North Kern State, Tehachapi Prisons Set to Generate 10 MWs with DuraTrack HZ™ Trackers

Department of Corrections solar projects part of 23 MW expansion

Albuquerque, NM – 10/10/11 – Array Technologies has announced the final shipment of two DuraTrack HZ™ tracking systems for California’s North Kern State and Tehachapi Prisons, bringing to total solar capacity of the California Department of Corrections to 23 MWs.

Owned and operated by EPC SunEdison, the power generated onsite will be sold to the California Department of Corrections at a levelized cost for the lifetime of the projects. By locking in a low rate of electricity, the state is expecting to save $55 million over 20 years once the expansion is complete—a move that protects taxpayer dollars while helping to mitigate the prison’s impact on the environment.

The DuraTrack HZ™ system generates up to 25% more energy than typical fixed-rack installations while maximizing land coverage, resulting in a system that provides the greatest return on investment in the industry. The DuraTrack HZ™ system will provide the greatest savings to the state of California—while delivering robust performance day-in and day-out.

In April, California Governor Brown signed a law requiring one-third of the state’s electricity to come from renewables by 2020, and the trackers from Array Technologies will help the California Department of Corrections meet this goal.
