Electricity Demand

• The EIA 2005 Annual Energy Outlook was used to
  determine growth in electricity demand between
  2002 and 2018 by fuel type and electricity market
  region.
• Note Alaska not included in this presentation.

3
Number of New Units

• Existing units were grown to 0.85 CF.
• States/tribes identified units under construction
  or in permitting.
• All demand for gas-fired generation was accounted
  for by existing units and those identified as
  being built or permitted.
• The remaining demand for coal-fired generation
  was assumed to be produced by eighteen (18)
  500-MW units.

4
Location of New Coal Units

• It is assumed that no new coal units will be
  built in CA, OR, WA, and SD.
• 3 of the 18 units are needed in the Dakotas to
  support the market they serve.
• Hence, 3 new units placed in ND.
• The other 15 are distributed among the remaining
  states in proportion to their existing imminent
  capacity.

5
Location of New Coal Units

• A states new units were assigned to counties
  based on
• Announcements of plans to build and
• Existing coal units and infrastructure
• Emissions are assumed to occur in the centroid of
  the county.

6
Quantity of New Unit Emissions

• BACT rates for SO2 and NOx from 12 Western
  facilities were examined to determine that a new
  500 MW coal unit would emit 1,675 tons of SO2 and
  1,675 tons of NOx annually.
