WI SB559

Retail electric customers of investor-owned utilities may subscribe to community solar facilities and receive bill credits for electricity produced, with subscribers and facilities required to be in the same utility service territory

Total statewide community solar capacity is capped at 1,750 megawatts, apportioned among investor-owned utilities based on their share of total electric load served in Wisconsin

Community solar facilities are limited to 5 megawatts (or 20 megawatts on rooftops/previously developed sites), must have at least 3 subscribers, and no single subscriber may hold more than 40% interest in output

Municipalities with zoning authority must approve community solar facility sites by a two-thirds vote of the governing body before building permits can be issued

Public Service Commission must promulgate rules within 13 months, including requirements that bill credits cannot reduce monthly bills below $20, facilities placed in service after December 31, 2035 are prohibited from enrolling, and subscriber organizations must maintain decommissioning funds
