Our nationÂ’s coal-fired power plants are increasingly being retrofitted with technologies to mitigate the output of various forms of pollution, but a number of bad apples do continue to cause more than their fair share of mercury emissions.

This past March the Environmental Defense Fund, a leading nonprofit, released a report showing that the top 25 emitters of mercury, a potent neurotoxin and a nasty by-product of coal-fired electricity generation, contribute only 8 percent of the U.S. electric supply. At the same time, these power plants, which have failed to install readily available pollution controls already widely in use by other plants, account for nearly a third of all mercury emissions by the American electricity sector overall.

The report, “Mercury Alert: Cleaning up Coal Plants for Healthier Lives,” factors in emissions of mercury at power plants across the country in 2009. According to EDF, 20 of the top 25 mercury emitters are located within 50-100 miles of some of the largest metropolitan areas in the nation, including Chicago, Dallas, Houston, Atlanta, Minneapolis, Detroit, Pittsburgh, Cleveland, St. Louis and Austin. EDF found that Texas produces the most pollution from coal-fired electricity generation of all the U.S. states.

Besides listing the worst mercury polluters, the report also details recent cases of mercury contamination and fish consumption advisories across the country, as well as reported new installations of mercury controls and recently enacted state regulations driving their implementation.

The release of the report was timed to coincide with the announcement by the U.S. Environmental Protection Agency of more stringent rules regarding emissions of mercury and other air pollutants such as arsenic, dioxin and acid gases from individual power plants. EDF hopes that the report will bolster public support for the federal government to crack down on any plants that continue to buck the trend toward cleaner operations.

“There are widely available, cost-effective and tested technologies to reduce mercury pollution from power plants by more than 90 percent,” reports EDF. Currently only 17 U.S. states regulate mercury air emissions, but the upcoming EPA rule will force plants even in unregulated states to clean up their acts.

Mercury pollution is an ongoing problem around the world. Exposure to mercury in the environment has been linked to a variety of reproductive, cardiovascular and other human health problems. Airborne mercury from electricity plants usually finds its way into waterways and eventually the ocean, where it is taken up by successively larger marine life as it works its way up the food chain. The top ocean predators such as tuna and swordfish contain relatively large amounts of mercury in their fatty tissue as a result of eating smaller fish which have in turn eaten even smaller forms of marine life.

Consumers can limit their mercury intake by minimizing consumption of these larger fish including albacore canned tuna, but the problem will linger long into the future even if we start to reign in mercury pollution domestically, especially because the cleaner technologies being implemented here may take decades to find their way to power plants in poor and developing countries.

Want Clean And Universal Electricity? Create The Incentives To Double The Investment, World Leaders Say

IRENA Climate Investment Platform accelerates renewable energy financing through de-risking, bankable projects, and public-private partnerships, advancing Paris Agreement goals via grid integration, microgrids, and decarbonization while expanding access, jobs, and sustainable economic growth.

 

Key Points

A global platform linking bankable renewable projects with finance, derisking and partners to scale decarbonization.

✅ Connects developers with banks, funds, and insurers

✅ Promotes de-risking via policy, PPAs, and legal frameworks

✅ Targets Paris goals with grid, microgrids, and off-grid access

 

The heads-of-state and energy ministers from more than 120 nations just met in Abu Dhabi and they had one thing in common: a passion to increase the use of renewable energy to reduce the threat from global warming — one that will also boost economic output and spread prosperity. Access to finance, though, is critical to this goal. 

Indeed, the central message to emerge from the conference hosted by the International Renewable Energy Agency (IRENA) this week in the United Arab Emirates is that a global energy transition is underway that has the potential to revitalize economies and to lift people out of poverty. But such a conversion requires international cooperation and a common desire to address the climate cause. 

“The renewable energy sector created jobs employing 11 million people in 2019 and provided off-grid solutions, having helped bring the number of people with no access to electricity to under 1 billion,” the current president of the UN General Assembly Tiijani Muhammad-Bande of Nigeria told the audience. 

