JEFFERSON CITY, Mo. (AP) — St. Louis-based electric utility Ameren Missouri says it's setting aside $5 million to help low-income customers with energy bills.

Ameren on Thursday announced about $1 million of that will go to groups including the United Way and Heat-Up Missouri to help those hit by high summer temperatures this year.

Another $4 million will be doled out through 2020.

The money will go to crisis energy assistance during extreme temperatures, weatherization help and equipment repair.

Ameren says the money is coming from corporate earnings.

Electric rates for Ameren customers also dropped 6 percent in August. That's the result of federal tax reductions passed by Congress in December and approved by Missouri lawmakers and regulators earlier this year.
