Utility-scale sodium-ion arrives in Romania
Why it matters: Romania will see a 365 MWp solar plant and 400 MW/800 MWh battery storage operational by 2027.
- Renalfa Power Clusters acquired the 365 MWp Horia 2 solar power plant and a 400 MW/800 MWh standalone battery energy storage system in Romania's Arad County.
- Renalfa plans to combine these assets into a single hybrid power cluster, targeting a 2027 commercial launch.
- The company will expand the Horia-Arad site in two stages, integrating a hybrid dual-chemistry approach using both lithium-ion and sodium-ion storage, along with grid-forming technology.
Renalfa Power Clusters has acquired two late-stage renewable energy projects in western Romania, the 365 MWp Horia 2 solar plant and a 400 MW/800 MWh battery storage system, with plans to merge them into a hybrid power cluster launching in 2027. The company intends to expand the site further, incorporating a dual-chemistry approach with both lithium-ion and sodium-ion storage, alongside grid-forming technology.