Today In: Business
While renewables are improving energy access and reducing inequities, they also have the potential to curb CO2 emissions globally. The goal is to shrink them by 45% by 2030 and 90% by 2050, with Canada's net-zero race highlighting the role of renewable energy in achieving those targets. Getting there, though, requires progressive government policies that will help to attract financing. 

According to IRENA, investment in the clean energy sector is now at $330 billion a year. But if the 2050 goals are to be reached, those levels must nearly double to $750 billion annually. The green energy sector does not want to compete with the oil and gas sectors but rather, it is seeking to diversify fuel sources — a strategy that could help make electricity systems more resilient to climate risks. To hit the Paris agreement’s targets, it says that renewable energy deployment must increase by a factor of six.  

To that end, IRENA is forming a “climate investment platform” that will bring ideas to the table and then introduce prospective parties. It will focus on those projects that it believes are “bankable.”

It’s about helping project developers find banks, private companies and pension funds to finance their worthy projects, IRENA Director General Francesco La Camera said in response to this reporter’s question. Moreover, he said that the platform would work to ensure there is a sound legal structure and that there is legislative support to “de-risk” the investments. 

“Overcoming investment needs for energy transformation infrastructure is one of the most notable barriers to the achievement of national goals,” La Camera says. “Therefore, the provision of capital to support the adoption of renewable energy is key to low-carbon sustainable economic development and plays a central role in bringing about positive social outcomes.”

If the monies are to flow into new projects, governments have to create an environment where innovation is to be rewarded: tax incentives for renewables along with the design and implementation of transition plans. The aim is to scale up which in turn, leads to new jobs and greater economic productivity — a payback of three-to-seven times the initial investment.  

The path of least resistance, for now, is off-grid green energy solutions, or providing electricity to rural areas by installing solar panels that may connect to localized microgrids. Africa, which has a half-billion people without reliable electricity, would benefit. However, “If you want to go to scale and have bankable projects, you have to be connected to the grid,” Moira Wahba, with the UN Development Program, told this writer. “That requires large capital and private enterprise.”

Public policy must thus work to create the knowledge base and the advocacy to help de-risk the investments. Government’s role is to reassure investors that they will not be subject to arbitrary laws or the crony allocation of contracts. Risk takers know there are no guarantees. But they want to compete on a level playing. 

Analyzing Risk Profiles

How do foreign investors square the role of utilities that are considered safe and sound with their potential expansion into new fields such as investing in carbon-free electricity and in new places? The elimination of risk is not possible, says Mohamed Jameel Al Ramahi, chief executive officer of UAE-based Masdar. But the need to decarbonize is paramount. The head of the renewable energy company says that every jurisdiction has its own risk profile but that each one must be fully transparent while also properly structuring their policies and regulations. And there needs to be insurance for political risks. 

The United States and China, for example, are already “de-risked,” because they are deploying “gigawatts of renewables,” he told this writer. “When we talk about doubling the amount of needed investment, we have to take into account the risk profile of the whole world. If it is a high-risk jurisdiction, it will be difficult to bring in foreign capital.” 

The most compelling factor that will drive investment is whether the global community can comply with the Paris agreement, says Dr. Thani Ahmed Al Zeyoudi, Minister of the Ministry of Climate Change and the Environment for the United Arab Emirates. The goal is to limit increases to 2 degrees Celsius by mid-century, with the understanding that the UN’s latest climate report emphasizes that positive results are urgently needed. 

One of the most effective mechanisms is the public-private model. Governments, for example, are signing long-term power purchase agreements, giving project developers the necessary income they need to operate, and in the EU plans to double electricity use by 2050 are reinforcing these commitments. They can also provide grants and bring in international partners such as the World Bank. 

“We are seeing the impact of climate change with the various extreme events: the Australian fires, the cyclones and the droughts,” the minister told reporters. “We can no longer pass this to future generations to deal with.” 

