Luxembourg / Lyon / Vienna, 20 May 2025 – Marguerite, a pan-European infrastructure investor, has renewed its support to Nexun, a platform dedicated to developing utility-scale solar PV projects across Europe. Through its latest fund, Marguerite III, Marguerite has committed additional financing to accelerate Nexun’s growth and strengthen its presence across key European markets.

The renewed commitment reinforces Marguerite’s strategic vision to invest in the energy transition and support the deployment of clean, domestically-produced energy. The additional funding will enable Nexun to consolidate its footprint across multiple geographies and expand its project pipeline, which already includes over 1.2 GW of solar PV capacity under development.

Initially launched in January 2023 with the backing of Marguerite, Nexun has quickly emerged as a leading player in the solar PV sector. With a team of 42 professionals operating across France, Austria, Spain, Poland, Germany, and Italy, Nexun focuses on early-stage project origination and permitting, to deliver high-quality, ready-to-build assets. In parallel, Nexun has also expanded its scope to develop battery energy storage systems (BESS), co-located solar PV + storage projects and in specific cases, like in northern Germany hybrid solar + wind projects, supporting the integration of renewable energy into the grid and enabling more flexible and resilient energy systems.

“We are proud to continue supporting Nexun’s growth trajectory. Under the leadership of its founders, Josef Kastner and Chloé Durieux, and with a highly talented team across Europe, the platform has consistently demonstrated strong execution capabilities. Nexun is well-positioned to play a meaningful role in advancing Europe’s energy transition,” said Guillaume Rivron, Managing Partner at Marguerite.

“We appreciate working with Marguerite agreeing in advance on a long-term strategy for each of our countries. Having a strong sponsor, we can focus on growing the company and our pipeline. We keep being agile, adapting to market needs and regulation changes, and integrating new technologies like BESS and hybridisation. We are excited to further support Europe on its energy transition path, ensuring independent, clean and cheap energy,” said Josef Kastner, CEO of Nexun.

The transaction underlines Marguerite’s long-term approach and its focus on enabling the development of strategic infrastructure in line with Europe’s climate and energy goals.
