Cost-Effective Pathways to 100% Renewables in Hawai‘i

Hawaiian Electric Company (HECO) is mandated by the state to meet a 100% renewable portfolio standard (RPS) by the end of 2045. To map out the transition, HECO needs to work with a diverse array of stakeholders, including state and local governments, private landowners, the tourism industry, renewable energy developers, consumer advocates, and environmentalists.

HECO hired E3, a Willdan Compnay, based on our experience in modeling electricity systems; our groundbreaking work in long-term, high-RPS planning in California and New York; and our unbiased, fact-based approach to working with utilities, regulators, environmentalists, and other stakeholders.

Using our Renewable Integration Solutions Model (RESOLVE), we provided several least cost plans for achieving a 100% RPS. HECO drew upon this work to develop the PSIP update, which it submitted to the Hawai‘i Public Utilities Commission in December 2016.