The United Arab Emirates is not just talking about it, adds Sultan Al Jabber, chief executive of Abu Dhabi’s national oil company, Adnoc, who is also the former head of subsidiary Masdar. It is acting now, and across Europe Big Oil is turning electric as traditional players pivot too. His comments came during Abu Dhabi’s Sustainability Week at the World Future Energy Summit. The country is “walking the walk” by investing in renewable projects around the globe and it is growing its own green energy portfolio. Addressing climate change is “right” while it is also making “perfect economic sense.” 

The green energy transition has taken root in advanced economies while it is making inroads in the developing world — a movement that has the twin effect of addressing climate change and creating economic opportunities, and one that aligns with calls to transform into a sustainable electric planet for long-term prosperity. But private investment must double, which requires proactive governments to limit unnecessary risks and to craft the incentives to attract risk-takers.

Six key trends that shaped Europe's electricity markets in 2020

European Electricity Market Trends 2020 highlight decarbonisation, rising renewables, EV adoption, shifting energy mix, COVID-19 impacts, fuel switching, hydro, wind and solar growth, gas price dynamics, and wholesale electricity price increases.

 

Key Points

EU power in 2020 saw lower emissions, more renewables, EV growth, demand shifts, and higher wholesale prices.

✅ Power sector CO2 down 14% on higher renewables, lower coal

✅ Renewables 39% vs fossil 36%; hydro, wind, solar expanded

✅ EV share hit 17%; wholesale prices rose with gas, ETS costs

 

According to the Market Observatory for Energy DG Energy report, the COVID-19 pandemic and favorable weather conditions are the two key drivers of the trends experienced within the European electricity market in 2020. However, the two drivers were exceptional or seasonal.

The key trends within Europe’s electricity market include:


1. Decrease in power sector’s carbon emissions

As a result of the increase in renewables generation and decrease in fossil-fueled power generation in 2020, the power sector was able to reduce its carbon footprint by 14% in 2020. The decrease in the sector’s carbon footprint in 2020 is similar to trends witnessed in 2019 when fuel switching was the main factor behind the decarbonisation trend.

However, most of the drivers in 2020 were exceptional or seasonal (the pandemic, warm winter, high
hydro generation). However, the opposite is expected in 2021, with the first months of 2021 having relatively cold weather, lower wind speeds and higher gas prices, with stunted hydro and nuclear output also cited, developments which suggest that the carbon emissions and intensity of the power sector could rise.

The European Union is targeting to completely decarbonise its power sector by 2050 through the introduction of supporting policies such as the EU Emissions Trading Scheme, the Renewable Energy Directive and legislation addressing air pollutant emissions from industrial installations, with expectations that low-emissions sources will cover most demand growth in the coming years.

According to the European Environment Agency, Europe halved its power sector’s carbon emissions in 2019 from 1990 levels.


2. Changes in energy consumption

EU consumption of electricity fell by -4% as majority of industries did not operate at full level during the first half of 2020. Although majority of EU residents stayed at home, meaning an increase in residential energy use, rising demand by households could not reverse falls in other sectors of the economy.

However, as countries renewed COVID-19 restrictions, energy consumption during the 4th quarter was closer to the “normal levels” than in the first three quarters of 2020. 

The increase in energy consumption in the fourth quarter of 2020 was also partly due to colder temperatures compared to 2019 and signs of surging electricity demand in global markets.


3. Increase in demand for EVs

As the electrification of the transport system intensifies, the demand for electric vehicles increased in 2020 with almost half a million new registrations in the fourth quarter of 2020. This was the highest figure on record and translated into an unprecedented 17% market share, more than two times higher than in China and six times higher than in the United States.

However, the European Environment Agency (EEA)argues that the EV registrations were lower in 2020 compared to 2019. EEA states that in 2019, electric car registrations were close to 550 000 units, having reached 300 000 units in 2018.


4. Changes in the region’s energy mix and increase in renewable energy generation

The structure of the region’s energy mix changed in 2020, according to the report.

