Integrated Grid Planning

Path to Hawaii Powered

Our work to move toward a Hawaii Powered future is guided by a process called Integrated Grid Planning, or IGP. The IGP process brings many people together to build a safe, resilient and reliable grid from local, renewable energy sources with various technologies and scales. A resilient grid can better withstand severe events, including weather-related disasters, and enable faster recovery.

Integrated Grid Plan

The Integrated Grid Plan outlines a pathway to a clean energy future. It proposes actionable steps to decarbonize the electric grid on the State of Hawaii's timeline, with a flexible framework that can adapt to future technologies.

Hawaiian Electric is now embarking on the second cycle of the IGP process, which will occur from 2026 through 2030.

The IGP was accepted by the PUC on March 7, 2024.

A cyclical process

The IGP process is a multi-year, multi-cycle process. It is designed to be iterative and collaborative, with annual updates and ongoing stakeholder and community engagement to develop and refine the plan. This means that planning and implementation is not a one-time event, but an ongoing, cyclical process to work toward the state’s goal of 100% renewable energy by 2045.

First cycle: The first planning cycle began in 2018 and concluded with the acceptance of the Integrated Grid Plan by the Public Utilities Commission in March 2024.
Second cycle: Hawaiian Electric is now in the second cycle of the IGP process. In August 2025, Hawaiian Electric filed a draft workplan for this second cycle with the Public Utilities Commission.

This second cycle will occur over three years followed by review by the Public Utilities Commission. Hawaiian Electric’s vision for the second cycle is to carry forward and build on the collaborative spirit of the first cycle, which represented more than five years of partnership with stakeholders and community members across the islands.

Together, we can work toward the state’s goal of an energy system that emits zero net carbon emissions and use 100% renewable resources.
