Ameresco Starts Cooperative Deployment of Solar+Energy Storage Project in Hawaii

American renewable energy project integrator Ameresco and utility company Bright Canyon Energy began construction of a solar+storage project at the U.S. Navy's Pearl Harbor-Hickam-West Joint Base, with the deployment of a 42MW/168MWh battery storage system.

The two companies held a groundbreaking ceremony for the project on Oct. 7, marking the groundbreaking for the kutypono solar+storage project, which is being deployed on Oahu, Hawaii's third-largest island. The project was first announced in June this year.

The kutypono solar+storage project, which includes a 42MW solar power facility and a 42MW/168MWh lithium-ion battery storage system, will provide power to the Hawaiian Electric Company (HECO) grid.

The project is being developed by kyoshipono Solar, a joint venture between Ameresco and Bright Canyon Energy. Bright Canyon Energy is a subsidiary of Arizona-based utility holding company Pinnacle West Capital.

Kyoshipono Solar has a 37-year land lease agreement with the U.S. Navy to provide power services to its Oahu base and will own and operate the project under a 20-year power purchase agreement (PPA) with Hawaiian Electric.

Hawaii Lieutenant Governor Josh Green said, "Today, we are taking significant steps to strengthen Hawaii's energy security and resiliency, and thanks to the Ewa community, the U.S. Navy, Hawaiian Electric, Ameresco, and Bright Canyon Energy, we are now one step closer to realizing Hawaii. One step closer to adopting the vision of 100% clean energy by 2045.”

According to industry media reports, in August this year, Clearway Energy opened a solar+storage project on Oahu, including a 39MW solar power facility and a 39MW/159MWh battery storage system, the first in Hawaii. Utility-scale solar+storage projects.

The project Ameresco plans to deploy is closely related to the two battery storage projects that AES has started construction on Maui, Hawaii, with a combined storage capacity of 360MWh.

Hawaii was an early U.S. state to deploy and adopt solar power, whether residential or utility-scale, in part because of the state's need to import expensive and polluting fossil fuels. More recently, there has been a growing interest in deploying battery storage systems in the state.

This includes utility-scale energy storage projects as well as residential energy storage projects, and Hawaiian Electric has launched a 10-year battery storage incentive program to encourage the deployment of residential energy storage systems alongside more solar power generation.
