Westar Energy Transmission Operations:
An Update on Regional and Local
Transmission Activity
Presented to Attendees of Westar’s Transmission Formula Rate Meeting
June 22, 2010
Transmission Formula Rate True-Up Meeting
Today’s Agenda
Transmission Formula Rate
 The
Protocols of the Formula: How They Apply to You
 A Discussion of the June 15 True-Up Calculation
An Update on Regional and Local Transmission
Activity
Attachment AQ: New Delivery Point Addition
Procedures
2
The Many Facets of Transmission…
 The Current “Hot Topics” at the Southwest
Power Pool
 Full Speed Ahead: Westar’s Transmission
Construction Status
3
The Southwest Power Pool (SPP)

Hot Topic #1: Making the System Study Process
More Efficient
 New transmission service requests
 New delivery points

Attachment AQ: The New Delivery Point Addition Procedures
 New generation interconnections


Attachment V: The New Generation Interconnection
Procedures (GIP)
Which comes first, the wind or the wires?
4
Proposed Wind Projects in SPP
5
The Southwest Power Pool (SPP)
 Hot Topic #2: Cost Allocation…Who Pays for What?
Highway/By-way Rate
FERC just approved on June 17, effective June 19,
2010
Focuses on SPP Region as a whole
Allocation according to voltage
• > or = 300 kV is spread across entire region
• > 100 kV < 300 kV is 1/3 region, 2/3 zone
• < or = 100 kV is 100% to the zone
Zonal, Regional, Base Plan Funded, Economic…oh
my!
6
The Southwest Power Pool (SPP)
 Hot Topic #3: 765 kV…Truth or Myth?
Prairie Wind Transmission
 Joint
Venture between Westar and American Electric
Power (AEP)
 First project of focus has been: Wichita-Medicine Lodge
765 kV
SPP has approved double-circuit 345 kV so far
 PWT
is working with ITC to revise KCC settlement
agreement accordingly for 345 kV
 765 kV can still become a reality
• Integrated Transmission Plan (ITP) will be issued
January 2011
• Would be operated at 345 kV for indefinite period

Construction Status Report

Westar is building more new transmission than ever



Transmission service, reliability, generator interconnections
Cost recovery via Transmission Formula Rate
Example: $200+ million vs. $10 million in earlier years

TransCanada, TransCanada, TransCanada

Other major projects:




Wichita-Reno 345 kV
Reno-Summit 345 kV
Rose Hill-Sooner 345 kV
Numerous other transmission projects…..

TransCanada is Coming!
• TransCanada will have six
pumping stations in Kansas.
• Five of those stations are in the
Westar Energy service area.
• Each station has at least two
and up to five 6500 hp motors.
• Estimated peak load at each
site will be 17-25 MW
•All locations expected to be online by the end of 2013
