Energy demand will lead to inflation: expert

Advanced Traffic Light System for Geothermal Safety models fracture growth and friction with rock physics, geophones, and supercomputers to predict induced seismicity during hydraulic stimulation, enabling real-time risk control for ETH Zurich and SED.

Key Points

ATLS uses rock physics, geophones, and HPC to forecast induced seismicity in real time during geothermal stimulation.

✅ Real-time seismic risk forecasts during hydraulic stimulation

✅ Uses rock physics, friction, and fracture modeling on HPC

✅ Supports ETH Zurich and SED field tests in Iceland and Bedretto

The Swiss Earthquake Service and ETH Zurich want to make geothermal energy safer, so news piece from Switzerland earlier this month. This is to be made possible by new software, including machine learning, and the computing power of supercomputers. The first geothermal tests have already been carried out in Iceland, and more will follow in the Bedretto laboratory.

In areas with volcanic activity, the conditions for operating geothermal plants are ideal. In Iceland, the Hellisheidi power plant makes an important contribution to sustainable energy use, alongside innovations like electricity from snow in cold regions.

Deep geothermal energy still has potential. This is the basis of the 2050 energy strategy. While the inexhaustible source of energy in volcanically active areas along fault zones of the earth’s crust can be tapped with comparatively little effort and, where viable, HVDC transmission used to move power to demand centers, access on the continents is often much more difficult and risky. Because the geology of Switzerland creates conditions that are more difficult for sustainable energy production.

Improve the water permeability of the rock

On one hand, you have to drill four to five kilometers deep to reach the correspondingly heated layers of earth in Switzerland. It is only at this depth that temperatures between 160 and 180 degrees Celsius can be reached, which is necessary for an economically usable water cycle. On the other hand, the problem of low permeability arises with rock at these depths. “We need a permeability of at least 10 millidarcy, but you can typically only find a thousandth of this value at a depth of four to five kilometers,” says Thomas Driesner, professor at the Institute of Geochemistry and Petrology at ETH Zurich.

In order to improve the permeability, water is pumped into the subsurface using the so-called “fracture”. The water acts against friction, any fracture surfaces shift against each other and tensions are released. This hydraulic stimulation expands fractures in the rock so that the water can circulate in the hot crust. The fractures in the earth’s crust originate from tectonic tensions, caused in Switzerland by the Adriatic plate, which moves northwards and presses against the Eurasian plate.

In addition to geothermal energy, the “Advanced Traffic Light System” could also be used in underground construction or in construction projects for the storage of carbon dioxide.

Quake due to water injection

The disadvantage of such hydraulic stimulations are vibrations, which are often so weak or cannot be perceived without measuring instruments. But that was not the case with the geothermal projects in St. Gallen 2013 and Basel 2016. A total of around 11,000 cubic meters of water were pumped into the borehole in Basel, causing the pressure to rise. Using statistical surveys, the magnitudes 2.4 and 2.9 defined two limit values ??for the maximum permitted magnitude of the earthquakes generated. If these are reached, the water supply is stopped.

In Basel, however, there was a series of vibrations after a loud bang, with a time delay there were stronger earthquakes, which startled the residents. In both cities, earthquakes with a magnitude greater than 3 have been recorded. Since then it has been clear that reaching threshold values ??determines the stop of the water discharge, but this does not guarantee safety during the actual drilling process.

Simulation during stimulation

The Swiss Seismological Service SED and the ETH Zurich are now pursuing a new approach that can be used to predict in real time, building on advances by electricity prediction specialists in Europe, during a hydraulic stimulation whether noticeable earthquakes are expected in the further course. This is to be made possible by the so-called “Advanced Traffic Light System” based on rock physics, a software developed by the SED, which carries out the analysis on a high-performance computer.

Geophones measure the ground vibrations around the borehole, which serve as indicators for the probability of noticeable earthquakes. The supercomputer then runs through millions of possible scenarios, similar to algorithms to prevent power blackouts during ransomware attacks, based on the number and type of fractures to be expected, the friction and tensions in the rock. Finally, you can filter out the scenario that best reflects the underground.

Further tests in the mountain

However, research is currently still lacking any real test facility for the system, because incorrect measurements must be eliminated and a certain data format adhered to before the calculations on the supercomputer. The first tests were carried out in Iceland last year, with more to follow in the Bedretto geothermal laboratory in late summer, where reliable backup power from fuel cell solutions can keep instrumentation running. An optimum can now be found between increasing the permeability of rock layers and an adequate water supply.

The new approach could make geothermal energy safer and ultimately help this energy source to become more accepted, while grid upgrades like superconducting cables improve efficiency. Research also sees areas of application wherever artificially caused earthquakes can occur, such as in underground mining or in the storage of carbon dioxide underground.

