nLighten has entered into a Power Purchase Agreement (PPA) and supply deal with Shell Spain, which began on April 1, 2025. This collaboration will allow nLighten’s edge data center in Madrid, to be powered by Shell’s solar and wind portfolio in Spain, prioritising solar generation. The agreement goes beyond traditional renewable energy contracts by providing nLighten with transparency into the actual renewable energy supply received, rather than relying solely on financial credits such as Guarantees of Origin (GoOs).
Through this agreement, Shell will supply renewable capacity to nLighten, supporting the data center’s efforts to optimise its Carbon-Free Energy (CFE) score, while maintaining the flexibility to scale based on real-time supply and demand. During periods of lower renewable generation, Shell will manage the remaining energy supply to ensure uninterrupted operations. This approach guarantees energy reliability, while reinforcing nLighten's commitment to a more sustainable digital infrastructure.
"This agreement is a game-changer for how data centers in Spain – and beyond – can be powered by renewables," said Chad McCarthy, Chief Technology Officer and Co-Founder of nLighten. "By securing direct access to solar and wind energy, we’re not just reducing our carbon footprint but proving that sustainability and business performance go hand in hand. This supply agreement with Shell is important in building a resilient and future-proof energy model for digital infrastructure."
In addition to environmental benefits, this agreement highlights the economic advantages of renewable energy integration. As energy markets continue to evolve, the ability to integrate renewables into data center operations positions nLighten at the forefront of both sustainability and cost-efficiency efforts.
"We are excited to partner with nLighten to advance the integration of renewable energy in data centers," says Óscar Fernández, Shell Spain Country Chair. "By integrating lower-carbon sources into the grid, providing flexibility options and offering tailored energy solutions, we can support the growing demands of data centers. Strategic collaborations between digital infrastructure companies and energy suppliers allows to leverage each other's strengths, helping scale solutions quickly and effectively to ensure a sustainable energy supply."
This partnership is a significant step in nLighten’s journey to redefine the energy model for European data centers. By collaborating with industry leaders like Shell, nLighten demonstrates the industry’s continuous transition to a cleaner energy model.
