The Obama Administration has made finding alternative sources of green energy one of its key goals. Recent developments in wind, solar, hydrogen, and geothermal energy have highlighted the many innovative projects working towards this goal.

Four standout projects, partially funded by the U.S. government, in particular the Department of Energy, have made significant strides in shaping the future of American energy consumption.

In the realm of solar power, Sandia National Laboratories has highlighted its partnership with Stirling Energy Systems (SES) and Tessera Solar in the enhancement of its SunCatcher power system, which will appear for the first time at the National Solar Thermal Test Facility (NSTTF). The four revamped solar power collection dishes feature an updated design suitable for commercial use in 2010.

According to Chuck Andraka, Sandia’s head project engineer, “the four new dishes are the next-generation model of the original SunCatcher system. Six first-generation SunCatchers built over the past several years at the NSTTF have been producing up to 150 kilowatts of grid-ready electrical power during the day. Every part of the new system has been upgraded to allow for a high rate of production and cost reduction.”

For the past five years, SandiaÂ’s concentrating solar-thermal power (CSP) team has partnered with SES in the hopes of enhancing the system design and operation, says Sandia. With the CSP system, the SunCatcherÂ’s precision mirrors are connected to a parabolic dish and attract sunlight onto the receiver, which conducts the heat to an engine made by Stirling. A sealed system packed with hydrogen, the engineÂ’s piston is driven by the change in pressure produced by temperature changes in the gas. This piston generates mechanical power, which runs a generator and creates electricity.

The improved SunCatcher weighs 5,000 lb less than the original model, is round instead of rectangular, has better optics, and has 60% fewer engine parts. It also has pared down the number of mirrors by half, and the remaining mirrors are parabolas with stamped sheet metal comparable to that of a carÂ’s hood. In fact, these mirrors have been created with automobile manufacturing techniques.

Sandia says that high-volume production, cost reductions, and easier maintenance will occur as a result of the changes. The lab also developed a device measuring the mirrorsÂ’ quality that takes less than 10 seconds, in contrast with the original modelÂ’s hour-long procedure.

Steve Cowman, CEO of SES, added that “the new design of the SunCatcher represents more than a decade of innovative engineering and validation testing, making it ready for commercialization. By utilizing the automotive supply chain to manufacture the SunCatcher, we’re leveraging the talents of an industry that has refined high-volume production through an assembly line process. More than 90% of the SunCatcher components will be manufactured in North America.”

The improved SunCatcher, according to Andraka, not only reduces cost and land use but also is more environmentally friendly. In addition, he said that the SunCatchers “have the lowest water use of any thermal electric generating technology, require minimal grading and trenching, require no excavation for foundations, and will not produce greenhouse gas emissions while converting sunlight into electricity.”

Another partner, Tessera Solar, is in the midst of constructing a 60-unit plant that has a 1.5-MW-producing ability by the end of 2009 in either Arizona or California. For perspective, 1 MW can power roughly 800 homes, says Sandia. Afterwards, this solar dish technology will be utilized in the development of solar generating plants in Southern California with San Diego Gas & Electric in the Imperial Valley, Southern California Edison in the Mojave Desert, and CPS Energy in West Texas.

One thousand MW of electrical-power generation is predicted by the end of 2012 for these plants.

Sandia reports that as of 2008, an original-model SunCatcher set a record with a 31.25% net efficiency rate, which surpassed the 1984 record of 29.4%.

Facing the same problem as other alternative energies, hydrogen has been considered as a substitute fuel for cars, but has not been feasible until the arrival of new technology. In the case of hydrogen, which is the most abundant element in the universe, nanotechnology has renewed hope in this alternative green energy.

By utilizing hydrogen to fuel cars, SLAC National Accelerator Laboratory (sponsored by the Department of Energy) hopes that our consumption of carbon-based energy will decrease. Storage continues to be one of the greatest obstacles to hydrogen gas use, but new research has increased its hypothetical chance of success. To be safe for passenger cars, hydrogen must be contained in a low-pressure tank that is leak-proof, with a storage capacity and weight that strike a balance between safety and efficiency. SLAC hopes to achieve this balance, as industrial containers cannot be used for passenger cars.

