ETIPP and Microgrids

About the Energy Transitions Initiative Partnership Project

Hawaiian Electric was selected last year as partner in the U.S. Department of Energy's (DOE) Energy Transitions Initiative Partnership Project (ETIPP) to improve energy resilience and combat climate change. As part of the partnership, Hawaiian Electric is helping to identify areas on O‘ahu that are optimal for developing microgrids to build a more resilient electric grid. Microgrids serve areas that are connected to the electric grid yet can be islanded during an outage to continue providing electricity through a variety of resources, including solar panels, a battery and/or backup generator.

Hawaiian Electric hopes to reduce initial barriers and complexities with a map that takes into account the technical and practical viability of microgrid development. Microgrids are best suited to areas prone to prolonged outages during weather events, with clusters of customers and potential availability of renewable energy resources. The map would allow developers to contact potential microgrid participants and work with Hawaiian Electric to apply for the development of a specific microgrid.


Provide customers with a map identifying areas that are good candidates for hosting hybrid microgrids, to improve electrical infrastructure resilience to severe weather.

Evaluating Hybrid Microgrid Hosting Locations


Where are the critical loads, facilities and services?

  • Emergency: emergency shelters, fire stations, EOC
  • Medical: hospitals, out-patient facilities, surgical centers, skilled care facilities
  • Infrastructure: water sources & treatment, internet exchange points, transmission towers, dams, bridges, ports, airports


What parts of the grid currently and are projected to endure the longest or most frequent outages?

  • Natural hazards and inaccessibility: flood, sea-level rise (through 2050), landslide, tsunami, remoteness
  • Outages (2011-2021)


What other locations would significantly impact communities if they lost power?

  • Residential care facilities, community homes
  • Schools, daycares, libraries
  • ALICE program
  • Disadvantaged communities
