U.S. Department of Veterans Affairs - Calverton, NY - Case Study


Courtesy of Boreal Renewable Energy Development

The U.S. Department of Veterans Affairs sought to build renewable energy at public facilities to reduce operating expenses and be more self-reliant. Boreal evaluated locations, recommended appropriate technologies to address energy demand, costs and aesthetic concerns. For Calverton National Cemetery on Long Island, the visitor center and public-area lighting is delivered by a 92-kW photovoltaic array.

Client Need:

Thousands of visitors and surviving family members every year pay respects to military veterans at national cemeteries. These facilities are expensive to operate with open space that includes parking, visitor center buildings, groundskeeping and security facilities. Federal real estate managers chose Boreal to evaluate the potential benefits and financial impact of renewable energy. Boreal was then chosen to provide the design of a photovoltaic (PV) system on the Calverton National Cemetery.

Solved: Wind/Solar Feasibility Arrow Design/Build Arrow Construction/Installation

For the Calverton cemetery, Boreal prepared custom designs of fixed-tilt and single-axis tracking PV solar systems, and compared the economics. Boreal eventually provided the final design of a 92 kW DC ground-mounted fixed-tilt PV system for construction. Working with partner Williams Construction Co., Boreal helped bring these two projects to completion, generating electricity.


The 92 kW PV system is generating over 110,000 kWh electricity annually. This was the largest ground-mount PV system in the VA system and advanced efforts by. Veterans Affairs towards energy efficiency goals consistent with Presidential Executive Order 13514 that sets out sustainability goals for all federal agencies.

Project notes

The federal government is the largest U.S. energy consumer, occupying nearly 500,000 buildings, operating more than 600,000 vehicles, employing more than 1.8 million civilians and purchasing more than $500 billion per year in goods and services.
