SPP’s Board of Directors approved the grid operator’s “historic” $7.65 billion package of transmission projects, but delayed a decision on a need date for two of the projects after stakeholders pushed back on staff’s staging recommendations.

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.

SPP stakeholders have endorsed what one member called an “historic” transmission plan that will eclipse any previous portfolio by a factor of five with a projected cost of $7.65 billion.

SPP is considering a 765-kV solution and several 500-kV proposals in its Permian Basin footprint in Texas and New Mexico as it dabbles with extra-high-voltage transmission lines.

SPP’s Markets and Operations Policy Committee endorsed recommended revision requests from two stakeholder groups as part of the RTO’s effort to strengthen resource adequacy.

SPP filed bylaw amendments at FERC to place seven Western entities under its tariff that, if approved, will make the RTO the first grid operator with markets in both major interconnections.

SPP publicly alerted stakeholders it failed to conduct a tariff-required analysis of several GI queue study clusters during their effort to reduce the backlog of GI requests dating back to 2017.

SPP stakeholders have approved congestion-hedging implementation policies six years in the making that had some likening it to Groundhog Day.

SPP stakeholders approved two revision requests that set resource adequacy policies, but not before rejecting a compromise position offered by two stakeholder groups.
