Long Island Power Authority (LIPA) and American Superconductor Corporation announced the operation of the worldÂ’s first high temperature superconductor (HTS) power transmission cable system in a commercial power grid.

The 138,000 volt (138 kV) system, which consists of three individual HTS power cable phases running in parallel, was energized on April 22 and is operating successfully in LIPAÂ’s Holbrook transmission right of way. The cable system, including six outdoor terminations for connection to LIPAÂ’s grid, was designed, manufactured and installed by Nexans, the worldwide leader in the cable industry.

The cable utilizes HTS wire produced by AMSC, which also is the prime contractor for the project. The 2,000-foot-long cable system is cryogenically cooled using a liquid nitrogen refrigeration system from Air Liquide.

The Department of Energy (DOE) previously funded $27.5 million of the $58.5 million total project cost, which advances the DepartmentÂ’s ongoing efforts, through the Office of Electricity Delivery and Energy Reliability, to modernize the NationÂ’s electricity delivery infrastructure.

The cable system contains hair-thin, ribbon-shaped HTS wires that conduct 150 times the electricity of similar sized copper wires. This power density advantage enables transmission-voltage HTS cables to utilize far less wire and yet conduct up to five times more power – in a smaller right of way – than traditional copper-based cables. When operated at full capacity, the new HTS cable system is capable of transmitting up to 574 megawatts (MW) of electricity, enough to power 300,000 homes.

HTS power cables are envisioned by the DOE as a component of a modern electricity superhighway – one that is free of bottlenecks and can readily transmit power to customers from remote generation sites, such as wind farms.

HTS cables conduct electricity with virtually no electrical losses, meaning more of the power generated at power plants gets to customers. Conventional power grids typically lose seven to 10 percent of power due to the inherent electrical resistance experienced with copper wires. The higher electrical efficiency of HTS cables provides a means to reduce carbon emissions while meeting the growing demand for electric power in the digital age.

Alternating current HTS power cables have inherently low impedance, which means they can draw power flow away from overtaxed conventional cables or overhead lines, thereby relieving network congestion. They can also be specially designed to have very low impedance (VLI) characteristics.

When deployed in strategic locations, VLI superconductor cables, such as the one currently operating in LIPAÂ’s power grid, can rapidly absorb additional power flows when conventional power grid components are damaged during electrical storms or other events. Because HTS cables are self-adjusting, they are expected to become core components of intelligent, more secure power networks.

LIPA is the third electric utility in the United States to have deployed an HTS cable system in its power grid. In the summer of 2006, National Grid and American Electric Power energized distribution voltage HTS power cable systems in Albany, New York and Columbus, Ohio, respectively.

At nearly half a mile in length, LIPAÂ’s HTS cable system is the longest of the three. It also is the first to operate at transmission voltages. After an initial operational period and following performance and economic reviews of the cable system, LIPA plans to retain the new superconductor cable as a permanent part of its grid.

In mid-2007, AMSC announced that it would lead the development of an extension of LIPAÂ’s HTS cable system. The new cable will be powered by AMSCÂ’s second generation (2G) HTS wire, branded as 344 superconductors. AMSC, who will again serve as the projectÂ’s prime contractor and wire supplier, has chosen Nexans as the cable manufacturer and Air Liquide as the provider of the cryogenics system.

The DOE plans to provide up to $9 million in cost sharing for the $18 million project.

Power outage update: 252,596 remain without electricity Wednesday

North Carolina Power Outages continue after Hurricane Florence, with Wilmington and Eastern Carolina facing flooding, storm damage, and limited access as Duke Energy crews and mutual aid work on restoration across affected counties.

 

Key Points

Outages after Hurricane Florence, with Wilmington and Eastern Carolina hardest hit as crews restore service amid floods.

✅ Over 250,000 outages statewide as of early Wednesday

✅ Wilmington cut off by flooding, hindering utility access

✅ Duke Energy and EMC crews conduct phased restoration

 

Power is slowly being restored to Eastern Carolina residents after Hurricane Florence made landfall near Wilmington on Friday, September 15, a scenario echoed by storm-related outages in Tennessee in recent days.