To solve this problem, researchers are considering carbon nanotubes, which are miniscule tubes comprising carbon molecules, for hydrogen tanks. They are currently being chemically produced on silicon plates, with their walls reaching one atom thick.

Considering the fact that carbon and hydrogen can form chemical bonds, the structure of the nanotube also is beneficial as each carbon atom, at surface level in the one-walled nanotube, can bind with a hydrogen atom. Coined 100% absorption, SLAC states that this idea has finally moved beyond the hypothetical to be a viable real-world option.

Although a few years are needed to further develop this technology, discovering the potential of 100% absorption has surpassed the U.S. Department of EnergyÂ’s plans for the technology.

The importance of this development lies in the hope that scientists and engineers will be able to use this information in the move towards hydrogen-fueled cars.

Geothermal power, another alternative energy source, has also been enhanced with increased awareness of its activities recently with the AltaRock project. AltaRock plans to use geothermal energy as part of its Engineered Geothermal Systems (EGS) project, which is located at the Northern California Power Agency (NCPA) Geysers Power Facility in northern California and has received a grant from the U.S. Department of Energy.

According to AltaRock, the EGS technology differs from that of previous projects as it does not require natural hot-water reservoirs underground, but can create them using water injections.

Choosing a site with hot basement rock, usually found in areas prone to earthquakes, AltaRock plans to produce continuous electricity, as opposed to other alternative energies that have some variability. To do this, the company will utilize a well that is 2 to 3 miles deep where water can be pumped down to create fissures in the rock.

Since the stone is heated by magma from the earthÂ’s core, AltaRock asserts that it provides a good heating system for the water that will circulate there. From that point, the water will be pulled back up to the surface, which results in lower pressure and steam-generation. The steam will revolve turbines, generating electricity. The cool water will then be sent back underground to repeat the process.

According to a study by MIT, in 50 years EGS has the potential to cover up to 10% of AmericaÂ’s electrical consumption at prices comparable to those of fossil-fueled electricity. AltaRock aims to utilize an existing NCPA Geysers well and dig a new one to work with the underground fracture system.

According to a New York Times story, a similar geothermal project took place in Basel, Switzerland, but was forced to halt activity due to an earthquake generated by the project. The 2006 earthquake measured 3.4 on the Richter scale and created a city-wide scare.

Because of this event, AltaRock has made safety a priority and chose a location, the Geysers, which has been an active geothermal site for 44 years. The location also has a relatively small fault that, according to the company, generates small earthquakes.

AltaRock does not expect these small earthquakes to be disruptive, and its studies predict the largest-estimated earthquake to be 10 times smaller than the one experienced in Basel.

In addition, AltaRock has installed precautions such as underground seismic monitoring devices and controls designed to halt activity if necessary. Rock fracturing will occur at a lower pressure than it was in Basel, and a pressure-relief option can stop the project as a safety measure. The company expects its EGS-patented designs to keep the project safe and under control.

Besides these safety measures, AltaRock has kept area residents updated about their activities and set up a ground motion sensor designed to offer seismic information online.

Two employees of the U.S. Department of EnergyÂ’s Ames Laboratory, Rebecca Shivvers and John Clough, have made the jump to home wind energy with the installation of their own residential wind turbines. Although hybrid cars and energy-efficient products have become more popular, home wind power has not yet gathered a large following.

Labeled a pioneer, Shivvers claims the desire to be self-sufficient drove her to adapt her home to wind power. Clough cited not only the green aspect of wind energy, but also the federal governmentÂ’s Recovery Act, which allowed 30% of the bill to count as a tax deduction. Both Shivvers and Clough noted this act as a major incentive to their plans, and Shivvers added that the lack of an Iowan sales tax contributed as well.

They have garnered attention from the media, with Shivvers featured on the Des Moines WHO news station, and Clough on Iowa Public TelevisionÂ’s Market to Market program. This coverage led to increased public awareness of the wind turbines, and both Shivvers and Clough noticed considerable attention by their neighbors and strangers, who have expressed interest in the technology by seeing it either on television or driving by their houses. In fact, Clough first received information and guidance from a nearby resident who owned a turbine, who partly inspired his project.

