WEC Energy Group

What WEC Energy Group does

WEC Energy Group Inc. is a Milwaukee-based regulated utility holding company that operates electric generation and distribution and natural gas delivery businesses across Wisconsin, Illinois, Michigan, and Minnesota, serving approximately 4.7 million customers through wholly-owned subsidiaries including We Energies, Wisconsin Public Service, Peoples Gas, North Shore Gas, Minnesota Energy Resources, Michigan Gas Utilities, and Upper Michigan Energy Resources. The company owns and operates 8,375 megawatts of generating capacity, 72,800 miles of electric distribution lines, and 48,500 miles of natural gas distribution and transmission lines, with a generation mix spanning coal (to be eliminated by 2032), natural gas, nuclear, renewables, and emerging hydrogen blending capability.

The company's core technology stack centers on regulated utility infrastructure, supplemented by a renewable portfolio of more than 2,600 megawatts of wind and solar capacity held through WEC Infrastructure LLC, plus solar and battery storage projects in development. A hydrogen blending pilot completed in October 2022 with EPRI demonstrated 25% hydrogen blending in an 18-MW reciprocating engine unit at Upper Michigan Energy Resources, supporting the company's net-zero carbon emissions goal by 2050.

WEC earns revenue through regulated rate base returns approved by state Public Service Commissions across its four-state footprint, with residential and small commercial customers paying monthly tariffs. A newly approved Very Large Customer (VLC) tariff enables long-term (15-year minimum) direct service to hyperscale data center customers above 100 MW, with customers required to cover 100% of generation and grid infrastructure costs. The company's growth is anchored by 3.9 GW of contracted data center load through 2030, including Microsoft's 2.6 GW I-94 corridor buildout and Vantage Data Centers' 1.3 GW Lighthouse campus in Port Washington serving Oracle and OpenAI. Management projects Wisconsin electric sales growth of 45% between 2026 and 2030, supported by a $37.5 billion five-year capital plan that is the largest in company history.
