Improve Fleet Efficiency

[Includes a bar graph entitled "Production Cost" which displays the planned
production cost for years 2000 through 2004, compares actual costs for years
2000 & 2001, and compares those costs to industry median and top quartile costs.
Production cost ($/MWh) is on the vertical axis, years and refueling outages by
year are on the horizontal axis, and the graph represents the following data:]

[Next to the graph appears the following text:]

The fleet has competitive operating costs
   o Fleet aggregate average production cost is in industry top quartile
Fleet has captured merger synergies
   o Staffing reductions
   o Supply savings





[Includes a waterfall chart entitled "All-in Costs at 95% Capacity Factor" which
displays the cents/kWh cost of generating electricity and shows the 2001 actual
costs and the expected changes in cost components which lead to electricity cost
targets for 2002 and 2003:

o        2001 actual all-in cost = 2.04 cents/kWh
o        5 additional refueling outages in 2002 will add .06 cents/kWh
o        2002 all-in cost goal = 2.10 cents/kWh
o        Increased pensions and benefits will add .02 cents/kWh to all-in cost
o        Increased fuel costs will add .02 cents/kWh to all-in cost
o        3 fewer outages will save .03 cents/kWh
o        Additional output will lower all-in cost by .05 cents/kWh
o        Lower operating and maintenance costs will save .06 cents/kWh
o        2003 all-in cost goal = 2.00 cents/kWh

The following text appears next to the graph:]

Target-2(cent)/kWh all-in cost by 2003
   o Competitive with any other power supply; always dispatch
Manage O&M costs
   o Achieve staffing reduction targets
    - Benchmark to best sites
    - Support single-site competitiveness
   o Site-by-site cost comparison
   o Synergies/efficiencies
Manage fuel costs
   o Changing supply market
Manage non-production costs
   o Taxes, pensions and benefits
   o Corporate overheads
