Hawaii

Who serves its customers, 2025

Customers of full-service and energy-only providers, as EIA counts them; delivery-only customers are the same people, so they are not counted twice.

Average price by sector, 2025

Revenue from every kind of service over sales counted once, as EIA computes its state averages.

Capacity and generation by fuel

Utilities

A utility with too few reported figures for its own page is listed here with what it reported.

Power plants (76)

Customer-owned generation (net metering)

Before 2023, EIA reported storage paired with photovoltaic inside the photovoltaic group; from 2023, batteries are their own group, paired with photovoltaic or not. Neither is added into photovoltaic here.

Distributed generation that is not net metered

A different arrangement: customer-sited or utility-owned generation that is paid or credited some other way, or not at all. EIA reports it separately, and it is not added to the net metering figures.

We do not restate net metering rules, which change. The rules are with Hawaii Public Utilities Commission · the DSIRE policy database (NC Clean Energy Technology Center)

Community solar

Hawaii has 5 community solar projects serving customers, 4.3 MW-AC in all, in the National Laboratory of the Rockies' list as of September 2026.

In queue: market tracking, not a registry

The laboratory also tracks 52.0 MW-AC as in queue here as of September 2026: awarded, under construction, or likely to come online in the next few years.

Projects in queue change without notice, and many are never built. This figure is kept apart from the capacity serving customers and never added to it.

These counts and capacities are our own sums of the laboratory's project list; its license keeps us from publishing a copy of the list itself. About the dataset
