Poland will spend 5 billion zlotys ($1.55 billion) over the next few years to meet its renewables target under the European Union's strategy to combat global warming, Environment Minister Maciej Nowicki said.

The 27-nation EU has undertaken to produce 20 percent of its total energy from renewable sources by 2020. Within that plan, Poland is only committed to securing 15 percent from renewables by 2020.

At present, renewables account for some 7 percent of power production in the biggest ex-communist EU member state and analysts say the goal may prove too ambitious.

Green industry lobbies say the development of green industry is stalled due to a lack of money and also an outdated power transmission network and unadjusted laws.

"I have calculated that over the next years we will support this industry with more than 5 billion zlotys. It's a lever to increase the value of the whole renewable energy market in Poland to some 15 billion zlotys," Nowicki said.

Poland's environment protection fund (NFOS) will provide 1.5 billion of that sum, regional authorities another 1 billion and more than 2.5 billion will come from EU funds, Nowicki said.

"I think we are easily able to achieve the 15 percent target by 2020 and this 5 billion zlotys could even push us up to 20 percent," he told Reuters in an interview.

Poland depends on polluting coal for more than 90 percent of its energy needs. Official statistics show more than 43 percent of Poland's power plants were constructed more than 30 years ago. Another 37 percent are between 20 and 30 years old.

In a move aimed at reducing Poland's reliance on coal, Warsaw wants to build at least one nuclear power plant by 2020.

"Poland has to renew at least 50 percent of its capacity between 2010 and 2020," Nowicki said.

"Even if two nuclear power plants are constructed by 2022, or 2023 — because the 2020 looks unlikely now — they will provide only some 10-15 percent of electricity for the country. So nuclear energy is... not a remedy for all our needs."

Poland hopes to start selling its surplus Kyoto carbon emissions this summer after introducing a new law and wants to sell 100 million CO2 permits by year-end, Nowicki said.

Under the Kyoto Protocol, signatory nations that are comfortably below their greenhouse gas emissions targets can sell excess emissions rights, called Assigned Amount Units (AAUs), to nations that are struggling to meet their targets.

But Poland, which has signed preliminary deals with Ireland, Japan and the World Bank, now lacks a law to finalize the deals.

"A bill is now being worked on in parliament. We are also continuing talks with many partners on this," Nowicki said.

"I hope we will be able to start signing the deals in the summer. My goal is to sell at least 100 million credits and it seems we are able to achieve that this year."

Nowicki declined to name the possible buyers or give the value of the potential deals.

Many polluting power plants in Poland were closed after the fall of communism in 1989. The surplus AAUs result from economic restructuring rather than investment in clean energy.

Americans aren't just blocking our oil pipelines, now they're fighting Hydro-Quebec's clean power lines

Champlain Hudson Power Express connects Hydro-Québec hydropower to the New York grid via a 1.25 GW high voltage transmission line, enabling renewable energy imports, grid decarbonization, storage synergy, and reduced fossil fuel generation.

 

Key Points

A 1.25 GW cross-border transmission project delivering Hydro-Québec hydropower to New York City to displace fossil power.

✅ 1.25 GW buried HV line from Quebec to Astoria, Queens

✅ Supports renewable imports and grid decarbonization in NYC

✅ Enables two-way trade and reservoir storage synergy

 

Last week, Quebec Premier François Legault took to Twitter to celebrate after New York State authorities tentatively approved the first new transmission line in three decades, the Champlain Hudson Power Express, that would connect Quebec’s vast hydroelectric network to the northeastern U.S. grid.

“C’est une immense nouvelle pour l’environnement. De l’énergie fossile sera remplacée par de l’énergie renouvelable,” he tweeted, or translated to English: “This is huge news for the environment. Fossil fuels will be replaced by renewable energy.”

