13 Cleco 2013 Transmission Construction Plan

14 2013 Transmission Construction Plan

15 Cleco 2013 Transmission Construction Plan Budgeted Projects 2 nd Cocodrie Autotransformer Cooper Capacitor Banks Strung Bus replacement at Plaisance Many Capacitor Banks 2013 2 nd Pineville Autotransformer 2014

16 2013 Transmission Construction Plan 2 nd Cocodrie 230/138 kV Autotransformer

17 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 Auto- transformer causing overloads on Coughlin to Shady Oaks 138 kV line.

18 2013 Transmission Construction Plan Cooper Capacitor Banks

19 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.

20 2013 Transmission Construction Plan Many Capacitor Bank

21 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.

22 2013 Transmission Construction Plan Coughlin to Plaisance 138 kV line Rating upgrade

23 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

24 2013 Transmission Construction Plan Pineville 230/138 kV Auto #2

25 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.

26 2013 Transmission Construction Plan Questions ?

27 Agenda Introduction Economic Planning Studies Acadiana Load Pocket Update 2013 Transmission Construction Plan Model Review 2013 SPP Model ACCC Results MISO Discussion Stakeholder Business Final Questions Adjourn

28 Remove zero Impedance ties Valley Load Change Demco Transaction Removed the Wells Reactor Messick 500 kV Tap

29 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

30 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

31 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. Model Review

36 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.

37 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.

38 2013 SPP Model ACCC Results Contingent Element: Dolet Hills to S.W. Shreveport 345 kV line IP Mansfield to Wallace Lake 138 kV line 110% Mansfield to IP Mansfield 138 kV line 105% Mitigation: Implement the Dolet Hills operating guide
