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.

  • 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
