1 Supporting Tennessee’s Future Energy Needs… Nuclear Generation Development & Construction Dan Pratt Manager, Pre-Construction Planning March 10, 2009

2 2  159 power distributors  62 direct serve industries  Over 8.5 million people in an 80,000 sq mile service area  Public users of land and recreational facilities  Communities with economic development assistance TVA Serves… TVA Serves…

3 3 Fossil Plants Combustion Turbines Nuclear Plants Hydroelectric Dams Pumped- Storage Green Power Fossil/Coal 64%(45%) Hydro 6%(15%) Nuclear 30%(21%) Combustion turbine and green power 1%(19%) TVA’s Diversified Generation Portfolio Generation(Capacity)

4 4 TVA Generating Facilities  11 fossil sites (59 units)  3 nuclear sites (6 units)  29 hydro sites (109 units)  11 combustion turbine sites (72 units)  1 pumped storage station  1 wind energy site  17,000 miles of transmission line

5 5  Use TVA resources to meet demand.  Increase energy conservation and demand reductions.  Provide cleaner, reliable, and still-affordable energy.  Fifty percent of generation from zero or low carbon emitting resources by 2020 For current planning horizon, when large amounts of new generation are required, this means nuclear for base load and natural gas for peaking Elements of TVA Generation Strategy

12 12 Key Insights… So Far  Competition for talent  Value of existing plant infrastructure has increased over last few years as other options have increased in price.  Local communities supportive, but worried about short term cost and services impacts to communities (ex. schools).  Identify or recruit core team early, it takes longer to build this than you think.  Changing NRC leadership

13 13 Competitive Non-Volatile Electric Price Clean Air Value Reliable Energy Supply Zero Air Emissions Protection against CO 2 risk Long-Term Costs Attractive Less Dependence on Oil and Gas High Capacity Factors ~67% of Total Cost Fixed The Benefits of New Nuclear Economic Development ~$1 Local Benefits for every $1 Spent Up to 2000 Jobs During Construction and ~500 Per Unit During Operation Nuclear Options Being Developed Because…

21 21 Cost of New Nuclear Quiz Vendor Says…. Cost of plant is: $3200/kw Utility Says… Cost of plant is: $4300/kw Which is Correct? Wall Street Says… Cost of plant is: $5500/kw All are the same… and for the same project! Overnight Plus Owners Cost EPC Only Escalated to 2017 Everything Including Interest During Construction

22 22 Major Hurdles for New Plant Construction

23 23 New Nuclear Development Approach Incremental Levels of Increased Certainty Uncertainty Today Future Uncertainty Technology Certainty (Final Design Engineering) NRC Regulatory Certainty (COL Issuance) Time Manage the uncertainty in a planned deliberate manner Project Development Certainty Financial Certainty Working In Parallel

24 24 RISK CATEGORY High Capital Costs High Financing Costs Construction: First Units Major Component Manuf. Market Competition Waste Disposal Electricity Demand Transmission Availability Water Resource Regulatory Efficiency Development (site prep/permit) Accident or Disaster Fuel Price/Supply Technology and System Construction: Later Units Low Risk High Risk Summary of Risk Ratings

25 25 Once Through Versus Closed Fuel Cycle

26 26 Where are We Headed Over Next Decade  Energy Efficiency Technologies  Grid of the Future  Nuclear Sustainability and Expansion  Cleaner Coal  Plug-in Hybrid Vehicles Accelerating Solutions

27 27 Summary Messages  Nuclear will provide clean competitively priced power –Provided risk can be managed in such a way as to keep cost of capital at reasonable levels.  Re-establishing the infrastructure to build plants will likely result in longer planning horizons (with extended timelines for cash flows) for the initial wave of new reactors.  Nuclear will remain a key generation source and expand as part of the energy mix for the foreseeable future.
