The UK Renewables Obligation made non-compliant suppliers fund the compliant ones

Suppliers had to present tradable ROCs or pay a buy-out price, and the buy-out pot was recycled to the suppliers who met their obligation.

the move

Britain wanted a rising share of green electricity without an open-ended feed-in subsidy. The Renewables Obligation put the burden on licensed suppliers: each had to show Ofgem that a specified percentage of the electricity it sold came from eligible renewable sources, rising from 3% in the first year to 10.4% by 2010-11.

To comply, a supplier could present ROCs — tradable certificates Ofgem issued to eligible renewable generators — or pay a buy-out price of £30/MWh in the first year, indexed to the RPI thereafter.

The clever part is what happens next. Ofgem collects the buy-out payments and returns all of them to suppliers in proportion to the number of ROCs each one presented. So the money that laggards pay is handed directly to the suppliers who actually met the obligation, making non-compliance a source of funding for compliance.

why it works

  • The buy-out-and-recycle creates a powerful, self-financing incentive to comply: failing suppliers pay, and compliant suppliers share the pot.
  • The tradeable ROC gives each renewable megawatt-hour a market value that shrinks as more green power enters.
  • The obligation and the resulting ROC market set a transparent price for greenness without the government picking a per-technology tariff or committing to a fixed outlay.
  • The ordering — obligation, then buy-out, then recycling — punishes free-riding while multiplying the reward for those who do the work.

what transfers

If you impose an obligation, attach a penalty and recycle its proceeds to the people who hit the target; the fine becomes the subsidy and the scheme prices itself without drawing on the budget.

what came after

The Renewables Obligation drove a large build-out of UK renewable capacity and underpinned the early offshore-wind industry. It later gave way to Contracts for Difference auctions, which set strike prices competitively and were seen as cheaper, while the buy-out-and-recycle logic remained a durable template for a market-based green obligation.
