Plan, Design and Build
a Grid for the Future

We are planning, designing and building a grid that meets the needs of Ontarians today and into the future. As we prepare for more severe storms, we will consider climate change in our planning to increase resiliency and lower our environmental footprint. We will also continue to minimize our environmental footprint by prioritizing and managing the environmental impacts of our business.

Building a Grid for the Future

We are investing in existing infrastructure to maintain a reliable and resilient grid, while embracing new technology for tomorrow. These investments help ensure we have a grid that is more reliable, resilient to fluctuations in weather, minimizes the risk of environmental impacts and can meet the demands of future industries in the province.

We invested approximately $1.7B in 2019 to expand the electricity grid and renew and modernize existing infrastructure. Learn more about our major projects.
meeting the energy
demands of ontario

We recently completed the installation of our distributed energy resource management system (DERMS), a technology that enables us to have real-time control of the electricity flowing through our distribution system. This technology will help to meet the increasing energy demands of the province.

Climate Change

We are committed to reducing our carbon footprint and to managing the impacts of climate change on our business.

A critical element of building a sustainable grid for the future is to ensure we reduce our greenhouse gas emissions (GHG) emissions. In 2019, Hydro One avoided 8,075 tCO2e of emissions as a result of renewable energy technology, conservation programs, and the increase of customers choosing the e-billing option on their bill. These avoided emissions are equivalent to a year’s exhaust from 2,300 passenger vehicles1.

GHG Emissions Classification

Scope 1: Direct emissions from sources owned or controlled by Hydro One
(e.g., use of fossil fuels in our owned and operated fleet vehicles).

Scope 2: Indirect emissions from the generation of acquired and consumed electricity, steam, heat, or cooling from sources owned or controlled by an external organization (e.g., from energy purchased).
greening our fleet

Decreasing the amount of fossil fuels Hydro One’s vehicle fleet consumes will help us to reduce our overall carbon footprint. That is why we are planning to convert 50% of our fleet of sedans and SUVs to electric vehicles or hybrids by 2025. We are also developing a GHG metric tracker to better monitor carbon dioxide emissions and we are working to reduce the number of vehicles we use. In fact, since 2017 we have removed 1,200 vehicles from our fleet.

Environmental Management

Our environmental management programs play a critical role in helping us manage our impacts on the natural, built and social environments, as well as in lowering our environmental footprint.

Our environmental management plans and components are linked to our top environmental considerations:

Hydro One is actively exploring building automation technologies to help reduce our overall energy consumption. These technologies could ultimately make our facilities’ energy use carbon neutral, extend the life of our assets and reduce our costs.

In 2019, our Real Estate team began piloting new sustainable energy management solutions for potential deployment across our facilities. Hydro One’s Connected Buildings Pilot is testing a new web portal at four Hydro One sites – Perth, Sudbury, Markham and Barrie – that uses enhanced web-enabled thermostats, sensors and controllers to allow for real-time monitoring of electricity consumption and performance at these buildings. This remote-control command system generates automatic alerts should there be excessive energy consumption in building heating and cooling systems, baseboards, lighting panels or main building service.

In 2020, the pilot is running in Perth and Sudbury and initial results indicate the system is generating savings and insights on GHG emission reductions. The pilots in Markham and Barrie are in process but delayed due to COVID-19.
