The Board of Water Supply (BWS) has entered into a 20‐year, $33 million Energy Savings Performance Contract (ESPC) with NORESCO LLC. This partnership allows the BWS to implement comprehensive energy efficiency, renewable energy, and operational improvements which guarantees enough energy savings over the next 20 years to pay for the contract. The project is being financed by a loan from the Drinking Water State Revolving Fund, managed by the State of Hawaii Department of Health.
An ESPC is an alternative project delivery approach that allows a government agency to enter into a long‐term partnership with an energy service company to facilitate and accelerate energy conservation measures, or ECMs. The ECMs to be implemented will reduce the BWS’s annual electrical usage by about 8 million kilowatt hours (kWh), or 9 percent of the BWS's total purchased electricity.
The following Energy Conservation Measures (ECM) will be installed at 58 work sites, which are on BWS properties. At some sites, multiple ECMs will be installed.
