Missouri has one of the strictest laws in the nation, Missouri Senate Bill 4, requiring data centers to pay for the costs to serve them while providing robust protection for all other customers. Ameren Missouri’s Powering Missouri Growth Plan, in alignment with Missouri Senate Bill 4, requires new large load businesses to pay upfront 100% of direct interconnection costs and upfront financial security and collateral requirements equivalent to two years of minimum monthly bills, and Ameren Missouri will ask state regulators to ensure that the rates paid by nearby data centers fully cover the costs of the entire project in a future regulatory filing.
