Aquila Integration
Supply’s Synergies and Operations - Day 1 / Tier 1

Ш
            
Coal Fleet:

§
            
Leverage KCP&L’s expertise and scale in operating a large coal fleet.

§
            
Plant Condition Assessment - high level look at KCP&L/Aquila critical plant equipment to
assess key plant components and determine future actions.

§
            
Plant Practices Assessment - review and benchmark KCP&L/Aquila plant processes and
systems to incorporate best practices in new design for operations of combined facilities.

Ш
            
Gas Combustion Turbine Fleet:

§
            
Leverage Aquila’s experience operating and maintaining a geographical diverse CT fleet

§
            
Plant Condition and Plant Practices Assessments

Ш
            
Planning - Energy Resource Management, Fuels and Power Sales & Services:

§
            
Synergies in combining best practices and knowledge of two robust planning groups.

§
            
Reduced systems and related costs along with modest reductions in FTE’s for management,
reporting and delivery of each planning function.

Ш
            
Fleet Control Areas and Dispatch:

§
            
Will operate KCP&L and Aquila/SJLP as separate control areas, each with their own
dispatch functions, for some period of time after completion of acquisition.

§
            
Combined single fleet control and dispatch is longer range efficiency goal.

•
            
Negotiations to continue with 1201 as headquarters (20W9 sold)

•
            
801 Call Center will relocate to the Aquila facility in Raytown - the
best site for a consolidated Call Center (801 will be backup)

–
            
Raytown represents best choice for business continuity and overall
corporate strategy

•
            
Very convenient location

•
            
Free Parking

•
            
Flexible space for additional customer service functions

–
            
Reduces exposure of multiple sites in close proximity

–
            
Proposed East Village development makes 801 site difficult

•
            
Land price on East side of downtown is at a premium

•
            
Multimillion dollar investment required for parking

Facilities Synergies

•
            
  We (the combined utility) are on a course to realize greater than expected synergies
savings from reducing costs in operations in the resulting combined utility

•
            
  Synergies savings equates to greater investment in infrastructure and reliability in
your (area, county, city) than either utility could have achieved on its own, resulting in
improved customer satisfaction

•
            
  The result of the merger will be a stronger, more efficient regional utility that is better
able to serve you and your community

•
            
  The Metro area is being expanded and will provide 24x7 emergency coverage to
areas where it does not presently exist

•
            
  Outside the Metro area, first responders (those who take their trucks home at night)
will still be taking their trucks home so no loss of service or response time will occur

•
            
  While some facilities are being consolidated to make more efficient use of resources,
there is no elimination of field jobs detailed in the August 8th filing

•
            
  We want the integration process to be open and to keep you informed
along the way, please feel free to ask questions or raise concerns at any
point
