When high winds on Maui brought down power poles, the electrical wires were bare, uninsulated metal that could spark on contact with the dry grass below.
In the first moments of the Maui fires, when high winds brought down power poles, slapping electrified wires to the dry grass below, there was a reason thein long, neat rows — those wires were bare, uninsulated metal that could spark on contact.
Compounding the problem is that many of the utility’s 60,000, mostly wooden power poles, which its own documents described as built to “an obsolete 1960s standard,” were leaning and near the end of their projected lifespan. They were nowhere close to meeting a 2002 national standard that key components of Hawaii’s electrical grid be able to withstand 105-mph winds.
“We’ve been executing on a resilience strategy to meet these challenges, and since 2018, we have spent approximately $950 million to strengthen and harden our grid and approximately $110 million on vegetation management efforts,” the company said. “This work included replacing more than 12,500 poles and structures since 2018 and trimming and removing trees along approximately 2,500 line miles every year on average.
