MISO is nearing its goal of an October FERC filing to solidify its first, limited set of storage-as-transmission assets rules.

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

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

In the wake of its Jan. grid emergency, MISO pledged to further study generation cutoffs in extreme temperatures and improvements to its load forecasting.

MISO filed new requirements on outage coordination despite the fact that some stakeholders still aren’t entirely sold on the plan.

Until MISO files changes to implement stricter requirements for planned outage notification, stakeholders offered alternatives softening the proposal.

MISO officials are still hashing out how they can best model and analyze energy storage-as- transmission in the RTO’s transmission planning process.

Several MISO stakeholders are criticizing Tariff filings the RTO plans to make by the end of the year to free up an additional 5 to 10 GW of capacity.

Stakeholders are skeptical of MISO's proposed Tariff revisions imposing stricter outage rules and load-modifying resource requirements.

MISO staff now say they will zero in on three short-term resource availability and need fixes that can be rolled out early next year.