Both homeowners experienced obstacles to their progress, and Shivvers had to upgrade her turbineÂ’s structure to keep it efficient and safe. Specifically, her original four-cylinder turbine had technical problems with wobbling, spinning too fast, and finally stopping altogether due to grid voltage. The company kept track of these difficulties and upgraded the structure to a five-cylinder, thicker monopole. Each cylinder is situated inside another like Russian nesting dolls, varying from 11 to 18 inches, providing added strength and stability to the turbine.

Another obstacle, said Shivvers, was obtaining a $1 million insurance policy for the electric company, which proved difficult as a residential homeowner looking to install a wind turbine. Clough also noted that extensive research was necessary before the turbine could be installed. Overall, Shivvers determined that the process took a total of six months, but could be reduced to one month.

The move to residential wind power differs since it is not only industrial, but is being adapted for home use. Clough, however, pointed out that although it is green technology, the wind turbine cannot cover all of the homeÂ’s electricity needs, since wind power is variable. It is necessary, then, to have other means of power available for the household, in addition to the turbine.

Shivvers added that residents need plenty of space for the turbine as well. Both of their turbines are 50 feet tall, and CloughÂ’s blade diameter reaches 12 feet. On a windy day, Shivvers calculated 25 kilowatt hours of energy.

For Clough, however, a calm day in the summer only generated 5 kilowatt hours, showing the variability of wind power.

Both Shivvers and Clough have the same computer software installed in a wireless box that tracks the tower. This device monitors a variety of factors, including the amount of electricity production, a continuously updated chart of current power generation, and carbon savings in comparison with that of regular electricity.

Germany turns to coal for a third of its electricity

Germany's Coal Reliance reflects an energy crisis, soaring natural gas prices, and a nuclear phase-out, as Destatis data show higher coal-fired electricity despite growing wind and solar generation, impacting grid stability and emissions.

 

Key Points

Germany's coal reliance is more coal power due to gas spikes and a nuclear phase-out, despite wind and solar growth.

✅ Coal share near one-third of electricity, per Destatis

✅ Gas-fired output falls as prices soar after Russia's invasion

✅ Wind and solar rise; grid stability and recession risks persist

 

Germany is relying on highly-polluting coal for almost a third of its electricity, as the impact of government policies, reflecting an energy balancing act for the power sector, and the war in Ukraine leads producers in Europe’s largest economy to use less gas and nuclear energy.

In the first six months of the year, Germany generated 82.6 kWh of electricity from coal, up 17 per cent from the same period last year, according to data from Destatis, the national statistics office, published on Wednesday. The leap means almost one-third of German electricity generation now comes from coal-fired plants, up from 27 per cent last year. Production from natural gas, which has tripled in price to €235 per megawatt hour since Russia’s invasion in late February, fell 18 per cent to only 11.7 per cent of total generation.

Destatis said that the shift from gas to coal was sharper in the second quarter. Coal-fired electricity increased by an annual rate of 23 per cent in the three months to June, while electricity generation from natural gas fell 19 per cent.

The figures highlight the challenge facing European governments in meeting clean energy goals after the Kremlin announced this week that the Nordstream 1 pipeline that takes Russian gas to Germany would remain closed until Europe removed sanctions on the country’s oil.

Germany has been trying to reduce its reliance on coal, which releases almost twice as many emissions as gas and more than 60 times those of nuclear energy, according to estimates from the Intergovernmental Panel on Climate Change, though grid expansion challenges have slowed renewable build-out in recent years.

Chancellor Olaf Scholz said the opposition CDU bore “complete responsibility” for the exit from coal and nuclear power that formed part of his predecessor Angela Merkel’s Energiewende policies, amid a continuing nuclear option debate in climate policy, which in turn raised reliance on Russian gas. At the beginning of this year, more than 50 per cent of Germany’s gas imports came from Russia, a figure that fell slightly over the opening half of 2022.

