Executive Summary MISO’s vision is to be “the most reliable, value-creating RTO.” Since its inception, MISO has converted the capacity from committed resources to energy in order to reliably and efficiently operate the Bulk Electric System. Beginning in 2016, MISO began experiencing a marked increase in the number of Maximum Generation Emergency (MaxGen) emergencies. As a result, the Resource Availability and Need (RAN) initiative was established to identify near-term solutions to increase the conversion of committed capacity resources into energy during times of need. Five key drivers of change were identified as major contributors of increasing MaxGens emergencies. These five drivers identified market conditions which would impact reliability in the near-term and become even more prominent in the future. In early 2019, MISO released the MISO Forward report, which looks at the impacts of three major trends -de-marginalization, decentralization and digitalization. The 3Ds will intensify the operational impact of these five drivers of change as MISO moves into the future. Solutions implemented now must not only address near-term issues, but they must also take the future portfolio into account. To that end, RAN is exploring one of the most complex and critical questions in the industry: What changes should MISO make to address near-term reliability challenges while also preparing for a future portfolio likely to be comprised of far less thermal dispatchable resources, more emergency-only resources, and a large percentage (e.g., 40 percent) of renewable resources? Additionally, how does MISO sequence and align enhancements to not only address near-term issues but also provide an effective progression of changes over time? This transition away from legacy thermal units to new technologies, including more intermittent and emergencyonly resources, requires planning, markets and operations to also evolve. MISO and stakeholders must work to identify and implement new solutions to address the challenges and take advantage of the opportunities presented by the unprecedented scale and speed of industry change. This paper will describe the Resource Availability and Need (RAN) initiative and MISO's plan to address issues in the Explore, Decide, Do, Done framework. 1