The proposed construction of a 1.25 gigawatt transmission line from southern Quebec to Astoria, Queens, known as the Champlain Hudson Power Express, ties into a longer term strategy by Hydro Québec: in the coming decade, as cities such as New York and Boston look to transition away from fossil fuel-generated electricity and decarbonize their grids, Hydro-Québec sees opportunities to supply them with energy from its vast network of 61 hydroelectric generating stations and other renewable power, as Quebec has closed the door on nuclear power in recent years.

Already, the provincial utility is one of North America’s largest energy producers, generating $2.3 billion in net income in 2020, and planning to increase hydropower capacity over the near term. Hydro-Quebec has said it intends to increase exports and had set a goal of reaching $5.2 billion in net income by 2030, though its forecasts are currently under review.

But just as oil and gas companies have encountered opposition to nearly every new pipeline, Hydro-Québec is finding resistance as it seeks to expand its pathways into major export markets, which are all in the U.S. northeast. Indeed, some fossil fuel companies that would be displaced by Hydro-Québec are fighting to block the construction of its new transmission lines.

“Linear projects — be it a transmission line or a pipeline or highway or whatever — there’s always a certain amount of public opposition,” Gary Sutherland, director of strategic affairs and stakeholder relations for Hydro-Québec, told the Financial Post, “which is a good thing because it makes the project developer ask the right questions.”

While Sutherland said he isn’t expecting opposition to the line into New York, he acknowledged Hydro-Québec also didn’t fully anticipate the opposition encountered with the New England Clean Energy Connect, a 1.2 gigawatt transmission line that would cost an estimated US$950 million and run from Quebec through Maine, eventually connecting to Massachusetts’ grid.

In Maine, natural gas and nuclear energy companies, which stand to lose market share, and also environmentalists, who oppose logging through sensitive habitat, both oppose the project.

In August, Maine’s highest court invalidated a lease for the land where the lines were slated to be built, throwing permits into question. Meanwhile, Calpine Corporation and Vistra Energy Corp., both Texas-based companies that operate natural gas plants in Maine, formed a political action committee called Mainers for Local Power. It has raised nearly US$8 million to fight the transmission line, according to filings with the Maine Ethics Commission.

Neither Calpine nor Vistra could be reached for comment by the time of publication.

“It’s been 30 years since we built a transmission line into the U.S. northeast,” said Sutherland. “In that time we have increased our exports significantly … but we haven’t been able to build out the corresponding transmission to get that energy from point A to point B.”

Indeed, since 2003, Hydro-Québec’s exports outside the province have grown from roughly two terrawatts per year to more than 30 terrawatts, including recent deals with NB Power to move more electricity into New Brunswick. The provincial utility produces around 210 terrawatts annually, but uses less than 178 terrawatts in Quebec.

Linear projects — be it a transmission line or a pipeline or highway or whatever — there’s always a certain amount of public opposition

In Massachusetts, it has signed contracts to supply 9.4 terrawatts annually — an amount roughly equivalent to 8 per cent of the New England region’s total consumption. Meanwhile, in New York, Hydro-Québec is in the final stages of negotiating a 25-year contract to sell 10.4 terawatts — about 20 per cent of New York City’s annual consumption.

In his tweets, Legault described the New York contract as being worth more than $20 billion over 25 years, although Hydro Québec declined to comment on the value because the contract is still under negotiation and needs approval by New York’s Public Services Commission — expected by mid-December.

Both regions are planning to build out solar and wind power to meet their growing clean energy needs and reach ambitious 2030 decarbonization targets. New York has legislated a goal of 70 per cent renewable power by that time, while Massachusetts has called for a 50 per cent reduction in emissions in the same period.

According to a 2020 paper titled “Two Way Trade in Green Electrons,” written by three researchers at the Center for Energy and Environmental Policy Research at the Massachusetts’ Institute for Technology, Quebec’s hydropower, which like fossil fuels can be dispatched, will help cheaply and efficiently decarbonize these grids.

