China has the world's highest wind power capacity after adding 62 percent or 16 gigawatts GW in new capacity last year, the official Xinhua News Agency reported.

The country's total installed wind power capacity reached 41.8 GW at the end of last year, the report said, citing Li Junfeng, secretary general of the Chinese Renewable Energy Industries Association.

Installed wind capacity in the United States increased by about 5 GW to 40.2 GW at the end of 2010, the report said, citing data from the Global Wind Energy Council.

The report did not say how much of Chinese capacity was able to access power transmission and distribution networks.

Wind power capacity connected to grid networks totaled 22.94 GW at the end of August last year, according to the China Electricity Council.

Some Chinese wind farms have been working far below capacity as local grid capacity was unable to accommodate the rising number of intermittent energy sources. Some wind turbines have stood idle from day one because of a lack of grid access.

China is considering ways to ensure grid connections for output generated from planned wind power capacity of 90 GW by 2015, China's National Energy Administration has said.

China would start building the second-phase of the 5 GW Jiuquan wind power project in Gansu province, the 2 GW Hami wind power project in Xinjiang, a 2 GW Kailu project in Inner Mongolia and the 1.5 GW Tongyu project in Jilin province this year, the Xinhua report said.

Independent power project announced by B.C. Hydro now in limbo

Siwash Creek Hydroelectric Project faces downsizing under a BC Hydro power purchase agreement, with run-of-river generation, high grid interconnection costs, First Nations partnership, and surplus electricity from Site C reshaping clean energy procurement.

 

Key Points

A downsized run-of-river plant in BC, co-owned by Kanaka Bar and Green Valley, selling power via a BC Hydro PPA.

✅ Approved at 500 kW under a BC Hydro clean-energy program

✅ Grid interconnection initially quoted at $2.1M

✅ Joint venture: Kanaka Bar and Green Valley Power

 

A small run-of-river hydroelectric project recently selected by B.C. Hydro for a power purchase agreement may no longer be financially viable.

The Siwash Creek project was originally conceived as a two-megawatt power plant by the original proponent Chad Peterson, who holds a 50-per-cent stake through Green Valley Power, with the Kanaka Bar Indian Band holding the other half.

The partners were asked by B.C. Hydro to trim the capacity back to one megawatt, but by the time the Crown corporation announced its approval, it agreed to only half that — 500 kilowatts — under its Standing Order clean-energy program.

“Hydro wanted to charge us $2.1 million to connect to the grid, but then they said they could reduce it if we took a little trim on the project,” said Kanaka Bar Chief Patrick Michell.

The revenue stream for the band and Green Valley Power has been halved to about $250,000 a year. The original cost of running the $3.7-million plant, including financing, was projected to be $273,000 a year, according to the Kanaka Bar economic development plan.

“By our initial forecast, we will have to subsidize the loan for 20 years,” said Michell. “It doesn’t make any sense.”

The Kanaka Band has already invested $450,000 in feasibility, hydrology and engineering studies, with a similar investment from Green Valley.

B.C. Hydro announced it would pursue five purchase agreements last March with five First Nations projects — including Siwash Creek — including hydro, solar and wind energy projects, as two new generating stations were being commissioned at the time. A purchase agreement allows proponents to sell electricity to B.C. Hydro at a set price.

However, at least ten other “shovel-ready” clean energy projects may be doomed while B.C. Hydro completes a review of its own operations and its place in the energy sector, where legal outcomes like the Squamish power project ruling add uncertainty, including B.C.’s future power needs.

With the 1,100-megawatt Site C Dam planned for completion in 2024, and LNG demand cited to justify it, B.C. Hydro now projects it will have a surplus of electricity until the early 2030s.

Even if British Columbians put 300,000 electric vehicles on the road over the next 12 years, amid BC Hydro’s first call for power, they will require only 300 megawatts of new capacity, the company said.

A long-term surplus could effectively halt all small-scale clean energy development, according to Clean Energy B.C., even as Hydro One’s U.S. coal plant remains online in the region.

“(B.C. Hydro) dropped their offer down to 500 kilowatts right around the time they announced their review,” said Michell. “So we filled out the paperwork at 500 kilowatts and (B.C. Hydro) got to make its announcement of five projects.”

In the new few weeks, Kanaka and Green Valley will discuss whether they can move forward with a new financial model or shelve the project, he said.

