The D.C. Circuit Court of Appeals has dismissed a review petition filed by petition by Xcel Energy and Kansas Electric Power Cooperative over FERC’s rejection of their rehearing requests related to SPP’s filed rate doctrine.

FERC rejected a pair of separate rehearing requests by SPP members related to the RTO’s assignment of network upgrade charges under tariff Attachment Z2.

SPP stakeholders once again took a crack to resolve a weighty issue in determining how futures will be considered in the RTO’s 2021 transmission plan study.

FERC denied KEPCo’s complaint that Westar Energy had twice violated its generation formula rate in assessing its own rates and federal income tax reduction.

FERC issued rulings in three SPP transmission cases, mostly siding with the RTO but rejecting its proposed changes to classifying service upgrade costs.

The Southwest Power Pool Board of Directors and Members Committee decided to take no further action on the contentious Z2 crediting issue.
