The project
Accompanying the energy transition in the Occitanie region
In the Aude, Gard and Hérault departments , Dev’EnR, a company itself based in the heart of Occitanie, is currently developing 6 battery storage projects. All projects have secured land, a key step in the development of renewable energy projects, and two of them have already obtained their construction permits.
With a total capacity of 50.3 MW, the projects will ultimately have a storage capacity of 100.6 MWh.
By mid-2028, the 6 projects are expected to reach the Ready-to-Build (RTB) stage , allowing Dev’EnR to sell them. With a sale price in line with market standards (€80k/MW), the group anticipates a project portfolio valuation of €4 million.
Project example
In the Hérault department, Dev’EnR has applied for a construction permit for a stationary battery energy storage system with a power of 3.4 MW and a storage capacity of 6.8 MWh . Thanks to financing from Total Energies Invest, it hopes to reach the Ready-to-Build (RTB) stage by mid-2027.
With this project, the company will directly participate in RTE’s System Services (primary and secondary reserves), thus ensuring the balance and stability of the national and European electricity grid.
Below is a simulation of the project as it is expected to be implemented:
BESS storage, a booming market
The French electricity grid is currently undergoing significant transformation , with the increasing share of intermittent renewable energies (solar, wind) and the reduction of conventional controllable means (thermal, etc.). The grid must permanently maintain the balance between supply and demand and the frequency at 50 Hz, in a more volatile context. Battery storage (BESS) is particularly well-suited to this need, providing immediate (milliseconds) and bidirectional (charge/discharge) flexibility.
In France, the pace of BESS development is significantly lower than that of its European neighbors: only 1.8 GWh of storage capacity is expected by 2027, less than in Ireland. However, RTE has indicated a strong willingness to invest heavily in this type of solution.
The shift to a 15-minute interval, the rise of renewable energies and the growing need for flexibility make battery storage structurally essential , provided there is rigorous development, advanced management and an appropriate strategic positioning.
💡 Did you know?
Since October 1, 2025, the electricity “spot” market has moved from hourly to 15-minute intervals: meaning that the price of electricity is now set for each quarter-hour rather than each hour. This change has significant impacts on price volatility, with much more granular variations.
This shift to 15-minute intervals is particularly favorable to BESS-based strategies, as batteries benefit from high responsiveness and can react more finely to price variations than other types of energy storage systems. It is estimated that revenues from electricity trading on the day-ahead spot market for a BESS asset could increase by 10% to 25%.

Dev'EnR, a human and local approach
Committed to the development of renewable energies, Dev'EnR co-builds its power plants with local stakeholders to offer sustainable and tailored energy solutions for the needs of the territories. With a strong regional presence, Dev'EnR actively contributes to the energy transition by carrying out environmentally respectful projects and creating positive synergies with local stakeholders.
The company, which currently employs around sixty collaborators, operates 16 photovoltaic power plants and plans to have an installed capacity of more than 100 MWp by the end of 2027. To date, the developed projects represent nearly 1 GWp in Occitanie but also in the Nouvelle Aquitaine, Auvergne Rhône Alpes, and Bourgogne Franche Comté regions.
Beyond the numbers, it is our way of acting that sets us apart:
· Our projects are designed with elected officials, citizens, and farmers, taking into account their specific challenges
· We combine local governance, participatory financing, and active consultation
· We pay particular attention to the landscape integration of each of our projects
A few years ago, a movement of concentration among historical players in the renewable energy sector considerably reduced the number of agile and human-sized companies in this industry. Yet, it is the human relationships, proximity, environment, and commitment to a cleaner and more territory-focused world that form the DNA of renewable energies, and it is in this approach that Dev'EnR is engaged.
Our analysis
Risk overview
Development risk
Risk relating to authorizations issued to the company and land, and third-party appeals against authorizations issued.
Mitigation methods
With proven expertise in the implementation of solar power projects, and having recently brought three battery storage projects to the construction-ready stage, the Dev’EnR Group possesses the development capabilities needed to mitigate connection and permitting risks.
Refinancing risk
Credit risk related to the company's ability to refinance and meet its debt obligations.
Mitigation methods
Four of the six projects in the portfolio are in advanced stages of development and therefore pose lower risks regarding their potential resale within the projected timeframe. In addition, outside of this portfolio, Dev’EnR has more than 50 MW of battery storage projects in advanced negotiations, which could replace a failing project if necessary.
Operating risks
Risk related to an activity that depends on a limited number of key persons responsible for carrying out the planned strategy. The risk is that one of these key persons leaves the project.
Mitigation methods
The Dev’EnR Group has forged strong ties with reputable regional financial institutions (Crédit Agricole, OCCTE) to receive support for its operations and growth.
