Ameren seeks to build 400 megawatts of additional solar generation

Ameren Missouri is seeking Public Service Commission approval to add 400 MW of solar generation and 545 MW of energy storage across several Missouri counties. This expansion is partly driven by the anticipated electricity demands of new data centers from companies like Google and Amazon in the state. The Missouri Office of Public Counsel has expressed concerns that the solar facilities primarily benefit large-load customers.

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.

BIG READ | Power-hungry US data centres imperil residents and environment$

The Trump administration reversed federal soot standards, previously set to improve air quality in cities like St. Louis, to prioritize electricity demand from data centers and the AI boom. This decision ensures coal plants, like Ameren's Labadie Energy Center, can continue operating without costly upgrades, leading to renewed concerns from environmental activists about increased pollution and health risks. Data center growth is projected to create significant new electricity demand, which utilities like Ameren are preparing to meet, including for large projects like an Amazon Web Services facility in Montgomery County.
