Golden Spread Electric Cooperative will again appeal a stakeholder group’s rejection of a proposed tariff change that would pre-emptively determine the amount of load SPP's system can handle without requiring additional network upgrades.

FERC directed SPP to submit a compliance filing for its proposal to unwind credit payment obligations assessed under Attachment Z2 of the SPP tariff for transmission service taken from 2008 to 2016.

SPP's Markets and Operations Policy Committee has endorsed the last of 21 recommendations made by a task force that reviewed the RTO's transmission and market operations last decade.

SPP says it is devoting significant resources to finally resolve Attachment Z2, a bone of contention among SPP stakeholders since 2016 -- by the end of this decade.

The 8th U.S. Circuit Court of Appeals denied review petitions by several SPP members over FERC's rejection of generators’ rehearing requests seeking compensation under tariff Attachment Z2.

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 four separate rehearing requests related to SPP’s revenue credits under Attachment Z of its tariff.

FERC partially granted three complaints filed by members against SPP related to its revenue crediting process under Attachment Z2 of its tariff.

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.

The D.C. Circuit backed FERC's reversal of a waiver over SPP transmission upgrade costs, even though it resulted in a “free pass” for some system users.
