Objectives
Provide an objective and factual framework for discussing generation technologies and investment decisions in a carbon-constrained world

Framework Overview
• Levelized cost of electricity
– Standard EPRI methodology
– 2004 costs and $’s
• Two key uncertainties
– Future “cost” of CO2
– Future price of natural gas
• Two technology portfolios
– 2010 time-period
– 2020 time-period

Future Natural Gas Prices…a Key Uncertainty
• Prices can range from the Ceiling Price (oil) to the Floor Price (coal)
• Gas prices between 2005 and 2007 will likely be set at the Ceiling Price
• Post-2007 the issue is debatable, and dependent upon outlook for LNG

Closing Thoughts
• Four key uncertainties impacting near-term decisions on new generation:
– Future cost of CO2
– Future price of natural gas
– Spent nuclear fuel storage
– CO2 capture and storage
• Extraordinary opportunity to develop and demonstrate a very low emissions portfolio of generation technologies for operation by 2020.
Together…Shaping the Future of Electricity
