OMV Petrom has moved Gabare into full project development phase. The Bulgarian scheme combines large-scale solar generation with 600MWh of battery storage, adding another hybrid asset to Southeast Europe’s flexibility pipeline.
-
Wärtsilä will place its storage business inside a joint venture. The RCT Solutions deal gives the BESS integrator a new structure as utility-scale storage faces tighter margins, deeper software requirements, and more demanding delivery expectations.
-
Allume’s SolShare update expands shared solar options for flats nationwide. The new system increases capacity, adds battery integration, and is set for UK installer availability from August 2026.
-
Weihenstephan’s electric depot links fleet charging with on-site storage control. The brewery has installed fast chargers, modular batteries, rooftop solar, and energy management for electric truck operations.
-
Germany’s grey co-location project links batteries with market optimisation models. Entrix will optimise a solar-plus-storage asset where the battery can charge from both PV and the grid.
-
Germany’s DC-coupled pilot tackles solar storage connection constraints head-on directly. Sigenergy, EnBW, and ZSW are testing whether DC architecture can reduce hardware needs and improve solar-plus-storage economics.
-
Czech pumped-storage plans revive hydro’s role in grid flexibility nationally. ČEZ will convert part of the Orlík hydropower complex into reversible pumped storage while modernising existing turbine units.
-
Romania’s compressed-air project revives focus on long-duration electricity grid storage. Airengy and Hagag Europe are targeting salt-cavern storage as Europe searches for alternatives to short-duration lithium systems.
-
Hungary’s largest battery project moves grid flexibility forward across Europe. Greenvolt’s Buj system adds nearly 289MWh of storage capacity to a market scaling fast from a low operational base.
