Reselling electricity: producer guide to monetising surplus in 2026
Feed-in tariff, spot price, direct PPA: how a solar or wind producer chooses where to sell surplus in 2026.
The 4 resale channels
1. Feed-in tariff / Complément de rémunération (EDF OA) — fixed price, volume cap, 15–20 yr exclusivity 2. EPEX SPOT — hourly variable price (-€50 to +€400/MWh), no volume guarantee 3. Direct corporate PPA — long term, negotiated price, traceable 4. Aggregator (Voltalia, Engie Green Markets) — pooling, 6–12% commission
2026 comparison for a 10 MW solar park
| Channel | Avg price | Annual revenue | Risk | Lock-in |
|---|---|---|---|---|
| Feed-in | €60/MWh | €660k | Low | 20 yrs |
| Spot | €47–82/MWh | €580k | High | None |
| Voltarione PPA | €65/MWh | €715k | Low | 5–15 yrs |
| Aggregator | €56/MWh | €615k | Mid | 1–3 yrs |
Why direct PPA wins
- Greening premium paid by the data center (~€3–8/MWh)
- Cash-flow security for bank refinancing
- Guarantees of Origin retained (separate resale possible)
- No intermediary commission on Voltarione

How much electricity does an AI data center really consume? A 2026 European benchmark (MW, €/MWh, PPA)
A frontier AI training cluster now draws 100–300 MW continuously, inference already accounts for 80–90% of AI compute, and the all-in energy cost of a 100 MW campus ranges from €38–55M/year in the Nordics to €118–149M/year in Dublin. A data-heavy 2026 European benchmark.
