What changed recently

Changes to its sites found in both of two consecutive monthly editions of their DNO's register, the latest first.

NGED: QueueWatch holds one edition of its register so far, the August 2026 edition, so there is nothing to compare yet.

No change to the status, capacity, technology or customer of its sites in the editions 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.

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

How to size every asset on the site
