Energy corridor moratorium lifted

Texas Deep Freeze Energy Crisis strains grids as polar vortex triggers rolling blackouts, record natural gas and electricity prices, refinery shutdowns, WTI gains, and scarcity pricing across Texas, Oklahoma, SPP, and Mexico.

Key Points

A polar vortex slamming Texas energy: outages, record power prices, gas spikes, and reduced oil output.

✅ Record gas trades near $500/mmBtu; power hits $6,000/MWh

✅ WTI tops $60 as Texas shuts in ~1 million bpd

✅ Rolling blackouts across SPP; ERCOT scarcity pricing

A deep freeze is roiling electricity markets in more than a dozen U.S. states, leading to record-setting prices for electricity and natural gas, knocking oil production off line and shutting down some of North America’s largest refineries.

“It’s freakishly cold,” said Eric Fell, a senior natural gas analyst with Wood Mackenzie in Houston, where record cold temperatures and snow have blanketed the city, caused rolling power outages, shut down refineries and sent both natural gas and electricity prices soaring.

'It’s freakishly cold': Deep freeze slams North American energy sector

The polar vortex has led to freezing temperatures in every county in Texas, the largest energy-producing state in the U.S., and caused massive disruptions across the North American energy complex, triggering Texas power outages as far south as Mexico.

As the plunge in temperatures forced oil companies to shut in an estimated one million barrels of oil production in Texas on Monday, the West Texas Intermediate benchmark price rose above the US$60 per barrel threshold for the first time in a year to settle up 1 per cent, or US65 cents, at US$60.12 per barrel.

President Joe Biden declared an emergency on Monday, unlocking federal assistance to Texas.

People carry groceries from a local gas station on Monday in Austin, Texas. Winter storm Uri has brought historic cold weather to Texas, causing traffic delays and power outages. 

Frozen wind farms are just a small piece of Texas’s power grid woes right now.

Fell said regional natural gas and electricity prices in Oklahoma and Texas broke U.S. records over the weekend.

On Friday, Oklahoma gas transmission prices averaged US$350 per million British thermal units and Fell said one trade went as high as US$600 per mmBtu. In parts of the Texas panhandle and elsewhere, prices jumped to US$200, “all of which individually would have been new records,” Fell said, noting the previous record was US$160.

On Monday, natural gas for physical delivery in the U.S. was trading for as much as US$500 per mmBtu as demand for the heating and power plant fuel soared.  Spot gas has been trading for hundreds of dollars across the central U.S. since Thursday with a surge in heating demand triggering widespread blackouts and sending electricity prices soaring. The fuel normally trades in the region for less than US$3 per mmBtu.

Similarly, electricity prices in Texas surged to US$6,000 per megawatt hour on Monday, as U.S. power companies grapple with supply-chain constraints, which Fell said is “100 times the normal price.”

“You’re seeing scarcity pricing in power and gas. The only thing that’s different this time is it’s staying there – it’s not just an hour or two hours, it’s the whole day,” he said.

The blast of Arctic cold, which has blanketed Canada and much of the U.S., has created a massive draw on natural gas supplies, used both for home heating and industrial uses like electricity generation.

Little Rock, Ark.-based Southwest Power Pool, which coordinates electricity distribution for parts of 14 states including Oklahoma Kansas, Nebraska and even as far north as North Dakota, announced rolling blackouts across its network on Monday as a result of the power outages.

“In our history as a grid operator, this is an unprecedented event and marks the first time SPP has ever had to call for controlled interruptions of service” SPP’s executive vice-president and chief operating officer Lanny Nickell said in a release, adding the move was “a last resort” to “prevent circumstances from getting worse.”

The frigid conditions have led to a surge in natural gas prices across the continent, including in Alberta where the AECO benchmark price jumped to a seven-year high of $6.36 per thousand cubic feet last week, a price not seen since 2014.

Energy systems in Texas and Oklahoma, which are major energy exporters to other U.S. states, are built to withstand severe heat – not extreme cold. The result is a disruption to the gas supply at exactly the time the U.S. energy system is demanding those molecules.

“Given how far south it’s gone into Texas, this is where you have a lot of gas production that isn’t properly winterized,” said Jeremy McCrea, an analyst with Raymond James covering the natural gas industry.

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.

Autonomous Energy Kites harness offshore wind on floating platforms, using carbon fiber wings, tethers, and rotors to generate grid electricity; an airborne wind energy solution backed by Alphabet's Makani to cut turbine costs.

