IN Brief:
- Electrica has secured technical grid connection approvals for 17 BESS projects in Romania.
- The projects represent approximately 700MWh of storage capacity.
- The approvals define connection conditions and allow development to move toward execution.
Electrica has secured technical grid connection approvals for 17 battery energy storage projects in Romania, covering a portfolio of approximately 700MWh.
The approvals define the connection conditions required for the projects to progress into design, authorisation, and construction. Commissioning is targeted by the end of 2027, giving the portfolio a defined delivery window as Romania expands the flexible capacity available to its electricity system.
Grid approval is a decisive milestone for storage development because the commercial value of a battery depends heavily on where and how it connects. A project with land rights and equipment options remains exposed if the network cannot accommodate it. A project with defined technical connection conditions can move into more detailed engineering, procurement, financing, and permitting.
Romania’s storage market is expanding as renewable generation, grid constraints, and balancing needs increase. Battery systems can support renewable integration, frequency response, congestion management, and energy shifting, but they also compete for grid capacity with solar, wind, industrial demand, and conventional generation projects.
Electrica’s portfolio covers multiple sites rather than one single large asset. That structure can support flexibility across different network locations, reducing dependence on a single node and allowing storage to respond to local system conditions. It also requires a more complex operating model, with dispatch optimisation, maintenance planning, communications, and technical standards coordinated across several projects.
The Romanian approvals sit within a wider European acceleration in storage deployment. A separate wave of European battery projects totalling around 11GWh has shown how quickly storage is moving into mainstream grid planning across Germany, Poland, and Belgium. Romania’s 700MWh portfolio is smaller than those flagship projects, but it adds meaningful flexibility to a market still building its storage base.
The practical value of the portfolio will depend on duration, power rating, connection voltage, market access, and operational rules. A 700MWh energy capacity figure gives an indication of scale, but network value is determined by how much power can be injected or absorbed, for how long, at which connection points, and under which system conditions.
Battery projects also require careful electrical and safety engineering. A storage site brings together cells, racks, inverters, transformers, switchgear, battery management systems, thermal control, fire detection, civil works, protection, control software, and grid communications. Across a 17-project portfolio, consistency of technical design can reduce operating complexity, but each site will still need to respond to local grid and planning conditions.
Romania’s energy transition will need both additional generation and additional flexibility. Solar and wind can reduce reliance on fossil generation, while storage can help manage output variability and support system services. Without sufficient flexibility, renewable build-out can be slowed by curtailment, congestion, or weaker revenue certainty.
The end-2027 commissioning target leaves a demanding delivery path. Detailed design, planning permissions, equipment orders, civil works, grid interfaces, installation, testing, and commissioning must be managed across multiple sites. Long-lead electrical equipment, including transformers and switchgear, remains a constraint across Europe, making procurement strategy as important as technical approval.
Electrica’s connection approvals convert the portfolio into a more defined delivery pipeline. The next phase will show how quickly Romania can turn approved storage capacity into energised assets that can support renewable integration and network flexibility across the system.
