PLR Contracts/Purchase of Accounts Receivable (PPL Energy Supply and PPL Electric)

 

PPL Electric holds competitive solicitations for PLR generation supply. PPL EnergyPlus has been awarded a portion of the PLR generation supply through these competitive solicitations. See Note 10 for additional information on the solicitations. PPL Electric's purchases from PPL EnergyPlus totaled $16 million and $38 million for the three and six months ended June 30, 2012 and $4 million and $10 million during the same periods in 2011. The sales and purchases are included in the Statements of Income as "Wholesale energy marketing to affiliate" by PPL Energy Supply and as "Energy purchases from affiliate" by PPL Electric.

 

Under the standard Supply Master Agreement for the solicitation process, PPL Electric requires all suppliers to post collateral once credit exposures exceed defined credit limits. PPL EnergyPlus is required to post collateral with PPL Electric when the aggregate credit exposure with respect to electricity, capacity and other related products to be delivered by PPL EnergyPlus exceeds a contractual credit limit. Based on the current credit rating and tangible net worth of PPL Energy Supply, as guarantor, PPL EnergyPlus' credit limit was $35 million at June 30, 2012. In no instance is PPL Electric required to post collateral to suppliers under these supply contracts.

Wholesale Sales and Purchases (LG&E and KU)

 

LG&E and KU jointly dispatch their generation units with the lowest cost generation used to serve their retail native load. When LG&E has excess generation capacity after serving its own retail native load and its generation cost is lower than that of KU, KU purchases electricity from LG&E. When KU has excess generation capacity after serving its own retail native load and its generation cost is lower than that of LG&E, LG&E purchases electricity from KU. These transactions are reflected in the Statements of Income as "Electric revenue from affiliate" and "Energy purchases from affiliate" and are recorded at a price equal to the seller's fuel cost. Savings realized from such intercompany transactions are shared equally between the two companies. The volume of energy each company has to sell to the other is dependent on its native load needs and its available generation.

PLR Contracts/Purchase of Accounts Receivable (PPL Energy Supply and PPL Electric)

 

PPL Electric holds competitive solicitations for PLR generation supply. PPL EnergyPlus has been awarded a portion of the PLR generation supply through these competitive solicitations. See Note 10 for additional information on the solicitations. PPL Electric's purchases from PPL EnergyPlus totaled $16 million and $38 million for the three and six months ended June 30, 2012 and $4 million and $10 million during the same periods in 2011. The sales and purchases are included in the Statements of Income as "Wholesale energy marketing to affiliate" by PPL Energy Supply and as "Energy purchases from affiliate" by PPL Electric.

 

Under the standard Supply Master Agreement for the solicitation process, PPL Electric requires all suppliers to post collateral once credit exposures exceed defined credit limits. PPL EnergyPlus is required to post collateral with PPL Electric when the aggregate credit exposure with respect to electricity, capacity and other related products to be delivered by PPL EnergyPlus exceeds a contractual credit limit. Based on the current credit rating and tangible net worth of PPL Energy Supply, as guarantor, PPL EnergyPlus' credit limit was $35 million at June 30, 2012. In no instance is PPL Electric required to post collateral to suppliers under these supply contracts.

 

PPL Electric's customers may choose an alternative supplier for their generation supply. See Note 2 for additional information regarding PPL Electric's purchases of accounts receivable from alternative suppliers, including PPL EnergyPlus.

 

At June 30, 2012, PPL Energy Supply had a net credit exposure of $38 million from PPL Electric from its commitment as a PLR supplier and from the sale of its accounts receivable to PPL Electric.

Wholesale Sales and Purchases (LG&E and KU)

 

LG&E and KU jointly dispatch their generation units with the lowest cost generation used to serve their retail native load. When LG&E has excess generation capacity after serving its own retail native load and its generation cost is lower than that of KU, KU purchases electricity from LG&E. When KU has excess generation capacity after serving its own retail native load and its generation cost is lower than that of LG&E, LG&E purchases electricity from KU. These transactions are reflected in the Statements of Income as "Electric revenue from affiliate" and "Energy purchases from affiliate" and are recorded at a price equal to the seller's fuel cost. Savings realized from such intercompany transactions are shared equally between the two companies. The volume of energy each company has to sell to the other is dependent on its native load needs and its available generation.
