PV export valorization regimes and BESS mechanisms (France).

What PV export is paid, when the battery can charge from the grid, and what additional revenues are possible, regime by regime.

The battery dispatch mode ("Optimized" = price arbitrage, grid charging allowed; or "Simple rule" = charge from PV surplus only) is an independent choice from the regime, except under S21, where the stored energy must come exclusively from the generating installation.

PV export valorization regimes

Regime	Export remuneration	Cap / limit	BESS charging from grid	Point of attention
No resale, individual self-consumption	None, surplus curtailed	Export = 0	As per chosen mode	—
S21 · EDF OA purchase obligation, ≤ 100 kWpNew	Fixed tariff of 1.1 c€/kWh excl. VAT, indexed by 2% per year (complete connection requests from 5 June 2026)	≤ 100 kWp, on a building, shed or carport; remunerated output capped at 1,600 kWh/kWp/year	No stored energy must come exclusively from the PV installation	20-year purchase contract. Requests filed before 5 June 2026 fall under the previous conditions.
CRE tenders · contract for difference (simplified tender 100-500 kWp, then rooftop and ground-mounted)New	Sale at market price + contract-for-difference premium referenced to a reference tariff	Simplified tender: eligible output capped at 1,600 full-load hours per year (2,200 with trackers)	To check in the tender specifications	Negative prices: no premium during those hours; beyond a 15-hour annual allowance, an annual payment equal to 50% of peak-power output at the reference tariff, subject to curtailment conditions (order of 16 April 2026). The producer stays exposed to the market; exact thresholds and conditions to be checked in the specifications of the relevant tender (source updated 3 July 2026).
Free market, PPA or aggregator	Price negotiated with the buyer or aggregator	No regulatory remuneration cap	As per chosen mode	—

Ancillary services and complementary mechanisms

Two distinct logics: external revenue (a third party pays you) or savings on the client's own bill (you pay less). Each mechanism activates independently of the others.

Mechanism	Revenue nature	Co-optimized hour by hour?	Key parameter	Limit / assumed simplification
FCR · primary reserve	External revenue	Yes	Capacity price (€/MW/h)	Capacity procured through a daily tender within the transmission operators' FCR cooperation (CRE deliberation No. 2025-174). Prequalification and commitment conditions to be checked with RTE.
Demand response	External revenue	No annual statistic	Sheddable capacity (MW), expected activations per year	Theoretical maximum potential: actual revenue depends on the number of activations actually called.
Peak shaving	Savings on own bill	Yes	Subscribed power (€/kW/year, TURPE 7) and any overruns	—
TURPE 7 · annual injection-withdrawal component (option, since 1 August 2026)New	Savings on own bill	Yes	Subscribed power per time slot (€/kW/year) and coefficients on withdrawn and injected energy depending on the zone; 12-month minimum commitment	Option reserved for standalone storage (hybrid installations excluded), connected at HTA or HTB, in a photovoltaic-injection or withdrawal zone listed by the CRE (deliberation No. 2025-227 of 1 October 2025). It replaces the standard withdrawal component. Excludes low voltage and non-interconnected zones.
Capacity mechanism · new RTE scheme (since 1 November 2026)New	External revenue	No annual statistic	Certified capacity (MW); 22 peak days (PP) per winter, time slots 7-10 am and 5-8 pm	RTE buys capacity through a centralized tender (Law No. 2025-127 of 14 February 2025, scheme authorized by the European Commission on 22 December 2025). Suppliers contribute in proportion to their customers' consumption during peak periods. Participation goes through a certification perimeter holder (TPC); a volume is reserved for decarbonized flexibility. Certification rules for a hybrid PV+BESS asset to be checked with RTE.
