Duke Energy plans to build between 100 and 400 electricity-generating mini solar power plants throughout North Carolina over the next two years that will include panel installations at manufacturing facilities, the company said.

The North Carolina Utilities Commission has permitted Duke Energy to proceed with its $50 million proposal to install solar panels on the roofs and grounds of homes, schools, office buildings, shopping malls, warehouses and industrial plants, starting later this year.

Collectively, the solar sites will generate enough electricity to power 1,300 homes, the company said. The electricity will flow directly from the solar sites to the electrical grid that serves all customers.

Duke Energy touts the solar initiative as one of the nation's first and largest demonstrations of distributed generation, in which electricity is produced at numerous micro generating sites rather than at a large, centralized, traditional power plant.

"We are redefining our boundaries. We're looking ahead and we're looking around the corner," CEO Jim Rogers told shareholders attending the company's annual meeting. "We believe the future is a low-carbon world. The 21st century mission of our company is to decarbonize our energy supply and provide universal access to energy efficiency."

Duke Energy will own and maintain the solar panels during their expected 25-year lifespan. The company also will own the electricity generated.

It will pay a rental fee to property owners who host the panels for use of their roofs or land, based on the size of the installation and amount of electricity generated at any given site.

Opinion: Nuclear Beyond Electricity

Nuclear decarbonization leverages low-carbon electricity, process heat, and hydrogen from advanced reactors and SMRs to electrify industry, buildings, and transport, supporting net-zero strategies and grid flexibility alongside renewables with dispatchable baseload capacity.

 

Key Points

Nuclear decarbonization uses reactors to supply low-carbon power, heat, and hydrogen, cutting emissions across industry.

✅ Advanced reactors and SMRs enable high-temperature process heat

✅ Nuclear-powered electrolysis and HTSE produce low-carbon hydrogen

✅ District heating from reactors reduces pollution and coal use

 

By Dr Henri Paillere, Head of the Planning and Economics Studies Section of the IAEA

Decarbonising the power sector will not be sufficient to achieving net-zero emissions, with assessments indicating nuclear may be essential across sectors. We also need to decarbonise the non-power sectors - transport, buildings and industry - which represent 60% of emissions from the energy sector today. The way to do that is: electrification with low-carbon electricity as much as possible; using low-carbon heat sources; and using low-carbon fuels, including hydrogen, produced from clean electricity.
The International Energy Agency (IEA) says that: 'Almost half of the emissions reductions needed to reach net zero by 2050 will need to come from technologies that have not reached the market today.' So there is a need to innovate and push the research, development and deployment of technologies. That includes nuclear beyond electricity.

Today, most of the scenario projections see nuclear's role ONLY in the power sector, despite ongoing debates over whether nuclear power is in decline globally, but increased electrification will require more low-carbon electricity, so potentially more nuclear. Nuclear energy is also a source of low-carbon heat, and could also be used to produce low-carbon fuels such as hydrogen. This is a virtually untapped potential.

There is an opportunity for the nuclear energy sector - from advanced reactors, next-gen nuclear small modular reactors, and non-power applications - but it requires a level playing field, not only in terms of financing today's technologies, but also in terms of promoting innovation and supporting research up to market deployment. And of course technology readiness and economics will be key to their success.

On process heat and district heating, I would draw attention to the fact there have been decades of experience in nuclear district heating. Not well spread, but experience nonetheless, in Russia, Hungary and Switzerland. Last year, we had two new projects. One floating nuclear power plant in Russia (Akademik Lomonosov), which provides not only electricity but district heating to the region of Pevek where it is connected. And in China, the Haiyang nuclear power plant (AP1000 technology) has started delivering commercial district heating. In China, there is an additional motivation to reducing emissions, namely to cut air pollution because in northern China a lot of the heating in winter is provided by coal-fired boilers. By going nuclear with district heating they are therefore cutting down on this pollution and helping with reducing carbon emissions as well. And Poland is looking at high-temperature reactors to replace its fleet of coal-fired boilers and so that's a technology that could also be a game-changer on the industry side.

