Boy has it been a foul month for Hydro-Québec — and April isn’t even over but.

It began April 5, when an ice storm devastated timber throughout the Higher Montreal area and induced widespread blackouts, a few of which lasted as much as every week. Subsequent got here a weird cyberattack, claimed by a pro-Russian group, that rattled clients despite the fact that it didn’t have an effect on service. Then Tuesday’s energy outage, the results of upkeep work at Labrador’s Churchill Falls producing station, plunged near 500,000 customers in the dead of night earlier than service was broadly restored within the afternoon.

At a time when the province is embarking on an power transition that may require an increasing number of electrical energy to exchange heating oil and different fossil fuels, many Quebecers are left to surprise: How dependable is our electrical energy provide?

Some observers have urged burying distribution strains to buttress the system — however not everyone seems to be satisfied, least of all Hydro-Québec. What specialists do agree on is the necessity for the corporate to step up efforts to safeguard its infrastructure and scale back blackout dangers.

“It’s arduous to know if Tuesday’s outage is indicative of a pattern or if it’s only a coincidence,” Pierre-Olivier Pineau, an power coverage specialist and professor on the HEC Montréal enterprise faculty, stated in an interview. “What we do know is that Hydro-Québec has an growing old transmission and distribution community, and that local weather change goes to create much more stress on that community.”

Normand Mousseau, a physics professor at Polytechnique Montréal who’s scientific director of the engineering faculty’s Trottier Power Institute, says Quebec ought to use the ice storm as a “purpose to behave. There are a collection of measures we should implement to enhance the safety of the community, together with burying distribution strains in densely populated areas. Let’s cease losing time,” he stated in an interview.

Mousseau, who co-presided a provincial fee on power points in 2013-14 that really useful burying distribution strains, doesn’t mince phrases when describing the corporate’s technique.

“Hydro-Québec is a mammoth that doesn’t like change,” he stated. “There’s no will on their half to bury energy strains.”

Some observers, like College of Ottawa economics professor Jean-Thomas Bernard, assume the ice storm reveals the necessity for an audit of the distribution community. Whereas Hydro-Québec studies on energy outages and their causes, society would profit from one other viewpoint, he stated.

“We’d like an impartial evaluation that’s executed by somebody aside from Hydro-Québec,” Bernard stated in an interview. “Rising the resilience of the distribution community must be a precedence of the federal government. It’s not excessive sufficient on the agenda of preoccupations.”

Quebec’s state-owned electrical energy firm is dealing with contradictory calls for. It’s being requested to maintain residential charges low, generate ever greater dividends for the federal government and broaden its distribution community because the province goals to make its economic system carbon-neutral by 2050.

“We need to protect low charges however we additionally desire a dependable community. It’s a really troublesome steadiness to search out,” stated Pineau, whose new ebook, L’équilibre énergétique, focuses on the power transition. “Outages like these remind us that we now have to take care of our infrastructure, which has a price. Sadly, as a result of shoppers are placing loads of stress on minimizing price will increase, it’s troublesome for Hydro-Québec to place extra emphasis on preventive upkeep. These are the sort of bills that are likely to get pushed again.”

This month’s ice storm marked the third time in lower than a yr — following Might 2022’s “derecho” episode and a late December windstorm that disadvantaged greater than 640,000 properties of energy — that components of Quebec have been plunged into darkness for extended intervals.

Some areas fared worse than others. Montreal, which has about half of its distribution community buried, had lots of of hundreds of residents affected for days on finish after branches and full timber collapsed underneath the burden of the freezing rain. Neighbouring Westmount, which has greater than 70 per cent of its distribution community underground, suffered solely minor outages.

Hydro-Québec’s distribution community has seen its reliability deteriorate lately, Quebec auditor normal Guylaine Leclerc wrote in a December 2022 report that expressed concern over the utility’s capacity to forestall outages and change growing old infrastructure.

For instance, the common length of outages per buyer served rose 63 per cent between 2012 and 2021 — a determine that excludes outages resulting from main climate occasions.

With demand for electrical energy projected to leap 14 per cent by 2032, making the grid extra resilient is a necessity, specialists say.

The anticipated development in demand “will increase the stress on the electrical energy distribution community,” Leclerc wrote in her report.

“While you electrify, you rely extra on electrical energy on your power transition,” Mousseau stated. “That’s a difficulty as a result of we’re not prepared. There aren’t any plans for lowering the dangers of energy failures. How are we going to guard residents? For now, there aren’t any solutions.”

With 34,775 kilometres of put in high-voltage strains, Hydro-Québec operates the biggest energy transmission system in North America. Within the years following the ice storm of 1998, the corporate invested massively to shore up that community, which hyperlinks producing stations within the northern a part of the province and Labrador to city load centres.

Its medium-voltage distribution community, which delivers powers to properties and companies, is thrice as lengthy, spanning 121,000 kilometres — about 106,000 kilometres, or 88 per cent, of that are aerial, in response to Quebec’s auditor normal. Supporting the overhead strains are near 2 million wood poles, every with a helpful service life of fifty to 60 years. Many of the underground strains are in city areas.

