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 and worldwide.

OSA is the developer of the PowrSym family of electric power system generation, transmission, and fuel supply models. 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. PowrSym has the ability to model systems at the "minute" level so as to capture the dynamic interactions of variable resources such as wind and solar with the system grid and conventional resources.