There have also been decades of research into the production of hydrogen using nuclear energy, but no real deployment. Now, from a climate point of view, there is a clear drive to find substitute fuels for the hydrocarbon fuels that we use today, and multiple new nuclear stations are seen by industry leaders as necessary to meet net-zero targets. In the near term, we will be able to produce hydrogen with electrolysis using low-carbon electricity, from renewables and nuclear. But the cheapest source of low-carbon power is from the long-term operation of existing nuclear power plants which, combined with their high capacity factors, can give the cheapest low-carbon hydrogen of all.

In the mid to long term, there is research on-going with processes that are more efficient than low-temperature electrolysis, which is high temperature steam electrolysis or thermal splitting of water. These may offer higher efficiencies and effectiveness but they also require advanced reactors that are still under development. Demonstration projects are being considered in several countries and we at the IAEA are developing a publication that looks into the business opportunities for nuclear production of hydrogen from existing reactors. In some countries, there is a need to boost the economics of the existing fleet, especially in the electricity systems where you have low or even negative market prices for electricity. So, we are looking at other products that have higher values to improve the competitiveness of existing nuclear power plants.

The future means not only looking at electricity, but also at industry and transport, and so integrated energy systems. Electricity will be the main workhorse of our global decarbonisation effort, but through heat and hydrogen. How you model this is the object of a lot of research work being done by different institutes and we at the IAEA are developing some modelling capabilities with the objective of optimising low-carbon emissions and overall costs.

This is just a picture of what the future might look like: a low-carbon power system with nuclear lightwater reactors (large reactors, small modular reactors and fast reactors) drawing on the green industrial revolution reactor waves in planning; solar, wind, anything that produces low-carbon electricity that can be used to electrify industry, transport, and the heating and cooling of buildings. But we know there is a need for high-temperature process steam that electricity cannot bring but which can be delivered directly by high-temperature reactors. And there are a number of ways of producing low-carbon hydrogen. The beauty of hydrogen is that it can be stored and it could possibly be injected into gas networks that could be run in the future on 100% hydrogen, and this could be converted back into electricity.

So, for decarbonising power, there are many options - nuclear, hydro, variable renewables, with renewables poised to surpass coal in global generation, and fossil with carbon capture and storage - and it's up to countries and industries to invest in the ones they prefer. We find that nuclear can actually reduce the overall cost of systems due to its dispatchability and the fact that variable renewables have a cost because of their intermittency. There is a need for appropriate market designs and the role of governments to encourage investments in nuclear.

Decarbonising other sectors will be as important as decarbonising electricity, from ways to produce low-carbon heat and low-carbon hydrogen. It's not so obvious who will be the clear winners, but I would say that since nuclear can produce all three low-carbon vectors - electricity, heat and hydrogen - it should have the advantage.
We at the IAEA will be organising a webinar next month with the IEA looking at long-term nuclear projections in a net-zero world, building on IAEA analysis on COVID-19 and low-carbon electricity insights. That will be our contribution from the point of view of nuclear to the IEA's special report on roadmaps to net zero that it will publish in May.

EDF and France reach deal on electricity prices-source

EDF Nuclear Power Price Deal sets a 70 euros/MWh reference price, adds consumer protection if wholesale electricity prices exceed 110 euros/MWh, and outlines taxation mechanisms to shield bills while funding nuclear investment.

 

Key Points

A government-EDF deal setting 70 euros/MWh with safeguards above 110 euros/MWh to protect consumers.

✅ Reference price fixed at 70 euros/MWh, near EDF costs.

✅ Consumer shield above 110 euros/MWh; up to 90% extra-revenue tax.

✅ Review clauses maintain 70 euros/MWh through market swings.

 

State-controlled power group EDF and the French government have reached a tentative deal on future nuclear power prices, echoing a new electricity pricing scheme France has floated, a source close to the government said on Monday, ending months of tense negotiations.

The two sides agreed on 70 euros per megawatt hour (MWH) as a reference level for power prices, aligning with EU plans for more fixed-price contracts for consumers, the source said, cautioning that details of the deal are still being finalised.

The negotiations aimed to find a compromise between EDF, which is eager to maximise revenues to fund investments, and the government, keen to keep electricity bills for French households and businesses as low as possible, amid ongoing EU electricity reform debates across the bloc.

