Mesquite Solar project

Solar power plant in Maricopa County, Arizona From Wikipedia, the free encyclopedia

The Mesquite Solar project is a 512.5-megawatt (MWAC) photovoltaic power plant in Arlington, Maricopa County, Arizona, owned by Sempra Generation and Consolidated Edison Development Inc. The first three phases of the project were constructed using more than 2.1 million crystalline silicon solar panels made by Suntech Power.[1][2] Mesquite 4 and 5 added another 112.5 MW and 70 MW of battery storage.

Project details

Construction of Phase 1 over a 3.6 km2 site adjacent the Palo Verde Nuclear Generating Station began in 2011 and was completed in January 2013.[3][4] It has a nameplate capacity of 150 megawatts (MW) that is contracted through a 20-year Power Purchase Agreement (PPA) with Pacific Gas and Electric Company (PG&E).[5] The EPC contractor was Zachry Holdings.[6] Phase 1 cost about $600 million, is projected to generate more than 350 gigawatt-hours of electricity annually (an average of about 40 MW), and will offset roughly 200,000 tons of carbon emissions each year.[6][7]

Mesquite Solar One (August 2012)

Phase 2 (100MW) and Phase 3 (150MW) were both completed in December 2016.[8][9][10] The panels are mounted on single-axis trackers to increase electricity production.

Mesquite 4 is a 52.5 MW solar farm with 10 MW of batteries. Mesquite 5 is a 60 MW solar farm with 60 MW of batteries. Mesquite 4 came online in January 2024 while Mesquite 5 came online in July 2023. [11]
