Maritime Link Subsea Cable enables HVDC grid interconnection across the Cabot Strait, linking Nova Scotia with Newfoundland and Labrador to import Muskrat Falls hydroelectric power and expand renewable energy integration and reliability.

Key Points

A 170-km HVDC subsea link connecting Nova Scotia and Newfoundland and Labrador for Muskrat Falls power and renewables

✅ 170-km HVDC subsea route across Cabot Strait

✅ Connects Nova Scotia and Newfoundland and Labrador grids

✅ Enables Muskrat Falls hydro and renewable energy trade

The longest sub-sea electricity cable in North America now connects Nova Scotia and Newfoundland and Labrador, according to the company behind the $1.7-billion Maritime Link project.  

The first of the project's two high-voltage power transmission cables was anchored at Point Aconi, N.S., on Sunday. 

The 170-kilometre long cable across the Cabot Strait will connect the power grids in the two provinces. The link will allow power to flow between the two provinces, as demonstrated by its first electricity transfer milestone, and bring to Nova Scotia electricity generated by the massive Muskrat Falls hydroelectric project in Labrador. 

Ultimately, the Maritime Link will help Nova Scotia reach the renewable energy goals set out by the federal government, said Rick Janega, the president and CEO of Emera Newfoundland and Labrador, whose subsidiary owns the Maritime Link.

"If not for the Maritime Link then really the province would not have the ability to meet those requirements because we're pretty much tapped out of all the hydro in province and all the wind generation without creating new interconnections like the Maritime Link," said Janega. 

Not everyone wanted the link 

Fishermen in Cape Breton had objected to the Maritime Link. They were concerned about how the undersea cable might affect fish in the area. 

The laying of the cable and other construction closed a three-kilometre long and 600-metre wide swath of ocean bottom to fishermen for the entire 2017 lobster season.  

But the company came to an agreement to compensate a group of 60 Cape Breton lobster and crab fishermen affected by the project this season. The terms of the compensation deal were not released. 

Long cable, big job

The transmission cable runs northwest of the Marine Atlantic ferry route between North Sydney, N.S., and Port aux Basques, N.L. 

Installation of the second cable is set to begin in June, a major step comparable to BC Hydro's Site C transmission milestone achieved recently. The entire link should be completed by late 2017 and should go into full service by January 2018.

"We're quite confident as soon as the Maritime Link is in service there will be energy transactions between Nova Scotia Power and Newfoundland Hydro. Both utilities have already identified opportunities to save money and exchange energy between the two provinces," said Janega.

That's two years before power is expected to flow from the Muskrat Falls hydro project. The Labrador-based power generating facility has been hampered by delays.

Those kinds of transmission project delays are expected for such a large project, said Janega, and won't stop the Maritime Link from being used. 

"With the Maritime Link going in service this year providing Nova Scotia the opportunity that it needs to be able to reach carbon reductions and to adapt to climate change and to increase renewable energy content and we're very pleased to be at this state today," said Janega.

Downed Power Line Vehicle Safety: Follow stay-in-the-car protocol, call 911, avoid live wires and utility poles, and use the bunny hop to escape only for fire. Electrical hazards demand emergency response caution.

Key Points

Stay in the car, call 911, and use a bunny hop escape only if fire threatens during downed power line incidents.

✅ Stay in vehicle; tell bystanders to keep back and call 911.

✅ Exit only for fire; jump clear and bunny hop away.

✅ Treat all downed lines as live; avoid paths to ground.

Ameren Illinois and Safe Electricity are urging the public to stay in their cars and call 911 in the event of an accident involving a power pole that brings down power lines on or around the car.

In a media simulation Tuesday at the Ameren facility on West Lafayette Avenue, Ameren Illinois employees demonstrated the proper way to react if a power line has fallen on or around a vehicle, as some utilities consider on-site staffing measures during outbreaks. Although the situation might seem rare, Illinois motorists alone hit 3,000 power poles each year, said Krista Lisser, communications director for Safe Energy.