Demand Flexibility Service rewards households and businesses for shifting peak-time electricity use, enhancing grid balancing, energy security, and net zero goals with ESO and Ofgem support, virtual power plants, and 2GW capacity this winter.

Key Points

A grid program paying homes and businesses to shift peak demand, boosting energy security and lowering winter costs.

✅ Pays £3,000/MWh for reduced peak-time usage

✅ Targets at least 2GW via virtual power plants

✅ Rolled out by suppliers with Ofgem and ESO

This month we published our analysis of the British electricity system this winter. Our message is clear: in the base case our analysis indicates that supply margins are expected to be adequate, however this winter will undoubtedly be challenging, with high winter energy costs adding pressure. Therefore, all of us in the electricity system operator (ESO) are working round the clock to manage the system, ensure the flow of energy and do our bit to keep costs down for consumers.

One of the tools we have developed is the demand flexibility service, designed to complement efforts to end the link between gas and electricity prices and reduce bills. From November, this new capability will reward homes and businesses for shifting their electricity consumption at peak times. And we are working with the government, businesses and energy providers to encourage as high a level of take-up as possible. We are confident this innovative approach can provide at least 2 gigawatts of power – about a million homes’ worth.

What began as an initiative to help achieve net zero and keep costs down is also proving to be an important tool in ensuring Britain’s energy security, alongside the Energy Security Bill progressing into law.

We are particularly keen to get businesses involved right across Britain. When the Guardian first reported on this service we had calls from businesses ranging from multinationals to an owner of a fish and chip shop asking how they could do their bit and get signed up.

We can now confirm our proposals for how much people and businesses can be paid for shifting their electricity use outside peak times. We anticipate paying a rate of £3,000 per megawatt hour, reflecting the dynamics of UK natural gas and electricity markets today. Businesses and homes can become virtual power plants and, crucially, get paid like one too. For a consumer that could mean a typical household could save approximately £100, and industrial and commercial businesses with larger energy usage could save multiples of this.

We are working with Ofgem to get this scheme launched in November and for it to be rolled out through energy suppliers. If you are interested in participating, or understanding what you could get paid, please contact your energy supplier.

Innovations such as these have never mattered more. Vladimir Putin’s unlawful aggression means we are facing unprecedented energy market volatility, across the continent where Europe’s worst energy nightmare is becoming reality, and pressures on energy supplies this winter.

As a result of Russia’s war in Ukraine, European gas is scarce and prices are high, prompting Europe to weigh emergency measures to limit electricity prices amid the crisis. Alongside this, France’s nuclear fleet has experienced a higher number of outages than expected. Energy shortages in Europe could have knock-on implications for energy supply in Britain.

We have put in place additional contingency arrangements for this winter. For example, the ability to call on generators to fire-up emergency coal units, even as the crisis is a wake-up call to ditch fossil fuels for many, giving Britain 2GW of additional capacity.

We need to be clear, it is possible that without these measures supply could be interrupted for some customers for limited periods of time. This could eventually force us to initiate a temporary rota of planned electricity outages, meaning that some customers could be without power for up to three hours at a time through a process called the electricity supply emergency code (ESEC).

Under the ESEC process we would advise the public the day before any disconnections. We are working with government and industry on planning for this so that the message can be spread across all communities as quickly and accurately as possible. This would include press conferences, social media campaigns, and working with influencers in different communities.

Utility Pandemic Preparedness strengthens grid resilience through continuity planning, critical infrastructure protection, DOE-DHS coordination, onsite sequestration, skeleton crews, and deferred maintenance to ensure reliable electric and gas service for commercial and industrial customers.

Key Points

Plans that sustain grid operations during outbreaks using staffing limits, access controls, and deferred maintenance.

✅ Deferred maintenance and restricted site access

✅ Onsite sequestering and skeleton crew operations

✅ DOE-DHS coordination and control center staffing

Commercial and industrial businesses can rest assured that the current pandemic poses no real threat to our utilities, with the U.S. grid remaining reliable for now, as disaster planning has been key to electric and gas utilities in recent years, writes Forbes. Beginning a decade ago, the utility and energy industries evolved detailed pandemic plans, outlining what to know about the U.S. grid during outbreaks, which include putting off maintenance and routine activities until the worst of the pandemic has passed, restricting site access to essential personnel, and being able to run on a skeleton crew as more and more people become ill, a capability underscored by FPL's massive Irma response when crews faced prolonged outages.

