A number of protests of the resubmittal were filed at FERC including Colorado Springs Utilities and Platte River Power Authority. SPP resubmitted the proposal in early October.
The Commission in its Dec. 23 order found that the WEIS Market “will yield diverse benefits to the participating utilities and customers in the Western Interconnection, and that SPP has both addressed the concerns presented by the Commission in the July Order and demonstrated that its proposal presents a just and reasonable regional solution.”
Expected benefits described in the order include having a broader pool of resources available to serve load, which allows participants to meet their energy imbalance needs at lower cost; improved reliability; and better integration and management of higher levels of variable energy resources.
The protestors were aligned in their concerns on most issues.
