Grid reform now faces the harder test of physical delivery. Engineering capacity, high-voltage equipment, construction access, and commissioning resource will decide how quickly renewable and storage projects can connect.
Austrian Power Grid is progressing its €140m Ernsthofen substation upgrade. The project includes 220kV switchgear renewal, three new 220/110kV transformers, and a fully digitised regional control room supporting Austria’s transmission operation.
E.ON invested €1.4bn during the first quarter of 2026 while confirming its full-year outlook. The spending underlines the continuing scale of European network modernisation as electrification, grid digitalisation, and connection growth reshape energy infrastructure.
Portugal’s renewable build-out is being constrained by grid capacity.
Sheerness is receiving a major distribution network capacity upgrade.
National Grid has raised its five-year network investment programme.
Austria may need more than €68bn of grid investment by 2040 as renewable electricity targets, regional network constraints, electrification, and system flexibility requirements reshape its energy infrastructure.
UK Power Networks’ Future Fleet project will model where electric HGV charging demand is likely to emerge, how local networks may be affected, and which flexible charging, storage, solar, and shared infrastructure models could reduce connection pressure.
The Great Sea Interconnector may require additional funding if a European Investment Bank assessment confirms higher project costs for the planned Greece–Cyprus–Israel subsea electricity link.
Ofgem has approved early construction funding for major Scottish transmission schemes, allowing network developers to secure grid components and advance enabling works ahead of final project approval.