9 years in the past, the provincial fee on power points urged that the burying of energy strains in densely populated areas develop into the norm. In its February 2014 report, it additionally known as for electrical distribution methods in any new residential, business or industrial growth that’s served by water and sewers to be buried.

Value is a key hurdle. Deploying an underground distribution community can price about $1 million per kilometre — about 10 instances as a lot as an aerial community, Hydro-Québec spokesperson Cendrix Bouchard stated.

Burying all of Hydro-Québec’s wires would most likely price about $100 billion, Power Minister Pierre Fitzgibbon stated in early April. That may exceed the worth of Hydro-Québec’s property, which totalled $89 billion as of 2022.

The $100 billion determine displays “a coverage of burying each line. Everyone understands that this gained’t occur,” Fitzgibbon advised the Montreal Gazette in a mid-April interview.

In any occasion, burying the ability strains isn’t any panacea.

One key drawback of underground strains is that service restoration instances after an outage are usually longer than with an aerial community, Hydro-Québec says. “Nevertheless, failures must be much less frequent,” Bouchard stated.

One other disadvantage is the problem of connecting new shoppers as soon as a community is underground.

“Buried strains are extra resistant however while you need to enhance the capability, it prices much more,” Pineau stated. “The issue is that we in Quebec have determined to occupy the land primarily based on city sprawl. While you select city sprawl, you want infrastructure that covers much more floor, which prices more cash. Counting on city sprawl is incompatible with burying the strains.”

Hydro-Québec’s 2022-24 Local weather Change Adaptation Plan, a 132-page doc printed in November, identifies 26 “motion areas” centred round design, operations, energy outages and employee well being and security however solely mentions burial of energy strains briefly.

To restrict the impression of utmost climate occasions, the doc recommends experimenting with burying sure sections of the distribution system “utilizing a brand new strategy requiring much less civil engineering work.”

Hydro-Québec has just lately been testing so-called “mild” burial strategies that decision for cables to be laid straight on a mattress of sand at a depth of 1 metre and coated with fencing. This contrasts with typical burial strategies, the place the ability cables are laid in concrete ducts.

Utilizing mild burial strategies additionally cuts the price of electrical and civil work in contrast with typical burial, in addition to the time required to finish the work, Hydro-Québec stated.

Two pilot initiatives had been carried out utilizing the brand new strategies. The primary one, which took two weeks, required burying 1.7 kilometres of strains in Gaspésie’s Mont-St-Pierre space in December 2021 at a price of $550,000. A second effort concerned burying 5.5 kilometres of strains in Parc de la Mauricie final fall at a price of $2.75 million, Bouchard stated.

Sadly, these strategies usually aren’t relevant to city areas as a result of they require particular circumstances to supply the specified outcomes — comparable to a restricted variety of buyer connections and a closely wooded space, Hydro-Québec says.

“This can be a method that works for areas with few clients,” Bouchard stated. “As soon as the road is buried, it’s troublesome to entry it so as to add a connection.”

In mild of the ice storm, ought to the federal government be proactive in forcing energy strains to be buried in city areas? Fitzgibbon thinks the thought is value contemplating.

“Hydro-Québec is conscious that when individuals excavate, as an illustration, to place pure gasoline strains or Web cables, there could be a logic in taking a look at burying” the distribution strains, he stated within the interview. “It’s clear that we should ask the query. In these instances, we must always consider the prices.”

Within the meantime, Quebec might begin by imposing underground energy strains each time a brand new neighbourhood is deliberate, stated the College of Ottawa’s Bernard.

“In new developments it’s comparatively easy to bury the strains,” Bernard stated. “Opening up streets in current areas prices some huge cash. You need to do it progressively.”

That gradual strategy is on show in Westmount, considered one of 10 Quebec municipalities that owns its electrical energy distributor.

Mayor Christina Smith says town has been burying energy strains each time roads are redone. She additionally credit “a reasonably lively pruning marketing campaign” for Westmount’s capacity to flee main outages following the ice storm.

“Individuals usually ask me what the advantages of Hydro-Westmount are, and that is one thing we’re all the time evaluating,” Smith stated in an interview. “Every time we redo a street, each time we do an entire rebuild, we all the time improve the hydro on the similar time. We get that executed block by block.”

In Montreal, Mayor Valérie Plante has stated she intends to sit down down with hearth division and Hydro-Québec officers to guage what when fallacious — and what labored nicely — throughout the storm.

For now, Montreal has a cope with Hydro-Québec to bury 4.5 kilometres of distribution strains a yr – paid for by town – till 2028, Bouchard stated. “This may seem to be a small quantity, however burying strains in an city setting the place every part is already constructed up requires loads of work,” he stated.

Finally, Fitzgibbon says Quebecers might want to determine whether or not they’re able to pay to make their electrical energy distribution community safer.

“Individuals need to ask, and rightly so: Are we prepared as a society to bear these prices in order that we develop into much less weak to energy outages? This can be a reliable query,” he stated.
