The Copper Mountain Solar Facility is a 458 MWp〔(Copper Mountain Solar I )〕 solar photovoltaic power plant in Boulder City, Nevada.〔 Sempra Generation announced on December 1, 2010 that it had finished phase 1 of the project and the facility was generating electricity. When the facility entered service, it was the largest photovoltaic plant in the U.S. at 58 MW. The expected output of 100 GW·h/year from Copper Mountain Solar Facility phase 1 has been sold to Pacific Gas & Electric under a 20-year power purchase agreement (PPA).〔 Power generated from phase 2 has been sold to Pacific Gas & Electric under a 25-year power purchase agreement (PPA).〔http://www.semprausgp.com/energy-solutions/solar-cms2.html〕 Power generated from phase 3 is sold to the Southern California Public Power Authority. == History== Sempra Generation built the plant from January 2010 to December 1, 2010,〔 at a cost of about $141 million., although it appears this is just for 48 MW expansion. At its construction peak more than 350 workers were installing the 775,000 First Solar panels on the site.〔(America's Largest PV Power Plant Is Now Live ) (December 6, 2010), ''Renewable Energy World''.〕〔 An expansion of the facility by more than 200 MW was approved in 2010.〔 On August 4, 2011, Sempra announced a plan to expand the facility by 92 MW to be online in January 2013 and another 58 MW to be added by 2015.〔(Sempra to expand Copper Mountain solar plant ), Reuters, Aug 4, 201〕 Copper Mountain Solar 3 is the third phase of the Copper Mountain Solar complex. Construction on the 250 MW solar project began in 2013 and was completed in early 2015, with a formal dedication ceremony on 30th April 2015.〔http://sempra.mediaroom.com/index.php?s=19080&item=137041〕 This stage is capable of generating enough electricity to power about 80,000 homes.〔http://www.semprausgp.com/energy-solutions/solar-cms3.html〕 Copper Mountain Solar 4 is the fourth phase of the Copper Mountain Solar complex. Construction on the 94 MW expansion project is scheduled to commence in 2015, creating about 350 construction jobs at peak, with completion expected by year-end 2016.〔http://www.semprausgp.com/energy-solutions/solar-cms4.html〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Copper Mountain Solar Facility」の詳細全文を読む スポンサード リンク
