Who Provides Utilities in Hawaii?

Hawaiian Electric covers every Oahu city we've sampled — Honolulu, Kailua, Kaneohe, Waipahu and Pearl City all run on it. Hilo, on the Big Island, runs on a sister company, Hawaii Electric Light, instead — each Hawaiian island effectively runs its own separate grid. Hawaii has no retail electric market.

One company, separate grids island by island

Hawaiian Electric delivered electricity at every sampled address on Oahu — Honolulu, Kailua, Kaneohe, Waipahu and Pearl City. On the Big Island, the utility is Hawaii Electric Light, a sister company under the same parent, serving Hilo. Because Hawaii's islands aren't connected to each other or to a mainland grid, each island effectively runs its own separate, self-contained electric system even when the same corporate parent is behind it.

Hawaii doesn't run a retail electricity market, so there's no supplier to shop for — whichever island utility holds your address delivers the power directly. Gas and water coverage isn't consistently confident yet in our sampling for these cities, so those accounts are worth confirming individually at the address level.

Hawaii utility questions, answered

Who is my electric company in Honolulu?

Hawaiian Electric delivered electricity at every sampled Honolulu address, along with Kailua, Kaneohe, Waipahu and Pearl City — the whole Oahu portion of our sample. Since Hawaii doesn't have retail electric choice, that's the utility you'd sign up with directly.

Is Hawaii Electric Light the same as Hawaiian Electric?

They're sister companies under the same parent, but Hawaii Electric Light serves the Big Island (Hilo, in our sample) while Hawaiian Electric serves Oahu. Because the islands aren't connected by a shared grid, they function as genuinely separate utilities.

Does Hawaii have retail electric choice?

No — Hawaii doesn't run a deregulated electricity market. Whichever island utility holds your address, Hawaiian Electric or Hawaii Electric Light, is who you sign up with directly, with no competing supplier to shop for.

Who provides gas and water in Hawaii cities?

Our sampling doesn't yet have confident gas or water data for these Hawaii cities — coverage varies by address in ways we can't generalize citywide. Check the lookup for a confirmed answer at your specific address.
