Data Centers
Data centers are specialized facilities that house the computing and networking systems needed to run applications and to store, process, and manage large amounts of data.
The demand to develop new data centers has been rapidly increasing amidst the Artificial Intelligence (AI) boom. As data centers become increasingly common nationwide and in the St. Louis region, concerns have arisen around their environmental, economic, and community impacts.
Large-scale data centers can require tremendous amounts of water and energy to sustain, straining local utilities and potentially impacting residents’ utility bills; create noise and heat pollution; and cause other nuisances that negatively affect surrounding neighborhoods.
Phases
Missouri Public Service Commission approves Consumer Protection Plan
On November 24, 2025, the Missouri Public Service Commission approved a consumer protection plan that governs how "large-load customers" such as data centers pay for electricity from Ameren. The amended plan includes provisions advocated for by the Sierra Club and Renew Missouri to protect consumers. These rules apply to any Ameren customer that uses more than 75 MW of energy per month.
These regulations will inform the City of St. Louis' ongoing discussions on zoning, water rate, and community benefit requirements for companies that seek to site data centers within St. Louis.
