An Ameren Missouri program that offers rebates for energy efficiency could shut down by the end of the year after state regulators rejected a plan to extend it.
The Missouri Public Service Commission voted Thursday against extending the program for three more years, saying the utility needs a better method to measure electricity savings.
The St. Louis Post reports commissioners said they didn't want Ameren to collect more money than it needs to offset lower sales.
For the last three years, Ameren Missouri has offered several energy saving programs under a state law that reimburses the utility for reducing its customers' energy use. A separate charge on customers' bills funds the programs. Ameren uses the funds to cover lost sales and pay for rebates.
