SPP General Counsel Paul Suskie laid out the implications of FERC’s reversal of a waiver it had previously issued to the RTO on Tariff Attachment Z2.

FERC reversed a waiver it had issued to SPP on Attachment Z2 of its Tariff and directed it to provide refunds of credit payment obligations, with interest.

FERC on Tuesday rejected separate complaints by the Nebraska Public Power District and Xcel Energy over billed charges under Attachment Z2 of SPP's Tariff.

FERC granted the request by SPP to waive its one-year resettlement window so that the RTO can correctly bill transmission-upgrade customers.

The Dec. 21 FERC order requiring SPP to help fast-start resources set LMPs added one more to-do for the RTO in what is shaping up to be a busy 2018.

A mismatch between posted Z2 reports and invoices sent this month forced the RTO to email members to “dispel any confusion that may have resulted.”

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

SPP’s Board of Directors approved a cleanup of Tariff language that just may have put the RTO’s troublesome Z2 process in the rearview mirror.

KCP&L is fulfilling its promise to take legal action against SPP for how the RTO allocates costs to customers after a new transmission owner joins a zone.

The SPP Board of Directors and Members Committee approved MOPC's decision to let the Z2, Export Pricing and Gas-Electric Coordination task forces expire.
