A wildfire that got its name from a geothermal generation complex came within scorching distance of The Geysers power plants themselves. The fire itself didn?t cause plant shutdowns, but it served to cut off the transmission lines leading out of the area, causing Calpine to curtail about 500 MW at the site. ?It got to within a few feet of the fence line,? said Calpine spokesperson Kent Robertson. The 12,500-acre Geysers fire started September 3 and was mostly tamped out by September 7. Transmission line owner Pacific Gas & Electric shut down the three 230 kV lines leading to Petaluma and Santa Rosa on the south side of the 1,000 MW Geysers facility, according to Robertson. Calpine owns units amounting to 750 MW of capacity in the 30-square-mile facility; the rest is owned by the Northern California Power Agency. By 6 p.m. Tuesday, all the Calpine plants were back on line. Calpine rerouted steam to one-third of its units on the north side of the rugged canyons, sending about 250 MW through a transmission line into Mendocino County, said Robertson.
