The Commission has indicated that its concerns about the potential for market power and the issue of PSCo`s access to customer load data and non-public transmission information were raised during the revisions to the agreement following a conference between the parties. The parties have structured the joint transit agreement in such a way that any PSCo BAA charging service, which undertakes to provide generation resources and whose transport provider accepts the common mail-order transport service, can become a party to the common transit agreement, FERC said. “The parties will be able to achieve substantial savings through the use of their collective resources more efficiently,” FERC said. “These savings will be passed on to their customers.” PSCo said the purpose of the joint shipping agreement was to implement a more efficient mechanism for the supply of auxiliary energy between the parties, according to the order. Each Party will continue to provide sufficient production resources to cover its own load and operating reserve needs, but it will also determine how much or little it wishes to set for joint shipping and marginal price compensation system-wide. That price is the additional cost of the megawatt of electricity closest to the economy, which can be produced by a party`s power-opening unit, FERC said. “The parties renegotiated the joint shipping agreement in order to address the Commission`s concerns that led to the rejection of the agreement last year,” FERC said. California`s ISO has paved the way for four other members to participate in the western energy investment market in 2022 and has signed an implementation agreement with Xcel Energy to allow for the membership of three more Colorado supply companies. . . .
