Downed power line kills three

Yukon Electricity Demand Record underscores peak load growth as winter cold snaps drive heating, lighting, and EV charging, blending hydro, LNG, and diesel with renewable energy and planned grid-scale battery storage in Whitehorse.

Key Points

It is the territory's new peak electricity load, reflecting winter demand, electric heating, EVs, and mixed generation.

✅ New peak: 104.42 MW, surpassing 2020 record of 103.84 MW

✅ Winter peaks met with hydro, LNG, diesel, and renewables mix

✅ Customers urged to shift use off peak hours and use timers

A new record for electricity demand has been set in Yukon. The territory recorded a peak of 104.42 megawatts, according to a news release from Yukon Energy.

The new record is about a half a megawatt higher than the previous record of 103.84 megawatts recorded on Jan. 14, 2020.

While in general, over 90 per cent of the electricity generated in Yukon comes from renewable resources each year, with initiatives such as new wind turbines expanding capacity, during periods of high electricity use each winter, Yukon Energy has to use its hydro, liquefied natural gas and diesel resources to generate the electricity, the release says.

But when it comes to setting records, Andrew Hall, CEO of Yukon Energy, says it's not that unusual.

"Typically, during the winter, when the weather is cold, demand for electricity in the Yukon reaches its maximum. And that's because folks use more electricity for heating their homes, for cooking meals, there's more lighting demand, because the days are shorter," he said.

"It usually happens either in December or sometimes in January, when we get a cold snap."

He said generally over the years, electricity demand has grown.

"We get new home construction, construction of new apartment buildings. And typically, those new homes are all heated by electricity, maybe not all of them but the majority," Hall said.

Efforts to curb climate change add to electricity demand
There are also other reasons, ones that are "in the name of climate change," Hall added.

That includes people trying to limit fossil fuel heating by swapping to electric heating. And, he said some Yukoners are switching to electric vehicles as incentives expand across the North.

"Over time, those two new demands, in the name of climate change, will also contribute to growing demand for electricity," he said.

While Yukon did reach this new all time high, Hall said the territory still hadn't hit the maximum capacity for the week, which was 118 megawatts, and discussions about a potential connection to the B.C. grid are part of long-term planning.

Tips to curve demand
"When we plan our system, we actually plan for a scenario, guided by the view that sustainability is key to the grid's future, where we actually lose our largest hydro generating facility," Hall said.

"We had plenty of generation available so it wasn't an emergency situation, and, even as other provinces face electricity shortages, it was more just an observation that hey, our peaks are growing."

He also said it was an opportunity to reach out to customers on ways to curve their demand for electricity around peak times, drawing on energy efficiency insights from other provinces, which is typically between 7 a.m. and 9 a.m., and between 5 p.m. and 7 p.m., Monday to Friday.

For example, he said, people should consider running major appliances, like dishwashers, during non-peak hours, such as in the afternoon rather than in the morning or evening.

During winter peaks, people can also use a block heater timer on vehicles and turn down the thermostat by one or two degrees.

'We plan for each winter'
Hall said Yukon Energy is working to increase its peak output, including working on a large grid scale battery to be installed in Whitehorse, similar to Ontario's energy storage push now underway. 

When it comes to any added load from people working from home due to COVID-19, Hall said they haven't noticed any identifiable increase there.

"Presumably, if someone's working from home, you know, their computer is at home, and they're not using the computer at the office," he said.

Yukon Energy one step closer to having largest battery storage site in the North
He said there shouldn't be any concern for maxing out the capacity of electricity demand as Yukon moves into the colder winter months, since those days are forecast for.

"This number of 104 megawatts wasn't unexpected," he said, adding how much electricity is needed depends on the weather too.

"We plan for each winter."

Eviation Collapse underscores electric aviation headwinds, from Alice aircraft battery limits to FAA/EASA certification hurdles, funding shortfalls, and leadership instability, reshaping sustainability roadmaps for regional airliners and future zero-emission flight.

