Overview
The Annual Technology Baseline (ATB) is the National Renewable Energy Laboratory's authoritative, annually updated projection of cost and performance for US electricity generation and storage technologies. It is the de-facto reference for capacity-expansion and production-cost modelling in North America, and a common benchmark elsewhere.
This dataset surfaces the 2024 ATB workbook (v3) summary tables: trajectories from 2022 to 2050 under three cost cases —
- Advanced — aggressive technology innovation
- Moderate — the ATB's central case
- Conservative — minimal technology advancement
What's included
Seven headline metrics, each across the full technology/class matrix (~175 series):
- CAPEX (USD/kW) and levelized cost of energy (USD/MWh)
- Capacity factor, by resource class
- Fixed and variable O&M (USD/kW-yr, USD/MWh)
- Fuel cost (USD/MMBtu) and fixed charge rate
Technologies span land-based, offshore and distributed wind, utility and distributed PV, CSP, geothermal, hydropower, pumped storage, nuclear (large and SMR), biopower, coal and natural gas (including CCS variants and retrofits), batteries (utility, commercial, residential) and PV-plus-battery hybrids — each broken into the ATB's resource classes.
All values are in 2022 US dollars, R&D financial case. The ATB's class structure can be hard to navigate in the workbook — the Data Explorer tab makes every technology/class searchable and chartable side by side.
