SPP says it is pursuing inter-market optimization of energy transfers between its two Western Interconnection markets, mirroring a process it has developed in its current RTO footprint.

SPP Markets+ stakeholders unanimously approved the first version of the day-ahead market's protocols, providing a framework for market design, operations and settlements as its future participants build the systems and processes.

SPP says the development of its Markets+ day-ahead market in the West is proceeding on time and under budget, with the hard part yet to come.

The development of SPP's Markets+ has picked up the pace with stakeholders agreeing on an interim governance structure and representation on the working groups that will handle much of the effort ahead.