Key Points

Eviation Collapse is the 2025 shutdown of Eviation Aircraft, revealing battery, certification, and funding hurdles.

✅ Battery energy density limits curtailed Alice's range

✅ FAA/EASA certification timelines delayed commercialization

✅ Funding gaps and leadership churn undermined execution

The electric aviation industry was poised to revolutionize the skies through an aviation revolution with startups like Eviation Aircraft leading the charge to bring environmentally friendly, cost-efficient electric airplanes into commercial use. However, in a shocking turn of events, Eviation has faced an abrupt collapse, signaling challenges that may impact the future of electric flight.

Eviation’s Vision and Early Promise

Founded in 2015, Eviation was an ambitious electric airplane startup with the goal of changing the way the world thinks about aviation. The company’s flagship product, the Alice aircraft, was designed to be an all-electric regional airliner capable of carrying up to 9 passengers. With a focus on sustainability, reduced operating costs, and a quieter flight experience, Alice attracted attention as one of the most promising electric aircraft in development.

Eviation’s aircraft was aimed at replacing small, inefficient, and environmentally damaging regional aircraft, reducing emissions in the aviation industry. The startup’s vision was bold: to create an airplane that could offer all the benefits of electric power – lower operating costs, less noise, and a smaller environmental footprint. Their goal was not only to attract major airlines but also to pave the way for a more sustainable future in aviation.

The company’s early success was driven by substantial investments and partnerships. It garnered attention from aviation giants and venture capitalists alike, drawing support for its innovative technology. In fact, in 2019, Eviation secured a deal with the Israeli airline, El Al, for several aircraft, a deal that seemed to promise a bright future for the company.

Challenges in the Electric Aviation Industry

Despite its early successes and strong backing, Eviation faced considerable challenges that eventually contributed to its downfall. The electric aviation sector, as promising as it seemed, has always been riddled with hurdles – from battery technology to regulatory approvals, and compounded by Europe’s EV slump that dampened clean-transport sentiment, the path to producing commercially viable electric airplanes has proven more difficult than initially anticipated.

The first major issue Eviation encountered was the slow development of battery technology. While electric car companies like Tesla were able to scale their operations quickly during the electric vehicle boom due to advancements in battery efficiency, aviation technology faced a more significant obstacle. The energy density required for a plane to fly long distances with sufficient payload was far greater than what existing battery technology could offer. This limitation severely impacted the range of the Alice aircraft, preventing it from meeting the expectations set by its creators.

Another challenge was the lengthy regulatory approval process for electric aircraft. Aviation is one of the most regulated industries in the world, and getting a new aircraft certified for flight takes time and rigorous testing. Although Eviation’s Alice was touted as an innovative leap in aviation technology, the company struggled to navigate the complex process of meeting the safety and operational standards required by aviation authorities, such as the FAA and EASA.

Financial Difficulties and Leadership Changes

As challenges mounted, Eviation’s financial situation became increasingly precarious. The company struggled to secure additional funding to continue its development and scale operations. Investors, once eager to back the promising startup, grew wary as timelines stretched and costs climbed, amid a U.S. EV market share dip in early 2024, tempering enthusiasm. With the electric aviation market still in its early stages, Eviation faced stiff competition from more established players, including large aircraft manufacturers like Boeing and Airbus, who also began to invest heavily in electric and hybrid-electric aircraft technologies.

Leadership instability also played a role in Eviation’s collapse. The company went through several executive changes over a short period, and management’s inability to solidify a clear vision for the future raised concerns among stakeholders. The lack of consistent leadership hindered the company’s ability to make decisions quickly and efficiently, further exacerbating its financial challenges.

The Sudden Collapse

In 2025, Eviation made the difficult decision to shut down its operations. The company announced the closure after failing to secure enough funding to continue its development and meet its ambitious production goals. The sudden collapse of Eviation sent shockwaves through the electric aviation sector, where many had placed their hopes on the startup’s innovative approach to electric flight.

