For more than 30 years, Doucette’s Market & Eatery has been a spot in Ingonish Seashore, N.S., where individuals can purchase groceries, order muffins and luxuriate in a meal or cup of coffee.
Between Cape Smokey Provincial Park and the Cape Breton Highlands, Doucette’s sits on the nook the place Ford Street meets the winding Cabot Path, approximately 120 metres up the street from the volunteer hearth station and C&J Computer systems. Should you pop into the shop, it’s probably house owners Ken and Trina Doucette will probably be round — as a result of they’re afraid to go away.
“It looks like the minute we depart city, the facility goes out,” Trina Doucette stated in an interview. “Everybody north of Smokey pretty much has a generator.”
Whereas Trina does not document when outages happen, she estimates that they lose power up to 20 occasions per yr, with every outage lasting between six and 10 hours.
“Some months we lose it so much, others by no means,” she stated.
Within the occasion of an outage, Ken and Trina need to be on the shop to modify power over to the generator, then re-rig their gear until the facility comes back. “The generator gained’t run every thing, so we have now to put on a freezer for some time, then shut that one off, put a special one on — just to keep all the things frozen,” Trina stated.
They manage to stay open during outages, retaining enterprise relatively regular. Nevertheless it’s tense because the shop might lose “hundreds of dollars’ value of inventory” when the facility goes out.
An evaluation of Nova Scotia Energy Inc. knowledge exhibits that Doucette’s Market isn’t an isolated case.

About 20 kilometres south of Doucette’s is a small group referred to as Wreck Cove. For years, it has had the province’s worst performing native energy circuits; it sits along the coastline and is uncovered.
Wreck Cove resident John Matthews made dropping energy look like a traditional inconvenience during an interview. When the lights go out, he calls Nova Scotia Power for their electricity-restoration estimate, then waits it out in his residence, which is provided with a generator and wood range.
Matthews stated he has never made a formal grievance to anyone.
Since November 2016, the facility firm has had to report its annual performance to the Nova Scotia Utility and Evaluation Board, the utility’s regulating body. In line with the 2018 efficiency standards annual report, there are several circuits in counties reminiscent of Lunenburg, Cumberland and Halifax, where Nova Scotia Power clients experienced more than 4 outages on average in 2018. In accordance with the same knowledge, clients in communities resembling Wreck Cove, Upper Musquodoboit and Upper Burlington, could possibly be with out energy for almost a day, if no more.
Since 2013, the number of circuits affected by a mean of at the very least 4 outages has declined, but the average quantity and period of outages across the whole province have increased.
Of observe, the circuit-performance knowledge that Nova Scotia Power studies to the utility board does not embrace vital outages brought on by climate. Those varieties of events are deemed major event days or excessive occasion days. In line with the 2018 efficiency requirements annual report, the “threshold for a serious event day is 165,849 CHI (customer hours of interruption) and the edge for an excessive occasion day is 1,109,000 CHI.”
In 2017, these thresholds have been 157,127 for major occasions days and 1,zero75,386 for extreme event days. That yr, there were four major occasion days and one extreme occasion day — the wind storm that hit Nova Scotia on Christmas Day 2017 and brought on 158,000 individual outages. News stories informed of half-cooked turkey dinners and families snuggling shut to one another in the course of the night time as a result of temperatures have been so cold.
In 2018, there have been six major event days and two extreme occasion days.
1 / 4 of one million houses
The newest excessive occasion day was Nov. 29, 2018, when approximately 250,000 houses and businesses — half of Nova Scotia Energy’s clients — misplaced power after a snow storm hit the northeastern part of the province. Information reviews stated it was the worst outage since hurricane Juan hit on Sep. 29, 2003, which prompted 300,000 outages.
The facility company stated the November 2018 storm saw wind and snow pull down one in every of 4 high-voltage transmission strains that carry electricity from three power crops in Cape Breton to mainland Nova Scotia. In information reviews, the corporate’s CEO, Karen Hutt, stated the three remaining strains might have completed the job, however the sagging wires went offline once they touched one another. The outage was compounded by another in Memramcook, N.B., the place a transmission line hyperlinks the New Brunswick and Nova Scotia power methods.
