Connectology Case - Theme 5: Leaving novations too late

The fifth and final episode in this series on grid connection challenges for data centre developers. Connectologist® Pete Aston details the modification application and novation process — and why leaving it too late can delay an entire project. • Most transmission connections start as private network connections — the original offer is issued to the developer entity directly, classed as a non-embedded demand customer by the NESO. •Switching to an IDNO requires a formal Mod App - a change of customer type cannot simply be requested; the process runs in two sequential stages and cannot be rushed • Timescales add up quickly — a Mod App takes around three months; the novation a further three to four weeks; the full transition is realistically five to six months • Securities are doubled during the changeover period — the developer holds securities with both NESO and the IDNO simultaneously, carrying a real financial cost • Start early — the Mod App process is the single most important thing to get moving to protect the connection timeline Recorded: 02 April 2026 Our links: Website: https://roadnighttaylor.co.uk/ Newsletter sign up: https://roadnighttaylor.co.uk/newslet...
