Our proposed investment plan for 2028 to 2032

Electricity demand is increasing, and parts of Ontario's electricity system that have served people for decades need to be renewed. At the same time, storms are becoming more frequent and severe and security threats are becoming more sophisticated. These challenges affect the things people rely on every day, from keeping electricity available during extreme weather to powering growing communities.

Our proposed plan

Building a stronger grid for Ontario's future

Hydro One's 2028-2032 proposed investment plan was informed by feedback from more than 100,000 customers across Ontario. It focuses on the priorities that we were told matter most when looking towards the future.

68-88%

Of customers supported investments at or above the level proposed in our draft plans.

By the numbers

Our proposed plan in action

1,400 km

Upgrade approximately 1,400 kilometres of transmission lines to improve reliability and address aging equipment.

This is about the same distance as travelling from Toronto to Thunder Bay.

85,000+

Replace or refurbish 85,000 + distribution poles, to reduce equipment failures and make power lines more resilient during storms.

6,000 MW

Enable approximately 6,000 megawatts of new electricity capacity, that's enough electricity to serve about:

Customer bill impacts

What the proposed investment plan means for your bill

If the five-year plan is approved, the monthly bill for a typical year-round medium-density residential customer (R1) would increase by $0.50 in 2028 and by an average of $1.14 each year from 2028 to 2032 for transmission1. For distribution, monthly base charges would decrease by about $0.10 in 2028 and would remain unchanged in the following years, largely reflecting the impact of the Distribution Rate Protection Program (DRP) for eligible residential customers and a proposed customer refund. These estimates could change based on the OEB's decisions.

[1] Excludes Hydro One Sault Ste. Marie LP transmission, which would add an average of approximately $0.02 each year to the monthly bill.

What you need to know

Frequently asked questions

Why are rates changing?

Every five years, we submit a plan to the Ontario Energy Board (OEB) based on customer feedback, technical needs and regulatory requirements. Our recently submitted plan covers 2028 to 2032. The OEB reviews it through a public process and sets the rates needed to fund the approved work.

Why do we need to invest now?

Ontario needs more electricity as demand increases. At the same time, severe weather is affecting communities and some important equipment is reaching the end of its useful life.

Waiting could increase the risk of equipment failures, cause longer outages and increase costs in the future. Our proposed plan focuses on the most important work needed to manage these risks while delivering value for customers.

Who decides whether the plan is approved?

While we propose a plan based on the needs of the electricity system, the OEB has the final decision on which investments, rates and shareholder returns are approved.
