CAISO marked a key milestone in its Western expansion efforts after FERC approved nearly every aspect of its proposed Extended Day-Ahead Market.

CAISO asked FERC to approve the rules for its EDAM and revisions to its existing day-ahead market, intended to more accurately forecast load.

Changes meant to improve the performance of CAISO’s day-ahead market and the planned day-ahead expansion of its Western Energy Imbalance Market won board approval.
