Regulatory, Financial, and Sustainability Considerations
Regulatory, financial, and sustainability considerations
Energy procurement sits inside regulation and accounting. Regulated tariffs, unbundled transmission and distribution charges, capacity accreditation, renewable portfolio standards, carbon pricing, and market rules determine what can be bought and at what delivered cost. Renewable procurement includes physical PPAs, virtual PPAs, green tariffs, and energy attribute certificates. A physical PPA delivers electricity and attributes; a VPPA is a financial contract for differences and does not supply power to the site. RECs support renewable claims but are not the same as carbon offsets. For reporting, distinguish scope 1 direct emissions, scope 2 purchased energy, and scope 3 value-chain emissions, and know market-based versus location-based scope 2 methods. Accounting and treasury teams must classify derivatives, leases, and credit support; collateral and margining affect liquidity even when the hedge is economically sound.
Worked example: a VPPA strikes $40/MWh for 50,000 MWh. If the reference price settles at $50/MWh, the buyer pays $10/MWh × 50,000 = $500,000 to the project, while still buying physical power at the market price. If the reference is $30/MWh, the project pays the buyer $500,000. The buyer gains RECs and price certainty but retains volume and basis risk. Traps include counting RECs as emissions reductions, ignoring regulatory approval or delivery point, and assuming a VPPA reduces the physical power bill. Rule of thumb: verify the regulatory treatment, delivery point, attribute ownership, and accounting classification before signing; sustainability claims must be backed by the right instrument.
