Supplemental FAQ

Metering Requirements

The IPA requires a minimum standard of meter accuracy for systems participating in the Supplemental Procurement.

Under 10kW

May use inverter readings if the inverter is accurate to +/- 5%


Need to use a revenue grade meter which is defined as accurate to +/-2% that meets ANSI C.12 standards. The meter may be refurbished.

Over 25kW

Need to use a new revenue grade meter which is defined as accurate to +/-2% that meets ANSI C.12 standards. For more information please visit: IPA Meter Requirements

How to register a system

System Owners

Please follow this link and fill out the form on our website. We will use your information to generate a contract for you. As soon as we have a signed contract back from you we will begin registering your system with a tracking system and the IPA.


Installers may use this link on our website to register systems on behalf of system owners. Alternatively they may use a shared spreadsheet that has been generated and sent over. If you would like CSG to send over a spreadsheet to register your systems please contact us and we will have one right over.

How is pricing determined?

The prices in the Supplemental Procurement are set during a blind bidding process. The IPA has set “benchmark” or price ceilings for each size category. Any bid above these prices will be automatically rejected. After these bids are rejected they select bids from lowest price to highest price until they have hit their target for quantity of RECS or run out of money.

CSG has participated in many SREC bidding processes and has developed a strategy for pricing bids into these procurements to maximize revenues to system owners, while minimizing the risk of not being selected. Because of the competitive nature of this bid CSG can only discuss pricing availability and strategy with committed installer partners. Please see our installer page for more information on partnering with us.

For individual system owners that would like to bid their systems in with us please fill out this form. From there we will contact you directly about your system’s pricing options.

What are the bonding requirement to bid?

The IPA Requires an $8 per REC bond for all Identified systems and a $16 dollar per REC bond for all speculative systems. There may be cases where CSG covers part or all of this bond for systems. Please contact us for more information.

When can I expect my first payment?

The timing of the first payment is dependent on the size of the system and the date that the system gets registered on a tracking system. Generally speaking this is 6-9 months after systems are identified to CSG and energized, but this period is longer for smaller systems or systems with delays in the registration process.
