Solar Refinancing Deals
Sonnedix Has Secured a €730m Financing Package Across Four Markets

Sonnedix closed a €730 million financing package to refinance, optimize and develop its Southern Europe solar assets across France, Italy, Portugal and Spain, supporting approximately 540 MW of PV capacity and two battery energy storage assets. Italy accounts for the largest share of the allocation, with more than 350 MW, reflecting the company's continued growth momentum across the region.
The financing, backed by a consortium including ING, Santander CIB and Société Générale, strengthens Sonnedix's platform for expanding its hybridization strategy by developing storage projects alongside existing solar portfolios to reach new customers and improve grid flexibility. The deal builds on Sonnedix's broader footprint as a global renewable energy company with 12 GW of capacity.
This financing signals that integrated hybridization strategies are becoming central to scaling renewable energy platforms across Europe's most established solar markets.
