Permission granted by Stem UPDATE: May 18, 2021: FERC denied MISO's extension request May 17. The commission found "that MISO has not shown good cause for granting its request." Dive Brief: Midcontinent Independent System Operator (MISO) CEO John Bear has asked FERC to pay "considerable attention" to the operator's request for an extension in complying with an order to integrate storage on the marketplace. MISO is committed to greater participation of electric storage resources (ESRs), but federal requirements to bring them into the marketplace could compromise with members' carbon reduction goals, Bear wrote in comments filed May 10. That "has placed MISO in an unenviable position of choosing a path between conflicting goals that could jeopardize our capability to operate our 15-state wholesale grid reliably, efficiently and securely."
