A delivery obligation is a contractual or regulatory commitment to provide a specified quantity and type of energy attribute certificates by a specified deadline. Failing to meet a delivery obligation can trigger financial penalties, contract breaches, and reputational damage.
Delivery obligations arise from several sources: outbound sales contracts (where the seller has committed to deliver certain certificates to a buyer), compliance obligations (where a regulator requires certain volumes to be cancelled to meet a renewable energy mandate), supplier obligations such as the UK Fuel Mix Disclosure, and internal commitments such as a corporate parent's RE100 target.
A delivery obligation specifies the quantity (in MWh), the certificate type (GoO, REC, I-REC, etc.), often the technology mix (wind-only, solar-only, or mixed), the vintage requirements, the geographic origin, and the deadline by which delivery must be completed. Two obligations for "1,000 MWh of European renewable energy" can have completely different fulfillment criteria depending on the contractual detail behind them.
Most utilities track delivery obligations across multiple spreadsheets, one per counterparty contract or compliance scheme. Each sheet typically tracks expected versus delivered volume, with manual updates as trades happen. This fragmented approach is a primary source of missed obligations, particularly when a single trade can satisfy parts of multiple obligations and when obligations span multiple registries.
Missed obligations have both direct and indirect consequences. Direct consequences include financial penalties built into contracts, regulatory fines for compliance failures, and the cost of sourcing replacement certificates at short notice in a high-priced market. Indirect consequences include damage to counterparty relationships, scrutiny from auditors and verification bodies, and reputational risk with end customers relying on the supplier's renewable claims.
