*The [added: 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 [added: clean and] renewable energy.

In addition, the Registrants expect to comply with new Michigan legislation increasing the percentage of power required to be provided by [added: clean energy resources and] renewable energy sources.

Nuclear PTCs are separately recorded in Income Tax Expense (Benefit) with an offsetting reduction to revenue for recoverable power supply costs as tax savings are passed on to customers.

The decrease in 2023 was primarily due to unfavorable weather compared to 2022.

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).

| | | | 2024 | | | | | | 2023 | | |

| Midstream storage and transportation revenues | | | 10 | | | | | | 3 | | |

The increase in 2024 was primarily due to the write-off of capital expenditures, of which $3 million was disallowed by the MPSC in the November 2024 rate order.

The increase in 2024 was primarily due to higher net interest expense of $14 million.

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 increase in 2024 was primarily due to new projects in the Renewables business.

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 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 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 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.

On July 1, 2021, DTE Energy completed the separation of DT Midstream, its former natural gas pipeline, storage, and gathering non-utility business.

Financial results of DT Midstream are presented as discontinued operations in the Consolidated Financial Statements.

Voluntary Separation Incentive Program

In January 2024, DTE Energy announced a voluntary separation incentive program ("VSIP") for certain non-represented employees within the electric and gas utilities and corporate support organizations.

Under the program, employees can elect a benefits and compensation package and exit the company to retire or pursue other opportunities.

DTE Energy currently expects the VSIP to result in approximately $40 to $50 million of one-time costs in the first half of 2024, primarily in the first quarter.

The costs will be allocated to Operation and maintenance expense primarily at the Electric and Gas segments.

Actual costs may differ from current estimates as elections under the VSIP are finalized.

For the remainder of 2024, cost savings from the VSIP are expected to offset a portion of the one-time costs incurred early in the year.

Over the long-term, cost savings from the VSIP will support DTE Energy's goals for customer affordability.

(a)Represents deliveries for self-generators that have purchased power from alternative energy suppliers to supplement their power requirements.

The decrease in 2022 was primarily due to a decrease in residential sales as customers resumed more pre-pandemic activities and worked less from their homes.

There were no such disallowances in 2021.

The increase in 2022 was primarily due to higher net interest expense of $27 million and an unfavorable change in investment earnings of $19 million, partially offset by lower non-operating retirement benefits expense of $37 million and a $4 million decrease in non-operational costs that ceased with the retirement of a power plant.

| Voluntary refund | | | 10 | | | | | | (5) | | |

The decrease in 2022 was primarily due to capital write-offs of $4 million in 2021.

The activity in 2023 included higher net interest expense of $10 million that was offset by a favorable change in investment earnings of $10 million.

The increase in 2022 was primarily due to higher earnings and lower amortization of the TCJA regulatory liability.

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 reflects 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 is 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.

A final MPSC order in this case is expected in November 2024.

DTE Vantage formerly included projects that produced reduced emissions fuel; however, these projects were closed as planned in 2022 upon REF facilities exhausting their eligibility for generating production tax credits.
