MISO · Market-wide
Each queue vintage got bigger, and less of it got built.
Market-wide queue vintages, 2014–2019
Six years of MISO interconnection requests: volume roughly tripled while the share reaching commercial operation fell from 30% to 7%.

The queue record
Every request this market received in each year, and how those requests had resolved by the end of the dataset.
| Filed | Requests | Built | Withdrawn | Still in queue | Median years to build |
|---|---|---|---|---|---|
| 2014 | 112 | 34(30%) | 76 | 2 | 2.6 |
| 2015 | 104 | 43(41%) | 53 | 8 | 3.9 |
| 2016 | 220 | 28(13%) | 177 | 15 | 3.4 |
| 2017 | 192 | 33(17%) | 127 | 32 | 4 |
| 2018 | 239 | 15(6%) | 165 | 59 | 4.3 |
| 2019 | 301 | 22(7%) | 152 | 127 | 4.2 |
What the record shows
- MISO received 112 interconnection requests in 2014 and 301 in 2019, roughly a tripling in six years.
- Of the 2014 vintage, 30% had reached commercial operation by the end of 2025. Of the 2019 vintage, 7% had.
- The 2016 vintage is the starkest: 220 requests, of which 177 withdrew and 28 were built.
- Median time from request to commercial operation rose from 2.6 years for the 2014 vintage to 4.3 years for 2018.
- 127 of the 301 requests filed in 2019 were still active at the end of 2025, so those vintages are not yet settled.
What a decision record would have to make explicit
- The later vintages are incomplete: requests still active may yet be built or withdrawn, so their built share can only rise.
- This dataset does not carry a point-of-interconnection name for MISO, so a node-level comparison is not possible here and the vintage view is used instead.
- A falling built share across vintages is a description of what happened, not an explanation. 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.
