PowrSym History

Operation Simulation Associates, Inc.

OSA is incorporated in Georgia and headquartered in Ringgold, GA. OSA was founded in 1983. OSA provides software and services for the electric power industry with clients in the USA, Europe, and Australia.

OSA is the developer of the PowrSym family of electric power system generation, transmission, and fuel supply models. The PowrSym product family is:

  • The PowrSym4 Model is a unified generation system, hydro system, renewable resources, electric grid, and natural gas grid simulation that optimally dispatches resources to meet the electric loads, natural gas demands, and heat supply demands on an hourly basis for study periods ranging from weeks to several years.
     

  • PowrCast  is a combination of the PowrSym4 model and the published EPA data for each of the 64 regions in the USA as defined by EPA. PowrCast model runs are offered as a service by OSA on a per-study basis. PowrCast enables collaborative studies by diverse parties using a common platform to compare alternatives with objective functions of cost, emissions, and reliability.
     

  • The Maintenance Scheduler uses the PowrSym4 computing engine to optimally schedule generating unit planned outages minimizing costs while protecting system reliability.
