European electricity distribution investment is expected to reach €48 billion in 2027, according to the outlook cited alongside rising pressure on networks. The spending trajectory is linked to expanding renewable generation, battery storage and electricity demand. As those factors increase connection needs, distribution infrastructure faces growing demand for reinforcement and new access.
Across the EU and Norway, annual spending increased from €24 billion in 2021 to €36 billion in 2024. Additional investment is expected to be required to connect new projects and to reinforce infrastructure built for a more decentralised system. Connection requirements are presented as a key driver of the additional build-out need.
Connection queues highlight scale of network access demand
Connection applications illustrate the size of the challenge for grid operators. Italy has about 348 GW of variable renewable capacity seeking network access. The same market also has approximately 277 GW of storage applications at transmission level.
Germany’s storage queue is described as roughly 480 GW. The figures are said to exceed the capacity likely to be built, with applications including speculative or overlapping projects. Even so, the data point to a mismatch between project pipelines and available network access.
Utility-scale storage growth continues into early 2026
Operational utility-scale storage across the EU more than doubled during 2025. By early 2026, it reached about 11.2 GW. Germany accounted for approximately 2.9 GW of that total.
The source material links ongoing connection delays to constraints beyond funding levels. Permitting processes, equipment availability and labour shortages are identified as limiting factors. It also notes that the speed at which regulated operators recover investment costs remains a constraint on delivery timelines.
Developers’ value tied to connection timetables
For developers, the commercial value of a renewable or storage project increasingly depends on securing a credible connection timetable. That requirement sits alongside land, permits and financing needs. In this context, connection scheduling is treated as a key variable for project planning.
The discussion also frames network access as central to whether new capacity can proceed from application stages into development. It highlights that expanding renewable generation, battery storage and electricity demand are contributing to the pressure on distribution grids.
The same set of constraints is presented as relevant across both connection queue dynamics and operational build-out timing. Funding alone is described as insufficient to resolve delays tied to permitting, equipment supply and workforce availability.
