Renalfa Power Clusters has acquired two late-stage renewable energy projects in western Romania’s Arad County, with a plan for further investment.
The first asset is the 365 MWp Horia 2 solar power plant, while the second is a nearby 400 MW/800 MWh standalone battery energy storage system (BESS).
Renalfa intends to combine and merge them into a single hybrid power cluster, targeting a commercial launch in 2027. The announcement said the projects are “fully derisked and in late-stage development”.
In addition to the acquisition, Renalfa plans to expand the combined Horia-Arad site in two stages, and bring in a hybrid dual-chemistry approach, mixing lithium-ion storage and sodium-ion storage, while adding in grid-forming technology as well.
The first phase will lift solar capacity to 568 MWp and increase the BESS to 669 MW / 2,000 MWh.
A second phase will add another 400 MW / 1,608 MWh standalone BESS with the company also stating it could “potentially” be in combination with more PV. This would take the total storage capacity to 3.6 GWh.
