Chevron Energy Solutions Completes United States Postal Service's Largest Solar Power and Efficiency Project
Rooftop array at the largest mail center in Northern California spans area of nearly two football fields, helps postal service cut energy purchases by more than one-third
OAKLAND, Calif., Nov. 1, 2006 -- Chevron Energy Solutions, a subsidiary of Chevron (NYSE: CVX), has completed the largest solar power and energy-efficiency project for the United States Postal Service (USPS) at its mail center in Northern California. The project at the Oakland Processing and Distribution Center reduces the facility's power purchases by more than one-third and is the latest indication that businesses and institutions are installing energy-efficiency measures to reduce costs and help fund on-site renewable power systems.
The Oakland project is one of dozens that Chevron Energy Solutions is developing at mail facilities throughout California, Arizona, Nevada and Hawaii under a multi year contract with the Postal Service. In Northern California alone, these high-efficiency and alternative power improvements will save the Postal Service more than $2 million per year in energy costs.
"The cost savings from these energy-efficient improvements are great enough to fund not only the equipment installations, but also renewable power systems," said Jim Davis, president of Chevron Energy Solutions. "We commend the U.S. Postal Service for implementing viable, market-driven projects that are helping to meet the rising global demand for energy in ways that benefit the environment."
The 910-kilowatt solar power system - the largest installed to date at a federal building - spans a rooftop area nearly the size of two football fields, and it will help meet electric demand during peak periods. Other energy-efficient upgrades on-site include high-quality lighting systems that improve work areas for Postal Service employees; motion-sensor technologies that automatically control where light is used; three 300-ton centrifugal chillers - which eliminate ozone-depleting chlorofluorocarbon (CFC) refrigerants from the facility - and other heating, ventilation and air conditioning systems; a new energy management system to control HVAC equipment; high-efficiency air compressors; and water conservation measures.
The improvements at the facility, the largest of its kind in Northern California, will lower total annual electricity purchases by almost 11 million kilowatt hours. This reduced demand for power translates to 7,400 fewer tons of carbon dioxide emitted by the local electric utility annually -- the same volume of carbon dioxide that would be absorbed by planting more than 2,000 acres of trees.
The Oakland project was installed as part of a contract with Chevron Energy Solutions that included energy-efficiency improvements at Postal Service facilities in Berkeley, San Leandro and Livermore. The $18 million total cost of all these installations is funded primarily by $10.1 million in energy savings, $4.5 million from the USPS's CFC refrigerant replacement program, and $3.4 million from Pacific Gas and Electric Company, which administers the state's incentive programs for self-generation and efficiency improvements in Northern and Central California.
Chevron Energy Solutions partners with institutions and businesses to improve facilities, increase efficiency, reduce energy consumption and costs, and ensure reliable, high-quality energy for critical operations. Chevron employs proven technologies to meet customers' specific needs, including infrastructure technologies, energy controls, solar photovoltaics, fuel cells, biomass and other systems.
