Greenvolt said the project, which took 20 months to complete, will be integrated into the biomass plant’s control system and “modulate generated power” from the plant.

João Andrade, technical director for Greenvolt Group, commented: “This project is a testament to our commitment to continuous improvement in the performance of our renewable energy production facilities”.

Most large-scale BESS projects in Portugal in recent years have been on its islands, including a 15MWh project on Terceira and a 16.4MWh one on Madeira, both deployed by the world’s largest BESS integrators Fluence.

On the mainland, of which Coimbra is part, utility Iberdrola inaugurated the 40GWh Tamega pumped hydro energy storage (PHES) project was inaugurated last year.

Greenvolt’s origins are as a biomass company in Portugal but it has since expanded into renewable energy development and operation more broadly, and is active across Europe and the US. In July, it acquired a 125MW solar, 50MW battery storage project in New Mexico, expected to come online in 2025.

Energy-Storage.news’ publisher Solar Media will host the 9th annual Energy Storage Summit EU in London, 21-22 February 2024. This year it is moving to a larger venue, bringing together Europe’s leading investors, policymakers, developers, utilities, energy buyers and service providers all in one place.