On Monday, more than half a million people remained without power across the state, a situation comparable to post-typhoon electricity losses in Hong Kong reported elsewhere.

As of Wednesday morning at 1am, the Dept. of Public Safety reports 252,596 total power outages in North Carolina, and utilities continue warning about copper theft hazards during restoration.

More than half of those customers are in Eastern Carolina.

More than 32,000 customers are without power in Carteret County and roughly 21,000 are without power in Onslow County.

In Craven County, roughly 15,000 people remain without power Wednesday morning.

Many of the state's outages are effecting the Wilmington area, where Florence made landfall and widespread flooding is still cutting off the city from outside resources, similar to how a fire-triggered outage in Los Angeles disrupted service regionally.

Heavy rain, strong winds and now flooded roadways have hindered power crews, challenges that utility climate adaptation aims to address while many of them have out-of-state or out-of-town help working to restore power to so many people.

Here's a breakdown of current outages by utility company:

Ontario pitches support for electric bills

Ontario CEAP Program provides one-time electricity bill relief for residential consumers via local utilities, supports low-income households, aligns with COVID-19 recovery rates, and complements time-of-use pricing options and the winter disconnection ban.

 

Key Points

A one-time electricity bill credit for eligible Ontario households affected by COVID-19, available via local utilities.

✅ Apply through your local distribution company or utility

✅ One-time credit for overdue electricity bills from COVID-19

✅ Complements TOU options, OER, and winter disconnection ban

 

Applications for the CEAP program for Ontario residential consumers has opened. Residential customers across the province can now apply for funding through their local distribution company/utility.

On June 1st, our government announced a suite of initiatives to support Ontario’s electricity consumers amid changes for electricity consumers during the pandemic, including a $9 million investment to support low-income Ontarians through the COVID-19 Energy Assistance Program (CEAP). CEAP will provide a one-time payment to Ontarians who are struggling to pay down overdue electricity bills incurred during the COVID-19 outbreak.

These initiatives include:

  • $9 million for the COVID-19 Energy Assistance Program (CEAP) to support consumers struggling to pay their energy bills during the pandemic. CEAP will provide one-time payments to consumers to help pay down any electricity bill debt incurred over the COVID19 period. Applications will be available through local utilities in the upcoming months;
  • $8 million for the COVID-19 Energy Assistance Program for Small Business (CEAP-SB) to provide support to businesses struggling with bill payments as a result of the outbreak; and
  • An extension of the Ontario Energy Board’s winter disconnection ban until July 31, 2020 to ensure no one is disconnected from their natural gas or electricity service during these uncertain times.


More information about applications for the CEAP for Small Business will be coming later this summer, as electricity rates are about to change across Ontario for many customers.

In addition, the government recently announced that it will continue the suspension of time-of-use (TOU) electricity rates and, starting on June 1, 2020, customers will be billed based on a new fixed COVID-19 hydro rate of 12.8 cents per kilowatt hour. The COVID-19 Recovery Rate, which some warned in analysis could lead to higher hydro bills will be in place until October 31, 2020.

Later in the pandemic, Ontario set electricity rates at the off-peak price until February 7 to provide additional relief.

“Starting November 1, 2020, our government has announced Ontario electricity consumers will have the option to choose between time-of-use and tiered electricity pricing plan, following the Ontario Energy Board’s new rate plan prices and support thresholds announcement. We are proud to soon offer Ontarians the ability to choose an electricity plan that best suits for their lifestyle,” said Jim McDonell, MPP for Stormont–Dundas–South Glengarry.

The government will continue to subsidize electricity bills by 31.8 per cent through the Ontario Electricity Rebate.

The government is providing approximately $5.6 billion in 2020-21 as part of its existing electricity cost relief programs and conservation initiatives such as the Peak Perks program to help ensure more affordable electricity bills for eligible residential, farm and small business consumers.