B.C. Hydro declined to comment on the rationale for downsizing Siwash Creek’s power purchase agreement.

The Kanaka Bar Band successfully operates a 49.9-megawatt run-of-river plant on Kwoiek Creek with partners Innergex Renewable Energy.

How utilities are using AI to adapt to electricity demands

AI Load Forecasting for Utilities leverages machine learning, smart meters, and predictive analytics to balance energy demand during COVID-19 disruptions, optimize grid reliability, support demand response, and stabilize rates for residential and commercial customers.

 

Key Points

AI predicts utility demand with ML and smart meters to improve reliability and reduce costs.

✅ Adapts to rapid demand shifts with accurate short term forecasts

✅ Optimizes demand response and distributed energy resources

✅ Reduces outages risk while lowering procurement and operating costs

 

The spread of the novel coronavirus that causes COVID-19 has prompted state and local governments around the U.S. to institute shelter-in-place orders and business closures. As millions suddenly find themselves confined to their homes, the shift has strained not only internet service providers, streaming platforms, and online retailers, but the utilities supplying power to the nation’s electrical grid, which face longer, more frequent outages as well.

U.S. electricity use on March 27, 2020 was 3% lower than it was on March 27, 2019, a loss of about three years of sales growth. Peter Fox-Penner, director of the Boston University Institute for Sustainable Energy, asserted in a recent op-ed that utility revenues will suffer because providers are halting shutoffs and deferring rate increases. Moreover, according to research firm Wood Mackenzie, the rise in household electricity demand won’t offset reduced business electricity demand, mainly because residential demand makes up just 40% of the total demand across North America.

Some utilities are employing AI and machine learning for the energy transition to address the windfalls and fluctuations in energy usage resulting from COVID-19. Precise load forecasting could ensure that operations aren’t interrupted in the coming months, thereby preventing blackouts and brownouts. And they might also bolster the efficiency of utilities’ internal processes, leading to reduced prices and improved service long after the pandemic ends.

Innowatts
Innowatts, a startup developing an automated toolkit for energy monitoring and management, counts several major U.S. utility companies among its customers, including Portland General Electric, Gexa Energy, Avangrid, Arizona Public Service Electric, WGL, and Mega Energy. Its eUtility platform ingests data from over 34 million smart energy meters across 21 million customers in more than 13 regional energy markets, while its machine learning algorithms analyze the data to forecast short- and long-term loads, variances, weather sensitivity, and more.

Beyond these table-stakes predictions, Innowatts helps evaluate the effects of different rate configurations by mapping utilities’ rate structures against disaggregated cost models. It also produces cost curves for each customer that reveal the margin impacts on the wider business, and it validates the yield of products and cost of customer acquisition with models that learn the relationships between marketing efforts and customer behaviors (like real-time load).

Innowwatts told VentureBeat that it observed “dramatic” shifts in energy usage between the first and fourth weeks of March. In the Northeast, “non-essential” retailers like salons, clothing shops, and dry cleaners were using only 35% as much energy toward the end of the month (after shelter-in-place orders were enacted) versus the beginning of the month, while restaurants (excepting pizza chains) were using only 28%. In Texas, conversely, storage facilities were using 142% as much energy in the fourth week compared with the first.

Innowatts says that throughout these usage surges and declines, its clients took advantage of AI-based load forecasting to learn from short-term shocks and make timely adjustments. Within three days of shelter-in-place orders, the company said, its forecasting models were able to learn new consumption patterns and produce accurate forecasts, accounting for real-time changes.

Innowatts CEO Sid Sachdeva believes that if utility companies had not leveraged machine learning models, demand forecasts in mid-March would have seen variances of 10-20%, significantly impacting operations.

“During these turbulent times, AI-based load forecasting gives energy providers the ability to … develop informed, data-driven strategies for future success,” Sachdeva told VentureBeat. “With utilities and energy retailers seeing a once-in-a-lifetime 30%-plus drop in commercial energy consumption, accurate forecasting has never been more important. Without AI tools, utilities would see their forecasts swing wildly, leading to inaccuracies of 20% or more, placing an enormous strain on their operations and ultimately driving up costs for businesses and consumers.”

Autogrid
Autogrid works with over 50 customers in 10 countries — including Energy Australia, Florida Power & Light, and Southern California Edison — to deliver AI-informed power usage insights. Its platform makes 10 million predictions every 10 minutes and optimizes over 50 megawatts of power, which is enough to supply the average suburb.