EDF declined to comment.

The preliminary deal sets out mechanisms that would protect consumers if power market prices rise above 110 euros/MWH, similar to potential emergency electricity measures being weighed in Europe, the source said, adding that the deal also includes clauses that would provide a price guarantee for EDF.

The 70 euros/MWH agreed reference price level is close to EDF's nuclear production costs, as Europe moves to revamp its electricity market more broadly. The nuclear power produced by the company provides 70% of France's electricity.

The agreement would allow the government to tax EDF's extra revenues at 90% if prices surpass 110 euros/MWH, in order to offset the impact on consumers. It would also enable a review of conditions in case of market fluctuations to safeguard the 70 euro level for EDF, reflecting how rolling back electricity prices is tougher than it appears, the source said.

French wholesale electricity prices are still above 100 euros/MWH, after climbing to 1,200 euros during last year's energy crisis, even as diesel prices have returned to pre-conflict levels.

A final agreement should be officially announced on Tuesday after a meeting between Finance Minister Bruno Le Maire, Energy Transition Minister Agnes Pannier-Runacher and EDF chief Luc Remont.

That meeting will work out the final details on price thresholds and tax rates between the reference level and the upper limit, the source said.

Negotiations between the two sides were so fraught that at one stage they raised questions about the future of EDF chief Luc Remont, who was appointed by President Emmanuel Macron a year ago to turn around EDF.

The group ended 2022 with a 18 billion-euro loss and almost 65 billion euros of net debt, hurt by a record number of reactor outages that coincided with soaring energy prices in the wake of Russia's invasion of Ukraine.

With its output at a 30-year low, EDF was forced to buy electricity on the market to supply customers. The government, meanwhile, imposed a cap on electricity prices, leaving EDF selling power at a discount.

Bitcoin mining uses so much electricity that 1 city could curtail facility's power during heat waves

Medicine Hat Bitcoin Mining Facility drives massive electricity demand and energy use, leveraging natural gas and nearby wind power; Hut 8 touts economic growth, while critics cite carbon emissions, renewables integration, and climate impact.

 

Key Points

A Hut 8 project in Alberta that mines bitcoin at scale, consuming up to 60 MW and impacting energy and emissions.

✅ Consumes more than 60 MW, rivaling citywide electricity use

✅ Sited by natural gas plant; wind turbines nearby

✅ Economic gains vs. carbon emissions and climate risks

 

On the day of the grand opening of the largest bitcoin mining project in the country, the weather was partly cloudy and 15 C. On a Friday afternoon like this one, the new facility uses as much electricity as all of Medicine Hat, Alta., a city of more than 60,000 people and home to several large industrial plants.

The vast amount of electricity needed for bitcoin mining is why the city of Medicine Hat has championed the economic benefits of the project, while environmentalists say they are wary of the significant energy use.

Toronto-based Hut 8 has spent more than $100 million to develop the 4½-hectare site on the northern edge of the city. It has 56 shipping containers, each filled with 180 computer servers that digitally mine for bitcoin around the clock.

The company said it has already mined more than 3,300 bitcoins in Alberta, including at its much smaller site in Drumheller. On average, the Medicine Hat facility mines about 20 bitcoins per day. The value of bitcoin can fluctuate daily, but has sold recently for around $9,000.

The bitcoin mining facility is located right beside the city of Medicine Hat's new natural gas-fired power plant and four wind turbines are a short distance away. The bitcoin plant can consume more than 60 megawatts of power, more than 10 times more electricity used by any other facility in the city, according to the mayor.

That's why, in the event of a summer heat wave, the city has provisions in place to pull the plug on the electricity it provides to Hut 8, mirroring utility pauses on crypto loads seen elsewhere, so there won't be any blackouts for residents, according to the mayor.

Still, some say the bitcoin mining industry wastes far too much energy

"It's a huge magnitude when you talk about the carbon emissions," said Saeed Kaddoura, an analyst with the Pembina Institute, an environmental think-tank. "Moving forward, there needs to be some consideration on what the environmental impact of this is."