The failure of Eviation has left many questioning the future of electric aviation. While the industry is still in its infancy, Eviation’s downfall serves as a cautionary tale about the challenges of bringing cutting-edge technology to the skies. The ambitious vision of a sustainable, electric future in aviation may still be achievable, but the path to success will require overcoming significant technological, regulatory, and financial obstacles.

What’s Next for Electric Aviation?

Despite Eviation’s collapse, the electric aviation sector is far from dead. Other companies, such as Joby Aviation, Vertical Aerospace, and Ampaire, are continuing to develop electric and hybrid-electric aircraft, building on milestones like Canada’s first commercial electric flight that signal ongoing demand for green alternatives to traditional aviation.

Moreover, major aircraft manufacturers are doubling down on their own electric aircraft projects. Boeing, for example, has launched several initiatives aimed at reducing carbon emissions in aviation, while Harbour Air’s point-to-point e-seaplane flight showcases near-term regional progress, and Airbus is testing a hybrid-electric airliner prototype. The collapse of Eviation may slow down progress, but it is unlikely to derail the broader movement toward electric flight entirely.

The lessons learned from Eviation’s failure will undoubtedly inform the future of the electric aviation sector. Innovation, perseverance, and a steady stream of investment will be critical for the success of future electric aircraft startups, as exemplified by Harbour Air’s research-driven electric aircraft efforts that highlight the value of sustained R&D. While the dream of electric planes may have suffered a setback, the long-term vision of cleaner, more sustainable aviation is still alive.

Canada Clean Electricity drives a net-zero grid by 2035, scaling renewables like wind, solar, and hydro, with storage, smart grids, interprovincial transmission, and electrification of vehicles, buildings, and industry to cut emissions and costs.

Key Points

Canada Clean Electricity is a shift to a net-zero grid by 2035 using renewables, storage, and smart grids to decarbonize

✅ Doubles non-emitting generation for electrified transport and heating

✅ Expands wind, solar, hydro with storage and smart-grid balancing

✅ Builds interprovincial lines and faster permitting with Indigenous partners

By Merran Smith and Mark Zacharias

Canada is an electricity heavyweight. In addition to being the world’s sixth-largest electricity producer and third-largest electricity exporter in the global electricity market today, Canada can boast an electricity grid that is now 83 per cent emission-free, not to mention residential electricity rates that are the cheapest in the Group of Seven countries.

Indeed, on the face of it, the country’s clean electricity system appears poised for success. With an abundance of sunshine and blustery plains, Alberta and Saskatchewan, the Prairie provinces most often cited for wind and solar, have wind- and solar-power potential that rivals the best on the continent. Meanwhile, British Columbia, Manitoba, Quebec, and Newfoundland and Labrador have long excelled at generating low-cost hydro power.

So it would only be natural to assume that Canada, with this solid head start and its generous geography, is already positioned to provide enough affordable clean electricity to power our much-touted net-zero and economic ambitions.

But the reality is that Canada, like most countries, is not yet prepared for a world increasingly committed to carbon neutrality, in part because demand for solar electricity has lagged, even as overall momentum grows.

The federal government’s forthcoming Clean Electricity Standard – a policy promised by the governing Liberals during the most recent election campaign and restated for an international audience by Prime Minister Justin Trudeau at the United Nations’ COP26 climate summit – would require all electricity in the country to be net zero by 2035 nationwide, setting a new benchmark. But while that’s an encouraging start, it is by no means the end goal. Electrification – that is, hooking up our vehicles, heating systems and industry to a clean electricity grid – will require Canada to produce roughly twice as much non-emitting electricity as it does today in just under three decades.

This massive ramp-up in clean electricity will require significant investment from governments and utilities, along with their co-operation on measures and projects such as interprovincial power lines to build an electric, connected and clean system that can deliver benefits nationwide. It will require energy storage solutions, smart grids to balance supply and demand, and energy-efficient buildings and appliances to cut energy waste.