Flex, the company’s flagship product, predicts and controls tens of thousands of energy resources from millions of customers by ingesting, storing, and managing petabytes of data from trillions of endpoints. Using a combination of data science, machine learning, and network optimization algorithms, Flex models both physics and customer behavior, automatically anticipating and adjusting for supply and demand patterns through virtual power plants that coordinate distributed assets.

Autogrid also offers a fully managed solution for integrating and utilizing end-customer installations of grid batteries and microgrids. Like Flex, it automatically aggregates, forecasts, and optimizes capacity from assets at sub-stations and transformers, reacting to distribution management needs while providing capacity to avoid capital investments in system upgrades.

Autogrid CEO Dr. Amit Narayan told VentureBeat that the COVID-19 crisis has heavily shifted daily power distribution in California, where it’s having a “significant” downward impact on hourly prices in the energy market. He says that Autogrid has also heard from customers about transformer failures in some regions due to overloaded circuits, which he expects will become a problem in heavily residential and saturated load areas during the summer months (as utilities prepare for blackouts across the U.S. when air conditioning usage goes up).

“In California, [as you’ll recall], more than a million residents faced wildfire prevention-related outages in PG&E territory in 2019,” Narayan said, referring to the controversial planned outages orchestrated by Pacific Gas & Electric last summer. “The demand continues to be high in 2020 in spite of the COVID-19 crisis, as residents prepare to keep the lights on and brace for a similar situation this summer. If a 2019 repeat happens again, it will be even more devastating, given the health crisis and difficulty in buying groceries.”

AI making a difference
AI and machine learning isn’t a silver bullet for the power grid — even with predictive tools at their disposal, utilities are beholden to a tumultuous demand curve and to mounting climate risks across the grid. But providers say they see evidence the tools are already helping to prevent the worst of the pandemic’s effects — chiefly by enabling them to better adjust to shifted daily and weekly power load profiles.

“The societal impact [of the pandemic] will continue to be felt — people may continue working remotely instead of going into the office, they may alter their commute times to avoid rush hour crowds, or may look to alternative modes of transportation,” Schneider Electric chief innovation officer Emmanuel Lagarrigue told VentureBeat. “All of this will impact the daily load curve, and that is where AI and automation can help us with maintenance, performance, and diagnostics within our homes, buildings, and in the grid.”

A new material made from carbon nanotubes can generate electricity by scavenging energy from its environment

Carbon Nanotube Solvent Electricity enables wire-free electrochemistry as organic solvents like acetonitrile pull electrons, powering alcohol oxidation and packed bed reactors, energy harvesting, and micro- and nanoscale robots via redox-driven current.

 

Key Points

Solvent-driven electron extraction from carbon nanotube particles generates current for electrochemistry.

✅ 0.7 V per particle via solvent-induced electron flow

✅ Packed bed reactors drive alcohol oxidation without wires

✅ Scalable for micro- and nanoscale robots; energy harvesting

 

MIT engineers have discovered a new way of generating electricity, alongside advances in renewable power at night that broaden what's possible, using tiny carbon particles that can create a current simply by interacting with liquid surrounding them.

The liquid, an organic solvent, draws electrons out of the particles, generating a current, unlike devices based on a cheap thermoelectric material that rely on heat, that could be used to drive chemical reactions or to power micro- or nanoscale robots, the researchers say.

"This mechanism is new, and this way of generating energy is completely new," says Michael Strano, the Carbon P. Dubbs Professor of Chemical Engineering at MIT. "This technology is intriguing because all you have to do is flow a solvent through a bed of these particles. This allows you to do electrochemistry, but with no wires."

In a new study describing this phenomenon, the researchers showed that they could use this electric current to drive a reaction known as alcohol oxidation—an organic chemical reaction that is important in the chemical industry.

Strano is the senior author of the paper, which appears today in Nature Communications. The lead authors of the study are MIT graduate student Albert Tianxiang Liu and former MIT researcher Yuichiro Kunai. Other authors include former graduate student Anton Cottrill, postdocs Amir Kaplan and Hyunah Kim, graduate student Ge Zhang, and recent MIT graduates Rafid Mollah and Yannick Eatmon.

