Hawaiian Electric Stage 1 and 2 Renewable Energy Projects
Intro
This webpage was created to increase public awareness, access to information, and opportunities for public input on the 20 utility-scale solar PV plus storage projects and utility-scale standalone storage projects being proposed on Oahu, Maui, and Hawaii Island to reach 100% renewable energy generation by 2045. In the near term, Hawaiian Electric is seeking these projects 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) AES coal plant at Campbell Industrial Park; 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. VIEW A MAP OF THE PROJECTS
Starting in 2017, Hawaiian Electric issued two Stages of competitive bidding for these projects. Stage 1 produced 8 utility-scale solar PV plus storage projects and Stage 2 produced to date 9 utility-scale solar PV plus storage projects and 3 utility-scale standalone storage projects. Of the 20 total projects in both Stages, 18 would be built, owned, and operated by private developers. Hawaiian Electric would build, own, and operate the Waena and Keahole battery storage projects. The 20 projects are proposed on Hawaii Island (4 projects), Maui (5 projects), and Oahu (11 projects). All 20 projects are estimated to be completed by the end of 2023, with many estimated to be completed in 2022 including all Stage 1 projects.
Widespread energy conservation and rooftop solar photovoltaic (PV) installations are necessary, but it will not get us to 100% renewable energy generation with a reliable electric grid. Many new utility-scale renewable energy projects are needed for Hawaii to generate 100% of its electrical power from locally sourced, 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%.
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 listed on this website. 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 projects and other utility-scale projects now under development or construction, approved by the PUC, or awaiting PUC approval throughout Hawaii.
