WEC plans approximately $2.9 billion of battery-energy-storage investments from 2026 through 2030 to capture excess power and release it during peak demand or weather-related and other unexpected disruptions. The PSCW approved WE's proposed LNG facility at the OCPP site with two Bcf of storage, while additional Wisconsin LNG facilities under the capital plan could provide approximately four Bcf of additional supply. In Illinois, the ICC's February 2025 order directed PGL to focus on retiring all cast- and ductile-iron pipes smaller than 36 inches by January 1, 2035 through its PRP. WEC expects to spend approximately $7.1 billion on natural-gas distribution reliability and $4.7 billion on electric distribution reliability from 2026 to 2030.
