BRUSH is a proud supplier of DAX generators to the award winning Panoche Energy Center project near Fresno California. Awarded "Top Plant" by the POWER magazine for its innovative design and fast tracked construction schedule the 400-MW simple-cycle peaking power plant has an ability to be at full load within 10 minutes of start. The BRUSH generators are driven by a gas turbine which combines Aero derivative and industrial gas turbine technology with an intercooler to boost the overall output capability.
The Panoche Energy Center LLC is owned by Energy Investment Funds (EIF) and was constructed by Kiewit Power Engineers. Wood Group Power Services operate and maintain the operating power plant under overall facility management of Power Plant Management Services.
The generators selected for this project were BRUSH frame BDAX98-330ER for direct outdoor mounting on the customer’s foundation with top mounted inlet filters. This high inertia generator design assists the gas turbine in maintaining speed under fast load changes as well as ride through of external utility grid disturbances.
One key feature of the engine package is a fast start capability – to ramp from a cold start to full load in 9.5 minutes, a performance proven during first engine test program at the assembly and test facility in Houston Texas.
These large turbines and generators (major loads weighed up to 200 tons) posed exceptional challenges during generator delivery from the BRUSH Czech Republic manufacturing plant. The four turbines packages were delivered and set in place during the second ½ of 2008 with commissioning and full start up completed in June 1, 2009.
During just one month since start up all four 103MW units were started and stopped 83 times. The plant has had a start up reliability of 99.6%.