“We pay a number of the highest power charges within the nation; we anticipate that power. When it goes out … it wants to return again,” Progressive Conservative Leader Tim Houston was quoted saying.
“It says something fairly critical about grid maintenance as an entire,” Nova Scotia NDP Leader Gary Burrill stated on the time. “When we’ve this degree of infrastructure grid failure … why wouldn’t any regular individual assume, ‘Gosh, one thing is mistaken here.”‘
Premier Stephen McNeil deferred any questions relating to the Liberals’ response to the outage to the utility and evaluation board.
Matt Drover, director of regional operations for Nova Scotia Power, stated in an interview that clients’ expectations change every year, as society turns into extra reliant on electricity. He stated the corporate is doing every thing it may possibly to keep the lights on.

Based on Nova Scotia Power, outages are brought on by storms and excessive winds, snow or ice buildup on strains or gear, lightning, salt contamination, motorcar accidents involving their gear, gear failure, development and even animals. But the main cause is timber.
“We do have a province that is filled with timber,” Drover stated.
“The truth is there are loads of instances where we are unable to remove these timber. But we make prudent investments every year, to ensure we improve reliability for individuals.”
Drover stated that issues come up when Nova Scotia is hit with winds of a minimum of 90 km/h. Winds so robust can push timber onto power strains, which Drover says are often built by means of wooded areas. Heavy snow and ice may also fell timber.
The utility can’t control the weather, which, as a consequence of international local weather change, is turning into more severe. But one other challenge for Nova Scotia Energy is that they can’t function on personal property with out permission from the landowner.
“In lots of instances, clients need to maintain their timber, even when they comprehend it’s going to trigger an outage,” Drover stated.
“There isn’t a state of affairs the place a customer dropping energy is an effective information story for us. However in instances the place a land owner won’t give us permission to take away the tree, we’ve no prescriptive rights to go in there and be capable of remove it ourselves, until it poses a direct safety concern for the line.”
Safety considerations would include if a tree was about to fall on a line
Since 2010, legislation has been carried out to improve Nova Scotia’s electrical system. Michel Samson, the Liberal minister of power till 2017, stated in an interview that there were quite a few points that wanted to be addressed, so current legislation exhibits the provincial authorities enjoying catch-up.
Through the 2013 provincial electoral race, “Nova Scotia Energy was a scorching matter in Nova Scotia for all the flawed causes,” Samson stated.
Charges have been growing virtually on an annual basis, however reliability was also a problem — much more than it’s now. In accordance with Nova Scotia Power circuit knowledge, in 2013, clients alongside seven totally different circuits in Nova Scotia — together with a circuit in Spryfield — experienced a minimum of 10 outages on average. In 2013, there have been 33 circuits whose common outage period was at the least 12 hours.
In 2018, just one circuit in Nova Scotia averaged double-figure frequency and solely 17 circuits outage period averaged no less than 12 hours.
Shortly after the 2013 election, the provincial government handed the Electricity Reform Act, forcing a comprehensive evaluation of the province’s electrical energy system, together with a public consultation. The Division of Power report stated it consulted more than 1,300 Nova Scotians in 2014.
On Dec. 18, 2015, the Electrical energy Plan Implementation Act acquired royal assent. The rate stability plan stemmed from this invoice, allowing Nova Scotia Energy clients to know the precise annual improve of charges over a three-year period. Chapter 31 of the invoice tasked the utility board with creating reliability efficiency standards for the province’s electrical system, using metrics greatest fitted to Nova Scotia.
“There have been no standards on which to guage Nova Scotia Energy’s efficiency, when it got here to the reliability… and, extra importantly, restoration of energy when there had been an outage,” Samson stated.
The utility board consulted with London Economics Worldwide, a worldwide financial, monetary and strategic advisory firm specializing in power and infrastructure. In November 2016, the board confirmed the standards and metrics.
System reliability can be measured by the typical quantity and period of outages every buyer experiences in a yr, as well as the typical number and period of outages clients related to a selected circuit experience in a yr.
Based on Nova Scotia Energy, generating crops make electricity, which is then despatched to substations in communities throughout Nova Scotia. These substations rework the voltage from high to low and send it by way of “feeder” strains (circuits). From each substation stems a handful of circuits, which unfold out and each serve clients. Figuring out how many outages hit every circuit, and the way long they final, are crucial metrics for learning which clients are most affected. The opposite metrics give an general average.
