How Romania's CfD actually works

The Contract for Difference converts a merchant-exposed asset into a bankable one. Here is the mechanism, the track record, and why it is durable.

How Romania's CfD actually works

The Contract for Difference is the single most important instrument standing between a Romanian renewable project and a bank's credit committee. It converts a merchant-exposed asset into a contracted one. Two auction rounds and a third tender in, it now has a track record worth reading closely — and the headline lesson is that strike prices are falling fast.

The mechanism, in one paragraph

Under a two-way CfD, a generator's revenue is stabilised at a contracted strike price for fifteen years, settled against a market reference. When the market price falls below the strike, the State pays the difference; when it rises above, the generator pays it back. The practical consequence is the one that matters to a lender: the bank underwrites a strike price, not a price forecast. The revenue line stops being a merchant assumption and becomes a contracted cash flow.

A contract, not a promise

The scheme was approved by the European Commission on 6 March 2024 — a €3 billion envelope financed through the Modernisation Fund and the National Recovery and Resilience Plan, with fifteen-year contract terms. Because the support lives under an EU State Aid approval, its terms cannot be cut by national decree alone: any material change requires Romania to re-notify Brussels. That is the difference between policy support that is a promise and policy support that is a contract — and it is why a CfD strike is bankable in a way that a feed-in tariff set by ministerial mood is not.

The track record: three rounds, falling strikes

The first three procurement rounds tell a clear story. Solar cleared aggressively and got cheaper; wind cleared higher and repeatedly under-filled its quota.

Round Result date Solar awarded Solar avg strike Wind awarded Wind avg strike
Round 1 Dec 2024 432 MW €51/MWh 1,096 MW €65/MWh
Round 2 Aug 2025 ~1,488 MW €40.5/MWh ~1,260 MW €73.8/MWh
Round 3 Nov 2025 — (wind-only) ~316 MW €60–75/MWh

Round 1 was capped at €91/MWh (solar) and €93/MWh (wind). Round 2 offered 3,472 MW (1,472 solar / 2,000 wind) but a third of the wind quota went unallocated. Round 3 offered 290 MW of onshore wind at an €80/MWh cap.

What the numbers tell an investor

The solar story is the one to internalise. The average solar strike fell from €51/MWh in December 2024 to €40.5/MWh by August 2025 — a ~21% compression in eight months, driven by competition and falling capex. There are two ways to read that, and a serious investor holds both at once.

Solar · Round 1€51.0
Solar · Round 2€40.5
Wind · Round 1€65.0
Wind · Round 2€73.8
Average awarded strike prices, €/MWh. Solar compressed round-on-round; wind rose and under-subscribed.

Reading one: Romanian solar is genuinely low-cost, and bidders can clear at €40/MWh and still finance. Reading two — the more important one: as strikes converge toward the cost floor, the value of a CfD shifts. It is no longer primarily a fat spread over cost; it is contracted certainty. The instrument's worth is the elimination of fifteen years of merchant price risk, not a guaranteed margin. Investors who underwrote Round 1 strikes captured both; investors entering now are buying the certainty, and must be sharper on capex and execution to protect equity returns.

Wind tells the opposite story. Round 2 left roughly a third of its wind quota unallocated, and Round 3 was a small wind-only tender that cleared at €60–75/MWh. Wind economics in Romania are tighter and siting is harder — a signal that the near-term bankable pipeline is solar-led, with wind selective.

The window is narrowing

The CfD is the difference between underwriting a price forecast and underwriting a contract. But the most attractive strikes have already been awarded — each round has cleared lower than the last.

For an investor entering Romanian PV today, the CfD remains the cleanest route to a bankable revenue line: EUR-denominated, fifteen years, protected by an EU State Aid contract rather than a national promise. The strategic implication is timing. Strikes are compressing, and a ready-to-build project that can enter the next round — rather than wait two more — locks a higher contracted price against a falling curve. In a maturing auction market, the premium is on being ready, not on being early to the idea.
