Precast concrete hot water pads are joining the short list of products designed to keep pigs snug and warm.

The challenge of keeping pigs warm and cozy during the two most stressful events in their lives - birth and weaning - has taken a new twist. A Canadian manufacturer has turned to hot water heat as an alternative to electric heat pads and heat lamps.

John Lichti, co-owner of Cozy Creep, an Ontario-based manufacturing company, began experimenting with hot water heating back in 1996.

The Cozy Creep underfloor heating system offers a low-temperature (84°F - 95°F) heat that warms the floor beneath the farrowing crate by circulating hot water through a maze of pipes encased in the concrete slab (or concrete overpour). A circulating pump returns the cooler water to the heat source where it is reheated in a closed-loop system.

Various forms of energy - natural gas, oil, propane, biofuel or electricity - can be used to power the hot water heater. Geothermal is perfectly suited for such applications, too, says Lichti.

In Lichti's first system, the hot water pipes were installed when the new concrete barn floors were poured.

“It worked extremely well,” he says. “The problem with pouring it in place is that it's labor intensive. The concrete has to be handled and finished properly. You need a plumber, welders, carpenters and concrete people. Everything has to fit together, so it was fairly expensive from a capital standpoint.”

Lichti had plans to expand his hog operation and wanted to retrofit an older barn. The cost for a concrete overpour was prohibitive, so he came up with a modular design. Pipes are pre-cast into 2x4 ft. concrete pads designed so they can be inserted into existing farrowing crate creep areas or nursery pens. Tubing is designed so 20-30 farrowing crates can be linked in a single, closed-loop system.

Because the pads are factory made, quality is consistent and installation is easy because pipes come out to the edge, says Lichti.

“All you have to do is hook up a pipe to the one coming out of the pad and run it to the next pad. Since one control system can handle a loop of 20 to 30 crates it's great for retrofits,” he adds.

Each two-and-a-half inch-thick concrete pad is treated with silica fume - the same technology being used on bridges. “It keeps salt from seeping into the concrete,” he explains. “It has a high ash content and it changes the particle size, making them very small so water doesn't seep in when the pads are washed with high pressure washers.”

An added advantage over hanging heaters with blower fans is the heat radiates from the floor up to the pigs' lying surface, minimizing drafts and circulating dust.

The first 30 units were tested in Lichti's barn.

“Since you're just heating the surface where the pig lays, you can keep the ambient temperature in the room quite a bit lower when using radiant heat,” says Lichti. “How much lower depends on your management style, but it could be as much as 10-12°F. lower for a 3-week old pig in a nursery.”

Lichti compared radiant heat against convection heating for 2,600 litters in an informal trial. His data showed that the weaning weight increased by 18% and preweaning mortality was significantly reduced - dropping from more than one pig/litter down to just over a half pig/litter.

Lichti says a practical advantage of the hot water pads is it eliminates the risks of malfunctioning, overheating or shocks from electric heat pads or heat lamps. And, they are competitively priced with electric heat pads, he adds.

“When it comes time to wash up, there's nothing in the way,” he says. “It's what clients comment on the most.”

Lichti estimates about 1.5 million Canadian piglets have been weaned on CozyCreep heat pads every year since 2001. The heat pads received Ontario's Agri-Food Industry Innovations Award in 2006.

Most units are currently being sold in Ontario and Manitoba, but the company plans to enter the United States market later this year.

Green hydrogen, green energy: inside Brazil's $5.4bn green hydrogen plant

Enegix Base One Green Hydrogen Plant will produce renewable hydrogen via electrolysis in Ceara, Brazil, leveraging 3.4 GW baseload renewables, offshore wind, and hydro to scale clean energy, storage, and export logistics.

 

Key Points

A $5.4bn Ceara, Brazil project to produce 600m kg of green hydrogen annually using 3.4 GW of baseload renewables.

