Missouri utility regulators have approved a $260 million rate increase for electric customers of Ameren Missouri.
The rate increase approved Wednesday could mean an extra $10 a month on an average residential bill when it takes effect in January.
It's intended to cover such things as the utility's rising fuel costs, infrastructure improvements, vegetation trimming and storm repairs.
About $90 million of the rate increase will go toward energy efficiency programs that could ultimately save money for residents and businesses.
Missouri utility regulators are warning people of a scam claiming that President Barack Obama is providing credits on utility bills through a new federal program.
The Missouri Public Service Commission says the scam, which gained national attention last week, has also targeted some residents in Missouri.
