Income) and Deductions increased $37 million in 2024 and $12 million in 2023. The 2024 increase was primarily due to higher interest income of $41
million associated with a new project in the On-site business and a gain in the Renewable business of $25 million attributed to the sale of a partnership interest, partially
offset by a write-off of an equity investment in the Renewables business due to impairment of $23 million and higher net interest expense of $9 million. The 2023
increase was primarily due to $7 million higher equity investment earnings in the Renewables business and $4 million higher interest income associated with a new
project in the Steel business.
Income Taxes — Expense decreased $4 million in 2024 and increased $11 million in 2023. The decrease in 2024 was primarily due to a $6 million impact from
lower pre-tax income, partially offset by a $2 million higher deferred tax expense related to the reduction in tax basis on property that generated ITCs. The increase in
2023 was primarily due to a $6 million impact from higher pre-tax income. The increase was also due to $5 million higher deferred tax expense related to the reduction
in tax basis on property that generated ITCs.
Income Taxes — Tax Credits increased $11 million in 2024 and $51 million in 2023. The increase in 2024 was primarily due to a new project in the On-site
business of $60 million, partially offset by 2023 tax credits of $48 million from new projects in the prior year that did not repeat. The increase in 2023 was primarily due
to ITCs of $39 million related to new projects in the Renewables business and $9 million for a new project in the On-site business.

Outlook — In December 2024, DTE Vantage entered into a series of agreements with a large industrial customer to design, construct, own, and operate certain
energy infrastructure assets at the customer's planned battery manufacturing plant in Michigan. The project is expected to begin construction in 2025 and achieve
commercial operations in 2026 for a term of 20 years.
DTE Vantage will continue to leverage its extensive energy-related operating experience and project management capability to develop additional renewable
natural gas projects and other projects that provide customer specific energy solutions. DTE Vantage is also developing decarbonization opportunities relating to carbon
capture and sequestration projects.

Operation and maintenance expense increased $5 million in 2024 and $14 million in 2023. The increase in 2024 and 2023 was primarily due to higher
compensation costs.
Natural gas structured transactions typically involve a physical purchase or sale of natural gas in the future and/or natural gas basis financial instruments which are
derivatives and a related non-derivative pipeline transportation contract. These gas structured transactions can result in significant earnings volatility as the derivative
components are marked-to-market without revaluing the related non-derivative contracts.
Operating Income (Loss) decreased $268 million in 2024, which includes a $167 million unfavorable change in timing-related gains primarily related to gas
strategies subject to reversal in future periods as the underlying contracts settle. The decrease also includes a $107 million unfavorable change in timing-related gains
and losses primarily related to gas strategies that were recognized in previous periods and subsequently reversed as the underlying contracts settled.
Operating Income (Loss) increased $558 million in 2023, which includes a $429 million favorable change in timing-related gains and losses primarily related to
gas strategies subject to reversal in future periods as the underlying contracts settle. The increase also includes a $19 million favorable change in timing-related losses
primarily related to gas strategies that were recognized in previous periods and subsequently reversed as the underlying contracts settled.
Other (Income) and Deductions increased $13 million in 2024 and decreased $13 million in 2023. The increase in 2024 was primarily due to $22 million of higher
contributions to not-for-profit organizations, partially offset by higher net interest income of $9 million. The decrease in 2023 was primarily due to $10 million of lower
contributions to not-for-profit organizations and lower net interest expense of $3 million.
Outlook — In the near-term, Energy Trading expects market conditions to remain challenging. The profitability of this segment may be impacted by the volatility
in commodity prices and the uncertainty of impacts associated with regulatory changes, and changes in operating rules of RTOs. Significant portions of the Energy
Trading portfolio are economically hedged. Most financial instruments, physical power and natural gas contracts, and certain environmental contracts are deemed
derivatives; whereas, natural gas and environmental inventory, contracts for pipeline transportation, storage assets, and some environmental contracts are not
derivatives. As a result, Energy Trading will experience earnings volatility as derivatives are marked-to-market without revaluing the underlying non-derivative
contracts and assets. Energy Trading's strategy is to economically manage the price risk of these underlying non-derivative contracts and assets with futures, forwards,
swaps, and options. This results in gains and losses that are recognized in different interim and annual accounting periods.

CORPORATE AND OTHER
Corporate and Other includes various holding company activities, holds certain non-utility debt, and holds certain investments, including investments supporting
regional development and economic growth. The 2024 net loss of $185 million represents an increase of $27 million from the 2023 net loss of $158 million. This
increase was primarily due to higher net interest expense and higher state income taxes, partially offset by lower equity investment losses.
The 2023 net loss of $158 million represents an increase of $13 million from the 2022 net loss of $145 million. This increase was primarily due to higher net
interest expense, partially offset by lower equity investment losses, lower valuation allowances, lower corporate overhead costs, and lower benefits expense.
Outlook — Corporate and Other will continue to support DTE Energy's goals to achieve long-term earnings growth by managing corporate costs such as interest
and tax expense. Corporate and Other will also continue to support DTE Energy in achieving a strong balance sheet, access to capital markets, and implementation of a
financing plan that includes interest rate management in order to manage interest costs.
CAPITAL RESOURCES AND LIQUIDITY
Cash Requirements
DTE Energy uses cash to maintain and invest in the electric and natural gas utilities, to grow the non-utility businesses, to retire and pay interest on long-term debt,
and to pay dividends. DTE Energy believes it will have sufficient internal and external capital resources to fund anticipated capital and operating requirements. DTE
Energy expects that cash from operations in 2025 will be approximately $3.3 billion. DTE Energy anticipates base level utility capital investments, including
environmental, renewable, and energy waste reduction expenditures, and expenditures for non-utility businesses of approximately $4.9 billion in 2025. DTE Energy
plans to seek regulatory approval to include utility capital expenditures in regulatory rate base consistent with prior treatment. Capital spending for growth of existing or
new non-utility businesses will depend on the existence of opportunities that meet strict risk-return and value creation criteria.
Refer below for analysis of cash flows relating to operating, investing, and financing activities, which reflect DTE Energy's change in financial condition. Any
significant non-cash items are included in the Supplemental disclosure of non-cash investing and financing activities within the Consolidated Statements of Cash Flows.

Cash from Operating Activities
A majority of DTE Energy's operating cash flows are provided by the electric and natural gas utilities, which are significantly influenced by factors such as
weather, electric retail access, regulatory deferrals, regulatory outcomes, economic conditions, changes in working capital, and operating costs.
Net cash from operations increased $423 million in 2024. The increase was primarily due to higher cash from working capital items and an increase in
Depreciation and amortization, partially offset by a decrease in cash related to Allowance for equity funds used during construction.
The change in working capital items in 2024 was primarily due to an increase in cash related to Accounts payable, Derivative assets and liabilities, and Other
current and noncurrent assets and liabilities, partially offset by a decrease in cash related to Accounts receivable net, Inventories, Accrued pension liability, and Accrued
postretirement liability.
41

Table of Contents
Net cash from operations increased $1.2 billion in 2023. The increase was primarily due to higher cash from working capital items and increases in Net income,
Depreciation and amortization, and Deferred income taxes.
The change in working capital items in 2023 was primarily due to an increase in cash related to Accounts receivable, net and Regulatory assets and liabilities,
partially offset by a decrease in cash related to Prepaid postretirement benefit costs, Accounts payable, Derivative assets and liabilities, and Other current and noncurrent
assets and liabilities.
Cash used for Investing Activities
Cash inflows associated with investing activities are primarily generated from the sale of assets, while cash outflows are the result of plant and equipment
expenditures and acquisitions. In any given year, DTE Energy looks to realize cash from under-performing or non-strategic assets or matured, fully valued assets.
Capital spending within the utility businesses is primarily to maintain and improve electric generation and the electric and natural gas distribution infrastructure,
and to comply with environmental regulations and renewable energy goals.
Capital spending within the non-utility businesses is primarily for ongoing maintenance, expansion, and growth. DTE Energy looks to make growth investments
that meet strict criteria in terms of strategy, management skills, risks, and returns. All new investments are analyzed for their rates of return and cash payback on a risk
adjusted basis. DTE Energy has been disciplined in how it deploys capital and will not make investments unless they meet the criteria. For new business lines, DTE
Energy initially invests based on research and analysis. DTE Energy starts with a limited investment, evaluates the results, and either expands or exits the business based
on those results. In any given year, the amount of growth capital will be determined by the underlying cash flows of DTE Energy, with a clear understanding of any
potential impact on its credit ratings.
Net cash used for investing activities increased $856 million in 2024 and $664 million in 2023 due primarily to increases in utility plant and equipment
expenditures and cash used related to Notes receivable.
Cash from Financing Activities
DTE Energy relies on both short-term borrowing and long-term financing as a source of funding for capital requirements not satisfied by its operations.
DTE Energy's strategy is to have a targeted debt portfolio blend of fixed and variable interest rates and maturity. DTE Energy targets balance sheet financial
metrics to ensure it is consistent with the objective of a strong investment grade debt rating.
Net cash from financing activities increased $462 million in 2024. The increase was primarily due to an increase in Issuance of long-term debt, net of issuance
costs, partially offset by decreases in cash related to Redemption of long-term debt and Short-term borrowings, net.
Net cash from financing activities decreased $579 million in 2023. The decrease was primarily due to the Issuance of common stock in 2022 and a decrease in
Short-term borrowings, net, partially offset by an increase in Issuance of long-term debt, net of issuance costs.
Outlook
Sources of Cash
DTE Energy expects cash flows from operations to increase over the long-term, primarily as a result of growth from the utility and non-utility businesses. Growth
in the utilities is expected to be driven primarily by capital spending which will increase the base from which rates are determined. Further, the Inflation Reduction Act
allows for extended tax benefits for renewable technologies, increased rates for PTCs and an option to claim PTCs for solar projects, expanded qualified ITC facilities to
include standalone energy storage, and allows for the transfer of tax credits generated from renewable projects. DTE Electric expects to continue to monetize these tax
credits to generate cash flows in the near-term. DTE Energy expects long-term growth in sales related to vehicle electrification, but no significant impacts in the near-
term. Non-utility growth is expected from additional investments in the DTE Vantage segment, primarily related to renewable energy and custom energy solutions,
while expanding into carbon capture and sequestration. DTE Vantage also expects enhanced growth opportunities in decarbonization as a result of the Inflation
Reduction Act, including tax credits for renewable natural gas and carbon capture projects.

Table of Contents
DTE Energy's utilities may be impacted by the timing of collection or refund of various recovery and tracking mechanisms as a result of timing of MPSC orders.
Energy prices are likely to be a source of volatility with regard to working capital requirements for the foreseeable future. DTE Energy continues its efforts to identify
opportunities to improve cash flows through working capital initiatives and maintaining flexibility in the timing and extent of long-term capital projects.
At the discretion of management and depending upon economic and financial market conditions, DTE Energy expects to issue up to $100 million of equity in
2025. DTE Energy anticipates these discretionary equity issuances would be made through contributions to the dividend reinvestment plan and/or employee benefit
plans.
Over the long-term, some additional equity may be needed beginning in 2028 to support long-term growth. DTE Energy will continue to evaluate equity needs on
an annual basis. DTE Energy currently expects its primary source of long-term financing to be the issuance of debt and is monitoring changes in interest rates and
impacts on the cost of borrowing.
Uses of Cash
DTE Energy has $1.3 billion in long-term debt, including securitization bonds and finance leases, maturing in the next twelve months. Repayment of the debt is
expected to be made through internally generated funds and the issuance of short-term and/or long-term debt.
DTE Energy has paid quarterly cash dividends for more than 100 consecutive years and expects to continue paying regular cash dividends in the future, including
approximately $0.9 billion in 2025. Any payment of future dividends is subject to approval by the Board of Directors and may depend on DTE Energy's future earnings,
capital requirements, and financial condition. Over the long-term, DTE Energy expects continued dividend growth and is targeting a payout ratio consistent with pure-
play utility companies. Dividends are subject to certain restrictions as discussed in Note 15 to the Consolidated Financial Statements, "Short-Term Credit Arrangements
and Borrowings." However, these restrictions are not expected to impact DTE Energy's planned dividend payments.
Various subsidiaries and equity investees of DTE Energy have entered into derivative and non-derivative contracts which contain ratings triggers and are
guaranteed by DTE Energy. These contracts contain provisions which allow the counterparties to require that DTE Energy post cash or letters of credit as collateral in
the event that DTE Energy's credit rating is downgraded below investment grade. Certain of these provisions (known as "hard triggers") state specific circumstances
under which DTE Energy can be required to post collateral upon the occurrence of a credit downgrade, while other provisions (known as "soft triggers") are not as
specific. For contracts with soft triggers, it is difficult to estimate the amount of collateral which may be requested by counterparties and/or which DTE Energy may
ultimately be required to post. The amount of such collateral which could be requested fluctuates based on commodity prices (primarily natural gas, power, and
environmental) and the provisions and maturities of the underlying transactions. As of December 31, 2024, DTE Energy's contractual obligation to post collateral in the
form of cash or letters of credit in the event of a downgrade to below investment grade, under both hard trigger and soft trigger provisions, was $360 million.
For cash obligations related to leases and future purchase commitments, refer to Note 16 and Note 17 to the Consolidated Financial Statements, "Leases." and
"Commitments and Contingencies," respectively. Purchase commitments include capital expenditures that are contractually obligated. Also refer to the "Capital
Investments" section above for additional information on DTE Energy's capital strategy and estimated spend over the next five years.

Liquidity
DTE Energy has approximately $1.9 billion of available liquidity at December 31, 2024, consisting primarily of cash and cash equivalents and amounts available
under unsecured revolving credit agreements.
DTE Energy believes it will have sufficient operating flexibility, cash resources and funding sources to maintain adequate liquidity and to meet future operating
cash and capital expenditure needs. However, virtually all DTE Energy's businesses are capital intensive, or require access to capital, and the inability to access adequate
capital could adversely impact earnings and cash flows.
Credit Ratings
Credit ratings are intended to provide banks and capital market participants with a framework for comparing the credit quality of securities and are not a
recommendation to buy, sell, or hold securities. DTE Energy, DTE Electric, and DTE Gas' credit ratings affect their costs of capital and other terms of financing, as well
as their ability to access the credit and commercial paper markets. DTE Energy, DTE Electric, and DTE Gas' management believes that the current credit ratings provide
sufficient access to capital markets. However, disruptions in the banking and capital markets not specifically related to DTE Energy, DTE Electric, and DTE Gas may
affect their ability to access these funding sources or cause an increase in the return required by investors.
As part of the normal course of business, DTE Electric, DTE Gas, and various non-utility subsidiaries of DTE Energy routinely enter into physical or financially
settled contracts for the purchase and sale of electricity, natural gas, coal, capacity, storage, and other energy-related products and services. Certain of these contracts
contain provisions which allow the counterparties to request that DTE Energy posts cash or letters of credit in the event that the senior unsecured debt rating of DTE
Energy is downgraded below investment grade. The amount of such collateral which could be requested fluctuates based upon commodity prices and the provisions and
maturities of the underlying transactions and could be substantial. Also, upon a downgrade below investment grade, DTE Energy, DTE Electric, and DTE Gas could
have restricted access to the commercial paper market, and if DTE Energy is downgraded below investment grade, the non-utility businesses could be required to
restrict operations due to a lack of available liquidity. A downgrade below investment grade could potentially increase the borrowing costs of DTE Energy, DTE
Electric, and DTE Gas and their subsidiaries and may limit access to the capital markets. The impact of a downgrade will not affect DTE Energy, DTE Electric, and
DTE Gas' ability to comply with existing debt covenants. While DTE Energy, DTE Electric, and DTE Gas currently do not anticipate such a downgrade, they cannot
predict the outcome of current or future credit rating agency reviews.
CRITICAL ACCOUNTING ESTIMATES
The preparation of the Registrants' Consolidated Financial Statements in conformity with generally accepted accounting principles requires that management apply
accounting policies and make estimates and assumptions that affect the results of operations and the amounts of assets and liabilities reported in the Consolidated
Financial Statements. The Registrants' management believes that the areas described below require significant judgment in the application of accounting policy or in
making estimates and assumptions in matters that are inherently uncertain and that may change in subsequent periods. Additional discussion of these accounting policies
can be found in the Combined Notes to Consolidated Financial Statements in Item 8 of this Report.
Regulation
A significant portion of the Registrants' businesses are subject to regulation. This results in differences in the application of generally accepted accounting
principles between regulated and non-regulated businesses. DTE Electric and DTE Gas are required to record regulatory assets and liabilities for certain transactions
that would have been treated as revenue or expense in non-regulated businesses. Future regulatory changes or changes in the competitive environment could result in the
discontinuance of this accounting treatment for regulatory assets and liabilities for some or all of the Registrants' businesses. The Registrants' management believes that
currently available facts support the continued use of regulatory assets and liabilities and that all regulatory assets and liabilities are recoverable or refundable in the
current rate environment.
See Note 8 to the Consolidated Financial Statements, "Regulatory Matters."

Table of Contents
Derivatives
Derivatives are generally recorded at fair value and shown as Derivative assets or liabilities. Changes in the fair value of the derivative instruments are recognized
in earnings in the period of change. The normal purchases and normal sales exception requires, among other things, physical delivery in quantities expected to be used
or sold over a reasonable period in the normal course of business. Contracts that are designated as normal purchases and normal sales are not recorded at fair value.
Substantially all of the commodity contracts entered into by DTE Electric and DTE Gas meet the criteria specified for this exception.
Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the
measurement date in a principal or most advantageous market. Fair value is a market-based measurement that is determined based on inputs, which refer broadly to
assumptions that market participants use in pricing assets or liabilities. These inputs can be readily observable, market corroborated, or generally unobservable inputs.
The Registrants make certain assumptions they believe that market participants would use in pricing assets or liabilities, including assumptions about risk, and the risks
inherent in the inputs to valuation techniques. Credit risk of the Registrants and their counterparties is incorporated in the valuation of assets and liabilities through the
use of credit reserves, the impact of which was immaterial at December 31, 2024 and 2023. The Registrants believe they use valuation techniques that maximize the use
of observable market-based inputs and minimize the use of unobservable inputs.
The fair values the Registrants calculate for their derivatives may change significantly as inputs and assumptions are updated for new information. Actual cash
returns realized on derivatives may be different from the results the Registrants estimate using models. As fair value calculations are estimates based largely on
commodity prices, the Registrants perform sensitivity analyses on the fair values of forward contracts. See the sensitivity analysis in Item 7A. of this report,
"Quantitative and Qualitative Disclosures About Market Risk." See also the "Fair Value" section herein.
See Notes 11 and 12 to the Consolidated Financial Statements, "Fair Value" and "Financial and Other Derivative Instruments," respectively.
Goodwill
DTE Energy's reporting units have goodwill or allocated goodwill resulting from business combinations. DTE Energy performs an impairment test for each of the
reporting units annually or whenever events or circumstances indicate that the value of goodwill may be impaired.
In performing the impairment test, DTE Energy compares the fair value of the reporting unit to its carrying value including goodwill. If the carrying value
including goodwill were to exceed the fair value of a reporting unit, an impairment loss would be recognized. A goodwill impairment loss is measured as the amount by
which a reporting unit's carrying value exceeds fair value, not to exceed the carrying amount of goodwill.
DTE Energy estimates the reporting unit's fair value using standard valuation techniques, including techniques which use estimates of projected future results and
cash flows to be generated by the reporting unit. For all reporting units except Energy Trading, the fair values were calculated using a weighted combination of the
income approach, which estimates fair value based on discounted cash flows, and the market approach, which estimates fair value based on market comparables within
the utility and energy industries. For the Energy Trading reporting unit, only the income approach was used due to the lack of comparable market information.
Discounted cash flows used in the income approach are based on DTE Energy's internal business plan for the next five years plus a terminal value. DTE Energy
capitalizes the terminal value for each reporting unit using a weighted average cost of capital (WACC) less an assumed long-term growth rate. The income approach
cash flow valuations involve a number of estimates that require broad assumptions and significant judgment by management regarding future performance.
One of the most significant assumptions utilized in determining the fair value of reporting units under the market approach is implied market multiples for certain
peer companies. Management selects comparable peers based on each peer’s primary business mix, operations, and market capitalization compared to the applicable
reporting unit and calculates implied market multiples based on available projected earnings guidance and peer company market values as of the test date.
45

