If true, the "downed power lines caused the Maui fires" theory is not valid.

(Reuters) -Hawaiian Electric’s shares jumped more than 40% on Monday after the utility said its power lines in West Maui had been shut down for more than six hours before wildfires started in the area during the afternoon.

...The county said downed power lines started the wildfires that destroyed the historic town of Lahaina earlier this month, killing at least 115 people and displacing hundreds more.

Hawaiian Electric said on Monday that a morning fire on Aug. 8 caused by power lines that fell in high winds was subsequently reported “100% contained” and later declared “extinguished” by the Maui County Fire Department.

The utility said another afternoon fire started in the same area more than six hours after all of its power lines in West Maui had been de-energized, which could not be contained by the fire department and spread out of control toward Lahaina.

“We were surprised and disappointed that the County of Maui rushed to court even before completing its own investigation,” said Shelee Kimura, president and CEO of Hawaiian Electric.
