Timeline
Renewable energy zones are long-term investments that require extensive planning and coordination. Hawaiian Electric dedicates significant resources to environmental review, permitting and building the transmission needed to safely carry renewable energy to homes and businesses across the island. Taking the time to do this work upfront helps ensure projects are built efficiently and deliver lasting benefits to our communities.
2022-2025 Early outreach and research
Hawaiian Electric gathers broad public input on local opportunities and challenges for potential energy projects to help identify potential renewable energy zones. Hawaiian Electric also gathers technical data (for example, generation potential, land availability and climate risk exposure) to inform early mapping of renewable energy zones.
2026 Initial evaluation and selection
Hawaiian Electric evaluates potential renewable energy zones against criteria including community input and technical data. Hawaiian Electric files initial renewable energy zones with the Public Utilities Commission for review and approval to move forward.
2027-2029 Planning and development
Engineering and siting studies, environmental surveys, right-of-way planning and community engagement. Planning continues for additional renewable energy zones.
2029-2035 Design and construction
Final design, permitting, procurement, construction, testing and commissioning. Development advances for future renewable energy zones.
2035-2045 Ongoing buildout
Continued design, construction and integration of renewable energy zones statewide.
2045 Net-zero grid
Hawai'i achieves its net-zero carbon emissions goal.
