Honolulu was selected during the first round of the Energy Transitions Initiative Partnership Project (ETIPP).
ETIPP is working with Honolulu and the Hawaiian Electric Company to evaluate optimal hybrid microgrid locations and identify potential microgrid participants to improve electrical infrastructure resilience to severe weather. The project will also produce a hybrid microgrid opportunity map that demonstrates distributed energy resource availability for future planning.

Hawaii is prone to severe weather conditions that have the potential to cause long-duration power outages. The island chain identified hybrid microgrids as one method to improve resilience. Microgrids are best suited to areas prone to prolonged outages during weather events, with clusters of customers and potential availability of renewable energy resources.
Under this project, Hawaiian Electric sought technical assistance through ETIPP to develop criteria for evaluating hybrid microgrids of less than 3 MW on the island of Oahu. Analyses of data provided by Hawaiian Electric, as well as data and models already being used by NREL and Sandia National Laboratories from prior work with Hawaiian Electric, were used to develop a map of potential hybrid microgrid clusters based on locationally specific site criteria.
The primary deliverable of the project was a map identifying potential locations given a set of criteria that stakeholders prioritized in the areas of criticality, vulnerability, and societal impact. The map is intended to guide developers to areas deemed suitable for further microgrid analysis and development.
Hawaiian Electric hopes to use the map to reduce initial barriers and complexities of developing microgrids on Oahu. The map accounts for the technical and practical viability of microgrid development.

The Hawaii Energy Policy Forum invites you to attend an upcoming webinar on September 7th, from 12-1 p.m. with Hawaiian Electric and NREL. The agenda topics for this meeting are the Hybrid Microgrid Map Pilot Project on Oahu and Renewable Energy Zone Engagement.
Renewable energy resources and a modernized electrical grid are key elements of Hawai''i''s transition from fossil fuels. Hawai''i''s energy transition supports multiple policy objectives such as energy security and resiliency, decarbonization, clean energy jobs, and lessening the impacts of oil price shocks and volatility. As electricity sales for electricity generated by renewable energy exceeds a combined 38 percent in Hawaiian Electric Company''s service territory on Oahu, Hawaii Island and Maui County, the essential role of communities to provide informed input and guidance on equitable and inclusive energy plans, policies, and strategies to better serve community needs is more important than ever.
To support its efforts in making its grid more resilient, HECO sought technical assistance to develop a hybrid microgrid map for O''ahu and was selected in a national solicitation under US Department of Energy''s Energy Transitions Initiative Partnership Program (ETIPP). Hawaiian Electric''s ETIPP project will result in a static map showing areas on O''ahu that are optimal for developing microgrids to build a more resilient electric grid. Hawaiian Electric is collaborating in this effort with the ETIPP Regional Partner, the Hawaiʻi Natural Energy Institute (HNEI), and the National Renewable Energy Laboratory, as the lead national laboratory overseeing the map design.
Grid-connected microgrids can be islanded during an outage from weather and other emergency events and continue to provide electricity through renewable generation, battery storage, and/or backup generators. Therefore, the intended purpose of a microgrid map is to reduce initial barriers and complexities to microgrid development by identifying areas where there is the greatest demand and urgent need to maintain critical services and infrastructure when the rest of the grid experiences electrical outages. In this webinar, our primary objective is to inform Hawaii''s leading energy stakeholders and HEPF members about the preliminary hybrid microgrid map design and seek input on the planned outreach and strategy for the upcoming community engagement effort.
Agenda Topic 2: Renewable Energy Zone Engagement
The webinar will also include a related discussion on Hawaiian Electric''s Hawaiʻi Powered Initiative, specifically the concept of designating renewable energy zones (REZ) in different regions on the island of O''ahu.
