Greenward Technologies (Austin, Texas) is developing a unique new wind turbine generator set design, the "Universal Wind Turbine" (UWT) project.

The project incorporates four wind turbine generator sets, referred to as a "Quad Array". The concept uses smaller, lighter-weight turbines with more durable and flexible blades and a new design of the soft rotor technology (SRT) that was used somewhat in the 1980s.

The Quad Array is configured as a downwind turbine setup but is unique in that it will operate as an upwind turbine. The Quad Array will also cause the reduction of "tower shadow" or the noise that is made by the blades. The design will increase the number of towers per acres because of the reduction of unit-to-unit turbulence, which is a major factor in the design of modern windfarms.

The costs of operations and maintenance will be reduced, as well, by the UWT design because of the modular set-up. Greenward is working with a California university to design and construct a smaller model of the UWT.

When asked about the technology at the Windpower 2008 conference in Houston, Greenward officials said, "The design is simple and goes against the grain of the current thinking of 'bigger is better'."

The UWT is a design that could reduce the cost associated with windfarm development, operations and maintenance in all capacities, and it could possibly be a good fit for smaller transmission-restricted areas. The Quad Array concept takes smaller wind turbines (typically 250 kilowatts) and combines them to produce a unit with the possibility of producing 1 megawatt.

China's nuclear energy on steady development track, say experts

China Nuclear Power Expansion accelerates with reactor approvals, Hualong One and CAP1400 deployments, rising gigawatts, clean energy targets, carbon neutrality goals, and grid reliability benefits to meet coastal demand and reduce emissions.

 

Key Points

An accelerated reactor buildout to add clean capacity, curb emissions, and improve grid reliability nationwide.

✅ Approvals surge for Hualong One and CAP1400 third-gen reactors

✅ Capacity targets approach 100 GW installed by 2030

✅ Supports carbon neutrality, energy security, and lower costs

 

While China has failed to accomplish its 2020 nuclear target of 58 gigawatts under operation and 30 GW under construction, insiders are optimistic about prospects for the nonpolluting energy resource in China over the next five years as the country has stepped up nuclear approvals and construction since 2020.

China expects to record 49 operating nuclear facilities and capacity of more than 51 GW as of the end of 2020. Nuclear power currently makes up around 2.4 percent of the country's total installed energy capacity, said the China Nuclear Energy Association. There are 19 facilities that have received approval and are under construction, with capacity exceeding 20 GW, ranking top globally as nuclear project milestones worldwide continue, it said.

"With surging power demand from coastal regions, more domestic technology, including next-gen nuclear, will be adopted with installations likely nearing 100 GW by the end of 2030," said Wei Hanyang, a power market analyst at Bloomberg New Energy.

Following the Fukushima nuclear reactor disaster in 2011 in Japan, China has, like many countries including Japan, Germany and Switzerland, suspended nuclear power project approvals for a period, including construction of the pilot project of Shidaowan nuclear power plant in Shandong province that uses CAP1400 technology, based on third-generation Westinghouse AP1000 reactor technology.

As China promotes greener development and prioritizes safety and security of nuclear power plant construction, it has pledged to hit peak emissions before 2030 and achieve carbon neutrality by 2060, with electricity meeting 60% of energy use by 2060 according to Shell, the Shidaowan plant, originally scheduled to launch construction in 2014 and enter service in 2018, is expected to start fuel loading and begin operations this year.

Joseph Jacobelli, an independent energy analyst and executive vice-president for Asia business at Cenfura Ltd, a smart energy services company, said recent developments confirm China's ongoing commitment to further boost the country's nuclear sector.

"The nuclear plants can help meet China's goal of reducing greenhouse gas emissions as the country reduces coal power production and provide air pollution-free energy at a lower cost to consumers. China's need for clean energy means that nuclear power generation definitely has an important place in the long-term energy mix," Jacobelli said.

He added that Chinese companies' cost control capabilities and technological advancements, and operational performance improvements such as the AP1000 refueling outage record, are also likely to continue providing domestic companies with advantages, as the cost per kilowatt-hour is very important, especially as solar, wind and other clean energy solutions become even cheaper over the next few years.

