Background | Upcoming Events | Past Events | Topic Tracks | Frequently Asked Questions | Key Orders (General) | More Information


Distributed Energy Resources (“DERs”) are small-scale resources that enable customer participation in the generation and delivery of electricity service. The most common DERs used for electricity generation are solar photovoltaic panels, which are often paired with battery energy storage systems.

In September 2019, the Hawaii Public Utilities Commission opened Docket No. 2019-0323 to investigate the technical, economic, and policy issues associated with DERs and rate design, as they pertain to the Hawaiian Electric Companies. Docket No. 2019-0323 is divided into three tracks, covering topics in 1) Advanced Rate Design (“ARD”), 2) DER Programs, and 3) Technical issues.

For more information regarding Hawaiian Electric’s Time of Use Study, which launched on February 1, 2024, please see the Commission’s TOU Rate Study Fact Sheet, also available in the Advanced Rate Design page.

For more information regarding Hawaiian Electric’s new DER programs, the Smart DER Tariff and Bring-Your-Own-Device (“BYOD”) Tariff, which launched for enrollment on April 1, 2024, please see the Commission’s DPS Phase 3 Decision and Order Summary, also available in the DER Programs page.
