HECO Announces Grid Modernization Timeline for Maui

Hawaiian Electric has released its updated grid modernization plan for Maui County, outlining infrastructure investments that will increase the island's capacity for distributed solar.

Planned Upgrades

The multi-year plan includes: - Substation capacity upgrades in South and West Maui - Advanced inverter integration requirements - Distribution automation systems - Enhanced monitoring and control systems

Impact on Solar Customers

These upgrades are expected to reduce interconnection delays and allow more homes to install solar without expensive grid upgrade requirements.

Timeline

"We expect the first phase of improvements to be complete by mid-2025," said a HECO representative. "Homeowners in currently constrained areas should see improved approval times starting later this year."

Investment

HECO is investing approximately $50 million in Maui County grid improvements over the next three years, funded through a combination of ratepayer funds and federal grants.
