Exploring commercial dynamics and opportunities with battery storage in France, which is poised to become one of Europe’s top markets.

How to secure and diversify BESS revenues by allocating available capacity strategically across wholesale, FCR, and aFRR.

Transparency drives market maturity, but existing BESS revenue claims lack verifiability. The new portfolio performance metric addresses both.

How does data point quality impact BESS optimization? This article explains why an advanced trading strategy depends on solid data input.

An overview of the different BESS revenue strategies that help secure financing (fully merchant, floor pricing, tolling), including examples.
Cross-market battery optimization strategically distributes BESS capacity across all relevant power markets to maximize revenues and support grid stability. Currently, storage systems can be marketed for ancillary services in FCR (Frequency Containment Reserve), aFRR (automatic Frequency Restoration Reserve) energy, and aFRR capacity, all of which are regulated by the TSO (Transmission System Operator).
While mFRR (manual Frequency Restoration Reserve) is currently not relevant for cross-market optimization, it is essential to additionally branch out into wholesales, also known as the spot market, which covers day-ahead, intraday, and continuous intraday auctions. These are not regulated by the TSO and do not require pre-qualifications or security of supply. Instead, they can be accessed directly through the power exchange. It is commonly observed in the European market that batteries are placed in ancillary services only (mostly FCR), which puts asset owners at risk and makes them financially vulnerable.
Through cross-market battery optimization, you benefit from revenue stacking, revenue maximization, commercial diversification, risk mitigation, and arbitrage opportunities all at the same time.
Clean Horizon’s storage index shows high revenue potential for storage in 2025, noticeably for July (€298k/MW/Year for 1-hour assets), which was a notoriously challenging month for BESS in Germany by comparison. Select France on this page to check the index.
Given current market signals and the lack of saturation, 2026 is shaping up to be a promising year for BESS in France.
