The state framework sets the default. Where KIUC (Kauai) pays something different, the utility tariff governs and is what the card above reports.
| Compensation mechanism | Hawaiian Electric (HECO, MECO, and HELCO): Smart Renewable Energy Export / Smart DER Export is the only export rider for new customers; it provides time-varying bill credits rather than retail-rate net metering. The Smart Renewable Energy Non-Export rider provides no export compensation. KIUC is separate: Schedule Q Modified pays for qualifying-facility energy delivered to KIUC at a monthly adjusted avoided-cost rate, and KIUC also lists a NEM Pilot tariff. |
|---|---|
| Export rate | Hawaiian Electric Smart Renewable Energy Export rates for 2024-2026, in $/kWh, by island and period: Oahu $0.135 daytime / $0.329 evening peak / $0.189 overnight; Hawaii Island $0.106 / $0.231 / $0.148; Maui $0.066 / $0.182 / $0.131; Lanai $0.267 / $0.408 / $0.259; Molokai $0.179 / $0.272 / $0.174. KIUC Schedule Q Modified is a monthly adjusted avoided-cost payment; the tariff does not set one fixed export rate. |
| Rate effective | Hawaiian Electric rates listed as 2024-2026; new SRE export rates are updated every three years. KIUC Schedule Q Modified uses an annual base rate plus a monthly fuel-price adjustment; the latest rate sheet located was effective December 1, 2022, so a current 2026 KIUC dollar rate was not verified. |
| Credit rollover | Hawaiian Electric SRE export credits roll forward during the 12-month period; BYOD Plus export credits do not expire. KIUC Schedule Q Modified is a cash/payment mechanism, not a stated banked-credit tariff. |
| Credit expiration | Hawaiian Electric unused SRE export kWh credits expire at the end of the 12-month period; BYOD Plus export credits are expressly exempt and do not expire. No KIUC Schedule Q Modified credit-expiration rule was identified because it pays for delivered energy. |
| Annual true-up | Hawaiian Electric export credits are trued up annually at the end of each customer's 12-month credit period; remaining credits then expire. The specific calendar true-up date is customer-specific rather than a statewide date. |
| Aggregate program cap | No aggregate capacity limit is stated for Hawaiian Electric Smart Renewable Energy Export. Legacy caps remain relevant to grandfathered programs, including Smart Export 38.5 MW for HECO, 16.5 MW for MECO, and CGS+ 104.5 MW for HECO; Battery Bonus caps were 40 MW Oahu and 15 MW Maui. |
| Program status | Smart Renewable Energy Export has no program capacity limit. The legacy Battery Bonus / Scheduled Dispatch Program is closed to new participants; its 40 MW Oahu cap was reached, and the Maui 15 MW program also closed. CGS, CGS+, and Smart Export are closed to new enrollment after March 31, 2024. |
| Grandfathering | Existing CGS, CGS+, and Smart Export customers are automatically transitioned to SRE Export seven years after their original contract date, with a six-month grace period described in Hawaiian Electric's transition flyer; they do not receive the new-customer seven-year rate lock after transition. Existing NEM and NEM Plus customers are not required to transition. New SRE customers receive a seven-year export-rate lock, then rates update every three years. |
| Regulator | Hawaii Public Utilities Commission (HPUC) |
| Governing rule | Hawaiian Electric Rule 32, Smart Renewable Energy Program, under HPUC Decision and Order No. 40418 as modified by Order No. 40670; interconnection is governed by Rule 14H. KIUC uses Tariff No. 1 Schedule Q Modified and Tariff No. 2 Distributed Generation Interconnection Policies and Procedures. |
| Pending change | HPUC Docket No. 2026-0084 is an open proceeding to design and implement a Virtual Power Plant grid-services program for Hawaiian Electric service territories, with remote dispatch, performance-based compensation, and expanded access under consideration. It may add a battery/DER capacity-payment pathway, but no final VPP compensation rate was verified as of September 16, 2026. |