“We want to get the word out that, if you hit a utility pole and a live wire falls on your vehicle, stay in your car,” Lisser said. “Our first reaction is we panic and think we need to get out, a sign of the electrical knowledge gap many people have. That’s not the case, you need to stay in because, when that live wire comes down, electricity is all around you. You may not see it, it may not arc, it may not flash, you may not know if there’s electricity there.”

Should someoneinvolved in such an accident see a good Samaritan attempting to help, he should try to tell the would-be rescuer to stay back to prevent injury to the Samaritan, Ameren Illinois Communications Executive Brian Bretsch said.

“We have seen instances where someone comes up and wants to help you,” Bretsch said. “You want to yell, ‘Please stay away from the vehicle. Everyone is OK. Please stay away.’ You’ll see … instances every now and then where the Samaritan will come up, create that path to ground and get injured, and there are also climbers seeking social media glory who put themselves at risk.”

The only instance in which one should exit a car in the vicinity of a downed wire is if the vehicle is on fire and there is no choice but to exit. In that situation, those in the car should “bunny hop” out of the car by jumping from the car without touching the car and the ground at the same time, Bretsch and Lisser said.

After the initial jump, those escaping the vehicle should continue jumping with both feet together and hands tucked in and away from danger until they are safely clear of the downed wire.

It’s important for everyone to be informed, because an encounter with a live wire could easily result in serious injury, as in the Hydro One worker injury case, or death, Lisser said.

“They’re so close to our roads, especially in our rural communities, that it’s quite a common occurrence,” Lisser said. “Just stay away from (downed lines), especially after storms and amid grid oversight warnings that highlight reliability risks … Always treat a downed line as a live wire. Never assume the line is dead.”

Minnesota Electric Cooperatives are driving grid innovation with smart meters, time-of-use pricing, demand response, and energy storage, including iron-air batteries, to manage peak loads, integrate wind and solar, and cut costs for rural members.

Key Points

Member-owned utilities piloting load management, meters, and storage to integrate wind and solar, cutting peak demand.

✅ Time-of-use pricing pilots lower bills and shift peak load.

✅ Iron-air battery tests add multi-day, low-cost energy storage.

✅ Smart meters enable demand response across rural co-ops.

Minnesota electric cooperatives have quietly emerged as laboratories for clean grid innovation, outpacing investor-owned utilities on smart meter installations, time-based pricing pilots, and experimental battery storage solutions.

“Co-ops have innovation in their DNA,” said David Ranallo, a spokesperson for Great River Energy, a generation and distribution cooperative that supplies power to 28 member utilities — making it one of the state’s largest co-op players.

Minnesota farmers helped pioneer the electric co-op model more than a century ago, similar to modern community-generated green electricity initiatives, pooling resources to build power lines, transformers and other equipment to deliver power to rural parts of the state. Today, 44 member-owned electric co-ops serve about 1.7 million rural and suburban customers and supply almost a quarter of the state’s electricity.

Co-op utilities have by many measures lagged on clean energy. Many still rely on electricity from coal-fired power plants. They’ve used political clout with rural lawmakers to oppose new pollution regulations and climate legislation, and some have tried to levy steep fees on customers who install solar panels.

Where they are emerging as innovators is with new models and technology for managing electric grid loads — from load-shifting water heaters to a giant experimental battery made of iron. The programs are saving customers money by delaying the need for expensive new infrastructure, and also showing ways to unlock more value from cheap but variable wind and solar power.

Unlike investor-owned utilities, “we have no incentive to invest in new generation,” said Darrick Moe, executive director of the Minnesota Rural Electric Association. Curbing peak energy demand has a direct financial benefit for members.

Minnesota electric cooperatives have launched dozens of programs, such as the South Metro solar project, in recent years aimed at reducing energy use and peak loads, in particular. They include:

Cost calculations are the primary driver for electric cooperatives’ recent experimentation, and a lighter regulatory structure and evolving electricity market reforms have allowed them to act more quickly than for-profit utilities.