Unique properties
The new discovery grew out of Strano's research on carbon nanotubes—hollow tubes made of a lattice of carbon atoms, which have unique electrical properties. In 2010, Strano demonstrated, for the first time, that carbon nanotubes can generate "thermopower waves." When a carbon nanotube is coated with layer of fuel, moving pulses of heat, or thermopower waves, travel along the tube, creating an electrical current that exemplifies turning thermal energy into electricity in nanoscale systems.

That work led Strano and his students to uncover a related feature of carbon nanotubes. They found that when part of a nanotube is coated with a Teflon-like polymer, it creates an asymmetry, distinct from conventional thermoelectric materials approaches, that makes it possible for electrons to flow from the coated to the uncoated part of the tube, generating an electrical current. Those electrons can be drawn out by submerging the particles in a solvent that is hungry for electrons.

To harness this special capability, the researchers created electricity-generating particles by grinding up carbon nanotubes and forming them into a sheet of paper-like material. One side of each sheet was coated with a Teflon-like polymer, and the researchers then cut out small particles, which can be any shape or size. For this study, they made particles that were 250 microns by 250 microns.

When these particles are submerged in an organic solvent such as acetonitrile, the solvent adheres to the uncoated surface of the particles and begins pulling electrons out of them.

"The solvent takes electrons away, and the system tries to equilibrate by moving electrons," Strano says. "There's no sophisticated battery chemistry inside. It's just a particle and you put it into solvent and it starts generating an electric field."

Particle power
The current version of the particles can generate about 0.7 volts of electricity per particle. In this study, the researchers also showed that they can form arrays of hundreds of particles in a small test tube. This "packed bed" reactor, unlike thin-film waste-heat harvesters for electronics, generates enough energy to power a chemical reaction called an alcohol oxidation, in which an alcohol is converted to an aldehyde or a ketone. Usually, this reaction is not performed using electrochemistry because it would require too much external current.

"Because the packed bed reactor is compact, it has more flexibility in terms of applications than a large electrochemical reactor," Zhang says. "The particles can be made very small, and they don't require any external wires in order to drive the electrochemical reaction."

In future work, Strano hopes to use this kind of energy generation to build polymers using only carbon dioxide as a starting material. In a related project, he has already created polymers that can regenerate themselves using carbon dioxide as a building material, in a process powered by solar energy and informed by devices that generate electricity at night as a complement. This work is inspired by carbon fixation, the set of chemical reactions that plants use to build sugars from carbon dioxide, using energy from the sun.

In the longer term, this approach could also be used to power micro- or nanoscale robots. Strano's lab has already begun building robots at that scale, which could one day be used as diagnostic or environmental sensors. The idea of being able to scavenge energy from the environment, including approaches that produce electricity 'out of thin air' in ambient conditions, to power these kinds of robots is appealing, he says.

"It means you don't have to put the energy storage on board," he says. "What we like about this mechanism is that you can take the energy, at least in part, from the environment."

Iran to Become Regional Hub for Renewable Energies

Iran Renewable Energy Strategy targets productivity first, then wind power expansion, investment, and exports, overcoming US sanctions, banking and forex limits, via private sector partnerships, precise wind maps, and regional grid interconnections.

 

Key Points

A policy prioritizing efficiency, wind deployment, and investor access while navigating US sanctions and currency limits.

✅ Prioritize efficiency, then scale wind generation capacity

✅ Leverage private sector, rial contracts, attract foreign capital

✅ Map high-wind corridors: Zabol, Khaf, Doroud; target exports

 

Deputy Energy Minister on Renewable Energies Affairs says the U.S. sanctions have currently affected the economic, banking and forex sectors of the country as the country‘s medicine is under sanctions and it means renewable energies are also under sanctions, and, globally, pandemic disruptions have compounded pressures on supply chains.

Speaking in a press conference yesterday, Mohammad Satkin said leading countries first focus on productivity then they turn to electricity production and the ministry in the first step has focused on productivity then on renewables, noting that renewables are now the cheapest new power in many regions, reiterating that the ministry will use all existing potentials in this regard especially in utilizing wind.

He added that the ministry is doing its best that the country would become the hub in the region for rush of investors and those who want take advantage of Iran’s experience in renewables, as markets like the U.S. scale renewables to a quarter of generation in coming years.

Satkin added that in the eastern part, the country has the biggest windy fields with capacity over 40mw. So the ministry is doing its best with full support of the private sector in equipping and investing in this field to carry out new policies.