“Today transmission capacity is used to deliver energy south, from Quebec to the northeast,” the researchers wrote, adding, “…in a future low-carbon grid, it is economically optimal to use the transmission to send energy in both directions.”

That is, once new transmission lines and wind and solar power are built, New York and Massachusetts could send excess energy into Quebec where it could be stored in hydroelectric reservoirs until needed.

“This is the future of this northeast region, as New York state and New England are decarbonizing,” said Sutherland. “The only renewable energies they can put on the grid are intermittent, so they’re going to need this backup and right to the north of them, they’ve got Hydro-Québec as backup.”

Hydro-Québec already sells roughly 7 terrawatts of electricity per year into New York on the spot market, but Sutherland says it is constrained by transmission constraints that limit additional deliveries.

And because transmission lines can cost billions of dollars to build, he said Hydro-Québec needs the security of long-term contracts that ensure it will be paid back over time, aligning with its broader $185-billion transition strategy to reduce reliance on fossil fuels.

Sutherland expressed confidence that the Champlain Hudson Power Express project would be constructed by 2025. He noted its partners, Blackstone-backed Transmission Developers, have been working on the project for more than a decade, and have already won support from labour unions, some environmental groups and industry.

The project calls for a barge to move through Lake Champlain and the Hudson River, and dig a trench while unspooling and burying two high voltage cables, each about 10-12 centimetres in diameter. In certain sections of the Hudson River, known to have high concentrations of PCP pollutants, the cable would be buried underground alongside the river.

New England takes key step to 1.2 GW of Quebec hydro as Maine approves transmission line

NECEC Clean Energy Connect advances with Maine DEP permits, Hydro-Québec contracts, and rigorous transmission line mitigation, including tapered vegetation, culvert upgrades, and forest conservation, delivering low-carbon power, broadband fiber, and projected ratepayer savings.

 

Key Points

A Maine transmission project delivering Hydro-Québec power with strict DEP mitigation, lower bills, and added broadband.

✅ DEP permits mandate tapered vegetation, culvert upgrades, land conservation

✅ Hydro-Québec to supply 9.55 TWh/yr via MA contracts; bill savings 2-4%

✅ Added broadband fiber in Somerset and Franklin; local tax benefits

 

The Maine DEP reviewed the Clean Energy Connect project for more than two years, while regional interest in cross-border transmission continued to grow, before issuing permits that included additional environmental mitigation elements.

"Collectively, the requirements of the permit require an unprecedented level of environmental protection and compensatory land conservation for the construction of a transmission line in the state of Maine," DEP said in a May 11 statement.

Requirements include limits on transmission corridor width, forest preservation, culvert replacement and vegetation management projects, while broader grid programs like vehicle-to-grid integration enhance clean energy utilization across the region.

"In our original proposal we worked hard to develop a project that provided robust mitigation measures to protect the environment," NECEC Transmission CEO Thorn Dickinson said in a statement. "And through this permitting process, we now have made an exceedingly good project even better for Maine."

NECEC will be built on land owned or controlled by Central Maine Power. The 53 miles of new corridor on working forest land will use a new clearing technique for tapered vegetation, while the remainder of the project follows existing power lines.

Environmentalists said they agreed with the decision, and the mitigation measures state regulators took, noting similar momentum behind new wind investments in other parts of Canada.

"Building new ways to deliver low-carbon energy to our region is a critical piece of tackling the climate crisis," CLF Senior Attorney Phelps Turner said in a statement. "DEP was absolutely right to impose significant environmental conditions on this project and ensure that it does not harm critical wildlife areas."

Once complete, Turner said the transmission line will allow the region "to retire dirty fossil fuel plants in the coming years, which is a win for our health and our climate."

The Massachusetts Department of Public Utilities in June 2019 advanced the project by approving contracts for the state's utilities to purchase 9,554,940 MWh annually from Hydro-Quebec. Officials said the project is expected to provide approximately 2% to 4% savings on monthly energy bills.

