JACKSON, Miss. (AP) — Entergy Corp. will raise customer bills again starting in February to pay the costs of Entergy Mississippi buying a share of the Grand Gulf nuclear plant from sister company Entergy Arkansas.

A residential customer who uses 1,000 kilowatt hours per month will see his or her bill increase $2.78 per month from the current amount, according to the Mississippi Public Service Commission. The commission voted 3-0 Tuesday to approve the increase.