Working From Home Will Drive Up Electricity Bills for Consumers

Remote Work Energy Costs are rising as home offices and telecommuting boost electricity bills; utilities, broadband usage, and COVID-19-driven stay-at-home policies affect productivity, consumption patterns, and household budgets across the U.K. and Europe.

 

Key Points

Remote Work Energy Costs are increased household electricity and utility expenses from telecommuting and home office use.

✅ WFH shifts energy load from offices to households.

✅ Higher device, lighting, and heating/cooling usage drives bills.

✅ Broadband access gaps limit remote work equity.

 

Household electricity bills are set to soar, with rising residential electricity use tied to the millions of people now working at home to avoid catching the coronavirus.

Running laptops and other home appliances will cost consumers an extra 52 million pounds ($60 million) each week in the U.K., according to a study from Uswitch, a website that helps consumers compare the energy prices that utilities charge.

For each home-bound household, the pain to the pocketbook may be about 195 pounds per year extra, even as some utilities pursue pandemic cost-cutting to manage financial pressures.

The rise in price for households comes even as overall demand is falling rapidly in Europe, with wide swaths of the economy shut down to keep workers from gathering in one place, and the U.S. grid overseer issuing warnings about potential pandemic impacts on operations.

People stuck at home will plug in computers, lights and appliances when they’d normally be at the office, increasing their consumption.

With the Canadian government declaring a state of emergency due to the coronavirus, companies are enabling work-from-home structures to keep business running and help employees follow social distancing guidelines, and some utilities have even considered housing critical staff on site to maintain operations. However, working remotely has been on the rise for a while.

“The coronavirus is going to be a tipping point. We plodded along at about 10% growth a year for the last 10 years, but I foresee that this is going to really accelerate the trend,” Kate Lister, president of Global Workplace Analytics.

Gallup’s State of the Workplace 2017 study found that 43% of employees work remotely with some frequency. Research indicates that in a five-day workweek, working remotely for two to three days is the most productive. That gives the employee two to three days of meetings, collaboration and interaction, with the opportunity to just focus on the work for the other half of the week.

Remote work seems like a logical precaution for many companies that employ people in the digital economy, even as some federal agencies sparked debate with an EPA telework policy during the pandemic. However, not all Americans have access to the internet at home, and many work in industries that require in-person work.

According to the Pew Research Center, roughly three-quarters of American adults have broadband internet service at home. However, the study found that racial minorities, older adults, rural residents and people with lower levels of education and income are less likely to have broadband service at home. In addition, 1 in 5 American adults access the internet only through their smartphone and do not have traditional broadband access. 

Full-time employees are four times more likely to have remote work options than part-time employees. A typical remote worker is college-educated, at least 45 years old and earns an annual salary of $58,000 while working for a company with more than 100 employees, according to Global Workplace Analytics, and in Canada there is growing interest in electricity-sector careers among younger workers. 

New York, California and other states have enacted strict policies for people to remain at home during the coronavirus pandemic, which could change the future of work, and Canadian provinces such as Saskatchewan have documented how the crisis has reshaped local economies across sectors.

“I don’t think we’ll go back to the same way we used to operate,” Jennifer Christie, chief HR officer at Twitter, told CNBC. “I really don’t.”

South Australia rides renewables boom to become electricity exporter

Australia electricity grid transition is accelerating as renewables, wind, solar, and storage drive decentralised generation, emissions cuts, and NEM trade shifts, with South Australia becoming a net exporter post-Hazelwood closure and rooftop solar surging.

 

Key Points

Australia electricity shift to renewables, distributed generation and storage, cutting emissions, reshaping NEM flows.

✅ South Australia now exports power post-Hazelwood closure

✅ Rooftop solar is the fastest-growing NEM generation source

✅ Gas peaking and storage investments balance variable renewables

 

The politics may not change much, but Australia’s electricity grid is changing before our very eyes – slowly and inevitably becoming more renewable, more decentralised, and in step with Australia's energy transition that is challenging the pre-conceptions of many in the industry.

The latest national emissions audit from The Australia Institute, which includes an update on key electricity trends in the national electricity market, notes some interesting developments over the last three months.