✅ 3.4 GW baseload from hydro and offshore wind pipelines

✅ Targets 600m kg green hydrogen per year via electrolysis

✅ Focus on storage, transport, and export supply chains

 

In March, Enegix Energy announced some of the most ambitious hydrogen plans the world has ever seen. The company signed a memorandum of understanding (MOU) with the government of the Brazilian state of Ceará to build the world’s largest green hydrogen plant in the state on the country’s north-eastern coast, and the figures are staggering.

The Base One facility will produce more than 600 million kilograms of green hydrogen annually from 3.4GW of baseload renewable energy, and receive $5.4bn in investment to get the project off the ground and producing within four years.

Green hydrogen, hydrogen produced by electrolysis that is powered by renewables, has significant potential as a clean energy source. Already seeing increased usage in the transport sector, the power source boasts the energy efficiency and the environmental viability to be a cornerstone of the world’s energy mix.

Yet practical challenges have often derailed large-scale green hydrogen projects, from the inherent obstacle of requiring separate renewable power facilities to the logistical and technological challenges of storing and transporting hydrogen. Could vast investment, clever planning, and supportive governments and programs like the DOE’s hydrogen hubs initiative help Enegix to deliver on green hydrogen’s oft-touted potential?

Brazilian billions
The Base One project is exceptional not only for its huge scale, but the timing of its construction, with demand for hydrogen set to increase dramatically over the next few decades. Figures from Wood Mackenzie suggest that hydrogen could account for 1.4 billion tonnes of energy demand by 2050, one-tenth of the world’s supply, with green hydrogen set to be the majority of this figure.

Yet considering that, prior to the announcement of the Enegix project, global green hydrogen capacity was just 94MW, advances in offshore green hydrogen and the development of a project of this size and scope could scale up the role of green hydrogen by orders of magnitude.

“We really need to [advance clean energy] without any emissions on a completely clean, carbon neutral and net-zero framework, and so we needed access to a large amount of green energy projects,” explains Wesley Cooke, founder and CEO of Enegix, a goal aligned with analyses that zero-emissions electricity by 2035 is possible, discussing the motivation behind the vast project.

With these ambitious goals in mind, the company needed to find a region with a particular combination of political will and environmental traits to enable such a project to take off.


“When we looked at all of these key things: pipeline for renewables, access to water, cost of renewables, and appetite for renewables, Brazil really stood out to us,” Cooke continues. “The state of Ceará, that we’ve got an MOU with the government in at the moment, ticks all of these boxes.”

Ceará’s own clean energy plans align with Enegix’s, at least in terms of their ambition and desire for short-term development. Last October, the state announced that it plans to add 5GW of new offshore wind capacity in the next five years. With BI Energia alone providing $2.5bn in investment for its 1.2GW Camocim wind facility, there is significant financial muscle behind these lofty ambitions.

“One thing I should add is that Brazil is very blessed when it comes to baseload renewables,” says Cooke. “They have an incredibly high percentage of their country-wide energy that comes from renewable sources and a lot of this is in part due to the vast hydro schemes that they have for hydro dams. Not a lot of countries have that, and specifically when you’re trying to produce hydrogen, having access to vast amounts of renewables [is vital].”

Changing perceptions and tackling challenges
This combination of vast investment and integration with the existing renewable power infrastructure of Ceará could have cultural impacts too. The combination of state support for and private investment in clean energy offsets many of the narratives emerging from Brazil concerning its energy policies and environmental protections, even as debates over clean energy's trade-offs persist in Brazil and beyond, from the infamous Brumadinho disaster to widespread allegations of illegal deforestation and gold mining.

“I can’t speak for the whole of Brazil, but if we look at Ceará specifically, and even from what we’ve seen from a federal government standpoint, they have been talking about a hydrogen roadmap for Brazil for quite some time now,” says Cooke, highlighting the state’s long-standing support for green hydrogen. “I think we came in at the perfect time with a very solid plan for what we wanted to do, [and] we’ve had nothing but great cooperation, and even further than just cooperation, excitement around the MOU.”