“Co-ops and [municipal utilities] can act a lot more nimbly compared to investor-owned utilities … which have to go through years of proceedings and discussions about cost-recovery,” said Gabe Chan, a University of Minnesota associate professor who has researched electric co-ops extensively. Often, approval from a local board is all that’s required to launch a venture.

Great River Energy’s programs, which are rebranded and sold through member co-ops, yielded more than 101 million kilowatt-hours of savings last year — enough to power 9,500 homes for a year.

Beyond lowering costs for participants and customers at large, the energy-saving and behavior-changing programs sometimes end up being cited as case studies by larger utilities considering similar offerings. Advocates supporting a proposal by the city of Minneapolis and CenterPoint Energy to allow residents to pay for energy efficiency improvements on their utility bills through distributed energy rebates used several examples from cooperatives.

Despite the pace of innovation on load management, electric cooperatives have been relatively slow to transition from coal-fired power. More than half of Great River Energy’s electricity came from coal last year, and Dairyland Power, another major power wholesaler for Minnesota co-ops, generated 70% of its energy from coal. Meanwhile, Xcel Energy, the state’s largest investor-owned utility, has already reduced coal to about 20% of its energy mix.

The transition to cleaner power for some co-ops has been slowed by long-term contracts with power suppliers that have locked them into dirty power. Others have also been stalled by management or boards that have been resistant to change. John Farrell, director of the Institute for Local Self-Reliance’s Energy Democracy program, said generalizing co-ops is difficult. 

“We’ve seen some co-ops that have got 75-year contracts for coal, that are invested in coal mines and using their newsletter to deny climate change,” he said. “Then you see a lot of them doing really amazing things like creating energy storage systems … and load balancing [programs], because they are unique and locally managed and can have that freedom to experiment without having to go through a regulatory process.”

Great River Energy, for its part, says it intends to reach 54% renewable generation by 2025, while some communities, like Frisco, Colorado, are targeting 100% clean electricity by specific dates. Its members recently voted to sell North Dakota’s largest coal plant, but the arrangement involves members continuing to buy power from the new owners for another decade.

The cooperative’s path to clean power could become clearer if its experimental iron-air battery project is successful. The project, the first of its kind in the country, is expected to be completed by 2023.

DTEK Rotterdam+ price-fixing case scrutinizes alleged collusion over coal-based electricity tariffs in Ukraine, with NABU probing NERC regulators, market manipulation, consumer overpayment, and wholesale pricing tied to imported coal benchmarks.

Key Points

NABU probes alleged DTEK-NERC collusion to inflate coal power tariffs via Rotterdam+; all suspects deny wrongdoing.

✅ NABU alleges tariff manipulation tied to coal import benchmarks.

✅ Four DTEK execs and four NERC officials reportedly charged.

✅ Probe centers on 2016-2017 overpayments; defendants contest.

Two more executives of DTEK, Ukraine’s largest private power and coal producer and recently in energy talks with Octopus Energy, have been charged in a criminal case on August 14 involving an alleged conspiracy to fix electricity prices with the state energy regulator, Interfax reported.

They are Ivan Helyukh, the CEO of subsidiary DTEK Grid, which operates as Ukraine modernizes its network alongside global moves toward a smart electricity grid, and Borys Lisoviy, a top manager of power generation company Skhidenergo, according to Kyiv-based Concorde Capital investment bank.

Ukraine’s Anti-Corruption Bureau (NABU) alleges that now four DTEK managers “pressured” and colluded with four regulators at the National Energy and Utilities Regulatory Commission to manipulate tariffs on electricity generated from coal that forced consumers to overpay, reflecting debates about unjustified profits in the UK, $747 million in 2016-2017.

DTEK allegedly benefited $560 million in the scheme.

All eight suspects are charged with “abuse of office” and deny wrongdoing, similar to findings in a B.C. Hydro regulator report published in Canada.

