Hawaiian Electric energized a second mobile substation in the Lahaina area Tuesday as crews work to restore a majority of West Maui customers by this weekend and continue to safely rebuild sections of Maui's electric grid.
Connecting a mobile substation to the grid is a complex process that takes time to safely connect customers, HECO said in a news release Tuesday. Substations step down power from high-voltage transmission lines to lower-voltage distribution lines that serve neighborhoods. Crews are working to build new distribution lines from the mobile substation to complete restoration to customers in the Launiupoko to Olowalu area.
In Upcountry, crews are working to address pocket outages affecting about 50 customers. Specialized cable and other supplies needed for additional repair work are expected to arrive on Maui this week.
About 1,800 customers in West Maui continue to be without power. More than 80 percent of the customers who lost electricity have their power back on.
