Mililani Solar + Storage
The 39 MW Mililani Solar power plant is paired with a 156 MWh battery storage system and includes over 123,000 photovoltaic panels.
Clearway in Hawai’i
Since 2019, students have participated in our Hawaii summer internship program, in partnership with Kamehameha Schools.
Participants experience clean energy career opportunities through training sessions with the Clearway team, from engineering to operations.
By partnering with the community, we grow Hawaii’s clean energy workforce while helping the Aloha State achieve its goal of using 100% renewable energy.

Leading Hawaii's 100% clean energy transition
Just before Hawaii closed its last coal plant, it flipped the switch on Mililani Solar, O’ahu’s first solar + storage power plant. The 39 MW solar and 39 MW storage site provides reliable and low-cost clean power even after the sun goes down.
Committed to leaving Hawaii better for the next generation
David Ige
Governor of Hawai'i
Renewable energy is critical to Hawai‘i to be more affordable and resilient. We are a step closer to that goal today because of the Clearway team, which understood the urgency and stepped up to deliver their project ahead of schedule.
Featured solar projects
Providing Hawai’i homes and businesses with reliable low-cost power.
Waiawa Solar + Storage
The 36 MW solar farm with 144 MWh of battery storage is located on Kamehameha Schools’ lands in Waiawa in Central O‘ahu. Waiawa generates enough clean electricity to power more than 7,600 homes each year.
Kawailoa Solar
The 49 MW Kawailoa Solar project uses nearly half a million solar panels and is the largest solar project in the state to date, sited on former sugar cane land owned by Kamehameha Schools.
Waipi‘o Solar
The 45.9 MW Waipi‘o Solar project consists of over 160,000 panels on a former cattle pasture owned by Clearway in Central O‘ahu. The Waipi‘o project will also use sheep grazing during operations to help manage vegetation while supporting local agriculture.
Mililani Solar II
The 14.7 MW Mililani Solar II project consists of over 150,000 solar panels and is constructed on former pineapple land owned by Clearway. Located within the Mililani Agricultural Park, the project operates alongside active farming operations.
