Producing Clean Energy
Hawaii Electric Light 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 Hawaii Electric Light. 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.
Producing Your Own Power
Customer Self-Supply (CSS) and Customer Grid-Supply (CGS) 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.

On September 26, 2017, the Hawaiian Electric Companies issued Source Requirements Document version 1.1 ("SRD v1.1") to allow manufacturers to be able to comply with formal certification to UL 1741 Supplement SA by March 10, 2018. Manufacturers may formally certify or utilize self-certification to qualify their grid support utility-interactive inverters by following the updated Grid Supportive Utility-Interactive Inverter Certification Requirements (click on hyperlink) which contains links to SRD v1.1, modified self-certification forms, and updated Grid Support Utility Interactive Worksheets. If you have any questions, please send email to DER-SelfCertification@hawaiianelectric.com.
Selling Power to Hawaii Electric Light
Adopted by the PUC as a mechanism for acquiring or building new energy generation in Hawaii, the competitive bidding process is initiated by Hawaii Electric Light with the issuance of a Request for Proposals (RFP).

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.
