Potential participants in SPP’s Markets+ day-ahead offering have endorsed another batch of tariff revisions in preparation for a March filing at FERC.

Stakeholders have discussed the likelihood that there may be two day-ahead markets in the West, CAISO’s Extended Day-ahead Market and SPP’s Markets+ and/or RTO West.

SPP met a major milestone in its Western efforts as a Markets+ committee approved the day-ahead market’s proposed governing document.

Potential SPP Markets+ participants democratically endorsed the first pieces of the day-ahead market’s tariff, acquiring a taste of the grid operator’s stakeholder process at the same time.

SPP has released the final proposal that details the proposed governance structure, market design and other key features for its Markets+ offering in the West.
