LONDONDERRY TWP, PA- Three Mile Island Unit 1 returned to service yesterday at 10:50 p.m. when operators connected the plant’s turbine generator to the regional power grid.   The turbine generator shut down on September 19 due to a faulty electrical card on a plant system.  Plant personnel replaced the faulty electrical card.

Three Mile Island Unit 1 generates 852 megawatts of carbon free power - enough electricity for about 800,000 homes.  Electric customers were not affected by the plant being off line.
