NHOA Energy, a division of NHOA Group (NHOA.PA), has initiated the execution of a major project with Red Eléctrica, Spain's transmission system operator (TSO), to deploy two large-scale battery energy storage systems (BESS) in the Balearic Islands.
The combined capacity of 140MW and 105MWh will enhance grid stability and will be the largest *Storage as Transmission Asset* (SATA) project in Southern Europe.
The BESS will be strategically installed at substations to strengthen the islands' electricity supply, ensuring continuous service and improving the efficiency of current and future interconnections with Mallorca.
This initiative aligns with Spain's broader goals for renewable energy growth, emissions reduction, and increased energy independence, as outlined in the National Integrated Energy and Climate Plan (PNEIC).
The project forms part of Spain’s broader electrical planning efforts to foster economic growth and sustainability by decarbonizing the energy sector, with the storage systems playing a pivotal role in managing energy transitions across the region.
“We are grateful to Red Eléctrica for the award of this landmark contract. The 140MW project is a game changer for the entire region, representing the EU’s largest smart grid battery storage initiative, "commented Fabrizio Ciaccia, Vice President EMEA of NHOA Energy.
"By strengthening the interconnection between the islands and the mainland, the project shows how integrated energy storage solutions can be effectively implemented to foster the resiliency of national grids, in every landscape, especially in critical areas. ”
