Our Vision & Commitment

Microgrid Services Tariff

The Public Utilities Commission, in Order No. 36481, created two working groups: a Market Facilitation Working Group and an Interconnection Standards Working Group.

The Market Facilitation Working Group will work towards:

  • Draft Microgrid Services Tariff ("MGS Tariff") language to enable microgrids that provide backup power during grid outages
  • Proposed compensation for the use of the Hawaiian Electric Companies' distribution system, if necessary
  • Recommendations to modify existing programs, and/or new programs or services, if necessary, to support microgrid development
  • Justification for compensation for clearly demonstrated benefits to non-participants, if necessary

The Interconnection Standards Working Group will work to draft language modifying Rule 14H regarding interconnection and islanding/reconnection of microgrids. The proposed interconnection changes should support microgrid and backup power applications under existing tariffs and the MGS Tariff. Consistent with Act 200, the new section of Rule 14H should standardize and streamline interconnection requirements and processes for existing and new microgrids.