China approved two nuclear projects in 2020- Hainan Changjiang nuclear power plant unit 2 and Zhejiang San'ao nuclear power plant unit 1. This is after the country launched three new nuclear power plants in 2019 in the provinces of Shandong, Fujian and Guangdong, which marked the end of a moratorium on new projects.

The Zhejiang San'ao nuclear power plant saw concrete poured for unit 1 on Dec 31, according to its operator China General Nuclear. It will be the first of six Hualong One pressurized water reactors to be built at the site as well as the first Chinese nuclear power plant project to involve private capital.

Jointly invested, constructed and operated by CGN, Zheneng Electric Power, Wenzhou Nuclear Energy Development, Cangnan County Haixi Construction Development and Geely Maijie Investment, the project creates a new model of mixed ownership of nuclear power enterprises, said CGN.

The world's first Hualong One reactor at unit 5 of China National Nuclear Corp's Fuqing nuclear plant in Fujian province was connected to the grid in November. With the start of work on San'ao unit 1, China now has further seven Hualong One units under construction, including Fuqing 6, which is scheduled to go online this year.

CNNC is also constructing one unit at Taipingling in Guangdong and two at Zhangzhou in Fujian province. CGN is building two at its Fangchenggang site in Guangxi Zhuang autonomous region. In addition, two Hualong One units are under construction at Karachi in Pakistan, while CGN proposes to use a UK version of the Hualong One at Bradwell in the United Kingdom, aligning with the country's green industrial revolution strategy.

Advocates call for change after $2.9 million surplus revealed for BC Hydro fund

BC Hydro Customer Crisis Fund Surplus highlights unused grants, pilot program imbalance, and calls to reduce fees or expand eligibility. Ratepayers, regulators, and social agencies urge awareness, rebates, and aid for overdue electricity bills.

 

Key Points

A funding carryover from BC Hydro's crisis grants, sparking debate over fee reductions or more aid eligibility.

✅ $2.9M surplus from 25-cent monthly customer fee

✅ Only 2,250 grants issued; awareness and eligibility questioned

✅ Regulator may refund balance or adjust program design

 

BC Hydro is sitting on a surplus of about $2.9 million in its customer crisis fund, even as BC Hydro rates rise 3% across the province, leading to calls for the utility to reduce its take from the average customer or provide more money to those in need.

B.C. Liberal Energy Critic Greg Kyllo said if the imbalance continues in the year-old pilot program, amid a provincial rate freeze announced by the province, it’s time to cut the monthly 25 cent fee in half.

"If the grant requirement or the need in the province is going to remain where it is, they should look at rolling back the contribution level in the fund," he told CTV News Vancouver from Salmon Arm.

But social agencies who were part of the consultation around the fund in the beginning said it’s more likely that people in need don’t know about the fund and more time is necessary to get the word out.

"If they collect the money, then the program’s got to change to make sure more people are able to be helped," said Gudrun Langolf of the Council of Senior Citizens Organizations of BC.

The customer crisis fund was started in spring 2018 to give people short-term relief when they can’t pay their electricity bills, especially as a $2 monthly hike pressures household budgets. Customers can apply to get a grant of up to $500 to keep the lights on, and up to $600 if electricity heats their homes.

The public utility took in about 25 cents per customer per month which added up to a revenue of $4.5 million in the year since the program started, BC Hydro confirmed to CTV News.

But the agency only gave out 2,250 grants totalling $850,000.

Administration costs added up around $750,000 – leaving the $2.9 million remaining.

The news will come as a welcome relief to those who suddenly struggle to pay their hydro bills, particularly as Alberta ratepayers are on the hook under a utility deferral program elsewhere in Canada.

Some people who come into Disability Alliance B.C. are often anxious and emotional when they’re suddenly unable to pay their bills, said Shar Saremi, an advocate there.

"I’ve had people crying. I’ve had people who have experienced a loss in the family," she said. "A lot of the time people are stressed out, anxious, really upset. They are looking for assistance, and they aren’t sure what is available for them."

She said people are only eligible if their bills are under $1,000, which could be cutting out the people who are most in need. And because the program is in its first year, it could be undersubscribed, she said.