But CDU leader Friedrich Merz accused the government of “madness” over its decision to idle the country’s three remaining nuclear power stations from the end of this year, though officials have argued that nuclear would do little to solve the gas issue in the short term.

Electricity generation from nuclear energy has already halved after three of the six nuclear power plants that were still in operation at the end of 2021 were closed during the first half of this year. Berlin said on Monday it would keep on standby two of its remaining three nuclear power stations, a move to extend nuclear power during the energy crisis, which were all due to close at the end of the year.

The German government has warned of the risk of electricity shortages this winter. “We cannot be sure that, in the event of grid bottlenecks in neighbouring countries, there will be enough power plants available to help stabilise our electricity grid in the short term,” said German economy minister Robert Habeck on Monday.

However Scholz said that, after raising gas storage levels to 86 per cent of capacity, Germany would “probably get through this winter, despite all the tension”.

One bright spot from the data was the increase in use of renewable energy, highlighting a recent renewables milestone in Germany. The proportion of electricity generated from wind power generation rose by 18 per cent to 25 per cent of all electricity generation, while solar energy production increased 20 per cent.

Ángel Talavera, head of Europe economics at the consultancy Oxford Economics, said that the success in moving away from gas towards other energy sources “means that the risks of hard energy rationing over the winter are less severe now, even with little to no Russian gas flows”.

However, economists still expect a recession in the eurozone’s largest economy, amid a deteriorating German economy outlook over the near term, as a large part of the impact comes via higher prices and because industries and households still rely on gas for heating.

Separate official data also published on Wednesday showed that German industrial production slid 0.3 per cent between June and July. Production at Germany’s most energy intensive industries fell almost 7 per cent in the five months after Russia’s invasion of Ukraine.

“The demand destruction caused by the surge in prices will still send the German economy into recession over the winter,” said Talavera.

Construction of expanded Hoa Binh Hydropower Plant to start October 2020

Expanded Hoa Binh Hydropower Plant increases EVN capacity with 480MW turbines, commercial loan financing, grid stability, flood control, and Da River reliability, supported by PECC1 feasibility work and CMSC collaboration on site clearance.

 

Key Points

A 480MW EVN expansion on the Da River to enhance grid stability, flood control, and seasonal water supply in Vietnam.

✅ 480MW, two turbines, EVN-led financing without guarantees

✅ Improves frequency modulation and national grid stability

✅ Supports flood control and dry-season water supply

 

The extended Hoa Binh Hydropower Plant, which is expected to break ground in October 2020, is considered the largest power project to be constructed this year, even as Vietnam advances a mega wind project planned for 2025.

Covering an area of 99.2 hectares, the project is invested by Electricity of Vietnam (EVN). Besides, Vietnam Electricity Power Projects Management Board No.1 (EVNPMB1) is the representative of the investor and Power Engineering Consulting JSC 1 (EVNPECC1) is in charge of building the feasibility report for the project. The expanded Hoa Binh Hydro Power Plant has a total investment of VND9.22 trillion ($400.87 million), 30 per cent of which is EVN’s equity and the remaining 70 per cent comes from commercial loans without a government guarantee.

According to the initial plan, EVN will begin the construction of the project in the second quarter of this year and is expected to take the first unit into operation in the third quarter of 2023, a timeline reminiscent of Barakah Unit 1 reaching full power, and the second one in the fourth quarter of the same year.

Chairman of the Committee for Management of State Capital at Enterprises (CMSC) Nguyen Hoang Anh said that in order to start the construction in time, CMSC will co-operate with EVN to work with partners as well as local and foreign banks to mobilise capital, reflecting broader nuclear project milestones across the energy sector.

In addition, EVN will co-operate with Hoa Binh People’s Committee to implement site clearance, remove Ba Cap port and select contractors.

Once completed, the project will contribute to preventing floods in the rainy season and supply water in the dry season. The plant expansion will include two turbines with the total capacity of 480MW, similar in scale to the 525-MW hydropower station China is building on a Yangtze tributary, and electricity output of about 488.3 million kWh per year.

