Bill Summary
This bill provides utility aid payments to counties and municipalities where energy storage facilities are located. Under the bill, the Department of Administration distributes to each city and village in which an energy storage facility is located two-thirds of the amount calculated by multiplying the facility[s megawatt capacity by $2,000, and DOA distributes to the county in which such a facility is located one-third of the amount calculated by multiplying the facility[s megawatt capacity by $2,000. DOA distributes to each town in which an energy storage facility is located one-third of the amount calculated by multiplying the facility[s megawatt capacity by $2,000, and DOA distributes to the county in which such a facility is located two-thirds of the amount calculated by multiplying the facility[s megawatt capacity by $2,000. The bill defines an Xenergy storage facilityY as property owned by a light, heat, and power company, electric cooperative, or municipal electric company that receives electrical energy, stores the energy in a different form, and converts that other form of energy back to electrical energy for sale or to use to provide reliability or economic benefits to the electric grid. Under the bill, Xenergy storage facilityY includes hydroelectric pumped storage, compressed air energy storage, regenerative fuel cells, batteries, and similar technologies. The bill also provides utility aid payments to counties and municipalities where liquefied natural gas storage facilities (LNG storage facilities) are located. The payment received by a city or village where an LNG storage facility is located is determined by multiplying the net book value of the LNG storage facility by six mills and by three mills in the case of a town. The payment received by a county where an LNG storage facility is located is determined by multiplying the net book value of the LNG storage facility by three mills if the facility is located in a city or village and by six mills if the facility is located in a town. For further information see the state and local fiscal estimate, which will be printed as an appendix to this bill.
AI Summary
This bill establishes provisions for utility aid payments to municipalities and counties hosting energy storage and liquefied natural gas storage facilities. The bill defines an "energy storage facility" as a property interconnected to the electrical grid that can receive, store, and convert electrical energy back into usable electricity, including technologies like hydroelectric pumped storage, compressed air storage, batteries, and hydrogen storage. A "liquefied natural gas storage facility" is defined as a storage facility owned by specific types of power companies. The legislation creates a payment system where municipalities and counties receive financial compensation based on the facility's characteristics: for energy storage facilities, payments are calculated by multiplying the facility's name-plate capacity by $2,000, with different allocation percentages for cities, villages, towns, and counties; for liquefied natural gas storage facilities, payments are calculated using a mills-based approach on the facility's net book value. The bill specifies that these payments will first apply to distributions made after January 1, 2027, and ensures that if a facility has multiple storage or generation units, the payments will not be reduced if only some units cease operations. This legislation aims to provide financial support to local governments hosting critical energy infrastructure.
