Producing Clean Energy

Standard Interconnection Agreement

A SIA is for renewable and non-renewable systems. This agreement allows you to reduce the amount of energy you require from the utility by energy produced from your system. Any surplus exported to the grid will not be "stored" or credited on your bill.

To view the complete tariff governing Standard Interconnection, please see: Rule 14H

Distributed Energy Resource Inspection

Prior to operating your system continuously, an inspection is required to verify compliance with Standard Interconnection Agreement Rule 14H.

Scheduling of the test requires a two (2) week lead time.

The inspection will verify the following:

  • The installation, including equipment ratings, matches the issued Single Line Diagram.
  • The Inverter(s) meet UL-1741 standard nameplate.
  • The manual disconnect switch is properly labeled.
  • No backfeed - The customer simulates a "loss of utility" power to the system by opening the disconnect switch or breaker. The customer must have a qualified person to measure, with a voltmeter, that there is no backfeed at the open disconnect switch.*

* For liability purposes Hawaiian Electric Company, Inc. will not operate your equipment and so we ask that you provide a qualified person/electrician to be available to conduct the test.
