MISO is preparing for emergency conditions this winter despite projecting 40 GW of excess capacity to meet the forecasted peak in January.

MISO is home to more than 4.5 GW of unregistered distributed energy resources, much of it for nonresidential use, the Organization of MISO States estimates.

For the first time, MISO has found a loss-of-load risk outside of summer months, and said it may be more evidence for seasonal capacity supplies.

MISO executives said they continue to seek ways to improve the RTO’s response to an increasing number of emergency events.

MISO’s effort to improve a key communication system will come too late to smooth summertime emergency procedures, stakeholders complained.

MISO want to improve how owners of LMRs interact with a communications system that some think hampered the RTO’s response to a grid emergency this winter.

MISO will reconsider its penalty exemption policy for already submitted transmission outages, officials told the Reliability Subcommittee May 2.

MISO expects to call on load-modifying resources this summer despite estimates it will have about 149 GW of projected capacity on hand.

MISO now cautiously estimates that the benefits of a seasonal capacity auction would outweigh potential drawbacks.

MISO’s most recent maximum generation emergency is yet another portent of its increasing need to rethink grid operations, execs told the Board of Directors.
