Japan's prime minister said he instructed a utility to halt all three reactors at a power plant in central Japan because of safety concerns in the event of a major earthquake and tsunami.

Prime Minister Naoto Kan said the measure was to ensure safety, citing experts' forecast of a 90 per cent probability of a major quake striking the central region within 30 years.

The government has asked operator Chubu Electric Power Co. to suspend two running reactors and a third shut for a regular inspection at its coastal Hamaoka nuclear plant in Shizuoka, west of Tokyo.

“If an accident occurs at Hamaoka, it could create serious consequences,” Kan said.

Kan said the safety measure was made after the radiation crisis at the Fukushima Dai-ichi nuclear plant, which was crippled by an earthquake and tsunami March 11 that also left more than 25,000 people dead and missing on the northeast coast.

The Fukushima Dai-ichi nuclear plant lost its power and cooling systems, triggering fires, explosions and radiation leaks in the world's second-worst nuclear accident.

Radiation leaks from the Fukushima plant have forced 80,000 people living within a 20-kilometre radius to leave their homes. Many are staying in gymnasiums and community centres.

Residents in Shizuoka have long demanded suspension of the Hamaoka reactors.

Michigan Public Service Commission grants Consumers Energy request for more wind generation

Consumers Energy Wind Expansion gains MPSC approval in Michigan, adding up to 525 MW of wind power, including Gratiot Farms, while solar capacity requests face delays over cost projections under the renewable portfolio standard targets.

 

Key Points

A regulatory-approved plan enabling Consumers Energy to add 525 MW of wind while solar additions await cost review.

✅ MPSC approves up to 525 MW in new wind projects

✅ Gratiot Farms purchase allowed before May 1

✅ Solar request delayed over high cost projections

 

Consumers Energy Co.’s efforts to expand its renewable offerings gained some traction this week when the Michigan Public Service Commission (MPSC) approved a request for additional wind generation capacity.

Consumers had argued that both more wind and solar facilities are needed to meet the state’s renewable portfolio standard, which was expanded in 2016 to encompass 12.5 percent of the retail power of each Michigan electric provider. Those figures will continue to rise under the law through 2021 when the figure reaches 15 percent, alongside ongoing electricity market reforms discussions. However, Consumers’ request for additional solar facilities was delayed at this time due to what the Commission labeled unrealistically high-cost projections.

Consumers will be able to add as much as 525 megawatts of new wind projects amid a shifting wind market, including two proposed 175-megawatt wind projects slated to begin operation this year and next. Consumers has also been allowed to purchase the Gratiot Farms Wind Project before May 1.

The MPSC said a final determination would be made on Consumers’ solar requests during a decision in April. Consumers had sought an additional 100 megawatts of solar facilities, hoping to get them online sometime in 2024 and 2025.

Ireland: We are the global leaders in taking renewables onto the grid

Ireland 65% Renewable Grid Capability showcases world leading integration of intermittent wind and solar, smart grid flexibility, EU-SysFlex learnings, and the Celtic Interconnector to enhance stability, exports, and energy security across the European grid.

 

Key Points

Ireland can run its isolated power system with 65% variable wind and solar, informing EU grid integration and scaling.

✅ 65% system non-synchronous penetration on an isolated grid

✅ EU-SysFlex roadmap supports large-scale renewables integration

✅ Celtic Interconnector adds 700MW capacity and stability

 

Ireland is now able to cope with 65% of its electricity coming from intermittent electricity sources like wind and solar, as highlighted by Ireland's green electricity outlook today – an expertise Energy Minister Denish Naugthen believes can be replicated on a larger scale as Europe moves towards 50% renewable power by 2030.

Denis Naughten is an Irish politician who serves as Minister for Communications, Climate Action and Environment since May 2016.

Naughten spoke to editor Frédéric Simon on the sidelines of a EURACTIV event in the European  Parliament to mark the launch of EU-SysFlex, an EU-funded project, which aims to create a long-term roadmap for the large-scale integration of renewable energy on electricity grids.

What is the reason for your presence in Brussels today and the main message that you came to deliver?

The reason that I’m here today is that we’re going to share the knowledge what we have developed in Ireland, right across Europe. We are now the global leaders in taking variable renewable electricity like wind and solar onto our grid.