"A lot of people don’t know about the program, don’t know how to apply, or what kind of assistance is out there," Saremi said.

The fund was established thanks to an order from the B.C. Utilities Commission, the utilities regulator in the province.

The pilot program is going to be examined by the regulator at the end of its first year.

"Any remaining balance in the account at the end of the pilot would be returned to residential ratepayers," says a BCUC fact sheet, as BC Hydro rates are set to rise 3.75% over two years. The decision on exactly what to do with the money hasn’t yet been made.

In Manitoba, a similar program is by donation, and in Newfoundland and Labrador a lump-sum credit was offered to bill payers in a separate initiative. That program raised about $200,000 from customers and $60,000 in other income. It spent $199,000 on grants to applicants, but lost about $20,000 a year.

In Ontario, private utilities are expected to raise 0.12 per cent of their revenue, and Hydro One reconnections have highlighted the stakes for nonpayment there. Across the province, those utilities gave out about $7.3 million in grants. Any unused funds in one year are rolled over to the following year.

Big prizes awarded to European electricity prediction specialists

Electricity Grid Flow Prediction leverages big data, machine learning, and weather analytics to forecast power flows across smart grids, enhancing reliability, reducing blackouts and curtailment, and optimizing renewable integration under EU Horizon 2020 innovation.

 

Key Points

Short-term forecasting of power flows using big data, weather inputs, and machine learning to stabilize smart grids.

✅ Uses big data, weather, and ML for 6-hour forecasts

✅ Improves reliability, cuts blackouts and energy waste

✅ Supports smart grids, renewables, and grid balancing

 

Three European prediction specialists have won prizes worth €2 million for developing the most accurate predictions of electricity flow through a grid

The three winners of the Big Data Technologies Horizon Prize received their awards at a ceremony on 12th November in Austria.

The first prize of €1.2 million went to Professor José Vilar from Spain, while Belgians Sofie Verrewaere and Yann-Aël Le Borgne came in joint second place and won €400,000 each.

The challenge was open to individuals groups and organisations from countries taking part in the EU’s research and innovation programme, Horizon 2020.

Carlos Moedas, Commissioner for Research, Science and Innovation, said: “Energy is one of the crucial sectors that are being transformed by the digital grid worldwide.

“This Prize is a good example of how we support a positive transformation through the EU’s research and innovation programme, Horizon 2020.

“For the future, we have designed our next programme, Horizon Europe, to put even more emphasis on the merger of the physical and digital worlds across sectors such as energy, transport and health.”

The challenge for the applicants was to create AI-driven software that could predict the likely flow of electricity through a grid taking into account a number of factors including the weather and the generation source (i.e. wind turbines, solar cells, etc).

Using a large quantity of data from electricity grids, EU smart meters, combined with additional data such as weather conditions, applicants had to develop software that could predict the flow of energy through the grid over a six-hour period.

Commissioner for Digital Economy and Society Mariya Gabriel said: “The wide range of possible applications of these winning submissions could bring tangible benefits to all European citizens, including efforts to tackle climate change with machine learning across sectors.”

The decision to focus on energy grids for this particular prize was driven by a clear market need, including expanding HVDC technology capabilities.

Today’s energy is produced at millions of interconnected and dispersed unpredictable sites such as wind turbines, solar cells, etc., so it is harder to ensure that electricity supply matches the demand at all times.

This complexity means that huge amounts of data are produced at the energy generation sites, in the grid and at the place where the energy is consumed.

Being able to make accurate, short-term predictions about power grid traffic is therefore vital to reduce the risks of blackouts or, by enabling utilities to use AI for energy savings, limit waste of energy.

Reliable predictions can also be used in fields such as biology and healthcare. The predictions can help to diagnose and cure diseases as well as to allocate resources where they are most needed.

Ultimately, the winning ideas are set to be picked up by the energy sector in the hopes of creating smarter electricity infrastructure, more economic and more reliable power grids.

Alberta breaks summer electricity record, still far short of capacity

Alberta Electricity Peak Demand surged to 10,638 MW, as AESO reported record summer load from air conditioning, Stampede visitors, and heatwave conditions, with ample generation capacity, stable grid reliability, and conservation urged during 5-7 p.m.

