WASHINGTON, D.C. — Sen. Mazie K. Hirono (D-Hawaii) highlighted the efforts of Kauai Island Utility Cooperative and Hawaiian Electric to deploy renewable energy plus storage facilities across the state at a Senate Energy and Natural Resources Committee hearing on energy storage Tuesday.

Hirono also spoke about her visit to the Lawai Solar Energy Plus Storage Facility on Kauai in April. Currently the largest solar generation plus storage project in the world, the Lawai facility generates 11 percent of Kauai’s power and can serve as much as 40 percent of Kauai’s evening peak power demand.

“Hawaii is on the leading edge of incorporating renewable power and energy storage,” she said. “Of course, Hawaii is not connected to any other state’s grid, we’re kind of on our own.”

Hawaiian Electric recently received approval for six new solar and storage projects to provide 247 megawatts of solar energy with almost 800 megawatt hours of storage — enough to power 105,000 homes per year while eliminating the use of more than 48 million gallons of imported fossil fuel.

Hirono said Hawaii was the most imported fossil fuel dependent state in the country, and probably had the highest electricity rates in the country, possibly with the exception of Alaska.

She said altogether, KIUC gets 50 percent of its power from renewable sources, and it expects to reach 60 percent renewable power by the end of this year with another combined solar and battery storage system at Pacific Missile Range Facility, Barking Sands Naval Base.

KIUC President and CEO David Bissell said he appreciated Hirono’s support of their efforts.

“So far in 2019 we are achieving 55 percent renewable generation and could be as high as 80 percent within five years if all projects are completed on schedule,” he said. “KIUC’s success can be attributed to the combination of active engagement of our members, strategic leadership from our Board of Directors, employee innovation and strong support from the local, state and federal levels.
