Hawaiian Electric Phase 2 Renewable Energy Projects

The Hawaii State Energy Office (HSEO) is working to effectively and consistently communicate Hawaii’s collective energy vision to improve energy project development outcomes that contribute to the quality of life for everyone in Hawaii. In addition to widespread energy conservation and rooftop solar photovoltaic (PV), many new utility-scale renewable energy projects will be needed for Hawaii to eliminate its reliance on imported fossil fuels for electricity and produce 100% of its electrical power from indigenous renewable resources. Most of these projects will be needed on Oahu, which in 2019 consumed approximately 71.25% of Hawaii’s overall electricity, followed by Maui Nui (Maui, Lanai, and Molokai) at 12.25%, Hawaii Island at 11.5%, and Kauai at 5%.

This webpage was created to increase public awareness and access to information including opportunities for public input, as it becomes publicly available, on the 10 utility-scale solar PV plus storage projects and 3 utility-scale standalone storage projects being proposed on Oahu, Maui, and Hawaii Island under Phase 2 of Hawaiian Electric’s most recent competitive bidding process opened on August 22, 2019, and closed on November 5, 2019 — see Hawaii Public Utilities Commission (PUC) Docket No. 2017-0352. Hawaiian Electric is seeking renewable energy projects to provide generation and storage needed to retire: (1) by the end of 2022 as required by state law (Act 23, 2019) the state’s only coal-powered power plant which provides approximately 15% of Oahu’s energy, the 180-megawatt (MW) plant at Campbell Industrial Park owned and operated by AES; and, (2) by the end of 2024, the 38 MW oil-fired Kahului power plant in Kahului owned and operated by Hawaiian Electric which provides approximately 15% of Maui island’s firm power generation capacity.

Each new utility-scale renewable energy project must be submitted to the PUC for review and decision. An individual PUC docket has been or will be created for each utility-scale renewable energy project. The PUC docket process is in open forum that allows for public comment at any time in the proceeding. In addition, each project must obtain the requisite federal, state, and county permits and approvals; many of which offer opportunity for public comment.

HSEO’s Renewable Energy Projects Directory and Hawaiian Electric’s Renewable Project Status Board provide additional information on these Phase 2 projects and other utility-scale projects now under development or construction, approved by the PUC, or awaiting PUC approval throughout Hawaii, including those being developed under Phase 1 of Hawaiian Electric’s competitive bidding process.

Go to Solar Plus Storage Projects

All 10 of the solar PV plus storage projects on Oahu, Maui, and Hawaii Island are being developed by private renewable energy developers, some of which have reached agreement with Hawaiian Electric and some of which are currently negotiating power purchase agreements with Hawaiian Electric. On September 15, 2020, Hawaiian Electric submitted to the PUC for review and decision agreements for 7 of the solar PV plus storage projects. HSEO anticipates the agreements for the other 3 solar PV plus storage projects will be submitted to the PUC in 2020.

Go to Standalone Storage Projects

The 2 standalone storage projects on Maui and Hawaii Island are being developed by Hawaiian Electric, which submitted the projects to the PUC for review and decision in August 2020. The privately developed standalone storage project on Oahu was submitted to the PUC for review and decision on September 15, 2020.
