California-based Turlock Irrigation District has agreed to join CAISO’s Extended Day-Ahead Market in 2027.
Though BPA removed any uncertainty by selecting SPP’s Markets+ over CAISO’s EDAM, the debate over whether BPA made the right choice likely will heat up as the West confronts a split into two major markets.
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.
In the competition between two Western day-ahead markets — CAISO’s EDAM and SPP’s Markets+ — the two market operators have “sort of played off one another,” an industry observer said during a panel.

The Bonneville Power Administration elicited nearly 150 comments in response to the draft policy outlining its decision to join SPP’s Markets+ rather than CAISO’s Extended Day-Ahead Market.
