Need for RAN The RAN initiative, instituted in 2017, came as a response to the increasing number of MaxGen emergencies events as outlined in MISO's 2018 Issue Statement Whitepaper. MISO recognized that changing market conditions were impacting the resource fleet’s operational characteristics and challenging the reliability and efficiency of market outcomes. At the RAN initiative inception, a total of 12 emergencies occurred beginning in the 2016-17 planning year through half of the subsequent planning year. That trend has continued as MISO entered MISO Market Capacity Emergency procedures 27 times through the summer of 2019. These events have occurred multiple times in every season reinforcing the notion that “every hour matters.” This differs greatly from the assumption that the system will be reliable for all 8,760 hours of the year as long as utilities have enough generation capacity to meet demand on the "peak hour" of the year, which typically occurs on an exceptionally hot and humid summer day. This white paper summarizes MISO’s actions regarding future stakeholder discussions during which it will continue to work collaboratively to enhance availability, flexibility and visibility.
