NEW YORK, June 25 (Reuters) - AES Corp's (AES.N) 485-megawatt Unit 5 at the Alamitos natural gas-fired power station in California returned to service by Wednesday afternoon, the California Independent System Operator said in a report.

The unit shut by Tuesday afternoon for unplanned reasons.

The 1,997 MW Alamitos plant is located in Long Beach in Los Angeles County about 25 miles south of Los Angeles. There are six units at Alamitos, including two 175 MW Units 1 and 2, the 332 MW Unit 3, the 335 MW Unit 4, the 485 MW Unit 5 and the 495 MW Unit 6.

Unit 1 entered service in 1956, Unit 2 in 1957, Unit 3 in 1961, Unit 4 in 1962, Unit 5 in 1964 and Unit 6 in 1966.

All of the other units were available for service.
