As of March 2026, the Hawaiian Electric (HECO) interconnection landscape has fully shifted to the Smart DER (Distributed Energy Resources) ecosystem. For Oahu homeowners, choosing between the Export and Non-Export pathways is no longer just about “saving money”—it is a technical decision based on your home’s hardware, your neighborhood’s grid saturation, and your battery capacity.

This guide breaks down the technical specifications of the Smart DER Tariff to help you determine which interconnection pathway fits your system architecture.

The Smart DER Framework: Export vs. Non-Export

In 2024, HECO consolidated several legacy programs (CGS, CGS+, Smart Export) into the unified Smart DER program. By 2026, this has become the standard for all new interconnections on Oahu.

1. Smart DER Export Pathway

This pathway is designed for systems with battery storage that can “load shift.” You use your solar energy during the day to charge your batteries and export excess power to the grid during specific windows for bill credits.

  • Technical Requirement: Requires an Advanced Meter and an Advanced Inverter compliant with HECO Rule 14H.

  • Oahu Export Rates (2024-2026):

    • Daytime (9am – 5pm): 13.5¢ / kWh

    • Evening Peak (5pm – 9pm): 32.9¢ / kWh

    • Overnight (9pm – 9am): 18.9¢ / kWh

  • Best For: Homeowners with high-capacity batteries (e.g., Tesla Powerwall 3) who want to “sell back” power during the expensive evening peak.

2. Smart DER Non-Export Pathway

This is a “self-supply” model. Your system is technically configured to prevent any energy from flowing back into the HECO grid.

  • Technical Advantage: Expedited Review. Because you aren’t sending power back, HECO typically grants technical approval much faster, even in “saturated” neighborhoods where the grid is at capacity.

  • Zero Export Control: Requires a certified power control system (PCS) or “Zero-Export” setting on your inverter to ensure no backfeed occurs.

  • Best For: Residents in grid-saturated areas of Oahu (like parts of Ewa or Kapolei) or those who simply want the fastest possible permit-to-install timeline.

Technical Comparison Table

Feature Smart DER Export Smart DER Non-Export
Grid Impact Active Export Zero Backfeed
Interconnection Speed Standard (Rule 14H) Expedited
Battery Required? Highly Recommended Required for night use
Compensation Time-of-Use Credits $0 (Self-Consumption Only)
Meter Type Advanced Meter (Bi-directional) Advanced Meter

The BYOD+ Integration (Bring Your Own Device)

For technical searchers, the Bring Your Own Device Plus (BYOD+) program is the “Level 2” of interconnection. It sits on top of your Smart DER agreement and allows HECO to “call” upon your battery during grid emergencies.

  • Technical Trigger: Your battery must be capable of autonomous response to grid frequency changes.

  • The Benefit: In exchange for this technical “Grid Service,” you receive an upfront cash incentive and additional monthly bill credits.

Technical Hurdles: Why Rule 14H Matters

Every solar application on Oahu must pass a Rule 14H technical review. If your local transformer is already “full” from your neighbors’ solar systems, a standard Export application may be denied or require an expensive Interconnection Requirements Study (IRS).

The Hi-Power Solar Technical Advantage: Our engineers specialize in “Non-Export” configurations that bypass these grid saturation hurdles. By utilizing advanced software in modern inverters, we can often get your system approved in weeks rather than months by guaranteeing zero-export to the HECO grid.
