💡 Accountant's Note

RECs (also called SRECs for solar, or TRECs) are certificates representing the environmental attributes of one MWh of renewable electricity generation. They are created by RECS registries (PJM-GATS, NEPOOL-GIS, WREGIS, ERCOT RECS) when renewable generation is verified. RECs can be sold separately from the underlying electricity — allowing utilities to count purchased RECs toward their Renewable Portfolio Standard (RPS) obligations. The accounting: generated RECs are intangible assets valued at the lower of cost or net realizable value. Revenue is recognized when RECs are sold to buyers who need them for RPS compliance.

Practitioner & Systems Framework

💻 ERP Architecture

REC tracking requires integration between the generation metering system and the state REC registry. RECs are issued monthly based on verified generation data. Maintain a REC inventory sub-ledger showing: RECs generated, RECs sold (with proceeds), RECs retired for own RPS compliance, and RECs expired. RECs typically have a limited validity period (2–5 years from generation).

⚠️ Audit Flags

Auditors verify REC inventory against registry account statements. The valuation of RECs (lower of cost or NRV) requires market price assessment — REC markets can be illiquid and prices can vary dramatically by state and technology type. RECs sold below their carrying cost require a write-down.

📄 Required Documentation

State REC registry account statements, generation data supporting REC issuance, REC purchase/sale contracts, market price assessment for year-end valuation, REC inventory roll-forward (generated + purchased - sold - retired - expired).
