Ameren Missouri has received approval from a state regulatory commission to build solar generation facilities in O'Fallon, according to a press release.
The Missouri Public Service Commission has approved an agreement that grants a certificate of convenience and necessity to Ameren to build the facilities.
The planned facility will be the largest in Missouri, producing an average of about 7,700 megawatt-hours of solar-generated energy per year. Ameren plans to start construction in May and complete it by the end of the year.
According to the application, the facility will be adjacent to an existing Ameren Missouri substation.
The agreement approved by the Commission was submitted by Ameren Missouri, Earth Island Institute d/b/a Renew Missouri, the Public Service Commission Staff and the Missouri Division of Energy.
Ameren Missouri must obtain a land disturbance permit from the Missouri Department of Natural Resources and file a copy of that permit with the Public Service Commission.
