REC-13: Is it permissible to provide RECs registered under a tracking system other than those named in the Supplier Master Agreement (MRETS, PJM GATS, or NARR)?

No, these are the only acceptable tracking systems. A Bidder must have an existing account with PJM EIS GATS and/or MRETS and/or NARR, or the Bidder must certify to having no impediment to obtaining an account with one of these tracking systems for the transfer or retirement of RECs under the applicable supplier contract.
