(Updates with company comment)

NEW YORK, July 1 (Reuters) - Exelon Corp (EXC.N) expected the 1,112-megawatt Unit 3 at the Peach Bottom nuclear power station in Pennsylvania to return to full power by Wednesday morning, a spokeswoman for the plant said.

Operators reduced the unit for maintenance on the main condenser.

The unit was operating at full power early Tuesday and 65 percent early Wednesday, according to a report from the U.S. Nuclear Regulatory Commission.

The 2,224 MW Peach Bottom station, which entered service in 1974, is located in Peach Bottom in York County about 75 miles southwest of Philadelphia. It has two 1,112 MW units, 2 and 3. The NRC renewed the plant's original 40-year operating licenses in 2003 for another 20 years until 2033 and 2034.

Unit 2 meanwhile continued to operate at full power.

One MW powers about 800 homes in Pennsylvania.

Exelon Nuclear, a unit of Exelon's Exelon Generation Co LLC subsidiary, operates the station for its owners: Exelon (50 percent) and Public Service Enterprise Group Inc (PEG.N) (50 percent).

Exelon, of Chicago, owns and operates more than 38,000 MW of generating capacity, markets energy commodities, and transmits and distributes electricity to about 5.4 million customers in northern Illinois and southeast Pennsylvania and natural gas to about 480,000 the Philadelphia area.

PSEG, of Newark, New Jersey, owns and operates more than 16,500 MW of generating capacity, markets energy commodities, and transmits and distributes electricity to 2.1 million customers and natural gas to 1.7 million customers in New Jersey and another 2.9 million customers around the world.
