Our History
1997
In 1997, Glenn Drayton was completing his doctoral thesis at the University of Canterbury. During his studies, he participated in an energy market research group with a strong focus on modeling. He began creating a rapid application development library, which allowed him to complete industrial-scale mathematical programming.
1999
After his thesis, Glenn took a consulting role with a transmission system operator and quickly saw the need to test a range of designs in the energy market. In 1999, he expanded the original program written during his thesis and founded a company under the name Drayton Analytics. By mid-2000, the first version of PLEXOS was released.
2002
Before long, PLEXOS was officially adopted by the Irish SEM as its modeling standard and the software began developing a global presence. Demand also increased dramatically due to the effects of the California energy crisis in 2002.
2006
In 2006, Drayton Analytics transformed its business plan and was renamed to Energy Exemplar. Energy Exemplar grew its customer base in the United States and Europe by opening three regional offices with in-time-zone support.
2015
The company achieved a major milestone in 2015 when the 1,000th installation of PLEXOS was completed. This made PLEXOS the most widely used energy market software in the world.
2017
Two years later, this success caught the attention of the Riverside Company, a private equity group that acquired Energy Exemplar. As part of the growth plan, Energy Exemplar also acquired EPIS, LLC. The EPIS platform, Aurora, complemented the PLEXOS suite and increased brand recognition across the United States and Canada.
2024
In 2024, Energy Exemplar entered a transformative phase when it was acquired by Blackstone and Vista Equity Partners. These partnerships enabled the acquisition of Adapt2 Solutions, further enhancing Energy Exemplar’s capabilities and cementing its role as a leading provider of end-to-end energy modeling solutions.
Today
Energy Exemplar continues empowering transformative energy decisions, helping clients worldwide model and optimize cleaner, smarter, and more resilient energy systems.
