JACKSON (AP) — Entergy Mississippi says electricity rates should drop slightly beginning Saturday.

The company says bills for average residential customers — those using 1,000 kilowatt hours per month — will be $1.27 lower for the next three months.

Entergy says the state Public Service Commission had approved the lower quarterly fuel-rate adjustments. Entergy officials said a key factor in bills going down has been the reduction in cost of natural gas, a standard electricity source for the utility.

A typical customer’s bill will average about $88.40 per month from October through December.
