## Hybrid Renewables Gain Momentum in Spain Spanish renewable developer Zelestra and utility EDP have expanded their solar-plus-storage partnership with two new power purchase agreements (PPAs) that add battery storage to existing solar projects in Spain. Zelestra is the project owner while EDP acts as the offtaker. ### New Projects The Pedroso project pairs 31 MWdc of solar with a 25 MW / 100 MWh battery energy storage system, while the Valkyria project pairs 150 MWdc of solar with a 90.45 MW / 362 MWh BESS. Both batteries have a four-hour duration. The agreements bring the two companies' hybrid collaboration to four projects, with cumulative storage capacity exceeding 1 GWh. ### Fast Route to Grid Flexibility Hybridizing existing and new solar plants with battery storage is seen as a fast route to Spanish grid flexibility. Storage allows solar developers to shift generation to the evening and early morning hours, capturing higher prices and reducing the risk of curtailment as solar penetration rises. The expansion builds on previous deals between the two companies, including a July 2026 long-term tolling agreement covering a 300 MW share of a Zelestra storage asset. EDP is consolidating its position as a leading offtaker of storage-backed renewable energy in Spain, while Zelestra continues to expand its pipeline of hybrid assets across the Iberian market.