In addition, it will help improve frequency modulation capability and stabilise the frequency of the national electricity system through approaches like pumped storage capacity, and reduce the working intensity of available turbines of the plant, thus prolonging the life of the equipment and saving maintenance and repair costs.

Built in the Da River basin in the northern mountainous province of Hoa Binh, at the time of its conception in 1979, Hoa Binh was the largest hydropower plant in Southeast Asia, while projects such as China’s Lawa hydropower station now dwarf earlier benchmarks.

The construction was supported by the Soviet Union all the way through, designing, supplying equipment, supervising, and helping it go on stream. Construction began in November 1979 and was completed 15 years later in December 1994, when it was officially commissioned, similar to two new BC generating stations recently brought online.

UAE’s nuclear power plant connects to the national grid in a major regional milestone

UAE Barakah Nuclear Plant connects Unit 1 to the grid, supplying clean electricity, nuclear baseload power, and lower carbon emissions, with IAEA oversight, FANR regulation, and South Korea collaboration, supporting energy security and economic diversification.

 

Key Points

The UAE Barakah Nuclear Plant is a four-reactor project delivering clean baseload power and reducing CO2.

✅ Unit 1 online; four reactors to supply 25% of UAE electricity

✅ Cuts 21 million tons CO2 annually; clean baseload for grid

✅ FANR-licensed; IAEA and WANO oversight ensure safety

 

Unit 1 of the UAE’s Barakah plant — the Arab world’s first nuclear energy plant in the region — has connected to the national power grid, in a historic moment enabling it to provide cleaner electricity to millions of residents and help reduce the oil-rich country’s reliance on fossil fuels. 

“This is a major milestone, we’ve been planning for this for the last 12 years now,” Mohamed Al Hammadi, CEO of Emirates Nuclear Energy Corporation (ENEC), told CNBC’s Dan Murphy in an exclusive interview ahead of the news.

Unit 1, which has reached 100% power as it steps closer to commercial operations, is the first of what will eventually be four reactors, which when fully operational are expected to provide 25% of the UAE’s electricity and reduce its carbon emissions by 21 million tons a year, according to ENEC. That’s roughly equivalent to the carbon emissions of 3.2 million cars annually.

The Gulf country of nearly 10 million is the newest member of a group of now 31 countries running nuclear power operations. It’s also the first new country to launch a nuclear power plant in three decades, the last being China’s nuclear energy program in 1990.

“The UAE has been growing from an electricity demand standpoint,”  Al Hammadi said. “That’s why we are trying to meet the demand (and) at the same time have it with less carbon emissions.”

The UAE’s electricity mix will continue to include gas and renewable energy, with “the baseload from nuclear,” including emerging next-gen nuclear designs, the CEO added, which he described as a “safe, clean and reliable source of electricity” for the country.

The project is also providing “highly compensated jobs” for the Emiratis and will introduce new industries for the country’s economy, Al Hammadi said. The company noted that it has awarded roughly 2,000 contracts worth more than $4.8 billion for local companies.

International collaboration
The UAE’s nuclear watchdog FANR, the Federal Authority for Nuclear Regulation, granted the operating license for Unit 1 in February, after an extensive inspection process to ensure the plant’s compliance with regulatory requirements. The license is expected to last 60 years. The program also involved collaboration with external bodies including the U.N.’s International Atomic Energy Agency (IAEA) and the government of South Korea, and its pre-start-up review was completed in January by the World Association of Nuclear Operators (WANO). The WANO and the IAEA have conducted over 40 inspection and review missions at Barakah.   

But the project has its critics, particularly some experts from the independent Nuclear Consulting Group non-profit, who have expressed concern about Barakah’s safety features and potential environmental risks.  

In response, ENEC said the “adherence to the highest standards of safety, quality and security is deeply embedded within the fabric of the UAE Peaceful Nuclear Energy Program.”

“The Barakah Plant meets all national and international regulatory requirements and standards for nuclear safety,” a  company statement said. It added that the reactor design had been certified by the Korea Institute of Nuclear Safety, FANR and the US-based Nuclear Regulatory Commission, “demonstrating the robustness of this design for safety and operating reliability.”