There is “no legitimate basis for suspicions set out in the investigation,” DTEK said in an August 8 statement.

Suspect Dmytro Vovk, the former head of NERC, dismissed the investigation as a “wild goose chase” on Facebook.

In separate statements over the past week, DTEK said the managers who are charged have prematurely returned from vacation to “fully cooperate” with authorities in order to “help establish the truth.”

A Kyiv court on August 14 set bail at $400,000 for one DTEK manager who wasn’t named, as enforcement actions like the NT Power penalty highlight regulatory consequences.

The so-called Rotterdam+ pricing formula that NABU has been investigating since March 2017, similar to federal scrutiny of TVA rates, was in place from April 2016 until July of this year.

It based the wholesale price of electricity by Ukrainian thermal power plants on coal prices set in the Rotterdam port plus delivery costs to Ukraine.

NABU alleges that at certain times it has not seen documented proof that the purchased coal originated in Rotterdam, insisting that there was no justification for the price hikes, echoing issues around paying for electricity in India in some markets.

Ukraine started facing thermal-coal shortages after fighting between government forces and Russia-backed separatists in the eastern part of the country erupted in April 2014. A vast majority of the anthracite-coal mines on which many Ukrainian plants rely are located on territory controlled by the separatists.

Overnight, Ukraine went from being a net exporter of coal to a net importer and started purchasing coal from as far away as South Africa and Australia.

Calgary EV Charging for Apartments and Condos streamlines permitting for multi-unit dwellings, guiding condo boards and property managers to install EV charging stations, expand infrastructure, and advance sustainability with cleaner air and lower emissions.

Key Points

A Calgary program simplifying permits and guidance to add EV charging stations in multi-unit residential buildings.

✅ Streamlined permitting for condo boards and property managers

✅ Technical assistance to install EV charging stations

✅ Boosts property value and reduces emissions citywide

As the demand for electric vehicles (EVs) continues to rise, and as national EV targets gain traction, Calgary is taking significant strides to enhance its charging infrastructure, particularly in apartment and condominium complexes. A recent initiative has been introduced to facilitate the installation of EV charging stations in these residential buildings, addressing a critical barrier for potential EV owners living in multi-unit dwellings.

The Growing EV Market

Electric vehicles are no longer a niche market; they have become a mainstream option for many consumers. As of late 2023, EV sales have surged, with projections indicating that the trend will only continue. However, a significant challenge remains for those who live in apartments and condos, where high-rise charging can be a mixed experience and the lack of accessible charging stations persists. Unlike homeowners with garages, residents of multi-unit dwellings often rely on public charging infrastructure, which can be inconvenient and limiting.

The New Initiative

In response to this growing concern, the City of Calgary has launched a new initiative aimed at easing the process of installing EV chargers in apartment and condo buildings. This program is designed to streamline the permitting process, reduce red tape, and provide clear guidelines for property managers and condo boards, similar to strata installation rules adopted in other jurisdictions to ease installations.

The initiative includes various measures, such as providing technical assistance and resources to building owners and managers. By simplifying the installation process, the city hopes to encourage more residential complexes to adopt EV charging stations. The initiative also emphasizes practical support, such as providing technical assistance, including condo retrofit guidance, and resources to building owners and managers. This is a significant step towards creating an eco-friendly urban environment and meeting the growing demand for sustainable transportation options.

Benefits of the Initiative

The benefits of this initiative are manifold. Firstly, it supports Calgary's broader climate goals by promoting electric vehicle adoption. As more residents gain access to charging stations, the city can expect a corresponding reduction in greenhouse gas emissions, contributing to cleaner air and a healthier urban environment.

Additionally, providing charging infrastructure can enhance property values. Buildings equipped with EV chargers become more attractive to potential tenants and buyers who prioritize sustainability. As the market for electric vehicles expands, properties that offer charging facilities are likely to see increased demand, making them a sound investment for landlords and developers.

