CARMEL, Ind. — Today, the Midcontinent Independent System Operator (MISO) projected adequate resource availability to meet the 2021 summer peak demand with warmer-than-normal temperatures forecasted throughout the MISO footprint. The summer peak forecast is 122 GW with 146 GW of available capacity. During the 2021 Summer Readiness Workshop, the regional transmission organization (RTO) also shared that high load demand and high outages could drive operational challenges this summer.

“We expect sufficient resources to meet the summer peak demand based on information we received from our members and stakeholders,” said Renuka Chatterjee, executive director – system operations at MISO. “We will continue to work with them to ensure operational readiness regardless of the conditions, season or time of day.”

2020 Lessons Learned

The increase in abnormal weather events in 2020 provided the RTO with significant lessons learned that has helped MISO prepare for the upcoming season. These include:

“This year we focused on lessons learned from the challenges we experienced last summer,” said Tag Short, MISO’s director – balancing and interchange operations. “We saw an increase in volatile weather in 2020, which represented the biggest impact on our system since we integrated our South Region.”

These findings highlight the immediate need for MISO and its members to prioritize market redefinition, long-range transmission planning, market system enhancement and a focus on operations of the future – the four elements of MISO’s Response to the Reliability Imperative.

 As a part of the workshop, MISO also hosted Tim Ponseti, the SERC Reliability Corporation’s vice president of operations, who discussed the impacts of the record-breaking hurricane season in 2020 and Joe Riels, Cooperative Energy’s director – system operations, who reviewed his organization’s summer preparation and coordination with MISO.