We can take a 65% loading on to the grid today – there is no other isolated grid in the world that can do that. We’re going to get up to 75% by 2020. This is a huge technical challenge for any electricity grid and it’s going to be a problem that is going to grow and grow across Europe, even as Europe's electricity demand rises in the coming years, as we move to 50% renewables onto our grid by 2030.

And our knowledge and understanding can be used to help solve the problems right across Europe. And the sharing of technology can mean that we can make our own grid in Ireland far more robust.

What is the contribution of Ireland when it comes to the debate which is currently taking place in Europe about raising the ambition on renewable energy and make the grid fit for that? What are the main milestones that you see looking ahead for Europe and Ireland?

It is a challenge for Europe to do this, but we’ve done it Ireland. We have been able to take a 65% loading of wind power on our grid, with Irish wind generation hitting records recently, so we can replicate that across Europe.

Yes it is about a much larger scale and yes, we need to work collaboratively together, reflecting common goals for electricity networks worldwide – not just in dealing with the technical solutions that we have in Ireland at the fore of this technology, but also replicating them on a larger scale across Europe.

And I believe we can do that, I believe we can use the learnings that we have developed in Ireland and amplify those to deal with far bigger challenges that we have on the European electricity grid.

Trialogue talks have started at European level about the reform of the electricity market. There is talk about decentralised energy generation coming from small-scale producers. Do you see support from all the member states in doing that? And how do you see the challenges ahead on a political level to get everyone on board on such a vision?

I don’t believe there is a political problem here in relation to this. I think there is unanimity across Europe that we need to support consumers in producing electricity for self-consumption and to be able to either store or put that back into the grid.

The issues here are more technical in nature. And how you support a grid to do that. And who actually pays for that. Ireland is very much a microcosm of the pan-European grid and how we can deal with those challenges.

What we’re doing at the moment in Ireland is looking at a pilot scheme to support consumers to generate their own electricity to meet their own needs and to be able to store that on site.

I think in the years to come a lot of that will be actually done with more battery storage in the form of electric vehicles and people would be able to transport that energy from one location to another as and when it’s needed. In the short term, we’re looking at some novel solutions to support consumers producing their own electricity and meeting their own needs.

So I think this is complex from a technical point of view at the moment, I don’t think there is an unwillingness from a political perspective to do it, and I think working with this particular initiative and other initiatives across Europe, we can crack those technical challenges.

To conclude, last year, the European Commission allocated €4 million to a project to link up the Irish electricity grid to France. How is that going to benefit Ireland? And is that related to worries that you may have over Brexit?

The plan, which is called the Celtic Interconnector, is to link France with the Irish electricity grid. It’s going to have a capacity of about 700MW. It allows us to provide additional stability on our grid and enables us to take more renewables onto the grid. It also allows us to export renewable electricity onto the main European grid as well, and provide stability to the French network.

So it’s a benefit to both individual networks as well as allowing far more renewables onto the grid. We’ve been working quite closely with RTE in France and with both regulators. We’re hoping to get the support of the European Commission to move it now from the design stage onto the construction stage. And I understand discussions are ongoing with the Commission at present with regard to that.

And that is going to diversify potential sources of electricity coming in for Ireland in a situation which is pretty uncertain because of Brexit, correct?

Well, I don’t think there is uncertainty because of Brexit in that we have agreements with the United Kingdom, we’re still going to be part of the broader energy family in relation to back-and-forth supply across the Irish Sea, with grid reinforcements in Scotland underscoring reliability needs.  But I think it is important in terms of meeting the 15% interconnectivity that the EU has set in relation to electricity.

And also in relation of providing us with an alternative support in relation to electricity supply outside of Britain. Because Britain is now leaving the European Union and I think this is important from a political point of view, and from a broader energy security point of view. But we don’t see it in the short term as causing threats in relation to security of supply.

Octopus Energy and Ukraine's DTEK enter Energy Talks

Octopus Energy and DTEK Partnership explores licensing the Kraken platform to rebuild Ukraine's power grid, enabling real-time analytics, smart-home integration, renewable energy orchestration, and distributed resilience amid ongoing attacks on critical energy infrastructure.

 

Key Points

Collaboration to deploy Kraken and renewables to modernize Ukraine's grid with analytics, smart control, and resilience.

✅ Kraken licensing for grid operations and customer analytics

✅ Shift to distributed solar, wind, and smart-home devices

✅ Real-time monitoring to mitigate outages and cyber risks

 

Octopus Energy, a prominent UK energy firm, has begun preliminary conversations with Ukraine's DTEK regarding potential collaboration to refurbish Ukraine's heavily damaged electric infrastructure as ongoing strikes threaten the power grid across the country.

