The Delaware Public Service Commission on July 17 approved the second tranche of Delmarva Power & Light Company’s request for proposal to buy renewable energy credits, or RECs, from wind generation facilities of up to 80-megawatt capacity beginning in 2019-2020 for a 10-15 year term. The RFP is a result of a merger between Exelon Corporation and Pepco Holdings Inc. and the resulting change in control of Delmarva Power. The merger agreement contains a commitment for Delmarva Power to issue competitive solicitations to buy wind renewable energy credits in three tranches. The first tranche issued in February last year selected a bidder but did not result in a 40-megawatt contract as required, resulting in an option for bidders to propose that additional amount in the second tranche for a total of up to 80 megawatts.
