Distributed and Community Wind Energy
❖ Distributed Wind: is the use of one or a few wind turbines at homes, farms, businesses, and public facilities to off-set on-site energy consumption or small arrays placed close to loads (front-of-meter)
❖ Community Wind: medium – large wind turbines with significant local participation (like Community Solar)

Benefits of Distributed Wind Energy
❖ Least-cost renewable technology in areas with good wind resources
❖ Leverages America’s technology and manufacturing strengths Complements solar; reduces need for storage and back-up Small footprint compared to solar Strengthens the grid and promotes resilience Ramps faster than some other clean energy technologies Provides branding for environmental stewardship
More Expensive, but also More Valuable
Windfarm Turbines
❖ ~ $1,500 / kW
❖ Providing Wholesale
Power, sold at: 2 – 4¢/kWh
Distributed Turbines
❖ ~ $3-9,000 / kW
❖ Providing Retail
Power, sold at: 8 – 42¢/kWh
Wind and Solar are Complementary Energy Sources
Distributed Wind, with Less Automation, is a “Jobs Machine”

DW Potential: Comparable and Complementary to Offshore Wind
2016 & 2022 NREL Reports:
• Technical feasibility: 49.5 million residential, commercial, industrial and public sites
• Economic feasibility in 2022: 1,400 GW
• Economic feasibility in 2035: 6,000 GW
Offshore Wind serves larger coastal communities. Distributed Wind serves smaller interior, transitional and more disadvantaged communities. Both have large supply chain opportunities, but DW is far less developed.
2035 DW Potential: 1,000 GW
DWEA 2035 DW Goal: 35 GW
