Ironwood, Chuckawalla State Prisons Host 8.6 MWs of DuraTrack HZ™ Tracking Systems

Array Technologies’ expansions bring Blythe, CA. total to 11 MWs

Albuquerque, NM – 4/9/12 – Array Technologies has announced the completion of two 4.3 MW expansions of solar trackers located just outside the Ironwood and Chuckawalla Valley State Prisons near Blythe, CA.

1 MW of DuraTrack HZ™ trackers completed in late May 2008 was expanded by 4.3 MW at Ironwood State Prison after generating reliable solar energy for several years for the state of California. Over the next 20 years, the expanded system will offset emissions equal to removing 3,770 cars from the road annually.

Chuckawalla State Prison also decided to expand their current 1 MW of fixed-tilt solar installed in 2006 with 4.3 MW of Array Technologies’ DuraTrack HZ™ system, as the trackers generate up to 25% more energy than conventional fixed-rack applications. This ensures the taxpayers of California receive the maximum return on their investment for the project.

The Chuckawalla site will offset CO2 emissions equivalent to taking 3,100 cars off the road annually for the project’s lifetime.

Both owned and operated by EPC SunEdison, the California Department of Corrections and Rehabilitation will utilize the energy produced by both facilities under a power-purchasing agreement.

The expansions help the state of California meet former Governor Schwarzenegger’s Executive Order S-20-04, which directs state agencies to take measures to reduce state-owned buildings’ conventional energy costs by 20% by 2015.
