Continued reforms to improve scarcity pricing and price formation are necessary for Availability (the ability of transmission and energy resources to meet requirements at all hours). 

This project includes reviewing the Value of Lost Load (VOLL) assumption and its impact on demand curves. As such, "IR060 - Improved Contingency Reserve Demand Curve that reflects VOLL" has been closed and is being addressed here, through IR071.

This issue was submitted by Potomac Economics, MISO's Independent Market Monitor (IMM) and is synonymous with State of the Market (SOM) recommendations 2016-1.