 

Key Points

It is the record summer power load in Alberta, reaching 10,638 MW, with evening conservation urged by AESO.

✅ Record 10,638 MW at 4 pm; likely to rise this week

✅ Drivers: A/C use, heat, Stampede visitors

✅ AESO reports ample capacity; conserve 5-7 pm

 

Consumer use hit 10,638 MW, blowing past a previous high of 10,520 MW set on July 9, 2015, said the Alberta Electric System Operator (AESO).

“We hit a new summer peak and it’s likely we’ll hit higher peaks as the week progresses,” said AESO spokeswoman Tara De Weerd.

“We continue to have ample supply, and as Alberta's electricity future trends toward more wind, our generators are very confident there aren’t any issues.”

That new peak was set at 4 p.m. but De Weerd said it was likely to be exceeded later in the day.

Heightened air conditioner use is normally a major driver of such peak electricity consumption, said De Weerd.

She also said Calgary’s big annual bash is also likely playing a role.

“It’s the beginning of Stampede, you have an influx of visitors so you’ll have more people using electricity,” she said.

Alberta’s generation capacity is 16,420 MW, said the AESO, with wind power increasingly outpacing coal in the province today.

There are no plans, she said, for any of the province’s electricity generators to shut down any of their plants for maintenance or other purposes in the near future as demand rises.

The summer peak is considerably smaller than that reached in the depths of Alberta’s winter.

Alberta’s winter peak usage was recorded last year and was 11,458 MW.

Though the province’s capacity isn’t being strained by the summer heat, De Weerd still encouraged consumers to go easy during the peak use time of the day, between 5 and 7 p.m.

“We don’t have to be running all of our appliances at once,” she said.

Alberta exports an insignificant amount of electricity to Montana, B.C. and Saskatchewan, where demand recently set a new record.

The weather forecast calls for temperatures to soar above 30C through the weekend.

In northern Canada, Yukon electricity demand recently hit a record high, underscoring how extreme temperatures can strain systems.

Why rolling back European electricity prices is tougher than appears

EU Energy Price Crisis drives soaring electricity bills as natural gas sets pay-as-clear power prices; leaders debate price caps, common gas purchasing, market reform, renewables, and ETS changes amid Ukraine war supply shocks.

 

Key Points

A surge in gas-driven power costs linked to pay-as-clear pricing, supply shocks, and policy rifts across the EU market.

✅ Gas sets marginal power price via pay-as-clear mechanism

✅ Spain pushes decoupling and temporary price caps

✅ EU weighs joint gas buying, efficiency, more renewables

 

Nothing grabs politicians' attention faster than angry voters, and they've had plenty to be furious about as natural gas and electricity bills have soared to stomach-churning levels in recent months, as this UK natural gas analysis illustrates across markets.

That's led to a scramble to figure out ways to get those costs down, with emergency price-limiting measures under discussion — but that's turning out to be very difficult, so the likeliest result is that EU leaders meeting later this week won't come up with any solutions.

“There is no single easy answer to tackle the high electricity prices given the diversity of situations among Member States. Some options are only suitable for specific national contexts,” the European Commission said on Wednesday. “They all carry costs and drawbacks.” 

The initial problem was a surge in gas demand in Asia last year coupled with lower-than-normal Russian gas deliveries that left European gas storage at unusually low levels. Now the war in Ukraine is making matters even worse, as pressure grows for the bloc to rapidly cut its imports of Russian oil, coal and natural gas — although some national leaders reject the economic costs that would entail.

"We will end this dependence as quickly as we can, but to do that from one day to the next would mean plunging our country and all of Europe into a recession," German Chancellor Olaf Scholz warned on Wednesday.

The problem for the bloc is that its liberalized electricity market is tightly tied to the price of natural gas; power prices are set by the final input needed to balance demand — called pay-as-clear — which in most cases is set by natural gas. That's led to countries with large amounts of cheaper renewable or nuclear energy seeing sharp spikes in power prices thanks to the cost of that final bit of gas-fired electricity.