Total net benefits to Massachusetts ratepayers over the 20-year contract, including both direct and indirect benefits, are expected to be approximately $4 billion, according to the state's estimates.

NECEC "will also deliver significant economic benefits to Maine and the region, including lower electricity prices, increased local real estate taxes and reduced energy costs with examples like battery-backed community microgrids demonstrating local resilience, expanded fiber optic cable for broadband service in Somerset and Franklin counties and funding of economic development for Western Maine," project developers said in a statement.​

Share of coal in UK's electricity system falls to record lows

UK Coal Phase-Out marks record-low coal generation as the UK grid shifts to renewable power, wind farms, and a net zero trajectory, slashing carbon emissions and supporting cleaner EV charging across the electricity system.

 

Key Points

UK Coal Phase-Out ends coal-fired electricity nationwide, powered by renewables and net zero policy to cut grid carbon.

✅ Coal's Q2 share fell to 0.7%, a record low

✅ Renewables up 12% with Beatrice wind farm

✅ EV charging grows cleaner as grid decarbonizes

 

The share of coal in the UK’s electricity system has fallen to record lows in recent months, alongside a coal-free power record, according to government data.

The figures show electricity generated by the UK’s most polluting power plants made up an average of 0.7% of the total in the second quarter of this year, a shift underway since wind first outpaced coal in 2016 across the UK. The amount of coal used to power the electricity grid fell by almost two-thirds compared with the same months last year.

A government spokesperson said coal-generated energy “will soon be a distant memory” as the UK moves towards becoming a net zero emissions economy, despite signs that low-carbon generation stalled in 2019 in some analyses.

“This new record low is a result of our world-leading low-carbon energy industry, which provided more than half of our energy last year and continues to go from strength to strength as we aim to end our contribution to climate change entirely by 2050,” the spokesperson said.

The UK electricity market is on track to end coal power after 142 years by the government’s target date of 2025.

This year three major energy companies have announced plans to close coal-fired power plants in the UK, which would leave only four remaining after the coming winter, ahead of the last coal power station going offline nationwide.

RWE said this month it would close the Aberthaw B power station in south Wales, its last UK coal plant, after the winter. SSE will close the Fiddler’s Ferry plant near Warrington, Cheshire, in March 2020, and EDF Energy will shutter the Cottam coal plant in September.

So far this year the UK has gone more than 3,000 hours without using coal for power, including a full week without coal earlier in the year – nearly five times more than the whole of 2017.

Meanwhile, the government’s data shows that renewable energy climbed by 12% from the second quarter of last year, boosted by the startup of the Beatrice windfarm in the Moray Firth in Scotland, and the UK leading the G20 in wind power share in recent assessments.

The cleaner power system could accelerate carbon savings from the UK’s roads, too, as more drivers opt for electric vehicles. A study by Imperial College London for the energy company Drax found that the UK’s increasingly low-carbon energy system meant electric cars were a greener option even when taking into account the carbon emissions produced by making car batteries.

Dr Iain Staffell, of Imperial College London, said: “An electric vehicle in the UK simply cannot be more polluting than its petrol or diesel equivalent – even when taking into account the upfront carbon cost of manufacturing their batteries. Any EV bought today could be emitting just a tenth of what a petrol car would in as little as five years’ time, as the electricity it uses to charge comes from an increasingly low-carbon mix.”

Bomb Cyclone Leaves Half a Million Without Power in Western Washington

Western Washington Bomb Cyclone unleashed gale-force winds, torrential rain, and coastal flooding, causing massive power outages from Seattle to Tacoma; storm surge, downed trees, and blocked roads hindered emergency response and infrastructure repairs.

 

Key Points

A rapidly deepening storm with severe winds, rain, flooding, and major power outages across Western Washington.

