FERC accepted a second compliance filing from SPP outlining its process for determining its planning reserve margin with an order that found the RTO’s response met the commission’s directives.

FERC accepted SPP’s proposed tariff revisions to implement congestion hedging improvements, ending a journey through the stakeholder process that began six years ago.

FERC denied a complaint by Missouri River Energy Services that SPP violated its tariff by failing to give the utility any firm transmission rights in every annual allocation since 2016, resulting in more than $25 million in overcharges.
