Puget Sound Energy said it is joining Markets+, marking another win for SPP shortly after the Bonneville Power Administration issued its final market policy in favor of the day-ahead market.
Bonneville's final record of decision will come as little surprise to those who’ve been following market developments in the West.

CAISO sidelined a proposal to provide an additional market run for gas resources due to a lack of information on the subject and a need for operational experience with the ISO’s Extended Day-Ahead Market.