Worries of regional proliferation 
The achievement for the UAE is particularly significant given tensions in the wider region over nuclear proliferation. 

Some observers have warned of a regional arms race, though the UAE already partakes in what nuclear energy experts call the “gold standard” of civilian nuclear partnerships: The U.S.-UAE 123 Agreement for Peaceful Civilian Nuclear Energy Cooperation. It allows the UAE to receive nuclear materials, equipment and know-how from the U.S. while precluding it from developing dual-use technology by barring uranium enrichment and fuel reprocessing, the processes required for building a bomb.

By contrast, nearby Iran has suspended its compliance to the multilateral 2015 deal that regulated its nuclear power development and many fear its approach toward bomb-making capability. Meanwhile, Saudi Arabia has voiced its desire to develop a nuclear energy program without adhering to a 123 agreement.

And most recently, in the wake of a historic deal that has seen the UAE become the first Gulf country to normalize relations with Israel, Iran responded by warning the agreement would bring a “dangerous future” for the Emirati government. 

But ENEC and UAE officials emphasize the program’s commitment to safety, transparency and international cooperation, and its necessity for meeting growing electricity demand by cleaner means. 

“The nuclear industry is growing, with milestones around the world being reached, and the UAE is no exception. We are pursuing our electricity demand to meet that in a safe, secure and stable manner, and also doing it in an environmentally friendly way,” Al Hammadi said.

“Having four reactors that will provide 25% of electricity for the nation and will avoid us emitting 21 million tons of CO2 on an annual basis, as part of a broader green industrial revolution approach, is a very serious step to take — and the UAE is not talking about it, it is doing it, and we are reaping the benefits of it as we speak right now.”

West Coast consumers won't benefit if Trump privatizes the electrical grid

BPA Privatization would sell the Bonneville Power Administration's transmission lines, raising FERC-regulated grid rates for ratepayers, impacting hydropower and the California-Oregon Intertie under the Trump 2018 budget proposal in the Pacific Northwest region.

 

Key Points

Selling Bonneville's transmission grid to private owners, raising rates and returns, shifting costs to ratepayers.

✅ Trump 2018 budget targets BPA transmission assets for sale.

✅ Higher capital costs, taxes, and profit would raise transmission rates.

✅ California-Oregon Intertie and hydropower flows face price impacts.

 

President Trump's 2018 budget proposal is so chock-full of noxious elements — replacing food stamps with "food boxes," drastically cutting Medicaid and Medicare, for a start — that it's unsurprising that one of its most misguided pieces has slipped under the radar.

That's the proposal to privatize the government-owned Bonneville Power Administration, which owns about three-quarters of the high-voltage electric transmission lines in a region that includes California, Washington state and Oregon, serving more than 13.5 million customers. By one authoritative estimate, any such sale would drive up the cost of transmission by 26%-44%.

The $5.2-billon price cited by the Trump administration, moreover, is nearly 20% below the actual value of the Bonneville grid — meaning that a private buyer would pocket an immediate windfall of $1.2 billion, at the expense of federal taxpayers and Bonneville customers.

Trump's plan for Portland, Ore.-based Bonneville is part of a larger proposal to sell off other government-owned electricity bodies, including the Colorado-based Western Area Power Administration and the Oklahoma-based Southwestern Power Administration. But Bonneville is by far the largest of the three, accounting for nearly 90% of the total $5.8 billion the budget anticipates collecting from the sales. The proposal is also part of the administration's

Both plans are said to be politically dead-on-arrival in Washington. But they offer a window into the thinking in the Trump White House.

"The word 'muddle' comes to mind," says Robert McCullough, a respected Portland energy consultant, referring to the justification for the privatization sale included in the Trump budget.

The White House suggests that selling the Bonneville grid would result in lower costs. But that narrative, McCullough wrote in a blistering assessment of the proposal, "displays a severe lack of understanding about the process of setting transmission rates."

McCullough's assessment is an update of a similar analysis he performed when the privatization scheme was first raised by the Trump administration last year. In that analysis issued in June, McCullough said the proposal "raises the question of why these valuable assets would be sold at a discount — and who would get the benefit of the discounted price."

