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.

Former SPP COO Carl Monroe's decades of outreach to Western Interconnection entities are evident in the RTO's various markets and service offerings in the West.

SPP says it has cleared its backlog of generator interconnection requests that date back to 2018, paving the way for a transition to its “first-in-the-country” Consolidated Planning Process.

SPP’s Board of Directors has approved a pair of contentious measures that were put aside during its August quarterly meeting, a tariff change to integrate and operate high-impact large loads and a revised cost estimate for a 765-kV transmission project.

SPP and its members are working together on a draft 765-kV transmission overlay as part of its 2025 Integrated Transmission Planning assessment that will dwarf 2024's record study.

SPP’s Market Monitoring Unit says in its latest report that the Western Energy Imbalance Service market’s average load energy prices rose “significantly” during the spring quarter of 2025.

Vice Chair Ray Hepper has been serving as the SPP Board of Directors' chair in place of John Cupparo, who is stepping away from the position's time requirements.

SPP stakeholders have approved a revised version of the grid operator’s fast-track study to integrate high-impact large loads during a special virtual meeting of the Markets and Operations Policy Committee.

FERC has approved SPP’s tariff revision that establishes separate planning reserve margins for the summer and winter seasons, saying it will provide “more granularity” by recognizing the reliability differences between the two seasons.
