Detailed Narrative
Economic Development & Data Center Growth
The company is experiencing significant economic development in its service territory, particularly driven by large data center projects. Microsoft is expanding its Mount Pleasant complex with a second phase, representing an incremental $4 billion investment. Vantage Data Centers' Lighthouse campus in Port Washington, part of the OpenAI and Oracle Stargate expansion, is projected to reach 3.5 GW of demand over time⏳, with 1.3 GW expected in the next five years and an initial $15 billion investment. This growth is fostering broader commercial and residential development, with Wisconsin's unemployment rate remaining low at 3.1%.
Expanded Capital Plan
WEC Energy Group announced a new 5-year capital plan (2026-2030) totaling $36.5 billion, an $8.5 billion increase (over 30%) from the previous plan. This plan is designed to support the robust load growth and is expected to drive asset-based growth at an average rate of 11.3% annually. The increase is primarily allocated to regulated electric generation, transmission, distribution in Wisconsin, and the pipe retirement program in Illinois.
Generation Strategy
The capital plan includes an "all-of-the-above" approach for generation, with an incremental $3.4 billion investment in modern natural gas generation (combustion turbines, reciprocating internal combustion engines, upgrades) and a $2.5 billion increase in renewable generation and battery storage investments. This strategy emphasizes dispatchable resources for reliability.
Transmission & Distribution Investments
American Transmission Company (ATC) projects will receive approximately $4.1 billion, a $900 million increase, to enhance transmission capabilities, connect new generation, and serve data center needs. An additional $2 billion is allocated to electric and natural gas distribution networks, including significant investment in the Chicago pipe retirement program to replace over 1,000 miles of cast iron and ductile iron pipe by 2035.
Regulatory Updates
In Wisconsin, the proposed Very Large Customer (VLC) tariff, designed to meet large customer needs while protecting others, is under review by the Public Service Commission. It proposes a fixed ROE of 10.48%-10.98% and a 57% equity ratio, with an order expected by early May next year. In Illinois, the company continues to coordinate on the pipe retirement program and plans to file a general rate case in early 2026 for test year 2027.
Financing Plan
The expanded capital plan will be funded with approximately $21 billion from cash from operations, $14 billion from incremental debt, and $4.8 billion to $5.2 billion from common equity over the next five years. The company expects any incremental capital to be funded with 50% equity content, split between common equity and hybrid/like-kind securities. For 2026, common equity issuances are projected to be between $900 million and $1.1 billion.
