Sempra, Con Edison form solar power joint venture

Sempra U.S. Gas & Power and Consolidated Edison Development (Con Edison) became equal partners in two of Sempra U.S. Gas & Power’s solar power facilities, the 150 MW Copper Mountain Solar 2 plant near Las Vegas and the 150 MW Mesquite Solar 1 plant near Phoenix.

Under the terms of the joint-venture agreements, which were announced in May 2013, each company will own a 50 percent interest in each of the solar facilities. The terms of the transaction were not disclosed.

Mesquite Solar 1, the first phase of Sempra U.S. Gas & Power’s Mesquite Solar complex located in Arlington, Ariz., was completed in late 2012. Mesquite Solar 1 generates enough clean electricity for about 56,000 homes. Power from the facility has been fully sold to Pacific Gas & Electric (PG&E) under a 20-year contract.

The first phase of Copper Mountain Solar 2 is complete and is currently generating 92-MW of solar power. When the second phase is fully constructed — expected in 2015 — the project’s total operating capacity will be 150-MW. The solar power plant generates enough clean energy to power about 45,000 homes. Power from the facility has been fully sold to PG&E under a 25-year contract.
