SPP says two announcements by the Western Area Power Administration and Basin Electric Power have rounded out the group of seven western utilities that plan to pursue membership in its Western Interconnection RTO market.

Western utilities interested in SPP’s RTO West offering released a study showing the grid operator’s expansion could produce huge annual savings.

FERC denied a complaint by a pair of cooperatives that SPP “misapplied” tariff provisions during February's winter storm, costing them $79 million in revenue.

NWPP took its first steps implementing its Western Resource Adequacy Program, allowing participants to submit resource data for a “nonbinding” phase.

SPP’s Strategic Planning Committee approved a task force’s recommended framework to manage DC tie revenue-requirement recovery in the proposed RTO West.

Utilities are hoping their participation in SPP's WEIS market will be the "first step" to full RTO membership.

FERC ruled that Tri-State G&T has only partially complied with Orders 845 and approved Basin Electric Power Cooperative’s revised market-based rate tariff.

A request to waive an SPP Tariff requirement prompted a philosophical dispute between FERC Chairman Neil Chatterjee and Commissioner James Danly.

FERC opened an investigation into the justness and reasonableness of Basin Electric Power Cooperative’s 2020 rate schedule and the wholesale power contracts.
