© JUWIAthens/Paris/Wörrstadt (renewablepress) - JUWI, a wholly-owned subsidiary of MVV Energie AG, has signed an agreement with Mirova, an affiliate of Natixis Investment Managers dedicated to sustainable investing, for the sale of a 156-megawatt solar photovoltaic portfolio in Greece. Following the successful completion of the mergers and acquisitions (M&A) deal, JUWI has been appointed as the Engineering, Procurement, and Construction (EPC) and Operations and Maintenance (O&M) contractor for the entire portfolio. Construction is scheduled to commence in November 2025. JUWI Hellas has successfully developed Clover PV portfolio, with a total capacity of 156 megawatts (MW), taking a significant step toward a greener future.

The four projects comprising the Clover solar PV portfolio are located in the regional units of Kozani and Grevena, in Northwest Greece. With a total installed capacity of 156 megawatts, the portfolio represents a major step forward in JUWI Hellas’ commitment to utility-scale renewable energy development. JUWI Hellas will serve as the EPC contractor, overseeing the complete technical design, equipment procurement, and construction of the solar plants. Construction is scheduled to commence in November 2025. Upon completion, JUWI will also take on the O&M of the facilities, ensuring optimal performance, long-term reliability, and continued contribution to Greece’s clean energy future.

Once operational, the projects will generate over 300 million kilowatt-hours of clean electricity annually, enough to power more than 75,000 people. Collectively, the projects will deploy 243,500 bifacial solar modules, over 480 string inverters, and 9,100 single-axis trackers, spanning 257 hectares, an area equivalent to more than 350 football fields.


Internationally expanding renewable energies

With the successful completion of the Mirova transaction and the resulting assignment of the EPC and O&M contracts, ­MVV’s project development subsidiary, JUWI,once again demonstrates the strength of its diversified business strategy which combines both in-house development and acquisition of mature project rights. This approach has consistently delivered results, as seen in recent large-scale solar developments, including: the 204 MW solar park in Kozani, Greece, the 267MW solar portfolio in Domokos, Greece and the 223 MW “Pike” solar park in Colorado, USA.

“Following last year’s landmark sale of the Hive solar portfolio, the largest in our history, the successful closing of the Clover portfolio further reinforces our position as a leading developer in selected international markets. We are proud to deliver projects that not only meet the highest technical standards but also contribute meaningfully to the energy transition” says Stephan Hansen, COO of the JUWI Group and responsible for the international business.

“Over the past five years, JUWI Hellas has successfully completed M&A transactions exceeding half a billion euros and has established itself as Greece’s benchmark for utility-scale solar development and EPC execution. We’ve consistently demonstrated our ability to align strategic vision with operational excellence. The sale of the Clover portfolio to Mirova, along with the signing of the EPC and O&M contracts, marks another important milestone in our journey” says Takis Sarris, Managing Director of JUWI Hellas.

Helene Dimitracopoulos, Managing Director, Deputy Head of Energy Transition Infrastructure, emphasizes: “ This transaction perfectly illustrates our ambition with the investment strategy: to support high-quality developers in delivering large-scale, high-impact sustainable energy infrastructure. By investing in the Clover portfolio, we are strengthening our presence in Southern Europe and making a concrete contribution to Greece’s energy transition, while targeting top-tier environmental and technical performance.”

For the successful completion of the transaction with Mirova, JUWI Hellas collaborated closely with the esteemed law firm Karatzas & Partners. “We sincerely thank K&P for their dedication, professionalism, and unwavering commitment throughout the process,” said Takis Sarris, Managing Director of JUWI Hellas.
