The Unified Energy Market Simulation Platform
It’s easy to be overwhelmed with the volume of data available and rate of change the energy industry is currently experiencing.
PLEXOS gives you the power to unify all your data streams – in any granularity – into a single, unified energy modeling and forecasting platform. Its powerful simulation engine analyzes zonal and nodal energy models ranging from long-term investment planning to medium-term operational planning and down to short-term, hourly, and intra-hourly market simulations.
- Co-optimization
- Hydro-optimization
- Nodal and Zonal analysis
- Gas planning
- Renewables and ancillary markets
- Multi-objective decision optimization
“PLEXOS allows us to understand physics, not politics. Everybody speculates, but that’s just opinion. What’s really powerful about energy systems modeling, and PLEXOS specifically, is that you can quantify and put numbers behind decisions.”

Driving Renewable Energy Investment Planning
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.
A Uniquely Unified Approach to Energy
PLEXOS is the only solution that unifies your market simulations across electric, water, and gas energy systems—allowing you to perform long- term planning, Projected Assessment of System Adequacy (PASA), medium-term and short- term scheduling, with each phase automatically connected to the others.
