New Solar Incentives in Illinois, Net Metering Ends for Duke Energy South Carolina

| Reading time 2 minutes

The roller coaster for solar in the U.S. (call it a Solar Coaster?) keeps rolling this summer.  The state of Illinois has finalized the credit values for its Adjustable Block Program, which provides solar owners with an upfront payment for 15 years of estimated solar production.  Meanwhile, in South Carolina the state legislature failed to increase the net metering cap and Duke Energy has met its 2% limit. Starting on August 1, 2018 full net metering closes for Duke Energy SC customers and will be replaced by the Purchased Power Rider. First the good news for solar developers:

Adjustable Block Program in Illinois

In June the Illinois Power Agency published the final values for the Adjustable Block Program(ABP), and Genability has published the ABP incentives for your use. For those who are unfamiliar, the ABP offers a per kWh credit for the first 15 years of estimated solar production to be paid upon interconnection for systems under 10 kW.  The amount of the credit varies according to utility and system size and is in addition to the customer’s monthly net metering credits.

  Commonwealth Edison Ameren - Illinois Mid American - Illinois
Under 10 kW 7.297¢/kWh 8.51¢/kWh 8.51¢/kWh
10 - 25 kW 7.323¢/kWh 7.87¢/kWh 7.87¢/kWh

The Illinois Power Agency has selected a program administrator and is expected to start accepting applications for the program this fall. We have made these incentives available via our API to allow our customers to include the ABP in their savings calculations ahead of the program’s official opening.

End of Net Metering for Duke Energy - South Carolina

This spring it seemed that the South Carolina legislature was prepared to increase the Net Metering cap in South Carolina from 2% to 4%, but the bill that emerged from committee did not up the cap.  On August 1st, Duke Energy will close Net Metering and move solar customers onto the Purchased Power Rider that compensates solar customers at a lower rate for power provided to the grid.  Due to the earlier merger of Duke Energy and Progress Energy, Duke Energy currently maintains two sets of rates within South Carolina (and North Carolina), thus the two columns in the table below:

  Duke Energy Duke Energy (formerly Progress)
Fixed Charge $11.07 $8.05
Summer On-Peak Credit $0.1035 $0.0963
Summer Off-Peak Credit $0.0334 $0.0346
Winter On-Peak Credit $0.0661 $0.0611

For all of Duke Energy, On-Peak is defined as 1 PM to 9 PM in the Summer and 6 AM to 1 PM in the Winter, aligning reasonably well with the peak hours of solar production. Genability has created new Purchased Power Rider versions of all Duke Energy SC tariffs and will make them the default post-solar tariff in our Switch API on August 1.
