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.
FERC approved an agreement between CAISO and LS Power to develop a transmission line that would deliver Idaho wind power into California and could help secure Idaho Power’s participation in the ISO’s Extended Day-Ahead-Market.
