Hawaiian Electric provides many different programs that allow you to produce power for your own use or to sell back to the utility. Whether you export power back to the grid or simply reduce the amount of power purchased from us, the Public Utilities Commission (PUC) requires that you have an interconnection agreement and, if applicable, a power contract with Hawaiian Electric Company when you generate renewable or nonrenewable electricity and remain connected “in parallel” with the utility’s grid. 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.
Read about steps to help customers caught in the transition to the September change in procedures to interconnect a rooftop solar system. (Note: December 31, 2013 deadline)
Per Rule 14H inverter settings need to be set at 57 Hz and 300 seconds as of December 23, 2011 for all FIT, NEM, and SIA projects interconnecting into the Hawaiian Electric distribution system. For more details refer to Rule 14.
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
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. Rule 14 | Email Us | Forms | Requirements
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.
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 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.
