Strategic Initiatives
Growth programs, investments, and their expected impact
A comprehensive plan to transition the generation fleet away from coal. WEC plans to use coal only as a backup fuel by the end of 2030 and completely eliminate it as an energy source by the end of 2032 [1.3.1]. The initiative is supported by $12.6 billion in planned renewable investments between 2026 and 2030 to add 6,500 MW of solar, wind, and battery storage.
Expected impact: Achieving net-carbon neutrality in the electric generation fleet by 2050, while significantly reducing near-term emissions and modernizing the asset base.
Expanding power infrastructure to support massive data center developments in southeastern Wisconsin, notably by Microsoft and Vantage Data Centers. WEC is utilizing a newly approved 'Very Large Customer' (VLC) tariff in Wisconsin, which secures dedicated generation resources and fixed ROE/equity terms to protect existing retail customers.
Expected impact: Serving an expected 3.9 GW of new demand by 2030, driving a projected 6% to 8% compound annual growth in retail electric sales.
Investing in modern, efficient natural gas generation, reciprocating internal combustion engines (RICE), and liquefied natural gas (LNG) storage to ensure grid reliability and fuel flexibility during peak winter heating periods.
Expected impact: Securing essential baseload and peaking capacity to support the integration of intermittent renewable energy resources.
