Exit Activities: In accordance with its Clean Energy Plan, Consumers retired the D.E. Karn coal-fueled electric generating units in June 2023 and plans to retire the J.H. Campbell coal-fueled generating units in 2025. In order to ensure necessary staffing at both D.E. Karn and J.H. Campbell through retirement, Consumers has implemented retention incentive programs. The aggregate cost of the D.E. Karn program, which is now complete, was $32 million. The aggregate cost of the J.H. Campbell program through 2025 is estimated to be $50 million. The MPSC has approved deferred accounting treatment for these costs; these expenses are deferred as a regulatory asset.
As of December 31, 2023, the cumulative cost incurred and charged to maintenance and other operating expenses related to the D.E. Karn retention incentive program was $16 million. Additionally, an amount of $4 million was capitalized as a cost of plant, property, and equipment and an amount of $12 million was deferred as a regulatory asset. The cumulative cost incurred and deferred as a regulatory asset related to the J.H. Campbell retention incentive program was $35 million. The regulatory assets for both programs will be collected from customers over three years.