Table of Contents
DTE Energy performs an annual impairment test each October. In between annual tests, DTE Energy monitors its estimates and assumptions regarding estimated
future cash flows, including the impact of movements in market indicators in future quarters, and will update the impairment analyses if a triggering event occurs. While
DTE Energy believes the assumptions are reasonable, actual results may differ from projections. To the extent projected results or cash flows are revised downward, the
reporting unit may be required to write down all or a portion of its goodwill, which would adversely impact DTE Energy's earnings.
DTE Energy performed its annual impairment test as of October 1, 2024. In estimating fair value for the income approach, DTE Energy used discounted rates
ranging from 6.5% to 9.0%. Based on the weighting of the estimated fair value using an income and market approach, DTE Energy determined that the estimated fair
value of each reporting unit substantially exceeded its carrying value, and no impairment existed.
Long-Lived Assets
The Registrants evaluate the carrying value of long-lived assets, excluding goodwill, when circumstances indicate that the carrying value of those assets may not
be recoverable. Conditions that could have an adverse impact on the cash flows and fair value of the long-lived assets are deteriorating business climate, condition of the
asset, or plans to dispose of the asset before the end of its useful life. The review of long-lived assets for impairment requires significant assumptions about operating
strategies and estimates of future cash flows, which require assessments of current and projected market conditions. An impairment evaluation is based on an
undiscounted cash flow analysis at the lowest level for which independent cash flows of long-lived assets can be identified from other groups of assets and liabilities.
Impairment may occur when the carrying value of the asset exceeds the future undiscounted cash flows. When the undiscounted cash flow analysis indicates a long-
lived asset is not recoverable, the amount of the impairment loss is determined by measuring the excess of the long-lived asset over its fair value. An impairment would
require the Registrants to reduce both the long-lived asset and current period earnings by the amount of the impairment, which would adversely impact their earnings.
Pension and Other Postretirement Costs
DTE Energy sponsors both funded and unfunded defined benefit pension plans and other postretirement benefit plans for eligible employees of the Registrants.
The measurement of the plan obligations and cost of providing benefits under these plans involve various factors, including numerous assumptions and accounting
elections. When determining the various assumptions that are required, DTE Energy considers historical information as well as future expectations. The benefit costs are
affected by, among other things, the actual rate of return on plan assets, the long-term expected return on plan assets, the discount rate applied to benefit obligations, the
incidence of mortality, the expected remaining service period of plan participants, level of compensation and rate of compensation increases, employee age, length of
service, the anticipated rate of increase of health care costs, benefit plan design changes, and the level of benefits provided to employees and retirees. Pension and other
postretirement benefit costs attributed to the segments are included with labor costs and ultimately allocated to projects within the segments, some of which are
capitalized.
DTE Energy had pension credits of $18 million and $69 million in 2024 and 2023, respectively, and pension costs of $123 million in 2022. Other postretirement
benefit credits were $44 million in 2024, $38 million in 2023, and $66 million in 2022. Pension and other postretirement benefit credits for 2024 were calculated based
upon several actuarial assumptions, including an expected long-term rate of return on plan assets of 8.00% for the pension plans and 7.60% for the other postretirement
benefit plans. In developing the expected long-term rate of return assumptions, DTE Energy evaluated asset class risk and return expectations, as well as inflation
assumptions. Projected returns are based on broad equity, bond, and other markets. DTE Energy's 2025 expected long-term rate of return on pension plan assets is based
on an asset allocation assumption utilizing active and passive investment management of 15% in equity markets, 58% in fixed income markets - including long duration
bonds, and 27% invested in other assets. DTE Energy's 2025 expected long-term rate of return on other postretirement plan assets is based on an asset allocation
assumption utilizing active and passive investment management of 7% in equity markets, 63% in fixed income markets - including long duration bonds, and 30%
invested in other assets. Because of market volatility, DTE Energy periodically reviews the asset allocation and rebalances the portfolio when considered appropriate.
DTE Energy is decreasing its long-term rate of return assumption for the pension plans to 7.80% and decreasing the other postretirement plans to 7.50% for 2025. DTE
Energy believes these rates are reasonable assumptions for the long-term rates of return on the plans' assets for 2025 given their respective asset allocations and DTE
Energy's capital market expectations. DTE Energy will continue to evaluate the actuarial assumptions, including its expected rate of return, at least annually.

Table of Contents
DTE Energy calculates the expected return on pension and other postretirement benefit plan assets by multiplying the expected return on plan assets by the
market-related value (MRV) of plan assets at the beginning of the year, taking into consideration anticipated contributions and benefit payments that are to be made
during the year. Current accounting rules provide that the MRV of plan assets can be either fair value or a calculated value that recognizes changes in fair value in a
systematic and rational manner over not more than five years. For the pension plans, DTE Energy uses a calculated value when determining the MRV of the pension
plan assets and recognizes changes in fair value over a three-year period. Accordingly, the future value of assets will be impacted as previously deferred gains or losses
are recognized. As of December 31, 2024, DTE Energy had $131 million of cumulative losses related to investment performance in prior years that were not yet
recognized in the calculation of the MRV of pension assets. For other postretirement benefit plans, DTE Energy uses fair value when determining the MRV of plan
assets; therefore, all investment gains and losses have been recognized in the calculation of MRV for these plans.
The discount rate that DTE Energy utilizes for determining future pension and other postretirement benefit obligations is based on a yield curve approach and a
review of bonds that receive one of the two highest ratings given by a recognized rating agency. The yield curve approach matches projected pension plan and other
postretirement benefit payment streams with bond portfolios reflecting actual liability duration unique to the plans. The discount rate determined on this basis was
5.65% for the pension plans and 5.66% for the other postretirement plans at December 31, 2024 compared to 5.00% for both the pension and other postretirement plans
at December 31, 2023.
DTE Energy changed the mortality assumptions as of December 31,2024 to reflect recent plan experience. The mortality assumptions used at December 31, 2024
are the PRI-2012 mortality table projected using Scale MP-2021, with generational projection. The base mortality tables vary by type of plan, employee's union status
and employment status, with additional adjustments to reflect the actual experience and credibility of each population.
DTE Energy estimates a total pension cost of approximately $60 million for 2025, compared to the credit of $18 million in 2024. The expected change is primarily
related to the recognition of deferred investment losses. The 2025 other postretirement benefit credit is estimated at approximately $40 million, comparable to the credit
of $44 million in 2024.
The health care trend rates for DTE Energy assume 8.50% for pre-65 participants and 9.00% for post-65 participants for 2025, trending down to 4.50% for both
pre-65 and post-65 participants in 2035.
Future actual pension and other postretirement benefit costs or credits will depend on future investment performance, changes in future discount rates, and various
other factors related to plan design.
Lowering the expected long-term rate of return on the plan assets by one percentage point would have decreased the 2024 pension credit by approximately $43
million. Lowering the discount rate and the salary increase assumptions by one percentage point would have decreased the 2024 pension credit by approximately $18
million. Lowering the expected long-term rate of return on plan assets by one percentage point would have decreased the 2024 other postretirement credit by
approximately $16 million. Lowering the discount rate and the salary increase assumptions by one percentage point would have decreased the 2024 other postretirement
credit by approximately $7 million.
The value of the qualified pension and other postretirement benefit plan assets was $5.3 billion at December 31, 2024 and $5.6 billion at December 31, 2023. At
December 31, 2024, DTE Energy's qualified pension plans were underfunded by $115 million and its other postretirement benefit plans were over-funded by $471
million. In 2024, the funded status of the pension plans and other postretirement benefit plans improved primarily due to higher discount rates, along with updated
demographic assumptions that lowered the liability for the other postretirement benefit plans.
Pension and other postretirement costs and pension cash funding requirements may increase in future years without typical returns in the financial markets. Any
required pension funding will be made by contributing amounts consistent with the provisions of the Pension Protection Act of 2006. DTE Energy made a nominal
contribution to its qualified pension plans in 2024, no contribution in 2023, and does not anticipate making any material contributions in 2025. At the discretion of
management and depending on financial market conditions, DTE Gas anticipates transferring up to $25 million of qualified pension plan funds to DTE Electric annually
for the next five years in exchange for cash consideration. DTE Energy did not make other postretirement benefit plan contributions in 2024 or 2023 and does not
anticipate making any contributions to the other postretirement plans in 2025 or over the next five years. All planned contributions will be at the discretion of
management and subject to any changes in financial market conditions.

Table of Contents
Legal Reserves
The Registrants are involved in various legal proceedings, claims, and litigation arising in the ordinary course of business. The Registrants regularly assess their
liabilities and contingencies in connection with asserted or potential matters and establish reserves when appropriate. Legal reserves are based upon the Registrants'
management’s assessment of pending and threatened legal proceedings and claims against the Registrants.
Accounting for Tax Obligations
The Registrants are required to make judgments regarding the potential tax effects of various financial transactions and results of operations in order to estimate
their obligations to taxing authorities. The Registrants account for uncertain income tax positions using a benefit recognition model with a two-step approach, a more-
likely-than-not recognition criterion, and a measurement attribute that measures the position as the largest amount of tax benefit that is greater than 50% likely of being
realized upon ultimate settlement. If the benefit does not meet the more likely than not criteria for being sustained on its technical merits, no benefit will be recorded.
Uncertain tax positions that relate only to timing of when an item is included on a tax return are considered to have met the recognition threshold. The Registrants also
have non-income tax obligations related to property, sales and use, and employment-related taxes, and ongoing appeals related to these tax matters.
Accounting for tax obligations requires judgments, including assessing whether tax benefits are more likely than not to be sustained, and estimating reserves for
potential adverse outcomes regarding tax positions that have been taken. The Registrants also assess their ability to utilize tax attributes, including those in the form of
carry-forwards, for which the benefits have already been reflected in the Consolidated Financial Statements. The Registrants believe the resulting tax reserve balances as
of December 31, 2024 and 2023 are appropriate. The ultimate outcome of such matters could result in favorable or unfavorable adjustments to the Registrants'
Consolidated Financial Statements, and such adjustments could be material.
See Note 9 to the Consolidated Financial Statements, "Income Taxes."
NEW ACCOUNTING PRONOUNCEMENTS
See Note 3 to the Consolidated Financial Statements, "New Accounting Pronouncements."
FAIR VALUE
Derivatives are generally recorded at fair value and shown as Derivative assets or liabilities. Contracts DTE Energy typically classifies as derivative instruments
include power, natural gas, some environmental contracts, and certain forwards, futures, options and swaps, and foreign currency exchange contracts. Items DTE Energy
does not generally account for as derivatives include natural gas and environmental inventory, pipeline transportation contracts, storage assets, and some environmental
contracts. See Notes 11 and 12 to the Consolidated Financial Statements, "Fair Value" and "Financial and Other Derivative Instruments," respectively.
The tables below do not include the expected earnings impact of non-derivative natural gas storage, transportation, certain power contracts, and some
environmental contracts which are subject to accrual accounting. Consequently, gains and losses from these positions may not match with the related physical and
financial hedging instruments in some reporting periods, resulting in volatility in the Registrants' reported period-by-period earnings; however, the financial impact of
the timing differences will reverse at the time of physical delivery and/or settlement.
The Registrants manage their MTM risk on a portfolio basis based upon the delivery period of their contracts and the individual components of the risks within
each contract. Accordingly, the Registrants record and manage the energy purchase and sale obligations under their contracts in separate components based on the
commodity (e.g. electricity or natural gas), the product (e.g. electricity for delivery during peak or off-peak hours), the delivery location (e.g. by region), the risk profile
(e.g. forward or option), and the delivery period (e.g. by month and year).
The Registrants have established a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value in three broad levels. The fair
value hierarchy gives the highest priority to quoted prices (unadjusted) in active markets for identical assets or liabilities (Level 1) and the lowest priority to
unobservable inputs (Level 3). For further discussion of the fair value hierarchy, see Note 11 to the Consolidated Financial Statements, "Fair Value."

Item 7A. Quantitative and Qualitative Disclosures About Market Risk
Market Price Risk
The Electric and Gas businesses have commodity price risk, primarily related to the purchases of coal, natural gas, uranium, and electricity. However, the
Registrants do not bear significant exposure to earnings risk, as such changes are included in the PSCR and GCR regulatory rate-recovery mechanisms. Earnings may
be indirectly impacted if PSCR or GCR charges increase such that it impacts the collectability of receivables and increases uncollectible expense. Refer to the
Allowance for Doubtful Accounts section below for additional information.
Changes in the price of natural gas can also impact the valuation of lost and unaccounted for gas, storage sales, and transportation services revenue at the Gas
segment. The Gas segment manages its market price risk related to storage sales revenue primarily through the sale of long-term storage contracts. The Registrants are
exposed to short-term cash flow or liquidity risk as a result of the time differential between actual cash settlements and regulatory rate recovery.
The DTE Vantage segment is subject to price risk for electricity, natural gas, coal products, and environmental attributes generated from its renewable natural gas
investments. DTE Energy manages its exposure to commodity price risk through the use of long-term contracts and hedging instruments, when available.
DTE Energy's Energy Trading business segment has exposure to electricity, natural gas, environmental, crude oil, heating oil, and foreign currency exchange price
fluctuations. These risks are managed by the energy marketing and trading operations through the use of forward energy, capacity, storage, options, and futures
contracts, within predetermined risk parameters.

Table of Contents
Credit Risk
Allowance for Doubtful Accounts
The Registrants regularly review contingent matters, existing and future economic conditions, customer trends and other factors relating to customers and their
contracts and record provisions for amounts considered at risk of probable loss in the allowance for doubtful accounts. The Registrants believe their accrued amounts
are adequate for probable loss. The Registrants manage this risk by working at the state and federal levels to promote funding programs for low-income customers,
providing energy assistance programs and support, and promoting timely customer payments through adherence to MPSC billing practice rules relating to payment
arrangements, energy disconnects, and restores.
Trading Activities
DTE Energy is exposed to credit risk through trading activities. Credit risk is the potential loss that may result if the trading counterparties fail to meet their
contractual obligations. DTE Energy utilizes both external and internal credit assessments when determining the credit quality of trading counterparties.
The following table displays the credit quality of DTE Energy's trading counterparties as of December 31, 2024:

This category includes counterparties that have not been rated by Moody’s or Standard & Poor’s but are considered investment grade based on DTE Energy’s evaluation of the counterparty’s
creditworthiness. The five largest counterparty exposures, combined, for this category represented 11% of the total gross credit exposure.
(d)
This category includes counterparties that have not been rated by Moody’s or Standard & Poor’s and are considered non-investment grade based on DTE Energy’s evaluation of the counterparty’s
creditworthiness. The five largest counterparty exposures, combined, for this category represented less than 1% of the total gross credit exposure.
Other
The Registrants engage in business with customers that are non-investment grade. The Registrants closely monitor the credit ratings of these customers and, when
deemed necessary and permitted under the tariffs, request collateral or guarantees from such customers to secure their obligations.
Interest Rate Risk
DTE Energy is subject to interest rate risk in connection with the issuance of debt. In order to manage interest costs, DTE Energy may use treasury locks and
interest rate swap agreements. DTE Energy's exposure to interest rate risk arises primarily from changes in U.S. Treasury rates, commercial paper rates, credit spreads,
and SOFR. As of December 31, 2024, DTE Energy had floating rate debt of $1.1 billion and a floating rate debt-to-total debt ratio of 4.8%.

Table of Contents
Foreign Currency Exchange Risk
DTE Energy has foreign currency exchange risk arising from market price fluctuations associated with fixed priced contracts. These contracts are denominated in
Canadian dollars and are primarily for the purchase and sale of natural gas and power, as well as for long-term transportation capacity. To limit DTE Energy's exposure
to foreign currency exchange fluctuations, DTE Energy has entered into a series of foreign currency exchange forward contracts through December 2032.
Summary of Sensitivity Analyses
Sensitivity analyses were performed on the fair values of commodity contracts for DTE Energy and long-term debt obligations for the Registrants. The commodity
contracts listed below principally relate to energy marketing and trading activities. The sensitivity analyses involved increasing and decreasing forward prices and rates
at December 31, 2024 and 2023 by a hypothetical 10% and calculating the resulting change in the fair values. The hypothetical losses related to long-term debt would be
realized only if DTE Energy transferred all of its fixed-rate long-term debt to other creditors.

DTE Energy — Controls and Procedures
(a) Evaluation of disclosure controls and procedures
Management of DTE Energy carried out an evaluation, under the supervision and with the participation of DTE Energy's Chief Executive Officer (CEO) and Chief
Financial Officer (CFO), of the effectiveness of the design and operation of DTE Energy's disclosure controls and procedures (as defined in Exchange Act Rules 13a-
15(e) and 15d-15(e)) as of December 31, 2024, which is the end of the period covered by this report. Based on this evaluation, DTE Energy's CEO and CFO have
concluded that such disclosure controls and procedures are effective in providing reasonable assurance that information required to be disclosed by DTE Energy in
reports that it files or submits under the Exchange Act (i) is recorded, processed, summarized, and reported within the time periods specified in the U.S. Securities and
Exchange Commission's rules and forms and (ii) is accumulated and communicated to DTE Energy's management, including its CEO and CFO, as appropriate to allow
timely decisions regarding required disclosure. Due to the inherent limitations in the effectiveness of any disclosure controls and procedures, management cannot
provide absolute assurance that the objectives of its disclosure controls and procedures will be attained.
(b) Management’s report on internal control over financial reporting
Management of DTE Energy is responsible for establishing and maintaining adequate internal control over financial reporting as such term is defined in Exchange
Act Rules 13a-15(f) and 15d-15(f). Internal control over financial reporting is a process designed by, or under the supervision of, DTE Energy's CEO and CFO, to
provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with
generally accepted accounting principles.
Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of
effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the
policies or procedures may deteriorate.
Management of DTE Energy has assessed the effectiveness of DTE Energy’s internal control over financial reporting as of December 31, 2024. In making this
assessment, management used the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission (2013 COSO) in Internal Control -
Integrated Framework. Based on this assessment, management concluded that, as of December 31, 2024, DTE Energy’s internal control over financial reporting was
effective based on those criteria.
The effectiveness of DTE Energy's internal control over financial reporting as of December 31, 2024 has been audited by PricewaterhouseCoopers, LLP, an
independent registered public accounting firm who also audited DTE Energy's financial statements, as stated in their report which appears herein.
(c) Changes in internal control over financial reporting
There have been no changes in DTE Energy's internal control over financial reporting during the quarter ended December 31, 2024 that have materially affected,
or are reasonably likely to materially affect, DTE Energy's internal control over financial reporting.

Report of Independent Registered Public Accounting Firm
To the Board of Directors and Shareholders of DTE Energy Company
Opinions on the Financial Statements and Internal Control over Financial Reporting
We have audited the accompanying consolidated statements of financial position of DTE Energy Company and its subsidiaries (the “Company”) as of December 31,
2024 and 2023, and the related consolidated statements of operations, of comprehensive income, of changes in equity and of cash flows for each of the three years in the
period ended December 31, 2024, including the related notes (collectively referred to as the “consolidated financial statements”). We also have audited the Company's
internal control over financial reporting as of December 31, 2024, based on criteria established in Internal Control - Integrated Framework (2013) issued by the
Committee of Sponsoring Organizations of the Treadway Commission (COSO).
In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of the Company as of December 31,
2024 and 2023, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2024 in conformity with accounting
principles generally accepted in the United States of America. Also in our opinion, the Company maintained, in all material respects, effective internal control over
financial reporting as of December 31, 2024, based on criteria established in Internal Control - Integrated Framework (2013) issued by the COSO.
Basis for Opinions
The Company's management is responsible for these consolidated financial statements, for maintaining effective internal control over financial reporting, and for its
assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management’s report on internal control over financial
reporting. Our responsibility is to express opinions on the Company’s consolidated financial statements and on the Company's internal control over financial reporting
based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be
independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange
Commission and the PCAOB.
We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audits to obtain reasonable assurance
about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud, and whether effective internal control over financial
reporting was maintained in all material respects.
Our audits of the consolidated financial statements included performing procedures to assess the risks of material misstatement of the consolidated financial statements,
whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the
amounts and disclosures in the consolidated financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by
management, as well as evaluating the overall presentation of the consolidated financial statements. Our audit of internal control over financial reporting included
obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and
operating effectiveness of internal control based on the assessed risk. Our audits also included performing such other procedures as we considered necessary in the
circumstances. We believe that our audits provide a reasonable basis for our opinions.
Definition and Limitations of Internal Control over Financial Reporting
A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the
preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial
reporting includes those policies and procedures that (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and
dispositions of the assets of the company; (ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in
accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of
management and directors of the company; and (iii) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or
disposition of the company’s assets that could have a material effect on the financial statements.
54

Table of Contents
Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness
to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or
procedures may deteriorate.
Critical Audit Matters
The critical audit matter communicated below is a matter arising from the current period audit of the consolidated financial statements that was communicated or
required to be communicated to the audit committee and that (i) relates to accounts or disclosures that are material to the consolidated financial statements and (ii)
involved our especially challenging, subjective, or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the
consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate opinion on the critical audit
matter or on the accounts or disclosures to which it relates.
Accounting for the Effects of New, or Changes to Existing, Regulatory Matters
As described in Note 8 to the consolidated financial statements, the Company recorded $7,511 million of regulatory assets and $3,037 million of regulatory liabilities as
of December 31, 2024. The Company is required to record regulatory assets and liabilities for certain transactions that would have been treated as revenue or expense in
non-regulated businesses. Continued applicability of regulatory accounting treatment requires that rates be designed to recover specific costs of providing regulatory
services and be charged to and collected from customers. Future regulatory changes could result in a discontinuance of this accounting treatment for regulatory assets
and liabilities for some or all of the Company’s regulated businesses and may require the write-off of the portion of any regulatory asset or liability that was no longer
probable of recovery through regulated rates. Management believes that currently available facts support the continued use of regulatory assets and liabilities and that all
regulatory assets and liabilities are recoverable or refundable in the current regulatory environment.
The principal considerations for our determination that performing procedures relating to accounting for the effects of new, or changes to existing, regulatory matters is
a critical audit matter are (i) the significant judgment by management in assessing the potential outcomes and related accounting impacts associated with new, or
changes to existing, regulatory matters and (ii) a high degree of auditor judgment, subjectivity and effort in performing procedures and evaluating the appropriateness of
management’s assessment and audit evidence related to the assessment.
Addressing the matter involved performing procedures and evaluating audit evidence in connection with forming our overall opinion on the consolidated financial
statements. These procedures included testing the effectiveness of controls relating to management’s assessment and implementation of new regulatory matters or
changes to existing regulatory matters. These procedures also included, among others, (i) evaluating the reasonableness of management’s assessment of impacts arising
from correspondence with regulators and changes in laws and regulations; (ii) evaluating the sufficiency of the disclosures in the consolidated financial statements; and
(iii) testing, on a sample basis, the regulatory assets and liabilities, including those subject to pending rate orders and regulatory proceedings, by considering (a) the
provisions and formulas outlined in rate orders; (b) other regulatory correspondence; and (c) application of relevant regulatory precedents.

