✅ 10.2 billion yuan investment; final cascade plant on Wujiang in Chongqing

✅ Expected output: 1.76 billion kWh; capacity 525 MW; NDRC approval

✅ Improves river shipping; relocation of 5,000 residents in Wulong

China plans to build a 525-MW hydropower station on the Wujiang River, a tributary of the Yangtze River, in Southwest China's Chongqing municipality, aligning with projects like the Lawa hydropower station elsewhere in the Yangtze basin.

The Baima project, the last of a cascade of hydropower stations on the section of the Wujiang River in Chongqing, has gotten the green light from the National Development and Reform Commission, China's state planning agency, even as some independent power projects elsewhere face uncertainty, such as the Siwash Creek project in British Columbia, the Chongqing Municipal Commission of Development and Reform said Monday.

The project, in Baima township of Wulong district, is expected to involve an investment of 10.2 billion yuan ($1.6 billion), as China explores compressed air generation to bolster grid flexibility, it said.

AP1000 Refueling Outage Record showcases Westinghouse nuclear power excellence as Sanmen Unit 2 completes its first reactor refueling in 28.14 days, highlighting safety, reliability, outage optimization, and economic efficiency in China.

Key Points

It is the 28.14-day initial refueling at Sanmen Unit 2, a global benchmark achieved with Westinghouse AP1000 technology.

✅ 28.14-day first refueling at Sanmen Unit 2 sets global benchmark

✅ AP1000 design simplifies systems, improves safety and reliability

✅ Outage optimization by Westinghouse and CNNC accelerates schedules

Westinghouse Electric Company China operations today announced that Sanmen Unit 2, one of the world's first AP1000® nuclear power plants, has set a new refueling outage record in the global nuclear power industry, completing its initial outage in 28.14 days.

"Our innovative AP1000 technology allows for simplified systems and significantly reduces the amount of equipment, while improving the safety, reliability and economic efficiency of this nuclear power plant, reflecting global nuclear milestones reached recently," said Gavin Liu, president of the Westinghouse Asia Operating Plant Services Business. "We are delighted to see the first refueling outage for Sanmen Unit 2 was completed in less than 30 days. This is a great achievement for Sanmen Nuclear Power Company and further demonstrates the outstanding performance of AP1000 design."

All four units of the AP1000 nuclear power plants in China have completed their first refueling outages in the past 18 months, aligning with China's nuclear energy development momentum across the sector.  The duration of each subsequent outage has fallen significantly - from 46.66 days on the first outage to 28.14 days on Sanmen Unit 2.

"During the first AP1000 refueling outage at the Sanmen site in December 2019, a Westinghouse team of experts worked side-by-side with the Sanmen outage team to partner on outage optimization, and immediately set a new standard for a first-of-a-kind outage, while major refurbishments like the Bruce refurbishment moved forward elsewhere," said Miao Yamin, chairman of CNNC Sanmen Nuclear Power Company Limited. "Lessons learned were openly exchanged between our teams on each subsequent outage, which has built to this impressive achievement."

Westinghouse provided urgent technical support on critical issues during the outage, as international programs such as Barakah Unit 1 achieved key milestones, to help ensure that work was carried out on schedule with no impact to critical path.

In addition to the four AP1000 units in China, two units are under construction at the Vogtle expansion near Waynesboro, Georgia, USA.

Separately, in the United States, a new reactor startup underscored renewed momentum in nuclear generation this year.

Carbon Price Support, the UK carbon tax on power, slashed coal generation, cut CO2 emissions, boosted gas and imports via interconnectors, and signaled effective electricity market decarbonization across Great Britain and the EU.

Key Points

A UK power-sector carbon tax that drove coal off the grid, cut emissions, and shifted generation toward gas and imports.

✅ Coal generation fell from 40% to 3% in six years

✅ Rate rose to £18/tCO2 in 2015, boosting the coal-to-gas switch

✅ Added ~£39 to 2018 bills; imports via interconnectors eased prices

A tax on carbon dioxide emissions in Great Britain, introduced in 2013, has led to the proportion of electricity generated from coal falling from 40% to 3% over six years, a trend mirrored by global coal decline in power generation, according to research led by UCL.

British electricity generated from coal fell from 13.1 TWh (terawatt hours) in 2013 to 0.97 TWh in September 2019, and was replaced by other less emission-heavy forms of generation such as gas, as producers move away from coal in many markets. The decline in coal generation accelerated substantially after the tax was increased in 2015.

