Conclusions ƒ

ƒ

ƒ

Under expected assumptions, the Cleco Proposal is projected to be $58 million ($41 million NPV) lower than the Existing Arrangement. Power supply costs under the Cleco Proposal are projected to vary less than under the Existing Arrangement. Savings under the Cleco Proposal are projected to be between $27 million and $93 million (90% confidence interval) on a nominal basis for the major risks evaluated.

Major Modeling Assumptions – Existing Arrangement ƒ

Special Energy rate ƒ ƒ ƒ

ƒ

Cleco natural gas generation cost reflects only existing Cleco gas-fueled units Includes CO2 allowance costs beginning 2012 Cost of market purchases based on R. W. Beck’s power market forecast

Reserve capacity ƒ ƒ

Reserves purchased to meet 13.6% reserve margin Reserve capacity price assumed to be $5/kW-mo, escalated at inflation Privileged and Confidential, Attorney Work Product

19

Major Modeling Assumptions – Cleco Proposal ƒ

Fuel charge ƒ ƒ

Average system fuel cost adjusted for 2% losses Includes CO2 allowance costs beginning 2012

Reserve capacity assumed to be provided by Cleco, other than for RPS2 ƒ COA incurs no additional DG Hunter O&M cost resulting from dispatch by Cleco ƒ

Cleco Energy Cost Model ƒ

Cleco energy costs projected based on a production cost simulation model ƒ ƒ ƒ ƒ

O&M costs of existing units from FERC Form I reports Rodemacher 3 (RPS3) assumed to be on-line 1/1/2010 Cost of RPS3 based on publicly available information and industry data Generic CT & CC units added based on a generation expansion optimization model Privileged and Confidential, Attorney Work Product
