- Coal and methane prices. Fuel prices are modeled as 12 values from a historical year, derived from this PUDL database: https://data.catalyst.coop/pudl/core_eia923__monthly_fuel_receipts_costs.
- ATB cases. The model uses the 2022 ATB, which has three scenarios: "Moderate", "Conservative", and "Advanced". We only use the "Moderate" case, here.
- Demand growth. This will be modeled as either 0.00 or 1.00.
- Exports. There's no toggle or setting for this -- rather the starting load determines whether or not the model is matching the in-state load or the in-state generation. For no export the starting value should be 136e6; for export it should be 185e6.

The order in the snakemake workflow of the rules we need to modify:
| Rule | Script |
|---|---|
| 3 | retrieve_costs.py |
| 4 | retrieve_fuel_prices.py |
| 11 | add_electricity.py |
There are no conservative or advanced cases for nuclear in the ATB, only moderate. As a result the model won't run for cases other than moderate, and we did not include a sensitivity around capital cost in the model.