Nova Scotia Power must restore a certain proportion of consumers inside 48 hours of a serious or extreme occasion day.
The utility board tracks that by measuring how shortly the facility firm restores electricity and the way it treats clients. In 2018, Nova Scotia Energy met these targets 87 per cent and 66 per cent of the time, respectively.
The utility must notify clients within four hours of the decision to open the Emergency Operations Centre, hold clients updated on restoration time as quickly as new estimates are made, and reply no less than 85 per cent of telephone calls within 45 seconds at the buyer care centre, throughout severe outage occasions. The polite disconnect name fee can’t exceed 10 per cent.
There are also performance standards for updating the stay outage map.
Nova Scotia is the only Atlantic province with such standards.
“Ought to the board determine that NSP has failed to satisfy its efficiency targets, the board might apply an administrative penalty up to an annual most of $1 million, which can’t be recovered from ratepayers,” the utility board stated in its 2016 performance standards determination.
Samson stated that everytime you’re deciding upon a superb, there’s a stability that must be found between deterrence and what an organization can fairly pay.
“Any shareholders of any company being informed they need to pay one million dollars completely aren’t going to be happy, and are going to demand accountability from management,” Samson stated.
Progressive Conservative Leader Tim Houston was vocal concerning the million-dollar figure being too low in the course of the second studying of the Electricity Plan Implementation Act. In an interview, Houston stated he believes Nova Scotia Energy needs to offer the perfect service attainable to its clients. His concern, nevertheless, is if there are conditions by which the utility opts to pay the fantastic as a result of it will be inexpensive than meeting the required normal.

“Corporations make monetary selections pushed — to no less than a point — by monetary influence,” Houston stated.
“If the intent of the legislation was to encourage sure exercise on the facility company, I don’t know if that positive would do it,” Houston stated.
“One million dollars is lots for me, and positively is for most people; in all probability not that a lot money for a corporation the dimensions of Nova Scotia Energy.”
Based on Emera Inc.’s 2018 annual report, Nova Scotia Energy had a internet revenue of roughly $131 million last yr. Emera is the facility company’s mother or father.
Houston has not seemed on the knowledge, but did say reliability appears to have improved.
Nova Scotia Power Inc. has a near monopoly, offering 95 per cent of the era, transmission and distribution of electrical energy in Nova Scotia. In response to Emera’s 2018 annual report, Nova Scotia Energy serves roughly 519,000 residential, business and industrial clients. There are six municipalities operating their own transmission and distribution methods, but they nonetheless purchase electrical energy from Nova Scotia Energy if they don’t generate their very own or purchase from unbiased power producers (most of whom provide wind power).
Nova Scotia Power should serve any customer in Nova Scotia, outdoors of the six municipal utilities. All clients — regardless of whether they’re in Ingonish Seashore or downtown Halifax — pay the same rates and are purported to have the same entry.
In accordance with 2018 circuit knowledge, a circuit in Wreck Cove had the worst performance of any within the province. The typical buyer linked to this circuit skilled greater than 17 outages, each lasting greater than 67 hours — almost three full days.
Lunenburg and Cumberland counties are often hit onerous, although Lunenburg was worse in 2018. When it comes to outage frequency, six of the province’s worst eight circuits have been in Lunenburg. Along those six circuits, the typical customer suffered between seven and nine outages, every lasting between 14.5 hours and slightly below 24 hours.
Circuits in Halifax Regional Municipality also had a tough yr. One in Porters Lake had the second-highest average of outages per customer in the province with 9, each lasting longer than 12 hours on common. Some urban areas, corresponding to Maple Road in downtown Dartmouth, skilled frequent outages. Clients linked to a circuit of the Maple Road substation experienced about five outages, every lasting greater than eight hours on average.

In response to a comparison of electrical energy costs carried out by Hydro Quebec in 2018, Nova Scotia Power clients pay the third-highest rates in Canada. Solely Saskatchewan and P.E.I. have larger residential charges.