Medicine Hat owns its own natural gas and electricity generation and distribution businesses. The city leases the land to Hut 8 and the facility employs 40 full-time workers. Add up the economic benefits and the city of Medicine Hat will receive a significant financial boost from the new project, says Ted Clugston, the city's mayor.

Financial details of the city's deal with Hut 8 are not disclosed.

For more than a century, the city has attracted business by offering low-cost energy, and the mayor said this project is no different.

"They could have gone anywhere in the world and they chose Medicine Hat," said Clugston. "[Hut 8] is not here for renewable energy because it is not reliable. They need gas-fired generation and we have it in spades."

Environmental groups are concerned by the sheer amount of energy consumed by bitcoin mining, with some utilities warning they can't serve new energy-intensive customers right now, especially in places like Medicine Hat where most of the electricity is produced by fossil fuels.

The bitcoin system is designed, so only a limited number of the cryptocurrency can be mined everyday. Over time, as more miners compete for a decreasing number of available bitcoins, facilities will have to use more electricity compared to the amount of the cryptocurrency they collect.

"The way the bitcoin algorithm works is that it's designed to waste as much electricity as possible. And the more popular bitcoin becomes, the more electricity it wastes," said Keith Stewart, a spokesperson for Greenpeace.

Stewart questions whether natural gas should be used to produce a digital product.

"If you live in Alberta, you want to have heat and light, those types of things. I don't think bitcoin is a necessity of life for anyone," he said.

The CEO of Hut 8 completely disagrees, arguing the cryptocurrency is essential.  

"Bitcoin was created during the financial crisis. It has really served a purpose in terms of providing the opportunity for people who don't necessarily trust their government or their central banks," said Andrew Kiguel.

Ontario to Rely on Battery Storage to Meet Rising Energy Demand

Ontario Battery Energy Storage anchors IESO strategy, easing peak demand and boosting grid reliability. Projects like Oneida BESS (250MW) and nearly 3GW procurements integrate renewables, wind and solar, enabling flexible, decarbonized power.

 

Key Points

Provincewide grid batteries help IESO manage peaks, integrate renewables, and strengthen reliability across Ontario.

✅ IESO forecasts 1,000MW peak growth by 2026

✅ Oneida BESS adds 250MW with 20-year contract

✅ Nearly 3GW storage procured via LT1 and other RFPs

 

Ontario’s electricity grid is facing increasing demand amid a looming supply crunch, prompting the province to invest heavily in battery energy storage systems (BESS) as a key solution. The Ontario Independent Electricity System Operator (IESO) has highlighted that these storage technologies will be crucial for managing peak demand in the coming years.

Ontario's energy demands have been on the rise, driven by factors such as population growth, electric vehicle manufacturing, data center expansions, and heavy industrial activity. The IESO's latest assessment, and its work on enabling storage, covering the period from April 2025 to September 2026, indicates that peak demand will increase by approximately 1,000MW between the summer of 2025 and 2026. This forecasted rise in energy use is attributed to the acceleration of various sectors within the province, underscoring the need for reliable, scalable energy solutions.

A significant portion of this solution will be met by large-scale energy storage projects. Among the most prominent is the Oneida BESS, a flagship project that will contribute 250MW of storage capacity. This project, developed by a consortium including Northland Power and NRStor, will be located on land owned by the Six Nations of the Grand River. Expected to be operational soon, it will play a pivotal role in ensuring grid stability during high-demand periods. The project benefits from a 20-year contract with the IESO, guaranteeing payments that will support its financial viability, alongside additional revenue from participating in the wholesale energy market.

In addition to Oneida, Ontario has committed to acquiring nearly 3GW of energy storage capacity through various procurement programs. The 2023 Expedited Long-Term 1 (LT1) request for proposals (RfP) alone secured 881MW of storage, with additional projects in the pipeline. A notable example is the Hagersville Battery Energy Storage Park, which, upon completion, will be the largest such project in Canada. The success of these procurement efforts highlights the growing importance of BESS in Ontario's energy strategy.

The IESO’s proactive approach to energy storage is not only a response to rising demand but also a step toward decarbonizing the province’s energy system. As Ontario transitions away from traditional fossil fuels, BESS will provide the necessary flexibility to accommodate increasing renewable energy generation, a clean energy solution widely recognized in jurisdictions like New York, particularly from intermittent sources like wind and solar. By storing excess energy during periods of low demand and dispatching it when needed, these systems will help maintain grid stability, and as many utilities see benefits even without mandates, reduce reliance on fossil fuel-based power plants.

