2017 ATB

For each electricity generation technology in the ATB, this website provides:

  • Capital expenditures (CAPEX): the definition of CAPEX used in the ATB and the historical trends, current estimates, and future projections of CAPEX used in the ATB
  • Operations and maintenance (O&M) costs: the definition of O&M and the current estimates and future projections of O&M used in the ATB
  • Capacity factor (CF): the definition of CF and the historical trends, current estimates, and future projections of CF used in the ATB
  • Future cost and performance methods: an outline of the methodology used to make the projections of future cost and performance in the ATB for High, Mid, and Low cost cases
  • Levelized cost of energy (LCOE): metric that combines CAPEX, O&M, CF, and projections for High-, Mid-, Low-cost cases for illustration of the combined effect of the primary cost and performance components and discussion of technology advances that yield future projections.

Electricity generation technologies are selected on the left side of the screen, and the topics highlighted above can be selected using the drop-down menu at the top-right of the screen.

Guidelines for using and interpreting ATB content are provided. LCOE captures the energy component of electric system planning and operation, but the electric system also requires capacity and flexibility services to operate reliably. These services are represented in electric sector models such as the Regional Energy Deployment Systems (ReEDS) model and corresponding analysis results such as the NREL Standard Scenarios.

The NREL Standard Scenarios, a companion product to the ATB, provides a suite of electric sector scenarios and associated assumptions—including technology cost and performance assumptions from the ATB.

ATB data sources and references are also provided for each technology. All dollar values are presented in 2015 U.S. dollars, unless noted otherwise.