DTE Electric — Controls and Procedures
(a) Evaluation of disclosure controls and procedures
Management of DTE Electric carried out an evaluation, under the supervision and with the participation of DTE Electric's Chief Executive Officer (CEO) and
Chief Financial Officer (CFO), of the effectiveness of the design and operation of DTE Electric's disclosure controls and procedures (as defined in Exchange Act Rules
13a-15(e) and 15d-15(e)) as of December 31, 2024, which is the end of the period covered by this report. Based on this evaluation, DTE Electric's CEO and CFO have
concluded that such disclosure controls and procedures are effective in providing reasonable assurance that information required to be disclosed by DTE Electric in
reports that it files or submits under the Exchange Act (i) is recorded, processed, summarized, and reported within the time periods specified in the U.S. Securities and
Exchange Commission's rules and forms and (ii) is accumulated and communicated to DTE Electric's management, including its CEO and CFO, as appropriate to allow
timely decisions regarding required disclosure. Due to the inherent limitations in the effectiveness of any disclosure controls and procedures, management cannot
provide absolute assurance that the objectives of its disclosure controls and procedures will be attained.
(b) Management’s report on internal control over financial reporting
Management of DTE Electric is responsible for establishing and maintaining adequate internal control over financial reporting as such term is defined in Exchange
Act Rules 13a-15(f) and 15d-15(f). Internal control over financial reporting is a process designed by, or under the supervision of, DTE Electric's CEO and CFO, to
provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with
generally accepted accounting principles.
Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of
effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the
policies or procedures may deteriorate.
Management of DTE Electric has assessed the effectiveness of DTE Electric's internal control over financial reporting as of December 31, 2024. In making this
assessment, management used the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission (2013 COSO) in Internal Control -
Integrated Framework. Based on this assessment, management concluded that, as of December 31, 2024, DTE Electric's internal control over financial reporting was
effective based on those criteria.
This annual report does not include an audit report of DTE Electric's independent registered public accounting firm regarding internal control over financial
reporting. Management’s report was not subject to audit by DTE Electric's independent registered public accounting firm pursuant to rules of the Securities and
Exchange Commission that permit DTE Electric to provide only management’s report in this annual report.
(c) Changes in internal control over financial reporting
There have been no changes in DTE Electric's internal control over financial reporting during the quarter ended December 31, 2024 that have materially affected,
or are reasonably likely to materially affect, DTE Electric's internal control over financial reporting.

Report of Independent Registered Public Accounting Firm
To the Board of Directors and Shareholder of DTE Electric Company
Opinion on the Financial Statements
We have audited the accompanying consolidated statements of financial position of DTE Electric Company and its subsidiaries (the “Company”) as of December 31,
2024 and 2023, and the related consolidated statements of operations, of comprehensive income, of changes in shareholder’s equity and of cash flows for each of the
three years in the period ended December 31, 2024, including the related notes (collectively referred to as the “consolidated financial statements”). In our opinion, the
consolidated financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2024 and 2023, and the results of its
operations and its cash flows for each of the three years in the period ended December 31, 2024 in conformity with accounting principles generally accepted in the
United States of America.
Basis for Opinion
These consolidated financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on the Company’s consolidated
financial statements based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB)
and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the
Securities and Exchange Commission and the PCAOB.
We conducted our audits of these consolidated financial statements in accordance with the standards of the PCAOB. Those standards require that we plan and perform
the audits to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud. The
Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audits we are required to obtain
an understanding of internal control over financial reporting but not for the purpose of expressing an opinion on the effectiveness of the Company's internal control over
financial reporting. Accordingly, we express no such opinion.
Our audits included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due to error or fraud, and
performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the
consolidated financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as
evaluating the overall presentation of the consolidated financial statements. We believe that our audits provide a reasonable basis for our opinion.
Critical Audit Matters
The critical audit matter communicated below is a matter arising from the current period audit of the consolidated financial statements that was communicated or
required to be communicated to the audit committee and that (i) relates to accounts or disclosures that are material to the consolidated financial statements and (ii)
involved our especially challenging, subjective, or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the
consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate opinion on the critical audit
matter or on the accounts or disclosures to which it relates.
Accounting for the Effects of New, or Changes to Existing, Regulatory Matters
As described in Note 8 to the consolidated financial statements, the Company recorded $6,916 million of regulatory assets and $1,909 million of regulatory liabilities as
of December 31, 2024. The Company is required to record regulatory assets and liabilities for certain transactions that would have been treated as revenue or expense in
non-regulated businesses. Continued applicability of regulatory accounting treatment requires that rates be designed to recover specific costs of providing regulatory
services and be charged to and collected from customers. Future regulatory changes could result in a discontinuance of this accounting treatment for regulatory assets
and liabilities for some or all of the Company’s regulated businesses and may require the write-off of the portion of any regulatory asset or liability that was no longer
probable of recovery through regulated rates. Management believes that currently available facts support the continued use of regulatory assets and liabilities and that all
regulatory assets and liabilities are recoverable or refundable in the current regulatory environment.
64

Table of Contents
The principal considerations for our determination that performing procedures relating to accounting for the effects of new, or changes to existing, regulatory matters is
a critical audit matter are (i) the significant judgment by management in assessing the potential outcomes and related accounting impacts associated with new, or
changes to existing, regulatory matters and (ii) a high degree of auditor judgment, subjectivity and effort in performing procedures and evaluating the appropriateness of
management’s assessment and audit evidence related to the assessment.
Addressing the matter involved performing procedures and evaluating audit evidence in connection with forming our overall opinion on the consolidated financial
statements. These procedures included testing the effectiveness of controls relating to management’s assessment and implementation of new regulatory matters or
changes to existing regulatory matters. These procedures also included, among others, (i) evaluating the reasonableness of management’s assessment of impacts arising
from correspondence with regulators and changes in laws and regulations; (ii) evaluating the sufficiency of the disclosures in the consolidated financial statements; and
(iii) testing, on a sample basis, the regulatory assets and liabilities, including those subject to pending rate orders and regulatory proceedings, by considering (a) the
provisions and formulas outlined in rate orders; (b) other regulatory correspondence; and (c) application of relevant regulatory precedents.

Combined Notes to Consolidated Financial Statements — (Continued)
Basis of Presentation
The accompanying Consolidated Financial Statements of the Registrants are prepared using accounting principles generally accepted in the United States of
America. These accounting principles require management to use estimates and assumptions that impact reported amounts of assets, liabilities, revenues and expenses,
and the disclosure of contingent assets and liabilities. Actual results may differ from the Registrants' estimates.
The information in these combined notes relates to each of the Registrants as noted in the Index of Combined Notes to Consolidated Financial Statements.
However, DTE Electric does not make any representation as to information related solely to DTE Energy or the subsidiaries of DTE Energy other than itself.
Certain prior year balances for the Registrants were reclassified to match the current year's Consolidated Financial Statements presentation.
Principles of Consolidation
The Registrants consolidate all majority-owned subsidiaries and investments in entities in which they have controlling influence. Non-majority owned investments
are accounted for using the equity method when the Registrants are able to significantly influence the operating policies of the investee. When the Registrants do not
influence the operating policies of an investee, the equity investment is valued at cost minus any impairments, if applicable. These Consolidated Financial Statements
also reflect the Registrants' proportionate interests in certain jointly-owned utility plants. The Registrants eliminate all intercompany balances and transactions.
The Registrants evaluate whether an entity is a VIE whenever reconsideration events occur. The Registrants consolidate VIEs for which they are the primary
beneficiary. If a Registrant is not the primary beneficiary and an ownership interest is held, the VIE is accounted for under the equity method of accounting. When
assessing the determination of the primary beneficiary, a Registrant considers all relevant facts and circumstances, including: the power, through voting or similar rights,
to direct the activities of the VIE that most significantly impact the VIE's economic performance and the obligation to absorb the expected losses and/or the right to
receive the expected returns of the VIE. The Registrants perform ongoing reassessments of all VIEs to determine if the primary beneficiary status has changed.
Legal entities within the DTE Vantage segment enter into long-term contractual arrangements with customers to supply energy-related products or services. The
entities are generally designed to pass-through the commodity risk associated with these contracts to the customers, with DTE Energy retaining operational and
customer default risk. These entities generally are VIEs and consolidated when DTE Energy is the primary beneficiary. In addition, DTE Energy has interests in certain
VIEs through which control of all significant activities is shared with partners, and therefore are generally accounted for under the equity method.
The Registrants hold ownership interests in certain limited partnerships. The limited partnerships include investment funds which support regional development
and economic growth, and an operational business providing energy-related products. These entities are generally VIEs as a result of certain characteristics of the
limited partnership voting rights. The ownership interests are accounted for under the equity method as the Registrants are not the primary beneficiaries.
DTE Energy has variable interests in VIEs through certain of its long-term purchase and sale contracts. DTE Electric has variable interests in VIEs through certain
of its long-term purchase contracts. As of December 31, 2024, the carrying amount of assets and liabilities in DTE Energy's Consolidated Statements of Financial
Position that relate to its variable interests under long-term purchase and sale contracts are predominantly related to working capital accounts and generally represent the
amounts owed by or to DTE Energy for the deliveries associated with the current billing cycle under the contracts. As of December 31, 2024, the carrying amount of
assets and liabilities in DTE Electric's Consolidated Statements of Financial Position that relate to its variable interests under long-term purchase contracts are
predominantly related to working capital accounts and generally represent the amounts owed by DTE Electric for the deliveries associated with the current billing cycle
under the contracts. The Registrants have not provided any significant form of financial support associated with these long-term contracts. There is no material potential
exposure to loss as a result of DTE Energy's variable interests through these long-term purchase and sale contracts. In addition, there is no material potential exposure to
loss as a result of DTE Electric's variable interests through these long-term purchase contracts.

DTE Energy Company — DTE Electric Company
Combined Notes to Consolidated Financial Statements — (Continued)
DTE Electric previously financed regulatory assets for deferred costs related to certain retired generation plants and its tree trimming surge program through the
sale of bonds by wholly-owned special purpose entities, DTE Securitization I and DTE Securitization II (collectively "the DTE Securitization entities"). The DTE
Securitization entities are VIEs. DTE Electric has the power to direct the most significant activities of these entities, including performing servicing activities such as
billing and collecting surcharge revenue. Accordingly, DTE Electric is the primary beneficiary and the DTE Securitization entities are consolidated by the Registrants.
Securitization bond holders have no recourse to the Registrants' assets, except for those held by the DTE Securitization entities. Surcharges collected by DTE Electric to
pay for bond servicing and other qualified costs reflect securitization property solely owned by the DTE Securitization entities. These surcharges are remitted to a
trustee and are not available to other creditors of the Registrants.
The maximum risk exposure for consolidated VIEs is reflected on the Registrants' Consolidated Statements of Financial Position. For non-consolidated VIEs, the
maximum risk exposure of the Registrants is generally limited to their investment and notes receivable.
The table below summarizes the major Consolidated Statements of Financial Position items for consolidated VIEs as of December 31, 2024 and 2023. All assets
and liabilities of a consolidated VIE are presented where it has been determined that a consolidated VIE has either (1) assets that can be used only to settle obligations of
the VIE or (2) liabilities for which creditors do not have recourse to the general credit of the primary beneficiary. Assets and liabilities of the DTE Securitization entities
have been aggregated due to their similar nature and are separately stated in the table below, comprising the entirety of the DTE Electric amounts. For all other VIEs,
assets and liabilities are also aggregated due to their similar nature and presented together with the DTE Securitization entities in the DTE Energy amounts below. VIEs,
in which DTE Energy holds a majority voting interest and is the primary beneficiary, that meet the definition of a business and whose assets can be used for purposes
other than the settlement of the VIE's obligations have been excluded from the table.
Amounts for the Registrants' consolidated VIEs are as follows:

Equity Method Investments
Investments in non-consolidated affiliates that are not controlled by the Registrants, but over which they have significant influence, are accounted for using the
equity method. Certain of the equity method investees are also considered VIEs and disclosed in the non-consolidated VIEs table above.
At December 31, 2024 and 2023, DTE Energy's Investments in equity method investees were $128 million and $166 million, respectively. The balances are
primarily comprised of investments in the DTE Vantage segment and Corporate and Other, of which no investment is individually significant. DTE Vantage investments
include projects that deliver energy and utility-type products and services to industrial customers, sell electricity and gas from renewable energy projects, and produce
and sell metallurgical coke. Corporate and Other holds various ownership interests in limited partnerships that include investment funds supporting regional
development and economic growth. For further information by segment, see Note 21 to the Consolidated Financial Statements, "Segment and Related Information."
At December 31, 2024 and 2023, DTE Energy's share of the underlying equity in the net assets of the investees exceeded the carrying amounts of Investments in
equity method investees by $94 million and $101 million, respectively. The difference is being amortized over the life of the underlying assets.
NOTE 2 — SIGNIFICANT ACCOUNTING POLICIES

Information."
Accounting for ISO Transactions
DTE Electric participates in the energy market through MISO. MISO requires that DTE Electric submit hourly day-ahead, real-time, and FTR bids and offers for
energy at locations across the MISO region. DTE Electric accounts for MISO transactions on a net hourly basis in each of the day-ahead, real-time, and FTR markets. In
any single hour, transactions in each of the MISO energy markets are netted based on MWh to determine if DTE Electric is in a net sale or purchase position. Net
purchases are recorded in Fuel, purchased power, and gas — utility and net sales are recorded in Operating Revenues — Utility operations on the Registrants'
Consolidated Statements of Operations.
The Energy Trading segment participates in the energy markets through various ISOs and RTOs. These markets require that Energy Trading submits hourly day-
ahead, real-time bids and offers for energy at locations across each region. Energy Trading submits bids in the annual and monthly auction revenue rights and FTR
auctions to the RTOs. Energy Trading accounts for these transactions on a net hourly basis for the day-ahead, real-time, and FTR markets. These transactions are related
to trading contracts which, if derivatives, are presented on a net basis in Operating Revenues — Non-utility operations, and if non-derivatives, the realized gains and
losses for sales are recorded in Operating Revenues — Non-utility operations and purchases are recorded in Fuel, purchased power, gas, and other — non-utility in the
DTE Energy Consolidated Statements of Operations.
DTE Electric and Energy Trading record accruals for future net purchase adjustments based on historical experience and reconcile accruals to actual costs when
invoices are received from MISO and other ISOs and RTOs.
Derivatives
Energy Trading classifies derivative transactions as revenue or expense based on the intent of the transaction (buy or sell). Revenues are recorded on a gross or net
basis within the income statement depending upon whether it represents a non-trading activity or trading activity, respectively. Cash flows associated with derivative
instruments, including related gains and losses, are presented as Operating Activities within the Registrants' Consolidated Statements of Cash Flows. For additional
information, refer to Note 12 to the Consolidated Financial Statements, "Financial and Other Derivative Instruments."
Changes in Accumulated Other Comprehensive Income (Loss)
Comprehensive income (loss) is the change in common shareholders’ equity during a period from transactions and events from non-owner sources, including Net
Income. The amounts recorded to Accumulated other comprehensive income (loss) for DTE Energy include changes in benefit obligations, consisting of deferred
actuarial losses and prior service costs, unrealized gains and losses from derivatives accounted for as cash flow hedges, and foreign currency translation adjustments, if
any. DTE Energy releases income tax effects from accumulated other comprehensive income when the circumstances upon which they are premised cease to exist.
Changes in Accumulated other comprehensive income (loss) are presented in DTE Energy's Consolidated Statements of Changes in Equity and DTE Electric's

Benefit obligations activity includes changes in actuarial (gain) loss and prior service cost in DTE Energy's pension and other postretirement benefit plans. Refer to Note 19 to the Consolidated Financial
Statements, "Retirement Benefits and Trusteed Assets," for details regarding this activity.
Cash, Cash Equivalents, and Restricted Cash
Cash and cash equivalents include cash on hand, cash in banks, and temporary investments purchased with maturities of three months or less. Restricted cash
includes funds held in separate bank accounts and principally consists of amounts at DTE Securitization I and DTE Securitization II to pay for debt service and other
qualified costs. Restricted cash also consists of funds held to satisfy contractual obligations related to a large construction project at DTE Vantage. Restricted cash
designated for payments within one year is classified as a Current Asset.
Financing Receivables
Financing receivables are primarily composed of trade receivables, notes receivable, and unbilled revenue. The Registrants' financing receivables are stated at net
realizable value.
DTE Energy had unbilled revenues of $992 million and $882 million at December 31, 2024 and 2023, respectively, including $303 million and $311 million of
DTE Electric unbilled revenues, respectively, included in Customer Accounts receivable.
The Registrants monitor the credit quality of their financing receivables on a regular basis by reviewing credit quality indicators and monitoring for trigger events,
such as a credit rating downgrade or bankruptcy. Credit quality indicators include, but are not limited to, ratings by credit agencies where available, collection history,
collateral, counterparty financial statements and other internal metrics. Utilizing such data, the Registrants have determined three internal grades of credit quality.
Internal grade 1 includes financing receivables for counterparties where credit rating agencies have ranked the counterparty as investment grade. To the extent credit
ratings are not available, the Registrants utilize other credit quality indicators to determine the level of risk associated with the financing receivable. Internal grade 1
may include financing receivables for counterparties for which credit rating agencies have ranked the counterparty as below investment grade; however, due to
favorable information on other credit quality indicators, the Registrants have determined the risk level to be similar to that of an investment grade counterparty. Internal
grade 2 includes financing receivables for counterparties with limited credit information and those with a higher risk profile based upon credit quality indicators.
Internal grade 3 reflects financing receivables for which the counterparties have the greatest level of risk, including those in bankruptcy status.

