Sempra US Gas & Power has finalised joint-venture (JV) agreements with Consolidated Edison Development for two of its plants: the 150MW Copper Mountain Solar II plant near Las Vegas and the 150MW Mesquite Solar I plant near Phoenix.

Announced in May 2013, the agreements will see each company holding 50% interest in each solar project, which are currently owned by Sempra.

Located in Arlington, Arizona, Mesquite Solar I, which generates enough clean electricity to power around 56,000 homes, has created around 300 local construction jobs and seven permanent operational jobs.

Mesquite Solar I, which has secured a $337m loan from the US Department of Energy in September 2011, started construction in middle of that year and became fully operational in December 2012.

"Copper Mountain Solar II generates enough renewable electricity to power 45,000 homes."

The project, which is part of the around 700MW Mesquite Solar complex, is supplying its output to Pacific Gas & Electric under a 20-year power purchase agreement. Once all the phases are complete, the Mesquite Solar complex will be North America's largest solar PV installation.

Located in Boulder City, Nevada, Copper Mountain Solar II generates enough renewable electricity to power 45,000 homes. The facility will also sell its output to Pacific Gas & Electric under a 20-year contract.

Sempra has started construction on the first stage of Copper Mountain Solar II in December 2011 and has brought into operation the first 92MW capacity so far and expects to add the remaining 58MW capacity by 2015.

The Copper Mountain solar complex is comprised of three phases with phase one called Copper Mountain Solar I, which became operational in 2010, comprising of 58MW capacity, while phase three or Copper Mountain Solar III will have a proposed generating capacity of 250MW.
