16 Wind Resources Georgia s Offshore Wind Resources 16

17 Wind Resources Recent Studies Focusing on Georgia s Offshore Wind Potential: Southern Winds 2007: Georgia Tech and Southern Company Georgia s Offshore Renewable Energy Potential : 2010: Georgia Tech Siting Analysis for Potential Near-Term Offshore Wind Development : Phase 2A of the Southeast Ocean-Based Renewable Energy Infrastructure Project 2011: Geo-Marine, Inc. Building an Infrastructure for Ocean Based Renewable Energy in the Southeast U.S. Phase 2B Southeast Mesoscale Study. 2011: AWS Truepower Building an Infrastructure for Ocean Based Renewable Energy in the Southeast U.S. Phase 2C Offshore Wind Energy Transmission Study 2011: EnerNex 17

19 Wind Resources Georgia Siting Analysis (Phase 2A) Three study blocks off the coast of Georgia that meet the lowest intrusiveness criteria 300 MW minimum size of study block area Determined by overlay analysis of numerous GIS datasets Data includes: Wildlife and fish habitat Shipping lanes Military use areas Pipelines Etc. 19

20 Wind Resources How Much Power Potential Does This Represent in Georgia? Source: AWS Truepower, Phase 2B study 20

21 Wind Resources Challenges to Offshore Wind Expense Development costs of % more than onshore wind. Long permitting timeline and large number of agencies involved creates regulatory uncertainty. Lack of development infrastructure, including supply chains, in the U.S., compared to parts of Europe. Competing ocean uses: Fishing Tourism Military Other environmental concerns. Financing Public acceptance 21

22 Wind Resources Benefits Beyond Clean Energy Economic Development Currently direct and indirect jobs in Georgia due to the wind supply chain (AWEA) ZF Group gearbox facility in Gainesville. Estimated 85,000 Americans employed in wind related industries (AWEA). Supply Chain: Estimated 8,000 parts in a turbine. Education Wind for Schools Source: AWEA 22