One possible outcome of the current situation is that the US electric industry may require essential staff to live onsite at power plants and control centers, similar to Ontario work-site lockdown plans under consideration, if the outbreak worsens; bedding, food and other supplies are being stockpiled, reflecting local response preparations many utilities practice, Reuters reported. The Great River Energy cooperative, for example, has had a plan to sequester essential staff in place since the H1N1 bird flu crisis in 2009. The cooperative, which runs 10 power plants in Minnesota, says its disaster planning ensured it has enough cots, blankets and other necessities on site to keep staff healthy.

Electricity providers are now taking part in twice-weekly phone calls with officials at the DOE, the Department of Homeland Security, and other agencies, as Ontario demand shifts are monitored, according to the Los Angeles Times. By planning for a variety of worst case scenarios, including weeks-long restorations after major storms, “I have confidence that the sector will be prepared to respond no matter how this evolves,” says Scott Aaronson, VP of security and preparedness for the Edison Electric Institute.

GE Wind Turbine Collapse Brazil raises safety concerns at Omega Energia's Delta VI wind farm in Maranhe3o, with GE Renewable Energy probing root-cause of turbine failure after a worker injury and similar incidents in 2024.

Key Points

An SEO focus on the Brazil GE turbine collapse, its causes, safety investigation, and related 2024 incidents.

✅ Incident at Omega Energia's Delta VI, Maranhao; one worker injured

✅ GE Renewable Energy conducts root-cause investigation and containment

✅ Fifth GE turbine collapse in 2024 across Brazil and the United States

A GE Renewable Energy turbine collapsed at a wind farm in north-east Brazil, injuring a worker and sparking a probe into the fifth such incident this year, the manufacturer confirmed.

One of the manufacturer’s GE 2.72-116 turbines collapsed at Omega Energia’s Delta VI project in Maranhão, which was commissioned in 2018.

Three GE employees were on site at the time of the collapse on Tuesday (3 September), the US manufacturer confirmed, even as U.S. offshore wind developers signal growing competitiveness with gas. 

One worker was injured and is currently receiving medical treatment, GE added.

"We are working to determine the root cause of this incident and to provide proper support as needed," it said

The turbine collapse in Brazil is the fifth such incident involving GE turbines this year, even as the UK's biggest offshore windfarm begins power supply this week, underscoring broader sector momentum.

On 16 February, a turbine collapsed at NextEra Energy Resources’ Casa Mesa wind farm in New Mexico, US, while giant wind components were being transported to a project in Saskatchewan, Canada. The site uses GE’s 2.3-116 and 2.5-127 models.

The New Mexico incident was followed by another collapse in the US — as a Scottish North Sea wind farm resumed construction after Covid-19 — this time a GE 2.4-107 unit at Tradewind Energy’s Chisholm View 2 project in Oklahoma on 21 May.

Two GE turbines then collapsed at projects in July: a 2.5-116 unit at Invenergy’s Upstreamwind farm in Nebraska on 5 July, followed by a 1.7-103 model at the Actis Group-owned Ventos de São Clemente complex in Pernambuco, north-eastern Brazil, even as tidal power in Scotland generated enough electricity to power nearly 4,000 homes.

No employees were injured in the first four turbine collapses of the year, in contrast with concerns at a Hawaii geothermal plant over potential meltdown risk.

In response to the latest incident, GE Renewable Energy added: "It is too early to speculate about the root cause of this week’s turbine collapse.

"Based on our learnings from the previous turbine collapses, we have teams in place focused on containing and resolving these issues quickly, to ensure the safe and reliable operation of our turbines."

Iran Power Outage Protests surge as electricity blackouts, drought, and a looming heat wave spark unrest in Tehran, Shiraz, and more, with chants against leadership, strikes, and sanctions-driven economic pressures mounting.

Key Points

Protests across Iran over blackouts, drought, and economic strain challenge authorities and demand accountability.

✅ Rolling blackouts blamed on drought, heat wave, and surging demand.

✅ Chants target leadership amid strikes and wage, water shortages.

✅ Legitimacy questioned after low-turnout election and sanctions.

There have been protests in a number of cities in Iran amid rising public anger over widespread electricity blackouts.

Videos on social media appeared to show crowds in Shar-e Rey near Tehran, Shiraz, Amol and elsewhere overnight.

Some people can be heard shouting "Death to the dictator" and "Death to Khamenei" - a reference to Supreme Leader Ayatollah Ali Khamenei.

The government has apologised for the blackouts, which it has blamed on a severe drought and high demand.

Elsewhere, similar outages have had political repercussions, as a widespread power outage in Taiwan prompted a minister's resignation earlier this year.

President Hassan Rouhani explained in televised remarks on Tuesday morning that the drought meant most of the country's hydroelectric power plants were not operating, placing more pressure on thermal power plants, and that electricity consumption had surged as people used air conditioning to cope with the intense summer heat.

