Sonnedix and Endesa have signed a tailor-made financial product to hedge solar and storage positions starting in 2027.
Sonnedix said the agreement covers 262.8GWh of renewable energy across its portfolio in Spain and Portugal.
The company added that the deal marks its first hybrid product, combining solar photovoltaic generation with battery energy storage systems as part of its strategy.
The transaction is designed to optimise energy management and provide a flexible supply profile aligned with customer demand.
Sonnedix said the agreement represents a milestone in its hybridisation strategy and coincides with the commissioning of its first battery storage systems.
“This agreement with Endesa reflects the evolution of the energy market toward increasingly sophisticated solutions tailored to the real needs of consumers,” said Axel Thiemann, chief executive of Sonnedix.
“The integration of renewable generation and storage is key to advancing toward a more flexible, efficient, and future-ready system.”
“This type of tailor-made product represents a step forward in structuring renewable supply,” said Gregorio Morales Schmid, chief commercial officer of Sonnedix.
“By combining solar generation and storage, we can offer greater predictability in supply, optimize energy management, and generate sustained value for our customers, while also supporting their decarbonization goals.”
