Which markets South Dakota requests sit in
A state is a location, not a market. Requests at South Dakota 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 |
|---|---|---|---|---|---|
| West | 161 | 27 GW | 6.3% | 82.0% | |
| MISO | 121 | 30 GW | 6.1% | 77.9% | |
| SPP | 70 | 12 GW | 8.7% | 78.0% | |
| PJM | 3 | 5 GW | 0.0% | 100.0% |
By resource type
| Resource | Requests | Capacity filed | Reached operation | Withdrew | Outcome by capacity |
|---|---|---|---|---|---|
| Wind | 230 | 52 GW | 6.0% | 88.5% | |
| Other | 38 | 8 GW | 0.8% | 82.5% | |
| Solar | 34 | 5 GW | 4.2% | 55.0% | |
| Gas | 30 | 5 GW | 26.4% | 37.0% | |
| Battery | 12 | 2 GW | 0.0% | 67.8% | |
| Hybrid | 11 | 2 GW | 0.0% | 52.4% |
Hybrid covers requests the dataset records as a combination, such as solar plus battery.

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.