This narrative shift could help overcome one of the key challenges facing many hydrogen projects, the idea that its practical difficulties render it fundamentally unsuitable for baseload power generation. By establishing a large-scale green hydrogen facility in a country that has recently struggled to present itself as one that is invested in renewables, the Base One facility could be the ultimate proof that such clean hydrogen projects are viable.

Nevertheless, practical challenges remain, as is the case with any energy project of this scale. Cooke mentions a number of solutions to two of the obstacles facing hydrogen production around the world: renewable energy storage and transportation of the material.

“We were looking at compressed hydrogen via specialised tankers [and] we were looking at liquefied hydrogen, [as] you have to get liquefied hydrogen very cool to around -253°, and you can use 30% to 40% of your total energy that you started with just to get it down to that temperature,” Cooke explains.

“The other aspect is that if you’re transporting this internationally, you really have to think about the supply chain. If you land in a country like Indonesia, that’s wonderful, but how do you get it from Indonesia to the customers that need it? What is the supply chain? What does that look like? Does it exist today?”

The future of green hydrogen
These practical challenges present something of a chicken and egg problem for the future of green hydrogen: considerable up-front investment is required for functions such as storage and transport, but the difficulties of these functions can scare off investors and make such investments uncommon.

Yet with the world’s environmental situation increasingly dire, more dramatic, and indeed risky, moves are needed to alter its energy mix, and Enegix is one company taking responsibility and accepting these risks.

“We need to have the renewables to match the dirty fuel types,” Cooke says. “This [investment] will really come from the decisions that are being made right now by large-scale companies, multi-billion-euro-per-year revenue companies, committing to building out large scale factories in Europe and Asia, to support PEM [hydrolysis].”

This idea of large-scale green hydrogen is also highly ambitious, considering the current state of the energy source. The International Renewable Energy Agency reports that around 95% of hydrogen comes from fossil fuels, so hydrogen has a long ways to go to clean up its own carbon footprint before going on to displace fossil fuel-driven industries.

Yet this displacement is exactly what Enegix is targeting. Cooke notes that the ultimate goal of Enegix is not simply to increase hydrogen production for use in a single industry, such as clean vehicles. Instead, the idea is to develop green hydrogen infrastructure to the point where it can replace coal and oil as a source of baseload power, leapfrogging other renewables to form the bedrock of the world’s future energy mix.

“The problem with [renewable] baseload is that they’re intermittent; the wind’s not always blowing and the sun’s not always shining and batteries are still very expensive, although that is changing. When you put those projects together and look at the levelised cost of energy, this creates a chasm, really, for baseload.

“And for us, this is really where we believe that hydrogen needs to be thought of in more detail and this is what we’re really evangelising about at the moment.”

A more hydrogen-reliant energy mix could also bring social benefits, with Cooke suggesting that the same traits that make hydrogen unwieldy in countries with established energy infrastructures could make hydrogen more practically viable in other parts of the world.

“When you look at emerging markets and developing markets at the moment, the power infrastructure in some cases can be quite messy,” Cooke says. “You’ve got the potential for either paying for the power or extending your transmission grid, but rarely being able to do both of those.

“I think being able to do that last mile piece, utilising liquid organic hydrogen carrier as an energy vector that’s very cost-effective, very scalable, non-toxic, and non-flammable; [you can] get that power where you need it.

“We believe hydrogen has the potential to be very cost-effective at scale, supporting a vision of cheap, abundant electricity over time, but also very modular and usable in many different use cases.”

Hydro One, Avista to ask U.S. regulator to reconsider order against acquisition

Hydro One Avista Takeover faces Washington UTC scrutiny as regulators deny approval; companies plan a reconsideration petition, citing acquisition terms, governance concerns, merger risks, EPS dilution, and balance sheet impacts across regulated utility operations.

 

Key Points

A $6.7B bid by Hydro One to buy Avista, denied by Washington UTC on governance risk, under reconsideration petition.

✅ UTC denied over potential provincial interference.

