IN Brief:
- Distribution-level connection queues across eight European markets now include around 375GW of renewable energy projects and 455GW of battery storage projects.
- Solar PV accounts for the largest share of applications, while battery storage queues are expanding rapidly.
- Grid access, connection transparency, and distribution-level reinforcement are becoming decisive factors in Europe’s clean-energy build-out.
Beyond Fossil Fuels has published research showing that distribution-grid access is delaying hundreds of gigawatts of renewable energy and battery storage projects across Europe.
The analysis, prepared by AFRY, covers Bulgaria, Czechia, Great Britain, Germany, Greece, Italy, Poland, and Spain. Across those eight markets, around 375GW of renewable energy projects and 455GW of battery energy storage projects are waiting in distribution-level connection queues.
The report focuses on projects larger than 1MW that have formally requested distribution-grid access and are either awaiting assessment or approved but not yet commissioned. It estimates that approximately €100bn of clean-energy investment is effectively held up by connection delays, with solar PV accounting for around 70% of the queued renewable project applications.
Although transmission constraints have dominated much of Europe’s power-system debate, the figures show how quickly the pressure has moved into distribution networks. Large volumes of solar, storage, EV charging, heat pump, and commercial electrification assets connect below the transmission layer, where local substations, feeders, transformers, protection systems, and operating procedures determine how much capacity can be absorbed.
Connection queues vary widely by country, with each market facing a different mix of network capacity limits, administrative workload, project speculation, regulatory design, and queue transparency. Even so, the same pattern runs across the report: distribution system operators are being asked to process more applications, integrate more variable generation, and accommodate more flexible assets than legacy connection processes were designed to handle.
A similar pressure point is already visible in Denmark, where Energinet paused new Danish grid connection agreements after demand requests exceeded near-term network capacity. In parallel, ENTSO-E’s work on data-centre grid pressure has highlighted the way large loads are adding voltage, reactive power, capacity, and flexibility challenges to the same constrained system.
Battery storage is becoming a larger part of the distribution-grid equation. Co-located and standalone batteries can reduce curtailment, shift renewable output, support balancing services, and help optimise use of constrained connections. Across Europe, renewable and battery pipelines are expanding together as developers respond to negative pricing, local congestion, and tighter grid conditions.
Storage does not remove the need for stronger and more transparent connection processes. A battery can improve the way capacity is used, but the project still needs an agreed connection, suitable protection, operational visibility, control arrangements, metering, and market access. Where queues remain opaque or slow, capital remains tied up before engineering can move into delivery.
Digital connection portals, hosting-capacity maps, active network management, flexible connection agreements, and more consistent queue management are becoming part of the distribution-network toolkit. Physical reinforcement remains essential, but faster project screening and clearer technical requirements can prevent viable projects being delayed alongside speculative or underdeveloped schemes.
The report frames distribution networks as active clean-energy infrastructure, rather than downstream assets that simply receive power from the transmission system. Europe’s renewable and storage targets now depend on how quickly local networks can translate connection applications into energised assets.