"I apologise to our dear people who have faced problems and suffering in the past few days and I urge them to co-operate [by cutting their electricity use]. People complain about power outages and they are right," Mr Rouhani said.

A video that has gone viral in recent days shows a woman complaining about the blackouts and corruption at a government office in the northern city of Gorgan and demanding that her comments be conveyed to "higher-ups like Mr Rouhani". "The only thing you have done is forcing hijab on us," she shouts.

The president has promised that the government will seek to resolve the problems within the next two or three weeks.

However, a power sector spokesman warned on Monday that consumption was exceeding the production capacity of Iran's power plants by 11GW, and said a "looming heat wave" could make the situation worse, as seen in Iraq's summer electricity crunch this year.

Iranians have also been complaining about water shortages and the non-payment of wages by some local authorities, while thousands of people working in Iran's oil industry have been on strike over pay and conditions, as officials discuss further energy cooperation with Iraq to ease supply pressures.

There was already widespread discontent at government corruption and the economic hardship caused by sanctions that were reinstated when the US abandoned a nuclear deal with Iran three years ago, even as Iran supplies about 40% of Iraq's electricity through cross-border sales.

Analysts say that after the historically low turnout in last month's presidential election, when more than half of the eligible voters stayed at home, the government is facing a serious challenge to its legitimacy.

Mr Rouhani will be succeeded next month by Ebrahim Raisi, a hard-line cleric close to Ayatollah Khamenei who won 62% of the vote after several prominent contenders were disqualified, while Iran finalizes power grid deals with Iraq to bolster regional ties.

The 60-year-old former judiciary chief has presented himself as the best person to combat corruption and solve Iran's economic problems, including ambitions to transmit electricity to Europe as a regional power hub.

But many Iranians and human rights activists have pointed to his human rights record, accusing him of playing a role in the executions of thousands of political prisoners in the 1980s and in the deadly crackdowns on mass anti-government protests in 2009 and 2019.

Birtle Transmission Line connects Manitoba Hydro to SaskPower, enabling 215 MW of clean hydroelectricity, improving grid reliability, supporting affordable rates, and advancing Green Infrastructure goals under the Investing in Canada Plan across Manitoba and Saskatchewan.

Key Points

A 46 km line moving up to 215 MW from Manitoba Hydro to SaskPower, improving reliability and supplying cleaner power.

✅ Enables interprovincial grid tie between Manitoba and Saskatchewan

✅ Delivers up to 215 MW of renewable hydroelectricity

✅ Supports affordable rates and lower GHG emissions

The federal government announced funding for the Birtle Transmission Line Monday morning.

The project will help Manitoba Hydro build a transmission line from Birtle South Station in the Municipality of Prairie View to the Manitoba–Saskatchewan border 46 kilometres northwest. Once completed, the new line will allow up to 215 megawatts of hydroelectricity to flow from the Manitoba Hydro power grid to the SaskPower power grid, similar to the Great Northern Transmission Line connecting Manitoba and Minnesota today.

The government said the transmission line would create a more stable energy supply, keep energy rates affordable and help Saskatchewan's efforts to reduce cumulative greenhouse-gas emissions in that province.

"The Government of Canada is proud to be working with Manitoba to support projects that create jobs and improve people's lives across the province. The Birtle Transmission Line will provide the region with reliable and greener energy, as seen with Canadian hydropower to New York projects, that will help protect our environment while laying the groundwork for clean economic growth," said Jim Carr, member of Parliament for Winnipeg South Centre, on behalf of Catherine McKenna, minister of infrastructure and communities.

The Government of Canada is investing more than $18.7 million, and the government of Manitoba is contributing more than $42 million in this project through the Green Infrastructure Stream of the Investing in Canada Plan, which also supports Atlantic grid improvements nationwide.

"The Province of Manitoba has one of the cleanest electricity grids in Canada and the world with over 99 per cent of our electricity generated from clean, renewable sources, rooted in Manitoba's hydro history," said Central Services Minister Reg Helwer. "The Made-in-Manitoba Climate and Green Plan is good not only for Manitoba but for Canada and globally."

Jay Grewal, president, and CEO of Manitoba Hydro said the funding is a great example of co-operation between the provincial and federal governments, including investments in smart grid technology that modernize local networks.

"We are very pleased that Manitoba Hydro's Birtle Transmission Project is among the first projects to receive funding under the Canada Infrastructure Program, and we would like to thank both levels of governments for recognizing the importance of the project as we strengthen ties with our neighbours in Saskatchewan, as U.S.-Canada transmission approvals advance elsewhere," said Grewal.

A spokesperson for Manitoba Hydro said it’s too early to say how many jobs will be created during construction, as final contracts have not yet been awarded.
