- build_cost_data read the electric sector fuel costs of AEO2023 from PUDL, in 2022 dollars it did not convert. It now reads the AEO2026 Table 3 electric power prices of natural gas, steam coal and distillate fuel oil from the EIA API (eia.ProjectedFuelCost), and converts them from 2025$/MMBtu to 2023$/MWh_th. PUDL's AEO2026 table holds only nominal prices. - costs: aeo: scenario takes the AEO2026 cases. AEO2026 has no Reference case, so reference is its Counterfactual Baseline, and existing configs keep validating. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
- Existing gas, coal and oil plants, and the new units copied from them in later periods, paid their plant level fuel cost of EIA-923 2025 (PUDL), the same in every investment period. Only carriers without an existing plant used the AEO fuel costs of the cost data. - add_extra_components now sets the marginal cost of every gas, coal and oil plant in each investment period to its VOM plus that period's AEO fuel cost over its efficiency, unless conventional: dynamic_fuel_price is enabled. - Oil plants take the distillate fuel oil cost, which they lacked.
