What changed between editions

Changes to sites found in both of two consecutive monthly editions.

September 2026 edition to October 2026 edition 0 changes

1,021 sites matched. 40 sites couldn't be matched between the two editions, because their details changed or they appear in only one.

No changes found.

Grid supply points in the October 2026 edition

Each grid supply point the edition names, the largest first, with the capacity of its sites connected and accepted to connect.

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.

Price my project

Get the plan that holds up best for your site, and where that answer flips.

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.

Flexible connection

The network operator can reduce how much power the site exports or imports when the local network is busy, usually in return for connecting sooner or more cheaply.

Yes: the register says it has one. No: the register says it doesn't. Not stated: the register leaves it blank.
