Oshawa Power MS7 Switchgear Upgraded with New eHouse Technology
November 25, 2025
This fall, Oshawa Power is completing upgrades at Municipal Substation #7 (MS7) with advanced eHouse switchgear technology, a key investment that will strengthen the reliability and safety of the city’s power supply for years to come.
What’s Changing at MS7
Oshawa Power’s new eHouse switchgear represents the next generation of electrical infrastructure:
- Modular and prefabricated: Built off-site, tested, and delivered ready for plug-and-play installation.
- Compact and efficient: Fits seamlessly into the existing substation footprint.
- Enhanced safety: Provides better protection for staff and equipment.
- Future-ready: Designed to integrate with digital monitoring and smart grid technologies.
Work on MS7 began in 2025 and will be completed by December. This marks the second of four planned switchgear replacements under Oshawa Power’s long-term Capital Rebuild Plan.
The upgrade will contribute to:
- Fewer unplanned outages
- Greater grid stability during extreme weather
- Long-term reliability as the city continues to grow
The Bigger Picture
This project is part of Oshawa Power’s proactive Municipal Substation Switchgear Replacement Program. By replacing aging infrastructure before failure, they can reduce outage risks, improve reliability, and prepare the grid for future energy needs including electric vehicles, distributed generation, and smart grid expansion.
“These upgrades are part of our commitment to maintaining a strong, modern, and resilient power system for Oshawa. Investing in infrastructure today means greater reliability and fewer disruptions tomorrow.”