Owing to favorable weather conditions, hydro energy generation was very high and Europe was able to expand its portfolio of renewable energy generation such that renewables (39%) exceeded the share of fossil fuels (36%) for the first time ever in the EU energy mix.

Rising renewable generation was greatly assisted by 29 GW of wind and solar capacity additions in 2020, which is comparable to 2019 levels. Despite disrupting the supply chains of wind and solar resulting in project delays, the pandemic did not significantly slow down renewables’ expansion.

In fact, coal and lignite energy generation fell by 22% (-87 TWh) and nuclear output dropped by 11% (-79 TWh). On the other hand, gas energy generation was not significantly impacted owing to favorable prices which intensified coal-to-gas and lignite-to-gas switching, even as renewables crowd out gas in parts of the market.


5. Retirement of coal energy generation intensify

 As the outlook for emission-intensive technologies worsens and carbon prices rise, more and more early coal retirements have been announced. Utilities in Europe are expected to continue transitioning from coal energy generation under efforts to meet stringent carbon emissions reduction targets and as they try to prepare themselves for future business models that they anticipate to be entirely low-carbon reliant.

6. Increase in wholesale electricity prices

In recent months, more expensive emission allowances, along with rising gas prices, have driven up wholesale electricity prices on many European markets to levels last seen at the beginning of 2019. The effect was most pronounced in countries that are dependent on coal and lignite. The wholesale electricity prices dynamic is expected to filter through to retail prices.

The rapid sales growth in the EVs sector was accompanied by expanding charging infrastructure. The number of high-power charging points per 100 km of highways rose from 12 to 20 in 2020.

Shopping for electricity is getting cheaper in Texas

Texas Electricity Prices are shifting as deregulation matures, with competitive market shopping lowering residential rates, narrowing gaps with regulated areas, and EIA data showing long term declines versus national averages across most Texans.

 

Key Points

Texas Electricity Prices are average residential rates in deregulated and regulated markets across the state.

✅ Deregulated areas saw 17.4% residential price declines since 2006

✅ Regulated zones experienced a 5.5% increase over the same period

✅ Competitive shopping narrowed the gap; Texas averaged below US

 

Shopping for electricity is becoming cheaper for most Texans, according to a new study from the Texas Coalition for Affordable Power. But for those who live in an area with only one electricity provider, prices have increased in a recent 10-year period, the study says.

About 85 percent of Texans can purchase electricity from a number of providers in a deregulated marketplace, while the remaining 15 percent must buy power from a single provider, often an electric cooperative, in their area.

The report from the Texas Coalition for Affordable Power, which advocates for cities and local governments and negotiates their power contracts, pulls information from the U.S. Energy Information Administration to compare prices for Texans in the two models. Most Texans could begin choosing their electricity provider in 2002.

Buying power tends to be more expensive for Texans who live in a part of the state with a deregulated electricity market. But that gap is continuing to shrink as Texans become more willing to shop for power, even as electricity complaints have periodically risen. In 2015, the gap “was the smallest since the beginning of deregulation,” according to the report.

Between 2006 and 2015, the last year for which data is available, average residential electric prices for Texans in a competitive market decreased by 17.4 percent, while average prices increased by 5.5 percent in the regulated areas, even as the Texas power grid has periodically faced stress.

“These residential price declines are promising, and show the retail electric market is maturing,” Jay Doegey, executive director for the Texas Coalition for Affordable Power, said in a statement. “We’re encouraged by the price declines, but more progress is needed.”

The study attributes the decline to the prevalence of “low-priced individual deals” in the competitive areas, while policymakers consider market reforms to bolster reliability.

Overall, the average price of electricity in Texas (which produces and consumes the most electricity in the U.S.) — including the price in the deregulated marketplace, for the third time in four years — was below the national average in 2015.

Ontario's Clean Electricity Regulations: Paving the Way for a Greener Future

Ontario Clean Electricity Regulations accelerate renewable energy adoption, drive emissions reduction, and modernize the smart grid with energy storage, efficiency targets, and reliability upgrades to support decarbonization and a stable power system for Ontario.

