3
Annual Technology Baseline (ATB)
• Generation technology cost and performance: current data and future projections compiled into a single workbook

inputs for current and future costs and performance
o ATB presentation – includes details about the technologies and the methods used to create the projections
• Associated product: o Standard Scenarios Report – suite of electricity sector
scenarios using the ATB and other inputs that provide an outlook of how the sector might evolve over time under a range of possible conditions

Overview of Future RE Cost Projections Technology Source Rationale
Land-based and Offshore Wind Power Plants, Utility PV Plants, Residential and Commercial PV, Hydropower Plants
High, low, and median values of population from published studies that include cost projections for scenario modeling
Defining ATB High, Mid and Low cost cases as bounding scenarios to published literature provides a broad range of perspective
Concentrating Solar Power (CSP) Plants
High, low, and median values are taken from analysis of the published literature, primarily the SunShot Vision report and new technology pathway analysis in On the Path to SunShot reports.
Defining High, Mid and Low CSP cases in relation to detailed near-term analysis (2020) and relative to published literature provides a range of perspective
Geothermal Plants Site-specific nature, relative maturity of technology, and lack of existing literature survey lead to assumption of no cost reduction (High, Mid) and application of learning similar to AEO 2015 (Low).
Geothermal Vision study which will likely result in industry developed cost reduction scenarios is underway.

Land-based Wind Plant Capacity Factor: Expected Annual Average Energy Production Over Lifetime
• CF influenced by rotor swept area / generator capacity, hub height, hourly wind profile, expected downtime, energy losses within wind plant
• Majority of installed U.S. wind plants generally aligned with ATB estimates for performance in TRGs 5-7. High wind resource sites associated with TRGs 1 and 2 as well as very low wind resource sites associated with TRGs 8-10 are not as common in historic data, but the range of observed data encompasses ATB estimates.
Projection data represents expected annual CF for plants with Commercial Online Date specified by Year.
Historical data represents capacity factor for operation in 2014 for plants with Commercial Online Date specified by year.

Utility PV: CAPEX Historic Trends, Current Estimates, and Future Projections
• CAPEX estimates for 2015 reflect continued rapid decline supported by analysis of recent PPA pricing (Bolinger and Seel) for projects that will become operational in 2015 and beyond.
• CAPEX estimates should tend toward the low end of reported pricing because no regional impacts, time-lagged system prices, or spur line costs are included.
• Capacity weighted average system prices are higher than 80% of system prices in 2014 due to very large systems, with multi-year constructions schedules, installed.

Hydropower Plant Cost and Performance Projections Methodology
• Projections developed using bottom-up analysis of process and/or technology improvements to provide a range of future cost outcomes. • Low Cost: gains achievable when pushing to the limits of potential new technologies such as modularity (in
both civil structures and power train design), advanced manufacturing techniques, and materials. • Mid Cost: aggressive equipment standardization efforts, widespread implementation of value engineering
and design/construction best practices using generally conventional technology, evolution of licensing processes.
• High Cost: No change in CAPEX from 2015-2050

Changes from 2015 ATB to 2016 ATB
21
Basic Approach Remains the Same – Consistency Across Technologies Improved
• Base Year (current) cost and performance estimates from published, regularly updated sources or methods. If estimates are not based directly on market data, then they are compared with market observations as possible.
• Projections for future renewable energy cost and performance based on published literature such that: o High = current cost o Mid = median value of literature or mid-level projection from
published US-focus technology analysis (e.g., Hydropower Vision)
o Low = low bound of literature or low-level projections from published US-focus technology analysis
o Renewable energy exceptions include: – Geothermal: Vision study currently underway and will inform 2017
ATB – Solar CSP: Direct comparison not yet feasible due to differences in
storage, field sizes, turbine technologies, etc.
22
Summary of Changes from 2015 ATB to 2016 ATB
• Changes to all technologies o Updated base year from 2013 to 2014
o Updated dollar year from 2013$ to 2014$
o Updated historical data to include data reported in 2014
o Changed debt-to-equity ratio to 60/40 based on a literature review (see Mai et al., NREL/PR-6A20-65014, 2015)
o Added comparison of ATB inputs and calculated LCOE against EIA and Lazard reported values
23
Land-based & Offshore Wind
• Base year and projections still based on Wind Vision, but TRGs expanded from 5 to 10

• Solar CSP o Base Year: Default representation is 10-hours of
Thermal Energy Storage (2015 ATB had 6 and 12 hours)
o Projections: High case uses current costs o Mid case assumes steady cost reduction and that
CSP hits SunShot targets in 2030 (similar to 2015 ATB)
o Low case projection assumes that CSP hits SunShot targets in 2025 based on new technology development assumptions from On the Path to SunShot; Low case includes learning rate for post-2025 cost reductions
• Geothermal o Base Year: Supply curves updated based on
newer version of GETEM; added summary table
to illustrate range across technology and resource o Cost projections are now included—The mid cost
case keeps costs constant over time, the low cost case incorporates learning based on AEO 2015 (last year’s ATB did not include geothermal projections)
• Hydropower o Base Year: Supply curves updated with published
ORNL Hydropower Cost Report (same as Hydropower Vision); added summary table to illustrate range across technology and resource.
o Cost projections now included—Projections are from 2016 Hydropower Vision report
• Conventional o Updated conventional technologies to AEO 2016 o Updated natural gas and coal fuel costs to AEO
2016 o Added higher capacity factor coal and natural gas
entries—now coal and gas technologies have a fleet wide capacity factor entry and a “maximum” capacity factor entry
