Hawaiian Electric launches biggest renewable‑energy procurement for Hawaii’s grid

Hawaiian Electric has filed an Integrated Grid Planning Request for Proposals (IGP RFP) with the state Public Utilities Commission, opening one of the largest procurement processes in the islands. The utility seeks roughly 1,650 GWh of variable renewable power (solar and wind), 465 MW of grid‑forming resources that combine solar generation with battery storage, and 111 MW of firm, dispatchable generation. Projects are slated for commissioning between 2031 and 2034. In addition, Hawaiian Electric is asking for separate regulatory approval to add up to 500 MW of fuel‑flexible firm generation on Oʻahu.

The plan is part of Hawaii’s broader goal of achieving 100 % renewable electricity by 2045 and is intended to modernize the generation fleet, cut reliance on oil, and lower customer electricity costs. CEO Scott Seu said the expedited procurement will “drive competition, evaluate all options, and more rapidly build a portfolio that meets efficiency, reliability and lower carbon emissions at the least cost.” The deadline for RFP submissions is today, and the utility highlighted existing projects such as the 60 MW Kuihelani Solar‑plus‑Storage facility with a 240 MWh battery that already supplies about 15 % of Maui’s demand.
