The Public Utilities Commission held its second informational meeting on Hawaiian Electric’s Wildfire Mitigation Plan on April 25, 2025, focusing on strategies to reduce wildfire risks associated with power lines across the state. A key discussion point was the ranking of transmission circuits by wildfire consequence risk, with particular emphasis on the high-risk lines near Waikoloa Village.

During the meeting, a representative highlighted that the transmission lines adjacent to Waikoloa Village are ranked fourth in the state for wildfire risk, making them the most dangerous on Hawaii Island. The lines, which carry 69,000 volts, pose a significant threat if they fail and ignite surrounding areas.

The meeting also addressed four mitigation techniques proposed in the safety strategy. The first, Enhanced Fault Detection (EFT), is already in place and received positive feedback. The second technique, Public Safety Power Shutoff (PSPS), was discussed with concerns raised about its impact on local water supply. Waikoloa Village relies on four wells for water, but only two have backup generators, which could lead to a loss of water pressure for firefighting efforts during PSPS events.

The third technique, covering conductors, was noted as not applicable for the high-voltage lines in the area, as covered conductors are not produced for voltages above 42,000 volts. Lastly, the option of undergrounding power lines was mentioned, but the estimated cost of $60 million makes it an unlikely immediate solution.

Participants expressed a desire for more specific information regarding the local power lines and circuits, particularly how PSPS events would be managed in relation to water supply. The meeting concluded with a call for further clarity on these issues to enhance community safety and preparedness against wildfires.
