Regulators give Ameren Missouri OK to build gas plant and batteries, in part for data centers

Posted online

Regulators gave Ameren Missouri permission to build a new natural gas and battery storage energy center in Jefferson County on Wednesday.

The Missouri Public Service Commission approved the Big Hollow Energy Center, which will be a simple-cycle natural gas plant — a type that can be turned on quickly to meet demand when a lot of people are using electricity — and a battery energy storage system.

The natural gas plant will be able to generate 800 megawatts of power, which is about two-thirds the capacity of Ameren’s Callaway nuclear power plant, while the battery storage system will be able to deliver 400MW of power for four hours.
