1. The Windmills are Coming; “Offshore” Steven Harris Vice President EQECAT, Inc. 510.817.3105 September 19, 2011

2. © EQECAT, Inc. 2011 America’s First Offshore Wind Farm Will it be Nantucket Martha’s Vineyard Hyannis Cape Wind Project ?

3. © EQECAT, Inc. 2011 America’s First Offshore Wind Farm Or Galveston - Offshore Wind ? Wind Park Site "This is Texas. We don't have Walter Cronkite and Ted Kennedy whining about their back yards," Texas State General Land Office Jerry Patterson - Commissioner

4. © EQECAT, Inc. 2011 What are Offshore Wind Farms? Wind turbines and foundation structures Underwater high voltage cables Offshore substations and operations Onshore substations Onshore high voltage transmission

5. © EQECAT, Inc. 2011 Why are they Coming? Projected Energy Use Global energy use by fuel type 1990-2035 From US DOE Renewables will double in the next 25 years

6. © EQECAT, Inc. 2011 The United States has Ambitious regional growth targets State and Federal incentives Green energy renewable portfolio standards –Texas ~7% by 2025 –New Jersey ~20% by 2021 –California 33% by 2020 –Hawaii 40% by 2030 !!

7. © EQECAT, Inc. 2011 Offshore Wind Farm Siting and Economics Siting Requires –Good wind resource –Close to load demands –Onshore transmission capacity Total Cost of Energy –Cost of generation should be around $0.10 / kWh Most wind farms are financed and require adequate insurance

8. © EQECAT, Inc. 2011 U.S. Offshore Wind Resource and Transmission Grids to U.S. cities Cape Wind Galveston-Offshore Others?

9. © EQECAT, Inc. 2011 What are the Catastrophic exposures? Gulf of Mexico and Caribbean hurricane West Pacific Typhoon European winter windstorm Earthquake in Japan, Western US and Canada, Caribbean, South America, and others

10. © EQECAT, Inc. 2011 What is the Onshore Catastrophic Loss Experience? Typhoon Maemi Okinawa Japan 2003 (Ishihara et al., 2005a) Tropical Cyclone 03/A India 1998 (Winter-Jensen et al., 1999)

11. © EQECAT, Inc. 2011 Hurricane Risks to Offshore Farms Hurricanes have damaging wind speeds for wind farms located offshore and near the coast. Hurricanes have wind speeds more than 76 mph over widths of 60 to 120 miles Hurricanes are also accompanied by large wave loadings on structural foundations

12. © EQECAT, Inc. 2011 Wind is the Source of Power Power Generated by Turbine Wind Speed Cut-out Speed Cut-in Speed Turbine Power Operating Range Hurricane Wind and Waves are a Survival Threat to Offshore Wind Turbines Tropical and Hurricane Wind Speeds Turbines Shut-in Not Generating Power and The Peril!

13. © EQECAT, Inc. 2011 13 Technology Trend for Wind Turbines Each generation is a bigger “prototype”

14. © EQECAT, Inc. 2011 Direction in Offshore Wind Technology Capital and Energy Costs are declining –Higher capital costs than land based installations are dropping rapidly –Installed capital costs, reliability, and energy capture are all improving Technical and Infrastructure Challenges –Transmission from windy areas to the load centers are being built –Specialized vessels, purpose built portside infrastructure, robust undersea electricity transmission lines will come with development –Resource characterization is improving

15. © EQECAT, Inc. 2011 Challenges Facing Offshore Wind Deployment (Cont.) Permitting Challenges or NIMBY – Not In My Back Yard –New and untested permitting processes –Uncertainty and risk faced by potential project developers and financiers –State and federal entities have authority over siting, permitting, and installation of offshore wind facilities

16. © EQECAT, Inc. 2011 Emerging technology Risk Rapid paradigm shifts with growing technologies like wind turbines –Larger wind turbines and blades –Identical installations and new technologies –Highly correlated loss potential Limited cat loss damageability data makes engineering expertise critical to rate these exposures Potentially expensive coverage

17. © EQECAT, Inc. 2011 Onshore Insurance Structures Typical Retentions / Limits Structure Common deductible structures –2-5% for CAT –15 – 45 days Business Interruption (BI) Limits driven by lenders, corporate or partnership property program, (MFL, PML studies) CAT exposures and limits can drive the overall premium Manufacturer’s warranty period for defects (2 - 5 years) Contingent business interruption Hedges can provide some BI/CBI protection

18. © EQECAT, Inc. 2011 Insurance Questions Who will insure this new technology? How will the infrastructure be insured? –Offshore wind turbines –Offshore substations –Submarine cables –Onshore Transmission lines What will the insurance cost be?

19. © EQECAT, Inc. 2011 Business Interruption Risks Potential impact of transformers and transmission cable losses with long lead times Limited numbers of available marine vessels and cranes Damage to onshore transmission and distribution, without damage to turbines, poses contingent BI issues Rapid obsolescence of turbines results in spare parts and extended BI issues

20. © EQECAT, Inc. 2011 Future technology Insurance Issues Wind farms will go further offshore and into deeper waters New and technically challenging design concepts –Floating structures –Cable moored structures –And others