Key Points

Autonomous Energy Kites are tethered craft that capture winds with rotors, generating grid power from floating platforms.

✅ Flies circles on tethers; rotors drive generators to feed the grid.

✅ Operates over deep-sea winds where fixed turbines are impractical.

✅ Lighter, less visual impact, and lower installation costs offshore.

One company's self-flying energy kite may be the answer to increasing wind power around the world, alongside emerging wave power solutions as well.

California-based Makani -- which is owned by Google's parent company, Alphabet -- is using power from the strongest winds found out in the middle of the ocean, where the offshore wind sector has huge potential, typically in spots where it's a challenge to install traditional wind turbines. Makani hopes to create electricity to power communities across the world.

Despite a growing number of wind farms in the United States and the potential of this energy source, lessons from the U.K. underscore how to scale, yet only 6% of the world's electricity comes from wind due to the the difficulty of setting up and maintaining turbines, according to the World Wind Energy Association.

When the company's co-founders, who were fond of kiteboarding, realized deep-sea winds were largely untapped, they sought to make that energy more accessible. So they built an autonomous kite, which looks like an airplane tethered to a base, to install on a floating platform in water, as part of broader efforts to harness oceans and rivers for power across regions. Tests are currently underway off the coast of Norway.

"There are many areas around the world that really don't have a good resource for renewable power but do have offshore wind resources," Makani CEO Fort Felker told Rachel Crane, CNN's innovation correspondent. "Our lightweight kites create the possibility that we could tap that resource very economically and bring renewable power to hundreds of millions of people."

This technology is more cost-efficient than a traditional wind turbine, which is a lot more labor intensive and would require lots of machinery and installation.

The lightweight kite, which is made of carbon fiber, has an 85-foot wingspan. The kite launches from a base station and is constrained by a 1,400-foot tether as it flies autonomously in circles with guidance from computers. Crosswinds spin the kite's eight rotors to move a generator that produces electricity that's sent back to the grid through the tether.

The kites are still in the prototype phase and aren't flown constantly right now as researchers continue to develop the technology. But Makani hopes the kites will one day fly 24/7 all year round. When the wind is down, the kite will return to the platform and automatically pick back up when it resumes.

Chief engineer Dr. Paula Echeverri said the computer system is key for understanding the state of the kite in real time, from collecting data about how fast it's moving to charting its trajectory.

Echeverri said tests have been helpful in establishing what some of the challenges of the system are, and the team has made adjustments to get it ready for commercial use. Earlier this year, the team successfully completed a first round of autonomous flights.

Working in deeper water provides an additional benefit over traditional wind turbines, according to Felker. By being farther offshore, the technology is less visible from land, and the growth of offshore wind in the U.K. shows how coastal communities can adapt. Wind turbines can be obtrusive and impact natural life in the surrounding area. These kites may be more attractive to areas that wish to preserve their scenic coastlines and views.

It's also desirable for regions that face constraints related to installing conventional turbines -- such as island nations, where World Bank support is helping developing countries accelerate wind adoption, which have extremely high prices for electricity because they have to import expensive fossil fuels that they then burn to generate electricity.

Makani isn't alone in trying to bring novelty to wind energy. Several others companies such as Altaeros Energies and Vortex Bladeless are experimenting with kites of their own or other types of wind-capture methods, such as underwater kites that generate electricity, a huge oscillating pole that generates energy and a blimp tethered to the ground that gathers winds at higher altitudes.

Raindrop Triboelectric Energy Harvesting converts falling water into electricity using Teflon (PTFE) on indium tin oxide and an aluminum electrode, forming a transient water bridge; a low frequency nanogenerator for renewable, static electricity harvesting.

Key Points

A method using PTFE, ITO, and an aluminum electrode to turn raindrop impacts into low frequency electrical power.

✅ PTFE on ITO boosts charge transfer efficiency.

✅ Water bridge links electrodes for rapid discharge.

✅ Low frequency output suits continuous energy harvesting.

Scientists at the City University of Hong Kong have used a Teflon-coated surface and a phenomenon called triboelectricity to generate a charge from raindrops. “Here we develop a device to harvest energy from impinging water droplets by using an architecture that comprises a polytetrafluoroethylene [Teflon] film on an indium tin oxide substrate plus an aluminium electrode,” they explain in their new paper in Nature as a step toward cheap, abundant electricity in the long term.

