Data centres hungry for power putting 'extraordinary pressure' on Hydro Ottawa

Hydro Ottawa is facing surging power demand from big customers, especially data centres, an "extraordinary pressure" that's only expected to grow.
CEO Bryce Conrad said customers are now seeking hookups for 34 large-load projects that will collectively require 1,075 megawatts, about 86 per cent of Hydro Ottawa’s average system load last year.
Conrad called that the highest volume in the company’s history, and said most want to get connected over the next two years. He said it's just the beginning.
"I am comfortable predicting that by the end of this year we will have received requests to connect that exceed the total amount of power that is used today by residents and businesses within the city of Ottawa," he said while presenting Hydro Ottawa's annual report to city council on Wednesday.
"We are being asked to build and support in the next two to three years what has taken us more the better part of 110 years to build, and to be clear, that growth is not expected to slow anytime soon. In fact, our expectation is that it will continue to scale exponentially."
About 60 per cent of those 1,075 megawatts are coming from data centres. Conrad said they aren’t “big hyperscalers,” like Amazon, Microsoft or Meta, but smaller companies — some of them working in generative AI.
He said government customers are also asking for big hookups, including for national defence.
But Conrad said Hydro Ottawa is sometimes facing lengthy delays making those connections due to supply chain snarls. Where it once took six or nine months to get crucial equipment like transformers, it can now take two years. In some cases, he said he’s waiting four years.
He said it’s tough competing with much bigger players in the U.S. that are looking for the same equipment.
"They’re buying 300 transformers, where we’re buying 15," he said. "That’s what it’s coming down to."
Despite the challenges, Conrad said all that demand is actually good news for Ottawa.
"It means Ottawa is growing," he said. "It means economic activity in the city. These are all good problems to have, we just need to be able to support that growth."
That’s just part of the pressure Hydro Ottawa is facing as it looks to keep up with population growth, electrify Ottawa’s transit system, upgrade infrastructure and protect its assets from cyber risks.
Conrad says it all requires Hydro Ottawa to double its capital investments over the next five years, compared to the previous cycle.
"We are staring down the barrel of a historic cycle of investment in the critical electricity infrastructure that powers our way of life," said Conrad.
"We are on track to almost double the work we did to strengthen and modernize the grid during the previous five-year period."
With that in mind, Conrad defended Hydro Ottawa’s recently announced rate increase. He said the utility remains competitive, amounting to an average hike of $5.87 per month this year.
But that was a smaller increase than the company was looking for when it went to the Ontario Energy Board. Conrad said that process was a huge headache, accusing the board's "deny and defer" mentality of causing problems for Hydro Ottawa.
"I appreciate the need to keep rates low, but when you’re on the cusp or in the midst of exponential growth in demand, they need to change their mindset," he said.
"Unfortunately, the rate application process that we just went through, there are no words to describe how ineffective and brutal that process was, and what I think is a colossal waste of time and money.”
He said it was so onerous that it took 16 months and cost Hydro Ottawa more than $15 million.
Yet Hydro Ottawa is making money. It’s paying the city a $22-million dividend this year, money that can be reinvested in city services.
"As an investment, we outperform the TSX," he said. "I think it’s safe to say any investor would be thrilled with this steady level of performance."
Councillors lauded Hydro Ottawa’s work, though they did have some concerns about reliability.
"The power outages are not long, they’re very short, but they happen," noted River ward Coun. Riley Brockington.
Conrad said Hydro Ottawa has achieved 99.97 per cent service reliability, but he admitted that’s cold comfort when the lights go off.
"Our goal, if there is an outage, is to restore power as quickly as possible," he said. "Every one of these outages is a learning opportunity for the team."