For DTE Energy, the current portion is included in Current Assets — Other on the Consolidated Statements of Financial Position. For DTE Electric, the amounts are included in Other Assets — Other on
the Consolidated Statements of Financial Position.
The allowance for doubtful accounts on accounts receivable for the utility entities is generally calculated using an aging approach that utilizes rates developed in
reserve studies. DTE Electric and DTE Gas establish an allowance for uncollectible accounts based on historical losses and management's assessment of existing and
future economic conditions, customer trends and other factors. Customer accounts are generally considered delinquent if the amount billed is not received by the due
date, which is typically in 21 days, however, factors such as assistance programs may delay aggressive action. DTE Electric and DTE Gas generally assess late payment
fees on trade receivables based on past-due terms with customers. Customer accounts are written off when collection efforts have been exhausted. The time period for
write-off is 150 days after service has been terminated.
The customer allowance for doubtful accounts for non-utility businesses and other receivables for both utility and non-utility businesses is generally calculated
based on specific review of probable future collections based on receivable balances generally in excess of 30 days. Existing and future economic conditions, customer
trends and other factors are also considered. Receivables are written off on a specific identification basis and determined based upon the specific circumstances of the
associated receivable.
Notes receivable for DTE Energy are primarily comprised of finance lease receivables and loans that are included in Notes Receivable and Other current assets on
DTE Energy's Consolidated Statements of Financial Position. Notes receivable for DTE Electric are primarily comprised of loans.
The Registrants establish an allowance for credit loss for principal and interest amounts due that are estimated to be uncollectible in accordance with the
contractual terms of the note receivable. In determining the allowance for credit losses for notes receivable, the Registrants consider the historical payment experience
and other factors that are expected to have a specific impact on the counterparty's ability to pay including existing and future economic conditions. Notes receivable are
typically considered delinquent when payment is not received for periods ranging from 60 to 120 days. If amounts are no longer probable of collection, the Registrants
may consider the note receivable impaired, adjust the allowance, and cease accruing interest (nonaccrual status).
Cash payments received on nonaccrual status notes receivable, that do not bring the account contractually current, are first applied to the contractually owed past
due interest, with any remainder applied to principal. Accrual of interest is generally resumed when the note receivable becomes contractually current.

There are no material amounts of past due financing receivables for the Registrants as of December 31, 2024.
Inventories
Inventory related to utility and non-utility operations is valued at the lower of cost or net realizable value, where cost is generally valued using average cost.
Inventory primarily includes fuel, gas, materials, and supplies. Other inventories include RECs, emission allowances, and other environmental products in the Energy
Trading segment.
DTE Gas' natural gas inventory includes $69 million and $73 million as of December 31, 2024 and 2023, respectively, that is determined using the last-in, first-out
(LIFO) method. The replacement cost of gas in inventory exceeded the LIFO cost by $81 million and $50 million at December 31, 2024 and 2023, respectively.
Property, Retirement and Maintenance, and Depreciation and Amortization
Property is stated at cost and includes construction-related labor, materials, overheads, and AFUDC for utility property. The cost of utility properties retired is
charged to accumulated depreciation. Expenditures for maintenance and repairs are charged to expense when incurred.
Utility property at DTE Electric and DTE Gas is depreciated over its estimated useful life using straight-line rates approved by the MPSC. DTE Energy's non-
utility property is depreciated over its estimated useful life using the straight-line method. Depreciation and amortization expense also includes the amortization of
certain regulatory assets and liabilities for the Registrants.
The cost of nuclear fuel is capitalized. The amortization of nuclear fuel is included within Fuel, purchased power, and gas — utility in the DTE Energy
Consolidated Statements of Operations, and Fuel and purchased power in the DTE Electric Consolidated Statements of Operations, and is recorded using the units-of-
production method.

Long-Lived Assets
Long-lived assets are reviewed for impairment whenever events or changes in circumstances indicate the carrying amount of an asset may not be recoverable. If
the carrying amount of the asset exceeds the expected undiscounted future cash flows generated by the asset, an impairment loss is recognized resulting in the asset
being written down to its estimated fair value. Assets to be disposed of are reported at the lower of the carrying amount or fair value, less costs to sell.
Goodwill
DTE Energy has goodwill resulting from business combinations. For each reporting unit, DTE Energy performs an impairment test annually or whenever events or
circumstances indicate that the value of goodwill may be impaired. For the years ended December 31, 2024 and 2023, there were no impairments resulting from these
tests and there were no other changes in the carrying amount of goodwill.

Cloud Computing Arrangements
The Registrants capitalize implementation costs incurred in a cloud computing arrangement that is a service contract consistent with capitalized implementation
costs incurred to develop or obtain internal-use software. Capitalized costs are recorded in Other noncurrent assets on the Consolidated Statements of Financial Position
and amortization of the costs is reflected in Operation and maintenance within the Consolidated Statements of Operations. Costs are amortized on a straight-line basis
over the life of the contract. Contracts primarily involve the implementation or upgrade of cloud-based solutions for generation and distribution operations and customer
service support.

Excise and Sales Taxes
The Registrants record the billing of excise and sales taxes as a receivable with an offsetting payable to the applicable taxing authority, with no net impact on the
Registrants’ Consolidated Statements of Operations.
Deferred Debt Costs
The costs related to the issuance of long-term debt are deferred and amortized over the life of each debt issue. The deferred amounts are included as a direct
deduction from the carrying amount of each debt issue in Mortgage bonds, notes, and other and Securitization bonds on the Registrants' Consolidated Statements of
Financial Position and in Junior subordinated debentures on DTE Energy's Consolidated Statements of Financial Position. In accordance with MPSC regulations
applicable to DTE Energy’s electric and gas utilities, the unamortized discount, premium, and expense related to utility debt redeemed with a refinancing are amortized
over the life of the replacement issue. Discounts, premiums, and expense on early redemptions of debt associated with DTE Energy's non-utility operations are charged
to earnings.
Investments in Debt and Equity Securities
The Registrants generally record investments in debt and equity securities at market value with unrealized gains or losses included in earnings. Changes in the fair
value of Fermi 2 nuclear decommissioning investments are recorded as adjustments to Regulatory assets or liabilities, due to a recovery mechanism from customers.
The Registrants' equity investments are reviewed for impairment each reporting period. If the assessment indicates that an impairment exists, a loss is recognized
resulting in the equity investment being written down to its estimated fair value. See Note 11 of the Consolidated Financial Statements, "Fair Value."
DTE Energy Foundation
DTE Energy made a charitable contribution to the DTE Energy Foundation of $10 million for the year ended December 31, 2024. There were no contributions for
the years ended December 31, 2023 and 2022. The DTE Energy Foundation is a non-consolidated not-for-profit private foundation, the purpose of which is to contribute
to and assist charitable organizations.

NOTE 4 — REVENUE
Significant Accounting Policy
Revenue is measured based upon the consideration specified in a contract with a customer at the time when performance obligations are satisfied. A performance
obligation is a promise in a contract to transfer a distinct good or service or a series of distinct goods or services to the customer. The Registrants recognize revenue
when performance obligations are satisfied by transferring control over a product or service to a customer. The Registrants have determined control to be transferred
when the product is delivered, or the service is provided to the customer.
Rates for DTE Electric and DTE Gas include provisions to adjust billings for fluctuations in fuel and purchased power costs, cost of natural gas, and certain other
costs. Revenues are adjusted for differences between actual costs subject to reconciliation and the amounts billed in current rates. Under or over recovered revenues
related to these cost recovery mechanisms are included in Regulatory assets or liabilities on the Registrants' Consolidated Statements of Financial Position and are
recovered or returned to customers through adjustments to the billing factors.
For discussion of derivative contracts, see Note 12 to the Consolidated Financial Statements, "Financial and Other Derivative Instruments."

Nature of Goods and Services
The following is a description of principal activities, separated by reportable segments, from which DTE Energy generates revenue. For more detailed information
about reportable segments, see Note 21 to the Consolidated Financial Statements, “Segment and Related Information.”
The Registrants have contracts with customers which may contain more than one performance obligation. When more than one performance obligation exists in a
contract, the consideration under the contract is allocated to the performance obligations based on the relative standalone selling price. DTE Energy generally
determines standalone selling prices based on the prices charged to customers or the use of the adjusted market assessment approach. The adjusted market assessment
approach involves the evaluation of the market in which DTE Energy sells goods or services and estimating the price that a customer in that market would be willing to
pay.
Under Topic 606, when a customer simultaneously receives and consumes the product or service provided, revenue is considered to be recognized over time.
Alternatively, if it is determined that the criteria for recognition of revenue over time is not met, the revenue is considered to be recognized at a point in time.
Electric segment
The Electric segment consists principally of DTE Electric. Electric revenues are primarily comprised of the supply and delivery of electricity, related capacity, and
RECs. Revenues are primarily associated with cancellable contracts, with the exception of certain long-term contracts with commercial and industrial customers.
Revenues, including estimated unbilled amounts, are generally recognized over time based upon volumes delivered or through the passage of time ratably based upon
providing a stand-ready service. The Registrants have determined that the above methods represent a faithful depiction of the transfer of control to the customer.
Unbilled revenues are typically determined utilizing approved tariff rates and estimated meter volumes. Estimated unbilled amounts recognized in revenue are subject to
adjustment in the following reporting period as actual volumes by customer class are known. Revenues are typically subject to tariff rates based upon customer class and
type of service and are billed and received monthly. Tariff rates are determined by the MPSC on a per unit or monthly basis.
Gas segment
The Gas segment consists principally of DTE Gas. Gas revenues are primarily comprised of the supply and delivery of natural gas, and other services including
storage, transportation, and appliance maintenance. Revenues are primarily associated with cancellable contracts, with the exception of certain long-term contracts with
commercial and industrial customers. Revenues, including estimated unbilled amounts, are generally recognized over time based upon volumes delivered or through the
passage of time ratably based upon providing a stand-ready service. DTE Energy has determined that the above methods represent a faithful depiction of the transfer of
control to the customer. Unbilled revenues are typically determined using both estimated meter volumes and estimated usage based upon the number of unbilled days
and historical temperatures. Estimated unbilled amounts recognized in revenue are subject to adjustment in the following reporting period as actual volumes by
customer class and service type are known. Revenues are typically subject to tariff rates or other rates subject to regulatory oversight and are billed and received
monthly. Tariff rates are determined by the MPSC on a per unit or monthly basis.
DTE Vantage segment
The DTE Vantage segment revenues include contracts accounted for as leases which are outside of the scope of Topic 606. For performance obligations within the
scope of Topic 606, the timing of revenue recognition is dependent upon when control over the associated product or service is transferred.

DTE Energy Company — DTE Electric Company
Combined Notes to Consolidated Financial Statements — (Continued)
Revenues at DTE Vantage, within the scope of Topic 606, generally consist of sales of blast furnace coke, renewable natural gas and related credits, electricity,
equipment maintenance services, and other energy related products and services. Revenues for the sale of blast furnace coke, including estimated unbilled amounts, are
recognized at a point in time when the product is delivered, which represents the transfer of control to the customer. Other revenues are generally recognized over time
based upon volumes delivered or services provided, or through the passage of time ratably based upon providing a stand-ready service. DTE Energy has determined that
the above methods represent a faithful depiction of the transfer of control to the customer. Market based pricing structures exist in such contracts including adjustments
for consumer price or other indices. Consideration may consist of both fixed and variable components. Generally, uncertainties in the variable consideration components
are resolved, and revenues are known at the time of recognition. Billing terms vary and are generally monthly with payment terms typically within 30 days following
billing.
Energy Trading segment
The Energy Trading segment revenues consist primarily of derivative contracts outside of the scope of Topic 606. For performance obligations within the scope of
Topic 606, the timing of revenue recognition is dependent upon when control over the associated product or service is transferred.
Revenues, including estimated unbilled amounts, within the scope of Topic 606 arising from the sale of natural gas, electricity, power capacity, and other energy
related products are generally recognized over time based upon volumes delivered or through the passage of time ratably based upon providing a stand-ready service.
DTE Energy has determined that the above methods represent a faithful depiction of the transfer of control to the customer. Revenues are known at the time of
recognition. Payment for the aforementioned revenues is generally due from customers in the month following delivery.
Revenues associated with RECs and other environmental products are recognized at a point in time when control is transferred to the customer which is deemed to
be when these products are entered for transfer to the customer in the applicable tracking system. Revenues associated with RECs under a wholesale full requirements
power contract are deferred until control has been transferred. The deferred revenues represent a contract liability for which payment has been received and the amounts
have been estimated using the adjusted market assessment approach. With the exception of RECs, generally all other performance obligations associated with wholesale
full requirements power contracts are satisfied over time in conjunction with the delivery of power. At the time power is delivered, DTE Energy may not have control
over the RECs as the RECs are not self-generated and may not yet have been procured resulting in deferred revenues.

Deferred revenues are included in Current Liabilities — Other and Other Liabilities — Other on DTE Energy's Consolidated Statements of Financial Position.
Deferred revenues generally represent amounts paid by or receivables from customers for which the associated performance obligation has not yet been satisfied.
Deferred revenues include amounts associated with REC performance obligations under certain wholesale full requirements power contracts. Deferred revenues related
to RECs are recognized as revenue when control of the RECs has transferred. Other performance obligations associated with deferred revenues include providing
products and services related to customer prepayments. Deferred revenues associated with these products and services are recognized when control has transferred to the
customer.

Transaction Price Allocated to the Remaining Performance Obligations
In accordance with optional exemptions available under Topic 606, the Registrants did not disclose the value of unsatisfied performance obligations for (1)
contracts with an original expected length of one year or less, (2) with the exception of fixed consideration, contracts for which revenue is recognized at the amount to
which the Registrants have the right to invoice for goods provided and services performed, and (3) contracts for which variable consideration relates entirely to an
unsatisfied performance obligation.
Such contracts consist of varying types of performance obligations across the segments, including the supply and delivery of energy related products and services.
Contracts with variable volumes and/or variable pricing, including those with pricing provisions tied to a consumer price or other index, have also been excluded as the
related consideration under the contract is variable at inception of the contract. Contract lengths vary from cancellable to multi-year.
The Registrants expect to recognize revenue for the following amounts related to fixed consideration associated with remaining performance obligations in each of
the future periods noted:

NOTE 7 — ASSET RETIREMENT OBLIGATIONS
DTE Electric has a legal retirement obligation for the decommissioning costs for its Fermi 1 and Fermi 2 nuclear plants, dismantlement of facilities located on
leased property, and various other operations. DTE Electric has conditional retirement obligations for asbestos and PCB removal at certain of its power plants and
various distribution equipment. DTE Gas has conditional retirement obligations for gas pipelines, certain service centers, and compressor and gate stations. The
Registrants recognize such obligations as liabilities at fair market value when they are incurred, which generally is at the time the associated assets are placed in service.
Fair value is measured using expected future cash outflows discounted at the Registrants' credit-adjusted risk-free rate. For its utility operations, the Registrants
recognize in the Consolidated Statements of Operations removal costs in accordance with regulatory treatment. Any differences between costs recognized related to
asset retirement and those reflected in rates are recognized as either a Regulatory asset or liability on the Consolidated Statements of Financial Position.
If a reasonable estimate of fair value cannot be made in the period in which the retirement obligation is incurred, such as for assets with indeterminate lives, the
liability is recognized when a reasonable estimate of fair value can be made. Natural gas storage system and certain other distribution assets for DTE Gas and
substations, manholes, and certain other distribution assets for DTE Electric have an indeterminate life. Therefore, no liability has been recorded for these assets.

Table of Contents
DTE Energy Company — DTE Electric Company
Combined Notes to Consolidated Financial Statements — (Continued)
Approximately $2.9 billion of the Asset retirement obligations represent nuclear decommissioning liabilities that are funded through a surcharge to electric
customers over the life of the Fermi 2 nuclear plant. The NRC has jurisdiction over the decommissioning of nuclear power plants and requires minimum
decommissioning funding based upon a formula. The MPSC and FERC regulate the recovery of costs of decommissioning nuclear power plants and both require the use
of external trust funds to finance the decommissioning of Fermi 2. Rates approved by the MPSC provide for the recovery of decommissioning costs of Fermi 2 and the
disposal of low-level radioactive waste. DTE Electric believes the MPSC collections will be adequate to fund the estimated cost of decommissioning. The
decommissioning assets, anticipated earnings thereon, and future revenues from decommissioning collections will be used to decommission Fermi 2. DTE Electric
expects the liabilities to be reduced to zero at the conclusion of the decommissioning activities. If amounts remain in the trust funds for Fermi 2 following the
completion of the decommissioning activities, those amounts will be disbursed based on rulings by the MPSC and FERC.
A portion of the funds recovered through the Fermi 2 decommissioning surcharge and deposited in external trust accounts is designated for the removal of non-
radioactive assets and returning the site to greenfield. This removal and greenfielding is not considered a legal liability. Therefore, it is not included in the asset
retirement obligation, but is reflected as the Nuclear decommissioning liability. The decommissioning of Fermi 1 is funded by DTE Electric. Contributions to the Fermi
1 trust are discretionary. For additional discussion of Nuclear decommissioning trust fund assets, see Note 11 to the Consolidated Financial Statements, "Fair Value."
NOTE 8 — REGULATORY MATTERS
Regulation
DTE Electric and DTE Gas are subject to the regulatory jurisdiction of the MPSC, which issues orders pertaining to rates, recovery of certain costs, including the
costs of generating facilities and regulatory assets, conditions of service, accounting, and operating-related matters. The MPSC has authorized a return on equity of 9.9%
for DTE Electric and 9.8% for DTE Gas, subject to changes from any pending or future rate case filings. DTE Electric is also regulated by the FERC with respect to
financing authorization, wholesale electric market activities, certain affiliate transactions, the acquisition and disposition of certain generation and other facilities, and,
in conjunction with the NERC, compliance with mandatory reliability standards. Regulation results in differences in the application of generally accepted accounting
principles between regulated and non-regulated businesses.
The Registrants are unable to predict the outcome of any unresolved regulatory matters discussed herein. Resolution of these matters is dependent upon future
MPSC and FERC orders and appeals, which may materially impact the Consolidated Financial Statements of the Registrants.
Regulatory Assets and Liabilities
DTE Electric and DTE Gas are required to record Regulatory assets and liabilities for certain transactions that would have been treated as revenue or expense in
non-regulated businesses. Continued applicability of regulatory accounting treatment requires that rates be designed to recover specific costs of providing regulated
services and be charged to and collected from customers. Future regulatory changes could result in the discontinuance of this accounting treatment for Regulatory assets
and liabilities for some or all of the Registrants' businesses and may require the write-off of the portion of any Regulatory asset or liability that was no longer probable
of recovery through regulated rates. Management believes that currently available facts support the continued use of Regulatory assets and liabilities and that all
Regulatory assets and liabilities are recoverable or refundable in the current regulatory environment.

As noted below, certain Regulatory assets for which costs have been incurred have been included (or are expected to be included, for costs incurred subsequent to
the most recently approved rate case) in DTE Electric's or DTE Gas' rate base, thereby providing a return on invested costs (except as noted). Certain other Regulatory
assets are not included in rate base but accrue recoverable carrying charges until surcharges to collect the assets are billed. Certain Regulatory assets do not result from
cash expenditures and therefore do not represent investments included in rate base or have offsetting liabilities that reduce rate base.

DTE Energy Company — DTE Electric Company
Combined Notes to Consolidated Financial Statements — (Continued)
ASSETS
•
Recoverable undepreciated costs on retiring plants — Undepreciated costs at the Belle River and Monroe power plants that will be retired in future periods.
These costs were approved for recovery as a result of DTE Electric's Integrated Resource Plan settlement agreement in 2023. The Belle River power plant will
be retired in 2025-2026 and the Monroe power plant will be retired in 2032. Amounts will be recovered in the future through securitization and amortization.
•
Recoverable pension and other postretirement costs — Accounting standards for pension and other postretirement benefit costs require, among other things, the
recognition in Other comprehensive income of the actuarial gains or losses and the prior service costs that arise during the period but are not immediately
recognized as components of net periodic benefit costs (credits). DTE Electric and DTE Gas record the impact of actuarial gains or losses and prior service
costs as Regulatory assets or Regulatory liabilities since the traditional rate setting process allows for the recovery of pension and other postretirement costs.
The asset and liability will reverse as the deferred items are amortized and recognized as components of net periodic benefit costs (credits). Refer to Note 19 to
the Consolidated Financial Statements, "Retirement Benefits and Trusteed Assets," for additional information regarding the changes in pension and other
postretirement costs for the period and the impact on Regulatory assets.
•
Fermi 2 asset retirement obligation — Obligation for Fermi 2 decommissioning costs. The asset captures the timing differences between expense recognition
and current recovery in rates and will reverse over the remaining life of the related plant.
•
Removal costs asset — Receivable for the recovery of asset removal expenditures in excess of amounts collected from customers.
•
Enhanced tree trimming program deferred costs — The MPSC approved the deferral of costs for a tree trimming surge through 2025, aimed at reducing the
number and duration of customer interruptions.
•
Recoverable Michigan income taxes — The State of Michigan enacted a corporate income tax resulting in the establishment of state deferred tax liabilities for
DTE Energy's utilities.  Offsetting Regulatory assets were also recorded as the impacts of the deferred tax liabilities will be reflected in rates as the related
taxable temporary differences reverse and flow through current income tax expense.
•
Recoverable income taxes related to AFUDC equity — Accounting standards for income taxes require recognition of a deferred tax liability for the equity
component of AFUDC.  A Regulatory asset is required for the future increase in taxes payable related to the equity component of AFUDC that will be
recovered from customers through future rates over the remaining life of the related plant.
•
Energy Waste Reduction incentive — DTE Electric and DTE Gas operate MPSC approved energy waste reduction programs designed to reduce overall energy
usage by their customers. The utilities are eligible to earn an incentive by exceeding statutory savings targets. The utilities have consistently exceeded the
savings targets and recognize the incentive as a Regulatory asset in the period earned.
•
Renewable ITC offset — DTE Electric's accounting policy for ITCs is to use the deferral method where the ITC benefit is deferred and amortized to net income
over the book life of the related property. For an ITC that is sold, this regulatory asset is used to adjust net income to reflect the benefit over a period shorter
than the book life, as approved by the MPSC.
•
Deferred environmental costs — The MPSC approved the deferral of investigation and remediation costs associated with DTE Gas' former MGP sites.
Amortization of deferred costs is over a ten-year period beginning in the year after costs were incurred, with recovery (net of any insurance proceeds) through
base rate filings.
•
Unamortized loss on reacquired debt — The unamortized discount, premium, and expense related to debt redeemed with a refinancing are deferred, amortized,
and recovered over the life of the replacement issue.

