Sonnedix, a global renewable energy company with 12GW of total capacity, has closed a financing of €730 million for the refinancing, optimisation and construction of assets across several of Sonnedix’s core markets, France, Italy, Portugal and Spain. The financing showcases Sonnedix’s continued growth across Europe, and the continued trust and collaboration with its partners.

The financing will be allocated across assets in the four countries, including PV plants with a combined capacity of approximately 540MW and two BESS assets. Italy accounts for the largest share of the allocation, representing more than 350MW of capacity.

By refinancing these assets, Sonnedix has also built a strong platform from which to expand its hybridisation strategy, develop storage projects alongside its solar PV portfolio, and reach new customers.

The transaction has been formalised with the participation of AIB, CACIB, CIBC, ING, Intesa Sanpaolo, Sabadell, Santander CIB, Societe Generale, and UniCredit.

This transaction reinforces Sonnedix’s growing momentum across Southern Europe and its leading role in integrating battery storage solutions across its portfolio. It supports Sonnedix’s broader hybridisation strategy and strengths the flexibility, resilience, and value of its renewable energy platform.

Axel Thiemann, CEO of Sonnedix, said: 'This financing reflects Sonnedix's commitment to developing high quality renewable projects in our strategic markets. It follows our recent BESS portfolio acquisition in Italy, and underscores the pace at which we are scaling our storage capabilities across Europe.'

Miguel A. García Mascuñán, CFO of Sonnedix said: 'A €730 million financing is a major milestone for Sonnedix, offering significant financial flexibility and capacity to accelerate our development pipeline across core markets. This also reflects the continued trust and confidence of our partners, and we are proud to continue building on these relationships.'
