• Power generation usage 4,106 BCF or 19.1
• of total natural gas consumption
• By 2010
• Total natural gas demand 24,698 BCF
• Power generation usage 6,530 BCF or 26.4

• Electric Generators have conflicting scheduling
  requirements.
• Over a 24 hour period, gas fired generators must
  schedule gas for electric generation prior to
  being scheduled on the electric side, to generate
  electricity.
• The energy day should start in a non-peak period.
• The gas day starts in the middle of the morning
  peak on the East Coast and the Midwest.

Energy Day - Conclusion

• Develop a standardized Energy Day
• Begin the Energy Day at an off-peak period 12
  midnight to 12 midnight based on Central Standard
  Time
• Benefits
• Enhances communication between the gas and
  electric industries
• Fosters the coordination of scheduling
• Allows both industries to more closely match fuel
