Hawaiian Electric reported progress in 2025 on its multiyear upgrades to the downtown Honolulu and Chinatown underground power network, part of a program that began in 2018 and was accelerated after a June 2024 outage. The company said 2025 work included replacing 5.3 miles of underground cable on two separate circuits, inspecting all 187 manholes and all 140 vaults, replacing six network transformers/protectors and two network protectors, and replacing two manhole top slabs. Hawaiian Electric said most work is expected to be completed by 2029, with total spending by the end of the decade projected at about $183 million, and that 2026 work will include additional cable replacement, substation equipment upgrades, and new infrastructure installation.
