Automate REC issuance and retirement tracking against M-RETS and WREGIS registries

Steps

1. Register your organization and generators with the target registry: M-RETS (app.mrets.org) for Midwest and voluntary national markets, WREGIS (wecc.org/WREGIS) for the Western Interconnection; obtain API credentials from each registry's account settings.
2. For M-RETS, review the API documentation at mrets.org/api/ and use the provided API key to authenticate requests; the M-RETS API provides endpoints for certificate inventory, transactions, retirements, and generator data.
3. Automate issuance for registered generators: submit meter data uploads (generation MWh by month) to the registry's generation upload interface — M-RETS accepts CSV uploads or API submissions; the registry issues RECs (one per MWh) with unique serial numbers upon verification.
4. Track certificate inventory: query the active certificates endpoint periodically to retrieve certificates by serial number range, vintage, fuel type, and eligibility flags; store the full certificate record including all eligibility attributes needed for compliance claims.
5. Automate retirements: when a customer's EAC matching requires retirement, submit a retirement transaction via the API specifying the certificate serial numbers, retirement reason (voluntary/compliance), and the beneficiary account; record the registry's retirement confirmation and certificate number.
6. For WREGIS-to-M-RETS transfers (imports), use M-RETS's WREGIS Reserve Account import workflow; note that WREGIS certificates must first be deposited to a WREGIS Reserve account before M-RETS can import them — implement this two-step process in your automation.
