nLighten Secures Traceable Renewable Energy Deal in France

nLighten has confirmed a new renewable energy procurement agreement that places traceable, carbon-free power at the heart of its French operations.

The deal will cover all of the company's data centre sites across France and is scheduled to commence on 1 January 2026.

This arrangement forms part of a broader European approach designed to enhance accountability and transparency in renewable energy consumption.

Rather than depending on annual certificates or generalised national energy data, the data centre operator now connects its power usage to specific renewable assets.

Francesco Marasco, Vice President of Energy Operations & Sustainability at nLighten, says: "This partnership represents an opportunity to fundamentally change how we approach energy procurement in France.

"While France's grid already benefits from significant carbon-free nuclear generation, this agreement puts us in the driving seat in terms of knowing exactly where our renewable energy comes from.

"It helps us maintain transparency and control over our energy sourcing, protecting us from potential changes in grid composition."

Hourly renewable energy tracking

The arrangement operates through a three-party structure involving Switzerland-based Axpo, the country's largest electricity producer, and an independent power producer (IPP).

Under this framework, Axpo manages the primary electricity supply to nLighten's French data centres while also overseeing renewable generation from the IPP's wind portfolio.

This renewable output is then allocated directly to nLighten.

This structure delivers two key outcomes: continuous power availability for data centre operations, even during periods of reduced wind supply, and dedicated renewable energy tracking from specific assets.

Axpo can provide supplementary power from alternative sources when necessary to guarantee uptime, while the IPP monitors wind power output in real time.

Through this level of traceability, nLighten can align electricity consumption with green generation on an hourly basis.

This method moves beyond traditional approaches, which typically depend on average grid data or retrospective renewable energy certificate purchases calculated annually.

The shift could enable data centre operators like nLighten to make more precise claims regarding their environmental performance.

For customers focused on sustainable operations, asset-specific and time-linked energy matching could provide stronger evidence of genuine renewable use.

Distinctive approach in French market

The supply model nLighten has adopted is already established across other European energy markets.

Countries including the UK and Germany support comparable flexible energy procurement structures that combine base load power with traceable renewable inputs.

In France, however, this approach remains relatively uncommon.

Whilst nuclear energy constitutes a substantial portion of the national energy mix, agreements that track renewable power hourly from specific wind farms are still limited.

Matthieu Espinas, Senior Originator at Axpo, says: "We're proud to support nLighten's ambitious sustainability goals through this innovative supply model.

"By combining the reliability of traditional energy supply with transparent renewable generation tracking, we're helping to bring new levels of accountability to the French data centre market.

"This partnership demonstrates that flexible, transparent energy solutions are not only possible but also commercially viable in France."

The integration of this model in the French market not only delivers greater visibility into the origins of nLighten's power but also contributes to a wider shift in how energy transparency can function within critical infrastructure such as data centres.

Broader European procurement strategy

nLighten's recent move in France aligns with a wider European procurement strategy.

The company already operates similar agreements with Shell in Spain and Conrad Energy in the UK.

Each of these partnerships follows the same core principle of granular, asset-linked renewable tracking, adapted according to individual country regulatory environments and market structures.

Rather than relying on less detailed annual tracking systems, nLighten's portfolio approach supports direct connections to specific renewable sources, promoting consistency and accountability across borders.

By implementing this strategy throughout its network, nLighten not only aligns with stricter internal sustainability objectives but also encourages the European data centre sector towards more transparent and verifiable power sourcing practices.

The French agreement serves as a practical demonstration of how a data centre operator can restructure energy procurement to better satisfy both environmental expectations and operational requirements.

Through consistent partnerships and real-time tracking tools, nLighten maintains a clear understanding of its energy use and its environmental impact.
