Three independent SPP board members providing oversight of the RTO’s Markets+ development in the West have called for policy- and decision-makers to allow the process to “follow its natural course.”

SPP assuaged potential Markets+ participants that FERC's deficiency filing and other recent developments have not hindered its commitment to Western expansion.

SPP’s Markets+ hit a snag after FERC issued a deficiency letter outlining 16 problems the RTO must address in the tariff it filed for the proposed Western day-ahead market in March.
