The WMS monitors Public Utility Commission of Texas rulings as they apply to wholesale markets and market participants.

Among its many functions, the WMS provides input into the methodology for determining competitive constraints, changes to ancillary services (AS) and the evaluation of resource adequacy in the ERCOT region. The WMS also monitors the AS market operations and management of system congestion.
