Unit 2 at Diablo Canyon Power Plant safely shut down

April 26, 2012

AVILA BEACH, Calif. — Pacific Gas and Electric Company (PG&E) today announced that operators safely shut down Unit 2 at Diablo Canyon Power Plant due to an influx of sea salp — a small, jellyfish-like organism – in the intake structure.

PG&E will not restart Unit 2, which was operating at 24 percent power, until conditions improve at the intake structure. As previously announced, Unit 1 was safely shut down earlier this week for a planned refueling and maintenance outage.

Diablo Canyon Power Plant is a nuclear power facility owned and operated by PG&E. Its two units together produce approximately 2,300 net megawatts of greenhouse-gas-free electricity, about 10 percent of all electricity generated in California, and enough energy to meet the needs of more than three million Northern and Central Californians.

Pacific Gas and Electric Company, a subsidiary of PG&E Corporation (NYSE:PCG), is one of the largest combined natural gas and electric utilities in the United States. Based in San Francisco, with 20,000 employees, the company delivers some of the nation’s cleanest energy to 15 million people in northern and central California.
