AES Hawaiʻi Launches Company’s First Solar plus Storage Facility on O‘ahu

Today, AES Hawaiʻi celebrated the launch of its West O‘ahu solar-plus-storage project in Kapolei – the company’s first facility to combine solar generation and battery energy storage on O‘ahu. The launch was commemorate with a blessing ceremony at the project site and reception at the nearby University of Hawai‘i-West O‘ahu campus.

Dignitaries joining AES Hawai‘i leadership at today’s commissioning of O‘ahu’s newest utility-scale solar project included Governor Josh Green, M.D., Honolulu Mayor Rick Blangiardi and University of Hawai‘i-West O‘ahu Chancellor Maenette K. P. Ah Nee-Benham.

Located on 66 acres of open University of Hawai‘i land, the West O‘ahu solar-plus-storage facility is generating 12.5 MW of clean energy for O‘ahu’s power grid, supported by a 50 MWh battery energy storage system, under a 25-year power purchase agreement with Hawaiian Electric at a cost of $0.115 cents per kilowatt-hour. The energy produced will reduce O‘ahu’s use of fossil fuels by 750,000 barrels of oil and the associated pollution and greenhouse gases emitted over the project’s lifetime.

Bernerd Da Santos, AES Executive Vice President and President, Global Renewables said the West O‘ahu project epitomizes AES Hawai‘i’s commitment to collaborate with community partners for the benefit of Hawai‘i’s long-term energy future.

“This is a momentous day for AES Hawai‘i as it is our first solar and storage project on O‘ahu and one that is providing a multitude of benefits over many years that extends far beyond the low-cost, clean energy we are generating for the people of O‘ahu,” said Da Santos. “We are partnering with a premier educational institution in the University of Hawai‘i-West O‘ahu, helping to reduce Hawai‘i’s dependence on imported oil and utilizing the land to support the island’s agricultural needs.”

Governor Green congratulated AES Hawai‘i on the launch of its first O‘ahu solar plus storage facility and the positive impact it will have in supporting the state’s clean energy goals while also combating the effects of climate change. “This project is one of many we welcome, as we make progress toward the Hawaiʻi Clean Energy Initiative, launched in 2008. We will continue the good work that is underway to make our islands petroleum-independent by the year 2045. Our administration is investing in contractor training programs to build a workforce with the technical expertise to support efforts like this.”

Mayor Blangiardi noted the project further strengthens the grid powering O‘ahu with clean, renewable energy while helping to reduce the island’s reliance on fossil fuels to generate electricity. “This project exemplifies the visionary leadership we absolutely need for O‘ahu’s energy future,” said Mayor Rick Blangiardi. “My heartfelt appreciation to Bernerd Da Santos, and his talented team at AES Hawai‘i for being great partners and truly caring about the people of Hawai‘i.”

The new project is key to the future of the University of Hawai‘i-West O‘ahu, as it is supporting the university’s net-zero energy goals while emphasizing the importance for students to embrace a clean energy future. Chancellor Ah Nee-Benham commented, “This partnership brings near- and long-term positive impacts to our community. The solar project embraces all of our institutional values of Po‘okela, Waiwai, Hana Lawelawe, Kaiāulu, and Mālama ‘Āina, and we look forward to the continued benefits that it brings for our students, faculty, staff, and their ‘ohana.”

The project’s launch and how it supports O‘ahu’s power grid aligns with the focus of Hawaiian Electric’s transition to utilize more clean energy resources to provide affordable electricity for homes and businesses island-wide. “This project represents another positive step in our state’s efforts to achieve our renewable energy goals. Our growing portfolio of renewable power and energy storage resources work together to provide reliability and energy security on our isolated island grid,” said Rebecca Dayhuff Matsushima, Hawaiian Electric Vice President of Resource Procurement.

AES Hawai‘i President Sandra Larsen noted that everything about West O‘ahu solar-plus-storage was done with the focus of supporting O‘ahu’s economy and environment over the long term. The project’s construction supported more than 120 jobs for local workers over a two-year period. In addition, the land is being utilized for sheep grazing to support the island’s agricultural and food production needs.

Larsen said, “The entire AES Hawai‘i team has done a wonderful job in bringing O‘ahu’s newest solar project to completion and is now generating renewable energy that people island-wide will benefit from for years to come. It’s especially gratifying because the overall priority of this innovative clean energy project is to help make O‘ahu a better, healthier and more affordable place for future generations to make a life here for their families.”
