Driving Forces Behind Generation Fuel Mix In the Annual Energy Outlook 26 33 rd Annual PURC Conference February 24, 26
Energy Information Administration Independent statistical agency within the Department of Energy www.eia.doe.gov Produce monthly short-term and annual long-term forecasts of U.S. and world energy markets Short Term Energy Outlook http://www.eia.doe.gov/emeu/steo/pub/contents.html Annual Energy Outlook, 26 http://www.eia.doe.gov/oiaf/aeo/index.html International Energy Outlook, 25 http://www.eia.doe.gov/oiaf/ieo/pdf/484(25).pdf Produce special analyses of emerging issues and the impacts of regulatory/legislative changes http://www.eia.doe.gov/oiaf/service_rpts.htm http://www.eia.doe.gov/oiaf/analysis.htm EIA s analyses and projections should not be seen as advocating or reflecting any position of the Department of Energy, the Administration, or any other organization.
About the Annual Energy Outlook 26 Energy markets are uncertain! AEO26 based on current rules and regulations as of October 25 AEO26 includes over 35 cases, including: Three alternative economic growth cases Three alternative oil/gas price cases Three coal price cases Dozens of alternative technology cases Several regulatory sensitivity cases Across cases: 23 world oil price ranges from $28 to $9 per barrel 23 wellhead natural gas price ranges $4.97 to $7.71 per thousand cubic feet All cases should be considered All forecasts are wrong!
Extension to 23 Key Changes to AEO26 Incorporation of nitrogen oxide (NO x ) and sulfur dioxide (SO 2 ) emission regulations in the Clean Air Interstate Rule (CAIR) Incorporation of mercury regulations of Clean Air Mercury Rule (CAMR) Representation of standards and tax incentives in the Energy Policy Act of 25 Higher world oil prices Higher U.S. natural gas prices Slower electricity demand growth
Factors in Fuel / Technology Selection Demand Growth and Load characteristics Existing technology mix New technology cost and performance characteristics Fuel prices Interest rates / cost of capital Tax and other policy incentives Environmental regulations Regulatory structure

Uncertainty All forecasts are wrong - only the publication frequency varies! Why might our reference case be wrong: More/less rapid changes in the cost and/or performance of generating technologies Different fuel costs Changes in environmental regulations or other policies Changes in consumer preferences Annual Energy Outlook includes a wide array of scenarios which consider some of these uncertainties
