St. Louis aldermen clash over data center zoning. Bill sponsors say amendments ‘weaken’ rules

St. Louis aldermen clashed over amendments to proposed data center zoning rules, which some sponsors believe weaken the original intent, particularly regarding renewable energy requirements. The approved amendments to Board Bill 49 mean it will return to the city's Planning Commission before a final vote. Alderwomen Anne Schweitzer and Alisha Sonnier expressed concern that the changes prioritize economic growth over well-being and environmental goals.

Ameren Missouri requests mid-2027 rate increase, would raise average Missourian’s bill by $13

Ameren Missouri has requested a mid-2027 rate increase of $343 million, which would raise the average customer's electricity bill by $13, citing investments in infrastructure and growing demand from "large-load customers" like data centers. Consumer protection groups are scrutinizing the proposal, arguing that data centers should bear more of the costs for new generation needed to meet their significant energy demands. The Missouri Public Service Commission will review the request over the next 11 months.

ComEd rates are going up again this summer, and rising demand is largely to blame

ComEd rates in Illinois are set to increase this summer, largely driven by rising demand for electricity, particularly from data centers supporting the artificial intelligence industry. The rate hike also stems from increased prices set by power-generating companies at a recent PJM Interconnection auction and the discontinuation of a temporary customer credit.
