Wartsila supplies gas engines to California power plant

Modesto, Calif., August 18, 2011 — The newly commissioned power plant located in Modesto, California, provides the community with the needed flexible, fast-start peaking generation to balance the expected increase in intermittent renewable generation resources.

Modesto Irrigation District built the peaking plant to support their goal of meeting California’s mandated 33 percent renewable energy in their generation portfolio by 2020.

The Woodland 3 Generation Project gas power plant was commissioned and handed over for commercial operation to MID, the electric utility serving the communities Modesto, Salida, Empire, Waterford, Mountain House and parts of Escalon, Oakdale, Ripon and Riverbank in July, 2011.

The 49.6 MW power plant has six generating sets, based on 20-cylinder Wartsila 34SG engines running on natural gas, which meet the stringent California state permit requirements. Wartsila was selected for this project because of the plant’s efficiency at part load, its fast-start flexibility and the low environmental impact.

The ability to quickly dispatch any or all of the six Wartsila units anywhere from 4 to 49 MW, allows the district’s remaining generating portfolio to be operated in a more efficient manner.

Wartsila’s power plant features include the ability to reach full plant output in just five minutes, and to provide 25 percent power in two minutes. It offers constant performance and rapid response, regardless of the state of the grid and the ambient conditions.
