Tam Wagner, P.Eng., Director, Energy Efficiency

When it comes to building diverse skills and charting an enviable career path, you don’t have to join a huge organization. Just ask Tam Wagner, who says there’s no one-size-fits-all approach to achieving your goals at the IESO – her love of learning has taken her from the control room to leading teams that support real-time and future reliability.




Ella Kokotsis, PhD, Senior Advisor, Market Assessment and Compliance Division

Working in the electricity industry wasn’t something Ella ever considered when completing her PhD. But 21 years after taking on her first IESO contract, Ella continues to play a vital role on the team that leads market oversight, assessment and compliance, while building her reputation as an expert, author and commentator on all things related to G7 accountability.




Saeed Mohamed, Program Analyst, Indigenous Relations

As a U of T student interested in community building, Saeed Mohamed never imagined he’d be able to realize his passion for helping remove barriers faced by marginalized communities in either a government agency or in the electricity industry. But today’s he’s doing that in both – thanks, in part, to his co-op experience, which opened doors to new possibilities.




Joseph Ricasio, P. Eng., Manager, Operations Planning

When it comes to significant grid events, Joseph Ricasio has seen it all – from forest fires to ice storms and tornadoes – since joining the IESO in 2007. But on a team where addressing contingency is second nature, and where there’s always a Plan B and Plan C, it’s the day-to-day contributions to system reliability that make the difference.




David Le, EIT, Power System Analyst

For David Le, learning in an academic setting is one thing. But it’s the exposure to the inner workings of a power system, and the opportunity to put his grounding in power system theory into practice in the real world – and in real time – that led the former co-op student to return to the IESO to build his career.
