Clean Energy

Clean Energy Generation

Hawaiian Electric provides many ways for you to produce power for your own use or to sell to the utility. The Hawaii Public Utilities Commission (PUC) requires when you generate renewable or nonrenewable electricity and remain connected to the utility’s grid that you have an interconnection agreement and, if applicable, a power contract with Hawaiian Electric. This includes systems such as solar (photovoltaic), wind, hydro, fuel-cell or synthetic natural gas. This site will help you understand the different ways that you can connect, whether you export power to the grid or simply reduce the amount of power you purchase.

February 2014:

New Net Energy Metering agreement forms - On February 3, 2014, the PUC issued an order revising the NEM Tariff to clarify that a fully executed NEM Agreement is required prior to interconnection and operation of a generating facility in parallel with our electric system.  Please use the new Appendix I and Appendix II forms immediately.  

Energy storage systems - In addition, per the PUC’s order, any generating facilities that use an energy storage device must have the Company perform an interconnection review before interconnecting.

January 2014:

PV systems with battery backup must also get an initial review by the utility to ensure interconnection is done properly.  As a reminder, please read about our steps to help PV customers interconnect.


Producing Your Own Power

Net Energy Metering

Designed to encourage greater use of solar (photovoltaic), wind, biomass, or hydroelectric power for electrical generation by residential and commercial customers. NEM allows you to offset all or part of your electricity purchases from the utility by energy produced by your eligible renewable generation system and export any excess electricity to the utility grid at the retail rate.
Rule 18 | Questions | Forms
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.

Selling Power to Hawaiian Electric

Competitive Bidding

Adopted by the PUC as a mechanism for acquiring or building new energy generation in Hawaii. The process is initiated by Hawaiian Electric with the issuance of a Request for Proposals (RFP). All projects greater than 5MW on Oahu are subject to the PUC's Framework for Competitive Bidding. Please see Hawaiian Electric's Competitive Bidding page for more information.

Feed-in Tariff (FIT)

FIT is designed to encourage renewable energy projects through standardized pricing and contract terms. Project sizes up to and including 5 MW on Oahu are eligible for FIT. Prices are based on type of technology and tiered by the size of your system. Please see Hawaiian Electric's Feed-In Tariff page for more information.

Tariff Tier 3 | Appendix I Tier 3
Appendix II Tier 3 | Apply

Schedule Q

Schedule Q describes the standard rates, terms and conditions that apply when the utility purchases as-available energy from customers with small cogeneration and/or small power production facilities of 100 kW or less in capacity.

Geothermal RFP

Geothermal power, already a proven source of firm renewable power, can potentially play an even larger role in Hawaii’s clean energy future. Hawaii Electric Light Company seeks to expand geothermal energy on Hawaii Island. Prospective bidders and interested parties are encouraged to participate.
