Customer Grid-Supply (CGS) enables residential and commercial customers to connect private rooftop solar or other renewable systems (up to 100 kW total output capacity) to the electric grid. CGS provides eligible customers with credits on their electric bills for excess electricity sent to the grid or energy delivered by the Company to the customer-generator, whichever is less at a fixed rate approved by the Hawaii Public Utilities Commission through October 20, 2022 (see table below). These credits can help customers offset all or part of their electrical usage and lower their bills. These customers are billed the retail rate for all electricity they use that they receive from the utility.
*Export credits may only be used during the month they are generated. Excess monthly credits expire with the utility cost reductions benefiting all customers.
Program Capacity Remaining
The CGS program has a capacity limit that varies by utility. The available capacity is shown here and program will remain open until installed capacity is reached. Applications received will be processed if and when capacity is available due to other applications being withdrawn from the program.
|Island||Original Capacity MWac||Added Capacity*||Total Capacity MWac**|
|Hawaii Electric Light||5.00||4.91||9.91|
* Capacity available from Net Energy Metering applications that were cancelled or withdrawn
** As of Nov. 7, 2017, the CGS program reached the total capacity allotted. Two new programs have been approved by the PUC on Oct. 20, 2017.
*** Includes Maui, Molokai and Lanai
The safe, reliable operation of the grid is important to everyone. The combination of utility system upgrades and leading-edge, customer-facing technology is providing new opportunities to connect more private rooftop solar or other renewable systems in less time with greater efficiency. All new systems in Hawaii are now required to use advanced inverters that help maintain a stable and reliable grid.

The CGS program is open, but new applications will be held in queue on a first-come, first-served basis until space in the program becomes available. To apply for this program, you’ll need to download and submit the Distributed Energy Resources Application Submittal Form and Agreement (CGS).
