Which markets Iowa requests sit in
A state is a location, not a market. Requests at Iowa points of interconnection are studied by the market that runs the queue there, and the process differs between them.
| Market | Requests | Capacity filed | Reached operation | Withdrew | Outcome by capacity |
|---|---|---|---|---|---|
| MISO | 480 | 97 GW | 12.7% | 63.0% | |
| West | 20 | 2 GW | 9.9% | 90.1% | |
| SPP | 4 | 341 MW | 0.0% | 21.7% | |
| PJM | 2 | 3 GW | 0.0% | 100.0% |
By resource type
| Resource | Requests | Capacity filed | Reached operation | Withdrew | Outcome by capacity |
|---|---|---|---|---|---|
| Wind | 288 | 52 GW | 20.2% | 65.9% | |
| Solar | 64 | 9 GW | 1.6% | 45.7% | |
| Other | 53 | 15 GW | 1.6% | 90.0% | |
| Gas | 45 | 17 GW | 9.0% | 54.9% | |
| Battery | 40 | 6 GW | 0.0% | 40.6% | |
| Hybrid | 16 | 3 GW | 0.0% | 69.4% |
Hybrid covers requests the dataset records as a combination, such as solar plus battery.

Recent years are unsettled: requests filed in the last few years may still be built or withdrawn.
Points of interconnection with the most requests

Names are as the dataset records them, so spelling variants of one station can appear separately.
Method and limits
Each request is counted once, at the capacity and status the dataset records for it, and placed in the state the dataset gives for its point of interconnection. Requests missing a state, status, filing year or capacity are left out. The dataset records outcomes and dates, not reasons, so nothing here says why a request withdrew, and no share is a rate to plan against.

Want this reading for a Iowa point of interconnection?
Send the node and the market. We read the public queue record for it — what was filed, what was built, what withdrew and how long each took — and send back what the record does and does not show.
