Additional Details
This table includes NREL's projections for capital and operational costs as well as operational attributes for a variety of technologies for each of the NREL ATB scenarios. Each new year of ATB data includes projections for the next 25 years.
All of the NREL tables are related. If you want to understand the financial assumptions of a given scenario in this table, see core_nrelatb__yearly_projected_financial_cases. The other two core_nrealatb tables include attributes about technologies in these projections.
Columns
Four-digit year in which the data was reported.
NREL's financial assumption cases. There are two cases which effect project financial assumptions: R&D Only Case and Market + Policies Case. R&D Only includes only projected R&D improvements while Market + Policy case includes policy and tax incentives. https://atb.nrel.gov/electricity/2024/financial_cases_&_methods
NREL's tax credit assumption cases. There are two types of tax credits: production tax credit (PTC) and investment tax credit (ITC). For more detail, see: https://atb.nrel.gov/electricity/2024/financial_cases_&_methods
The year of the projected value.
High level description of the technology used by the generator to produce electricity.
The period over which the initial capital investment to build a plant is recovered.

Technology details indicate resource levels and specific technology subcategories.
Fraction of potential generation that was actually reported for a plant part. Energy generated over time period / nameplate capacity * time period (hours/years/etc.).
Capital cost (USD). Expenditures required to achieve commercial operation of the generation plant.
capex if plant could be constructed overnight (i.e., excludes construction period financing); includes on-site electrical equipment (e.g., switchyard), a nominal-distance spur line (<1 mi), and necessary upgrades at a transmission substation.
capex for retrofits if plant could be constructed overnight (i.e., excludes construction period financing); includes on-site electrical equipment (e.g., switchyard), a nominal-distance spur line (<1 mi), and necessary upgrades at a transmission substation.
Overnight capital cost includes a nominal-distance spur line (<1 mi) for all technologies, and for offshore wind, it includes export cable and construction period transit costs for a 30-km distance from shore. Project-specific costs lines that are based on distance to existing transmission are not included. This only applies to offshore wind.
Portion of all-in capital cost associated with construction period financing. This factor is applied to an overnight capital cost to represent the financing costs incurred during the construction period.
Fuel costs in USD$/MWh. NREL-derived values using heat rates.
Fuel content per unit of electricity generated.
Heat rate penalty for retrofitting. This column only has contents to retrofit technologies. It seems to be a rate between 0.35 and 0.09
Levelized cost of energy (LCOE) is a summary metric that combines the primary technology cost and performance parameters: capital expenditures, operations expenditures, and capacity factor.
Penalty for retrofitting for net output. This column only has contents to retrofit technologies. It seems to be a rate between -0.25 and -0.08
Fixed operation and maintenance expenses. Annual expenditures to operate and maintain equipment that are not incurred on a per-unit-energy basis.
Operation and maintenance costs incurred on a per-unit-energy basis.
core_nrelatb__yearly_projected_financial_cases
Annual time series of financial assumptions for each model case (model_case_nrelatb), and sub-type of technology (technology_description).

The year of the projected value.
High level description of the technology used by the generator to produce electricity.
Rate of inflation. All dollar values are given in 2021 USD, using the Consumer Price Index for All Urban Consumers for dollar year conversions where the source year dollars do not match 2021.
Also referred to as construction finance cost. Portion of all-in capital cost associated with construction period financing. It is a function of construction duration, capital fraction during construction, and interest during construction.
Calculated real interest rate.
Nominal interest rate.
Calculated real rate of return on equity.
Nomial rate of return on equity.
Combined federal and state tax rate. The R&D model_case_nrelatb holds tax and inflation rates constant at assumed long-term values: 21 percent federal tax rate, 6 percent state tax rate (though actual state tax rates vary), and 2.5 percent inflation rate excludes effects of tax credits. The Market + Policy model_case_nrelatb applies federal tax credits and expires them as consistent with existing law and guidelines.
core_nrelatb__yearly_projected_financial_cases_by_scenario
Annual time series of additional financial assumptions for NREL ATB projections that also vary by technology innovation scenario (scenario_atb), tax credit case (model_tax_credit_case_nrelatb), and cost recovery period (cost_recovery_period_years).

This table has no primary key. There are a small number of records which have nulls in the cost_recovery_period_years column. Based on NREL's documentation, this seems to indicate that those records apply to any relevant cost_recovery_period_years. If those records were non-null, the primary keys of this table would be: ['report_year', 'model_case_nrelatb', 'model_tax_credit_case_nrelatb', 'projection_year', 'technology_description', 'scenario_atb', 'cost_recovery_period_years']