✅ Petition for reconsideration due by Dec. 17.

✅ Deal seen diluting EPS, weakening balance sheet.

 

Hydro One Ltd. and Avista Corp. say they plan to formally request that the Washington Utilities and Transportation Commission reconsider its order last week denying approval of the $6.7-billion takeover, which previously received U.S. antitrust clearance from federal regulators, of the U.S.-based energy utility.

The two companies say they will file a petition no later than Dec. 17 but haven't indicated on what grounds they are making the request, even as investor concerns about Hydro One persist.

Under Washington State law, the UTC has 20 days to consider the petition, otherwise it is deemed to be denied.

If it reconsiders its decision, the UTC can modify the prior order or take any actions it deems appropriate, similar to provincial rulings such as the OEB decision on Hydro One's first combined T&D rates, including extending deliberations.

Washington State regulators said they would not allow Ontario's largest utility to buy Avista for fear the provincial government, which owns 47 per cent of Hydro One's shares and recently prompted a CEO and board exit at the utility, might meddle in Avista's operations.

Hydro One's shares have risen since the order because the deal, announced in July 2017, would have eroded earnings per share and weakened Hydro One's balance sheet, according to analysts, even as the company reported a one-time-boosted Q2 profit earlier this year.

NY Governor Cuomo Announces Green New Deal Included in 2019 Executive Budget

New York Green New Deal accelerates clean energy and climate action, targeting carbon neutrality with renewable energy, offshore wind, solar, energy storage, and green jobs while advancing environmental justice and economy-wide decarbonization.

 

Key Points

New York's plan for 100% clean power by 2040 and 70% renewables by 2030, with a just transition and green jobs.

✅ 100% carbon-free electricity by 2040; 70% renewables by 2030

✅ 9,000 MW offshore wind and 3,000 MW energy storage targets

✅ Just transition focuses on jobs, equity, and affordability

 

New York Governor Andrew M. Cuomo announced the Green New Deal, a nation-leading clean energy and jobs agenda that will aggressively put New York State on a path to net-zero electricity and economy-wide carbon neutrality, is included in the 2019 Executive Budget. The landmark plan provides for a just transition to clean energy that spurs growth of the green economy and prioritizes the needs of low- to moderate-income New Yorkers.

"Climate change is a reality, and the consequences of delay are a matter of life and death. We know what we must do. Now we have to have the vision, the courage, and the competence to get it done," Governor Cuomo said. "While the federal government shamefully ignores the reality of climate change and fails to take meaningful action, we are launching the first-in-the-nation Green New Deal to seize the potential of the clean energy economy, set nation's most ambitious goal for carbon-free power, and ultimately eliminate our entire carbon footprint."

During Governor Cuomo's first two terms, New York banned fracking of natural gas, committed to phasing out coal power by 2020, mandated 50 percent renewable power by 2030, and established the U.S. Climate Alliance to uphold the Paris Agreement, reflecting the view that decarbonization is irreversible under a clean energy economy. Under the Reforming the Energy Vision agenda, New York has held the largest renewable energy procurements in U.S. history, solar has increased nearly 1,500 percent, and offshore wind is poised to transform the State's electricity supply to be cleaner and more sustainable. Through Governor Cuomo's Green New Deal, New York will take the bold next steps to secure a clean energy future that protects the environment for generations to come while growing the clean energy economy.

 

100 Percent Clean Power by 2040 Coupled with New Nation-leading Renewable Energy Mandates

The Green New Deal will statutorily mandate New York's power be 100 percent carbon-free by 2040, the most aggressive goal in the United States and five years ahead of a target recently adopted by California state policymakers. The cornerstone of this new mandate is a significant increase of New York's successful Clean Energy Standard mandate from 50 percent to 70 percent renewable electricity by 2030. This globally unprecedented ramp-up of renewable energy will include:

  • Quadrupling New York's offshore wind target to 9,000 megawatts by 2035, up from 2,400 megawatts by 2030
  • Doubling distributed solar deployment to 6,000 megawatts by 2025, up from 3,000 megawatts by 2023
  • More than doubling new large-scale land-based wind and solar resources through the Clean Energy Standard
  • Maximizing the contributions and potential of New York's existing renewable resources
  • Deploying 3,000 megawatts of energy storage by 2030, up from 1,500 megawatts by 2025
  • Develop an Implementation Plan to Make New York Carbon Neutral

The Green New Deal will create the State's first statutory Climate Action Council, comprised of the heads of relevant State agencies and other workforce, environmental justice, and clean energy experts to develop a comprehensive plan to make New York carbon neutral by significantly and cost-effectively reducing emissions from all major sources, including electricity, transportation, buildings, industry, commercial activity, and agriculture. The Climate Action Council will consider a range of possible options, including the feasibility of working with the U.S. Climate Alliance to create a new multistate emissions reduction program that covers all sectors of the economy, including transportation and industry, and exploring ways to leverage the successful Regional Greenhouse Gas Initiative to drive transformational investment in the clean energy economy and support a just transition.

At the national level, a historic climate deal is reshaping incentives and standards for clean energy deployment across the country.

The Green New Deal will also include an ambitious strategy to move New York's statewide building stock to carbon neutrality. The agenda includes:

Advancing legislative changes to strengthen building energy codes and establish appliance efficiency standards

Directing State agencies to ensure that their facilities uphold the strongest energy efficiency and sustainability standards

Developing a Net Zero Roadmap to chart a course to statewide carbon neutrality in buildings

A Multibillion Dollar Green New Deal Investment in the Clean Tech Economy that will Reduce Greenhouse Gas Emissions

Demonstrating New York's immediate commitment to implementing the nation's most ambitious clean energy agenda and creating high-quality clean energy jobs, Governor Cuomo is announcing $1.5 billion in competitive awards to support 20 large-scale solar, wind and energy storage projects across upstate New York. These investments will add over 1,650 megawatts of capacity and generate over 3,800,000 megawatt-hours of renewable energy annually - enough to power nearly 550,000 homes and create over 2,600 short and long-term jobs. Combined with the renewable energy projects previously announced under the Clean Energy Standard, New York has now awarded more than $2.9 billion to 46 projects statewide, enough to power over one million households.

The Green New Deal also includes new investments to jumpstart New York's offshore wind energy industry and support the State's world-leading target of 9,000 megawatts by 2035. New York will invest up to $200 million in port infrastructure to match private sector investment in regional development of offshore wind. This multi-location investment represents the nation's largest infrastructure commitment to offshore wind and solidifies New York's position as the hub of the burgeoning U.S. offshore wind industry.

These new investments build upon a $250 million commitment to electric vehicle infrastructure by the New York Power Authority's EVolve program, $3.5 billion in private investment in distributed solar driven by NYSERDA's NY-Sun program, and NY Green Bank transactions mobilizing nearly $1.75 billion in private capital for clean energy projects.

 

A Just Transition to a Clean Energy Economy

Deliver Climate Justice for Underserved Communities: The Green New Deal will help historically underserved communities prepare for a clean energy future and adapt to climate change by:

Giving communities a seat at the table by codifying the Environmental Justice and Just Transition Working Group into law and incorporating it into the planning process for the Green New Deal's implementation.

Directing the State's low-income energy task force to identify reforms to achieve greater impact of the public energy funds expended each year in order to increase the effect of funds and initiatives that target energy affordability to underserved communities.

Directing each of the State's ten Regional Economic Development Councils to develop an environmental justice strategy for their region.

Finance a Property Tax Compensation Fund to Help Communities Transition to the Clean Energy Economy: Governor Cuomo is introducing legislation to finance the State's $70 million Property Tax Compensation Fund to continue helping communities directly affected by the transition away from dirty and obsolete energy industries and toward the new clean energy economy. Specifically, this funding will protect communities impacted by the retirement of conventional power generation facilities.