Overcoming Challenges

While this initiative marks a positive step forward, there are still challenges to address. Property managers and condo boards may face initial resistance from residents who are uncertain about the costs associated with installing and maintaining EV chargers, though rebates for home and workplace charging can offset upfront expenses and ease adoption. Clear communication about the long-term benefits, including potential energy savings and the value of sustainable living, will be essential in overcoming these hurdles.

Furthermore, the city will need to ensure that the installation of EV chargers is done in a way that is equitable and inclusive. This means considering the needs of all residents, including those who may not own an electric vehicle but would benefit from a greener community.

Looking Ahead

As Calgary moves forward with this initiative, it sets a precedent for other cities, as seen in Vancouver's EV-ready policy, facing similar challenges in promoting electric vehicle adoption. By prioritizing charging infrastructure in multi-unit residential buildings, Calgary is taking important steps towards a more sustainable future.

In conclusion, the push for EV charging stations in apartments and condos is a critical move for Calgary. It reflects a growing recognition of the role that urban planning and infrastructure play in supporting the transition to electric vehicles, which complements corridor networks like the BC Electric Highway for intercity travel. With the right support and resources, Calgary can pave the way for a greener, more sustainable urban landscape that benefits all its residents. As the city embraces this change, it will undoubtedly contribute to a broader shift towards sustainable living, ultimately helping to combat climate change and improve the quality of life for all Calgarians.

California Public Safety Power Shutoffs highlight wildfire prevention as PG&E outages disrupt schools, businesses, and rural communities, driving generator use, economic hardship, and emergency preparedness across Northern California during high-wind events.

Key Points

Utility outages to reduce wildfire risk during extreme winds, impacting homes and businesses in high-risk California.

✅ PG&E cuts power during high winds to prevent wildfires

✅ Costs rise for generators, fuel, batteries, and spoiled food

✅ Rural, low-income communities face greater economic losses

The intentional blackout by California’s largest utility this week put Forest Jones out of work and his son out of school. On Friday morning Mr. Jones, a handyman and single father, sat in his apartment above a tattoo parlor waiting for the power to come back on and for school to reopen.

“I’ll probably lose $400 or $500 dollars because of this,” said Mr. Jones, who lives in the town of Paradise, which was razed by fire last year and is slowly rebuilding. “Things have been really tough up here.”

Millions of people were affected by the blackout, which spanned the outskirts of Silicon Valley to the forests of Humboldt County near the Oregon border. But the outage, which the power company said was necessary to reduce wildfire risk across the region, also drew a line between those who were merely inconvenienced and those who faced a major financial hardship.

To have the lights on, the television running and kitchen appliances humming is often taken for granted in America, even as U.S. grid during coronavirus questions persisted. During California’s blackout it became an economic privilege.

The economic impacts of the shut-off were especially acute in rural, northern towns like Paradise, where incomes are a fraction of those in the San Francisco Bay Area.

Both wealthy and poorer areas were affected by the blackout but interviews across the state suggested that being forced off the grid disproportionately hurt the less affluent. One family in Humboldt County said they had spent $150 on batteries and water alone during the shutdown.

“To be prepared costs money,” Sue Warhaftig, a massage therapist who lives in Mill Valley, a wealthy suburb across the Golden Gate Bridge from San Francisco. Ms. Warhaftig spent around two days without electricity but said she had been spared from significant sacrifices during the blackout.

She invested in a generator to keep the refrigerator running and to provide some light. She cooked in the family’s Volkswagen camper van in her driveway. At night she watched Netflix on her phone, which she was able to charge with the generator. Her husband, a businessman, is in London on a work trip. Her two sons, both grown, live in Southern California and Seattle.

“We were inconvenienced but life wasn’t interrupted,” Ms. Warhaftig said. “But so many people’s lives were.

Pacific Gas & Electric restored power to large sections of Northern California on Friday, including Paradise, where the electricity came back on in the afternoon. But hundreds of thousands of people in other areas remained in the dark. The carcasses of burned cars still littered the landscape around Paradise, where 86 people died in the Camp Fire last year, some of them while trying to escape.

