The company’s best-known products, PLEXOS and Aurora, are used by sophisticated utilities and system operators, power generation companies, analysts, price forecasting agencies, energy traders, consultants and academics. Energy Exemplar's software simulation results have appeared in numerous publications as they are auditable and renowned for accuracy and robustness. The simulation software results are used to minimize operational and investment costs, maximize profits, market design and market analysis.

History
1999: Glenn Drayton founded Drayton Analytics, which was later renamed Energy Exemplar. With a team of experts in operations research and economics, the company developed the initial power market modal based entirely on optimisation. This resulted in the first version of PLEXOS, released in mid-2000. PLEXOS, a software engine that provides high-level object models to build mathematical programming problems and handles all interactions with the solver.

In 2001, the company began building its global presence when PLEXOS was adopted by the Irish SEM as its standard. However, the California energy crisis in 2001 would play a major role in expanding the company. Spending almost two years travelling between Adelaide and California, Glenn launched PLEXOS Solutions with an office in Sacramento. With continued growth across Asia-Pacific and South Africa, Drayton Analytics transformed its business plan and its name. Energy Exemplar was launched in 2006.

Over the next eight years, Energy Exemplar continued to grow its customer base in the United States and Europe, and three additional regional offices opened to provide in-time-zone support. The company then achieved a significant milestone in January 2015 when the 1,000th installation of PLEXOS was completed, making it the most widely used, commercially integrated, energy market software in the world.

Acquisition
This significant growth trend caught the attention of the Riverside Company, a private equity group, which acquired Energy Exemplar in 2017. As part of its growth plan, Energy Exemplar acquired EPIS, LLC, headquartered in Salt Lake City, Utah that same year. The EPIS platform, Aurora, complemented the PLEXOS suite while the company also had significant brand recognition across the United States and Canada.

Business and markets
As of 2019, Energy Exemplar is the largest market simulation software company in the world. The corporation operates across all continents.

Energy Exemplar focuses on three industries sectors, electricity, gas and water. Within these sectors consultants, energy plant manufacturers, energy regulators, energy traders, system operators, utility providers, policymakers, research bodies, government agencies and ministries for energy are clients of Energy Exemplar. The company offers integrated product sets, including data sets to companies and government bodies of all sizes.

Products and services
PLEXOS, the flagship product, integrates simulations across the electric, water and gas systems. The PLEXOS platform integrates across long term, PASA, medium and short term scheduling. his platform is designed for full user control, transparency and accuracy across numerous constraints and uncertainties.

Aurora is an electric modelling forecasting and analysis platform that is designed for fast results with an intuitive user interface. The platform does not take long to implement and has many standard features that make it easy for users to get started out of the box.

Simulation-ready datasets, collected, cleaned and verified for users to start modelling without having to collect their own data.

PLEXOS Connect is a server that manages multiple runs of PLEXOS on a network of computers, either locally or on the cloud. It increases the speed, access and coordination of multiple runs of PLEXOS.

Partnerships
Energy Exemplar partners with commercial mixed-integer, linear and quadratic programming software providers such as Gurobi, CPLEX and FICO Express.