✅ Rapid barometric pressure drop intensified the system

✅ Gale-force winds downed trees and power lines

✅ Coastal flooding and storm surge disrupted transport

 

A powerful "bomb cyclone" recently hit Western Washington, causing widespread destruction across the region. The intense storm left more than half a million residents without power, similar to B.C. bomb cyclone outages seen to the north, with outages affecting communities from Seattle to Olympia. This weather phenomenon, marked by a rapid drop in atmospheric pressure, unleashed severe wind gusts, heavy rain, and flooding, causing significant disruption to daily life.

The bomb cyclone, which is a rapidly intensifying storm, typically features a sharp drop in barometric pressure over a short period of time. This creates extreme weather conditions, including gale-force winds, torrential rain, and coastal flooding, as seen during California storm impacts earlier in the season. In Western Washington, the storm struck just as the region was beginning to prepare for the winter season, catching many off guard with its strength and unpredictability.

The storm's impact was immediately felt as high winds downed trees, power lines, and other infrastructure. By the time the worst of the storm had passed, utility companies had reported widespread power outages, with more than 500,000 customers losing electricity. The outages were particularly severe in areas like Seattle, Tacoma, and the surrounding communities. Crews worked tirelessly in difficult conditions to restore power, but many residents faced extended outages, underscoring US grid climate vulnerabilities that complicate recovery efforts, with some lasting for days due to the scope of the damage.

The power outages were accompanied by heavy rainfall, leading to localized flooding. Roads were inundated, making it difficult for first responders and repair crews to reach affected areas. Emergency services were stretched thin as they dealt with downed trees, blocked roads, and flooded neighborhoods. In some areas, floodwaters reached homes, forcing people to evacuate. In addition, several schools were closed, and public transportation services were temporarily halted, leaving commuters stranded and businesses unable to operate.

As the storm moved inland, its effects continued to be felt. Western Washington’s coastal regions were hammered by high waves and storm surges, further exacerbating the damage. The combination of wind and rain also led to hazardous driving conditions, prompting authorities to advise people to stay off the roads unless absolutely necessary.

While power companies worked around the clock to restore electricity, informed by grid resilience strategies that could help utilities prepare for future events, challenges persisted. Fallen trees and debris blocked access to repair sites, and the sheer number of outages made it difficult for crews to restore power quickly. Some customers were left in the dark for days, forced to rely on generators, candles, and other makeshift solutions. The storm's intensity left a trail of destruction, requiring significant resources to address the damages and rebuild critical infrastructure.

In addition to the immediate impacts on power and transportation, the bomb cyclone raised important concerns about climate change and the increasing frequency of extreme weather events. Experts note that storms like these are becoming more common, with rapid intensification leading to more severe consequences and compounding pressures such as extreme-heat electricity costs for households. As the planet warms, scientists predict that such weather systems will continue to grow in strength, posing greater challenges to cities and regions that are not always prepared for such extreme events.

In the aftermath of the storm, local governments and utility companies faced the daunting task of not only restoring services but also assessing the broader impact of the storm on communities. Many areas, especially those hit hardest by flooding and power outages, will require substantial recovery efforts. The devastation of the bomb cyclone highlighted the vulnerability of infrastructure in the face of rapidly changing weather patterns and water availability, as seen in BC Hydro drought adaptations nearby, and reinforced the need for greater resilience in the face of future storms.

The storm's impact on the Pacific Northwest is a reminder of the power of nature and the importance of preparedness. As Western Washington recovers, there is a renewed focus on strengthening infrastructure, including expanded renewable electricity to diversify supply, improving emergency response systems, and ensuring that communities are better equipped to handle the challenges posed by increasingly severe weather events. For now, residents remain hopeful that the worst is behind them and are working together to rebuild and prepare for whatever future storms may bring.

The bomb cyclone has left an indelible mark on Western Washington, but it also serves as a call to action for better preparedness, more robust infrastructure, and a greater focus on combating climate change to mitigate the impact of such extreme weather in the future.

