The bill authorizes community solar programs, modifies existing restrictions on energy systems, and introduces new definitions and requirements for solar facilities.

  • 66.0401(1m)

    No → Except as provided in sub. (1s), no

    This change allows for specific exceptions to the restrictions on solar energy systems.

  • 76.28(1)(e)(intro.)

    except electric cooperatives taxed under s. 76.48 → except electric cooperatives taxed under s. 76.48 and subscriber organizations, as defined in s. 196.376 (1) (i),

    This adds subscriber organizations to the definition of light, heat, and power companies, clarifying their status under the law.

  • 196.01(5)(b) 9.

    A subscriber organization, as defined in s. 196.376 (1) (i), if, besides owning or operating a community solar facility, the subscriber organization does not otherwise directly or indirectly provide electricity to the public.

    This creates a new definition for subscriber organizations, specifying their operation within community solar facilities.

  • 66.0401(1e)(bd)

    "Community solar facility" has the meaning given in s. 196.376 (1) (b).

    This establishes a new definition for community solar facilities.

  • 66.0401(1e)(bm)

(a) Notwithstanding ss. 60.61, 60.62, 61.35, and 62.23 (7), no building permit for a structure that is part of a community solar facility may be issued unless the municipality with zoning authority over the parcels on which the community solar facility is to be located approves the use of those parcels for purposes of a community solar facility by a two-thirds vote of the governing body of the municipality.

    This creates regulatory requirements for obtaining building permits for community solar facilities.

  • 196.376

    Community solar programs. (1) D EFINITION. (a) "Bill credit" means the kilowatt-hours generated by the community solar facility allocated to a subscriber to offset the kilowatt-hour usage on the subscriber’s electricity bill.
