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.
