2013 Transmission Construction Plan
Cleco 2013 Transmission Construction Plan
2013
Budgeted Projects
• 2nd Cocodrie Autotransformer
• Cooper Capacitor Banks
• Strung Bus replacement at Plaisance
• Many Capacitor Banks
2014
• 2nd Pineville Autotransformer
2013 Transmission Construction Plan
2nd Cocodrie 230/138 kV Autotransformer
2013 Transmission Construction Plan
Project:
Second 230/138KV Autotransformer at Cocodrie
Substation
In-service Date:
April 2013
Transmission Project Justification:
•This project relieves the potential overload on the existing Cocodrie
Autotransformer FTLO Cocodrie to Ville Platte 230 kV line. This
project also eliminates the contingency of the existing Autotransformer causing overloads on Coughlin to Shady Oaks 138 kV
line.
2013 Transmission Construction Plan
Cooper Capacitor Banks
2013 Transmission Construction Plan
Project:
Cooper capacitor 2- 36 MVAR bank addition
In-service Date:
March 2013
Transmission Project Justification:
•This project was approved to allow for maintenance on the Cooper to
Leesville and Cooper to Derrider double circuit 138 kV lines and
improve the voltage in the Leesville/ Derrider areas. Operationally
there is no way to get an outage on these lines with out risking low
voltage for the loss of the Cooper to Penton 230 kV line.
2013 Transmission Construction Plan
Many Capacitor Bank
2013 Transmission Construction Plan
Project:
Many capacitor 23.4 MVAR bank addition
In-service Date:
June 2013
Transmission Project Justification:
•This project was approved to mitigate potential low voltages seen in
the powerflow models during summer peak conditions at Many 138
kV Substation for the loss of the Many to Fisher 138 kV line.
2013 Transmission Construction Plan
Coughlin to Plaisance 138 kV line Rating upgrade
2013 Transmission Construction Plan
Project:
Transmission element replacements on Plaisance –
Coughlin 138KV transmission line (Replace Strung bus
at Plaisance)
In-service Date:
March 2013
Transmission Project Justification:
•This project increases the Plaisance to Coughlin 138 kV line rating to
prevent overloads FTLO Cocodrie to Ville Platte 230 kV line.
•Increase the rating to 360 MVA
2013 Transmission Construction Plan
Pineville 230/138 kV Auto #2
2013 Transmission Construction Plan
Project:
Pineville 230/138 kV Auto #2
In-service Date:
June 2014
Transmission Project Justification:
•This project prevents pre-contingent load shed as a result of a
extended outage of either the Pineville or Twin Bridges 230/138 kV
Autotransformers. Operationally with one of these transformers out
of service loss of the other autotransformer would lead to low voltage
in the Pineville/Alexandria areas and thermal overloads on lines in
that region.

Remove zero Impedance ties
Valley Load Change
Demco Transaction
Removed the Wells Reactor
Messick 500 kV Tap
Model Review
Removed Zero Impedance Ties
• SPP wants to remove the zero impedance ties from the Powerflow
models.
• Changed the way we model load connected to external systems
which traditionally modeled with a Cleco load on a Cleco bus.
• Now the load ID is Cleco however it is connected to an external bus
Valley Load Change
• Changed the Valley load to be AEP load instead of Cleco load.
• Set up a transaction in the powerflow models for the remainder of
the time Cleco is serving the load.
Model Review
Demco Transaction
• Set up a transaction from Cleco to Lagn to serve the Demco load
starting in 2014.
Removed Wells Reactor
• With the completion of the ALP project and the addition of the
second Wells 500/230 kV Autotransformer the Wells reactor was
no longer needed to restrict flow into the ALP.
• Cleco went through the approval processes within SPP to remove
the Wells SPS and removed the reactor from the models.
• Reactors remain at wells however are not connected.
Model Review
Messick 500 kV Tap
• The final SPP models have the Mount Olive to Hartsburg 500 kV
line tapped near Messick substation in the 2019 and 2024 models.
However the models do not include a 500/230 kV Auto.
• This project is currently being jointly studied by AEP, Cleco,
Entergy, SPP and MISO?
• No firm commitment to build has been established at this point.

•
2013 (Spring, Summer Shoulder, Summer,
Fall, Winter)
•
2014(Spring, Low load, Summer Shoulder,
Summer, Fall, Winter)
•

2024 (Summer, Winter)
2013 SPP Model ACCC Results
• International Paper to Mansfield 138kV transmission
line thermal overload
• Powerflow models: 2013, 2014 and 2015 Summer and
2014 Winter peak models
• Contingency: Dolet Hills to S.W.Shreveport 345 kV
transmission tie line
• Resolution: The Dolet Hills Operating Guide addresses
this outage and resulting overload. The Dolet Hills Plant
would be reduced to a level such that the flow on the IP
to Mansfield 138 kV transmission line is within limits.
2013 SPP Model ACCC Results
• International Paper to Wallace Lake 138kV transmission
tie line thermal overload
• Powerflow models: 2013, 2014 and 2015 Summer peak
models
• Contingency: Dolet Hills to S.W.Shreveport 345 kV
transmission tie line
• Resolution: The Dolet Hills Operating Guide addresses
this outage and resulting overload. The Dolet Hills Plant
would be reduced to a level such that the flow on the IP
to Mansfield 138 kV transmission line is within limits.
2013 SPP Model ACCC Results
IP Mansfield to Wallace
Lake 138 kV line 110%
Mansfield to IP
Mansfield 138 kV
line 105%
Contingent Element:
Dolet Hills to S.W. Shreveport 345 kV line
Mitigation: Implement the Dolet Hills
operating guide
2013 SPP Model ACCC Results
• Champagne to Plaisance 138 kV transmission line
thermal overload
• Powerflow models: 2014 (Fall, Spring, Summer, Summer
Shoulder, Winter), 2015 Winter, 2019 Winter, 2024
(Summer and Winter) models
• Contingency: Cocodrie to Ville Platte 230 kV
transmission line
• Resolution: The terminal equipment at Champagne was
upgraded to 287 MVA which eliminates this overload
condition.
2013 SPP Model ACCC Results
Contingent Element:
Cocodrie to Ville Platte
230 kV line
Mitigation: Line rating already
upgraded to 287 MVA
Champagne to Plaisance 138
kV line 121% (231 MVA)
