U.S. Navy to Deploy PowerLight PV System

The U.S. Navy will deploy a 750 kW photovoltaic system designed, manufactured and installed by PowerLight Corporation, which is the largest federal solar electric system in the country.

San Diego, California – November 12, 2002 [] This system makes use of existing parking spaces creating a solar electric carport at the Coronado Naval Base in San Diego, California. The installation is comprised of two contiguous solar arrays, covering a half-mile long parking structure that serves U.S. Navy personnel. In addition to providing shade for parked cars, the system generates the equivalent energy during the day to power over 935 homes. The PV system will reduce the demand on California’s power grid, as well as improve air quality by avoiding thousands of tons of polluting nitrogen oxide, sulfur dioxide and carbon dioxide emissions. “The deployment of solar power at Navy Region Southwest demonstrates the Navy’s commitment to using energy management practices that reduce energy consumption and control costs,” said Commander Pat Rios, NBC Public Works Officer. “Using clean generation is very consistent with our base’s mission of leveraging superior operational expertise and technologies.” “Solar power proved to be the ideal energy solution for Naval Base Coronado,” said Lieutenant Commander Wade Wilhelm, Navy Region Southwest Utilities Program Manager. “The photovoltaic system combines the environmental benefits of solar with the ability to provide on-site power that serves to reduce our vulnerability to disruptions of the power grid.” The 750 kW solar electric system was implemented as part of an Energy Savings Performance Contract (ESPC) project developed by NORESCO of Westborough, Mssachusetts. The photovoltaic system was designed, manufactured and installed by PowerLight Corporation of Berkeley, California. This photovoltaic system will produce approximately 1,244,000 kWh per year and is expected to save over US$228,000 in annual operating costs by avoiding purchases of expensive peak electricity. This energy project was made possible through the Department of Energy’s Western Region Super ESPC, developed and executed by the Navy’s ESPC team comprised of the Naval Facilities Engineering Service Center and the Naval Facilities Engineering Command Contracts Office. “We commend the Navy for taking such a strong leadership role in implementing clean, renewable solar power,” said PowerLight President Dan Shugar. “Wider deployment of onsite solar generation is helping to secure our nation’s energy independence and national security.” This system is the latest renewable or distributed generation system deployed by Navy Region Southwest. Other installations include three solar electric systems totaling 130 kW, wind generating capacity of 675 kW on San Clemente Island, 120 kW of micro-turbine technology at Naval Base Coronado as well as several fuel cell demonstration programs.