•
Customer360 deferred costs — The MPSC approved the deferral and amortization of certain costs associated with implementing Customer360, an integrated
software application that enables improved interface among customer service, billing, meter reading, credit and collections, device management, account
management, and retail access. Amortization of deferred costs over a 15-year amortization period began after the billing system was put into operation during
the second quarter of 2017. The deferred costs are recorded as Regulatory Assets at DTE Electric and DTE Gas receives an intercompany charge for their
proportionate share of amortization expense.
•
Ludington contract dispute costs — The MPSC approved the deferral of costs incurred for repairing or replacing defective work performed by a third party
related to the overhaul and upgrade of the Ludington Hydroelectric Pumped Storage Plant while the dispute is in litigation. These costs will be offset by any
potential future proceeds received related to the litigation. Upon resolution of the dispute, DTE Electric will have the opportunity to seek recovery through the
regulatory process for any remaining costs. Refer to the Ludington Plant Contract Dispute section of Note 17 to the Consolidated Financial Statements,
“Commitments and Contingencies,” for additional information regarding the complaint and ongoing legal proceedings.
•
Accrued PSCR/GCR revenue — Receivable for the temporary under-recovery of and carrying costs on fuel and purchased power costs incurred by DTE
Electric which are recoverable through the PSCR mechanism and temporary under-recovery of and carrying costs on gas costs incurred by DTE Gas which are
recoverable through the GCR mechanism.
•
Securitized regulatory assets — Costs approved for securitization and recovery by the MPSC. Amounts include the undepreciated cost of the River Rouge
power plant and tree trim surge costs. Securitization bond surcharges began in 2022 to recover the tree trimming costs over a period not to exceed 5 years and
River Rouge costs over a period not to exceed 14 years. Amounts also include the undepreciated costs of the St. Clair and Trenton Channel power plants.
Securitization bond surcharges began in 2023 to recover costs over a period not to exceed 15 years.

Regulatory assets not earning a return or accruing carrying charges.
LIABILITIES
•
Refundable federal income taxes — In December 2017, the TCJA was enacted and reduced the corporate income tax rate, effective January 1, 2018. DTE
Electric and DTE Gas remeasured deferred taxes, resulting in a reduction to deferred tax liabilities, to reflect the impact of the TCJA on the cumulative
temporary differences expected to reverse after the effective date. Regulatory liabilities were also recorded to offset the impact of the deferred tax
remeasurement reflected in rates.
•
Removal costs liability — The amounts collected from customers to fund future asset removal activities in excess of removal costs incurred.
•
Non-service pension and other postretirement costs — Upon adoption of ASU 2017-07 on January 1, 2018, certain non-service pension and other
postretirement cost activity is no longer credited to Property, plant, and equipment. Such costs may be recorded to Regulatory liabilities for ratemaking
purposes and refunded through credits to amortization expense based on the composite depreciation rate for plant-in-service.
•
Negative other postretirement offset — DTE Electric and DTE Gas' negative other postretirement costs have historically not been included as a reduction to
their authorized rates; therefore, DTE Electric and DTE Gas have accrued a Regulatory liability to eliminate the impact on earnings of the negative other
postretirement expense accrual. The Regulatory liabilities may reverse to the extent DTE Electric and DTE Gas' other postretirement expense is positive in
future years. As a result of MPSC orders, the Regulatory liability balances as of December 31, 2022 began to be amortized over a 7-year period for both DTE
Electric and DTE Gas.
•
Accrued PSCR/GCR refund — Liability for the temporary over-recovery of and a return on power supply costs and transmission costs incurred by DTE Electric
which are recoverable through the PSCR mechanism and temporary over-recovery of and a return on gas costs primarily incurred by DTE Gas which are
recoverable through the GCR mechanism.
•
Renewable energy — Amounts collected in excess of renewable energy expenditures, including subscription revenue related to MIGreenPower, DTE Electric's
voluntary renewable program providing customers the option to source their energy usage from renewables.

2024 Gas Rate Case Filing
DTE Gas filed a rate case with the MPSC on January 8, 2024 requesting an increase in base rates of $266 million based on a projected twelve-month period
ending September 30, 2025, and an increase in return on equity from 9.9% to 10.25%. The request reflected a net increase to customer rates of only $160 million, as an
existing IRM surcharge of $106 million would be rolled into the new base rates. The requested increase was primarily due to increased investments in plant related to
system reliability and pipeline safety and inflationary impacts on operating costs, partially offset by higher sales. On November 7, 2024, the MPSC issued an order
approving an annual revenue increase of $114 million for services rendered on or after November 21, 2024 and a return on equity of 9.8%.
2024 Electric Rate Case Filing
DTE Electric filed a rate case with the MPSC on March 28, 2024 requesting an increase in base rates of $456 million based on a projected twelve-month period
ending December 31, 2025, and an increase in return on equity from 9.9% to 10.5%. The requested increase in base rates was primarily due to the capital investments
required to support continued reliability improvements and the ongoing transition to cleaner energy. The requested increase in base rates was also due to the increased
cost of debt resulting from market dynamics and increasing operating and maintenance expenses.
On January 23, 2025, the MPSC issued an order approving an annual revenue increase of $217 million for services rendered on or after February 6, 2025 and a
return on equity of 9.9%. The MPSC order also disallowed $12 million of capital expenditures previously recorded, primarily related to various IT projects. The
disallowance was included in Asset (gains) losses and impairments, net on the Consolidated Statements of Operations for the year ended December 31, 2024.

DTE Energy Company — DTE Electric Company
Combined Notes to Consolidated Financial Statements — (Continued)
DTE Energy has a pre-tax federal net operating loss carryforward of $904 million as of December 31, 2024 which can be carried forward indefinitely. No
valuation allowance is required for the federal net operating loss deferred tax asset.
DTE Energy has state and local deferred tax assets related to net operating loss carryforwards of $68 million and $76 million at December 31, 2024 and 2023,
respectively. Most of the state and local net operating loss carryforwards expire from 2025 through 2046 with the remainder being carried forward indefinitely.
DTE Energy has recorded valuation allowances of $25 million and $39 million at December 31, 2024 and 2023, respectively. The valuation allowances include
$16 million and $19 million related to the state net operating loss carryforwards noted above and $3 million and $20 million related to charitable contribution
carryforwards as of the respective periods ended.
Tax credit carryforwards for DTE Electric include $583 million of general business credits that expire from 2036 through 2046. No valuation allowance is required
for the tax credit carryforwards deferred tax asset.
DTE Electric has a pre-tax federal net operating loss carryforward of $142 million as of December 31, 2024 which can be carried forward indefinitely. No
valuation allowance is required for the federal net operating loss deferred tax asset.
DTE Electric has $42 million and $49 million in state and local deferred tax assets related to net operating loss carryforwards at December 31, 2024 and 2023,
respectively, which will expire from 2030 through 2042. No valuation allowance is required for the state and local net operating loss deferred tax assets.
In assessing the realizability of deferred tax assets, DTE Energy considers whether it is more likely than not that some portion or all of the deferred tax assets will
not be realized. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during the periods in which those temporary
differences become deductible.
The above tables exclude unamortized ITCs that are shown separately on the Registrants' Consolidated Statements of Financial Position. DTE Energy's policy
election is to follow the flow-through method of accounting for ITCs earned from its non-utility businesses and the deferral method of accounting for its regulated
utilities due to different economic profiles of the various entities. The flow-through method used by the non-utility businesses recognizes ITCs in earnings when the
related assets are placed in service. The ITCs generated by the regulated utilities are deferred and amortized to earnings over the average life of the related property.
ITCs generated and sold by the regulated utilities are offset with a regulatory asset to give the benefit to customers over a period shorter than the book life, as approved
by the MPSC. Refer to Note 8 to the Consolidated Financial Statements, "Regulatory Matters" for the regulatory asset balance at December 31, 2024.
Uncertain Tax Positions
There were no unrecognized tax benefits at the Registrants for the years ended December 31, 2024 or 2023.
The Registrants recognize interest and penalties pertaining to income taxes in Interest expense and Other expenses, respectively, on the Consolidated Statements of
Operations. DTE Energy did not recognize any interest expense related to income taxes in 2024 and recognized a nominal amount of interest expense related to income
taxes in 2023 and 2022. DTE Electric did not recognize any interest expense related to income taxes in 2024 and recognized a nominal amount of interest expense in
2023 and $1 million in 2022. There was no accrued interest or penalties pertaining to income taxes for the Registrants at December 31, 2024 and 2023. Accrued interest
pertaining to income taxes at December 31, 2022 was $5 million and $8 million for DTE Energy and DTE Electric, respectively. There were no accrued penalties
pertaining to income taxes for the Registrants at December 31, 2022.
In 2024, DTE Energy, including DTE Electric, settled a federal tax audit for the 2022 tax year. DTE Energy's federal income tax returns for 2023 and subsequent
years remain subject to examination by the IRS. DTE Energy's Michigan Corporate Income Tax returns for the year 2019 and subsequent years remain subject to
examination by the State of Michigan. DTE Energy also files tax returns in numerous state and local jurisdictions with varying statutes of limitation.

NOTE 10 — EARNINGS PER SHARE
Basic earnings per share is calculated by dividing net income, adjusted for income allocated to participating securities, by the weighted average number of
common shares outstanding during the period. Diluted earnings per share reflect the dilution that would occur if any potentially dilutive instruments were exercised or
converted into common shares. DTE Energy's participating securities are restricted shares under the stock incentive program that contain rights to receive non-
forfeitable dividends. Performance shares do not receive cash dividends; as such, these awards are not considered participating securities. For additional information
regarding performance shares, see Note 20 to the Consolidated Financial Statements, "Stock-Based Compensation."

NOTE 11 — FAIR VALUE
Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the
measurement date in a principal or most advantageous market. Fair value is a market-based measurement that is determined based on inputs, which refer broadly to
assumptions that market participants use in pricing assets or liabilities. These inputs can be readily observable, market corroborated, or generally unobservable inputs.
The Registrants make certain assumptions they believe that market participants would use in pricing assets or liabilities, including assumptions about risk, and the risks
inherent in the inputs to valuation techniques. Credit risk of the Registrants and their counterparties is incorporated in the valuation of assets and liabilities through the
use of credit reserves, the impact of which was immaterial at December 31, 2024 and 2023. The Registrants believe they use valuation techniques that maximize the use
of observable market-based inputs and minimize the use of unobservable inputs.
A fair value hierarchy has been established that prioritizes the inputs to valuation techniques used to measure fair value in three broad levels. The fair value
hierarchy gives the highest priority to quoted prices (unadjusted) in active markets for identical assets or liabilities (Level 1) and the lowest priority to unobservable
inputs (Level 3). In some cases, the inputs used to measure fair value might fall in different levels of the fair value hierarchy. All assets and liabilities are required to be
classified in their entirety based on the lowest level of input that is significant to the fair value measurement in its entirety. Assessing the significance of a particular
input may require judgment considering factors specific to the asset or liability and may affect the valuation of the asset or liability and its placement within the fair
value hierarchy. The Registrants classify fair value balances based on the fair value hierarchy defined as follows:
•
Level 1 — Consists of unadjusted quoted prices in active markets for identical assets or liabilities that the Registrants have the ability to access as of the
reporting date.
•
Level 2 — Consists of inputs other than quoted prices included within Level 1 that are directly observable for the asset or liability or indirectly observable
through corroboration with observable market data.
•
Level 3 — Consists of unobservable inputs for assets or liabilities whose fair value is estimated based on internally developed models or methodologies using
inputs that are generally less readily observable and supported by little, if any, market activity at the measurement date. Unobservable inputs are developed
based on the best available information and subject to cost-benefit constraints.

Amounts represent assets valued at NAV as a practical expedient for fair value.
(b)
Amounts include $8 million and $11 million recorded in Restricted cash on DTE Electric's Consolidated Statements of Financial Position at December 31, 2024 and December 31, 2023, respectively. All
other amounts are included in Cash and cash equivalents on DTE Electric's Consolidated Statements of Financial Position.
Cash Equivalents
Cash equivalents include investments with maturities of three months or less when purchased. The cash equivalents shown in the fair value table are comprised of
short-term investments in money market funds.
Nuclear Decommissioning Trusts and Other Investments
The nuclear decommissioning trusts and other investments hold debt and equity securities directly and indirectly through commingled funds. Exchange-traded
debt and equity securities held directly, as well as publicly traded commingled funds, are valued using quoted market prices in actively traded markets. Non-exchange
traded fixed income securities are valued based upon quotations available from brokers or pricing services.
Non-publicly traded commingled funds holding exchange-traded equity or debt securities are valued based on stated NAVs. There are no significant restrictions for
these funds and investments may be redeemed with 7 to 65 days notice depending on the fund. There is no intention to sell the investment in these commingled funds.
Private equity and other assets include a diversified group of funds that are primarily classified as NAV assets. These funds primarily invest in limited partnerships,
including private equity, private real estate and private credit. Distributions are received through the liquidation of the underlying fund assets over the life of the funds.
There are generally no redemption rights. The limited partner must hold the fund for its life or find a third-party buyer, which may need to be approved by the general
partner. The funds are established with varied contractual durations generally in the range of 7 years to 12 years. The fund life can often be extended by several years by
the general partner, and further extended with the approval of the limited partners. Unfunded commitments related to these investments totaled $120 million and $157
million as of December 31, 2024 and 2023, respectively.

DTE Energy Company — DTE Electric Company
Combined Notes to Consolidated Financial Statements — (Continued)
Hedge funds and similar investments utilize a diversified group of strategies that attempt to capture uncorrelated sources of return. These investments include
publicly traded mutual funds that are valued using quoted prices in actively traded markets, as well as insurance-linked and asset-backed securities and that are valued
using quotations from broker or pricing services and limited partnerships that are classified as NAV assets.
For pricing the nuclear decommissioning trusts and other investments, a primary price source is identified by asset type, class, or issue for each security. The
trustee monitors prices supplied by pricing services and may use a supplemental price source or change the primary source of a given security if the trustee determines
that another price source is considered preferable. The Registrants have obtained an understanding of how these prices are derived, including the nature and
observability of the inputs used in deriving such prices.
Derivative Assets and Liabilities
Derivative assets and liabilities are comprised of physical and financial derivative contracts, including futures, forwards, options, and swaps that are both
exchange-traded and over-the-counter traded contracts. Various inputs are used to value derivatives depending on the type of contract and availability of market data.
Exchange-traded derivative contracts are valued using quoted prices in active markets. The Registrants consider the following criteria in determining whether a market
is considered active: frequency in which pricing information is updated, variability in pricing between sources or over time, and the availability of public information.
Other derivative contracts are valued based upon a variety of inputs including commodity market prices, broker quotes, interest rates, credit ratings, default rates,
market-based seasonality, and basis differential factors. The Registrants monitor the prices that are supplied by brokers and pricing services and may use a supplemental
price source or change the primary price source of an index if prices become unavailable or another price source is determined to be more representative of fair value.
The Registrants have obtained an understanding of how these prices are derived. Additionally, the Registrants selectively corroborate the fair value of their transactions
by comparison of market-based price sources. Mathematical valuation models are used for derivatives for which external market data is not readily observable, such as
contracts which extend beyond the actively traded reporting period. The Registrants have established a Risk Management Committee whose responsibilities include
directly or indirectly ensuring all valuation methods are applied in accordance with predefined policies. The development and maintenance of the Registrants' forward
price curves has been assigned to DTE Energy's Risk Management Department, which is separate and distinct from the trading functions within DTE Energy.

The unobservable inputs used in the fair value measurement of the electricity and natural gas commodity types consist of inputs that are less observable due in part
to lack of available broker quotes, supported by little, if any, market activity at the measurement date or are based on internally developed models. Certain basis prices
(i.e., the difference in pricing between two locations) included in the valuation of natural gas and electricity contracts were deemed unobservable. The weighted average
price for unobservable inputs was calculated using the average of forward price curves for natural gas and electricity and the absolute value of monthly volumes.
The inputs listed above would have had a direct impact on the fair values of the above security types if they were adjusted. A significant increase (decrease) in the
basis price would have resulted in a higher (lower) fair value for long positions, with offsetting impacts to short positions.

Other Securities
At December 31, 2024 and 2023, DTE Energy's securities included in Other investments on the Consolidated Statements of Financial Position consisted primarily
of investments within DTE Energy's rabbi trust. The rabbi trust is comprised primarily of trading securities recorded at fair value, as well as debt securities classified as
held-to-maturity and recorded at amortized cost. The trust was established to fund certain non-qualified pension benefits, and therefore changes in market value of the
trading securities and interest on the held-to-maturity securities are recognized in earnings. Gains and losses are allocated from DTE Energy to DTE Electric and are
included in Other Income or Other Expense, respectively, in the Registrants' Consolidated Statements of Operations. Gains (losses) related to the trading securities were
immaterial for the years ended December 31, 2024, 2023, and 2022.

NOTE 12 — FINANCIAL AND OTHER DERIVATIVE INSTRUMENTS
The Registrants recognize all derivatives at their fair value as Derivative assets or liabilities on their respective Consolidated Statements of Financial Position
unless they qualify for certain scope exceptions, including the normal purchases and normal sales exception. Further, derivatives that qualify and are designated for
hedge accounting are classified as either hedges of a forecasted transaction or the variability of cash flows to be received or paid related to a recognized asset or liability
(cash flow hedge); or as hedges of the fair value of a recognized asset or liability or of an unrecognized firm commitment (fair value hedge). For cash flow hedges, the
derivative gain or loss is deferred in Accumulated other comprehensive income (loss) and later reclassified into earnings when the underlying transaction occurs. For
fair value hedges, changes in fair values for the derivative and hedged item are recognized in earnings each period. For derivatives that do not qualify or are not
designated for hedge accounting, changes in fair value are recognized in earnings each period.
The Registrants' primary market risk exposure is associated with commodity prices, credit, and interest rates. The Registrants have risk management policies to
monitor and manage market risks. The Registrants use derivative instruments to manage some of the exposure. DTE Energy uses derivative instruments for trading
purposes in its Energy Trading segment. Contracts classified as derivative instruments include electricity, natural gas, oil, certain environmental contracts, forwards,
futures, options, swaps, and foreign currency exchange contracts. Items not classified as derivatives include natural gas and environmental inventory, pipeline
transportation contracts, some environmental contracts, and natural gas storage assets.
DTE Electric — DTE Electric generates, purchases, distributes, and sells electricity. DTE Electric uses forward contracts to manage changes in the price of
electricity and fuel. Substantially all of these contracts meet the normal purchases and normal sales exception and are therefore accounted for under the accrual method.
Other derivative contracts are MTM and recoverable through the PSCR mechanism when settled. This results in the deferral of unrealized gains and losses as
Regulatory assets or liabilities until realized.
DTE Gas — DTE Gas purchases, stores, transports, distributes, and sells natural gas, and buys and sells transportation and storage capacity. DTE Gas has fixed-
priced contracts for portions of its expected natural gas supply requirements through March 2027. Substantially all of these contracts meet the normal purchases and
normal sales exception and are therefore accounted for under the accrual method. Forward transportation and storage contracts are generally not derivatives and are
therefore accounted for under the accrual method.
DTE Vantage — DTE Vantage manages and operates renewable gas recovery projects, power generation assets, and other customer specific energy solutions.
Long-term contracts and hedging instruments are used in the marketing and management of the segment assets. These contracts and hedging instruments are generally
not derivatives and are therefore accounted for under the accrual method.
Energy Trading — Commodity Price Risk — Energy Trading markets and trades electricity, natural gas physical products, and energy financial instruments, and
provides energy and asset management services utilizing energy commodity derivative instruments. Forwards, futures, options, and swap agreements are used to
manage exposure to the risk of market price and volume fluctuations in its operations. These derivatives are accounted for by recording changes in fair value to earnings
unless hedge accounting criteria are met.
Energy Trading — Foreign Currency Exchange Risk — Energy Trading has foreign currency exchange forward contracts to economically hedge fixed Canadian
dollar commitments existing under natural gas and power purchase and sale contracts and natural gas transportation contracts. Energy Trading enters into these contracts
to mitigate price volatility with respect to fluctuations of the Canadian dollar relative to the U.S. dollar. These derivatives are accounted for by recording changes in fair
value to earnings unless hedge accounting criteria are met.
Corporate and Other — Interest Rate Risk — DTE Energy may use interest rate swaps, treasury locks, and other derivatives to hedge the risk associated with
interest rate market volatility.
Credit Risk — DTE Energy maintains credit policies that significantly minimize overall credit risk. These policies include an evaluation of potential customers’
and counterparties’ financial condition, including the viability of underlying productive assets, credit rating, collateral requirements, or other credit enhancements such
as letters of credit or guarantees. DTE Energy generally uses standardized agreements that allow the netting of positive and negative transactions associated with a
single counterparty. DTE Energy maintains a provision for credit losses based on factors surrounding the credit risk of its customers, historical trends, and other
information. Based on DTE Energy's credit policies and its December 31, 2024 provision for credit losses, DTE Energy’s exposure to counterparty nonperformance is
not expected to have a material adverse effect on DTE Energy's Consolidated Financial Statements.

