Under the PPA, Pacific Gas and Electric Company (PG&E) will purchase the energy generated from the project, 92 MW of which is scheduled to be installed by the end of 2012. Meanwhile, the remaining 58 MW is expected to be completed by 2015. In a statement, Sempra added, "Under the terms of the contract, PG&E has the option to accelerate the commercial operation date of the second phase."
Construction on the first phase of the photovoltaic project, located in Boulder City, Nevada, will get underway this year. When complete, it will occupy an area of 1,100 acres and should generate enough energy to supply 45,000 homes.
First Solar will supply the thin film photovoltaic panels needed for the project, in addition to acting as engineering, procurement and construction contractor.
Sempra has already installed 58 MW of photovoltaics in Boulder City, and has a further 150 MW under construction in Arizona. By 2013, the company expects to have around 300 MW in operation.
