BPA would have to strike several types of agreements, many of which are complex and could take years to implement, to tackle seams that could arise if BPA joins a day-ahead market, agency staff said during a workshop.

BPA could face high implementation fees and operating costs under both SPP’s Markets+ and CAISO’s EDAM, but exact amounts are in flux.

El Paso Electric says it will join SPP’s regional day-ahead Markets+ service offering in a “strategic move … tailored” to meet expected customer load growth and evolving needs.

Arizona Corporation Commissioner Kevin Thompson said he thinks his state’s four major utilities may have erred in committing to joining SPP’s Markets+ instead of CAISO’s Extended Day-Ahead Market.

Arizona regulator Nick Myers, chair of the Markets+ State Committee, is drafting a document as part of SPP's compliance filing that better explains the role Western state commissioners will play in the day-ahead market's development and operations.

MISO’s Independent Market Monitor said ramping needs north of 10 GW are becoming increasingly common and MISO should expect challenges ahead as its solar fleet expands.

Powerex says it will fund the next phase of SPP’s Markets+ and “re-affirmed” its commitment to joining the Western real-time and day-ahead offering.
