MISO is beginning a study to assess its frequency response performance and identify needed improvements to mitigate generation loss.

MISO told stakeholders that its own data set might have been partly to blame for generators not responding efficiently to dispatch instructions.

MISO is seeking stakeholder input on how to address declining frequency response capability within the RTO.

MISO’s Reliability Subcommittee last week narrowly approved a more stringent process for deciding on pseudo-tie requests.

MISO will ask FERC to approve new pseudo-tie rules next year, officials said during a Nov. 8 special conference call of the Reliability Subcommittee.

MISO will have a 15.8% planning reserve margin for the 2017/18 planning year, up slightly from last year, according to the RTO’s loss-of-load-expectation study.

MISO told the Reliability Subcommittee that it will have an easier time than expected complying with EPA’s Cross State Air Pollution Rule (CSAPR).

All energy storage resources wanting to qualify as capacity should register as behind-the-meter for the 2017/18 planning year, MISO said at last week’s two-day Resource Adequacy Subcommittee meeting.

The MISO Reliability Subcommittee discussed improving frequency response, pseudo-tie congestion management, and its 2016/17 winter Coordinated Seasonal Assessment.

The Reliability Subcommittee is concerned about the reliability of MISO’s frequency response under a changing resource mix.
