Demand for electricity in Ottawa continues to grow and energy needs in the community are increasing. The Dagmar Infrastructure Renewal project is a multi-phase, multi-year initiative being completed as an essential requirement to upgrade the distribution system in North Vanier. We’re replacing aging equipment and converting parts of our electricity infrastructure to ensure power is available in the community for customers now and in the future.
This initiative is more than a single project; we’re prioritizing essential projects such as this one across our service territory as a core component of Hydro Ottawa's commitment to modernizing our entire electricity grid. These proactive, sustained investments ensure we can provide a reliable and ultimately more sustainable electricity supply for all our customers.
Why this project is important
The Dagmar Infrastructure Renewal is important to ensure we can continue to meet the capacity and reliability needs of the community by upgrading the power distribution infrastructure. The project also focuses on mitigating equipment failure while creating redundancies, promoting a more consistent power supply.
What this project will include
As part of the Dagmar Infrastructure Renewal project, we will:
- upgrade a total of 291 electrical poles
- install 120 new electrical transformers
- install approximately 15 kilometres of overhead primary and secondary conductors
- install new underground duct work and 2 kilometres of underground primary conductors
How Hydro Ottawa customers will benefit from this project
By increasing the overall electrical capacity, we are creating a more reliable power supply to match the growing needs of the community. This upgrade is essential to maintain the stability and effectiveness of the distribution system, leading to less disruptions and unplanned power outages. Additionally, the project replaces aging Hydro Ottawa infrastructure and equipment that have reached the end of their lifespan, safeguarding the safety and efficiency of the electrical grid.
This project is one of many future-planning projects we are spearheading to make our electricity system as resilient as possible.
