Clearway Energy Group is to supply electricity to Hawaiian Electric Company from two solar farms totalling 75MW on the island of Oahu.
The projects are the 39MW Mililani 1 and 36MW Waiawa facilities, which will both include energy storage capabilities.
The power purchase agreement between Clearway and Hawaiian Electric Company has been sent to the Hawaii Public Utilities Commission for review.
Clearway said the two projects are in addition to three plants that are currently under construction and set to come online later this year.
In total, the five solar farms will have installed capacity of 185MW, it said.
Clearway Energy Group chief executive Craig Cornelius said: “We are proud of the work Clearway is doing with Hawaiian Electric and all of our partners in Hawaii to expand renewable energy in the state.
“Hawaii is already a leader nationally in renewable development, and we’d like to thank Hawaiian Electric, Governor Ige, the legislature, and the PUC for their leadership and vision in setting the state on a course to be 100% powered by renewables by 2045.”