Protect Labor Rights: To ensure creation of high-quality clean energy jobs, large-scale renewable energy projects supported by the Green New Deal will require prevailing wage, and the State's offshore wind projects will be supported by a requirement for a Project Labor Agreement.

Develop the Clean Tech Workforce: To prepare New York's workforce for the transition, New York State will take new steps to support workforce development, including establishing a New York State Advisory Council on Offshore Wind Economic and Workforce Development, as well as investing in an offshore wind training center that will provide New Yorkers with the skills and safety training required to construct this clean energy technology in New York.   

Richard Kauffman, Chairman of Energy and Finance for New York, said, "Governor Cuomo's Green New Deal will advance New York State further into the clean energy future, and we won't let the Trump Administration push us backwards. Governor Cuomo's new commitments ensure New York is the undisputed national clean energy and climate leader, and we will continue to build upon the foundations of the REV agenda to achieve a sustainable economy and healthy environment for generations of New Yorkers to come."

Alicia Barton, President and CEO, NYSERDA, said, "Climate scientists have made frighteningly clear that averting the worst effects of climate change will require bold action, not incremental steps, and Governor Cuomo's Green New Deal boldly goes where no others have before. His unwavering climate agenda includes the most aggressive clean energy target in U.S. history, the largest commitments to renewable energy and to offshore wind in the nation, a massive mobilization of clean energy jobs and an unprecedented investment in offshore wind port infrastructure. Together these actions make New York the clear national leader in the fight against climate change, and will show the world that New York can and will achieve a clean energy future for the sake of future generations."

DEC Commissioner Basil Seggos said, "The threat of climate change calls for bold action like Governor Cuomo's comprehensive agenda to make New York State carbon neutral. The Green New Deal ensures New York is continuing our nation-leading efforts to capitalize on the economic potential of the clean energy economy, while making sure those most vulnerable to climate change are benefitting from the state's efforts and investments. I look forward to working with my agency and authority partners on the Climate Action Council to develop and implement meaningful solutions to reduce greenhouse gas emissions from all sectors of our economy."  

John B. Rhodes, CEO, Department of Public Service, said, "With this nation-leading Green New Deal, Governor Cuomo puts New York on the path to fully clean electricity and to carbon neutrality with the strongest renewable energy goals in the nation. This will deliver the energy system that New York needs - cost-effective, reliable, and 100% clean.”

Swiss Earthquake Service and ETH Zurich aim to make geothermal energy safer

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.

Ontario's electricity operator kept quiet about phantom demand that cost customers millions

IESO Fictitious Demand Error inflated HOEP in the Ontario electricity market, after embedded generation was mis-modeled; the OEB says double-counted load lifted wholesale prices and shifted costs via the Global Adjustment.

 

Key Points

An IESO modeling flaw that double-counted load, inflating HOEP and charges in Ontario's wholesale market.

✅ Double-counted unmetered load from embedded generation

✅ Inflated HOEP; shifted costs via Global Adjustment

✅ OEB flagged transparency; exporters paid more

 

For almost a year, the operator of Ontario’s electricity system erroneously counted enough phantom demand to power a small city, causing prices to spike and hundreds of millions of dollars in extra charges to consumers, according to the provincial energy regulator.

The Independent Electricity System Operator (IESO) also failed to tell anyone about the error once it noticed and fixed it.

The error likely added between $450 million and $560 million to hourly rates and other charges before it was fixed in April 2017, according to a report released this month by the Ontario Energy Board’s Market Surveillance Panel.

It did this by adding as much as 220 MW of “fictitious demand” to the market starting in May 2016, when the IESO started paying consumers who reduced their demand for power during peak periods. This involved the integration of small-scale embedded generation (largely made up of solar) into its wholesale model for the first time.

The mistake assumed maximum consumption at such sites without meters, and double-counted that consumption.

The OEB said the mistake particularly hurt exporters and some end-users, who did not benefit from a related reduction of a global adjustment rate applicable to other customers.