In the report, 'The Value of International Electricity Trading', researchers from UCL and the University of Cambridge also showed that the tax—called Carbon Price Support—added on average £39 to British household electricity bills, within the broader context of UK net zero policies shaping the energy transition, collecting around £740m for the Treasury, in 2018.

Academics researched how the tax affected electricity flows to connected countries and interconnector (the large cables connecting the countries) revenue between 2015—when the tax was increased to £18 per tonne of carbon dioxide—and 2018. Following this increase, the share of coal-fired electricity generation fell from 28% in 2015 to 5% in 2018, reaching 3% by September 2019. Increased electricity imports from the continent, alongside the EU electricity demand outlook across member states, reduced the price impact in the UK, and meant that some of the cost was paid through a slight increase in continental electricity prices (mainly in France and the Netherlands).

Project lead Dr. Giorgio Castagneto Gissey (Bartlett Institute for Sustainable Resources, UCL) said: "Should EU countries also adopt a high carbon tax we would likely see huge carbon emission reductions throughout the Continent, as we've seen in Great Britain over the last few years."

Lead author, Professor David Newbery (University of Cambridge), said: "The Carbon Price Support provides a clear signal to our neighbours of its efficacy at reducing CO2 emissions."

The Carbon Price Support was introduced in England, Scotland and Wales at a rate of £4.94 per tonne of carbon dioxide-equivalent and is now capped at £18 until 2021.The tax is one part of the Total Carbon Price, which also includes the price of EU Emissions Trading System permits and reflects global CO2 emissions trends shaping policy design.

Report co-author Bowei Guo (University of Cambridge) said: "The Carbon Price Support has been instrumental in driving coal off the grid, but we show how it also creates distortions to cross-border trade, making a case for EU-wide adoption."

Professor Michael Grubb (Bartlett Institute for Sustainable Resources, UCL) said: "Great Britain's electricity transition is a monumental achievement of global interest, and has also demonstrated the power of an effective carbon price in lowering dependence on electricity generated from coal."

The overall report on electricity trading also covers the value of EU interconnectors to Great Britain, measures the efficiency of cross-border electricity trading and considers the value of post-Brexit decoupling from EU electricity markets, setting these findings against the global energy transition underway.

Published today, the report annex focusing on the Carbon Price Support was produced by UCL to focus on the impact of the tax on British energy bills, with comparisons to Canadian climate policy debates informing grid impacts.

Canadian Clean Hydrogen is surging, driven by net-zero goals, tax credits, and exports. Fuel cells, electrolysis, and low-emissions power and transport signal growth, though current production is largely fossil-based and needs decarbonization.

Key Points

Canadian Clean Hydrogen is the shift to make and use low-emissions hydrogen for energy and industry to reach net-zero.

✅ $17B tax credits through 2035 to scale electrolyzers and hubs

✅ Export MOUs with Germany and the Netherlands target 2025 shipments

✅ IEA: 99% of hydrogen from fossil fuels; deep decarbonization needed

As the world races to find effective climate solutions, and toward an electric planet vision, hydrogen is earning buzz as a potentially low-emitting alternative fuel source. 

The promise of hydrogen as a clean fuel source is nothing new — as far back as the 1970s hydrogen was being promised as a "potential pollution-free fuel for our cars."

While hydrogen hasn't yet taken off as the fuel of the future  — a 2023 report from McKinsey & Company and the Hydrogen Council estimates that there is a grand total of eight hydrogen vehicle fuelling stations in Canada — many still hope that will change.

The hope is hydrogen will play a significant role in combating climate change, serving as a low-emissions substitute for fossil fuels in power generation, home heating and transportation, where cleaning up electricity remains critical, and today, interest in a Canadian clean hydrogen industry may be starting to bubble over.

"People are super excited about hydrogen because of the opportunity to use it as a clean chemical fuel. So, as a displacement for natural gas, diesel, gasoline, jet fuel," said Andrew Gillis, CEO of Canadian hydrogen company Aurora Hydrogen. 

Plans for low or zero-emissions hydrogen projects are beginning to take shape across the country. But, at the moment, hydrogen is far from a low-emissions fuel, which is why some experts suggest expectations for the resource should be tempered. 

The IEA report indicates that in 2021, global hydrogen production emitted 900 million tonnes of carbon dioxide — roughly 180 million more than the aviation industry — as roughly 99 per cent of hydrogen production came from fossil fuel sources. 

"There is a concern that the role of hydrogen in the process of decarbonization is being very greatly overstated," said Mark Winfield, professor of environmental and urban change at York University. 

A growing excitement 

In 2020, the government released a hydrogen strategy, aiming to "cement hydrogen as a tool to achieve our goal of net-zero emissions by 2050 and position Canada as a global, industrial leader of clean renewable fuels." 