While Canada has mostly relied on large-scale hydroelectric and nuclear power in the past, newer sources of electricity such as solar, wind, geothermal, and biomass with carbon capture and storage will, in many cases, be the superior option going forward, thanks to the rapidly falling costs of such technology and shorter construction times. And yet Canada added less solar and wind generation in the past five years than all but three G20 countries – Indonesia, Russia and Saudi Arabia, with some experts calling it a solar power laggard in recent years. That will need to change, quickly.

In addition, Canada’s Constitution places electricity policy under provincial jurisdiction, which has produced a patchwork of electricity systems across the country that use different energy sources, regulatory models, and approaches to trade and collaboration. While this model has worked to date, given our low consumer rates and high power reliability, collaborative action and a cohesive vision will be needed – not just for a 100-per-cent clean grid by 2035, but for a net-zero-enabling one by 2050.

Right now, it takes too long to move a clean power project from the proposal stage to operation – and far too long if we hope to attain a clean grid by 2035 and a net-zero-enabling one by 2050. This means that federal, provincial, territorial and Indigenous governments must work with rural communities and industry stakeholders to accelerate the approvals, financing and construction of clean energy projects and provide investor certainty.

In doing so, Canada can set a course to carbon neutrality while driving job creation and economic competitiveness, a transition many analyses deem practical and profitable in the long run. Our closest trading partners and many of the world’s largest companies and investors are demanding cleaner goods. A clean grid underpins clean production, just as it underpins our climate goals.

The International Energy Agency estimates that, for the world to reach net zero by 2050, clean electricity generation worldwide must increase by more than 2.5 times between today and 2050. Countries are already plotting their energy pathways, and there is much to learn from each other.

Consider South Australia. The state currently gets 62 per cent of its electricity from wind and solar and, combined with grid-scale battery storage, has not lost a single hour of electricity in the past five years. South Australia expects 100 per cent of its electricity to come from renewable sources before 2030. An added bonus given today’s high energy prices: Annual household electricity costs have declined there by 303 Australian dollars ($276) since 2018.

The transition to clean energy is not about sacrificing our way of life – it’s about improving it. But we’ll need the power to make it happen. That work needs to start now.

UK 2-GW Substation strengthens National Grid power transmission in Kent, enabling offshore wind integration, voltage regulation, and grid modernization to meet rising electricity demand and support the UK energy transition with resilient, reliable infrastructure.

Key Points

National Grid facility in Kent that steps voltage, regulates power, and connects offshore wind to strengthen UK grid.

✅ Adds 2 GW capacity to meet rising electricity demand

✅ Integrates offshore wind farms into transmission network

✅ Improves reliability, voltage control, and grid resilience

The United Kingdom has strengthened its national power grid with the commissioning of a major new 2-gigawatt capacity substation in Kent. This massive project, a key part of the National Grid's ongoing efforts to modernize and expand power transmission infrastructure, including plans to fast-track grid connections across critical projects, will play a critical role in supporting the UK's energy transition and growing electricity demands.

What is a Substation?

Substations are vital components of electricity grids. They serve as connection points, transforming high voltage electricity from power plants to lower voltages suitable for homes and businesses. They also help to regulate voltage levels, and, where appropriate, interface with expanding HVDC technology initiatives, ensuring stable electricity delivery.  Modern substations often act as hubs, supporting the integration of renewable power sources with the main electricity network.

Why This Substation Is Important

The new 2-gigawatt capacity substation is significant for several reasons:

• Expanding Capacity: It adds significant capacity to the UK's grid, enabling the transmission of large amounts of electricity to where it's needed. This capacity boost is crucial for supporting growing electricity demand as the UK shifts its energy mix towards renewable sources.
• Integrating Renewables: The substation will aid in integrating substantial amounts of offshore wind power, as projects like the Scotland-England subsea link illustrate, helping the UK achieve its ambitious clean energy goals. Offshore wind farms are a booming source of renewable energy in the UK, and ensuring reliable connections to the grid is essential in maximizing their potential.
• Future-Proofing the Grid: The newly commissioned substation helps bolster the reliability and resilience of the UK's power transmission network, where reducing losses with superconducting cables could further enhance efficiency. It will play a key role in securing electricity supplies as older power plants are decommissioned and renewable energy sources become more dominant.

