Electric Rates

Data centers and other large consumers of electricity will pay special rates under Ameren Missouri’s new tariff approved Monday.

The Missouri Public Service Commission approved a large-load rate submitted by Evergy, which operates in Kansas and Missouri, and that was supported by most parties in the case.

The utility disconnected more than 17,000 households that were behind on their bills in October, according to its latest public filings.

Municipally owned electric utilities are rare in the St. Louis area. Kirkwood owns its own utility and recently announced a rate increase.

Ameren Missouri is courting AI data centers by building new power plants and offering them lower bulk electric rates, but their unprecedented energy demands could drive up everyone’s electricity bills.

Missouri’s utility regulator’s staff says the Public Service Commission should reject a new proposal from Ameren.

Missouri regulators approved an increase for Ameren’s electric rates. Bills will go up by about 12% starting in June.

The bill will bring big changes to how utilities operate and bill customers in Missouri.

Ameren Missouri announced plans to upgrade its grid and build new power plants to meet an anticipated increase in demand from companies moving to the state.

The 15% rate hike would bring in about $446 million for Ameren Missouri if it's approved by state regulators.
