SERC Generation Development Survey

• Fifth annual survey
• Survey request sent in late January
• Information requested from Transmission Providers
• All results received by early March

Leading the Industry!!!

SERC Generation Development Survey

• Collects 10 years of planned generation
  development
• Categorizes facilities by interconnection status
• Interconnection service requested
• Interconnection agreement signed
• Sub-categories indicate the amount of generation
  designated as a network resource
• Reports aggregate, not plant specific, generation
  plant capabilities
• Final results reported on Regional and
  subregional basis

SERC Generation Development Survey

• Total projected generation capacity for Summer
  03 (222,960 MW) exceeds projected Summer 03
  load (157,941 MW) by 65,000 MW
• Total connected generation capacity at the end of
  last year exceeds projections for SERC Regional
  load in 2012
• Projected capacity additions indicate sufficient
  generating resources over the long-term planning
  horizon

17
SERC Generation Development Survey

• SERC Generation Development survey accurately
  projects actual generation development for the
  following year
• Survey reflects recent decline in proposed
  generation capacity additions
• Survey projects generation capacity additions of
  73,000 MW over the next 10 years
• Projected capacity additions for the same period
  have declined by 61 in the past year
• Network resource additions continue to be a small
  percentage of the projected capacity additions in
  the Region

SERC Transmission Development Survey

• Second annual survey
• Survey request sent in late January
• Information requested from Transmission Providers
• All results received by early March

Leading the Industry!!!
19
SERC Transmission Development Survey

• Requests total planned transmission expenditures
• 5 years of cost data
• 100 kV and above
• Requests aggregate data for transmission
  projects, only
• New lines
• New substations
• Line rebuilds
• Substation rebuilds
• Line reconductoring projects
• Excludes distribution station costs
• Results available on a Regional and subregional
  basis

SERC Transmission Development Survey

• Actual spending in 2002 fell short of projected
  spending acquired from last years survey
• Cancellation of generation may have contributed
  to a portion of the decline
• Shortfall was minimal, indicating real spending
  has been occurring on the SERC transmission
  systems
• Projected spending for next five years (beginning
  in 2003) is slightly below five-year projected
  spending from 2002
• 2003 survey projected spending correlates well
  with 2002 actual spending
