USVA - Sacramento

  • Sacramento, CA
  • 558kW
  • SMUD

COMPLETED: February 2014
CLIENT: McClellan Air Force Base USVA Hospital

Project Summary

The USVA McClellan project focuses on increased energy savings through installation of a commercial solar rooftop and solar carport system. This system expands on the previously installed rooftop system by adding an acre of carport solar panels for a total of three acres of solar arrays, with a total expected output of 558 kW. The newly installed carport system is expected to generate approximately 832,000 kWh annually, while the rooftop system will generate 60,800 kWh. The solar carport system will also provide shade for vehicles and improved lighting at night. The entire solar generating facility will be interconnected and operate parallel to the Sacramento Municipal Utility District (SMUD).

Blue Oak Energy Scope

Engineering, procurement, and construction (EPC).
BOE teamed up with Solar Power Integrators, a turn-key development and project management company, to deploy this phase of the project.

Project Goals

The McClellan project builds on an existing onsite solar array with the goal of significantly reducing McClellan Hospital’s electricity usage. In installing an enhanced photovoltaic system, McClellan joins 30 other VA facilities in the shared goal of investing in renewable energy and increased sustainability, within the framework of the Strategic Sustainability Performance Plan. In addition to providing energy savings, the solar carport system is expected to serve as a shading and cooling area for parked vehicles during high temperatures.