No deal Brexit could trigger electricity shock for Northern Ireland

Northern Ireland No-Deal Power Contingency outlines Whitehall plans to deploy thousands of generators on barges in the Irish Sea, safeguard the electricity market, and avert blackouts if Brexit disrupts imports from the Republic of Ireland.

 

Key Points

A UK Whitehall plan to prevent NI blackouts by deploying generators and protecting cross-border electricity flows.

✅ Barges in Irish Sea to host temporary power generators

✅ Mitigates loss of EU market access in a no-deal Brexit

✅ Ensures NI supply if Republic cuts electricity exports

 

Such a scenario could see thousands of electricity generators being requisitioned at short notice and positioned on barges in the Irish Sea, even as Great Britain's generation mix shapes wider supply dynamics, to help keep the region going, a Whitehall document quoted by the Financial Times states.

An emergency operation could see equipment being brought back from places like Afghanistan, where the UK still has a military presence, the newspaper said.

The extreme situation could arise because Northern Ireland shares a single energy market with the Irish Republic, where Irish grid price spikes have heightened concern about stability.

The region relies on energy imports from the Republic because it does not have enough generating capacity itself, and the UK is aiming to negotiate a deal to allow that single electricity market on the island of Ireland to continue post-EU withdrawal, while virtual power plant proposals for UK homes are explored to avoid outages, the FT stated.

However, if no Brexit deal is agreed Whitehall fears suppliers in the Irish Republic could cut off power because the UK would no longer be part of the European electricity market, and a recent short supply warning from National Grid underscores the risk.

In a bid to prevent blackouts in Northern Ireland in a worse case situation the Government would need to put thousands of generators into place, even as an emergency energy plan has reportedly not gone ahead nationwide, according to the report.

And officials fear they may need to commandeer some generators from the military in such a scenario, the FT reports.

An official was quoted by the newspaper as saying the preparations were “gob-smacking”.

A tenth of all electricity is lost in the grid - superconducting cables can help

High-Temperature Superconducting Cables enable lossless, high-voltage, underground transmission for grid modernization, linking renewable energy to cities with liquid nitrogen cooling, boosting efficiency, cutting emissions, reducing land use, and improving resilience against disasters and extreme weather.

 

Key Points

Liquid-nitrogen-cooled power cables delivering electricity with near-zero losses, lower voltage, and greater resilience.

✅ Near-lossless transmission links renewables to cities efficiently

✅ Operate at lower voltage, reducing substation size and cost

✅ Underground, compact, and resilient to extreme weather events

 

For most of us, transmitting power is an invisible part of modern life. You flick the switch and the light goes on.

But the way we transport electricity is vital. For us to quit fossil fuels, we will need a better grid, with macrogrid planning connecting renewable energy in the regions with cities.

Electricity grids are big, complex systems. Building new high-voltage transmission lines often spurs backlash from communities, as seen in Hydro-Que9bec power line opposition over aesthetics and land use, worried about the visual impact of the towers. And our 20th century grid loses around 10% of the power generated as heat.

One solution? Use superconducting cables for key sections of the grid. A single 17-centimeter cable can carry the entire output of several nuclear plants. Cities and regions around the world have done this to cut emissions, increase efficiency, protect key infrastructure against disasters and run powerlines underground. As Australia prepares to modernize its grid, it should follow suit with smarter electricity infrastructure initiatives seen elsewhere. It's a once-in-a-generation opportunity.


What's wrong with our tried-and-true technology?
Plenty.

The main advantage of high voltage transmission lines is they're relatively cheap.

But cheap to build comes with hidden costs later. A survey of 140 countries found the electricity currently wasted in transmission accounts for a staggering half-billion tons of carbon dioxide—each year.

These unnecessary emissions are higher than the exhaust from all the world's trucks, or from all the methane burned off at oil rigs.