A Landmark Project

The commissioning of this substation is a major achievement for the National Grid, amid an independent operator transition underway in the sector, and UK energy infrastructure upgrades. The sheer scale of the project required extensive planning and collaboration with various stakeholders, underscoring the complexity of upgrading the nation's power grid to meet future needs.

The Path Towards a Cleaner Grid

The new substation is not an isolated project. It is part of a broader, multi-year effort by the National Grid to modernize and expand the country's power grid.  This entails building new transmission lines and urban conduits such as London's newest electricity tunnel now in service, investing in storage technologies, and adapting infrastructure to accommodate the shift towards distributed energy generation, where power is generated closer to the point of use.

Beyond Substations

While projects like the new 2-gigawatt substation are crucial, ensuring a successful energy transition requires more than just infrastructure upgrades. Continued support for renewable energy development, highlighted by recent offshore wind power milestones that demonstrate grid-readiness, investment in emerging energy storage solutions, and smart grid technology that leverages data for effective grid management are all important components of building a cleaner and more resilient energy future for the UK.

Muskrat Falls Financing Restructuring redirects megadam benefits to ratepayers, stabilizes electricity rates, and overhauls federal provincial loan guarantees for the hydro project, addressing cost overruns flagged by the Public Utilities Board in Newfoundland and Labrador.

Key Points

A revised funding model shifting benefits to ratepayers to curb rate hikes linked to Muskrat Falls cost overruns.

✅ Shields ratepayers from megadam cost overruns

✅ Revises federal provincial loan guarantees

✅ Targets stable electricity rates by 2021 and beyond

Ottawa and Newfoundland and Labrador say they will rewrite the financial structure of the Muskrat Falls hydro project to shield ratepayers from paying for the megadam's cost overruns.

Federal Natural Resources Minister Seamus O'Regan and Premier Dwight Ball announced Monday that their two governments would scrap the financial structure agreed upon in past federal-provincial loan agreements, moving to a model that redirects benefits, such as a lump sum credit, to ratepayers.

Both politicians called the announcement, which was light on dollar figures, a major milestone in easing residents' fears that electricity rates will spike sharply, as seen with Nova Scotia's debated 14% hike, when the over-budget dam comes fully online next year.
"We are in a far better place today thanks to this comprehensive plan," Ball said.

Ball has said the issue of electricity rates is a top priority for his government, and he has pledged to keep rates near existing levels, but rate mitigation talks with Ottawa have dragged on since April.

A report by the province's Public Utilities Board released Friday forecast an "unprecedented" 75 per cent increase in average domestic rates for island residents in 2021, while Nova Scotia's regulator approved a 14% hike, and reported concerns from industrial customers about their ability to remain competitive.

Costs of the Muskrat Falls megadam on Labrador's Lower Churchill River have ballooned to more than $12.7 billion since the project was approved in 2012, according to the latest estimate of Crown corporation Nalcor Energy.

The dam is set to produce more power than the province can sell. Its existing financial structure would have left electricity ratepayers paying for Muskrat Falls to make up the difference starting in 2021, an issue both governments said Monday has been resolved with the relaunch of financing talks.

"Essentially, you won't pay this on your monthly light bills," Ball said.

But details of how the project will meet financing requirements in coming decades to make up the gap in funds are still to be worked out.

Both Ball and O'Regan criticized previous governments for sanctioning the poorly planned development and again pledged their commitment to easing the burden on residents.

"We promised we would be there to help, and we will be," O'Regan said before announcing a "relaunch" of negotiations around the project's financial structure.

