Lawmakers probing the cause of last month’s deadly Maui wildfire did not get many answers during Thursday’s congressional hearing on the role the electrical grid played in the disaster.

Still, the president of Hawaiian Electric — Maui’s sole electricity provider — promised to gather and provide more details about what happened Aug. 8, including when the power stopped flowing through downed power lines in Lahaina and when the decision was made to trigger a procedure designed to make sure that broken lines were not reenergized.

Shelee Kimura also said the utility doesn’t have the right or responsibility to clear dry brush or other vegetation on private property — even if it is in the right-of-way, directly underneath power lines — unless the plants or trees are tall enough to potentially contact the lines.

The fire in the town of Lahaina killed at least 97 people and destroyed more than 2,000 buildings, mostly homes. It erupted at 6:30 a.m. when strong winds appeared to cause a Hawaiian Electric power line to fall, igniting dry brush and grass near a large subdivision.

Aerial and satellite imagery reviewed by The Associated Press show the gully where the fire reignited later that afternoon has long been choked with plants and trash, which a severe summer drought turned into tinder-dry fuel for fires.