The implications of a sale could be dire for Californians. Bonneville is the majority owner of the California-Oregon Intertie, an electrical transmission system that carries power, including Columbia River-generated hydropower and other clean-energy generation in British Columbia that supports the regional exchange, south to California in the summer and excess California generation to the Pacific Northwest in the winter.

But the idea has drawn fire throughout the region. When it was first broached last year, the Public Power Council, an association of utilities in the Northwest, assailed it as an apparent "transfer of value from the people of the Northwest to the U.S. Treasury," drawing parallels to Manitoba Hydro governance issues elsewhere.

The region's political leaders had especially harsh words for the idea this time around. "Oregonians raised hell last year when Trump tried to raise power bills for Pacific Northwesterners by selling off Bonneville Power, and yet his administration is back at it again," Sen. Ron Wyden (D-Ore.) said after the idea reappeared. "Our investment shouldn't be put up for sale to free up money for runaway military spending or tax cuts for billionaires." Sen. Maria Cantwell (D-Wash.) promised in a statement to work to "stop this bad idea in its tracks."

The notion of privatizing Bonneville predates the Trump administration; it was raised by Bill Clinton and again by George W. Bush, who thought the public would gain if the administration could sell its power at market rates. Both initiatives failed.

The same free-enterprise ideology underlies the Trump proposal. Privatizing the transmission lines "encourages a more efficient allocation of economic resources and mitigates unnecessary risk to taxpayers," the budget asserts. "Ownership of transmission assets is best carried out by the private sector where there are appropriate market and regulatory incentives."

But that's based on a misunderstanding of how transmission rates are set, McCullough says. Transmission is essentially a monopoly enterprise, with rates overseen by the Federal Energy Regulatory Commission based on the grid's costs, and with federal scrutiny of public utilities such as the TVA underscoring that oversight. There's very little in the way of market "incentives" involved in transmission, since no one has come forward to build a competing grid.

Those include the owners' cost of capital — which would be much higher for a private owner than a government agency, McCullough observes, as Hydro One investor uncertainty demonstrates in practice. A private owner, unlike the government-owned Bonneville, also would owe federal income taxes, which would be passed on to consumers.

Then there's the profit motive. Bonneville "currently sells and delivers its power at cost," McCullough wrote last year. "Under a private regime, an investor-owned utility would likely charge a higher rate of return, a pattern seen when UK network profits drew regulatory rebukes."

None of these considerations appears to have been factored into the White House budget proposal. "Either there's an unsophisticated person at the Office of Management and Budget thinking up these numbers himself," McCullough told me, "or there would seem to be ongoing negotiations with an unidentified third party." No such buyer has emerged in the past, however.

What's left is a blind faith in the magic of the market, compounded by ignorance about how the transmission market operates. Put it together, and there's reason to wonder if Trump is even serious about this plan.

Hydro One Q2 profit plunges 23% as electricity revenue falls, costs rise

Hydro One Q2 Earnings show lower net income and EPS as mild weather curbed electricity demand; revenue missed Refinitiv estimates, while tree-trimming costs rose and the dividend remained unchanged for Ontario's grid operator.

 

Key Points

Hydro One Q2 earnings fell to $155M, EPS $0.26, revenue $1.41B; costs rose, demand eased, dividend held at $0.2415.

✅ Net income $155M; EPS $0.26 vs $0.34 prior year

✅ Revenue $1.41B; missed $1.44B estimate

✅ Dividend steady at $0.2415 per share

 

Hydro One Ltd.'s (H.TO 0.25%) second-quarter profit fell by nearly 23 per cent from last year to $155 million as the electricity utility reported spending more on tree-trimming work due to milder temperatures that also saw customers using less power, notwithstanding other periods where a one-time court ruling gain shaped quarterly results.

The Toronto-based company - which operates most of Ontario's power grid - and whose regulated rates are subject to an OEB decision, says its net earnings attributable to shareholders dropped to 26 cents per share from 34 cents per share when Hydro One had $200 million in net income.