He did not say how much the new setup might cost the federal government, despite earlier federal funding commitments, stressing that the new focus will be on the project's long-term sustainability. "There's no single piece of policy ... that can resolve such a large and complicated mess," O'Regan said.

The two governments also said they will work towards electrifying federal buildings to reduce an anticipated power surplus in the province.

In the short term, the federal government said it would allow for "flexibility" in upcoming cash requirements related to debt servicing, allowing deferral of payments if necessary.

Ball said that flexibility was built in to ensure the plan would still be applicable if costs continue to rise before Muskrat Falls is commissioned.

Political opponents criticized Monday's plan as lacking detail.

"What I heard talked about was an agreement that in the future, there's going to be an agreement," said Progressive Conservative Leader Ches Crosbie. "This was an occasion to reassure people that there's a plan in place to make life here affordable, and I didn't see that happen today."

Others addressed the lingering questions about the project's final cost.

Nalcor's latest financial update has remained unchanged since 2017, though the Muskrat Falls project has seen additional delays related to staffing and software issues.

Dennis Browne, the province's consumer advocate, said the switch to a cost of service model is a significant move that will benefit ratepayers, but he said it's impossible to truly restructure the project while it's a work in progress. "We need to know what the figures are, and we don't have them," he said.

Offshore wind power accelerates low-carbon electrification, leveraging floating turbines, high capacity factors, HVDC transmission, and hydrogen production to decarbonize grids, cut CO2, and deliver competitive, reliable renewable energy near demand centers.

Key Points

Offshore wind power uses offshore turbines to deliver low-carbon electricity with high capacity factors and falling costs.

✅ Sea-based wind farms with 40-50% capacity factors

✅ Floating turbines unlock deep-water, far-shore resources

✅ Enables hydrogen production and strengthens grid reliability

The need for affordable low-carbon technologies is greater than ever

Global energy-related CO2 emissions reached a historic high in 2018, driven by an increase in coal use in the power sector. Despite impressive gains for renewables, fossil fuels still account for nearly two-thirds of electricity generation, the same share as 20 years ago. There are signs of a shift, with increasing pledges to decarbonise economies and tackle air pollution, and with World Bank support helping developing countries scale wind, but action needs to accelerate to meet sustainable energy goals. As electrification of the global energy system continues, the need for clean and affordable low-carbon technologies to produce this electricity is more pressing than ever. This World Energy Outlook special report offers a deep dive on a technology that today has a total capacity of 23 GW (80% of it in Europe) and accounts for only 0.3% of global electricity generation, but has the potential to become a mainstay of the world's power supply. The report provides the most comprehensive analysis to date of the global outlook for offshore wind, its contributions to electricity systems and its role in clean energy transitions.

The offshore wind market has been gaining momentum

The global offshore wind market grew nearly 30% per year between 2010 and 2018, benefitting from rapid technology improvements. Over the next five years, about 150 new offshore wind projects are scheduled to be completed around the world, pointing to an increasing role for offshore wind in power supplies. Europe has fostered the technology's development, led by the UK offshore wind sector alongside Germany and Denmark. The United Kingdom and Germany currently have the largest offshore wind capacity in operation, while Denmark produced 15% of its electricity from offshore wind in 2018. China added more capacity than any other country in 2018.

The untapped potential of offshore wind is vast

The best offshore wind sites could supply more than the total amount of electricity consumed worldwide today. And that would involve tapping only the sites close to shores. The IEA initiated a new geospatial analysis for this report to assess offshore wind technical potential country by country. The analysis was based on the latest global weather data on wind speed and quality while factoring in the newest turbine designs. Offshore wind's technical potential is 36 000 TWh per year for installations in water less than 60 metres deep and within 60 km from shore. Global electricity demand is currently 23 000 TWh. Moving further from shore and into deeper waters, floating turbines could unlock enough potential to meet the world's total electricity demand 11 times over in 2040. Our new geospatial analysis indicates that offshore wind alone could meet several times electricity demand in a number of countries, including in Europe, the United States and Japan. The industry is adapting various floating foundation technologies that have already been proven in the oil and gas sector. The first projects are under development and look to prove the feasibility and cost-effectiveness of floating offshore wind technologies.

