Key Findings • Annual wind additions were modest in 2013, but signals point to
more-robust growth in 2014/15 • Notwithstanding 2013, wind has been a significant source of new
generation in the U.S. since 2007 • Supply chain has been under duress, but domestic manufacturing
content for nacelle assembly, blades, and towers is strong • Turbine scaling is boosting expected wind project performance,
while the installed cost of wind is on the decline • Trends are enabling very aggressive wind power pricing and solid
economics in many regions despite low natural gas prices • Growth after 2015 remains uncertain, dictated in part by future
natural gas prices, fossil plant retirements, and policy decisions, though technological advancements and recent declines in the price of wind energy have boosted future growth prospects

No Commercial Offshore Turbines Commissioned in the U.S., but 15 Projects Totaling 5.1 GW Are Somewhat More Advanced in Development
• Two projects have power purchase agreements (PPAs):
• Cape Wind (MA) • Deepwater Wind (RI)
• Three demonstration projects selected for deployment by DOE
• Scale model of floating turbine deployed in ME in June 2013
• MD established offshore wind set-aside within state’s RPS
• Fishermen (NJ), Baryonyx (TX) Statoil (ME) faced set-backs

Interconnection Queues Demonstrate that a Substantial Amount of Wind Is Under Consideration
Wind represented ~36% of capacity in sampled 37 queues
But… absolute amount of wind (and coal & nuclear) in sampled queues has declined in recent years whereas natural gas and solar capacity has increased
Not all of this capacity will be built….
• AWEA reports >13 GW of capacity under construction after 1Q2014

Manufacturing Supply Chain Experienced Substantial Growing Pains
Note: map is not intended to be exhaustive
• Over last decade, foreign and domestic manufacturers have localized and expanded U.S. manufacturing presence
• 5 of 10 turbine OEMs with largest share of U.S. market through 2013 had manufacturing facilities in the U.S. at the end of 2013, compared to one in 2004
• Uncertain demand and growing global competition have created strain: general trend in 2013 was towards reduced workforce or closed facilities
• Only one facility opened in 2013, with a larger number closed or dormant
• Wind related jobs declined from 80,700 in 2012 to 50,500 in 2013

Sharp Decline in Wind-Related Imports and Stable Exports in 2013
• Figure only includes selected, tracked trade categories; misses other wind-related imports • See full report for the many assumptions used to generate this figure
* estimated imports
U.S. is a net importer of wind equipment Exports of wind-powered generating sets increased modestly in 2013 to $421 billion; no ability to track other wind-specific exports, but total tower exports equalled $129 million
WIND AND WATER POWER PROGRAM
Tracked Wind Equipment Imports in 2013 Mostly from Asia, the Americas, and Europe
Note: Tracked wind-specific equipment includes: wind-powered generating sets, towers, hubs and blades, wind generators and parts. 22
WIND AND WATER POWER PROGRAM
23
Source Markets for Imports Vary Over Time, and By Type of Wind Equipment
• Considering total 2013 imports in these selected trade categories: 45% from Asia, 38% Americas, 16% from Europe
• Majority of wind-powered generating sets from home countries of OEMs, but share from Europe in recent decline
• Majority of tower imports from Asia (less from North America), but tariff measures largely stopped imports from China and Vietnam in 2013
• Most imports of blades & hubs from Brazil and China in 2013
• Globally diverse sourcing strategy for generators & parts, with increase from Asia in 2013
WIND AND WATER POWER PROGRAM
24
Despite Supply Chain Challenges, a Growing Amount of the Equipment Used in U.S. Wind Projects Has Been Sourced Domestically since 2006-07
Because imports occur in untracked trade categories, including many nacelle internals, overall import (domestic) content is higher (lower) than suggested here: in 2012, overall domestic content estimated at ~40%
When presented as a fraction of equipment-related turbine costs, the combined import share of tracked wind equipment (i.e., blades, towers, generators, gearboxes, and wind-powered generating sets) has declined from nearly 80% in 2006-2007 to ~30% in 2012-2013. See report for the assumptions used to generate these figures Approximate Domestic Content of Major Components in 2012-2013

