Clean Energy

Renewables and Customer 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.


November 2015:

Advanced Inverter Interconnection Requirements for Inverter-Based Distributed Energy Resources

October 2015:

Customer Grid-Supply and Customer Self-Supply applications now available.

October 2015:

Public Utilities Commission (PUC) approves new rooftop solar programs. The PUC also directed that these new options will replace the NEM program. Customers with a current NEM agreement and those with valid pending applications hand delivered or postmarked on or before Oct. 13, 2015 will continue under the NEM program.

October 2015:

A Distributed Generation (DG) Interconnection Project Validation Packet will need to be submitted for all programs.

Producing Your Own Power

Customer Grid Supply (CGS) and Customer Self Supply (CSS) Programs

These programs provide customers with options to install both traditional rooftop photovoltaic systems and systems equipped with new emerging technologies, such as battery storage systems.
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.

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.