 

Key Points

Standards to cut emissions, grow renewables, improve efficiency, and modernize the grid with storage and smart systems.

✅ Phases down fossil generation and invests in storage.

✅ Sets utility efficiency targets to curb demand growth.

✅ Upgrades to smart grid for reliability and resiliency.

 

Ontario has taken a significant step forward in its energy transition with the introduction of new clean electricity regulations. These regulations, complementing federal Clean Electricity Regulations, aim to reduce carbon emissions, promote sustainable energy sources, and ensure a cleaner, more reliable electricity grid for future generations. This article explores the motivations behind these regulations, the strategies being implemented, and the expected impacts on Ontario’s energy landscape.

The Need for Clean Electricity

Ontario, like many regions around the world, is grappling with the effects of climate change, including more frequent and severe weather events. In response, the province has set ambitious targets to reduce greenhouse gas emissions and increase the use of renewable energy sources, reflecting trends seen in Alberta’s path to clean electricity across Canada. The electricity sector plays a central role in this transition, as it is responsible for a significant portion of the province’s carbon footprint.

For years, Ontario has been moving away from coal as a source of electricity generation, and now, with the introduction of these new regulations, the province is taking a step further in decarbonizing its grid, including its largest competitive energy procurement to date. By setting clear goals and standards for clean electricity, the province hopes to meet its environmental targets while ensuring a stable and affordable energy supply for all Ontarians.

Key Aspects of the New Regulations

The regulations focus on encouraging the use of renewable energy sources such as wind, solar, hydroelectric, and geothermal power. One of the key elements of the plan is the gradual phase-out of fossil fuel-based energy sources. This shift is expected to be accompanied by greater investments in energy storage solutions, including grid batteries, to address the intermittency issues often associated with renewable energy sources.

Ontario’s new regulations also emphasize the importance of energy efficiency in reducing overall demand. As part of this initiative, utilities and energy providers will be required to meet strict energy-saving targets and participate in new electricity auctions designed to reduce costs, ensuring that both consumers and businesses are incentivized to use energy more efficiently.

In addition, the regulations promote technological innovation in the electricity sector. By supporting the development of smart grids, energy storage technologies, and advanced power management systems, Ontario is positioning itself to become a leader in the global energy transition.

Impact on the Economy and Jobs

One of the anticipated benefits of the clean electricity regulations is their positive impact on Ontario’s economy. As the province invests in renewable energy infrastructure and clean technologies, new job opportunities are expected to arise in industries such as manufacturing, construction, and research and development. These regulations also encourage innovation in energy services, which could lead to the growth of new companies and industries, while easing pressures on industrial ratepayers through complementary measures.

Furthermore, the transition to cleaner energy is expected to reduce the long-term costs associated with climate change. By investing in sustainable energy solutions now, Ontario will help mitigate the financial burdens of environmental damage and extreme weather events in the future.

Challenges and Concerns

While the new regulations have been widely praised for their environmental benefits, they are not without their challenges. One of the primary concerns is the potential cost to consumers, and some Ontario hydro policy critique has called for revisiting legacy pricing approaches to improve affordability. While renewable energy sources have become more affordable over the years, transitioning from fossil fuels could still result in higher electricity prices in the short term. Additionally, the implementation of new technologies, such as smart grids and energy storage, will require substantial upfront investment.

Moreover, the intermittency of renewable energy generation poses a challenge to grid stability. Ontario’s electricity grid must be able to adapt to fluctuations in energy supply as more variable renewable sources come online. This challenge will require significant upgrades to the grid infrastructure and the integration of storage solutions to ensure reliable energy delivery.

The Road Ahead

Ontario’s clean electricity regulations represent an important step in the province’s commitment to combating climate change and transitioning to a sustainable, low-carbon economy. While there are challenges to overcome, the benefits of cleaner air, reduced emissions, and a more resilient energy system will be felt for generations to come. As the province continues to innovate and lead in the energy sector, Ontario is positioning itself to thrive in the green economy of the future.