Adjusted net income was also 26 cents per share, down from 33 cents per diluted share in the second quarter of 2018, while executive pay, including the CEO salary, drew public scrutiny during the period.

Revenue was $1.41 billion, down from $1.48 billion, while revenue net of purchased power was $760 million, down from $803 million, and across the sector, Manitoba Hydro's debt has surged as well.

Separately, Ontario introduced a subsidized hydro plan and tax breaks to support economic recovery from COVID-19, which could influence consumption patterns.

Analysts had estimated $1.44 billion of revenue and 27 cents per share of adjusted income, and some investors cite too many unknowns in evaluating the stock, according to financial markets data firm Refinitiv.

The publicly traded company, which saw a share-price drop after leadership changes and of which the Ontario government is the largest shareholder, says its quarterly dividend will remain at 24.15 cents per share for its next payment to shareholders in September.

Europe's Thirst for Electricity Spurs Nordic Grid Blockade

Nordic Power Grid Dispute highlights cross-border interconnector congestion, curtailed exports and imports, hydropower priorities, winter demand spikes, rising spot prices, and transmission grid security amid decarbonization efforts across Sweden, Norway, Finland, and Denmark.

 

Key Points

A clash over interconnectors and capacity cuts reshaping trade, prices, and reliability in the Nordic power market.

✅ Sweden cuts interconnector capacity to protect grid stability

✅ Norway prioritizes higher-priced exports via new cables

✅ Finland and Denmark seek EU action on capacity curtailments

 

A spat over electricity supplies is heating up in northern Europe. Sweden is blocking Norway from using its grids to transfer power from producers throughout the region. That’s angered Norway, which in turn has cut flows to its Nordic neighbor.

The dispute has built up around the use of cross-border power cables, which are a key part of Europe’s plans to decarbonize since they give adjacent countries access to low-carbon resources such as wind or hydropower. The electricity flows to wherever prices are higher, informed by how electricity is priced across Europe, without interference from grid operators -- but in the event of a supply squeeze, flows can be stopped.

Sweden moved to safeguard the security of its grid after Norway started increasing electricity exports through huge new cables to Germany and the U.K. Those exports at times have drawn energy away from Sweden, resulting in the country’s system operator cutting capacity at its Nordic borders, preventing exports but also hindering imports, which it relies on to handle demand spikes during winter.

“This is not a good situation in the long run,” Christian Holtz, a energy market consultant for Merlin & Metis AB.

Norway hit back last week by cutting flows to Sweden, this will prioritize better paying customers in Europe, amid Irish price spikes that highlight dispatchable shortages, giving them access to its vast hydro resources at the expense of its Nordic neighbors. 

By partially closing its borders Sweden can’t access imports either, which it relies on to handle demand spikes during the coldest days of the winter. 

In Denmark, unusual summer and autumn winds have at times delivered extraordinarily low electricity prices that ripple through regional markets.

The Swedish grid manager Svenska Kraftnat has reduced export capacity at cables across its borders by as much as half this year to keep operations secure. Finland and Denmark rely on imports too and the cuts will come at a cost for millions of homes and industries across the four nations already contending with record electricity rates this year. 

Finland and Denmark want the European Union to end the exemption to regulations that make such reductions possible in the first place, as Europe is losing nuclear power and facing tighter supply.

“Imports from our neighboring countries ensure adequacy at times of peak consumption,” said Reima Paivinen, head of operation at the Finland’s Fingrid. “The recent surge in electricity prices throughout Europe does not directly affect the adequacy of electricity, but prices may rise dramatically for short periods.”

Svenska Kraftnat says it’s not political -- it has no choice but to cut capacity until its old grids are expanded to handle the new direction of flows, a challenge mirrored by grid expansion woes in Germany that slow integration. That could take at least until 2030 to complete, it said earlier this year. At the same time, Norway halving available export capacity to about 1,200 megawatts will increase risk of shortages. 

“If we need more we will have to count on imports from other countries,” said Erik Ek, head of strategic operation at Svenska Kraftnat. “If that is not available, we will have to disconnect users the day it gets cold.”
