In an effort to become a part of California's clean energy grid and to save money powering city buildings and facilities, Siemens developed a solar program for Wasco under California's Renewable Energy Self-Generation Bill Credit Transfer (RES-BCT) program. Under RES-BCT, Wasco could export energy from the project to the grid and receive generation credits to benefit other city accounts.
The project involved building a solar array on a disused burn dump and includes 5,346 Silfab 345 watt panels and 27 ABB Trio 50 KW inverters power the 1.8 MW array. So as not to disturb the soil, HOLT Renewables mounted the panels on a GameChange ballasted racking system, surrounded by a ballasted protective fence. The arrays produced 3,134,680 kilowatt hours in year one of operation, about 60% of the city's energy needs.
