Missouri's largest utility, Ameren Missouri, is seeking an early halt to a solar rebate program that rewards consumers for using alternative energy sources.
Kansas City Power & Light made a similar request in July.
The St. Louis Post-Dispatch reports Ameren Missouri is asking the Missouri Public Service Commission for permission to curtail payment of millions of dollars in solar rebates before the year's end.
The company says it has received more than $35 million in solar rebate requests, creating a financial strain.
Missouri voters approved a 2008 ballot measure that requires investor-owned utilities to derive a certain percentage of their electric generation from renewable resources. The law caps rate increases derived from that measure at 1 percent.
