Regulatory Matters | REGULATORY MATTERS 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 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. 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. A final MPSC order in this case is expected in January 2025.
