Energy (Solar)

AB 493 authorizes community solar programs where multiple households share power generated from a single solar facility. It requires municipalities to approve new community solar projects with a two-thirds vote of their governing body (unless zoning allows it automatically), limits facility size to 5 megawatts (or 20 megawatts on previously developed sites like parking lots), and ensures no single subscriber controls more than 40% of the facility’s output. This directly affects local governments (through zoning rules), solar developers ("subscriber organizations"), and residents who join these programs. The bill defines key terms like "community solar facility" and "subscriber" to standardize program rules and interconnection with utilities.

AB 174 amends energy statutes to redefine "renewable resources" for reporting purposes, explicitly including nuclear energy starting in 2026. It establishes new definitions for large-scale wind/solar systems (100+ megawatts) and battery storage, while clarifying that local governments cannot restrict energy installations more strictly than state rules. The bill affects energy developers, utilities, and local governments by changing how transmission contracts are audited and how renewable/nuclear projects are categorized. It does not create new project requirements but updates existing reporting frameworks for the state legislature and governor. The bill is pending in the Energy and Utilities Committee after being introduced in April 2025.

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.

SB 3 requires local governments to approve certain wind and solar energy projects before the Public Service Commission can review them. This directly affects renewable energy developers seeking to build projects and local municipalities responsible for granting permits. The bill creates a new step where community-level approval must be secured prior to state-level review by the Public Service Commission. This changes the current process by adding a mandatory local consent requirement before state agencies can act on these projects.

AB 7 requires local governments (cities, villages, or towns) to approve large-scale wind and solar projects (15 megawatts or more) before the Public Service Commission can approve them. Developers must seek municipal approval, which must be granted or denied within 90 days (with possible 90-day extensions for specific reasons). If a municipality fails to act within the deadline, the project is automatically approved. This bill directly affects renewable energy developers and local governments, shifting approval authority to municipalities for qualifying projects.