Derivative Activities
DTE Energy manages its MTM risk on a portfolio basis based upon the delivery period of its contracts and the individual components of the risks within each
contract. Accordingly, it records and manages the energy purchase and sale obligations under its contracts in separate components based on the commodity (e.g.
electricity or natural gas), the product (e.g. electricity for delivery during peak or off-peak hours), the delivery location (e.g. by region), the risk profile (e.g. forward or
option), and the delivery period (e.g. by month and year). The following describes the categories of activities represented by their operating characteristics and key risks:
•
Asset Optimization — Represents derivative activity associated with assets owned and contracted by DTE Energy, including forward natural gas purchases
and sales, natural gas transportation, and storage capacity. Changes in the value of derivatives in this category typically economically offset changes in the
value of underlying non-derivative positions, which do not qualify for fair value accounting. The difference in accounting treatment of derivatives in this
category and the underlying non-derivative positions can result in significant earnings volatility.
•
Marketing and Origination — Represents derivative activity transacted by originating substantially hedged positions with wholesale energy marketers,
producers, end-users, utilities, retail aggregators, and alternative energy suppliers.
•
Fundamentals Based Trading — Represents derivative activity transacted with the intent of taking a view, capturing market price changes, or putting capital
at risk. This activity is speculative in nature as opposed to hedging an existing exposure.
•
Other — Includes derivative activity at DTE Electric related to FTRs. Changes in the value of derivative contracts at DTE Electric are recorded as Derivative
assets or liabilities, with an offset to Regulatory assets or liabilities as the settlement value of these contracts will be included in the PSCR mechanism when
realized.

Certain of DTE Energy's derivative positions are subject to netting arrangements which provide for offsetting of asset and liability positions as well as related cash
collateral. Such netting arrangements generally do not have restrictions. Under such netting arrangements, DTE Energy offsets the fair value of derivative instruments
with cash collateral received or paid for those contracts executed with the same counterparty, which reduces DTE Energy's Total Assets and Liabilities. Cash collateral is
allocated between the fair value of derivative instruments and customer accounts receivable and payable with the same counterparty on a pro-rata basis to the extent
there is exposure. Any cash collateral remaining, after the exposure is netted to zero, is reflected in Accounts receivable and Accounts payable as collateral paid or
received, respectively.
DTE Energy also provides and receives collateral in the form of letters of credit which can be offset against net Derivative assets and liabilities as well as Accounts
receivable and payable. DTE Energy had letters of credit of $1 million issued and outstanding at December 31, 2024 and $3 million at December 31, 2023, which could
be used to offset net Derivative liabilities. There were no letters of credit received from third parties which could be used to offset net Derivative assets at December 31,
2024 and there were $10 million at December 31, 2023. Such balances of letters of credit are excluded from the tables below and are not netted with the recognized
assets and liabilities in DTE Energy's Consolidated Statements of Financial Position.
For contracts with certain clearing agents, the fair value of derivative instruments is netted against realized positions with the net balance reflected as either 1) a
Derivative asset or liability or 2) an Account receivable or payable. Other than certain clearing agents, Accounts receivable and Accounts payable that are subject to
netting arrangements have not been offset against the fair value of Derivative assets and liabilities.

Revenues and energy costs related to trading contracts are presented on a net basis in DTE Energy's Consolidated Statements of Operations. Commodity
derivatives used for trading purposes, and financial non-trading commodity derivatives, are accounted for using the MTM method with unrealized and realized gains
and losses recorded in Operating Revenues — Non-utility operations. Non-trading physical commodity sale and purchase derivative contracts are generally accounted
for using the MTM method with unrealized and realized gains and losses for sales recorded in Operating Revenues — Non-utility operations and purchases recorded in
Fuel, purchased power, gas, and other — non-utility.
The following represents the cumulative gross volume of DTE Energy's derivative contracts outstanding as of December 31, 2024:

Various subsidiaries and equity investees of DTE Energy have entered into derivative and non-derivative contracts which contain ratings triggers and are
guaranteed by DTE Energy. These contracts contain provisions which allow the counterparties to require that DTE Energy post cash or letters of credit as collateral in
the event that DTE Energy’s credit rating is downgraded below investment grade. Certain of these provisions (known as "hard triggers") state specific circumstances
under which DTE Energy can be required to post collateral upon the occurrence of a credit downgrade, while other provisions (known as "soft triggers") are not as
specific. For contracts with soft triggers, it is difficult to estimate the amount of collateral which may be requested by counterparties and/or which DTE Energy may
ultimately be required to post. The amount of such collateral which could be requested fluctuates based on commodity prices (primarily natural gas, power, and
environmental) and the provisions and maturities of the underlying transactions. As of December 31, 2024, DTE Energy's contractual obligation to post collateral in the
form of cash or letters of credit in the event of a downgrade to below investment grade, under both hard trigger and soft trigger provisions, was $360 million.
As of December 31, 2024, DTE Energy had $467 million of derivatives in net liability positions, for which hard triggers exist. There is no collateral that has been
posted against such liabilities, including cash and letters of credit. Associated derivative net asset positions for which contractual offset exists were $402 million. The net
remaining amount of $65 million is derived from the $360 million noted above.

Junior Subordinated Debentures
DTE Energy has the right to defer interest payments on the Junior Subordinated Debentures. Should DTE Energy exercise this right, it cannot declare or pay
dividends on, or redeem, purchase or acquire, any of its capital stock during the deferral period. Any deferred interest payments will bear additional interest at the rate
associated with the related debt issue. As of December 31, 2024, no interest payments have been deferred on the Junior Subordinated Debentures.
Cross Default Provisions
Substantially all of the net utility properties of DTE Electric and DTE Gas are subject to the lien of mortgages. Should DTE Electric or DTE Gas fail to timely pay
their indebtedness under these mortgages, such failure may create cross defaults in the indebtedness of DTE Energy.

NOTE 15 — SHORT-TERM CREDIT ARRANGEMENTS AND BORROWINGS
DTE Energy, DTE Electric, and DTE Gas have unsecured revolving credit agreements that can be used for general corporate borrowings, but are intended to
provide liquidity support for each of the companies’ commercial paper programs. Borrowings under the revolvers are available at prevailing short-term interest rates.
Letters of credit of up to $500 million may also be issued under the DTE Energy revolver. DTE Energy and DTE Electric also have other facilities to support letter of
credit issuance and increase liquidity.
The unsecured revolving credit agreements require a total funded debt to capitalization ratio of no more than 0.70 to 1 for DTE Energy and 0.65 to 1 for DTE
Electric and DTE Gas. In the agreements, "total funded debt" means all indebtedness of each respective company and their consolidated subsidiaries, including finance
lease obligations, hedge agreements, and guarantees of third parties’ debt, but excluding contingent obligations, nonrecourse and junior subordinated debt, and certain
equity-linked securities and, except for calculations at the end of the second quarter, certain DTE Gas short-term debt. "Capitalization" means the sum of (a) total funded
debt plus (b) "consolidated net worth," which is equal to consolidated total equity of each respective company and their consolidated subsidiaries (excluding pension
effects under certain FASB statements), as determined in accordance with accounting principles generally accepted in the United States of America. At December 31,
2024, the total funded debt to total capitalization ratios for DTE Energy, DTE Electric, and DTE Gas were 0.65 to 1, 0.52 to 1, and 0.49 to 1, respectively, and were in
compliance with this financial covenant.

For both DTE Energy and DTE Electric, the weighted average interest rate for short-term borrowings was 4.7% and 5.6% at December 31, 2024 and 2023,
respectively. For information related to affiliate short-term borrowings, refer to Note 22 of the Consolidated Financial Statements, "Related Party Transactions."
In conjunction with maintaining certain exchange-traded risk management positions, DTE Energy may be required to post collateral with a clearing agent. DTE
Energy has a demand financing agreement with its clearing agent which allows the right of setoff with posted collateral. At December 31, 2024, the capacity under the
facility was $200 million. The amounts outstanding under demand financing agreements were $49 million and $152 million at December 31, 2024 and 2023,
respectively, and were fully offset by posted collateral.
Dividend Restrictions
Certain of DTE Energy’s credit facilities contain a provision requiring DTE Energy to maintain a total funded debt to capitalization ratio, as defined in the
agreements, of no more than 0.70 to 1, which has the effect of limiting the amount of dividends DTE Energy can pay in order to maintain compliance with this
provision. At December 31, 2024, the effect of this provision was a restriction on dividend payments to no more than $2.5 billion of DTE Energy's Retained earnings of
$4.9 billion. There are no other effective limitations with respect to DTE Energy’s ability to pay dividends.
NOTE 16 — LEASES
Lessee
Leases at DTE Energy and DTE Electric are primarily comprised of various forms of certain easement leases, coal railcars, building equipment, and computer
hardware, leases with terms ranging from approximately 1 to 52 years.
A lease is deemed to exist when the Registrants have the right to control the use of identified property, plant or equipment, as conveyed through a contract, for a
certain period of time and consideration paid. The right to control is deemed to occur when the Registrants have the right to obtain substantially all of the economic
benefits of the identified assets and the right to direct the use of such assets.

Lease liabilities are determined utilizing a discount rate to determine the present values of lease payments. Topic 842 requires the use of the rate implicit in the
lease when it is readily determinable. When the rate implicit in the lease is not readily determinable, the incremental borrowing rate is used. The Registrants have
determined their respective incremental borrowing rates based upon the rate of interest that would have been paid on a collateralized basis over similar tenors to that of
the leases. The incremental borrowing rates for DTE Electric and DTE Gas have been determined utilizing respective secured borrowing rates for first mortgage bonds
with like tenors of remaining lease terms. Incremental borrowing rates for non-utility entities have been determined utilizing an implied secured borrowing rate based
upon an unsecured rate for a similar tenor of remaining lease terms, which is then adjusted for the estimated impact of collateral.
Certain leases of the Registrants contain escalation clauses whereby the payments are adjusted for consumer price or labor indices. The Registrants have leases
with non-index based escalation clauses for percentage increases. DTE Energy also has leases with variable payments based upon usage of, or revenues associated with,
the leased assets. DTE Electric also has leases with variable payments based upon the usage of the leased assets.
Certain leases of easements and coal railcars contain provisions whereby the Registrants have the option to terminate the lease agreement by giving notice of such
termination during the time frames specified in the respective lease. The Registrants have considered such provisions in the determination of the lease term when it is
reasonably certain that the lease would be terminated.
The Registrants have certain leases which contain purchase options. Based upon the nature of the leased property and terms of the purchase options, the
Registrants have determined it is not reasonably certain that such purchase options will be utilized. Thus, the impact of the purchase options has not been included in the
determination of right-of-use assets and lease liabilities for the subject leases.
The Registrants have certain leases which contain renewal options. Where the renewal options were deemed reasonably certain to occur, the impacts of such
options were included in the determination of the right of use assets and lease liabilities.
The Registrants have agreements with lease and non-lease components, which are generally accounted for separately. Consideration in a lease is allocated between
lease and non-lease components based upon the estimated relative standalone prices. The Registrants have certain coal railcar leases for which non-lease and lease
components are accounted for as a single lease component, as permitted under Topic 842.

DTE Energy leases various assets under operating leases for a pipeline, energy facilities and related equipment. Such leases are comprised of both fixed payments
and variable payments which are contingent on volumes, with terms ranging from 9 to 24 years. Generally, the operating leases do not have renewal provisions or
options to purchase the assets at the end of the lease. The operating leases generally do not have termination for convenience provisions. Termination may be allowed
under specific circumstances stated in the lease contract, such as under an event of default.
Certain of the finance and operating leases have lease terms that extend to the end of the estimated economic life of the leased assets, thereby resulting in no
residual value. Any remaining residual values under the finance and operating leases are expected to be recovered through rates, renewals or new lease contracts.
Residual values have been determined using the estimated economic life of the leased assets. The finance and operating leases do not contain residual value guarantees.
Certain of the operating leases have both lease and non-lease components. The lease and non-lease components are allocated based upon estimated relative
standalone selling prices.
A lease is deemed to exist when the Registrants have provided other parties with the right to control the use of identified property, plant or equipment, as conveyed
through a contract, for a certain period of time and consideration received. The right to control is deemed to occur when the Registrants have provided other parties with
the right to obtain substantially all of the economic benefits of the identified assets and the right to direct the use of such assets.

NOTE 17 — COMMITMENTS AND CONTINGENCIES
Environmental
DTE Electric
Air — DTE Electric is subject to the EPA ozone and fine particulate transport and acid rain regulations that limit power plant emissions of SO  and NO . The EPA
and the state of Michigan have also issued emission reduction regulations relating to ozone, fine particulate, regional haze, mercury, and other air pollution. These rules
have led to controls on fossil-fueled power plants to reduce SO , NO , mercury, and other emissions. Additional rule making may occur over the next few years which
could require additional controls for SO , NO , and other hazardous air pollutants.
In March 2024, the EPA finalized the NAAQS for fine particulate matter, particles of pollution with diameters generally 2.5 micrometers and smaller (PM2.5). It is
likely that areas of Michigan in which DTE Electric operates will be designated as non-attainment in the future and the state will be required to develop a SIP for such
areas. No impact is expected in the near term, and any long-term financial impacts cannot be assessed at this time.
In April 2024, the EPA finalized new rules to address emissions of GHGs from existing, new, modified, or reconstructed sources in the power sector. The new rules
may impact future electric generation plans that will be defined in DTE Electric's next Integrated Resource Plan filing. Challenges to the rules have been filed, and DTE
Electric will continue to monitor regulatory developments. The financial impacts of the new rules are still being assessed.
Pending or future legislation or other regulatory actions could have a material impact on DTE Electric's operations and financial position and the rates charged to
its customers. Potential impacts include expenditures for environmental equipment beyond what is currently planned, financing costs related to additional capital
expenditures, the purchase of emission credits from market sources, higher costs of purchased power, and the retirement of facilities where control equipment is not
economical. DTE Electric would seek to recover these incremental costs through increased rates charged to its utility customers, as authorized by the MPSC.
To comply with air pollution requirements, DTE Electric has spent approximately $2.4 billion. DTE Electric does not anticipate additional capital expenditures for
air pollution requirements, subject to the results of future rulemakings.
Water — In response to EPA regulations and in accordance with the Clean Water Act section 316(b), DTE Electric was required to examine alternatives for
reducing the environmental impacts of the cooling water intake structures at several of its facilities. A final rule became effective in October 2014, which required
studies to be completed and submitted as part of the NPDES permit application process to determine the type of technology needed to reduce impacts to fish. DTE
Electric has completed the required studies and submitted reports for most of its generation plants, and a final study is in-process for Monroe power plant. Final
compliance for the installation of any required technology to reduce the impacts of water intake structures will be determined by the state on a case by case, site specific
basis.
As part of the Monroe power plant NPDES permit, EGLE has added an option to evaluate the thermal discharge of the facility as it relates to Clean Water Act
section 316(a) regulations in order to establish an appropriate temperature discharge limit. DTE Electric has submitted to EGLE a biological demonstration study plan to
evaluate the thermal discharge impacts to an aquatic community. After approval of the plan by EGLE and completion of field sampling, data will be processed and
compiled into a comprehensive report. At the present time, DTE Electric cannot predict the outcome of this evaluation or financial impact.

Contaminated and Other Sites — Prior to the construction of major interstate natural gas pipelines, gas for heating and other uses was manufactured locally from
processes involving coal, coke, or oil. The facilities, which produced gas, have been designated as MGP sites. DTE Electric conducted remedial investigations at
contaminated sites, including three former MGP sites. The investigations at the former MGP sites have revealed contamination related to the by-products of gas
manufacturing. Cleanup of one of the MGP sites is complete, and that site is closed. DTE Electric has also completed partial closure of one additional site. Cleanup
activities associated with the remaining sites will continue over the next several years. In addition to the MGP sites, DTE Electric is also in the process of cleaning up
other contaminated sites, including the area surrounding an ash landfill, electrical distribution substations, electric generating power plants, and underground and above
ground storage tank locations. The findings of these investigations indicated that the estimated cost to remediate these sites is expected to be incurred over the next
several years. At December 31, 2024 and 2023, DTE Electric had $10 million and $9 million, respectively, accrued for remediation. These costs are not discounted to
their present value. Any change in assumptions, such as remediation techniques, nature and extent of contamination, and regulatory requirements, could impact the
estimate of remedial action costs for the sites and affect DTE Electric’s financial position and cash flows. DTE Electric believes the likelihood of a material change to
the accrued amount is remote based on current knowledge of the conditions at each site.
Coal Combustion Residuals and Effluent Limitations Guidelines — A final EPA rule for the disposal of coal combustion residuals, commonly known as coal ash,
became effective in October 2015 and has continued to be updated in subsequent years. The rule is based on the continued listing of coal ash as a non-hazardous waste
and relies on various self-implementation design and performance standards. DTE Electric currently owns and operates multiple coal ash storage facilities to manage
coal ash from coal-fired power plants that are subject to federal, state, and local CCR and solid waste regulations. At certain facilities, the rule required ongoing
sampling and testing of monitoring wells, compliance with groundwater standards, and closure.
On May 8, 2024, the EPA finalized a new rule to regulate legacy CCR surface impoundments and CCR management units. The rule expands the reach of the CCR
rule to inactive electric generation sites and previously unregulated CCR at any active facility. The rule also extends the dewatering and stabilization criteria of the
closure in place performance standards to existing CCR landfills. DTE Electric has no legacy CCR surface impoundments, but does have existing CCR landfills and is
evaluating sites for CCR management units. DTE Electric is in the process of evaluating the final rule, which may have significant financial impacts depending on the
site-specific characteristics of the units that are regulated by the new rule. Long-term financial impacts cannot be clearly defined at this time and likely will not be
clearly defined until the regulated units are identified. Challenges to the rule have been filed, and DTE Electric will continue to monitor for regulatory developments.
The preliminary cost estimate to comply with the revised rule is approximately $289 million as of December 31, 2024, and is recorded to Asset retirement obligations.
The estimate will be updated as necessary when site-specific details are more fully known. These costs are expected to be recoverable under the regulatory construct as
part of removal costs.
At the state level, legislation was signed in December 2018 and provides for further regulation of the CCR program in Michigan. Additionally, the statutory
revision provides the basis of a CCR program that EGLE has submitted to the EPA for approval to fully regulate the CCR program in Michigan in lieu of a federal
permit program. The EPA is currently working with EGLE in reviewing the submitted state program, and DTE Electric will work with EGLE to implement the state
program that may be approved in the future.
The EPA has updated and revised the ELG in 2015, 2020, and 2024. In each revision, EPA has re-established technology-based standards applicable to
wastewaters created at facilities with an electrical generating unit. In each revision, the EPA also established new applicability dates.
The Reconsideration Rule, finalized in 2020, provided additional opportunities by finalizing a group of compliance subcategories that provided cessation of coal
as a compliance option. Additionally, the 2020 Reconsideration Rule established the Voluntary Incentives Program (VIP) for FGD wastewater compliance only. If a
facility applies for the VIP, they must meet more stringent standards, but are allowed an extended time period to meet the compliance requirements by December 1,
2028. The Reconsideration Rule provided these new opportunities for DTE Electric to evaluate existing ELG compliance strategies and make any necessary adjustments
to ensure full compliance with the ELGs in a cost-effective manner.
Compliance schedules for individual facilities and individual waste streams are determined through issuance of new NPDES permits by the state of Michigan. The
state of Michigan issued an NPDES permit for the Belle River power plant establishing compliance deadlines based on the 2020 Reconsideration Rule. On October 11,
2021, DTE Electric submitted a Notice of Planned Participation (NOPP) to the state of Michigan that formally announced the intent to pursue compliance subcategories
as ELG compliance options: the cessation of coal at the Belle River power plant no later than December 31, 2028 and the VIP for FGD wastewater at Monroe power
plant by December 31, 2028.

