SPP named Tim Vigil, chief member relations and strategy officer for Pacific Northwest Generating Cooperative, as director of the Market Monitoring Unit’s office dedicated to Markets+.

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.

SPP stakeholders resoundingly rejected a proposed tariff change to integrate large loads, pushing back against what some say is a rushed process outside of the normal stakeholder structure.

FERC accepted SPP's tariff revisions to its Western Energy Imbalance Service market that allow market holds for reliability-based concerns when requested by a balancing authority.

With winter storms, load sheds and tight operating conditions, 2025 has turned out to be “quite a challenging year” for SPP.

FERC accepted SPP’s proposed tariff revisions to incorporate a mark-to-auction collateral requirement for its transmission congestion rights market but did not terminate a show-cause proceeding.