Wind Curtailment Is Substantial, but Has Generally Declined in Recent Years
In areas where curtailment has been particularly problematic in the past – principally in Texas – steps taken to address the issue have born fruit
Estimated Wind Curtailment (GWh and % of potential wind generation)
MISO, ERCOT, NYISO, and PJM track both forced and economic curtailment, while BPA, NSP, PSCo, and SPS likely only capture forced curtailment

Wind Power Price Trends
WIND AND WATER POWER PROGRAM

Sample of Wind Power Prices • Berkeley Lab collects data on historical wind power sales
prices, and long-term PPA prices
• PPA sample includes 343 contracts totaling 29,632 MW from projects built from 1998-2013, or planned for installation in 2014 or 2015
• Prices reflect the bundled price of electricity and RECs as sold by the project owner under a power purchase agreement – Dataset excludes merchant plants and projects that sell renewable
energy certificates (RECs) separately
– Prices reflect receipt of state and federal incentives (e.g., the PTC or Treasury grant), as well as various local policy and market influences; as a result, prices do not reflect wind energy generation costs

Policy and Market Drivers
WIND AND WATER POWER PROGRAM
57
Availability of Federal Incentives for Wind Projects Built in the Near Term Has Helped Restart the Domestic Market, but Policy Uncertainty Persists • Near-term availability of the PTC/ITC for those projects that reached the
“under construction” milestone by the end of 2013 has helped restart the domestic market and should enable solid growth at least through 2015
• Little action in 2013 on what are among the wind industry’s two highest priorities: a longer-term extension of federal tax incentives and passage of a federal renewable or clean energy portfolio standard
• Prospective impacts of more-stringent EPA environmental regulations, including those related to power-sector carbon emissions, may create new markets for wind energy
WIND AND WATER POWER PROGRAM
58
State Policies Help Direct the Location and Amount of Wind Development, but Current Policies Cannot Support Continued Growth at Recent Levels
• 29 states and D.C. have mandatory RPS
• State RPS’ can support ~3-4 GW/yr of renewable energy additions on average through 2025 (less for wind specifically)

Solid Progress on Overcoming Transmission Barriers Continued • 3,500 circuit miles of new transmission built in 2013; completion of the
Competitive Renewable Energy Zones project in Texas • EEI has identified over 170 transmission projects in development, 76% of
which would – at least in part – support the integration of renewable energy • AWEA has identified 15 near-term transmission projects that – if all were
completed – could carry almost 60 GW of additional wind power capacity • FERC continued to implement
Order 1000, requiring public utility transmission providers to improve planning processes and determine a cost allocation methodology for new transmission investments

System Operators Are Implementing Methods to Accommodate Increased Penetrations of Wind
Notes: Because methods vary and a consistent set of operational impacts has not been included in each study, results from the different analyses of integration costs are not fully comparable. There has been some recent literature questioning the methods used to estimate wind integration costs and the ability to disentangle those costs explicitly, while also highlighting the fact that other generating options also impose integration challenges and costs to electricity systems
Integrating wind energy into power systems is manageable, but not free of additional costs

Conclusions • Annual wind additions were modest in 2013, but signals point to
more-robust growth in 2014/15 • Notwithstanding 2013, wind has been a significant source of new
generation in the U.S. since 2007 • Supply chain has been under duress, but domestic manufacturing
content for nacelle assembly, blades, and towers is strong • Turbine scaling is boosting expected wind project performance,
while the installed cost of wind is on the decline • Trends are enabling very aggressive wind power pricing and solid
economics in many regions despite low natural gas prices • Growth after 2015 remains uncertain, dictated in part by future
natural gas prices, fossil plant retirements, and policy decisions, though technological advancements and recent declines in the price of wind energy have boosted future growth prospects
