As a result of MISO’s response to FERC Docket No. EL23-46-000, the system-wide UCAP/ISAC conversion ratio will be updated.  This ratio is used to determine Schedule 53 resource’s Seasonal Accredited Capacity (SAC).
 
The following ratios will be used for the upcoming 23-24 Planning Year:

 
SeasonRatio
Summer1.049
Fall1.078
Winter1.059
Spring1.087
 
Below is a comparison to the previous calculated ratio:

Summer1.0491.074-0.03
Fall1.0781.182-0.10
Winter1.0591.099-0.04
Spring1.0871.166-0.08
 
The drivers for the ratio changes include:
·       Reflecting the restoration of inadvertently lost Generator Planned Outage (“Outage”) exemptions
·       Incorporating fulfilled GVTC test extensions for resources not included in the original Dec 15 ratio
·       Refreshing the list of resources qualifying for Schedule 53
 

MISO plans on updating Schedule 53 SAC values in the MECT by COB Friday, March 31.
