Hawaii contracts with Ameresco for efficiency, renewable power for sustainability commitment

Ameresco, Inc. (NYSE:AMRC), a leading energy efficiency and renewable energy company, announced that the company is working with Hawaii’s Department of Accounting and General Services (DAGS) to implement $17.4 million in upgrades as part of an Energy Savings Performance Contract (ESPC).

Over the 20 year term, the project is expected to lower costs by $28 million; and save DAGS more than a million dollars in the first year by reducing energy and water consumption and increasing renewable energy at 13 facilities.

The project includes 22 energy conservation and renewable energy measures across 33 state-owned buildings on five islands: Kauai, Oahu, Molokai, Maui and Hawaii’s Big Island.

The approximate two year design build implementation period will include replacing or retrofitting 13,000 light fixtures, expanding the energy management system (EMS) to include 2,750 control points, installing seven new chillers with art bearing-less compressors, and replacing 53 transformers with premium efficiency custom-wound transformers. The new photovoltaic (PV) arrays will consist of over 3,370 solar panels connected to 17 inverters. The solar arrays are expected to generate about 1.3 million kilowatt hours a year, helping facilities lower dependence on electricity produced from fossil-fueled power plants.

The annual emissions reduction is expected to be approximately 5.6 million pounds of CO2, 14,200 pounds of SO2, and 12,700 pounds of N2O.
