Unlimited flexibility

Model Your Way

Configure PLEXOS with a limitless collection of scenarios, customized constraints, conditional variables, physical elements, simulation horizons, durations of simulation period, phases in the integration and model resolution.

This data-driven flexibility creates a dynamic solving engine: it adapts to your data producing the right balance of detail and performance while giving you ultimate scalability and ultra-fine control.

PLEXOS is also completely transparent. If you want to see how the solution delivered the results, all equations, objective functions and constraints are open for you to review.

  • Run real-world studies for greater accuracy
  • Analyze hundreds of scenarios for richer insights
  • Co-optimize electricity, water and gas systems
  • Simulate competitive behaviors
  • Calibrate your simulations to maximize accuracy versus speed
  • Demonstrate auditable results
  • Complete control of constraints in your modeling runs
