By the numbers
Reliable by design
Our 99.99% reliability score is the product of years of planned investment, proactive maintenance, and smart grid automation. When outages do occur, our team responds fast.
Each winter we scan the entire grid with infrared cameras, flagging heat anomalies that signal component degradation before failure can occur.
153 porcelain insulators replaced in 2025 with modern hydrophobic polymer alternatives, reducing outage risk from weather effects and contamination.
Our territory is divided into three zones. One zone is comprehensively trimmed each year in partnership with utility arborists, on a three-year cycle.
40% of our grid can automatically detect, isolate, and reroute around faults. In 2025 we completed SCADA integration across our full 44kV network.

Despite the depth of experience he brings, Rehan remains as curious and committed to learning as ever.
Planning for what's ahead
2025 marked the end of our current five-year planning cycle. We filed our next Cost of Service application with the Ontario Energy Board, outlining our investment priorities and rates through 2030.
EV registrations in Oshawa
Increase in adoption since 2022
We filed our next five-year plan with the Ontario Energy Board covering 2026 to 2030. The OEB is expected to set new rates by June 2026.
With $400,000 from Natural Resources Canada, we are piloting a local DSO model to coordinate distributed energy resources and keep costs down for customers.
$400K NRCan GrantWe submitted four proposals for alternatives to traditional grid investment, using demand response, energy storage, and local generation to serve growing demand at lower cost.
We secured a $100,000 grant from Natural Resources Canada to install 20 new EV chargers in 2026, removing barriers to adoption across the city.
$100K NRCan GrantFinancial performance
Each five-year cost of service filing requires balancing necessary grid modernization investments with affordable rates for residential and commercial customers across Oshawa.
Our focus on operational efficiency means every dollar invested in our grid goes further. In 2025, this discipline produced a Capital Efficiency Ratio of 1.29 — for each dollar invested, $1.29 of in-service assets are connected to the grid.
Oshawa Power's 5-year average Cost per km of Line and Cost per Customer register 4.4% and 14.8% lower than the Ontario average, further demonstrating how our investment philosophy benefits both the strength of our grid and the affordability of our service.
