The new contract follows the $2.4m contract that Pepco Energy began implementing last year.
The expansion of the project will allow Pepco Energy to help the county’s public schools further reduce energy consumption and costs by implementing energy conservation measures in two additional school facilities.
Under the contract, the company will retrofit and replace lighting and water fixtures, as well as install more energy-efficient boilers, variable frequency drives and domestic hot water systems.
Construction began in January and is scheduled to be complete in October this year.
The total project will increase the energy savings to approximately $3.6m over the ten-year term, as well as reduce energy and water use by approximately 24% and 30%, respectively.
The first phase of the project reduced carbon dioxide emissions by the Prince William County Schools by approximately 1,200 metric tons annually, and the second phase is expected to increase the reductions of emissions for the school system to nearly 3,200 metric tons per year.
Pepco Energy Services is a subsidiary of Pepco Holdings, and provides commercial, institutional, government and industrial customers with competitive energy efficiency services, including renewable energy and combined heat and power.