The latest budget includes over $17 billion in tax credits between now and 2035 to help fund clean hydrogen projects.

Today, the most common application for hydrogen in Canada is as a material in industrial activities such as oil refining and ammonia, methanol and steel production, according to Natural Resources Canada. 

But, the buzz around hydrogen isn't exactly over its industrial applications, said Aurora Hydrogen's Gillis.

"All these sorts of things where we currently have emitting gaseous or liquid chemical fuels, hydrogen's an opportunity to replace those and access the energy without creating emissions at the point of us," Gillis said. 

When used in a fuel cell, hydrogen can produce electricity for transportation, heating and power generation without producing common harmful emissions like nitrogen oxide, hydrocarbons and particulate matter — BloombergNEF estimates that hydrogen could meet 24 per cent of global energy demand by 2050.

A growing industry

Canada's hydrogen strategy aims to have 30 per cent of end-use energy be from clean hydrogen by 2050. According to the strategy, Canada produces an estimated three million tonnes of hydrogen per year from natural gas today, but the strategy doesn't indicate how much hydrogen is produced from low-emissions sources.

In recent years, the Canadian clean hydrogen industry has earned international interest, especially as Germany's hydrogen strategy anticipates significant imports.

In 2021, Canada signed a memorandum of understanding with the Netherlands to help develop "export-import corridors for clean hydrogen" between the two countries. Canada also recently inked a deal with Germany to start exporting the resource there by 2025.

But while a low-emissions hydrogen plant went online in Becancour, Que., in 2021, the rest of Canada's clean-hydrogen industry seems to be in the early stages.

Electricity Security and Firm Capacity underpin reliable supply, balancing variable renewables with grid flexibility via gas plants, nuclear power, hydropower, battery storage, and demand response, safeguarding telework, e-commerce, and critical healthcare operations.

Key Points

Ability to meet demand by combining firm generation and flexible resources, keeping grids stable as renewables grow.

✅ Balances variable renewables with dispatchable generation

✅ Rewards flexibility via capacity markets and ancillary services

✅ Enhances grid stability for critical loads during low demand

The huge disruption caused by the coronavirus crisis, and the low-carbon electricity lessons drawn from it, has highlighted how much modern societies rely on electricity and how firm capacity, such as that provided by nuclear power, is a crucial element in ensuring supply, International Energy Agency (IEA) Executive Director Fatih Birol said.

In a commentary posted on LinkedIn, Birol said: "The coronavirus crisis reminds us of electricity's indispensable role in our lives. It's also providing insights into how that role is set to expand and evolve in the years and decades ahead."

Reliable electricity supply is crucial for teleworking, e-commerce, operating ventilators and other medical equipment, among all its other uses, he said, adding that the hundreds of millions of people who live without any access to electricity are far more vulnerable to disease and other dangers.

"Although new forms of short-term flexibility such as battery storage are on the rise, and initiatives like UK home virtual power plants are emerging, most electricity systems rely on natural gas power plants - which can quickly ramp generation up or down at short notice - to provide flexibility, underlining the critical role of gas in clean energy transitions," Birol said.

"Today, most gas power plants lose money if they are used only from time to time to help the system adjust to shifts in demand. The lower levels of electricity demand during the current crisis are adding to these pressures. Hydropower, an often forgotten workhorse of electricity generation, remains an essential source of flexibility.

"Firm capacity, including nuclear power in countries that have chosen to retain it as an option, is a crucial element in ensuring a secure electricity supply even as soaring electricity and coal use complicate transitions. Policy makers need to design markets that reward different sources for their contributions to electricity security, which can enable them to establish viable business models."

In most economies that have taken strong confinement measures in response to the coronavirus - and for which the IEA has available data - electricity demand has declined by around 15%, largely as a result of factories and businesses halting operations, and in New York City load patterns were notably reshaped during lockdowns. If electricity demand falls quickly while weather conditions remain the same, the share of variable renewables like wind and solar can become higher than normal, and low-emissions sources are set to cover almost all near-term growth.

"With weaker electricity demand, power generation capacity is abundant. However, electricity system operators have to constantly balance demand and supply in real time. People typically think of power outages as happening when surging electricity demand overwhelms supply. But in fact, some of the most high-profile blackouts in recent times took place during periods of low demand," Birol said.

"When electricity from wind and solar is satisfying the majority of demand, and renewables poised to eclipse coal by 2025 are reshaping the mix, systems need to maintain flexibility in order to be able to ramp up other sources of generation quickly when the pattern of supply shifts, such as when the sun sets. A very high share of wind and solar in a given moment also makes the maintenance of grid stability more challenging."

