Rate Schedules & Tariff Analysis
For MECO C&I customers, demand charges and the variable Energy Cost Recovery Clause dominate the bill. The non-fuel energy charge falls as you move up schedules (14.29 cents on G, 9.68 cents on J, 7.30 cents on P), but demand charges rise ($13/kW on J to $25/kW on P), so the optimal schedule depends on load factor. Because Hawaii's fuel-driven surcharges are large and volatile, all-in rates are typically the highest in the nation.
Maui Electric Company, Limited (MECO) Rate Schedule List
| Schedule | Applicability |
|---|---|
| Schedule J - General Service Demand | 25-200 kW; $13/kW demand, 9.6846 cents/kWh non-fuel. |
| Schedule P - Large Power Service | >=200 kW; $25/kW demand, 7.2992 cents/kWh non-fuel. |
| Schedule TOU-P | >=200 kW with time-of-use demand and energy pricing. |

Maui Electric Company, Limited (MECO) Data Access FAQ
How does a Maui C&I customer get 15-minute interval data?▾
Log into the My Energy Use Portal through eservice.hawaiianelectric.com and download up to 12-24 months of 15-minute interval data as Green Button XML or CSV. For automated access, use Green Button Connect My Data (OAuth 2.0) or Nectar's API (docs.nectarclimate.com).
Which rate schedule applies to my commercial facility?▾
Under 5,000 kWh/month and 25 kW you are on Schedule G; between 25 and 200 kW you are on Schedule J (General Service Demand); at or above 200 kW you move to Schedule P (Large Power) or the time-of-use Schedule TOU-P.
Can a third-party energy vendor pull our MECO data?▾
Yes. The cleanest path is Green Button Connect My Data, where your business authorizes the vendor's app via OAuth 2.0 for ongoing ESPI API access. Alternatively, add the vendor as a secondary user, or arrange a Data Sharing Authorization through your key account manager.
Why are our all-in rates so high compared to the mainland?▾
Hawaii imports most of its fuel, so the monthly Energy Cost Recovery Clause and Purchased Power Adjustment Clause add large variable charges on top of base rates, making MECO's all-in C&I rates the highest in the US. This is why demand management and on-site solar-plus-storage deliver outsized savings.
Does MECO support EDI for meter data?▾
Not as a primary offering. MECO directs data exchange to the Green Button ESPI API (Connect My Data) rather than traditional ANSI X12 EDI. Large trading partners can inquire with Business Development at (808) 543-7711, but Green Button is the recommended modern path.