Table of Contents
DTE Energy Company — DTE Electric Company
Combined Notes to Consolidated Financial Statements — (Continued)
The EPA also finalized Supplemental ELG Rules on May 9, 2024. This updated the regulations from the 2020 Reconsideration Rule for FGD wastewater, bottom
ash transport water (BATW), combustion residual leachate (CRL), and legacy wastewater (LWW). The supplemental rule established new technology-based effluent
limitations guidelines and standards applicable to FGD wastewater, BATW, CRL, and LWW. The applicability date for BATW is as soon as possible beginning July 8,
2024 and no later than December 31, 2029. FGD wastewater retrofits must be completed as soon as possible, beginning July 8, 2024 and no later than December, 31
2029 or December 31, 2028 if a permittee is pursuing the VIP subcategory for FGD wastewater. The Cessation of Coal compliance subcategory and VIP from the 2020
Reconsideration Rule were maintained in the 2024 Supplemental Rule and continue to be a fundamental component of DTE Electric's ELG compliance strategy.
DTE Electric's compliance strategy includes the conversion of the two generating units at the Belle River power plant to a natural gas peaking resource in 2025-
2026, which was included in the NOPP filed in 2021. DTE Electric also submitted a new NOPP to apply for the cessation of coal compliance subcategory for generating
units 3 and 4 at the Monroe power plant. DTE Electric plans to retire Monroe's generating units 1 and 2 in 2032.
DTE Electric continues to evaluate compliance strategies, technologies and system designs to achieve compliance with the EPA rules at the Monroe power plant in
accordance with the VIP subcategory for FGD and new discharge requirements for BATW. Additionally, DTE Electric is evaluating compliance strategies and options to
address new requirement and deadlines for other wastewater streams in the 2024 Supplemental Rule at both Belle River Power Plant and Sibley Quarry.
DTE Electric currently estimates the impact of the CCR and ELG rules to be $509 million of capital expenditures through 2029. This estimate may change in
future periods as DTE Electric evaluates the CCR and ELG rules discussed above that have recently been finalized.
DTE Gas
Contaminated and Other Sites — DTE Gas owns or previously owned 14 former MGP sites. Investigations have revealed contamination related to the by-products
of gas manufacturing at each site. Cleanup of eight MGP sites is complete and those sites are closed. DTE Gas has also completed partial closure of four additional sites.
Cleanup activities associated with the remaining sites will continue over the next several years. The MPSC has established a cost deferral and rate recovery mechanism
for investigation and remediation costs incurred at former MGP sites. In addition to the MGP sites, DTE Gas is also in the process of cleaning up other contaminated
sites, including gate stations, gas pipeline releases, and underground storage tank locations. As of December 31, 2024 and 2023, DTE Gas had $26 million accrued for
remediation. These costs are not discounted to their present value. Any change in assumptions, such as remediation techniques, nature and extent of contamination, and
regulatory requirements, could impact the estimate of remedial action costs for the sites and affect DTE Gas' financial position and cash flows. DTE Gas anticipates the
cost amortization methodology approved by the MPSC, which allows for amortization of the MGP costs over a ten-year period beginning with the year subsequent to
the year the MGP costs were incurred, will prevent the associated investigation and remediation costs from having a material adverse impact on DTE Gas' results of
operations.
Air — In March 2023, the EPA published the Good Neighbor Rule, which includes provisions for compressor engines operated for the transportation of natural
gas. In June 2024, the United States Supreme Court issued an opinion granting emergency applications to stay the Good Neighbor Rule. The stay will remain in effect
during other litigation. The status of the rule remains uncertain as litigation is ongoing. At this time, DTE Gas does not expect a significant financial impact.
As noted above for DTE Electric, the EPA finalized the NAAQS for fine particulate matter in March 2024. It is likely that areas of Michigan in which DTE Gas
operates will be designated as non-attainment in the future and the state will be required to develop a SIP for such areas. No impact is expected in the near term, and any
long-term financial impacts cannot be assessed at this time.
Non-utility
DTE Energy's non-utility businesses are subject to a number of environmental laws and regulations dealing with the protection of the environment from various
pollutants.

DTE Energy Company — DTE Electric Company
Combined Notes to Consolidated Financial Statements — (Continued)
In March 2019, the EPA issued an FOV to EES Coke Battery, LLC ("EES Coke"), the Michigan coke battery facility that is a wholly-owned subsidiary of DTE
Energy, alleging that the 2008 and 2014 permits issued by EGLE did not comply with the Clean Air Act. In September 2020, the EPA issued another FOV alleging EES
Coke's 2018 and 2019 SO2 emissions exceeded projections and hence violated non-attainment new source review permitting requirements. EES Coke evaluated the
EPA's alleged violations and believes that the permits approved by EGLE complied with the Clean Air Act. EES Coke responded to the EPA's September 2020
allegations demonstrating its actual emissions are compliant with non-attainment new source review requirements. On June 1, 2022, the U.S. Department of Justice
("DOJ"), on behalf of the EPA, filed a complaint against EES Coke in the U.S. District Court for the Eastern District of Michigan alleging that EES Coke failed to
comply with non-attainment new source review requirements under the Clean Air Act when it applied for the 2014 permit. In November 2022, the Sierra Club and City
of River Rouge were granted intervention. On May 20, 2024, the court granted a motion allowing the DOJ to amend their complaint to add EES Coke's parent entities,
including DTE Energy, as defendants. The parent entities were added in an attempt to share in any potential liability; there are no additional claims alleged. The case is
proceeding through discovery and trial is set for July 2025. At the present time, DTE Energy cannot predict the outcome or financial impact of this matter.
Other
In 2010, the EPA finalized a new one-hour SO  ambient air quality standard that requires states to submit plans and associated timelines for non-attainment areas
that demonstrate attainment with the new SO  standard in phases. Phase 1 addresses non-attainment areas designated based on ambient monitoring data. Phase 2
addresses non-attainment areas with large sources of SO  and modeled concentrations exceeding the National Ambient Air Quality Standards for SO . Phase 3 addresses
smaller sources of SO  with modeled or monitored exceedances of the new SO  standard.
Michigan's Phase 1 non-attainment area included DTE Energy facilities. However, the EPA published a Federal Implementation Plan (FIP) for the area in June
2022 that did not impact any DTE Energy facilities. It is also not expected that Phase 3 will have any impact on DTE Energy.
Michigan's Phase 2 non-attainment area includes DTE Electric facilities in St. Clair County. The EPA approved a clean data determination request submitted by
EGLE. This determination suspends certain planning requirements and sanctions for the non-attainment area for as long as the area continues to attain the 2010 SO2 air
quality standards, but this does not automatically redesignate the area to attainment. Until the area is officially redesignated as attainment, DTE Energy is unable to
determine the impacts.
REF Guarantees
DTE Energy provided certain guarantees and indemnities in conjunction with the sales of interests in or lease of its previously operated REF facilities. The
guarantees cover potential commercial, environmental, and tax-related obligations that will survive until 90 days after expiration of all applicable statutes of limitations.
DTE Energy estimates that its maximum potential liability under these guarantees at December 31, 2024 was $216 million. Payments under these guarantees are
considered remote.
Other Guarantees
In certain limited circumstances, the Registrants enter into contractual guarantees. The Registrants may guarantee another entity’s obligation in the event it fails to
perform and may provide guarantees in certain indemnification agreements. The Registrants may also provide indirect guarantees for the indebtedness of others. DTE
Energy’s guarantees are not individually material with maximum potential payments totaling $69 million at December 31, 2024. Payments under these guarantees are
considered remote.
The Registrants are periodically required to obtain performance surety bonds in support of obligations to various governmental entities and other companies in
connection with its operations. As of December 31, 2024, DTE Energy had $368 million of performance bonds outstanding, including $193 million for DTE Electric.
Performance bonds are not individually material, except for $130 million of bonds supporting Energy Trading operations. These bonds are meant to provide
counterparties with additional assurance that Energy Trading will meet its contractual obligations for various commercial transactions. The terms of the bonds align with
those of the underlying Energy Trading contracts and are estimated to be outstanding approximately 1 to 3 years. In the event that any performance bonds are called for
nonperformance, the Registrants would be obligated to reimburse the issuer of the performance bond. The Registrants are released from the performance bonds as the
contractual performance is completed and does not believe that a material amount of any currently outstanding performance bonds will be called.

(a)
The agreements represent the minimum obligations with suppliers for renewable energy and renewable energy credits under existing contract terms which expire from 2030 through 2049. DTE Electric's
share of plant output ranges from 28% to 100%. Purchase commitments for DTE Electric include affiliate agreements with DTE Sustainable Generation that are eliminated in consolidation for DTE Energy.
(b)
Excludes amounts associated with full requirements contracts where no stated minimum purchase volume is required.
Utility capital expenditures and expenditures for non-utility businesses will be approximately $4.9 billion and $3.7 billion in 2025 for DTE Energy and DTE
Electric, respectively. The Registrants have made certain commitments in connection with the estimated 2025 annual capital expenditures.
Ludington Plant Contract Dispute
DTE Electric and Consumers Energy Company ("Consumers"), joint owners of the Ludington Hydroelectric Pumped Storage plant ("Ludington"), entered into a
2010 engineering, procurement, and construction agreement with Toshiba International Corporation ("TIC"), under which TIC contracted to perform a major overhaul
and upgrade of Ludington. TIC later assigned the contract and all of its obligations to Toshiba America Energy Systems ("TAES"). TAES' work under the contract was
incomplete, defective, and non-conforming. DTE Electric and Consumers documented TAES' failures to perform under the contract and demanded that TAES provide a
comprehensive plan to resolve those matters, including adherence to its warranty commitments and other contractual obligations. DTE Electric and Consumers engaged
in extensive efforts to resolve these issues with TAES, including a formal demand to TAES' parent, Toshiba Corporation, under a parent guaranty it provided. TAES did
not provide a comprehensive plan or otherwise met its performance obligations. As a result of TAES' defaults, DTE Electric and Consumers terminated the contract. In
order to enforce their rights under the contract and parent guaranty, and to pursue appropriate damages, DTE Electric and Consumers filed a complaint against TAES
and Toshiba Corporation in the U.S. District Court for the Eastern District of Michigan in April 2022.
In June 2022, TAES and Toshiba Corporation filed a motion to dismiss the complaint, along with counterclaims seeking approximately $15 million in damages
related to payments allegedly owed under the parties' contract. In September 2022, the motion to dismiss the complaint was denied. DTE Electric believes the
outstanding counterclaims are without merit, but would be liable for 49% of the damages if approved. In October 2022, the combined parties submitted a joint discovery
plan to proceed with the litigation process and a potential trial during the second half of 2025. DTE Electric cannot predict the financial impact or outcome of this
matter.

In May 2023, the MPSC approved a jointly-filed request by DTE Electric and Consumers for authority to defer as a regulatory asset the costs associated with
repairing or replacing the defective work performed by TAES while the litigation with TAES and Toshiba Corporation moves forward. DTE Electric currently estimates
its share of these repair and replacement costs ranges from $350 million to $400 million. Such costs will be offset by any potential litigation proceeds received from
TAES or Toshiba Corporation. DTE Electric and Consumers will have the opportunity to seek recovery and ratemaking treatment for amounts which are not recovered
from TAES or Toshiba Corporation.
Other Contingencies
The Registrants are involved in certain other legal, regulatory, administrative, and environmental proceedings before various courts, arbitration panels, and
governmental agencies concerning claims arising in the ordinary course of business. These proceedings include certain contract disputes, additional environmental
reviews and investigations, audits, inquiries from various regulators, and pending judicial matters. The Registrants cannot predict the final disposition of such
proceedings. The Registrants regularly review legal matters and record provisions for claims that they can estimate and are considered probable of loss. The resolution
of these pending proceedings is not expected to have a material effect on the Registrants' Consolidated Financial Statements in the periods they are resolved.
For a discussion of contingencies related to regulatory matters and derivatives, see Notes 8 and 12 to the Consolidated Financial Statements, "Regulatory Matters"
and "Financial and Other Derivative Instruments," respectively.
NOTE 18 — NUCLEAR OPERATIONS
Property Insurance
DTE Electric maintains property insurance policies specifically for the Fermi 2 plant. These policies cover such items as replacement power and property damage.
NEIL is the primary supplier of the insurance policies.
DTE Electric maintains a policy for extra expenses, including replacement power costs necessitated by Fermi 2’s unavailability due to an insured event. This
policy has a 12-week waiting period and provides an aggregate $490 million of coverage over a three-year period.
DTE Electric has $1.5 billion in primary coverage and $1.25 billion of excess coverage for stabilization, decontamination, debris removal, repair and/or
replacement of property, and decommissioning. The combined coverage limit for total property damage is $2.75 billion. The total limit for property damage for non-
nuclear events is $1.8 billion and an aggregate of $291 million of coverage for extra expenses over a two-year period.
On December 20, 2019, the Terrorism Risk Insurance Program Reauthorization Act of 2019 was signed, extending TRIA through December 31, 2027. For multiple
terrorism losses caused by acts of terrorism not covered under the TRIA occurring within one year after the first loss from terrorism, the NEIL policies would make
available to all insured entities up to $3.2 billion, plus any amounts recovered from reinsurance, government indemnity, or other sources to cover losses.
Under NEIL policies, DTE Electric could be liable for maximum assessments of up to $40 million per event if the loss associated with any one event at any
nuclear plant should exceed the accumulated funds available to NEIL.
Public Liability Insurance
As required by federal law, DTE Electric maintains $500 million of public liability insurance for a nuclear incident. Further, under the Price-Anderson
Amendments Act of 2005, deferred premium charges up to $166 million could be levied against each licensed nuclear facility, but not more than $25 million per year
per facility. Thus, deferred premium charges could be levied against all owners of licensed nuclear facilities in the event of a nuclear incident at any of these facilities.
Nuclear Fuel Disposal Costs
In accordance with the Federal Nuclear Waste Policy Act of 1982, DTE Electric has a contract with the DOE for the future storage and disposal of spent nuclear
fuel from Fermi 2 that required DTE Electric to pay the DOE a fee of 1 mill per kWh of Fermi 2 electricity generated and sold. The fee was a component of nuclear fuel
expense. The 1 mill per kWh DOE fee was reduced to zero effective May 16, 2014.

Table of Contents
DTE Energy Company — DTE Electric Company
Combined Notes to Consolidated Financial Statements — (Continued)
The DOE's Yucca Mountain Nuclear Waste Repository program for the acceptance and disposal of spent nuclear fuel was terminated in 2011. DTE Electric is a
party in the litigation against the DOE for both past and future costs associated with the DOE's failure to accept spent nuclear fuel under the timetable set forth in the
Federal Nuclear Waste Policy Act of 1982. In July 2012, DTE Electric executed a settlement agreement with the federal government for costs associated with the DOE's
delay in acceptance of spent nuclear fuel from Fermi 2 for permanent storage. The settlement agreement, including extensions, has provided for a claims process and
payment of delay-related costs experienced by DTE Electric through 2025. DTE Electric's claims are being settled and paid on a timely basis. The settlement proceeds
reduce the cost of the dry cask storage facility assets and provide reimbursement for related operating expenses.
DTE Electric currently employs a spent nuclear fuel storage strategy utilizing a fuel pool and a dry cask storage facility. The spent nuclear fuel storage strategy is
expected to provide sufficient spent fuel storage capability for the life of the plant as defined by DTE Electric's operating license agreement.
The federal government continues to maintain its legal obligation to accept spent nuclear fuel from Fermi 2 for permanent storage. Issues relating to long-term
waste disposal policy and to the disposition of funds contributed by DTE Electric ratepayers to the federal waste fund await future governmental action.
NOTE 19 — RETIREMENT BENEFITS AND TRUSTEED ASSETS
DTE Energy's subsidiary, DTE Energy Corporate Services, LLC, sponsors defined benefit pension plans and other postretirement benefit plans covering certain
employees of the Registrants. Plan participants of all plans are solely DTE Energy and affiliate participants.

DTE Electric participates in various plans that provide pension and other postretirement benefits for DTE Energy and its affiliates. The plans are primarily
sponsored by the LLC. DTE Electric accounts for its participation in DTE Energy's qualified and non-qualified pension plans by applying multiemployer accounting.
DTE Electric accounts for its participation in other postretirement benefit plans by applying multiple-employer accounting. Within multiemployer and multiple-
employer plans, participants pool plan assets for investment purposes and to reduce the cost of plan administration. The primary difference between plan types is that
assets contributed in multiemployer plans can be used to provide benefits for all participating employers, while assets contributed within a multiple-employer plan are
restricted for use by the contributing employer.

As a result of multiemployer accounting treatment, capitalized costs associated with these plans are reflected in Property, plant, and equipment in DTE Electric's
Consolidated Statements of Financial Position. The same capitalized costs are reflected as Regulatory assets and liabilities in DTE Energy's Consolidated Statements of
Financial Position. For service costs recognized in earnings, these costs have historically been presented in Operation and maintenance in the Registrants' Consolidated
Statements of Operations. For non-service costs recognized in earnings, these costs have historically been presented in Other (Income) and Deductions — Non-
operating retirement benefits, net in DTE Energy's Consolidated Statements of Operations and Operation and maintenance in the DTE Electric Consolidated Statements
of Operations.
In November 2022, DTE Electric received a rate order from the MPSC approving the deferral of qualified pension plan service and non-service costs that were
previously being recognized in earnings. Therefore, the Registrants are recording these costs as Regulatory assets beginning in December 2022.
Pension Plan Benefits
DTE Energy has qualified defined benefit retirement plans for eligible represented and non-represented employees. The plans are noncontributory and provide
traditional retirement benefits based on the employee's years of benefit service, average final compensation, and age at retirement. In addition, certain represented and
non-represented employees are covered under cash balance provisions that determine benefits on annual employer contributions and interest credits. DTE Energy also
maintains supplemental non-qualified, noncontributory, retirement benefit plans for certain management employees. These plans provide for benefits that supplement
those provided by DTE Energy’s other retirement plans.

See Note 8 to the Consolidated Financial Statements, "Regulatory Matters."
The decrease in the pension benefit obligation for the year ended December 31, 2024, was primarily due to an actuarial gain driven by an increase in discount
rates. The increase in DTE Energy's pension benefit obligation in 2023 was primarily due to an actuarial loss driven by a decrease in discount rates.
The Registrants’ policy is to fund pension costs by contributing amounts consistent with the provisions of the Pension Protection Act of 2006, and additional
amounts when it deems appropriate. In 2024, DTE Energy made a nominal contribution to the qualified pension plans. In 2023 and 2022, DTE Gas transferred
$50 million of non-represented qualified pension plan funds to DTE Electric in exchange for cash consideration. In addition, DTE Energy anticipates a transfer of up to
$25 million of non-represented qualified pension plan funds from DTE Gas to DTE Electric in 2025, subject to management discretion and any changes in financial
market conditions.
DTE Energy's subsidiaries are responsible for their share of qualified and non-qualified pension benefit costs. DTE Electric's allocated portion of pension benefit
costs included in regulatory assets and liabilities, operation and maintenance expense, other income and deductions, and capital expenditures were credits of $5 million
and $39 million for the years ended December 31, 2024 and 2023, respectively, and a cost of $101 million for the year ended December 31, 2022. These amounts may
include recognized contractual termination benefit charges, curtailment gains, and settlement charges.

