Portions of the model may also be used for the commitment and dispatch phase (updated on 5 minute intervals) in operation of wholesale electric markets for RTO and ISO regions.

These ISO and RTO regions also utilize a GE software package called MARS (Multi-Area Reliability Simulation) to ensure the power system meets reliability criteria (a loss-of-load-expectation (LOLE) of no greater than 0.1 days per year). Further, a GE software package called PSLF (Positive Sequence Load Flow), a [[Siemens]] software packagepackages called PSSE (Power System Simulation for Engineering) as well as PSS SINCAL (Siemens Network Calculator), and [[Electrical Transient Analyzer Program]] (ETAP) by Operation Technology Inc.<ref>[https://etap.com Operation Technology Inc.]</ref> analyzes load flow on the power system for short-circuits and stability during preliminary planning studies by RTOs and ISOs.<ref>{{cite web|title=Siemens PSSE|url=https://www.siemens.com/global/en/home/products/energy/services/transmissionpss-distributione|work=www.siemens.com|access-smart-griddate=August 24, 2021}}</consulting-and-planningref><ref>{{cite web|title=Siemens PSS SINCAL|url=https:/pss-software/www.siemens.com/pss-e.htmlsincal|work=www.siemens.com|access-date=NovemberAugust 2624, 20182021}}</ref><ref>{{cite web|title=New York State Resource Planning Analysis (NYSPSC)|url=https://www.nyiso.com/public/webdocs/markets_operations/committees/mc/meeting_materials/2015-12-17/Agenda%2004_NYSDPS%20SRP%20Presentation_revised.pdf|work=www.nyiso.com|date=December 17, 2015|access-date=November 26, 2018}}</ref>