Iran Electricity Grid Synchronization enables regional interconnection, cross-border transmission, and Caspian-Europe energy corridors, linking Iraq, Azerbaijan, Russia, and Qatar to West Asia and European markets with reliable, flexible power exchange.

Key Points

Iran's initiative to link West Asian and European power grids for trade, transit, reliability, and regional influence.

✅ Synchronizes grids with Iraq, Azerbaijan, Russia, and potential Qatar link

✅ Enables east-to-Europe electricity transit via Caspian energy corridors

✅ Backed by gas-fueled and combined-cycle generation capacity

Following a plan for becoming West Asia’s electricity hub, Iran has been taking serious steps for joining its electricity network with neighbors in the past few years.

The Iranian Energy Ministry has been negotiating with the neighboring countries including Iraq for the connection of their power networks with Iran, discussing Iran-Iraq energy cooperation as well as ties with Russia, Afghanistan, Azerbaijan, and Qatar to make them enable to import or transmit their electricity to new destination markets through Iran.

The synchronization of power grids with the neighboring countries, not only enhances Iran’s electricity exchanges with them, but it will also increase the political stance of the country in the region.

So far, Iran’s electricity network has been synchronized with Iraq, where Iran is supplying 40% of Iraq's power today, and back in September, the Energy Minister Reza Ardakanian announced that the electricity networks of Russia and Azerbaijan are the next in line for becoming linked with the Iranian grid in the coming months.

“Within the next few months, the study project of synchronization of the electricity networks of Iran, Azerbaijan, and Russia will be completed and then the executive operations will begin,” the minister said.

Meanwhile, Ardakanian and Qatari Minister of State for Energy Affairs Saad Sherida Al-Kaabi held an online meeting in late September to discuss joining the two countries' electricity networks via sea.

During the online meeting, Al-Kaabi said: "Electricity transfer between the two countries is possible and this proposal should be worked on.”

Now, taking a new step toward becoming the region’s power hub, Iran has suggested becoming a bridge between East and Europe for transmitting electricity.

In a virtual conference dubbed 1st Caspian Europe Forum hosted by Berlin on Thursday, the Iranian energy minister has expressed the country’s readiness for joining its electricity network with Europe.

"We are ready to connect Iran's electricity network, as the largest power generation power in West Asia, with the European countries and to provide the ground for the exchange of electricity with Europe," Ardakanian said addressing the online event.

Iran's energy infrastructure in the oil, gas, and electricity sectors can be used as good platforms for the transfer of energy from east to Europe, he noted.

In the event, which was aimed to study issues related to the development of economic cooperation, especially energy, between the countries of the Caspian Sea region, the official added that Iran, with its huge energy resources and having skilled manpower and advanced facilities in the field of energy, can pave the ground for the prosperity of international transport and energy corridors.

"In order to help promote communication between our landlocked neighbors with international markets, as Uzbekistan aims to export power to Afghanistan across the region, we have created a huge transit infrastructure in our country and have demonstrated in practice our commitment to regional development and peace and stability," Ardakanian said.

He pointed out that having a major percentage of proven oil and gas resources in the world, regional states need to strengthen relations in a bid to regulate production and export policies of these huge resources and potentially play a role in determining the price and supply of these resources worldwide.

“EU countries can join our regional cooperation in the framework of bilateral or multilateral mechanisms such as ECO,” he said.

Given the growing regional and global energy needs and the insufficient investment in the field, with parts of Central Asia facing severe electricity shortages today, as well as Europe's increasing needs, this area can become a sustainable area of cooperation, he noted.

Ardakanian also said that by investing in energy production in Iran, Europe can meet part of its future energy needs on a sustainable basis.

In Iraq, plans for nuclear power plants are being pursued to tackle chronic electricity shortages, reflecting parallel efforts to diversify generation.

Iran currently has electricity exchange with Armenia, Azerbaijan, Iraq, where grid rehabilitation deals have been finalized, Turkmenistan, and Afghanistan.

The country’s total electricity exports vary depending on the hot and cold seasons of the year, since during the hot season which is the peak consumption period, the country’s electricity exports decreases, however electrical communication with neighboring countries continues.

Enjoying abundant gas resources, which is the main fuel for the majority of the country’s power plants, Iran has the capacity to produce about 85,500 megawatts [85.5 gigawatts (GW)] of electricity.

Currently, combined cycle power plants account for the biggest share in the country’s total power generation capacity as Iran is turning thermal plants to combined cycle to save energy, followed by gas power plants.