This kite could harness more of the world's wind energy

Autonomous Energy Kites harness offshore wind on floating platforms, using carbon fiber wings, tethers, and rotors to generate grid electricity; an airborne wind energy solution backed by Alphabet's Makani to cut turbine costs.

 

Key Points

Autonomous Energy Kites are tethered craft that capture winds with rotors, generating grid power from floating platforms.

✅ Flies circles on tethers; rotors drive generators to feed the grid.

✅ Operates over deep-sea winds where fixed turbines are impractical.

✅ Lighter, less visual impact, and lower installation costs offshore.

 

One company's self-flying energy kite may be the answer to increasing wind power around the world, alongside emerging wave power solutions as well.

California-based Makani -- which is owned by Google's parent company, Alphabet -- is using power from the strongest winds found out in the middle of the ocean, where the offshore wind sector has huge potential, typically in spots where it's a challenge to install traditional wind turbines. Makani hopes to create electricity to power communities across the world.

Despite a growing number of wind farms in the United States and the potential of this energy source, lessons from the U.K. underscore how to scale, yet only 6% of the world's electricity comes from wind due to the the difficulty of setting up and maintaining turbines, according to the World Wind Energy Association.

When the company's co-founders, who were fond of kiteboarding, realized deep-sea winds were largely untapped, they sought to make that energy more accessible. So they built an autonomous kite, which looks like an airplane tethered to a base, to install on a floating platform in water, as part of broader efforts to harness oceans and rivers for power across regions. Tests are currently underway off the coast of Norway.

"There are many areas around the world that really don't have a good resource for renewable power but do have offshore wind resources," Makani CEO Fort Felker told Rachel Crane, CNN's innovation correspondent. "Our lightweight kites create the possibility that we could tap that resource very economically and bring renewable power to hundreds of millions of people."

This technology is more cost-efficient than a traditional wind turbine, which is a lot more labor intensive and would require lots of machinery and installation.

The lightweight kite, which is made of carbon fiber, has an 85-foot wingspan. The kite launches from a base station and is constrained by a 1,400-foot tether as it flies autonomously in circles with guidance from computers. Crosswinds spin the kite's eight rotors to move a generator that produces electricity that's sent back to the grid through the tether.

The kites are still in the prototype phase and aren't flown constantly right now as researchers continue to develop the technology. But Makani hopes the kites will one day fly 24/7 all year round. When the wind is down, the kite will return to the platform and automatically pick back up when it resumes.

Chief engineer Dr. Paula Echeverri said the computer system is key for understanding the state of the kite in real time, from collecting data about how fast it's moving to charting its trajectory.

Echeverri said tests have been helpful in establishing what some of the challenges of the system are, and the team has made adjustments to get it ready for commercial use. Earlier this year, the team successfully completed a first round of autonomous flights.

Working in deeper water provides an additional benefit over traditional wind turbines, according to Felker. By being farther offshore, the technology is less visible from land, and the growth of offshore wind in the U.K. shows how coastal communities can adapt. Wind turbines can be obtrusive and impact natural life in the surrounding area. These kites may be more attractive to areas that wish to preserve their scenic coastlines and views.

It's also desirable for regions that face constraints related to installing conventional turbines -- such as island nations, where World Bank support is helping developing countries accelerate wind adoption, which have extremely high prices for electricity because they have to import expensive fossil fuels that they then burn to generate electricity.

Makani isn't alone in trying to bring novelty to wind energy. Several others companies such as Altaeros Energies and Vortex Bladeless are experimenting with kites of their own or other types of wind-capture methods, such as underwater kites that generate electricity, a huge oscillating pole that generates energy and a blimp tethered to the ground that gathers winds at higher altitudes.

Hinkley C nuclear reactor roof lifted into place

Hinkley Point C dome lift marks a nuclear reactor milestone in Somerset, as EDF used Big Carl crane to place a 245-tonne steel roof, enabling 2027 startup amid costs, delays, and precision indoor welding.

