Renewable Energy Procurement (RFP Docket No. 2017-0352) — Resource Procurement by Island

RESOURCE PROCUREMENT BY ISLAND

Oahu | Maui | Hawaii Island

Hawaiian Electric’s three stages of RFPs for renewable dispatchable generation for Oahu, Maui, and Hawaii Island result in Power Purchase Agreements (“PPAs”) that the Commission reviews. PPAs represent an agreement for Hawaiian Electric to purchase energy from a power plant that a developer builds and operates over a contract term, typically 20 to 30 years.

The following tables provide a list of the resources procured through the RFPs described above, including relevant dockets and developer websites for more information on each resource. Prior to contract submission, Hawaiian Electric and the developer engage in “PPA Negotiations” to develop a contract. Once a contract is submitted to the Commission, it is “Under PUC Review” until approved by the Commission, “PPA Approved” after the Commission’s approval and during construction, and “In Service” once online and providing energy.

Projects that have withdrawn from consideration are not included. Sizes are presented in megawatts (“MW”) for capacity specifications, such as the size of solar panels, and in megawatt-hours (“MWh”) for energy specifications, such as the size of batteries. A project that is 10 MW in capacity could provide 50 MWh in energy if dispatched at full capacity for five hours, for example. A typical household in Hawaii uses approximately 537 kilowatt-hours (“kWh”; 1,000 kWh equals 1 MWh) per month.

Note that this is not a comprehensive list of all renewable resources by island, rather a list of resources procured and either completed or in the pipeline since 2017 through Hawaiian Electric’s competitive bidding process in Docket No. 2017-0352. See Hawaii State Energy Office’s Hawaii Statewide Energy Projects Directory and Hawaiian Electric’s Sustainability Reports for additional directories of renewable energy projects in the State.