Looking ahead, Ontario's energy storage capacity is expected to grow significantly, complemented by initiatives such as the Hydrogen Innovation Fund, with projects from the 2023 LT1 RfP expected to come online by 2027. As more storage resources are integrated into the grid, the province is positioning itself to meet its rising energy needs while also advancing its environmental goals.

Ontario’s increasing reliance on battery energy storage is a clear indication of the province’s commitment to a sustainable and resilient energy future, aligning with perspectives from Sudbury sustainability advocates on the grid's future. With substantial investments in storage technology, Ontario is not only addressing current energy challenges but also paving the way for a cleaner, more reliable energy system in the years to come.

Electricity prices may go up by 15 per cent

Jersey Electricity Standby Charge proposes a grid-backup fee for commercial self-generators of renewable energy, with a review delaying implementation; potential tariff impacts include 10-15 percent price rises, cost recovery, and network reliability.

 

Key Points

A grid-backup fee for Jersey self-generating businesses to share network costs fairly and curb electricity price rises.

✅ Applies to commercial self-generation using renewables or not

✅ Excludes full exporters and pre-charge installations

✅ Aims to recover grid costs and avoid 10-15% price rises

 

Electricity prices could rise by ten to 15 per cent if a standby charge for some commercial customers is not implemented, the chief executive of Jersey Electricity has warned.

Jersey Electricity has proposed extending a monthly fee to commercial customers who generate their own power through renewable means but still wish to be connected to Jersey’s grid as a back-up, echoing Ontario energy storage efforts to shore up reliability.

The States recently unanimously backed a proposal lodged by Deputy Carolyn Labey to delay administering the levy until a review could be carried out, as seen in the UK grid's net-zero transformation debates influencing policy. The charge, was due to be implemented next month but will now not be introduced until May, or later if the review has not concluded.

But Chris Ambler, JE chief executive, warned that failing to implement the standby charge could lead to additional costs for customers.

Some of JE’s commercial customers have already been charged a standby fee after generating their own power through non-renewable means.

The charge does not apply to businesses which export all of their electricity back into the system as part of a buy-back scheme or those which install self-generation facilities before the charge is implemented.

Deputy Labey argued that the Island had done ‘absolutely nothing’ to support the use of renewable energies and instead were discouraging locally generated power by allowing JE to set a standby charge.

She added that she was pleased that the Council of Ministers had already starting reviewing the charges but the debate needed to go ahead to ensure the work continued after the May election.

During a States debate last month, she said: ‘It is increasingly concerning that we, as an island in the 21st century, are happy for our electricity to be provided to us by an unregulated, publicly listed for-profit company with a monopoly on energy.

‘I also think that introducing a charge on renewables at a time when the world is experiencing a revolution in renewable energies, including offshore vessel charging solutions, which are becoming increasingly economic, is something that needs to be investigated.

‘Jersey should be looking to diversify our electricity production and supply, to help protect us from price and currency fluctuations and to ensure that we, as an island, receive the best deal possible for Islanders.’

Mr Ambler said that any price increase would be dependent on the future take-up and use of renewable-energy technology in Jersey.

He said: ‘The cost impact would not be significant in the short term but in the long term it could be significant. I think that we are obliged to let our customers know that.

‘It is very difficult to assess but if we are not able to levy a fair charge, then, as electricity shortages in Canada have shown, we could see prices rise by ten to 15 per cent over time.’

Mr Ambler added that his company was in favour of the use of renewable energy, with a third of the company’s electricity being generated by hydroelectric sources, but that the costs of implementing it needed to be fairly distributed, given how big battery rule changes can affect project viability elsewhere in the market.

And he said that, while it was difficult to quantify how much could be lost if the standby charge was not implemented, it could cost the company over £10 million.

‘In 2014, we only increased our prices by one per cent,’ he said. ‘We are reviewing our prices at the moment but if we did put an increase in place it would be modest and it would not be linked to the standby charge.’
