ISO-NE · Market-wide

The built share barely moved — and no completion date is recorded at all.

Market-wide queue vintages, 2014–2019

Six years of ISO-NE interconnection requests: the share reaching commercial operation stayed between 17% and 28%, while the dataset records no in-service date for any ISO-NE project.

The queue record

Every request this market received in each year, and how those requests had resolved by the end of the dataset.

Interconnection requests by the year they were filed, with how many had been built, withdrawn or were still active at the end of the dataset.

What the record shows

  • ISO-NE received 39 interconnection requests in 2014 and 99 in 2019, peaking at 117 in 2018.
  • The built share stayed in a narrow band across all six vintages, between 17% and 28%.
  • Withdrawals outnumbered completions in every vintage, by between two and five times.
  • None of the 228 ISO-NE requests recorded as operational carries an in-service date, so no time from request to operation can be computed for this market.
  • Fewer requests were left unresolved here than in the other markets in this set: 18 across six vintages.

What a decision record would have to make explicit

  • Because no in-service date is recorded for this market, ISO-NE cannot be compared with the others on time in queue. The column is shown as N/A rather than estimated.
  • ISO-NE is the only market in this set whose built share does not fall across these vintages, but a flat share over six years is a description, not a trend that can be projected forward.
  • The dataset records no withdrawal reasons.

What this does and does not show

This is a reading of a public dataset, not a customer case study: no engagement, customer or client is involved. The dataset records outcomes — what was built, what withdrew, and when — but not why any project withdrew, so no cause is attributed here. Nothing on this page claims GridVision predicted, influenced or would have changed any outcome, and a pattern at one point of interconnection does not generalise to another.
