Ameren 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.

The electric utility is asking Missouri regulators to approve a 15% increase in rates, or about $17 more a month on average. Customers can share feedback on the raise at upcoming public hearings.

Together, the three new solar facilities can produce 500 megawatts of renewable energy. They are the energy companies largest solar effort to date.

The utility company was found in violation of the Clean Air Act for failing to install pollution controls when it updated the Rush Island Energy Center.

The Environmental Protection Agency estimates Rush Island released 275,000 tons of sulfur dioxide after it was updated without required pollution controls in 2007 and 2010.

Ameren Missouri has announced plans to expand its Community Solar program with a third solar facility to meet growing demand for renewable energy.

A federal program is sending millions of dollars to a handful of St. Louis-area school districts so they can replace diesel buses with all-electric models.

The plant would be located on the site of a former coal plant in south St. Louis County. Proponents of renewable energy say more transparency is needed as the utility plans an $800 million investment in a fossil fuel energy source.

The company was given a choice by a federal court to either shut down the Rush Island Energy Center or add expensive pollution controls.
