Changes from 2018 ATB to 2019 ATB
The ATB provides a transparent set of technology cost and
performance data for electric sector analysis. The update of the 2018
version of ATB to this 2019 version includes general updates to all
technologies and technology-specific updates.
General Updates to All Technologies
- The Base Year was updated from 2016 to 2017 using new market
data or analysis where applicable.
- The dollar year was updated from 2016 to 2017 with a 1.3%
- Historical data were updated to include data reported through
year end 2017.
- The R&D + Market financing case no longer includes the
effects of tariffs.
Natural Gas, Coal, Nuclear, and Biopower
- Cost and performance estimates were updated to match AEO2019 (EIA, 2019).
- Natural gas and coal fuel costs were updated to match AEO2019
- Information about current costs in published literature was
- Base Year: The base year was updated to reflect 2017
wind plant cost and performance characteristics ((Moné et al., 2017), (Stehly et al., 2018)).
- Projections: The LCOE reduction in the Mid cost case
for the Base Year to 2030 was updated based on (1) analysts' bottom-up
technology and cost modeling for median technology innovation and (2)
an LCOE percentage reduction based on learning rates from 2030 to
2050. The Low cost case was updated to reflect recent bottom-up
analysis regarding the potential of R&D to enable significant cost
reductions. More specifically, a study conducted by NREL (Dykes et al., 2017) assessed a
variety of intelligent and novel technologies that comprise
next-generation wind plant technologies in order to estimate the LCOE
of a SMART wind plant in 2030. A percentage reduction based on
learning rates was applied to reduce LCOE between 2030 and 2050.
- Base Year: The base year represents the 2017 value
from the 2018 ATB, adjusted for inflation (i.e., from 2016$ to 2017$).
- Projections: The Constant case represents LCOE
deviation from the Mid Technology Cost Scenario informed by analysts'
bottom-up technology and cost modeling. The Mid case represents a LCOE
percentage reduction estimated from BVG (Valpy
et al., 2017) and (Hundleby et
al., 2017) from the Base Year. LCOE deviation from the Mid Technology
Cost Scenario in CAPEX, O&M, or capacity factor from 2017 to 2050
was informed by analysts' bottom-up technology and cost modeling.
PV (Utility-scale, Commercial, Residential)
- Base Year: CAPEX for 2017 were updated based on new
data from Barbose and Dargouth (2018) and
Bolinger and Seel (2018);
CAPEX from 2018 were updated based on Fu et al. (2018).
- Projections: The literature survey was updated with
eight new publications, and six outdated publications were removed.
Concentrating Solar Power (CSP)
- Base Year: LCOE deviation from the Mid Technology
Cost Scenario in CAPEX, O&M, or capacity factor from 2017 to 2050
were informed by analysts' bottom-up technology and cost modeling.
- Projections: A Mid case is based on recently
published literature projections and NREL judgment of U.S. costs for
future CAPEX at 2025, 2030, 2040 and 2050 ((IRENA, 2016), (Breyer et al., 2017), (Craig, Brent, & Dinter, 2017), (Feldman, Margolis, Denholm, &
Stekli, 2016), (World Bank,
2014)). It is anticipated that CSP costs could fall by approximately
25% from the ATB CSP 2021 costs of $6,450/kWe to approximately
$4,800/kWe by 2030. From 2030 to 2050, CSP CAPEX is projected to fall
to approximately $3,380/kWe. The Low case is based on the lower bound
of the literature sample, and on the "Power to Change" Report (IRENA, 2016).
- Base Year: The Base Year was updated to 2017$ based
on the consumer price index.
- Projections: Projection of future geothermal plant
CAPEX for the Low cost case is based on the Technology Improvement
(TI) scenario from the GeoVision Study ((DOE,
2019) and (Augustine, Ho,
& Blair, 2019)). The Mid cost case is based on minimum learning
rates as implemented in AEO2015 (EIA,
2015): 10% by 2035. The Constant technology cost scenario retains all
cost and performance assumptions equivalent to the Base Year through
- The definitions of cases are unchanged from 2018.
- A simple representation of the CAPEX scenarios used in ReEDS modeling for
lithium-ion battery storage is included. A more detailed and
comprehensive update to include a broader array of storage
technologies is planned for a future ATB.
