The agreement is set to bolster income stability for Enhol and underscores the growing importance of PPAs as vital risk management tools in evolving electricity markets.

Axpo Iberia CEO Ignacio Soneira said: “The volume and duration of the agreement underline our ability to structure complex, large-scale transactions in an increasingly demanding energy environment.

“With the signing of this PPA, both companies are advancing their respective growth and consolidation strategies in the European renewable energy market, contributing to the development of a more stable, competitive and decarbonised energy system.”
