Griffith Energy to Construct 2 Megawatt Behind-the-Meter Solar Project

The project will serve to offset Griffith's auxiliary electricity requirements, online or offline, and reduce its greenhouse gas emissions footprint by approximately 3.5 million pounds of carbon dioxide (CO2) per year, which is equivalent to removing 350 cars from the road. With a reduced need to self-supply auxiliary energy with natural gas and related cooling water, the project will also offset the power plant's water consumption.

The first phase of the project, which is approximately 80 percent complete, will consist of 700.3 kilowatts (KW) of rooftop-mounted solar panels. Construction on the second phase is expected to be completed by early 2024, and will incorporate approximately 1.3 MW of ground-mounted solar panels with single axis tracking. At its peak, the project will seek to employ 25 local construction personnel.

"This behind-the-meter solar project is highly economical, and we believe it represents the fastest way to get solar energy on the grid," said Joe Alves, managing director at ArcLight. "We see this as a template for other industrial and thermal generation facilities in the Desert Southwest. We are looking forward to working on larger investment projects in Mohave County and throughout Arizona."

In addition to the behind-the-meter solar project at Griffith, ArcLight, in partnership with its affiliates Griffith, Griffith Solar, LLC, and Elevate Renewables F7, LLC ("Elevate Renewables"), is currently developing a 25 MW solar plus 25 MW four-hour Battery Energy Storage System (BESS) with additional expansion opportunities in Mohave County.