The most surprising of those developments may be the South Australia achievement, which shows that since the closure of the Hazelwood brown coal generator in Victoria in March 2017, and as renewables outpacing brown coal in other markets, South Australia has become a net exporter of electricity, in net annualised terms.

Hugh Saddler, lead author of the study, notes that this is a big change for South Australia, which in 1999 and 2000, when it had only gas and local coal, used to import 30% of its electricity demand.

#google#

The fact that wholesale prices in South Australia were higher in other states – then, as they are now – has nothing to with wind and solar, but the fact that it has no low-cost conventional source and a peaky demand profile (then and now).

“The difference today is that the state is now taking advantage of its abundant resources of wind and solar radiation, and the new technologies which have made them the lowest cost sources of new generation, to supply much of its electricity requirements,” Saddler writes.

Other things to note about the flows between states is that Victoria was about equal on imports and exports with its three neighbouring states, despite the closure of Hazelwood. NSW continues to import around 10% of its needs from cheaper providers in Queensland.

Gas-fired generation had increased in the last year or two in South Australia as a result of the Northern closure, but is still below the levels of a decade ago.

But because it is expensive, this is likely to spur more investment in storage.

As for rooftop solar, Saddler notes that the share of residential solar in the grid is still relatively small but, despite excess solar risks flagged by distributors, it is the most steadily growing generation source in the NEM.

That line is expected to grow steadily. By 2040, or perhaps 2050, the share of distributed generation, which includes rooftop solar, battery storage and demand management, is expected to reach nearly half of all Australia’s grid demand.

Saddler, says, however, that the increase in large-scale solar over the last few months is a significant milestone in Australia’s transition towards clean electricity generation, mirroring trends in India's on-grid solar development seen in recent years. (See very top graph).

“Firstly, they are a concrete demonstration that the construction cost advantage, which wind enjoyed over solar until a year or two ago, is gone.

“From now on we can expect new capacity to be a mix of both technologies. Indeed, the Clean Energy Regulator states that it expects solar to account for half of all (new renewable) capacity by 2020, and the US is moving toward 30% from wind and solar as well.”

Alberta Carbon tax is gone, but consumer price cap on electricity will remain

Alberta Electricity Rate Cap stays despite carbon tax repeal, keeping the Regulated Rate Option at 6.8 cents/kWh. Levy funds cover market gaps as the UCP reviews NDP policies to maintain affordable utility bills.

 

Key Points

Program capping RRO power at 6.8 cents/kWh, using levy funds to offset market prices while the UCP reviews policy.

✅ RRO cap fixed at 6.8 cents/kWh for eligible customers

✅ Levy funds pay generators when market prices exceed the cap

✅ UCP reviewing NDP policies to ensure affordable rates

 

Alberta's carbon tax has been cancelled, but a consumer price cap on electricity — which the levy pays for — is staying in place for now.

June electricity rates are due out on Monday, about four days after the new UCP government did away with the carbon charge on natural gas and vehicle fuel.

Part of the levy's revenue was earmarked by the previous NDP government to keep power prices at or below 6.8 cents per kilowatt hour under new electricity rules set by the province.

"The Regulated Rate Option cap of 6.8 cents/kWh was implemented by the previous government and currently remains in effect. We are reviewing all policies put in place by the former government and will make decisions that ensure more affordable electricity rates for job-creators and Albertans," said a spokesperson for Alberta's energy ministry in an emailed statement.

Albertans with regulated rate contracts and all City of Medicine Hat utility customers only pay that amount or less, though some Alberta ratepayers have faced deferral-related arrears.

If the actual market price rises above that, the difference is paid to generators directly from levy funds, a buffer that matters as experts warn prices are set to soar later this year.

The government has paid more than $55 million to utilities over the past year ending in March 2019, due to that electricity price cap being in place.

Alberta Energy says the price gap program will continue, at least for the time being, amid electricity policy changes being considered.

Is Ontario embracing clean power?