In Nova Scotia, residential charges have increased by 1.7 per cent each of the last three years. As of Jan.1, 2019, the residential service base charge is $10.83 per thirty days, plus 15.6 cents per kilowatt hour.
Nova Scotia Energy’s residential clients using electric-based heating techniques or electric in-floor heating techniques permitted by the utility do have one other cost choice. This feature permits clients to pay less per kilowatt hour during non-peak demand occasions, non-winter months, weekends and statutory holidays, however the prices of electrical energy improve through the winter when demand is highest. The bottom cost is $18.82 per thirty days, while kilowatt hours value between eight.68 cents and 19.96 cents, relying on the time, day and month.
“Balancing the expectations of shoppers concerning NSP’s efficiency and the level of price increases can current a challenge to the board,” consultants London Economics Worldwide stated in their 2016 efficiency standards paper for the utility board.
The will for long-term fee stabilization and a reliable system “implies a pure limit on the overall degree of efficiency delivered by NSP,” it added.

Underground power strains
Many Nova Scotians marvel why Nova Scotia Energy doesn’t bury the facility strains to guard them from timber and storms. In January 2013, the Edison Electrical Institute up to date its research about burying power strains, Out of Sight, Out of Thoughts.
It found burying strains does enhance system reliability, but doesn’t end outages.
It removes the specter of falling vegetation, along with most weather-related outages, which would end in fewer outages. Nevertheless, underground strains would nonetheless be weak in areas which are susceptible to flooding. It’s additionally a lot more durable to seek out the reason for anoutage when all the things is underground.
“When there’s a failure, you need to pinpoint where it is,” stated Nova Scotia Energy’s Matt Drover. He added that, in contrast to with overhead power strains — where crews can comply with the circuit till they actually see the issue — underground floor strains require crews to go to each manhole until the outage is found.
Then there’s footing the bill.
In accordance with the Edison research, burying power strains could be 5 to 10 occasions costlier than putting in overhead poles. In 2019 Canadian dollars, the price of putting in overhead power strains can range from approximately $251,300 to $9.4 million per mile in rural areas, from $335,000 to $6.5 million per mile in suburban areas and from $545,000 to $15.9 million per mile in urban areas.
Distinction that with installing underground strains, which ranges from $2 million to $39 million per mile in rural areas, $3.three million to $43 million per mile in suburban areas and $5 million to $43.three million per mile in city areas.
Nova Scotia has 31,800 kilometres of power strains, of which about 45 kilometres are underground.
NSP says the typical value of installing underground strains is $1,000 per metre, $100,000 for each manhole and roughly $500,000 for a vault. The manholes are wanted to offer staff a protected entry to entry gear and the vault is put in for underground storage of kit like transformers and breakers.
Have been the province to transform its complete electrical system and go underground, a fast calculation exhibits the underground power cables alone would value almost $32 billion.
The higher costs are because of the supplies of underground cables, plus the planning, labour and time it takes to bury power strains. Drover stated that there’s a lot of rock to dig via in Nova Scotia and cement must be poured around the cables to stop erosion from the rock. This is able to improve costs as properly.
These costs do not embrace the need for more frequent alternative of the underground cables, since they don’t final as long as overhead poles and cables.
In response to estimates by Manitoba Hydro, underground cables can final between 30 to 70 years. Overhead picket poles can final 75 years, and overhead energy strains can last as long as 100 years.
Mohamed El-Hawary, an professional on electrical energy methods at Dalhousie University, says compact, densely populated areas reminiscent of Manhattan, New York are higher fitted to underground energy strains as a result of they will afford it.
Manhattan has an estimated population of 1.63 million, dwelling within about 37 square kilometres. Nova Scotia has a inhabitants of 953,869 and spans 55,284 square kilometres.
Finally, El-Hawary says, no matter steps are taken to make the system more dependable have to be cost-effective.
Because timber are the primary reason for outages within the province, Nova Scotia Power invests $20 million annually in the direction of trimming and eradicating timber.
Drover stated this could involve axing a tree utterly, simply slicing off certain branches, or spraying herbicide to stop future progress in areas the place timber have been torn down. He added that crews work on vegetation year-round, and focus primarily in areas of the province with poor reliability.
