New Californian municipal plant ready for peak demand

3 June 2005 – The largest municipal power plant to be approved by the California Energy Commission is due to begin commercial operation in time to help meet the US state’s peak energy needs.

Representatives from the six cities that funded the $234m facility, named Magnolia, gathered on Thursday for a dedication ceremony before the plant starts generating in mid-July. The 310 MW plant will be used to power the cities of Anaheim, Burbank, Cerritos, Colton, Glendale and Pasadena and will be available to meet the needs of the state if a power crisis arises this summer.

Ron Davis, past president of Southern California Public Power Authority and Magnolia’s project developer, said: “Today, we are dedicating an important and strategic power plant that will deliver reliable, clean and competitive generation that will serve more than 250 000 Southern California residents.”

The project has 90 per cent cleaner emissions than the plant it replaced, which had served since 1941.

Magnolia includes a combustion turbine engine, heat recovery steam generator and stack, steam turbine generator, cooling towers and a zero liquid discharge system. The generation facilities have supplemental firing in the heat recovery steam generator and steam injection in the combustion turbine to increase power output from a normal level of 242 MW up to 310 MW. As a base load plant, it will be in operation for approximately 8000 hours per year.
