Project Description

Primary Energy's Naval Station CHP Facility is a 46.5 MW combined heat and power (CHP) plant which serves the U.S. Navy's San Diego Naval Station (Navsta) on the eastern edge of San Diego Bay. Steam produced by the CHP plant and 2 auxiliary boilers is supplied to the Navy and is used within ships berthed along 12 miles of piers and also for the substantial network of buildings across the 1,000 acre site. Electric output is sold to San Diego Gas & Electric Company (SDG&E) under a long-term power purchase agreement.

Benefits

The Naval Station CHP facility provides 100% of Navsta's annual steam requirements and has the ability to provide electricity directly to the Navy if required, adding reliability to this critical Navy facility. The CHP plant is equipped with selective catalytic reduction technology and a carbon monoxide (CO) catalyst which substantially reduces nitrogen oxide (NOx) and CO emissions. The production of both useful electricity and thermal energy from the CHP facility has the effect of reducing regional emissions by an average of over 400 tons of NOx, 800 tons of SO2, and 250,000 tons of CO2 per year. In addition, the Navy and SDG&E benefit from both lower energy costs and increased local reliability.
