Features of the simulator
Detailed renewable and fossil generation technical-economical characteristics. Deterministic and stochastic unit commitment on/off decisions, random outages, temperature dependency and various autoregressive models for wind speed, solar radiation and natural inflows. Multiple fuels and Combined Cycle modelling details featuring non-convex heat rates, start-up/shutdown profiles, complex fuel transitions and operational modes.
Optimal power flow with losses fully integrated with dispatch and unit commitment. Security and n-x contingency constraints (SCUC), DC lines and phase shifters. Generic constraints and interface limits, transmission aggregation, Monte Carlo simulation, multiple AC networks, 10,000’s buses and lines, nodal pricing and price decomposition.
Planning Optimal generation and transmission expansion planning over 30+ year timeframe. Optimal NPV of investment and production costs, chronological expansion for detailed ramping, fast frequency control and replacement reserves investment opportunities. Stochastic 2-stage optimization support, LRMC, optimal emission target decommissioning, capacity payments and reliability indices.
Highly detailed cascading hydro networks featuring GIS visualization from Google Earth. Efficiency curves, head storage dependency, waterway flow delay times, spillways, evaporation, deterministic and Stochastic solutions over any horizon. Seamless integration with detailed short-term unit commitment via target volumes or future opportunity cost decomposition. Pump storage energy and ancillary market co-optimization.
Ancillary service provision co-optimised with generation dispatch and unit commitment. Detailed treatment of start-up and shutdown combined with ramping and reserve interaction minute-by-minute. Multiple reserve classes including spinning, regulation, up and down and replacement services.
Generation dispatch constrained by emission limits and/or reflective of emissions price and number of emission types. Flexible grouping for emission constraint sets over any timeframe including multi-annual.
An integrated gas-electric model allows detailed modelling of the physical delivery of gas from fields, through pipelines and storage to gas and electric demands. Gas and electric models are solved simultaneously allowing decision makers to trade-off gas investments, constraints and costs against other alternatives.
Comprehensive financial reporting to Generator, Region and Company level. Dynamic bidding of generation resources reflective of contract position and/or medium term revenue requirements based on recovery of build costs from capacity expansion planning. Bertrand and Cournot games, flexible user-defined mark-up definitions and automated schemes such as RSI.
Scope and Compatibility
Highly configurable timeframe and simulation interval as short as 1-minute. Choose between regional, zonal and full-nodal network detail. Multiple pricing, uplift and capacity payment options to support various market rules. Choice of commercial mathematical programming engines (CPLEX, Gurobi, MOSEK, Xpress-MP).
Quality tested to ensure the best product and fastest delivery
PLEXOS is built using the “Agile” software development process to meet your demands while delivering the best working software and regularly to you. Read about our quality process in this document and how it can greatly benefit you.

PLEXOS supports multiple licensing modes including:
- Standalone (node locked) licensing
- USB dongle
- Server-based licensing
PLEXOS requires a licence for one of the third-party mathematical programming packages listed on our Partners page. These licences are provided with PLEXOS by Energy Exemplar.
PLEXOS software and some of the mathematical programming packages are free for academics, but must be registered with a degree-issuing academic institution.
In the last few years I have successfully used PLEXOS for modelling different electricity markets. Its functionality and flexibility to model markets with different rules, the auditability of the optimization problems, the capability to model a market with different levels of detail within a single database, and the possibility of including your own custom-made algorithms through Open PLEXOS sealed the deal for me.

PLEXOS gives us the right combination of simplicity and complexity, allowing us to include all of the relevant features of the regions we are studying whilst retaining control over the size of the model. The model framework is flexible and transparent enough to allow us to build meaningful models very quickly, and enables us to easily develop our model as our knowledge of the market changes, as our interests evolve, and as our modelling skills improve.

PLEXOS is a valued tool which provides CEZ with more insight into European power and carbon market dynamics. The analysis of fundamental drivers and their impact on the future balance of power systems is beneficial for both trading and investment decision purposes.
We are using PLEXOS for some time now and are feeling comfortable because of its intuitive user interface as well of its solving capacities. Having complex models to be solved, PLEXOS still computes the results in a fair period of time. The graphical solution viewer enables us to quickly check our models’ consistency. PLEXOS helps us understand cause and effect of market characteristics.
