Delays and exits in the transmission queue since 2021How often connection dates move, and how many projects leave the queue. Gate 2 in the transmission queueHow much of the queue has a Gate 2 offer, and what it did to connection dates. The battery queue and CMP470’s commitment feeHow far the battery queue sits above the line that would switch CMP470’s commitment fee off. Changes of customer in the transmission queueHow often connection agreements move between companies, and how those projects fared. Do projects connect on time?How late stages have connected against their connection date in the register. Which connection dates slip least?Which connection dates are pushed back least, allowing for how far ahead they are. Grid outages and the connections due by 2030How many of their planned outages the transmission owners carry out, against the connections due by 2030.

QueueQuant

Price what a delay would do to your project

QueueWatch reports what changed in the public TEC register. 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

Status definitions (NESO)

Scoping: NESO is not aware that a planning application has been made.

Awaiting Consents: NESO is aware, or the customer has told it, that a planning application has been made.

Consents Approved: NESO is aware, or the customer has told it, that the planning application has been approved.

Terminated: used by NESO only in its register of 30 April 2021, for two projects that left the register the next month.

These statuses are NESO’s, not QueueWatch’s, and NESO describes them as “as far as we are aware”, so a project may be further along than its status shows.
