What changed recently

Changes to the sites here found in both of two consecutive monthly editions, the latest first.

September 2026 edition to October 2026 edition: 109 sites matched. Every September site and every October site at this grid supply point had a match in the other edition.

No change to the status, capacity, technology or customer of the sites here in the editions of UKPN's register QueueWatch holds.

QueueQuant

Price what a delay would do to your project

QueueWatch reports what changed in the DNOs' published connection registers. It doesn't tell you what to do about it. That's what QueueQuant is for.

Give QueueQuant a site and it compares every way you could power it, on the grid or off it: waiting for the firm date, taking a non-firm offer, building a private wire or going off-grid, across every combination of contracted capacity, generation and battery. That’s millions of possible plans, each tested against thousands of possible futures for delay, curtailment and price. It returns the one plan that holds up best, even when that plan is not to build.

What you get from QueueQuant

  • The route to power that wins
  • How to size every asset on the site
  • The level of delay or curtailment at which that answer flips
  • Whether the project is worth building at all
  • How bad the worst outcomes get, at the risk level you choose

How power reaches a site

A grid supply point (GSP) is where the national grid hands power to the local network. A bulk supply point (BSP) steps it down to a lower voltage for an area. A primary substation steps it down again for the streets and sites nearby. Most small and medium sites connect at a primary. Not every network has all three levels.
