CAISO is proposing a set of tariff changes for submission to FERC early in 2026 to help ease participants into the ISO’s new Extended Day-Ahead Market.

CAISO's Department of Market Monitoring has asked the ISO to re-evaluate its intertie scheduling proposal for the Extended Day-Ahead Market due to potential impacts on market participants.

At one of the most well attended workshops of the year, CAISO staff described new processes for scheduling intertie resources and resource adequacy imports in EDAM.