Inefficient power transmission also means countries have to build extra power plants to compensate for losses on the grid.

Labor has pledged A$20 billion to make the grid ready for clean energy, and international moves such as US-Canada cross-border approvals show the scale of ambition needed. This includes an extra 10,000 kilometers of transmission lines. But what type of lines? At present, the plans are for the conventional high voltage overhead cables you see dotting the countryside.

System planning by Australia's energy market operator shows many grid-modernizing projects will use last century's technologies, the conventional high voltage overhead cables, even as Europe's HVDC expansion gathers pace across its network. If these plans proceed without considering superconductors, it will be a huge missed opportunity.


How could superconducting cables help?
Superconduction is where electrons can flow without resistance or loss. Built into power cables, it holds out the promise of lossless electricity transfer, over both long and short distances. That's important, given Australia's remarkable wind and solar resources are often located far from energy users in the cities.

High voltage superconducting cables would allow us to deliver power with minimal losses from heat or electrical resistance and with footprints at least 100 times smaller than a conventional copper cable for the same power output.

And they are far more resilient to disasters and extreme weather, as they are located underground.

Even more important, a typical superconducting cable can deliver the same or greater power at a much lower voltage than a conventional transmission cable. That means the space needed for transformers and grid connections falls from the size of a large gym to only a double garage.

Bringing these technologies into our power grid offers social, environmental, commercial and efficiency dividends.

Unfortunately, while superconductors are commonplace in Australia's medical community (where they are routinely used in MRI machines and diagnostic instruments) they have not yet found their home in our power sector.

One reason is that superconductors must be cooled to work. But rapid progress in cryogenics means you no longer have to lower their temperature almost to absolute zero (-273℃). Modern "high temperature" superconductors only need to be cooled to -200℃, which can be done with liquid nitrogen—a cheap, readily available substance.

Overseas, however, they are proving themselves daily. Perhaps the most well-known example to date is in Germany's city of Essen. In 2014, engineers installed a 10 kilovolt (kV) superconducting cable in the dense city center. Even though it was only one kilometer long, it avoided the higher cost of building a third substation in an area where there was very limited space for infrastructure. Essen's cable is unobtrusive in a meter-wide easement and only 70cm below ground.

Superconducting cables can be laid underground with a minimal footprint and cost-effectively. They need vastly less land.

A conventional high voltage overhead cable requires an easement of about 130 meters wide, with pylons up to 80 meters high to allow for safety. By contrast, an underground superconducting cable would take up an easement of six meters wide, and up to 2 meters deep.

This has another benefit: overcoming community skepticism. At present, many locals are concerned about the vulnerability of high voltage overhead cables in bushfire-prone and environmentally sensitive regions, as well as the visual impact of the large towers and lines. Communities and farmers in some regions are vocally against plans for new 85-meter high towers and power lines running through or near their land.

Climate extremes, unprecedented windstorms, excessive rainfall and lightning strikes can disrupt power supply networks, as the Victorian town of Moorabool discovered in 2021.

What about cost? This is hard to pin down, as it depends on the scale, nature and complexity of the task. But consider this—the Essen cable cost around $20m in 2014. Replacing the six 500kV towers destroyed by windstorms near Moorabool in January 2020 cost $26 million.

While superconducting cables will cost more up front, you save by avoiding large easements, requiring fewer substations (as the power is at a lower voltage), and streamlining approvals.


Where would superconductors have most effect?
Queensland. The sunshine state is planning four new high-voltage transmission projects, to be built by the mid-2030s. The goal is to link clean energy production in the north of the state with the population centers of the south, similar to sending Canadian hydropower to New York to meet demand.

Right now, there are major congestion issues between southern and central Queensland, and subsea links like Scotland-England renewable corridors highlight how to move power at scale. Strategically locating superconducting cables here would be the best location, serving to future-proof infrastructure, reduce emissions and avoid power loss.