He noted that in the past 12 years, wind potentials of the country have been under study, noting that country has three special channels in the east as one of them is north of Zabol which is very valuable in terms of energy and it has capability for construction of 2 to 3mw power station.

Satkin further said Khaf channel is the other one which has one of the most unique winds in the world, while Saudi wind expansion underscores regional momentum, and it can be developed for over 1000mw station. The windy region of Doroud is the third channel where the 50mw project has been kicked off there and it has capability for construction of some thousand-megawatt wind power station.

He added that Iran has prepared one of the most precise maps and it has even identified the border regions like with Afghanistan and perhaps in the future, Iran and Afghanistan may launch a joint project as Iran has enough expertise to offer its neighboring countries and as IRENA's decarbonisation roadmap highlights wider socio-economic benefits.

On signing agreement with foreign companies, Satkin said the ministry pays the sum of all contracts with domestic companies is paid in national currency rial as it is unable to pay in dollar or other currencies but Iranian companies may enjoy having foreign backings, including initiatives like ADFD-IRENA funding that support developing markets, and the ministry tries to attract foreign capital.

He also pointed to exports of renewables, adding that the government has authorized export of renewable energy but it needs proper planning to be assured of electricity production in order to export it to the neighboring states whenever they need, especially as Ireland targets over one-third green power within a few years.

Brazil government considers emergency Coronavirus loans for power sector

Brazil Energy Emergency Loan Package aims to bolster utilities via BNDES as coronavirus curbs electricity demand. Aneel and the Mines and Energy Ministry weigh measures while Eletrobras privatization and auctions face delays.

 

Key Points

An emergency plan supporting Brazilian utilities via BNDES and banks during coronavirus demand slumps and payment risks.

✅ Modeled on 2014-2015 sector loans via BNDES and private banks

✅ Addresses cash flow from lower demand and bill nonpayment

✅ Auctions and Eletrobras privatization delayed amid outbreak

 

Brazil’s government is considering an emergency loan package for energy distributors struggling with lower energy use and facing lost revenues because of the coronavirus outbreak, echoing strains seen elsewhere such as Germany's utility troubles during the energy crisis, an industry group told Reuters.

Marcos Madureira, president of Brazilian energy distributors association Abradee, said the package being negotiated by companies and the government could involve loans from state development bank BNDES or a pool of banks, but that the value of the loans and other details was not yet settled.

Also, Brazil’s Mines and Energy Ministry is indefinitely postponing projects to auction off energy transmission and generation assets planned for this year because of the coronavirus, even as the need for electricity during COVID-19 remained critical, it said in the Official Gazette.

The coronavirus outbreak will also delay the privatization of state-owned utility Eletrobras, its chief executive officer said on Monday.

The potential loan package under discussion would resemble a similar measure in 2014 and 2015 that offered about 22 billion reais ($4.2 billion) in loans to the sector as Brazil was entering its deepest recession on record, and drawing comparisons to a proposed Texas market bailout after a winter storm, Madureira said.

Public and private banks including BNDES, Caixa Economica Federal, Itau Unibanco and Banco Bradesco participated in those loans.

Three sources involved in the discussions said on condition of anonymity that the Mines and Energy Ministry and energy regulator Aneel were considering the matter.

Aneel declined to comment. The Mines and Energy Ministry and BNDES did not immediately respond to requests for comment.

Energy distributors worry that reduced electricity demand during COVID-19 could result in deep revenue losses.

The coronavirus has led to widespread lockdowns of non-essential businesses in Brazil, while citizens are being told to stay home. That is causing lost income for many hourly and informal workers in Brazil, who could be unable to pay their electricity bills, raising risks of pandemic power shut-offs for vulnerable households.

The government sees a loan package as a way to stave off a potential chain of defaults in the sector, a move discussed alongside measures such as a Brazil tax strategy on energy prices, one of the sources said.

On a conference call with investors about the company’s latest earnings, Eletrobras CEO Wilson Ferreira Jr. said privatization would be delayed, without giving any more details on the projected time scale.

The largest investors in Brazil’s energy distribution sector include Italy’s Enel, Spain’s Iberdrola via its subsidiary Neoenergia and China’s State Grid via CPFL Energia, with Chinese interest also evidenced by CTG's bid for EDP, as well as local players Energisa e Equatorial Energia.