“The most direct impact of the increase in HOEP (Hourly Ontario Energy Price) was felt by Ontario consumers and exporters of electricity, who paid an artificially high HOEP, to the benefit of generators and importers,” the OEB said.

The mix-up did not result in an equivalent increase in total system costs, because changes to the HOEP are offset by inverse changes to a electricity cost allocation mechanism such as the Global Adjustment rate, the OEB noted.


A chart from the OEB's report shows the time of day when fictitious demand was added to the system, and its influence on hourly rates.

Peak time spikes
The OEB said that the fictitious demand “regularly inflated” the hourly price of energy and other costs calculated as a direct function of it.

For almost a year, Ontario's electricity system operator @IESO_Tweets erroneously counted enough phantom demand to power a small city, causing price spikes and hundreds of millions in charges to consumers, @OntEnergyBoard says. @5thEstate reports.

It estimated the average increase to the HOEP was as much as $4.50/MWh, but that price spikes, compounded by scheduled OEB rate changes, would have been much higher during busier times, such as the mid-morning and early evening.

“In times of tight supply, the addition of fictitious demand often had a dramatic inflationary impact on the HOEP,” the report said.

That meant on one summer evening in 2016 the hourly rate jumped to $1,619/MWh, it said, which was the fourth highest in the history of the Ontario wholesale electricity market.

“Additional demand is met by scheduling increasingly expensive supply, thus increasing the market price. In instances where supply is tight and the supply stack is steep, small increases in demand can cause significant increases in the market price.

The OEB questioned why, as of September this year, the IESO had failed to notify its customers or the broader public, amid a broader auditor-regulator dispute that drew political attention, about the mistake and its effect on prices.

“It's time for greater transparency on where electricity costs are really coming from,” said Sarah Buchanan, clean energy program manager at Environmental Defence.

“Ontario will be making big decisions in the coming years about whether to keep our electricity grid clean, or burn more fossil fuels to keep the lights on,” she added. “These decisions need to be informed by the best possible evidence, and that can't happen if critical information is hidden.”

In a response to the OEB report on Monday, the IESO said its own initial analysis found that the error likely pushed wholesale electricity payments up by $225 million. That calculation assumed that the higher prices would have changed consumer behaviour, while upcoming electricity auctions were cited as a way to lower costs, it said.

In response to questions, a spokesperson said residential and small commercial consumers would have saved $11 million in electricity costs over the 11-month period, even as a typical bill increase loomed province-wide, while larger consumers would have paid an extra $14 million.

That is because residential and small commercial customers pay some costs via time-of-use rates, including a temporary recovery rate framework, the IESO said, while larger customers pay them in a way that reflects their share of overall electricity use during the five highest demand hours of the year.

The IESO said it could not compensate those that had paid too much, given the complexity of the system, and that the modelling error did not have a significant impact on ratepayers.

While acknowledging the effects of the mistake would vary among its customers, the IESO said the net market impact was less than $10 million, amid ongoing legislation to lower electricity rates in Ontario.

It said it would improve testing of its processes prior to deployment and agreed to publicly disclose errors that significantly affect the wholesale market in the future.

Trudeau vows to regulate oil and gas emissions, electric car sales

Canada Oil and Gas Emissions Cap sets five-year targets to cut sector emissions toward net-zero by 2050, alongside an EV mandate, carbon pricing signals, and support for carbon capture, clean energy jobs, climate policy.

 

Key Points

A federal policy to regulate and reduce oil and gas emissions via 5-year targets, reaching net-zero by 2050.

✅ Regulated 5-year milestones to cut oil and gas emissions to net-zero by 2050

✅ Interim EV mandate: 50% by 2030; 100% zero-emission sales by 2035

✅ $2B fund for clean energy jobs in oil- and gas-reliant communities

 

Liberal Leader Justin Trudeau vowed to regulate total emissions from Canada’s oil and gas producers as he laid out his first major climate change promises of the campaign Sunday, a plan that was welcomed by several environmental and climate organizations.

