“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.”

Transformational Decision Support for Energy & Utility Organizations

PLEXOS is a unified energy modeling and forecasting software 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.

While other simulation software only models energy markets separately, PLEXOS allows you to understand the market variations across the entire energy landscape. The result: co-optimized interdependent energy market simulation that enables you to uncover hidden value.
