(Reuters) - Electricity provider Hawaiian Electric on Monday laid out a plan to fortify the power grid to help reduce the risk of a wildfire started by its equipment.

The utility has faced intense scrutiny in the past for its role in the deadly 2023 Maui wildfire. The fires killed over 100 people, destroyed the historic coastal town of Lahaina and caused damage estimated at $5 billion.

Several destructive U.S. blazes in the past have been linked to power infrastructure, leading to devastating financial and legal problems for utilities.

Hawaiian Electric said its wildfire safety plan would cost about $450 million from 2025 to 2027, with $137 million already budgeted for work this year.

The company added that some of the costs have already been funded through existing programs, including a federal grant it received in 2024 for grid resiliency.

Shares of the company were up about 1.2% in trading after the bell.
