LOAD-MODIFYING RESOURCES AVAILABILITY AND VISIBILITY OUTAGE COORDINATION ENHANCEMENTS The intent of Phase 1 for LMRs was to improve visibility and availability throughout the year. Through the enhancements to the LMR registration process, 9.5 GW of the 11.4 GW of LMR capacity indicated they would be available to be called on year round. Along with indicating more availability, the amount of LMRs with less than two hour notification time increased from 2.2 GW to 4.1 GW. Another enhancement to the availability and visibility of LMRs was modifications to testing requirements. To help facilitate the testing requirements during the accreditation process, MISO accounts for LMR performance during events in which they were called upon. If LMRs wish to opt-out of the testing requirements, they could do so, but with significant penalties associated with non-performance. These changes were instituted with the goal of increasing MISO’s visibility into the availability of LMRs during emergency events which can be called upon during emergency events. In order to increase availability, flexibility and visibility, MISO provided accreditation-related incentives to generators to notify MISO of their outage scheduling as early as possible. If circumstances required an outage to be scheduled closer to the operating day, the resource requesting the outage would have increased transparency of other planned outages and potential impacts. The Outages by Lead Time table shows the total outages by lead time throughout the year. When comparing outages across 2017, 2018 and 2019, outages scheduled in 2019 following FERC approval of MISO's RAN Phase 1 tariff changes show fewer overall outages. Phase 1's full impact on outage coordination will be the subject of further analysis.
