Rate Schedules & Tariff Analysis
Hawaiian Electric commercial bills combine a base energy charge, a demand charge ($/kW), a fixed customer charge, and a stack of PUC-approved adjustments. The single largest variable adder on Oahu is the Energy Cost Recovery Clause (ECRC) at $0.184490/kWh (Jan 2026), reflecting imported-fuel costs; the RBA Rate Adjustment adds 21.27% to most charges. Because of these, Hawaii has the highest commercial electricity rates in the US, which makes load management, demand reduction, and on-site solar+storage unusually valuable.
Hawaiian Electric Company Rate Schedule List
| Schedule | Applicability |
|---|---|
| Schedule J | Medium commercial demand (<300 kW) |
| Schedule P | Large power (>=300 kW) |
| Schedule DS | Large power directly served |

| TOU-J / ARD TOU J | Medium commercial TOU |

Hawaiian Electric Company Data Access FAQ
What commercial rate schedules does Hawaiian Electric offer on Oahu?▾
The main C&I schedules are Schedule G (small, non-demand), Schedule J (medium, general service demand, under 300 kW), Schedule P (large power, 300 kW and above), and Schedule DS (large power directly served at primary voltage). Time-of-use variants (ARD TOU G/J, TOU-P) are also available. As of January 1, 2026, Oahu effective energy charges are about $0.337/kWh (G), $0.282/kWh (J), and $0.250/kWh (P), each before the ECRC and other surcharges.
Why are Hawaiian Electric bills so high, and what drives monthly changes?▾
Hawaii has the highest electricity rates in the US because it relies heavily on imported fuel. On top of base rates, bills carry an Energy Cost Recovery Clause (ECRC) - $0.184490/kWh on Oahu in January 2026 - that tracks fuel costs and changes monthly, plus an RBA Rate Adjustment (21.27% on Oahu), Public Benefits Fund surcharge, DSM/DRAC adjustments, and a Green Infrastructure Fee. These adjustments, not base rates, drive most month-to-month movement.
How does a business access its 15-minute interval data?▾
Register at eservice.hawaiianelectric.com, then open the My Energy Use portal (myenergyuse.hawaiianelectric.com). You can view 15-minute interval data and download it as Green Button XML or CSV, with a typical 24-hour lag. For automated access, third parties use Green Button Connect My Data (OAuth 2.0) or Nectar's API — see docs.nectarclimate.com; there is no public billing API from the utility.
Can a consultant or vendor get my data without my login?▾
Yes. You can add a view-only secondary user in eService, authorize a third-party app through Green Button Connect My Data (OAuth 2.0, scope-limited, revocable), or share data via Nectar (docs.nectarclimate.com). Hawaiian Electric does not provide shared credentials or a public EDI program for customer data.
Is there electricity supplier choice in Hawaii?▾
No. Hawaii is a fully regulated, vertically integrated market with no retail competition or community choice aggregation. Hawaiian Electric (and its Maui Electric and Hawaii Electric Light subsidiaries) is the sole provider in its territory, with all rates set by the Hawaii Public Utilities Commission.
