SPG Solar wraps up solar power system in California
Oct 23, 2012 - US solar system provider SPG Solar Inc today said it had completed a solar tracking power system at the Williams Wastewater Treatment Plant of the city of Williams in California.
SPG Solar has set up the solar system for no upfront costs by the city. Local utility PG&E is providing incentives for the system. The city will purchase the output of the facility under a power purchase agreement (PPA), arranged by SPG Solar, to supply its wastewater treatment plant.
The system, which uses SPG Solar's All Weather SunSeeker single-axis tracker, will produce 522,000 kWh of power, enough to supply some 50 households a year and will save USD 1.4 million (EUR 1.1m) in energy costs for the city over the next 20 years, SPG Solar estimates.
The Williams city solar system is SPG Solar's 10 MW of solar tracker projects scheduled to be completed in the second half of the current year, the company added.