“It’s unimaginable to remove every tree in the province,” Drover stated. “So if we will’t handle reliability that means, then perhaps there are progressive ways that we will work with clients to ensure their power stays on when we’ve got an outage.”

The corporate additionally invests about $80 million yearly in system maintenance and upgrades. One example can be a pilot challenge on-going in Elmsdale, in Hants County, where they’re testing new Tesla know-how. A storage battery referred to as a Powerpack was installed in a neighbourhood substation and ten houses acquired an power storage Powerwall.
The Powerpack is fed power from intermittent renewable sources comparable to wind or solar, and might be charged or discharged at any time. The Powerwalls will routinely discharge in the occasion of an outage, providing back-up energy to the house. The Powerpack can provide power to any clients along the particular Elmsdale circuit, even those and not using a Powerwall.
NSP says one utilization state of affairs being tested is charging the battery when the wind blows, then discharging the Powerpack throughout peak load, when buyer demand is highest.
Anne and Mac Noble are two of the volunteers for the Elmsdale pilot venture. In an interview, Mac stated the facility has gone out a couple of occasions because the Powerwall was put in and the back-up provide instantly kicked in in order that they didn’t lose electrical energy.
“It’s so quick that it doesn’t even click the computer off,” he stated.
The battery lifetime of the Powerwall is determined by what number of issues are plugged into it. The Nobles have been utilizing electrical energy as normal during outages. One outage lasted seven hours in the fall and it solely used 15 per cent of the battery energy.
“But you don’t understand how long the facility goes to be off, so that you don’t do something terribly silly,” Mac stated.
Sensible meters coming
More quick system modifications will start later in 2019, as Nova Scotia Energy switches its clients to sensible meters. In response to the corporate, this can be a $133 million funding accepted by the utility and evaluation board. Installation is free for patrons.
“At the moment, with out sensible meters, the only approach we know the facility is out is that if individuals call in,” Drover stated. “Sensible meters will utterly revolutionize that.”
Based on Nova Scotia Power, both digital and analog meters use electrical energy fed from the service wire related to a customer’s residence or enterprise. The meter makes use of minimal electrical energy to operate and is absorbed as a part of Nova Scotia Energy’s operational costs. Sensible meters shall be powered in the same method.
The distinction, nevertheless, is sensible meters are outfitted with a personal wi-fi connection to the Nova Scotia Power system. This enables the utility to know precisely when a buyer’s power goes out, and allows them to read meters from a computer, somewhat than sending someone out for a visit each two months.
Drover says that Nova Scotia Power is among the last utilities to undertake sensible meters, which suggests they’ve discovered from other utilities.
In 2014, Hydro-Québec and Hydro One, in Ontario, launched investigations into unexplained increases in power bills shortly after sensible meters have been installed. That very same yr, the Saskatchewan government ordered SaskPower to remove 105,000 sensible meters after eight homes one way or the other caught hearth because of the units.
To keep away from those mishaps, Drover stated that they are going to be working intently with Measurement Canada, a federal agency chargeable for the accuracy of measuring units. As soon as put in, NSP will ship staff for the sensible meters’ initial readings.
On prime of potential malfunctions, Nova Scotia Energy will face anti-smart meter advocates comparable to No Sensible Meters In Nova Scotia, who declare that, on prime of elevated prices to clients, sensible meters present health and safety risks. They provide no proof to prove their claims.
Health Canada says that radiation from sensible meters doesn’t pose a public health danger. The exposure levels can be just like being uncovered to AM or FM radio alerts.
Clients can choose out of sensible meter set up — but at a worth. The utility board has set two choices: clients whose meters are at present learn each two months will move to 2 reads per yr, and pay $four per 30 days. Or, clients whose meters are read every month will proceed to have monthly reads, and pay a payment of $22 per thirty days.
That stated, Nova Scotia Power needs to apply to and receive approval from the utility board before charging opt-out charges. Clients won’t be charged till the province-wide sensible meter installation is full in late 2020.
Meanwhile, back in Ingonish Seashore, as Nova Scotia Power tries to seek out ways to make a extra reliable grid, Ken and Trina Doucette, the house owners of Doucette’s Market & Eatery, will proceed staying close to the shop. They’ll maintain their shop’s generator filled with fuel and anticipate the subsequent power outage.
