The project
A site for energy storage will soon be installed in the municipality of Billy-Berclau
The Billy-Berclau project involves the installation of a battery storage park with a capacity of 50 MW in the Pas-de-Calais region. With a construction permit that is final and all necessary authorizations secured, the project is set to be built once suppliers and partners have been selected by the sponsor Qair.
Located 1.8 km from an RTE connection point, it is expected to be commissioned in spring 2029.
BESS Storage: A Strategic Market
With the increasing share of renewable energies (solar and wind) and the reduction of conventional controllable means (particularly thermal power), the French electricity grid is undergoing a major transformation: it must store excess energy to redistribute it during peak demand, provide grid support services, and shift renewable energy production hours to better integrate them and smooth out daily electricity price fluctuations.
In this context, battery energy storage systems (BESS) are particularly well-suited, offering immediate (millisecond-scale) and bidirectional (charge/discharge) flexibility. The public grid operator RTE (Réseau de Transport d’Électricité) has indicated a strong willingness to invest heavily in such solutions. The growth of renewable energies and the rising need for flexibility make battery storage structurally essential.
A battery storage park operates on two key principles: absorbing excess energy produced by the grid and injecting stored energy to compensate for any shortfalls .
A Rapidly Expanding Group
QAIR International is the parent company of the QAIR Group, which was founded in 2017. With nearly 780 employees, the group now has around 1.7 GW of projects under construction and in operation , as well as a significant number of projects in development.
The group’s strategy focuses on wind and solar energy. Additionally, it is working on energy storage projects with a substantial development portfolio and innovative solutions related to renewable energies (hydrogen, tidal power, offshore wind, etc.).
By 2027, the company aims to achieve an operational capacity of nearly 2.5 GW, which will more than double by 2030 to reach over 5.5 GW.
For Qair International, entering the storage market represents a real opportunity for diversification while addressing the energy needs of the region.
The financing of the Billy-Berclau project will add to the ambitious projects already funded by Qair through Total Energies Invest: since the start of our collaboration, over 50 million euros have been raised from investors via Total Energies Invest and repaid by Qair .

Project owners
France
Qair International is an Independent Power Producer that currently has around 1.7 GW of projects under construction and in operation, as well as a large number of projects in development .
The group’s strategy focuses on wind energy, photovoltaics, hydrogen, and storage. At the same time, the group is also working on energy storage projects with a significant development portfolio and innovative solutions related to renewable energies (hydrogen, tidal power, offshore wind, etc.).
With an international presence spanning Europe, South America, and Africa, Qair employs nearly 780 people today, including 100 working for Qair France.
For over 30 years, the company has relied on the historical expertise of its specialists and the vision of its reference shareholder, Jean-Marc Bouchet.
The Founder’s Words, Jean-Marc Bouchet
The name Qair , shared by all our onshore and offshore wind, solar, hydroelectric, eco-combustion, and green hydrogen activities, reflects the unity of our group across the 21 countries where we develop projects. Qair evokes our roots (“Qa”), unites our international presence (“i”), and affirms our commitment to renewables (“r”). It encapsulates what we have been since the group’s creation over 30 years ago. The name also reflects the extraordinary era we live in, full of promise and challenges, where our growth must be sustainable, our progress lasting, and our development must not come at the expense of future generations. Since its inception, the group has recognized the environmental stakes and fully committed to actively participating in the ongoing ecological transition and accelerating, to the best of its ability, the environmental revolution I hold so dear.
“It is our duty to future generations to maintain our course as an actor committed to the environmental revolution!”
The Group’s Values
Our analysis
Risk overview
Construction risks
Risk related to errors or defects during assembly that may affect the final quality of the product
Mitigation methods
Given the nature of its business, QAIR benefits from a network of key partners, which should enable it to secure favorable rates for the construction of its power plants. The group’s expertise should enable it to surround itself with trusted partners for the construction of these projects, limiting assembly risks and ensuring some cost control through competitive bidding among various suppliers. However, Total Energies Invest should have little or no exposure to construction risk, as the construction of the battery farm is expected to take place at the end of the financing period and would be funded by the senior debt.
Refinancing risk
Credit risk related to the company's ability to refinance and meet its debt obligations.
Mitigation methods
The financial risk here is limited by two distinct factors. First, as of June 30, QAIR International reported consolidated cash and cash equivalents exceeding €100 million, reflecting the group’s ability to generate and secure its cash flow. On the other hand, as part of this financing, Total Energies Invest has secured two distinct forms of collateral: a pledge of 100% of the issuing company’s securities and a GAPD from QAIR France, the French project subsidiary of QAIR International. Through the GAPD, QAIR France thereby undertakes to settle Total Energies Invest’s debt on behalf of the issuing company in the event that the latter encounters difficulties in meeting its obligations. The financial risk is further mitigated by the group’s strategy and Qair International’s commitment to QAIR France, which aims to establish its French subsidiary as a major IPP over the coming years.
Market risk
Risk related to being in a competitive market where new players enter the competition each year
Mitigation methods
QAIR is pursuing a clearly defined growth strategy centered on the commissioning of multiple projects and the diversification of its business over the coming years. With nearly 1.7 GW of projects in operation, nearly 2 GW of projects in development on secured land, and nearly 780 employees, the group is experiencing rapid growth. Despite a competitive sector, QAIR is now firmly established in the French renewable energy market, backed by a strong network and a significant presence throughout the country. Financially, the group reports annual revenue from electricity sales of over 200 million euros, supported by fixed assets exceeding 1.3 billion euros. These two figures alone reflect the group’s position in the French market.