Persistent assaults by Russia on Ukraine's power network, including a five-hour attack on Kyiv's grid, have led to significant electricity shortages in numerous regions.

Octopus Energy, the largest electricity and second-largest gas supplier in the UK, collaborates with energy firms in 17 countries using its Kraken software platform, and Ukraine joined Europe's power grid with unprecedented speed to bolster resilience. This platform is currently being trialled by the Abu Dhabi National Energy Company (Taqa) for power and water customers in the UAE.

A spokesperson from Octopus revealed to The National that the company is "in the early stages of discussions with DTEK to explore potential collaborative opportunities.”

One of the possibilities being considered is licensing Octopus's Kraken technology platform to DTEK, a platform that presently serves 54 million customer accounts globally.

Russian drone and missile attacks, which initially targeted Ukrainian ports and export channels last summer, shifted focus to energy infrastructure by October, ahead of the winter season as authorities worked to protect electricity supply before winter across the country.

These initial talks between Octopus CEO Greg Jackson and DTEK CEO Maxim Timchenko took place at the World Economic Forum in Davos, set against the backdrop of these ongoing challenges.

DTEK, Ukraine's leading private energy provider, might integrate Octopus's advanced Kraken software to manage and optimize data systems ranging from large power plants to smart-home devices, with a growing focus on protecting the grid against emerging threats.

Kraken is described by Octopus as a comprehensive technology platform that supports the entire energy supply chain, from generation to billing. It enables detailed analytics, real-time monitoring, and control of energy devices like heat pumps and electric vehicles, underscoring the need to counter cyber weapons that can disrupt power grids as systems become more connected.

Octopus Energy, with its focus on renewable sources, can also assist Ukraine in transitioning its power infrastructure from centralized coal-fired power stations, which are vulnerable targets, to a more distributed network of smaller solar and wind projects.

DTEK, serving approximately 3.5 million customers in the Kyiv, Donetsk, and Dnipro regions, is already engaged in renewable initiatives. The company constructed a wind farm in southern Ukraine within nine months last year and has plans for additional projects in Italy and Croatia.

Emphasizing the importance of rebuilding Ukraine's economy, Timchenko recently expressed at Davos the need for Ukrainian and international companies to work together to create a sustainable future for Ukraine, noting that incidents such as Russian hackers accessed U.S. control rooms highlight the urgency.

Affordable, safe' nuclear power is key to reaching Canada's climate goals: federal minister

Canada Nuclear Power Expansion highlights SMRs, clean energy, net-zero targets, and robust regulation to deliver safe, reliable baseload electricity, spur investment, and economically decarbonize remote communities, mines, and grids across provinces securely.

 

Key Points

Canada Nuclear Power Expansion grows SMRs and reactors to meet climate targets with safe, reliable baseload power.

✅ Deploys SMRs for remote communities, mines, and industrial sites

✅ Streamlines regulation to ensure safety, trust, and timely approvals

✅ Provides clean, reliable baseload to hit net-zero electricity goals

 

Canada must expand its nuclear power capacity if it is to reach its climate targets, according to Canadian Minister of Natural Resources Seamus Oregan.

Speaking to the Canadian Nuclear Association’s annual conference, Seamus O’Regan said the industry has to grow.

“As the world tackles a changing climate, nuclear power is poised to provide the next wave of clean, affordable, safe and reliable power,” he told a packed room.

The Ottawa conference was the largest the industry has run with dozens of companies and more than 900 people in attendance. Provincial cabinet ministers from Saskatchewan and Ontario were also there. Those two provinces, along with New Brunswick, signed a memorandum in December as part of a premiers' nuclear initiative to work together on small modular reactor technology.

People need to know that it’s safe

Small modular reactors are units that produce less power than large generating stations, but can be constructed easier and are expected to be safer to operate. Canadian firms have about a dozen of the proposed reactors working their way through the regulatory process, with New Brunswick's SMR plans drawing scrutiny.

The smaller reactors could be used in groups to replace large units, but the industry also hopes to use them in rural or isolated communities, mines or even oilsands projects, potentially replacing the diesel power generators some remote communities use.