Offshore wind's attributes are very promising for power systems

New offshore wind projects have capacity factors of 40-50%, as larger turbines and other technology improvements are helping to make the most of available wind resources. At these levels, offshore wind matches the capacity factors of gas- and coal-fired power plants in some regions – though offshore wind is not available at all times. Its capacity factors exceed those of onshore wind and are about double those of solar PV. Offshore wind output varies according to the strength of the wind, but its hourly variability is lower than that of solar PV. Offshore wind typically fluctuates within a narrower band, up to 20% from hour to hour, than solar PV, which varies up to 40%.

Offshore wind's high capacity factors and lower variability make its system value comparable to baseload technologies, placing it in a category of its own – a variable baseload technology. Offshore wind can generate electricity during all hours of the day and tends to produce more electricity in winter months in Europe, the United States and China, as well as during the monsoon season in India. These characteristics mean that offshore wind's system value is generally higher than that of its onshore counterpart and more stable over time than that of solar PV. Offshore wind also contributes to electricity security, with its high availability and seasonality patterns it is able to make a stronger contribution to system needs than other variable renewables. In doing so, offshore wind contributes to reducing CO2 and air pollutant emissions while also lowering the need for investment in dispatchable power plants. Offshore wind also has the advantage of avoiding many land use and social acceptance issues that other variable renewables are facing.

Offshore wind is on track to be a competitive source of electricity

Offshore wind is set to be competitive with fossil fuels within the next decade, as well as with other renewables including solar PV. The cost of offshore wind is declining and is set to fall further. Financing costs account for 35% to 50% of overall generation cost, and supportive policy frameworks are now enabling projects to secure low cost financing in Europe, with zero-subsidy tenders being awarded. Technology costs are also falling. The levelised cost of electricity produced by offshore wind is projected to decline by nearly 60% by 2040. Combined with its relatively high value to the system, this will make offshore wind one of the most competitive sources of electricity. In Europe, recent auctions indicate that offshore wind will soon beat new natural gas-fired capacity on cost and be on a par with solar PV and onshore wind. In China, offshore wind is set to become competitive with new coal-fired capacity around 2030 and be on par with solar PV and onshore wind. In the United States, recent project proposals indicate that offshore wind will soon be an affordable option, even as the 1 GW timeline continues to evolve, with potential to serve demand centres along the country's east coast.

Innovation is delivering deep cost reductions in offshore wind, and transmission costs will become increasingly important. The average upfront cost to build a 1 gigawatt offshore wind project, including transmission, was over $4 billion in 2018, but the cost is set to drop by more than 40% over the next decade. This overall decline is driven by a 60% reduction in the costs of turbines, foundations and their installation. Transmission accounts for around one-quarter of total offshore wind costs today, but its share in total costs is set to increase to about one-half as new projects move further from shore. Innovation in transmission, for example through work to expand the limits of direct current technologies, will be essential to support new projects without raising their overall costs.

Offshore wind is set to become a $1 trillion business

Offshore wind power capacity is set to increase by at least 15-fold worldwide by 2040, becoming a $1 trillion business. Under current investment plans and policies, the global offshore wind market is set to expand by 13% per year, reflecting its growth despite Covid-19 in recent years, passing 20 GW of additions per year by 2030. This will require capital spending of $840 billion over the next two decades, almost matching that for natural gas-fired or coal-fired capacity. Achieving global climate and sustainability goals would require faster growth: capacity additions would need to approach 40 GW per year in the 2030s, pushing cumulative investment to over $1.2 trillion. 

