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.
