SB 556 Wisconsin Senate · 2025-2026 Regular Session

Relating to: providing utility aid payments for certain energy storage facilities. (FE)

SB 556 creates new annual payments to municipalities and counties for hosting energy storage facilities (like batteries or thermal systems) and liquefied natural gas (LNG) storage facilities. For energy storage facilities with at least 1 megawatt capacity, payments are calculated as $2,000 per megawatt, split between the local city/town (two-thirds) and county (one-third) or town (one-third) and county (two-thirds). For LNG storage facilities, payments are based on the property's net book value at 6 mills for cities/villages or 3 mills for towns, with the county receiving the remaining share. The bill ensures payments continue even if some facility units cease operation, maintaining consistent support for local governments.