The Canadian government issued a road map to support the industry in 2018 and O’Regan committed Thursday to putting some teeth on that proposal later this year, as provinces like Ontario explore new large-scale nuclear plants to meet demand, with specific steps the government will take.

“We have been working so hard to support this industry. We are placing nuclear energy front and centre, something that has never been done before.”

O’Regan said the government’s role is a clear, streamlined regulatory system that will promote the industry, but also help the Canadian public to trust the reactors will be safe.

“People need to know that it’s safe. They need to know that it’s regulated. They need to know that it’s safe for them,” he said.

The Liberals promised during the campaign that they would gradually reduce Canada’s carbon emissions even after hitting the targets in the Paris Agreement by 2030. By 2050, Prime Minister Justin Trudeau said he expects Canada to be carbon neutral, mindful of lessons from Europe's power crisis on reliability.

The government hasn’t outlined how it will achieve that goal. O’Regan said more detail is coming, but it’s clear that nuclear is going to have to play a major part, echoing the UK’s green industrial revolution approach to reactor deployment.

“I have not seen a credible plan for net zero without nuclear as part of the mix. I don’t think we are going to be relying on any one technology. I think it’s going to be a whole host of things.”

O’Regan said large investors are looking for countries that are on the path to net zero.

“Everybody has their shirt sleeves rolled up and we know we need to work on this, not only do we have to work on this for the urgency of the planet, but we have to work on it for Canadian jobs.”

He added, “We must focus on those areas where Canada can and should lead, like nuclear.”

Canadians are ready to take a fresh look at nuclear

John Gorman, president of the Canadian Nuclear Association, said he was thrilled with O’Regan’s comments.

“I took the minister’s remarks this morning as being perhaps the strongest language of support for the nuclear industry in a number of years.”

Gorman said the industry is in strong shape and is working with utility companies such as Ontario Power Generation and regulators to move projects forward.

“It’s this amazing collaboration and coordination that is enabling us to beat others to the roll out of these small modular reactors,” he said.

He said provinces that might not have looked at nuclear before now have an incentive to do it, because of climate change. A former solar industry executive, Gorman said solar and wind power are important, as Ontario plans to seek new wind and solar power to ease supply pressures, but they won’t be able to keep up with rising power demands.

“Globally we are seeing increased recognition that climate change is real and that it’s a crisis, we are also seeing recognition that we are not making as much progress on decarbonizing our electricity system as we thought,” he said. “Canadians are ready to take a fresh look at nuclear and see the real facts.”

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.

How Ukraine Will Keep the Lights On This Winter

Ukraine Winter Energy Strategy strengthens the power grid through infrastructure repairs, electricity imports, renewable integration, nuclear output, and conservation to ensure reliable heating, blackout mitigation, and grid resilience with international aid, generators, and transmission lines.

 

Key Points

A wartime plan to stabilize Ukraine's grid via repairs, imports, renewables, and nuclear to deliver reliable electricity.

✅ Repairs, imports, and demand management stabilize the grid.

✅ Renewables and nuclear reduce outage risks in winter.

✅ International aid supplies transformers, generators, expertise.

 

As Ukraine braces for the winter months, the question of how the country will keep the lights on has become a pressing concern, as the country fights to keep the lights on amid ongoing strikes. The ongoing war with Russia has severely disrupted Ukraine's energy infrastructure, leading to widespread damage to power plants, transmission lines, and other critical energy facilities. Despite these challenges, Ukraine has been working tirelessly to maintain its energy supply during the cold winter months, which are essential not only for heating but also for the functioning of homes, businesses, hospitals, and schools. Here's a closer look at the steps Ukraine is taking to keep the lights on this winter and ensure that its people have access to reliable electricity.

1. Repairing Damaged Infrastructure

One of the most immediate concerns for Ukraine's energy sector is the extensive damage inflicted on its power infrastructure by Russian missile and drone attacks. Since the war began in 2022, Ukraine has faced repeated attacks targeting power plants, substations, and power lines, including strikes on western regions that caused widespread outages across communities. These attacks have left parts of the country with intermittent or no electricity, and repairing the damage has been a monumental task.

However, Ukraine has made significant progress in restoring its energy infrastructure. Government agencies and energy companies have been working around the clock to repair power plants and transmission networks. Teams of technicians and engineers have been deployed to restore power to areas that have been hardest hit by Russian attacks, often under difficult and dangerous conditions. While some areas may continue to face outages, efforts to rebuild the energy grid are ongoing, with the government prioritizing critical infrastructure to ensure that hospitals, military facilities, and essential services have access to power.