The promising outlook for offshore wind is underpinned by policy support in an increasing number of regions. Several European North Seas countries – including the United Kingdom, Germany, the Netherlands and Denmark – have policy targets supporting offshore wind. Although a relative newcomer to the technology, China is quickly building up its offshore wind industry, aiming to develop a project pipeline of 10 GW by 2020. In the United States, state-level targets and federal incentives are set to kick-start the U.S. offshore wind surge in the coming years. Additionally, policy targets are in place and projects under development in Korea, Japan, Chinese Taipei and Viet Nam.

 The synergies between offshore wind and offshore oil and gas activities provide new market opportunities. Since offshore energy operations share technologies and elements of their supply chains, oil and gas companies started investing in offshore wind projects many years ago. We estimate that about 40% of the full lifetime costs of an offshore wind project, including construction and maintenance, have significant synergies with the offshore oil and gas sector. That translates into a market opportunity of $400 billion or more in Europe and China over the next two decades. The construction of foundations and subsea structures offers potential crossover business, as do practices related to the maintenance and inspection of platforms. In addition to these opportunities, offshore oil and gas platforms require electricity that is often supplied by gas turbines or diesel engines, but that could be provided by nearby wind farms, thereby reducing CO2 emissions, air pollutants and costs.

Offshore wind can accelerate clean energy transitions

Offshore wind can help drive energy transitions by decarbonising electricity and by producing low-carbon fuels. Over the next two decades, its expansion could avoid between 5 billion and 7 billion tonnes of CO2 emissions from the power sector globally, while also reducing air pollution and enhancing energy security by reducing reliance on imported fuels. The European Union is poised to continue leading the wind energy at sea in Europe industry in support of its climate goals: its offshore wind capacity is set to increase by at least fourfold by 2030. This growth puts offshore wind on track to become the European Union's largest source of electricity in the 2040s. Beyond electricity, offshore wind's high capacity factors and falling costs makes it a good match to produce low-carbon hydrogen, a versatile product that could help decarbonise the buildings sector and some of the hardest to abate activities in industry and transport. For example, a 1 gigawatt offshore wind project could produce enough low-carbon hydrogen to heat about 250 000 homes. Rising demand for low-carbon hydrogen could also dramatically increase the market potential for offshore wind. Europe is looking to develop offshore "hubs" for producing electricity and clean hydrogen from offshore wind.

It's not all smooth sailing

Offshore wind faces several challenges that could slow its growth in established and emerging markets, but policy makers and regulators can clear the path ahead. Developing efficient supply chains is crucial for the offshore wind industry to deliver low-cost projects. Doing so is likely to call for multibillion-dollar investments in ever-larger support vessels and construction equipment. Such investment is especially difficult in the face of uncertainty. Governments can facilitate investment of this kind by establishing a long-term vision for offshore wind and by drawing on U.K. policy lessons to define the measures to be taken to help make that vision a reality. Long-term clarity would also enable effective system integration of offshore wind, including system planning to ensure reliability during periods of low wind availability.

The success of offshore wind depends on developing onshore grid infrastructure. Whether the responsibility for developing offshore transmission lies with project developers or transmission system operators, regulations should encourage efficient planning and design practices that support the long-term vision for offshore wind. Those regulations should recognise that the development of onshore grid infrastructure is essential to the efficient integration of power production from offshore wind. Without appropriate grid reinforcements and expansion, there is a risk of large amounts of offshore wind power going unused, and opportunities for further expansion could be stifled. Development could also be slowed by marine planning practices, regulations for awarding development rights and public acceptance issues.

The future of offshore wind looks bright but hinges on the right policies

The outlook for offshore wind is very positive as efforts to decarbonise and reduce local pollution accelerate. While offshore wind provides just 0.3% of global electricity supply today, it has vast potential around the world and an important role to play in the broader energy system. Offshore wind can drive down CO2 emissions and air pollutants from electricity generation. It can also do so in other sectors through the production of clean hydrogen and related fuels. The high system value of offshore wind offers advantages that make a strong case for its role alongside other renewables and low-carbon technologies. Government policies will continue to play a critical role in the future of offshore wind and  the overall pace of clean energy transitions around the world.