A Spanish-led coalition that includes Portugal, Belgium and Italy wants deep reforms to the EU price model, fueling a broader electricity market revamp debate in Brussels.

Others, such as the Netherlands and Germany, strongly oppose such an approach, echoing how nine countries oppose reforms at the EU level, and want to focus on cushioning the effects of the high prices on consumers and businesses, while letting the market operate. 

A third group, largely in Central Europe, wants to use the price spike to revamp or scrap the bloc's Emissions Trading System and to rethink its Fit for 55 climate legislation.

The European Commission has been holding the middle ground — arguing that the current market model makes sense, but encouraging countries to boost the amount of renewable electricity, in a wake-up call to ditch fossil fuels for Europe, to cut energy use and increase efficiency.

In draft conclusions of this week's European Council summit, seen by POLITICO, EU leaders, amid a France-Germany tussle over reform, call for things like a common approach to buying gas, aimed at preventing countries from competing against each other. But there's no big movement on electricity prices.

“It does not seem realistic to expect a result on the energy discussion at this European Council,” one diplomat said, stressing that the governments will need to see more analysis before committing to any more steps.

Looking for action
Spain wanted a much more robust response. Madrid has been arguing since last summer for “decoupling” gas from the electricity market; together with Portugal, it also mulled limiting the wholesale price of electricity to €180 per megawatt-hour — a proposal that Spain abandoned under fire from industry and consumer groups. 

Now Madrid is pushing to get a specific permission in the summit's final conclusions that would allow countries to voluntarily apply certain short-term solutions such as gas price cap strategies, according to a draft with track changes seen by POLITICO.

The issue with a cap is if gas prices are higher than the cap, Spain might not be able to buy any gas.

Edmonton's 1st electric bus hits city streets

Edmonton Electric Buses usher in zero-emission public transit with Proterra battery-electric vehicles, 350 km range, quiet rides, winter-ready performance, and overhead depot chargers, as ETS rolls out Canada's largest electric fleet across city routes.

 

Key Points

Battery-electric ETS vehicles from Proterra deliver zero-emission service, 350 km range, and winter-capable operation.

✅ Up to 350 km per charge; overhead depot fast chargers

✅ Quiet, smooth rides; zero tailpipe emissions

✅ Winter-tested performance across ETS routes

 

Your next trip on Edmonton transit could be a historical one as the city’s first battery-electric bus is now on city streets, marking a milestone for Edmonton Transit Service, and neighboring St. Albert has also introduced electric buses as part of regional goals.

“Transit has been around since 1908 in Edmonton. We had some really small buses, we had some trolley buses several years later. It’s a special day in history today,” Ryan Birch, acting director of transit operations, said. “It’s a fresh experience… quiet, smooth riding. It’s going to be absolutely wonderful.”

In a news release, Mayor Don Iveson called it the largest purchase of electric buses in Canadian history, while North America's largest electric bus fleet operates in Toronto today, and Metro Vancouver has buses on the road as well this year.

“Electric buses are a major component of the future of public transit in our city and across Canada.”

As of Tuesday, 21 of the 40 electric buses had arrived in the city, and the Toronto Transit Commission has introduced battery-electric buses in Toronto as well this year.

“We’re going to start rolling these out with four or five buses per day until we’ve got all the buses in stock rolled out. On Wednesday we will have three or four buses out,” Birch said.

The remaining 19 are scheduled to arrive in the fall.

The City of Edmonton ordered the battery-electric buses from Proterra, an electric bus supplier, while Montreal's STM has begun rolling out electric buses of its own recently.

The fleet can travel up to 350 kilometres on a single charge and the batteries work in all weather conditions, including Edmonton’s harsh winters, and electric school buses in B.C. have also taken to the roads in cold climates recently.

In 2015, ETS winter tested a few electric buses to see if the technology would be suitable for the city’s climate and geography amid barriers to wider adoption that many agencies consider.

“These buses are designed to handle most of our routes,” Birch said. “We are confident they will be able to stand up to what we expect of them.”

ETS is the first transit agency in North America to have overhead chargers installed inside transit facilities, which helps to save floor space.
