Variable Interest Entities (VIEs)	Dec. 31, 2013
Variable Interest Entities (VIEs)	Variable Interest Entities (VIEs) VIEs for which PSE&G is the Primary Beneficiary PSE&G is the primary beneficiary of and consolidates two marginally capitalized VIEs, Transition Funding and Transition Funding II, which were created for the purpose of issuing transition bonds and purchasing bond transitional property of PSE&G, which is pledged as collateral to the trustee for these bonds. PSE&G acts as the servicer for these entities to collect securitization transition charges authorized by the BPU. These funds are remitted to the trustee for Transition Funding and Transition Funding II and are used for interest and principal payments on the transition bonds and related costs. The assets and liabilities of these VIEs are presented separately on the face of the Consolidated Balance Sheets of PSEG and PSE&G because the Transition Funding and Transition Funding II assets are restricted and can only be used to settle their respective obligations. The Transition Funding and Transition Funding II creditors do not have any recourse to the general credit of PSE&G in the event the transition charges are not sufficient to cover the bond principal and interest payments of Transition Funding and Transition Funding II, respectively. PSE&G’s maximum exposure to loss is equal to its equity investment in these VIEs which was $16 million as of December 31, 2013 and 2012. PSE&G considers the risk of actual loss to be remote. PSE&G did not provide any financial support to Transition Funding or Transition Funding II in 2013 or 2012. Further, PSE&G does not have any contractual commitments or obligations to provide financial support to Transition Funding and Transition Funding II.
