Certification
RECs are known under functionally equivalent names such as Green Tags or Tradable Renewable Certificates (TRCs), depending on the market. The U.S. currently does not have a national registry of RECs issued. The Center for Resource Solutions administers a voluntary program which attempts to ensure RECs are properly accounted for and no double counting takes place. Under the Green-e Energy program, participants are required to submit to an annual Verification Process Audit of all eligible transactions to ensure the RECs meet the requirements for certification. The certification process requires 3rd party verification to be performed by an independent certified public account or a certified internal auditor. The CRS maintains a list of auditors who meet the criteria to be listed on the program website. Increasingly RECs are being assigned unique ID numbers and tracked through regional tracking systems such as WREGIS, NEPOOL, GATS, ERCOT, and M-RETS.