DTE Energy employs a formal process in determining the long-term rate of return for various asset classes. Management reviews historic financial market risks
and returns and long-term historic relationships between the asset classes of equities, fixed income, and other assets, consistent with the widely accepted capital market
principle that asset classes with higher volatility generate a greater return over the long-term. Current market factors such as inflation, interest rates, asset class risks, and
asset class returns are evaluated and considered before long-term capital market assumptions are determined. The long-term portfolio return is also established
employing a consistent formal process, with due consideration of diversification, active investment management, and rebalancing. Peer data is reviewed to check for
reasonableness. As a result of this process, the Registrants have a long-term rate of return assumption for the pension plans of 7.80% for 2025. The Registrants believe
this rate is a reasonable assumption for the long-term rate of return on plan assets given the current investment strategy.
The DTE Energy Company Affiliates Employee Benefit Plans Master Trust employs a liability driven investment program whereby the characteristics of plan
liabilities are considered when determining investment policy. Risk tolerance is established through consideration of future plan cash flows, plan funded status, and
corporate financial considerations. The investment portfolio contains a diversified blend of equity, fixed income, and other investments. Furthermore, equity investments
are diversified across U.S. and non-U.S. stocks and large and small market capitalizations. Fixed income investments generally include U.S. Treasuries, other
governmental debt, diversified corporate bonds, bank loans, and mortgage-backed securities. Other investments are used to enhance long-term returns while improving
portfolio diversification. Derivatives may be utilized in a risk controlled manner, to potentially increase the portfolio beyond the market value of invested assets and/or
reduce portfolio investment risk. Investment risk is measured and monitored on an ongoing basis through annual liability measurements, periodic asset/liability studies,
and quarterly investment portfolio reviews.

Other Postretirement Benefits
The Registrants participate in defined benefit plans sponsored by the LLC that provide certain other postretirement health care and life insurance benefits for
employees who are eligible for these benefits. The Registrants' policy is to fund certain trusts to meet its other postretirement benefit obligations. DTE Energy did not
make any contributions to these trusts during 2024 and does not anticipate making any contributions to the trusts in 2025.
DTE Energy and DTE Electric offer a defined contribution VEBA for eligible represented and non-represented employees, in lieu of defined benefit post-
employment health care benefits. The Registrants allocate a fixed amount per year to an account in a defined contribution VEBA for each employee. These accounts are
managed either by the Registrant (for non-represented and certain represented groups) or by the Utility Workers of America for Local 223 employees. The following

The Registrants' postretirement benefit obligations decreased for the year ended December 31, 2024 primarily due to actuarial gains driven by increases in
discount rates. The postretirement benefit obligation did not change significantly for year ended December 31, 2023.

The process used in determining the long-term rate of return on assets for the other postretirement benefit plans is similar to that previously described for the
pension plans. As a result of this process, the Registrants have a long-term rate of return assumption for the other postretirement benefit plans of 7.50% for 2025. The
Registrants believe this rate is a reasonable assumption for the long-term rate of return on plan assets given the current investment strategy.
The DTE Energy Company Master VEBA Trust employs a liability driven investment program whereby the characteristics of plan liabilities are considered when
determining investment policy. Risk tolerance is established through consideration of future plan cash flows, plan funded status, and corporate financial considerations.
The investment portfolio contains a diversified blend of equity, fixed income, and other investments. Furthermore, equity investments are diversified across U.S. and
non-U.S. stocks and large and small market capitalizations. Fixed income investments generally include U.S. Treasuries, other governmental debt, diversified corporate
bonds, bank loans, and mortgage-backed securities. Other investments are used to enhance long-term returns while improving portfolio diversification. Derivatives may
be utilized in a risk controlled manner to potentially increase the portfolio beyond the market value of invested assets and/or reduce portfolio investment risk.
Investment risk is measured and monitored on an ongoing basis through annual liability measurements, periodic asset/liability studies, and quarterly investment
portfolio reviews.

The DTE Energy Company Master VEBA Trust holds debt and equity securities directly and indirectly through commingled funds. Exchange-traded debt and
equity securities held directly, as well as publicly traded commingled funds, are valued using quoted market prices in actively traded markets. Non-publicly traded
commingled funds hold exchange-traded equity or debt securities and are valued based on NAVs. Non-exchange traded fixed income securities are valued by the trustee
based upon quotations available from brokers or pricing services. A primary price source is identified by asset type, class, or issue for each security. The trustee monitors
prices supplied by pricing services and may use a supplemental price source or change the primary price source of a given security if the trustee challenges an assigned
price and determines that another price source is considered preferable. The Registrants have obtained an understanding of how these prices are derived, including the
nature and observability of the inputs used in deriving such prices.
Defined Contribution Plans
The Registrants also sponsor defined contribution retirement savings plans. Participation in one of these plans is available to substantially all represented and non-
represented employees. For substantially all employees, the Registrants match employee contributions up to certain predefined limits based upon eligible compensation
and the employee’s contribution rate. Additionally, for eligible represented and non-represented employees who do not participate in the Pension Plans, the Registrants
contribute amounts equivalent to 4% (8% for certain DTE Gas represented employees) of an employee's eligible compensation to the employee's defined contribution
retirement savings plan. For DTE Energy, the cost of these plans was $76 million, $75 million, and $73 million for the years ended December 31, 2024, 2023, and 2022,
respectively. For DTE Electric, the cost of these plans was $35 million for the years ended December 31, 2024, 2023 and 2022.
NOTE 20 — STOCK-BASED COMPENSATION
DTE Energy’s stock incentive program permits the grant of incentive stock options, non-qualifying stock options, stock awards, performance shares, and
performance units to employees and members of its Board of Directors. As a result of a stock award, a settlement of an award of performance shares, or by exercise of a
participant’s stock option, DTE Energy may deliver common stock from its authorized but unissued common stock and/or from outstanding common stock acquired by
or on behalf of DTE Energy in the name of the participant. Key provisions of the stock incentive program are:
•
Authorized limit is 20,162,716 shares of common stock;
•
Prohibits the grant of a stock option with an exercise price that is less than the fair market value of DTE Energy’s stock on the date of the grant; and
•
Imposes the following award limits to a single participant in a single calendar year, (1) options for more than 500,000 shares of common stock; (2) stock
awards for more than 150,000 shares of common stock; (3) performance share awards for more than 300,000 shares of common stock (based on the
maximum payout under the award); or (4) more than 1,000,000 performance units, which have a face amount of $1.00 each.
DTE Energy records compensation expense at fair value over the vesting period for all awards it grants.

Restricted Stock Awards
Stock awards granted under the plan are restricted for varying periods, generally for three years. Participants have all rights of a shareholder with respect to a stock
award, including the right to receive dividends and vote the shares. Prior to vesting in stock awards, the participant: (i) may not sell, transfer, pledge, exchange, or
otherwise dispose of shares; (ii) shall not retain custody of the share certificates; and (iii) will deliver to DTE Energy a stock power with respect to each stock award
upon request.

Table of Contents
DTE Energy Company — DTE Electric Company
Combined Notes to Consolidated Financial Statements — (Continued)
The stock awards are recorded at cost that approximates fair value on the date of grant. The cost is amortized to compensation expense over the vesting period.
The fair value of awards vested were not material for the years ended December 31, 2024, 2023, and 2022. Compensation cost charged against income was $14
million for the years ended December 31, 2024 and 2023, and $15 million for the year ended December 31, 2022.
Performance Share Awards
Performance shares awarded under the plan are for a specified number of shares of DTE Energy common stock that entitle the holder to receive a cash payment,
shares of DTE Energy common stock, or a combination thereof. The final value of the award is determined by the achievement of certain performance objectives and
market conditions. The awards vest at the end of a specified period, usually three years. Awards granted in 2024, 2023, and 2022 were primarily deemed to be equity
awards. The DTE Energy stock price and number of probable shares attributable to market conditions for such equity awards are fair valued only at the grant date. DTE
Energy accounts for performance share awards by accruing compensation expense over the vesting period based on: (i) the number of shares expected to be paid which
is based on the probable achievement of performance objectives; and (ii) the closing stock price market value. The settlement of the award is based on the closing price
at the settlement date.

Sum of awards settled in cash and stock approximates the intrinsic value of the awards.
During the vesting period, the recipient of a performance share award has no shareholder rights. During the period beginning on the date the performance shares
are awarded and ending on the certification date of the performance objectives, the number of performance shares awarded will be increased, assuming full dividend
reinvestment at the fair market value on the dividend payment date. The cumulative number of performance shares will be adjusted to determine the final payment based
on the performance objectives achieved. Performance share awards are nontransferable and are subject to risk of forfeiture.

Company Supplemental Savings Plan (Amended and Restated Effective January 1, 2005) (the “Plan”) is amended as follows, effective as of
the January 1, 2025:
1. Section 2.3 of the Plan is added to read as follow:
2.3 Payment Period. “Payment Period” means after January 1 and no later than March 1 of the Plan Year.

(2) other management or highly compensated Employees as shall be
approved by the Chief Executive Officer of an Employer that has adopted the Plan
whose Before-Tax Contributions (including Roth Contributions and Catch-Up Contributions, if applicable), Matching Contributions,
or Employer Contributions under the Qualified Plan are limited because of the limitation on compensation under Section 401(a)(17)
of the Code, the limitation on elective deferrals under Section 402(g) of the Code, the limitation on catch-up contributions under
Section 414(v) of the Code (if applicable), the limitation on benefits and contributions under Section 415 of the Code, or any other
provision of the Code or other law that the Committee hereafter designates.
4. Section 4.2(a) of the Plan is replaced with the following:
(a)    An amount equal to the difference between (1) and (2) below:

Exhibit 10.2
(1) the amount that the Participant would have contributed to the Qualified Plan as Before-Tax Contributions
(including Roth Contributions and Catch-Up Contributions, if applicable) for the pay period if the Before-Tax
Contributions (including Roth Contributions and Catch-up Contributions, if applicable) by the Participant under the
Qualified Plan were not limited by the application of any restrictions in Section 3.1(a) or any provision of the
Qualified Plan relating to the limitations in Section 3.1(a);
(2)    the amount that the Participant actually contributed to the
Qualified Plan as Before-Tax Contributions (including Roth Contributions and Catch-Up Contributions, if applicable)
for the pay period.
5.    Section 4.2(b)(1) of the Plan is replaced with the following:
(1) the amount that the Employer of the Participant would have contributed to the Qualified Plan as Matching Contributions on
behalf of the Participant for the pay period if the Participant had contributed to the Qualified Plan the amount set forth in Section
4.2(a)(1) during the pay period plus any After-Tax Contributions actually contributed to the Qualified Plan by the Participant during
the pay period;
6.    Section 6.1(b) of the Plan is replaced with the following:
(b) Post-2004 Account. On the date that a Participant incurs a Separation from Service other than because of death, the Participant
shall be entitled to receive the amount credited to his or her Post-2004 Account in the Plan. All Post-2004 Accounts under this Plan
are 100% vested, subject to adjustment for hypothetical earnings and losses.
(1)    If the Participant is not a “specified employee” for purposes of Code
section 409A at the time the Participant incurs a Separation from Service for any reason other than death, a lump sum
distribution or the first annual installment of the Participant’s Post-2004 Account shall be made:
(A) During the Payment Period following the end of the Plan Year in which the Participant incurs a Separation from
Service, if the Participant did not make any election under Section 6.2(b)(2); or
(B) During the Payment Period coincident with or next following the latest date to which distribution was deferred by
an election under Section 6.2(b)(2), if the Participant made one or more elections under Section 6.2(b)(2); and
(2) If a Participant is a “specified employee” for purposes of Code section 409A at the time the Participant incurs a
Separation from Service for any reason other than death, a lump sum distribution or first annual

Exhibit 10.2
installment of the Participant’s Post-2004 Account will not be made before the latest of:    
(A) During the Payment Period following the end of the Plan Year in which the Participant incurs a Separation from
Service, if the Participant did not make any election under Section 6.2(b)(2); and
(B) During the Payment Period coincident with or next following the latest date to which distribution was deferred by
an election under section 6.2(b)(2), if the Participant made one or more elections under Section 6.2(b)(2); and
(C) the earlier of:
(i) the first day of the calendar month beginning more than 6 months after the date of the Participant’s
Separation from Service; and
(ii) the first day of the calendar month beginning after the Participant’s death.
Subsequent annual installments of the Participant’s Post-2004 Benefit shall be made each following Payment Period of the
installment period.
A Participant may elect to have the Participant’s Post-2004 Account paid in annual payments over a period of not less than two years
and not more than 15 years, or in one lump sum, by making an election within 30 days of the date the Participant is first formally
notified of his or her eligibility to participate in the Plan and receive credits under either Section 4.2(a) or Section 4.2(c). If a
Participant does not elect a form of payment for the Participant’s Post-2004 Account within 30 days of the Participant’s initial
eligibility, the Participant’s entire Post-2004 Account will be paid in one lump sum. Any election by the Participant after December
31, 2008 regarding the form in which the Participant’s Post-2004 Account will be distributed will apply to the Participant’s entire
Post-2004 Account and is subject to the restrictions imposed by Section 6.2 on changes to elections of timing or form of
distributions.
In addition, if a Participant’s Post-2004 Account is less than or equal to the dollar limit under Code Section 402(g) for the calendar
year in which the Participant incurs a Separation from Service, the Participant’s Post-2004 Account shall be paid in one lump sum to
the extent permitted by Code Section 409A and the related Treasury Regulations.
Payment of a Participant’s Post-2004 Account due to a Participant’s death is governed by Section 7.3.

Exhibit 10.2
7. Section 6.1(c)(1) of the Plan is replaced with the following:
(1) General Rule. The amount of the annual payments shall be calculated to be paid out over the specified period, based on the entire
balance in the Participant’s hypothetical bookkeeping account as of his or her Termination Date (for Pre-2005 Accounts) or
Separation from Service date (for Post-2004 Accounts). Earnings and losses based on the hypothetical bookkeeping account
investments shall be credited to the Participant’s hypothetical bookkeeping account through December 31 of each Plan Year in which
the Participant has a balance in such hypothetical bookkeeping account. The distribution to a Participant shall be paid in cash. Except
as provided in Section 6.1(c)(2), the initial distribution shall be determined by dividing the value of the Participant’s account
determined as of December 31 of the Plan Year in which the Participant's employment terminated (for Pre-2005 Accounts) or the
Participant incurs a Separation from Service (for Post-2004 Accounts), by the number of installment payments to be made. The
amount distributed to the Participant thereafter shall be recalculated each year to reflect changes in the hypothetical bookkeeping
account balance through December 31 of such subsequent calendar year and the remaining number of installment payments to be
made.
8. Section 6.2(b)(2)(A)(i) of the Plan is replaced with the following:
(i) For purposes of this Section 6.2(b)(2)(A), the date the Participant incurs a Separation from Service other than because of death is
treated as “the earliest date on which distribution of the Post-2004 Account would begin” if the Participant has not filed a previous
election under this Section 6.2(b)(2) to change the form of distribution of the Post-2004 Account; and

Exhibit 19.1
DTE Energy Policy
GV15 Insider Trading Policy
February 4, 2025
1. Applicability
This policy applies to all members of the Board of Directors (“Directors”), officers and employees of DTE Energy Company (“Company”) and its subsidiaries,
together with any agents or advisors to the Company.
2. Policy
A. General
1.
If a Director, officer, employee, agent or advisor of the Company has material, nonpublic information relating to the Company, that person is an
“insider” with respect to that information, and neither that person nor any of his or her Related Persons (as defined below) may buy, sell or otherwise
trade securities of the Company, including common stock, bonds and other debt securities, convertible debentures and warrants, or any derivative of the
foregoing (“Company Securities”).
2.
This Policy also applies to material, nonpublic information relating to any other company with publicly-traded securities, including our customers or
suppliers, obtained in the course of employment by or association with DTE Energy.
3.
No person possessing material, nonpublic information may engage in any other action to take advantage of, or pass on to others, that information.
4.
Information is considered “material” if there is a substantial likelihood that a reasonable investor would consider it important in making a decision to
buy, sell or hold a security, or where the information is likely to affect the market price of the security.
5.
Material information can be positive or negative, and can relate to virtually any aspect of the Company’s business or to any type of Company Security
(i.e., debt or equity). Some examples of material information may include:
•
Unpublished financial or operational results or projections, including earnings information
•
Pending or proposed mergers, acquisitions, dispositions or other transactions
•
Significant changes in corporate objectives
•
Significant sale of assets
•
Changes in dividend or stock repurchase policies
•
Financial liquidity problems
•
Cybersecurity risks and incidents, including vulnerabilities and breaches.
6.    The above list is only illustrative; many other types of information may be considered “material,” depending on the circumstances. If you are unsure
whether particular nonpublic information is material, you should presume that it is material and consult with the Office of the General Counsel before
disclosing such information or trading in any securities of a company to which such information relates.
7.    Information is “nonpublic” if it is not available to the general public. In order for information to be considered public, it must have been disclosed in the
Company’s SEC filings or widely disseminated in a manner making it generally available to investors, such as through a public press release, and
enough time must have passed to allow the public to digest the information.
8.    After the Company has publicly announced material information, no person may trade in Company Securities until two full trading days have elapsed
after an announcement. For example, if the information is publicly announced before the market opens on Monday, trading could begin at the opening
of trading on the following Wednesday, and if the information is publicly announced after the market closes on Monday, trading could begin at the
opening of trading on the following Thursday.

Exhibit 19.1
9.    For purposes of this Policy, a “Related Person” includes the spouse, minor children, or anyone else living in an insider’s household; any other person
whose transactions in Company Securities are subject to the insider’s direct or indirect influence or control; partnerships in which an insider is a general
partner; trusts of which an insider is a trustee; estates of which an insider is an executor; and any other legal entities controlled by an insider.
10.    Insiders may be liable for communicating, recommending or “tipping” material, nonpublic information to any third party (a “tippee”), regardless of
whether the tippee is a Related Person.
11.    Further, insider trading violations are not limited to trading or tipping by insiders. Persons other than insiders also can be liable for insider trading,
including tippees who trade on material, nonpublic information tipped to them and individuals who trade on material, nonpublic information which has
been misappropriated.
B. Additional Restrictions and Requirements for Directors, Officers, and Certain Other Employees
1.
In addition to being subject to all of the other limitations in this Policy, Directors and officers are prohibited from trading Company Securities during
defined quarterly blackout periods, regardless of whether they possess material, nonpublic information. Additional employees (“designated
employees”) may also be notified by their leaders that they are prohibited from trading during quarterly blackout periods.
2.
Each quarterly blackout period begins at market closing on the date that is one trading day prior to the release of the Company’s “flash report” for the
second month of the quarter (typically released on or about the 7th working day of the third month of the quarter). The quarterly blackout period
usually ends at market closing on the second full day of trading following the release of the Company’s quarterly earnings. The Corporate Secretary
will publish the exact dates of quarterly blackout periods. During these quarterly blackout periods, directors, officers and other designated employees
generally possess or are presumed to possess material, nonpublic information about the Company’s financial results.
3.
From time to time, special blackout periods may be declared for persons with certain specific material, nonpublic information regarding the Company
(such as negotiation of mergers, acquisitions or dispositions or other developments). The affected persons must keep the existence of any special
blackout period confidential.
4.
Open trading windows are not “safe harbors” that ensure compliance with securities laws. Insiders remain responsible for their trades and should use
good judgment at all times, never transacting while in possession of material, nonpublic information.
5.
Directors, officers and other employees subject to blackout periods as described above are prohibited, at all times, from instituting trading plans under
Rule 10b5-1 under the Securities Exchange Act of 1934.
6.
Each Director and officer (and their Related Persons) must always obtain prior clearance from the Corporate Secretary before making any purchase,
sale or gift of Company Securities, including any exercise of stock options or any transfer between the Company’s Common Stock Fund and other
investment options in the Company’s retirement and excess benefit plans.
7.
Each officer or Director of the Company who is subject to a stock ownership requirement is prohibited from selling Company securities acquired upon
the vesting of stock awards and exercise of stock options unless he or she is in compliance with such stock ownership requirement.
C. Transactions under Company-sponsored Plans
1.
This Policy’s trading restrictions apply to any market sale, gift, or other disposition of Company Securities received following the vesting of any
restricted stock, performance shares, or other awards received under any of the Company’s long-term incentive plans, but do not apply to the
withholding of taxes in connection with the vesting or delivery of Company Securities underlying such awards.
2.
This Policy’s trading restrictions apply to elections participants may make under the Company’s savings and deferral plans that relate to Company
Securities, including elections with respect to the

Exhibit 19.1
investment of contributions, intra-plan transfers of an existing account balance between investment funds, loans, and distributions, but do not apply to a
participant’s periodic contribution of money to such plans pursuant to payroll deduction elections.