Trudeau said that if re-elected, the Liberals will set out regulated five-year targets for emissions from oil and gas production to get them to net-zero emissions by 2050, a goal that, according to an IEA report will require more electricity, but also create a $2 billion fund to create jobs in oil and gas-reliant communities in Alberta, Saskatchewan and Newfoundland and Labrador.

“Let’s be realistic, over a quarter of Canada’s emissions come from our oil and gas sector. We need the leadership of these industries to decarbonize our country,” Trudeau said.

“That’s why we’ll make sure oil and gas emissions don’t increase and instead go down with achievable milestones,” while ensuring local economies can prosper.“

The Liberals are also introducing an interim electric vehicle mandate, which will require half the cars sold in Canada to be zero-emission by 2030, and because cleaning up electricity is critical to meeting climate pledges, the policy pairs with power-sector decarbonization, ahead of the final mandated target of 100 per cent by 2035.

Trudeau spoke in Cambridge, Ont., where protesters once again made an appearance amid a visible police presence. Officers carried one woman off the property when she refused to leave when asked.

Trudeau alluded to the protesters and their actions, which included sounding sirens and chanting expletives, as he defended his government’s record on climate change including progress in the electricity sector nationally, and touted its new plan.

“Sirens in the background may remind us that this is a climate emergency. That’s why we will move faster and be bolder,” he said.

Canada’s largest oilsands producers have already committed to reaching net zero greenhouse gas emissions by 2050, but the policy proposed Sunday “calls the oil companies’ bluff” by making those goals a legislated requirement, said Keith Stewart, senior energy strategist with Greenpeace Canada.

The new timeline for electric vehicles also “sends a clear signal to auto companies to get cracking (and build them here),” he said on Twitter, even as proposals like a fully renewable grid by 2030 are debated today. “We’d like to see this happen faster but the shift away from voluntary targets to requirements is big.”


Merran Smith, executive director of Clean Energy Canada, a climate program at Simon Fraser University, said clean electricity, clean transportation and “phasing out oil and gas with accountable milestones” must be key priorities over the next decade, aligning with Canada’s race to net-zero and the role of renewable energy.

“Today’s announcement, which checks all of these boxes, is not just good ambition_it’s good policy. Policy that will drive down carbon pollution and drive up clean job growth and economic competitiveness. It is policy that will drive Canada forward with cleaner cars, power Canada with clean electricity, and invest in businesses that will last such as battery manufacturing, electric vehicle manufacturing and low carbon steel,” Smith said in an email.

Michael Bernstein, executive director of the climate policy organization Clean Prosperity, said the promises laid out Sunday offer a “strong boost” to the federal government’s previous climate commitments.

He said the organization prefers market incentives such as carbon pricing, that spur innovation over further regulation. But since the largest oilsands companies have already committed to reaching net-zero emissions, he said the newly unveiled policy could provide some support.

“ First, I would encourage the Liberal Party to release independent modelling showing the types of emissions reductions they expect to achieve with their new package of policies. Second, many policies are referred to in general terms so I hope the Liberal Party will provide further details in the coming days,” he said.

“Finally, the document does not specifically mention carbon capture or carbon dioxide removal technologies but both technologies will be critical to achieve some of the pledges in today’s announcement, especially reaching net-zero emissions in the oil a gas sector.”

NDP Leader Jagmeet Singh painted the announcement as the latest in a string of “empty promises” from the Liberals on climate change, saying Canada has the highest increase in greenhouse gas emissions among all G7 countries, and that provinces like B.C. risk missing 2050 targets as well, he argued.

“Climate targets mean nothing when you don’t act on them. We can’t afford more of Justin Trudeau’s empty words on climate change,” he said in a statement.

The Trudeau Liberals submitted new targets to the United Nations in July, promising that Canada will curb emissions by 40 to 45 per cent from 2005 levels by 2030, building on the net-zero by 2050 plan announced earlier, officials say.
