Reselling electricity: producer guide to monetising 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
