Riverside Invests in Australian Simulation Software Company

Riverside Invests in Australian Simulation Software Company

The Riverside Company has invested in Energy Exemplar, the developer and marketer of the PLEXOS suite of energy market simulation and modelling software. PLEXOS is the best-in-class integrated simulation software for electric power, water, gas and renewables. It has a global customer base, with greater than 90% of revenues generated outside Australia.

Energy Exemplar has more than 150 customers in 47 countries globally. Based in Australia, with offices around the world, the firm employs 55 staff, including 16 software developers. PLEXOS is an international leader thanks to Energy Exemplar’s sustained R&D investment and thought leadership in energy market simulation.

“Energy Exemplar’s product suite and track record is exceptional, with significant room to expand in a fragmented global market with a number of positive industry trends,” said Riverside Partner Nick Speer. “PLEXOS offers better product features that materially improve the decision-making capability of its sophisticated customers in an environment where complexity is ever-increasing.”

Riverside’s global footprint is a perfect match for Energy Exemplar. Its international resources and experienced operating team will work with Energy Exemplar to continue the company’s international, cross-commodity expansion.

“Energy Exemplar is a growing company and we’re eager to partner with the team to support and accelerate their growth trajectory,” said Riverside Partner Steven Spiteri. “We plan to invest in R&D so management can retain and strengthen its competitive edge while boosting sales and marketing efforts in international high-growth markets.”

Riverside has extensive experience in software investing and looks forward to a strong and successful partnership with Energy Exemplar founder Glenn Drayton. The firm plans to source and integrate complementary add-on acquisitions throughout the hold.

“Riverside’s deep global resources will support Energy Exemplar and PLEXOS in keeping ahead of the curve in a world where simulation and co-optimization of resources across many industries is increasingly important,” said Drayton. “Their industry experience, operating track record and international capabilities will combine to sustain rapid growth for our company.”

Working with Speer and Spiteri on the deal for Riverside were Senior Associate Nicholas Pejnovic and Senior Associate Kevin Xu.

Barings provided debt for the transaction, and Riverside was assisted by Bain & Company (commercial), KPMG (financial), Deloitte (tax), and Herbert Smith Freehills (legal).

The Riverside Company

The Riverside Company is a global private equity firm focused on making control and non-control investments in growing businesses valued at up to $400 million. Since its founding in 1988, Riverside has invested in more than 480 transactions. The firm’s international portfolio includes more than 80 companies.

Everything Old is New Again

As Energy Exemplar enters the closing stages of a project with the Australian Energy Market Operator (AEMO) to deliver PLEXOS as an upgrade to the market system in the Australian NEM known as “MT PASA”, we come to realise the quintessential case of “Sooner or later, everything old is new again.”

The story of MT PASA and of how the outage optimization phase of PLEXOS got its name “PASA” goes back to 1997 when the Australian electricity market was a still a toddler. Glenn Drayton was working in New Zealand for an operations research consulting firm called Core Management Systems (CMS) and had just finished his Ph.D. thesis, focussed on electricity market design. Out of that work came the electricity market simulation software, WEMSIM (which would eventually become PLEXOS).

The key enabling technology inside WEMSIM was AMMO (ActiveX Mathematical Modelling Objects). This API connected Microsoft’s VBA to CPLEX, which meant that commercial grade mathematical programming could be easily integrated into any VBA-aware program like Excel. In hindsight, AMMO is the best idea Glenn claims to have come up with because today it underpins the PLEXOS engine.

CMS consultants like Dr E. Grant Read (inventor of dual dynamic programming and Glenn’s Ph.D. supervisor) and Brendan Ring (who studied at University of Canterbury with Glenn and today is one of the world’s leading experts in electricity market design) were involved in the design of the Australian NEM. A US firm called ESCA built the market software systems including the market clearing engine SPD (Scheduling, Pricing and Despatch), affectionately known as “spud” and later renamed to NEMDE.

ESCA was under pressure to deliver the market systems but were short on time, especially with implementing “MT PASA” (“Medium Term Projected Assessment of System Adequacy”). This report looked ahead two years and computed available reserve generation capacity announced maintenance schedules, transmission availability and the forecast peak loads. Its key outputs were the expected reserve levels at the peak of each day in each region in the NEM.

While Glenn was upgrading WEMSIM to optimize the placement of outages, CMS volunteered to supply the MT PASA software until such time as ESCA could write the “official” version. The stars aligned and Glenn began writing MT PASA for the NEM.

Glenn realised that consulting companies are not good places to write software. Consulting and software cultures are very different and writing software whilst consulting is a recipe for a poor product, a philosophy that Energy Exemplar maintain to this day by not consulting.

So, it was because of MT PASA that the maintenance optimization phase of PLEXOS got the name PASA, and the “temporary” MT PASA Glenn originally wrote for the NEM lasted several years before ESCA finally got around to replacing it.

Today, we have come full circle. The original, simple, MT PASA has done its dash. It has not kept pace with the introduction of intermittent generation. AEMO recognise that a full Monte Carlo simulation which considers renewable intermittency as well as generator forced outages is paramount for meaningful mid-term indicators of shortage or surplus.

And so, as PLEXOS becomes set to replace MT PASA by November 2017, we find that sooner or later, everything old is new again.
