Case Study: Hydro-Québec TransÉnergie achieves optimal reliability and risk management with DIREXYON

Hydro-Québec TransÉnergie manages risk at the lowest possible cost thanks to innovative investment strategies in its critical assets

Hydro-Québec TransÉnergie, the transmission arm of Hydro-Québec, manages one of North America’s largest electric power networks with more than 800,000 assets and a rapidly aging portfolio. To keep service levels high while controlling cost, risk, and scarce labor resources, the team needed a way to rigorously test inspection, maintenance, and renewal strategies over a 50-year horizon. It turned to Direxyon and its modeling platform to support strategic asset investment decisions.

Direxyon implemented a centralized, drag-and-drop asset modeling solution that integrates degradation, risk, intervention policies, work synchronization rules, and financial analysis across asset categories. The platform now helps Hydro-Québec TransÉnergie generate realistic maintenance and investment scenarios, compare CAPEX and OPEX options, automate reports, and quantify impacts on rates for regulators. As a result, the organization can identify the best-return strategies, maintain required service levels, and make long-term decisions with greater transparency and auditability.
