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

capex_grid_connection_per_kw

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.

levelized_cost_of_energy_per_mwh

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.

net_output_penalty

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

opex_fixed_per_kw

Fixed operation and maintenance expenses. Annual expenditures to operate and maintain equipment that are not incurred on a per-unit-energy basis.

opex_variable_per_mwh

Operation and maintenance costs incurred on a per-unit-energy basis.

core_nrelatb__yearly_projected_financial_cases

package: pudl

The Market + Policy model_case_nrelatb applies federal tax credits and expires them as consistent with existing law and guidelines.

Primary key:

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']
