Hawaiian Electric Adds Clean Energy Facilities

Hawaiian Electric Company will add clean energy facilities, including two located on the island of O‘ahu. 

The Pu`uloa Energy installation is designed to generate 99 megawatts (MW) of renewable power leveraging clean fuels, including biodiesel and biogas fuels. The Pu`uloa Solar project will provide Oahu with an additional 6.4 MW of solar generation combined with 6 MW/30 megawatt hours (MWH) of energy storage.

Ameresco, Inc., a clean technology integrator specializing in energy resiliency, announced it was selected for Hawaiian Electric Company’s clean energy procurement initiative.

Pending successful negotiation of a power purchase agreement with Hawaiian Electric and approval by the Hawaii Public Utilities Commission, Pu`uloa Solar and Pu`uloa Energy are expected to begin supplying electricity to customers by Q3 2026 and Q4 2027, respectively. 

“These projects align with the energy priorities and policies set forth by the state of Hawaii, including the 100 percent renewable energy and carbon neutral goals by 2045 and also strongly support the Navy’s goals to bring energy resiliency to Pearl Harbor,” said Nicole Bulgarino, Executive Vice President of Ameresco, in a statement. “We are committed to working with the community as we move forward with these exciting projects that are designed to deliver clean energy to O‘ahu.”

Ameresco is also working with the Department of Navy towards a second 37-year land lease with the Navy at Joint Base Pearl Harbor Hickam (JBPHH) to provide critical energy resiliency upgrades. This newest lease encompasses multiple parcels at JBPHH and builds on a current lease Ameresco has with the Navy in support of Kūpono Solar.

Kūpono Solar is under construction and when commissioned, is expected to bring 42 MW of solar generation and 42 MW / 168 MWH (four-hour duration) of energy storage that will be used by Hawaiian Electric’s customers.
