 56 MWs of battery storage. The construction of the solar portion and battery storage is expected to be completed in 2025 and 2026, respectively.

Natural Gas-Fired Generation

In May 2024, we completed the acquisition of an additional 100 MWs of West Riverside's nameplate capacity, in the second of two option exercises. West Riverside is a commercially operational dual fueled combined cycle generation facility in Beloit, Wisconsin, and is operated by an unaffiliated utility. See Note 2, Acquisitions, for more information. 

In April 2024, we filed requests with the PSCW for the following projects:

•Adding seven natural gas-fired RICE units near the Paris Generating Station. The new RICE units would be fueled with natural gas and capable of producing approximately 128 MWs.

•Building five natural gas-fired combustion turbines capable of producing approximately 1,100 MWs which would be located at the existing OCPP site.

Electric System Reliability

The PSCW requires us to maintain a planning reserve margin above our projected annual peak demand forecast to help ensure reliability of electric service to our customers. These planning reserve requirements are consistent with the MISO calculated planning reserve margin. In 2008, the PSCW established a 14.5% reserve margin requirement for long-term planning (planning years two through ten). For short-term planning (planning year one), the PSCW requires Wisconsin utilities to follow the planning reserve margin established by MISO. MISO implemented seasonal requirements effective June 1, 2023. The installed capacity reserve margins for the planning year June 1, 2024 through May 31, 2025 are as follows: 17.7% summer (June – August); 25.2% fall (September – November); 49.4% winter (December – February); and 40.8% spring (March – May). MISO's short-term reserve margin requirements experience year-to-year and season-to-season fluctuations, primarily due to changes in the generation resource mix and average forced outage rate of generation within the MISO footprint.

We believe that we have adequate capacity through company-owned generation units, leased generating units, and power purchase contracts to meet the MISO calculated planning reserve margin during the current planning year. We also fully anticipate that we will have adequate capacity to meet the planning reserve margin requirements for the upcoming planning year.
