Ontario Power Generation Tech Stack

Ontario's largest clean power generator operating nuclear, hydro, and renewable assets

Utilities Toronto, ON 5,001–10,000 employees Founded 1999 Government Agency

Ontario Power Generation operates one of North America's most diverse generating fleets—nuclear, hydroelectric, solar, thermal, and gas—supplying nearly half of Ontario's electricity. The tech stack (Java, .NET, Azure, ServiceNow, Power BI) reflects a hybrid on-premises and cloud environment typical of critical infrastructure, while active adoption of Azure API Management, Azure Service Bus, and Kubernetes signals migration toward containerized, cloud-native operations. Heavy hiring in engineering and ops roles, skewed heavily toward interns, suggests aggressive ramp-up for major capital projects and the Pickering refurbishment effort.