Triboelectricity itself is an old concept. The word means “friction electricity”—from the Greek tribo, to rub or wear down, which is why a diatribe tires you out—and dates back a long, long time. Static electricity is the most famous kind of triboelectric, and related work has shown electricity from the night sky can be harvested as well in niche setups. In most naturally occurring kinds, scientists have studied triboelectric in order to avoid its effects, like explosions inside of grain silos or hospital workers touching off pure oxygen. (Blowing sand causes an electric field, and NASA even worries about static when astronauts eventually land on Mars.)

One of the most studied forms of intentional and useful triboelectric is in systems such as ocean wave generators where the natural friction of waves meets nanogenerators of triboelectric energy. These even already use Teflon, which has natural conductivity that makes it ideal for this job. But triboelectricity is chaotic, and harnessing it generally involves a bunch of complicated, intersecting variables that can vary with the hourly weather. Promises of static electricity charging devices have often been, well, so much hot, sandy wind.

The scientists at City University of Hong Kong used triboelectric ideas to turn falling raindrops into energy. They say previous versions of the same idea were not very efficient, with materials that didn’t allow for high-fidelity transfer of electrical charge. (Many sources of renewable energy aren’t yet as efficient to turn into power, both because of developing technology and because their renewability means even less efficient use could be better than, for example, fossil fuels, and advances in renewable energy storage could help.)

“[A]chieving a high density of electrical power generation is challenging,” the team explains in its paper. “Traditional hydraulic power generation mainly uses electromagnetic generators that are heavy, bulky, and become inefficient with low water supply.” Diversifying how power is generated by water sources such as oceans and rivers is good for the existing infrastructure as well as new installations.

The research team found that as simulated raindrops fell on their device, the way the water accumulated and spread created a link between their two electrodes, one Teflon-coated and the other aluminum. This watery de facto wire link closes the loop and allows accumulated energy to move through the system. Because it’s a mechanical setup, it’s not limited to salty seawater, and because the medium is already water, its potential isn’t affected by ambient humidity either.

Raindrop energy is very low frequency, which means this tech joins many other existing pushes to harvest continuously available, low frequency natural energy, including underwater 'kites' that exploit steady currents. To make an interface that increases “instantaneous power density by several orders of magnitude over equivalent devices,” as the researchers say they’ve done here, could represent a major step toward feasibility in triboelectric generation.

Alberta Electricity Rate Cap stays despite carbon tax repeal, keeping the Regulated Rate Option at 6.8 cents/kWh. Levy funds cover market gaps as the UCP reviews NDP policies to maintain affordable utility bills.

Key Points

Program capping RRO power at 6.8 cents/kWh, using levy funds to offset market prices while the UCP reviews policy.

✅ RRO cap fixed at 6.8 cents/kWh for eligible customers

✅ Levy funds pay generators when market prices exceed the cap

✅ UCP reviewing NDP policies to ensure affordable rates

Alberta's carbon tax has been cancelled, but a consumer price cap on electricity — which the levy pays for — is staying in place for now.

June electricity rates are due out on Monday, about four days after the new UCP government did away with the carbon charge on natural gas and vehicle fuel.

Part of the levy's revenue was earmarked by the previous NDP government to keep power prices at or below 6.8 cents per kilowatt hour under new electricity rules set by the province.

"The Regulated Rate Option cap of 6.8 cents/kWh was implemented by the previous government and currently remains in effect. We are reviewing all policies put in place by the former government and will make decisions that ensure more affordable electricity rates for job-creators and Albertans," said a spokesperson for Alberta's energy ministry in an emailed statement.

Albertans with regulated rate contracts and all City of Medicine Hat utility customers only pay that amount or less, though some Alberta ratepayers have faced deferral-related arrears.

If the actual market price rises above that, the difference is paid to generators directly from levy funds, a buffer that matters as experts warn prices are set to soar later this year.

The government has paid more than $55 million to utilities over the past year ending in March 2019, due to that electricity price cap being in place.

Alberta Energy says the price gap program will continue, at least for the time being, amid electricity policy changes being considered.

Germany net-zero roadmap charts coal phase-out by 2030, rapid renewables buildout, energy storage, and hydrogen-ready gas engines to cut emissions and lower LCOE by 34%, unlocking a resilient, flexible, low-cost power system by 2040.

Key Points

Plan to phase out coal by 2030 and gas by 2040, scaling renewables, storage, and hydrogen to cut LCOE and emissions.

