Ameren Missouri, a subsidiary of Ameren Corp., has filed plans with the Missouri Public Service Commission to build three solar-plus-storage facilities across the state.
According to the utility, the projects would improve customer reliability and enable access to solar energy around the clock.
“These non-traditional solutions are expected to benefit customers by increasing reliability, growing the amount of renewable energy generation on the grid and investing in the communities we call home,” notes Michael Moehn, chairman and president of Ameren Missouri.
Ameren Missouri is investing approximately $68 million in these projects as part of the company’s Smart Energy Plan, which includes initiatives designed to create a smarter, stronger and more reliable energy grid and introduce new sources of renewable energy, all while keeping rates stable and predictable.
The new solar-plus-storage projects, expected to be completed next year, would be located in the communities of Green City, Richwoods and Utica.
Each location is expected to have a 10 MW solar facility, making them the three largest investor-owned utility solar installations in the state, the company claims. During sunny days, customers near the proposed facilities will receive their energy primarily from the solar facility. The solar energy will also charge the battery. In the case of a service interruption, each battery will be able to power connected homes for several hours, giving Ameren Missouri repair crews time to fix the service issue without causing an extended outage. Customers will also remain connected to the larger energy grid.
“This solution wasn’t available to us just two years ago,” says Kevin Anders, vice president of distribution operations and technical services. “Solar and storage technology has made significant strides in the past several years. Prices continue to decline, making them an attractive, affordable option for the communities we serve.”
The new facilities are part of the company’s plan to add 100 MW of solar generation by 2027. Ameren Missouri’s first community solar installation, located near St. Louis Lambert International Airport, recently began serving customers.
“Incorporating several types of renewable energy, and now energy storage, will help us achieve our goal of reducing carbon emissions 80 percent from 2005 levels by 2050,” Moehn adds.
