Dynegy shuts Calif. Moss Landing 6 natgas unit

HOUSTON, May 21 (Reuters) - Dynegy Inc's (DYN.N) 754-megawatt Unit 6 at the Moss Landing natural-gas-fired power station in California shut by Thursday afternoon for unplanned reasons, the California ISO said in a report.

Moss Landing 2, rated at 510-MW, shut earlier in the week.

The 2,498 MW Moss Landing station is located near Salinas in Monterey County about 90 miles (145 km) south of San Francisco.

There are several units at the station, including the two 510 MW combined-cycle units 1 and 2 (which entered service in 2002), and two 739 MW units, 6 (1967) and 7 (1968). Each of the 510 MW combined cycle units is made up of two 165 MW gas turbines and one 180 MW steam turbine.

Other units were available for service.

One MW powers about 700 homes in California.

Dynegy, of Houston, owns and operates more than 18,000 MW of generating capacity and markets energy commodities in the United States. (Reporting by Eileen O'Grady; Editing by Christian Wiessner)