Officials at power company said that by Saturday they hoped to have restored power to 98 percent of the customers who were affected.

The same dangerous winds that spurred the shut-off in Northern California have put firefighters to work in the south. The authorities in Los Angeles County ordered the evacuation of nearly 100,000 people on Friday as the Saddleridge Fire burned nearly 5,000 acres and destroyed 25 structures. The Sandalwood Fire, which ignited Thursday in Riverside County, had spread to more than 800 acres and destroyed 74 structures by Friday afternoon.

While this week’s outage was the first time many customers in Northern California experienced a deliberate power shut-off, residents in and around Paradise have had their power cut four times in recent months, residents say.

Many use a generator, but running one has become increasingly expensive with gasoline now at more than $4 a gallon in California.

On Friday, Dennis and Viola Timmer drove up the hill to their home in Magalia, a town adjacent to Paradise, loaded with $102 dollars of gasoline for their generators. It was their second gasoline run since the power went out Tuesday night.

The couple, retired and on a fixed income after Mr. Timmer’s time in the Navy and in construction, said the power outage had severely limited their ability to do essential tasks like cooking, or to leave the house.

“You know what it feels like? You’re in jail,” said Ms. Timmer, 72. “You can’t go anywhere with the generators running.”

Since the generators are not powerful enough to run heat or air conditioning, the couple slept in their den with an electric space heater.

“It’s really difficult because you don’t have a normal life,” Ms. Timmer said. “You’re trying to survive.”

To be sure, the shutdown has affected many people regardless of economic status, and similar disruptions abroad, like a London power outage that disrupted routines, show how widespread such challenges can be. The areas without power were as diverse as the wealthy suburbs of Silicon Valley, the old Gold Rush towns of the Sierra Nevada, the East Bay of San Francisco and the seaside city of Arcata.

Ms. Cahn’s cellphone ran out of power during the blackout and even when she managed to recharge it in her car cell service was spotty, as it was in many areas hit by the blackout.

Accustomed to staying warm at night with an electric blanket, Ms. Cahn slept under a stack of four blankets.

“I’m doing what I have to do which is not doing very much,” she said.

Further south in Marin City, Chanay Jackson stood surrounded by fumes from generators still powering parts of the city.

She said that food stamps were issued on the first of the month and that many residents who had to throw away food were out of luck.

“They’re not going to issue more food stamps just because the power went out,” Ms. Jackson said. “So they’re just screwed until next month.”

Strong winds have many times in the past caused power lines to come in contact with vegetation, igniting fires that are then propelled by the gusts, and hurricanes elsewhere have crippled infrastructure with Louisiana grid rebuild after Laura according to state officials. This was the case with the Camp Fire.

Since higher elevations had more extreme winds many of the neighborhoods where power was turned off this week were in hills and canyons, including in the Sierra Nevada.

The shut-off, which by one estimate affected a total of 2.5 million people, has come under strong criticism by residents and politicians, and warnings from Cal ISO about rolling blackouts as the power grid strained. The company’s website crashed just as customers sought information about the outage. Gov. Gavin Newsom called it unacceptable. But his comments were nuanced, criticizing the way the shut-off was handled, not the rationale for it. Mr. Newsom and others said the ravages of the Camp Fire demanded preventive action to prevent a reoccurrence.

Yet the calculus of trying to avoid deadly fires by shutting off power will continue to be debated as California enters its peak wildfire season, even as electricity reliability during COVID-19 was generally maintained for most consumers.

In the city of Grass Valley, Matthew Gottschalk said he and his wife realized that a generator was essential when they calculated that they had around $500 worth of food in their fridge.

“I don’t know what we would have done,” said Mr. Gottschalk, whose power went out Tuesday night.

His neighbors are filling coolers with ice. Everyone is hoping the power will come back on soon.

“Ice is going to run out and gas is going to run out,” he said.
