SCS/SB 757 - Under the act, prior to the closure of an existing electric generating power plant if the closure occurs on or after January 1, 2025, an electrical corporation, registered and doing business in Missouri, shall first certify to the Public Service Commission that it has secured and placed on the electric grid an equal or greater amount of replacement reliable electric generation as accredited power resources as defined by the regional transmission operator. To determine if an equal or greater amount of reliable electric generation is being placed on the electric grid, the electrical corporation shall compare the relevant regional transmission operator's average of the summer and winter accredited capacity for the generation technology of the closing electric plant to the relevant regional transmission operator's average of the summer and winter accredited capacity of the replacement reliable electric generation. Such average accredited capacity shall equal or exceed average accredited capacity for the existing electric generating plant. Adequate electric transmission lines shall be in place and the replacement reliable electric generation shall be fully operational concurrently with the closure of the existing electric generating plant, except where some or all of the replacement reliable electric generation utilized interconnection facilities used by the existing electric generating power plant as described in the act. If replacement reliable electric generation utilized interconnection facilities utilized by the existing electric power plant, the replacement facilities shall be fully operational without 120 days of the closure of the existing electric plant. If an existing electric power plant is closed as a result of an unexpected or unplanned cause or event, as defined in the act, the electrical corporation shall install replacement reliable electric generation as soon as is practical. During any periods where the replacement reliable electric generation is not fully operational by the time of the closure of an existing power plant, the electrical corporation shall acquire additional available generation capacity through a firm purchase power contract as described in the act. The average of the summer and winter accredited capacity of the replacement reliable electric generation under the act shall be equal to or greater than the average accredited capacity of the existing electric generation power plant recorded by the regional transmission operator as of the time construction begins on the replacement reliable electric generation. The Public Service Commission shall promulgate rules that the requirements under the act shall be met by the replacement reliable electric generation. Reliable electric generation may be constructed outside the state if it is connected to the electric grid of the regional transmission operator of which the electrical corporation is a member. On or before the date that the new reliable electric generation is placed in service, the electrical corporation shall provide certification to the public service commission, the general assembly, and the governor that it has met the requirements of the act. The act is similar to provisions in SCS/HCS/HB 1746 (2024), HCS/HB 1753 (2024), SB 709 (2023) and SB 717 (2023). JULIA SHEVELEVA
