The project
The Performance Storage Operation
Performance 8 Energy is developing 2 stand-alone BESS projects in France, totaling a rated power of 170 MWn and a storage capacity of 935 MWh . This represents a full discharge duration of 5.5 hours .
| Project No. | Department | Status | Rated Capacity (MWn) | Charge/Discharge Duration (hours) | Storage Capacity (MWh) |
|---|---|---|---|---|---|
| F.BESS.AS99 | 86 | Secured land, Town hall agreement obtained, preliminary connection feasibility obtained | 60 | 5.5 | 330 |
| F.BESS.BO19 | 21 | Secured land, Town hall agreement obtained, preliminary connection feasibility obtained | 110 | 5.5 | 605 |
| TOTALS | 170 | 5.5 | 935 |
The first project, F.BESS.AS99, is located in the Vienne department near an RTE source substation.
The second project, F.BESS.BO19, is located in the Côte d’Or department, also near an RTE source substation.
Battery Technology at the Service of the Electrical System
💡 BESS? Stand-alone Battery? What’s that?
-
BESS stands for Battery Energy Storage System (or in French, Battery Storage System) is a system that allows storing electricity via rechargeable batteries and integrating an intelligent management solution.
-
Stand-alone or autonomous battery, the latter is not connected to an electricity production plant, it is placed in a strategic location for the electrical network.
💡 Why develop electricity storage batteries in France?
The operating principle of BESS allows optimizing the balance between supply and demand for electricity on the network. The batteries charge during periods of low demand, when electricity is more abundant and less expensive, and then discharge during periods of high demand, thus helping to smooth out consumption peaks. They strengthen the stability of the electrical network by offering system services, such as frequency regulation, when available.
They offer several advantages:
- Better integration of renewable energies,
- Solution to balance supply and demand,
- Element of security and stability for the electrical network,
- Reduction of dependence on fossil fuels.
The French Battery Market
The French electrical network is undergoing significant transformation, with the rise of variable renewable energies (solar, wind) and the reduction of the share of conventional dispatchable means (thermal, in particular).
The network must maintain the balance between supply and demand and the frequency at 50 Hz, in a more volatile context.
Battery storage (BESS) meets this growing need, providing immediate (a few milliseconds) and bidirectional (charge/discharge) flexibility.
The revenues of a BESS are divided into three complementary pillars:
1. Network Balancing by RTE: System Service
The RTE network responds to balancing needs by activating energy reserves sequentially:
- FCR: Primary reserve (automatic/immediate), including BESS.
- aFRR: Secondary reserve (automatic/a few minutes), including BESS.
- mFRR: Tertiary reserve (activated manually by RTE, allowing action on the network in the medium term when the imbalance cannot be resolved immediately).
Producers are remunerated by RTE for their reserve activities as part of network balancing.
2. Capacity Market: A Stable and Predictable Base
The capacity mechanism aims to ensure the security of electricity supply in France during winter peak periods. It is based on the obligation to cover peak consumption by obligated parties and on the certification and valuation of production and curtailment capacities.
- Certification of firm power
- Annual remuneration €/MW certified
- Long-term structuring pillar
3. Spot Trading Market: Day-Ahead & Intraday (15-minute interval)
Another source of revenue for BESS installations is the buying and selling of electricity on the SPOT market.
Electricity is a product sold on the wholesale market . BESS operators can therefore follow the market price to buy electricity at its lowest price (period of low demand and high production) to resell it later when the price is higher (period of high demand and lower production).
Since October 1, 2025, the “spot” electricity market has switched from hourly to 15-minute intervals, meaning the price of electricity is now set for each quarter-hour rather than for each hour. This change has significant impacts on price volatility, and this granularity benefits BESS assets, which could increase their revenue by 10 to 25%.
Variation of electricity prices on the Epex Spot and Nord Pool hubs in France on 18/02/26 ( RTE )
This multi-market strategy strengthens the economic resilience of assets by diversifying revenues, allowing dynamic optimization between the different market mechanisms and limiting exposure to a single performance lever.

PERFORMANCE 8 ENERGY: Structuring Renewable Energies Together
PERFORMANCE 8 ENERGY is a French company based in Marseille since June 2024, specializing in the structuring and development of energy flexibility projects, including battery energy storage systems (BESS) connected to the RTE grid and photovoltaic power plants.
The company structures strategic projects that meet the growing needs for stability of the French electrical network, with diversified and resilient revenue models.
PERFORMANCE 8 ENERGY intervenes "from scratch," from project origination to the Ready-to-Build status.
The projects developed aim to diversify revenue sources (electricity market arbitrage, reserve mechanisms, capacity mechanisms), contributing to the visibility of cash flows and the long-term economic robustness of the assets.
Focusing most of its activity on the French territory, Performance 8 Energy also deploys in Italy thanks to a local partner.
A Multidisciplinary Team
PERFORMANCE 8 ENERGY was born within the energy division of a startup studio, inheriting an entrepreneurial culture marked by its speed of adaptation and execution in the face of the constant evolution of the energy market.
The company is led by a multidisciplinary founding team, composed of:
- A lawyer, president of the company, specialist in project structuring;
- An economist, expert in financial modeling, energy market analysis, and economic positioning strategy of assets;
- A psychologist, responsible for corporate communication and institutional positioning of the company.
This complementarity allows PERFORMANCE 8 ENERGY to anticipate regulatory developments and network orientations, to quickly structure complex energy projects, and to adjust their positioning in real-time in response to market dynamics.
Long-Term Ambitions
PERFORMANCE 8 ENERGY first aims to materialize its first storage and solar energy projects, strengthening its partnerships and operational footprint. Then, the company plans to scale up industrially, with a platform capable of managing multiple projects simultaneously, while securing their execution. Finally, it aspires to become a key player in long-duration storage in Europe, optimizing network flexibility and energy markets. An ambitious trajectory to shape the future of energy.
Our analysis
Risk overview
Refinancing risk
Credit risk related to the company's ability to refinance and meet its debt obligations.
Mitigation methods
La stratégie de remboursement repose sur une cession des actifs lorsqu’ils auront atteint le stade RTB ou quasi-RTB (avant sécurisation des mécanismes de rémunération). La durée de développement des actifs est estimée entre 2 ans à 2 ans et demi, la durée de commercialisation des actifs est estimée de 6 mois à 1 ans. En cas de délais dans le développement, Performance 8 Energy pourra procéder à un refinancement en dette des actifs, ou faire rentrer un actionnaire en vue d’exploiter conjointement les actifs. Cette option annexe pourra également permettre le remboursement des investisseurs Total Energies Invest.
Regulatory risks
Risk of changes in regulations applicable to the sector, involving reductions in subsidies or new taxes with a significant impact on project revenues.
Mitigation methods
Le terrain a été sécurisé pour les 2 projets à développer, via des promesses de bail. Les études exploratoires de raccordement (non contractuelles) ont identifié des solutions de raccordement à un coût raisonnable. Cependant, les délais annoncés pour mettre à niveau le réseau environnant sont de 9 ans, ce qui pourrait compliquer le processus de cession des projets. NB : RTE annonce systématiquement des délais de 9 à 10 ans de mise à niveau du réseau lors des études exploratoires. Dans la pratique, les délais sont en général beaucoup plus courts.
