Georgia Wind Working Group

The Georgia Wind Working Group formed in 2005 through a partnership involving:

- Southern Alliance for Clean Energy

- Georgia Tech’s Strategic Energy Institute

- Georgia Environmental Facilities Authority

The Group consists of people representing utility companies, wind developers, government agencies, universities, and non-profit organizations.

Site specific data:

  • 50 m high anemometer
  • Online since June 1999 (nearly 7 years)
  • 27 m deep water,

` 60 km offshore

  • 6-minute data averages

Preliminary Findings:

Wind resource warrants further review

20 year levelized cost: 50-160 MW scale:


No “show stopper” environmental issues

Coastal community acceptance important

  • By Southern Company and Georgia Tech
  • Began July 1, 2005
  • To study viability of wind power generation off the Georgia coast

benefits of off shore wind
Benefits of Off-shore Wind

Proximity to load centers

Lower transmission constraints

Serve high cost regions

Uses indigenous energy

Avoids size limits

  • Better wind resources
  • Reduced turbulence –steadier wind
  • Higher wind = better energy production
  • Higher capacity factors –load matching
  • Minimize visual impacts with greater distances

Off-shore Wind Regulation Pending(beyond 3 nautical miles from shore)

Environmental considerations include:

Bird migratory pathways

Habitats – marine, fisheries, avian

Natural reefs and other aquatic life

  • Minerals Management Service is establishing permitting rules
  • Will require full environmental review for wind farms and cabling pathway
  • Multiple federal and state governing authorities apply



next steps for utilities and wind developers
Next Steps for Utilities andWind Developers
  • Track federal rulemaking process
  • Install a meteorological tower for wind site specific resource assessment
  • Plan wind farm projects where communities are supportive
  • Participate in competitive process for lease site

Wind Working Group

the georgia wind working group mission
The Georgia Wind Working GroupMission

Promotes the responsible development and use of wind energy by facilitating stakeholder collaborations, assisting with resource assessments, and enhancing public understanding of the benefits and impacts of wind energy.


Wind Working Group

Georgia Wind Working Group

Provides general public education

Provides technical outreach and targeted stakeholder outreach

Hosts wind workshops

Develops state specific literature

Provides presentations at key events



The Georgia Wind Working Grouplooks forward to working with theCity of Tybee Island and others to explore wind energy opportunities.