2. Energy Efficiency and Conservation Measures

To cope with reduced energy availability and avoid overloading the grid, Ukrainian authorities have been encouraging energy efficiency and conservation measures. These efforts are particularly important during the winter when demand for electricity and heating is at its peak.

The government has implemented energy-saving programs, urging citizens and businesses to reduce their consumption and adopt new energy solutions that can be deployed quickly. Measures include limiting electricity use during peak hours, setting thermostats lower in homes and businesses, and encouraging the use of energy-efficient appliances. Ukrainian officials have also been promoting public awareness campaigns to educate people about the importance of energy conservation, which is crucial to avoid grid overload and ensure the distribution of power across the country.

3. Importing Energy from Abroad

To supplement domestic energy production, Ukraine has been working to secure electricity imports from neighboring countries. Ukraine has long been interconnected with energy grids in countries such as Poland, Slovakia, and Hungary, which allows it to import electricity during times of shortage. In recent months, Ukraine has ramped up efforts to strengthen these connections, ensuring that it can import electricity when domestic production is insufficient to meet demand, and in a notable instance, helped Spain during blackouts through coordinated cross-border support.

While electricity imports from neighboring countries provide a temporary solution, this is not without its challenges. The cost of importing electricity can be high, and the country’s ability to import large amounts of power depends on the availability of energy in neighboring nations; officials say there are electricity reserves and no scheduled outages if strikes do not resume. Ukraine has been actively seeking new energy partnerships and working with international organizations to secure access to electricity, including exploring the potential for importing energy from the European Union.

4. Harnessing Renewable Energy Sources

Another key part of Ukraine's strategy to keep the lights on this winter is tapping into renewable energy sources, particularly wind and solar power. While Ukraine’s energy sector has historically been dependent on fossil fuels, the country has been making strides in integrating renewable energy into its grid. Solar and wind energy are particularly useful in supplementing the national grid, especially during the winter months when demand is high.

Renewable energy sources are less vulnerable to missile strikes compared to traditional power plants, making them an attractive option for Ukraine's energy strategy. Although renewable energy currently represents a smaller portion of Ukraine’s overall energy mix, its contribution is expected to increase as the country invests more in clean energy infrastructure. In addition to reducing dependence on fossil fuels, this shift is aligned with Ukraine’s broader environmental goals and will be important for the long-term sustainability of its energy sector.

5. International Aid and Support

International support has been crucial in helping Ukraine keep the lights on during the war. Western allies, including the European Union and the United States, have provided financial assistance, technical expertise, and equipment to help restore the energy infrastructure, though Washington recently ended some grid restoration support as priorities shifted. In addition to rebuilding power plants and transmission lines, Ukraine has received advanced energy technologies and materials to strengthen its energy security.

The U.S. has sent electrical transformers, backup generators, and other essential equipment to help Ukraine restore its energy grid. The European Union has also provided both financial and technical assistance, supporting Ukraine’s efforts to integrate more renewable energy into its grid and enhancing the country’s ability to import electricity from neighboring states.

6. The Role of Nuclear Energy

Ukraine’s nuclear energy plants play a critical role in the country’s electricity supply. Before the war, nuclear power accounted for around 50% of Ukraine’s total electricity generation, and for communities near the front line, electricity is civilization that depends on reliable baseload. Despite the ongoing conflict, Ukrainian nuclear plants have remained operational, though they face heightened security risks due to the proximity of active combat zones.

In the winter months, nuclear plants are expected to continue providing a significant portion of Ukraine's electricity, which is essential for meeting the country's heating and power needs. The government has made efforts to ensure the safety and security of these plants, which remain a vital part of the country's energy strategy.

Keeping the lights on in Ukraine during the winter of 2024 is no small feat, given the war-related damage to energy infrastructure, rising energy demands, and ongoing security risks. However, the Ukrainian government has taken proactive steps to address these challenges, including repairing critical infrastructure, importing energy from neighboring countries, promoting energy efficiency, and expanding renewable energy sources. International aid and the continued operation of nuclear plants also play a vital role in ensuring a reliable energy supply. While challenges remain, Ukraine’s resilience and determination to overcome its energy crisis are clear, and the country is doing everything it can to keep the lights on through this difficult winter.