✅ Coal out by 2030; gas phased 2040 with hydrogen-ready engines

✅ Add 19 GW/yr renewables; 30 GW storage by 2040

✅ 34% lower LCOE, 23% fewer emissions vs slower path

Germany can achieve significant reductions in emissions and the cost of electricity by phasing out coal in 2030 under its coal phase-out plan but must have a clear plan to ramp up renewables and pivot to sustainable fuels in order to achieve net-zero, according to a new whitepaper from Wartsila.

The modelling, published in Wärtsilä new white paper ‘Achieving net-zero power system in Germany by 2040’, compares the current plan to phase out coal by 2030 and gas by 2045 with an accelerated plan, where gas is phased out by 2040. By accelerating the path to net-zero, Germany can unlock a 34% reduction in the levelised cost of energy, as well as a 23% reduction in the total emissions, or 562 million tonnes of carbon dioxide in real terms.

The modelling offers a clear, three-step roadmap to achieve net-zero: rapidly increase renewables, energy storage and begin future-proofing gas engines in this decade; phase out coal by 2030; and phase out gas by 2040, converting remaining engines to run on sustainable fuels.

The greatest rewards are available if Germany front-loads decarbonisation. This can be done by rapidly increasing renewable capacity, adding 19 GW of wind and solar PV capacity per year. It must also add a total of 30GW of energy storage by 2040.

Håkan Agnevall, President and CEO of Wärtsilä Corporation said: “Germany stands on the precipice of a new, sustainable energy era. The new Federal Government has indicated its plans to consign coal to history by 2030. However, this is only step one. Our white paper demonstrates the need to implement a three-step roadmap to achieve net-zero. It is time to put a deadline on fossil fuels and create a clear plan to transition to sustainable fuels.”

While a rapid coal phase-out has been at the centre of recent climate policy debates, including the ongoing nuclear debate over Germany’s energy mix, the pathway to net-zero is less clear. Wärtsilä’s modelling shows that gas engines should be used to accelerate the transition by providing a short-term bridge to enable net zero and navigate the energy transition while balancing the intermittency of renewables until sustainable fuels are available at scale.

However, if Germany follows the slower pathway and reaches net-zero by 2045, it risks becoming reliant on gas as baseload power for much of the 2030s amid renewable expansion challenges that persist, potentially harming its ability to reach its climate goals. 

Creating the infrastructure to pivot to sustainable fuels is one of the greatest challenges facing the German system. The ability to convert existing capacity to run purely on hydrogen via hydrogen-ready power plants will be key to reaching net-zero by 2040 and unlocking the significant system-wide benefits on offer.

Jan Andersson, General Manager of Market Development in Germany, Wärtsilä Energy added: “To reach the 2040 target and unlock the greatest benefits, the most important thing that Germany can do is build renewables now. 19 GW is an ambitious target, but Germany can do it. History shows us that Germany has been able to achieve high levels of renewable buildout in previous years. It must now reach those levels consistently.

“Creating a clear plan which sets out the steps to net zero is essential. Renewable energy is inherently intermittent, so flexible energy capacity will play a vital role. While batteries provide effective short-term flexibility, gas is currently the only practical long-term option. If Germany is to unlock the greatest benefits from decarbonisation, it must have a clear plan to integrate sustainable fuel. From 2030, all new thermal capacity must run solely on hydrogen.”

Analysis of the last decade demonstrates that the rapid expansion of renewable energy is possible, and that renewables overtook coal and nuclear in generation. Previously, Germany has built large amounts of renewable capacity, including 8GW of solar PV in 2010 and 2011, 5.3 GW of onshore wind in 2017, and 2.5 GW of offshore wind in 2015.

The significant reductions in the cost of electricity demonstrated in the modelling are driven by the fact that renewables are far cheaper to run than coal or gas plants, even as coal still provides about a third of electricity in Germany. The initial capital investment is far outweighed by the ongoing operational expense of fossil fuel-based power.

As well as reducing emissions and costs, Germany’s rapid path to net-zero can also unlock a series of additional benefits. If coal is phased out by 2030 but capacity is not replaced by high levels of renewable energy, Germany risks becoming a significant energy importer, peaking at 162 TWh in 2035. The accelerated pathway would reduce imports by a third.

Likewise, more renewable energy will help to electrify district heating, meaning Germany can move away from carbon-intensive fuels sooner. If Germany follows the accelerated path, 57% of Germany’s heating could be electrified in 2045, compared to 10% under the slower plan.

Jan Andersson concluded: “The opportunities on offer are vast. Germany can provide the blueprint for net zero and galvanise an entire continent. Now is the time for the new government to seize the initiative.”
