NPM has transformed the six raw GB distribution network connection datasets into one file, NPM Parsed Excel, in order to analyse the latest developments across the grid.

NPM analysis of the entire dataset can be found in NPM Analysis PDF which along with raw and parsed data, can be found here.

Key takeaways from UK distribution network analysis for >50kW projects (July 2024 to October 2025):

• By October 2025, 7,892 projects totalling 42.23 GW of capacity are fully connected to the electricity distribution network, with an additional 2,591 projects accepted to connect, equating to 103.6 GW.
• Since July 2024, the number of connected projects rose by 9.44% (from 7,211 to 7,892), while accepted projects saw a 39.47% decrease (from 4,281 to 2,591), the decrease being the biggest in the past month (from 3,881 in September to 2,591 in October).
• Looking deeper into the decrease, National Grid Electricity Distribution’s (NGED) accepted to connect numbers dropped sharply in October because the new grid connection reform replaced the old first come system with a stricter “first-ready, first-connected” process, which removed or downgraded many unready or speculative projects. In short, the drop reflects a deliberate queue clean-up, not a fall in demand.
• Connected capacity grew by 19.13% (from 35.45 GW to 42.23 GW), and accepted capacity had a 30.86% decrease (from 149.87 GW to 103.60 GW) mainly because of the NGED’s reform.
• Across the busiest distribution networks, NGED leads with 275 projects accepted to connect and over 5,259 projects connected, while Scottish and Southern Electricity Networks (SSEN) manages over 722 accepted projects and over 698 connected projects.
• Among sectors, solar dominates by project number with 5,643 projects (46.34 GW), followed by onshore wind with 1,411 projects (15.12 GW), and storage with 1,048 projects (55.47 GW).
• By region, England tops the charts with 76.43 GW accepted and 30.22 GW connected. Scotland follows with 22.06 GW accepted and 6.64 GW connected. Wales remains lower with 1.3 GW accepted and 2.78 GW connected.
• Low Carbon and BSR lead in terms of the number of accepted to connect projects, with 36 and 33 projects, respectively, followed by Conrad with 25 projects, OPDE with 18 projects, and DNO with 18 projects.
• In terms of capacity, BSR dominates with 2.87 GW, Bluestone follows with 2.47, then Green Switch Capital with 1.49 GW, and Low Carbon with 1.04 GW.
• North Yorkshire leads on a county level in accepted-to-connect, West Yorkshire follows, Essex comes after.
