SINGAPORE (Standard&Poor's) Dec. 12, 2007--Standard&Poor's Ratings Services said today that its 'AA' corporate credit ratings on Singapore Power Ltd. (SingPower) and on its 100% owned subsidiary SP PowerAssets Ltd. (SPPA) remain on CreditWatch with negative implications, where they were initially placed on March 30, 2007, following the decision by SingPower's subsidiary, SP AusNet Group (A/Watch Neg/--), to not proceed with the purchase of Alinta Ltd.' s (BBB/Watch Neg/--) assets from SingPower. It is likely that SingPower may continue to hold the Alinta-related assets and may bear the entire burden of financing this acquisition, which potentially places further downward pressure on its ratings. The CreditWatch on SingPower and SPPA will be resolved after clarification of the financing
