Southwest Virginia Power Station Selection of
Preferred Site

• In response to a 2004 legislative incentive,
  sponsored
• by Senator Wampler, a coalition of utilities led
  by
• Dominion has completed assessment of potential
  sites
• in Southwest Virginia.
• Exhaustive assessment of numerous sites over
• more than a year and a half
• Each site assessed on numerous criteria,
  including
• Ability to minimize environmental impact
• Proximity to fuel
• Transmission access
• Preferred site is the Virginia City site in Wise
  County
• Further development activities to be based on
  this site

3
Southwest Virginia Power Station Benefits

• 800 new jobs during construction
• Permanent employment of 75 Plant Operators
• Annual payroll of over 4 million
• Additional consumption of 2 million tons of coal
  per
• annum from local mines creating 250 mining
  jobs
• Boost to regional economy
• Substantial contribution to tax revenues
• Will provide clean, reliable economic
  electricity for Virginians

• Voluntary participation by members
• Dominion leading development activities

5
Virginia SB 651 (Wampler Amendment) Provides
Incentives

• Creates opportunity for an investor-owned energy
  distributor
• designated as a default electricity provider
  such as
• Dominion
• Facility required to use Virginia coal and be
  located within
• the Coalfield Region of Virginia
• Electrical output must be dedicated to
  Virginians and
• new generation will be needed by 2012
• Project is not exempt from applicable federal
  and state
• environmental law and regulation
• Cost recovery through default rates set by SCC

Southwest Virginia Power Station Virginia City
Site, Wise County
The Virginia City site, consisting of reclaimed
mined land, located at St. Paul, Wise County,
Virginia, has been identified as the leading
site for further development.

Southwest Virginia Power Station Generating
Technology
Leading technology is Circulating Fluidized
Bed Combustion (CFB) which has the following
advantages

• Well-established clean coal technology that has
  been
• successfully applied in the U.S. and other
  countries
• Inherently low-emissions of sulfur dioxide,
  nitrogen oxides,
• and mercury
• Air cooled condensers and dry sulfur dioxide
  control
• minimize water consumption
• Fuel flexibility including waste coal

14
Southwest Virginia Power Station CFB Clean
Coal Technology

• Limestone injection, post-combustion controls and
  fabric filters capture
• - Sulfur dioxide
• - Nitrogen oxides
• - Particulate matter
• - Mercury

15
Southwest Virginia Power Station Next Steps
Going Forward
Activities to proceed based on the Virginia City
site.

• Prepare and file environmental permit
  applications
• Develop detailed engineering design
• Complete evaluation of fuel sources
• Continue site assessment

16
Southwest Virginia Power Station Virginia City
and CFB Technology

• Virginia City best site for development
• - Scores highest on site assessment criteria
• CFB technology offers major advantages
• - Environmental performance
• - Fuel flexibility

Creating the optimal combination of location and
generating technology
