LG&E and KU Authorized to Exit Midwest ISO

LCG, June 2, 2006--The Kentucky Public Service Commission (PSC) on Wednesday authorized Louisville Gas & Electric Co. (LG&E) and Kentucky Utilities Co. (KU) to withdraw from the Midwest Independent System Operator (MISO), the regional electric system operator that had a service territory extending from eastern Montana through the upper Midwest - including Manitoba - and south to parts of Kentucky and Missouri.

In a two-to-one vote, the PSC ruled that the exodus from the MISO would reduce costs and maintain local control over key aspects of the utilities? operations. In dissenting, Chairman Mark David Goss stated that the withdrawal would leave Kentucky in a weak position to influence electric policy during the inevitable regionalization of transmission assets and markets.

On March 17, 2006, the Federal Energy Regulatory Commission (FERC) granted conditional approval to LG&E and KU to withdraw from the MISO. The PSC's authorization enables both utilities to proceed with the withdrawal from the MISO.

LG&E and KU plan to resume control over their transmission facilities. The utilities propose to use the Tennessee Valley Authority (TVA) to provide transmission reliability coordination services and to use the Southeast Power Pool (SPP) to address electric power marketing rules. Agreements with TVA and SPP are the subject of current, separate proceedings before the PSC.

LG&E and KU became members of the MISO in 1998. The MISO formally began commercial operations of its new, Day-Ahead and Real-Time electricity markets on April 1, 2005. Elements of the new market design include centralized, security-constrained unit commitment; security-constrained economic dispatch; locational marginal pricing (LMP); and a market for financial transmission rights (FTRs).
