MISO Dashboard

MISO's current resource adequacy construct depends on the probabilistic model being "at criteria," which is achieved when the model experiences a loss of load expectation (LOLE) of 0.1 days/year. There is a growing consensus amongst industry experts (including ESIG and EPRI) that alternative/additional resource adequacy metrics are more suited to capture system risk, especially as the bulk power system evolves to include increasing penetration of non-firm and energy-limited resources (such as wind, solar, and storage).

 As part of the 2024 STI program, MISO will perform a project to “[d]eliver a roadmap focused on the need to reform the use of Resource Adequacy criterion considering the Expected Unserved Energy (EUE) and other reliability metrics.” This will include an exploration of different metrics applied to the MISO footprint and an estimation of their effect on different aspects of the resource adequacy construct.
