Clean Energy Hawaii

Self-Build Projects

Under the Competitive Bidding Framework rules approved by the PUC, Hawaiian Electric may propose "self-build" projects – developed, constructed and owned by the utility – to meet generation and/or capacity needs across its service territories.

As a result, in response to the August 2019 Request for Proposals, Hawaiian Electric submitted proposals to develop five grid-tied battery energy storage systems (BESS) on Oahu, Maui and Hawaii Island.

Grid-tied energy storage is an important component of a clean, sustainable energy future. To meet the state’s renewable energy goal of 100 percent by 2045, grid-tied energy storage will support system reliability as more variable renewable energy is added to the grid.

BESS can provide multiple grid benefits including load-shifting and contingency support.

  • Load-shifting – stores energy during periods of low customer demand, for use during early morning hours and at night when electricity demand is at its highest. This type of BESS enables the electric grid to accommodate more renewable sources, such as solar and wind, while it displaces thermal generation and helps lower emissions.

  • Contingency – allows stored energy to be sent to the grid as a quick response to an unexpected event such as a sudden drop in energy production from wind, solar, or a thermal power plant. This quick response capability improves grid reliability and reduces the likelihood of customer outages.

Public comments on the projects will be accepted until May 14, 2020 and submitted as part of the PUC application process. If these projects are chosen through the RFP process, a PUC application will be submitted, and a second round of public comments will be solicited and shared as part of the docket associated with the project application.

Please see below for details on each proposed battery energy storage system (BESS), by island.

Oahu

On Oahu, new renewable generation and storage is needed to replace the 180-megawatt, coal-fired AES Hawaii plant in Campbell Industrial Park due to close by September 2022. The AES plant is the largest single generator on Oahu, meeting 16 percent of peak demand. Hawaiian Electric proposes to build load-shifting (LS) battery storage systems at its Kahe Power Plant (read the draft EA here) and on industrial land near Kalaeloa adjacent to its CEIP Substation. The CEIP BESS will also serve as a contingency battery.

Maui County

On Maui, new renewable generation and storage is needed for the planned retirement of Kahului Power Plant by the end of 2024. Hawaiian Electric proposes to build a load-shifting BESS on its property near the Central Maui landfill.