 

Key Points

A 245-tonne dome lifted onto Hinkley Point C's first reactor, finishing the roof and enabling fit-out for a 2027 startup.

✅ 245-tonne steel dome lifted by Big Carl onto 44m-high reactor

✅ Indoor welding avoided weather defects seen at Flamanville

✅ Cost now £33bn; first power targeted by end of 2027

 

Engineers have lifted a steel roof onto a building which will house the first of two nuclear reactors at Hinkley Point in Somerset.

Hundreds of people helped with the delicate operation to get the 245-tonne steel dome into position.

It means the first reactor can be installed next year, ready to be switched on in June 2027.

Engineers at EDF said the "challenging job" was completed in just over an hour.

They first broke the ground on the new nuclear station in March 2017. Now, some 10,000 people work on what is Europe's largest building site.

Yet many analysts note that Europe is losing nuclear power even as demand for reliable energy grows.

They have faced delays from Covid restrictions and other recent setbacks, and the budget has doubled to £33bn, so getting the roof on the first of the two reactor buildings is a big deal.

EDF's nuclear island director Simon Parsons said it was a "fantastic night".

"Lifting the dome into place is a celebration of all the work done by a fantastic team. The smiles on people's faces this morning were something else.

"Now we can get on with the fitting of equipment, pipes and cables, including the first reactor which is on site and ready to be installed next year."

Nuclear minister Andrew Bowie hailed the "major milestone" in the building project, citing its role in the UK's green industrial revolution ambitions.

He said: "This is a key part of the UK Government's plans to revitalise nuclear."

But many still question whether Hinkley Point C will be worth all the money, especially after Hitachi's project freeze in Britain, with Roy Pumfrey of the Stop Hinkley campaign describing the project as "shockingly bad value".


Why lift the roof on?

The steel dome is bigger than the one on St Paul's Cathedral in London.

To lift it onto the 44-metre-high reactor building, they needed the world's largest land-based crane, dubbed Big Carl by engineers.

So why not just build the roof on top of the building?

The answer lies in a remote corner of Normandy in France, near a village called Flamanville.

EDF has been building a nuclear reactor there since 2007, ten years before they started in west Somerset.

The project is now a decade behind schedule and has still not been approved by French regulators.

Why? Because of cracks found in the precision welding on the roof of the reactor building.

In nuclear-powered France, they built the roof in situ, out in the open. 

Engineers have decided welding outside, exposed to wind and rain, compromised the high standards needed for a nuclear reactor.

So in Somerset they built a temporary workshop, which looks like a fair sized building itself. All the welding has been done inside, and then the completed roof was lifted into place.


Is it on time or on budget?

No, neither. When Hinkley C was first approved a decade ago, EDF said it would cost £14bn.

Four years later, in 2017, they finally started construction. By now the cost had risen to £19.5bn, and EDF said the plant would be finished by the end of 2025.

Today, the cost has risen to £33bn, and it is now hoped Hinkley C will produce electricity by the end of 2027.

"Nobody believes it will be done by 2027," said campaigner Roy Pumfrey.

"The costs keep rising, and the price of Hinkley's electricity will only get dearer," they added.

On the other hand, the increase in costs is not a problem for British energy bill payers, or the UK government.

EDF agreed to pay the full cost of construction, including any increases.

When I met Grant Shapps, then the UK Energy Secretary, at the site in April, he shrugged off the cost increases.

He said: "I think we should all be rather pleased it is not the British tax payer - it is France and EDF who are paying."

In return, the UK government agreed a set rate for Hinkley's power, called the Strike Price, back in 2013. The idea was this would guarantee the income from Hinkley Point for 35 years, allowing investors to get their money back.


Will it be worth the money?

Back in 2013, the Strike Price was set at £92.50 for each megawatt hour of power. At the time, the wholesale price of electricity was around £50/MWh, so Hinkley C looked expensive.

But since then, global shocks like the war in Ukraine have increased the cost of power substantially, and advocates argue next-gen nuclear could deliver smaller, cheaper, safer designs.
