Hawaii Statewide Energy Projects Directory

This Directory managed by the Hawaii State Energy Office (HSEO) provides information on many of the notable energy projects statewide in all stages of development and operation. It includes projects that will or could contribute to Hawaii’s transition away from fossil fuels as mandated by 2045 and the fossil fuel projects that provide critical electrical energy to the state until that transition is complete. HSEO updates this Directory as new information on individual projects becomes publicly available.


Learn About and/or Comment on the Projects in the Directory

HSEO encourages all Hawai’i residents to engage in the energy project planning process preferably in the early stages of project design and approval. For those projects submitted to the Hawaii Public Utilities Commission (PUC), public comments on individual projects can be submitted anytime to the PUC’s online Document Management System (DMS) by entering the Docket Number provided by the Directory for each project with a PUC docket. Docket links, when applicable, are also embedded in the directory.

About this Directory / Disclaimer

Projects listed in the Directory are based on public information only. Information on individual projects can be found in publicly available sources such as, but not limited to, regulatory agency filings and notices, meeting minutes, media publications, financial filings, landowner records, legislative materials, company communications, and other outlets. To the extent available, official sources of information are used to update the project information. Reasonable assumptions concerning a project’s status may be made based on the information available evidence demonstrating a project’s progress in key areas of development including site control, permitting, interconnection, power or fuel off-take, and construction. The Hawaii State Energy Office (HSEO) reserves the right to list projects on the Directory that warrant listing due to a projects’ innovation, uniqueness, and/or alignment with state priority initiatives. Projects may be removed from the Directory if no new information concerning project status is available after a reasonable duration. The Directory is not a complete list of all proposed and existing renewable energy projects in Hawaii. It does not include smaller solar/photovoltaic installations under 500 kilowatts (kW), such as those under net-energy metering, self-supply, or grid-supply interconnection programs. In addition, projects subject to an open or ongoing competitive solicitation may not be listed due to outstanding project uncertainty. Some projects may not be listed simply because little or no public information has been made available. Not all projects on the Directory will be developed and become operational for a variety of reasons. Some project announcements may be premature or unfounded, and many proposed projects are discontinued for a variety of reasons. As the Directory is based on publicly available information, HSEO cannot guarantee the accuracy or completeness of all information. In certain cases, attempts have been made by HSEO to verify information that has been publicly reported. Interested stakeholders are encouraged to contact individual project developers for the most accurate and current project information. The Directory does not represent an endorsement of any specific project or company by HSEO or the State of Hawaii. HSEO strives to provide the most accurate information on each project and encourages users to send project updates and/or corrections to [email protected].
