Which markets Maryland requests sit in
A state is a location, not a market. Requests at Maryland 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 |
|---|---|---|---|---|---|
| PJM | 556 | 57 GW | 9.5% | 80.1% |

By resource type
| Resource | Requests | Capacity filed | Reached operation | Withdrew | Outcome by capacity |
|---|---|---|---|---|---|
| Solar | 289 | 6 GW | 9.4% | 66.4% | |
| Gas | 100 | 36 GW | 11.9% | 87.8% | |
| Battery | 76 | 6 GW | 0.1% | 45.5% | |
| Other | 54 | 6 GW | 4.3% | 95.7% | |
| Hybrid | 20 | 2 GW | 0.0% | 31.2% | |
| Wind | 17 | 2 GW | 18.4% | 77.0% |
Hybrid covers requests the dataset records as a combination, such as solar plus battery.

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 Maryland 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.
