Distribution / ENWL / Grid supply point

HARKER ENWL SGTS 1 2 3A 4 / HUTTON GSP GROUP

Grid supply point in North West England (ENWL)

ENWL Embedded Capacity Register 2 – 1MW and above, September 2026 edition

ENWL's register names more than one grid supply point here, as one. QueueWatch keeps them together, as the register gives them, and does not split their sites between them.

The register spells this grid supply point more than one way: “HARKER ENWL SGTS 1 2 3A 4 / HUTTON GSP GROUP” (101 sites), “HARKER/HUTTON” (21 sites), “HARKER / HUTTON” (4 sites) and “HARKER HUTTON” (1 site).

Not found in ENWL's September 2026 edition

4 sites last found at this grid supply point were not found in this edition by their MPAN, grid reference or name and postcode. QueueWatch keeps their pages for six months and does not say whether they have left the register.

What changed recently

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

May 2026 edition to September 2026 edition: 122 sites matched. 9 sites at this grid supply point couldn't be matched between the two editions, because their details changed or they appear in only one.

No change to the status, capacity, technology or customer of the sites here in the editions of ENWL'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.