Ontario Clean Energy Expansion signals IESO-backed renewables, energy storage, and low-CO2 power to meet EV-driven demand, offset Pickering nuclear retirement, and balance interim gas-fired generation while advancing grid reliability, decarbonization, and net-zero targets.

 

Key Points

Ontario Clean Energy Expansion plans to grow renewables and storage, manage short-term gas, and meet rising demand.

✅ IESO long-term procurements for renewables and storage

✅ Interim reliance on gas to replace Pickering capacity

✅ Targets align with net-zero grid reliability goals

 

After cancelling hundreds of renewable power projects four years ago, the Doug Ford government appears set to expand clean energy to meet a looming electricity shortfall across the province.

Recent announcements from Ontario Energy Minister Todd Smith and the province’s electric grid management agency suggest the province plans to expand low-CO2 electricity with new wind and solar plans in the long-term, even as it ramps up gas-fired power over the next five years.

The moves are in response to an impending electricity shortfall as climate-conscious drivers switch to electric vehicles, farmers replace field crops with greenhouses and companies like ArcelorMittal Dofasco in Hamilton switch from CO2-heavy manufacturing to electricity-based production. Forecasters predict Canada will need to double its power supply by 2050.

While Ontario has a relatively low-CO2 power system, the province’s electricity supply will be reduced in 2025 when Ontario Power Generation closes the 50-year-old Pickering nuclear station, now near the end of its operating life. This will remove 3,100 megawatts of low-CO2 generation, about eight per cent of the province’s 40,000-megawatt total.

The impending closure has created a difficult situation for the Independent Electricity System Operator (IESO), the provincial agency managing Ontario’s grid. Last year, it forecasted it would need to sharply increase CO2-polluting natural gas-fired power to avoid widespread blackouts.

This would mean drivers switching to electric vehicles or companies like Dofasco cutting CO2 through electrification would end up causing higher power system emissions.

It would also fly in the face of the federal government’s ambition to create a net-zero national electricity system by 2035, a critical part of Canada’s pledge to reduce CO2 emissions to zero by 2050.

Yet the Ford government has appeared reluctant to expand clean energy. In the 2018 election, clean electricity was a key issue as it appealed to anti-turbine voters in rural Ontario and cancelled more than 700 renewable energy contracts shortly after taking office, taking 400 megawatts out of the system.

But there are signs the government is having a change of heart. IESO recently released a list of 55 companies approved to submit bids for 3,500 megawatts of long-term electricity contracts starting between 2025 and 2027, and the energy minister has outlined a plan to address growing energy needs as well.

The companies include a variety of potential producers, ranging from Canadian and global renewable companies to local utilities and small startups. Most are renewable power or energy storage companies specializing in low- or zero-emission power. IESO plans additional long-term bid offerings in the future.

This doesn’t mean gas generation will be turned off. IESO will contract yearly production from existing gas plants until 2028 (the annual contract in 2023 will be for about 2,000 megawatts). As well, IESO has issued contracts to four gas-fired producers, a small wind company and a storage company to begin production of about 700 megawatts to boost gas plant output starting between 2024 and 2026.

While this represents an expansion of existing gas-fired generation, Smith has asked IESO to report on a gas moratorium, saying he doesn’t believe new gas plants will be needed over the long term.

The NDP and Greens criticized the government for relying on gas in the near term. But clean energy advocates greeted the long-term plans positively.

The IESO process “will contribute to a clean, reliable and affordable grid,” said the Canadian Renewable Energy Association.

Rachel Doran, director of policy and strategy at Clean Energy Canada, said in an email the potential gas generation moratorium “is an encouraging step forward,” although she criticized the “unfortunate decision to replace near-term nuclear power capacity with climate-change-causing natural gas.”

There will have to be a massive clean energy expansion to green Ontario’s grid well beyond what has been announced in recent days for Ontario to meet its future energy needs (think a doubling of Ontario’s current 40,000-megawatt capacity by 2050).

But these first steps hold promise that Ontario is at least starting on the path to that goal, rather than scrambling to keep the lights on with CO2-polluting natural gas.
