Modifies provisions for renewable energy resources

HB 1687 establishes a renewable energy portfolio standard requiring electric utilities in Missouri to generate or purchase a growing percentage of their electricity from renewable sources like wind, solar, and hydropower. The bill sets specific targets, mandating that renewable energy make up at least 15% of sales by 2024 and reaching 100% by 2059, with a minimum of 2% coming specifically from solar power. Utilities can meet these goals by generating their own power or buying renewable energy credits, and the law includes a declining solar rebate program for customers who install new solar systems on their properties. To ensure compliance, the bill authorizes the Public Service Commission to track progress, impose penalties on utilities that miss targets, and recover the costs of meeting these requirements through utility rates.
