The UK Grid Is Changing — But Planning Methods Haven’t

The UK is entering a new phase of infrastructure delivery.

Projects like the Eastern Green Link and multiple offshore wind grid connections are not just large — they are long, complex, and linear by nature.

We are now talking about:

  • Hundreds of kilometres of subsea and onshore HVDC cables
  • Multi-billion-pound investments
  • Interfaces across landfall, marine routes, substations, and converter stations

For example, the Eastern Green Link 3 alone includes a ~680 km HVDC cable system, forming part of a £3+ billion “electricity superhighway” connecting Scotland to England.

The Planning Problem No One Talks About

Despite the nature of these projects, many teams are still trying to plan them using traditional Gantt charts.

That creates real issues:

  • No spatial visibility of the route
  • Difficult coordination of crews along kilometres of alignment
  • Poor understanding of access constraints and work fronts
  • Limited ability to optimise production flow

In short: we’re using tools designed for buildings to plan infrastructure that behaves like a corridor.


Why This Matters Now

The scale is accelerating:

  • Multiple Eastern Green Link phases (EGL1, EGL2, EGL3, EGL4…)
  • UK-wide grid reinforcement driven by offshore wind expansion
  • Increasing pressure on timelines, costs, and resource efficiency

These are not isolated projects — they represent a systemic shift in infrastructure delivery.


This Is Exactly Why TILOS Exists

Linear infrastructure requires a different way of thinking.

TILOS (Time Location Scheduling) was designed specifically for:

  • Railways
  • Highways
  • Pipelines
  • Transmission lines
  • Cable corridors

It combines time + location in a single view, allowing planners to:

  • Visualise progress along the route
  • Optimise crew flow and productivity
  • Avoid clashes in linear work zones
  • Make decisions based on spatial reality — not just dates

A Shift That Planners Cannot Ignore

The UK grid upgrade is not just an engineering challenge.

It is a planning challenge.

And the tools we use will directly impact:

  • Delivery speed
  • Cost efficiency
  • Risk exposure

The question is simple:

👉 Are we adapting our planning methods to the projects we are delivering?

Or forcing new-generation infrastructure into outdated frameworks?
