What would a delay do to this project?

QueueQuant tests this project’s options side by side: waiting for a firm date, taking a non-firm offer, private wire or off-grid supply. It runs each across a wide range of delay and curtailment outcomes, shows which option comes out ahead and where that ranking flips, and sizes every asset on the site for that option: grid capacity, battery power, on-site generation, private wire and backup. It also prices the downside, showing how bad the outcome gets in the worst futures at the risk level you choose.

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.
