Pearl Harbor-Hickam Base to Add Solar

A combined solar and battery storage system will be built at the Joint Base Pearl Harbor-Hickam West Loch Annex in Hawai‘i. 

Once operational, the project is designed to deliver 42 MW of clean, renewable energy to Hawaiian Electric’s (HECO) grid on the island of O‘ahu. 

Ameresco, Inc. and Bright Canyon Energy hosted a groundbreaking and blessing ceremony for the Kūpono Solar Project on October 7. Construction on the Project is expected to be completed in early 2024.

Attendees at the event heard from U.S. Senator Mazie Hirono, Lt. Governor Josh Green, and Meredith Berger, Assistant Secretary of the U.S. Navy for Energy, Installations, and Environment.

Using approximately 131 acres of Federal land, the Kūpono Solar Project will feature the installation of a 42 MW/168 MWh (four-hour duration) of lithium-ion battery storage system. The batteries are designed to store solar energy beyond sunset hours, enabling the project to deliver sustainable, renewable energy to power approximately 10,000 homes on O‘ahu. Additionally, once fully operational, the project is expected to reduce more than 50,000 tons of carbon dioxide annually from Hawai‘i’s environment.

“Today, we are taking significant strides to strengthen our state’s energy security and resilience, and thanks to the ‘Ewa community, Navy, Hawaiian Electric, Ameresco and Bright Canyon Energy, we are now steps closer to reaching Hawai‘i’s renewable energy vision of achieving 100% clean energy by 2045,” said Lt. Governor Josh Green in a statement. “Kūpono Solar is a landmark initiative for us that will not only benefit our state’s economy but will also bolster our sustainability efforts and local communities through stable, affordable energy, innovative technology and job creation.”

Kūpono Solar will own and operate this solar and battery project under a 20-year power purchase agreement with Hawaiian Electric.
