SB 559 Wisconsin Senate · 2025-2026 Regular Session

Relating to: authorizing community solar programs and granting rule-making authority. (FE)

SB 559 authorizes community solar programs in Wisconsin, allowing multiple households or businesses to subscribe to shared solar energy projects. It requires municipalities to approve community solar facility locations with a two-thirds vote of their governing body (with limited exceptions), while ensuring facilities comply with zoning rules. The bill defines key terms like "community solar facility" (ground-mounted or rooftop projects generating electricity for subscribers), sets size limits (max 5MW for ground sites, 20MW for rooftop sites), and requires at least 3 subscribers with 60% of capacity coming from small subscriptions (≤40 kW). Subscribers receive bill credits for the electricity their subscription generates, offsetting their energy costs through the utility.
