As Ontario's largest electricity transmission and distribution provider, we are building a better and brighter future for all. We have a responsibility to deliver safe and efficient electricity to our customers, across the province and we are also committed to serving the communities where we live and work.

Built by customers, for customers.

The Investment Plan was directly informed by the feedback of almost 50,000 customers with an evaluation of our current and future system needs.

“Our plan will make smart investments to significantly reduce the impacts of power outages for our customers. With much of our system built in the 1950s and 1960s, it is time to invest in renewing or replacing critical infrastructure in almost every community across the province. Every dollar we invest comes at a cost to our customers, which is why this plan was directly informed by the feedback of almost 50,000 Ontarians. The majority of customers told us they support proactive investments in a resilient and reliable system prepared for climate change.”

We would like to thank all of our customers who participated by providing feedback to us on our plan.
 


 

Our role in the system

Hydro One proudly serves 1.4 million customers, delivering and transmitting electricity to every corner of Ontario. We serve businesses, large and small and energize approximately 40 per cent of Canada’s economy.


Distribution

1.6 million poles

1.4 million customers

That's about one pole per customer

Our service territory covers 75% of Ontario


Transmission

We energize approximately 40% of Canada's economy

The province's clean energy mix means that 96% of the electricity we deliver is clean

Attracting businesses to the province depends on a strong transmission system

Understanding our rate application

We are filing our first combined transmission and distribution rate application the five-year period from 2023 to 2027.

Our plan is developed through:

  • An evaluation of our current system and future system needs.

  • Understanding, through customer feedback, the current and future needs of our customers.

  • Balancing affordability with what the system needs and our customers' feedback.

  • Our proposed Investment Plan will renew or replace critical infrastructure, improve resiliency and reliability, prepare for the impacts of climate change, and support economic growth and customer choice.

  • Hydro One will seek approval from the Ontario Energy Board (OEB) to fund its plans. The OEB and consumer groups will review our plan through a public hearing process.


What customers told us

In almost every community we serve equipment needs to be renewed or replaced. To plan for the next five years, we engaged with almost 50,000 Ontarians who told us they wanted a more resilient electricity system that is ready for the future.

85%

of customers want us to replace aging infrastructure when or before it starts to deteriorate

77%

want us to make the investments necessary to keep the business running safely and reliably

60%

would support proactive investments to prepare the system for more severe weather

About half

of customers wanted us to invest in infrastructure faster than our draft plan

What is needed?

The majority of our system was built in the 1950s and 1960s

1 in every 20 wooden poles is now at risk of failure

Nearly 1 in 4 steel transmission towers are more than 80 years old

Close to 4,000 km of high voltage power lines need to be replaced


Our plan

Our five-year Investment Plan invests in a resilient electricity system to reduce the impacts of power outages for our distribution customers by approximately 25%.

We will prepare our grid for the impacts of climate change and plan to invest in nearly every community we serve.

Our plan will result in:
