Solar CEOs gather for conference and exposition

Ontario IESO COVID-19 Control Room Measures detail how essential operators safeguard the electricity grid with split shifts, backup control centres, real-time balancing, deep cleaning, social distancing, and shelter-in-place readiness to maintain reliable power.

Key Points

Measures that protect essential grid operators with split shifts, backup sites, and hygiene to keep power reliable.

✅ Split teams across primary and backup control centres

✅ 12-hour shifts with remote handoffs and deep cleaning

✅ Real-time grid modeling to balance demand and supply

A group of personnel key to keeping Ontario's electricity system functioning may end up locked down in their control centres due to the COVID-19 crisis, according to the head of the province's power operator.

But that has so far proven unnecessary with a change-up in routine, Independent Electricity System Operator CEO Peter Gregg said.

While about 90 per cent of staff were sent to work from home on March 13, another 48 control-room operators deemed essential are still going into work, Gregg said in an interview.

"We identified a smaller cohort of critical operations room staff that need to go in to operate the system out of our control centres," Gregg said. "My biggest concern is to maintain their health, their safety as we rely on them to do this critical work."

Some of the operators manage power demand and supply in real time as Ontario electricity demand shifts, by calling for more or less generation and keeping an eye on the distribution grid, which also allows power to flow to and from Ontario's neighbours. Others do scenario planning and modelling to prepare for changes.

The essential operators have been split into eight teams of six each working 12-hour shifts. The day crew works out of a control centre near Toronto and the night shift out of a backup centre in the city's west end, Gregg said.

"That means that we're not having physical hand-off between control room operators on shift change -- we can do it remotely -- and it also allows us to do deep cleansing," Gregg said. "We're fortunate that the way the room is set up allows us to practice good social distancing."

Should it become necessary, he said, bed, food and other on-site arrangements have been made to allow the operators to stay at their workplaces as a similar agency in New York has done.

"If we do need to shelter these critical employees in place, we've got the ability to do so."

IESO is responsible for ensuring a balance between supply and demand for electricity across the province. Because power cannot be stored, the IESO ensures generators produce enough power to meet peak demand while making sure they don't produce too much.

"You're seeing, obviously, commercial demand drop, some industrial demand drop," Gregg said. "But you're also seeing a shift in the demand curve as well, where normally you have people heading off to work and so residential demand would go down. But obviously with them staying home, you're seeing an increase in residential electricity use across the province."

Some utilities have indicated no cuts to peak rates for self-isolating customers, with Hydro One peak pricing remaining in place for now.

IESO also runs and settles the wholesale electricity markets. Market prices are set based on accepted offers to supply electricity, while programs supporting stable electricity pricing for industrial and commercial users can affect costs against forecast demand.

With the pandemic forcing many businesses to close and people to stay home, and provincial electricity relief for families and small businesses in place, typical power needs fallen about seven per cent at a time of year that would normally see demand soften anyway. It remains to be seen whether, and how much, power needs shift further amid stringent isolation measures and the ongoing economic impact of the outbreak.

Gregg said the operator is constantly modeling different possibilities.

"What we do normally is prepare for all of these sort of emergency scenarios, as reflected in the U.S. grid response coverage, and test and drill for these," he said. "What we're experiencing over the last few weeks is that those drills come in handy because they help us prepare for when the real-time situation actually happens."

Electric Field-Induced Glass Softening reveals a Joule heating anomaly in silicate glass, where anode-side nanoscale alkali depletion drives ionic conduction, localized thermal runaway, melting, and evaporation, challenging homogeneity assumptions and refining materials processing models.

Key Points

An effect where electric fields lower glass softening temperature via nanoscale ionic migration and structural change.

✅ Anode-side alkali depletion creates extreme, localized heating

✅ Thermal runaway melts glass near the anode despite uniform bulk

✅ Findings refine Joule heating models and enable new glass processing

A team of scientists working with electrical currents and silicate glass have been left gobsmacked after the glass appeared to defy a basic physical law, in a field that also explores electricity-from-air devices for novel energy harvesting.

If you pass an electrical current through a material, the way that current generates heat can be described by Joule's first law. It's been observed time and time again, with the temperature always evenly distributed when the material is homogeneous (or uniform).

But not in this recent experiment. A section - and only a section - of silicate glass became so hot that it melted, and even evaporated. Moreover, it did so at a much lower temperature than the boiling point of the material.

The boiling point of pure silicate glass is 2,230 degrees Celsius (4,046 degrees Fahrenheit). The hottest temperature the researchers recorded in a homogeneous piece of silicate glass during the experiment was 1,868.7 degrees Celsius.

Say whaaaat.

"The calculations did not add up to explain what we were seeing as simply standard Joule heating," said engineer and materials scientist Himanshu Jain of Lehigh University.

"Even under very moderate conditions, we observed fumes of glass that would require thousands of degrees higher temperature than Joule's law could predict!"

Jain and his colleagues from materials science company Corning Incorporated were investigating a phenomenon they had described in a previous paper. In 2015, they reported that an electric field could reduce the temperature at which glass softens, by as much as a few hundred degrees, a line of inquiry that parallels work on low-cost heat-to-electricity materials in energy research. They called this "electric field-induced softening."

It was certainly a peculiar phenomenon, so they set up another experiment. They put pieces of glass in a furnace, and applied 100 to 200 volts in the form of both alternating and direct currents.

Next, a thin wisp of vapour emanated from the spot where the anode conveying the current contacted the glass.

"In our experiments, the glass became more than a thousand degrees Celsius hotter near the positive side than in the rest of the glass, which was very surprising considering that the glass was totally homogeneous to begin with," Jain said.

This seems to fly in the face of Joule's first law, so the team investigated more closely - and found that the glass wasn't remaining as homogeneous as it started out. The electric field changed the chemistry and the structure of the glass on nanoscale, in just a small section close to the anode.

This region heats faster than the rest of the glass, to the point of becoming a thermal runaway - where an increase in temperature further increases temperature in a blistering feedback loop.

As it turned out, that spot of structural change and dramatic heat resulted in a small area of glass reaching melting point while the rest of the material remained solid.

"Unlike electronically conducting metals and semiconductors, with time the heating of ionically conducting glass becomes extremely inhomogeneous with the formation of a nanoscale alkali-depletion region, such that the glass melts near the anode, even evaporates, while remaining solid elsewhere," the researchers wrote in their paper.

In other words, the material wasn't homogeneous any more, which means the glass heating experiment doesn't exactly change how we apply Joule's first law.

But it's an exciting result, since until now we didn't know a material could actually lose its homogeneity with the application of an electrical current, with possible implications for thin-film heat harvesters in electronics. (The thing is, no one had tried electrically heating glass to these extreme temperatures before.)

So the physical laws of the Universe are still okay, as a piece of glass hasn't broken them. But Joule's first law may need a bit of tweaking to take this effect into account, a reminder that unconventional energy concepts like nighttime solar cells also challenge our intuitions.

And, of course, it's another piece of understanding that could help us in other ways too, including advances in thermoelectric materials that turn waste heat into electricity.

"Besides demonstrating the need to qualify Joule's law," Jain said, "the results are critical to developing new technology for the fabrication and manufacturing of glass and ceramic materials."

The research has been published in Scientific Reports.

Global Decarbonization Strategies align renewable energy, electrification, clean air policies, IMO sulfur cap, LNG fuels, and the EU 2050 roadmap to cut carbon intensity and meet Paris Agreement targets via EVs and efficiency.

Key Points

Frameworks that cut emissions via renewables, EVs, efficiency, cleaner marine fuels, and EU policy roadmaps.

✅ Renewables scale as wind and solar outcompete new coal and gas.

✅ Electrification of transport grows as EV costs fall and charging expands.

✅ IMO 2020 sulfur cap and LNG shift cut shipping emissions and particulates.

Are we doing enough to save the planet? Silly question. The latest prognosis from the United Nations’ Intergovernmental Panel on Climate Change made for gloomy reading. Fundamental to the Paris Agreement is the target of keeping global average temperatures from rising beyond 2°C. The UN argues that radical measures are needed, and investment incentives for clean electricity are seen as critical by many leaders to accelerate progress to meet that target.

Renewable power and electrification of transport are the pillars of decarbonization. It’s well underway in renewables - the collapse in costs make wind and solar generation competitive with new build coal and gas.

Renewables’ share of the global power market will triple by 2040 from its current level of 6% according to our forecasts.

The consumption side is slower, awaiting technological breakthrough and informed by efforts in countries such as New Zealand’s electricity transition to replace fossil fuels with electricity. The lower battery costs needed for electric vehicles (EVs) to compete head on and displace internal combustion engine (ICE)  cars are some years away. These forces only start to have a significant impact on global carbon intensity in the 2030s. Our forecasts fall well short of the 2°C target, as does the IEA’s base case scenario.

Yet we can’t just wait for new technology to come to the rescue. There are encouraging signs that society sees the need to deal with a deteriorating environment. Three areas of focus came out in discussion during Wood Mackenzie’s London Energy Forum - unrelated, different in scope and scale, each pointing the way forward.

First, clean air in cities.  China has shown how to clean up a local environment quickly. The government reacted to poor air quality in Beijing and other major cities by closing older coal power plants and forcing energy intensive industry and the residential sector to shift away from coal. The country’s return on investment will include a substantial future health care dividend.

European cities are introducing restrictions on diesel cars to improve air quality. London’s 2017 “toxicity charge” is a precursor of an Ultra-Low Emission Zone in 2019, and aligns with UK net-zero policy changes that affect transport planning, to be extended across much of the city by 2020. Paris wants to ban diesel cars from the city centre by 2025 and ICE vehicles by 2030. Barcelona, Madrid, Hamburg and Stuttgart are hatching similar plans.

College Promise In California: Community-Wide Efforts To Support Student Success

Second, desulphurisation of global shipping. High sulphur fuel oil (HSFO) meets around 3.5 million barrels per day (b/d) of the total marine market of 5 million b/d. A maximum of 3.5% sulphur content is allowed currently. The International Maritime Organisation (IMO) implements a 0.5% limit on all shipping in 2020, dramatically reducing the release of sulphur oxides into the atmosphere.

Some ships will switch to very low sulphur fuel oil, of which only around 1.4 million b/d will be available in 2020. Others will have to choose between investing in scrubbers or buying premium-priced low sulphur marine gas oil.

Longer-term, lower carbon-intensity gas is a winner as liquefied natural gas becomes fuel of choice for many newbuilds. Marine LNG demand climbs from near zero to 50 million tonnes per annum (tpa) by 2040 on our forecasts, behind only China, India and Japan as a demand centre. LNG will displace over 1 million b/d of oil demand in shipping by 2040.

Third, Europe’s radical decarbonisation plans. Already in the vanguard of emissions reductions policy, the European Commission is proposing to reduce carbon emissions for new cars and vans by 30% by 2030 versus 2020. The targets come with incentives for car manufacturers linked to the uptake of EVs.

The 2050 roadmap, presently at the concept stage, envisages a far more demanding regime, with EU electricity plans for 2050 implying a much larger power system. The mooted 80% reduction in emissions compared with 1990 will embrace all sectors. Power and transport are already moving in this direction, but the legacy fuel mix in many other sectors will be disrupted, too.

Near zero-energy buildings and homes might be possible with energy efficiency improvements, renewables and heat pumps. Electrification, recycling and bioenergy could reduce fossil fuel use in energy intensive sectors like steel and aluminium, and Europe’s oil majors going electric illustrates how incumbents are adapting. Some sectors will cite the risk decarbonisation poses to Europe’s global competitiveness. If change is to come, industry will need to build new partnerships with society to meet these targets.

The 2050 roadmap signals the ambition and will be game changing for Europe if it is adopted. It would provide a template for a global roll out that would go a long way toward meeting UN’s concerns.

Ontario Nuclear Refurbishment Economic Impact powers growth as Bruce Power's MCR and OPG's Darlington unit 2 refurbishment drive jobs, supply-chain spending, medical isotopes, clean baseload power, and lower GHG emissions across Ontario and Canada.

Key Points

It is the measured gains from Bruce Power's MCR and OPG's Darlington refurbishment in jobs, taxes, and clean energy.

✅ CAD7.6B-10.6B impact in Ontario; CAD8.1B-11.6B nationwide.

✅ Supports 60% nuclear supply, jobs, and medical isotopes.

✅ MCR and Darlington cut GHGs, drive innovation and supply chains.

The 13-year Major Component Replacement (MCR) project being undertaken as part of Bruce Power's life-extension programme, which officially began with a reactor taken offline earlier this year, will inject billions of dollars into Ontario's economy, a new report has found. Meanwhile, the major project to refurbish Darlington unit 2 remains on track for completion in 2020, Ontario Power Generation (OPG) has announced.

The Ontario Chamber of Commerce (OCC) said its report, Major Component Replacement Project Economic Impact Analysis, outlines an impartial assessment of the MCR programme and related manufacturing contracts across the supply chain. The report was commissioned by Bruce Power.

"Our analysis shows that Bruce Power's MCR project is a fundamental contributor to the Ontario economy. More broadly, the life-extension of the Bruce Power facility will provide quality jobs for Ontarians, produce a stable supply of medical isotopes for the world's healthcare system, and deliver economic benefit through direct and indirect spending," OCC President and CEO Rocco Rossi said."As Ontario's energy demand grows, nuclear truly is the best option to meet those demands with reduced GHG [greenhouse gas] emissions. The Bruce Power MCR Project will not only drive economic growth in the region, it will position Ontario as a global leader in nuclear innovation and expertise."

According to the OCC's economic analysis, the MCR's economic impact on Ontario is estimated to be between CAD7.6 billion (USD5.6 billion) and CAD10.6 billion. Nationally, its economic impact is estimated to be between CAD8.1 billion and CAD11.6 billion. It estimates that the federal government will receive CAD144 million in excise tax and CAD1.2 billion in income tax, while the provincial government will receive CAD300 million and CAD437 million. Ontario’s municipal governments are estimated to receive a collective CAD192 million in tax.

The nuclear industry currently provides 60% of Ontario’s daily energy supply needs, with Pickering life extension plans bolstering system reliability, and is made up of over 200 companies and more than 60,000 jobs across a diversity of sectors such as operations, manufacturing, skilled trades, healthcare, and research and innovation, the report notes.

Greg Rickford, Ontario's minister of Energy, Northern Development and Mines, and minister of Indigenous Affairs, said continued use of the Bruce generating station which recently set an operating record would create jobs and advance Ontario’s nuclear industrial sector. "It is great to see projects like the MCR that help make Ontario the best place to invest, do business and find a job," he said.

The MCR is part of Bruce Power's overall life-extension programme, which started in January 2016. Bruce 6 will be the first of the six Candu units to undergo an MCR which will take 46 months to complete and give the unit a further 30-35 years of operational life. The total cost of refurbishing Bruce units 3-8 is estimated at about CAD8 billion, in addition to CAD5 billion on other activities under the life-extension programme, which is scheduled for completion by 2053.

Darlington milestones

OPG's long-term refurbishment programme at Darlington, alongside SMR plans for the site announced by the province, began with unit 2 in 2016 after years of detailed planning and preparation. Reassembly of the reactor, which was disassembled last year, is scheduled for completion this spring, and the unit 2 refurbishment project remains on track for completion in early 2020. At the same time, final preparations are under way for the start of the refurbishment of unit 3.

"We've entered a critical phase on the project," Senior Vice President of Nuclear Refurbishment Mike Allen said. "OPG and our project partners continue to work as an integrated team to meet our commitments on Unit 2 and our other three reactors at Darlington Nuclear Generating Station."

A 350-tonne generator stator manufactured by GE in Poland is currently in transit to Canada, where it will be installed in Darlington 3's turbine hall as the province also breaks ground on its first SMR this year.

The 10-year Darlington refurbishment is due to be completed in 2026, while the province plans to refurbish Pickering B to extend output beyond that date.

Texas Electricity Market Bailout proposes securitization bonds and ERCOT-backed fees after Winter Storm Uri, spreading costs via ratepayer charges on power bills to stabilize generators, co-ops, and retailers and avert bankruptcies and investor flight.

Key Points

State plan to securitize storm debts via ERCOT fees, adding bill charges to stabilize Texas power firms.

✅ Securitization bonds finance unpaid ancillary services and energy costs

✅ ERCOT fee spreads Winter Storm Uri debts across ratepayers statewide

✅ Aims to prevent bankruptcies, preserve grid reliability, reassure investors

An approximately $2.5 billion plan to bail out Texas’ distressed electricity market from the financial crisis caused by Winter Storm Uri in February has been approved by the Texas House.

The legislation would impose a fee — likely for the next decade or longer — on electricity companies, which would then get passed on to residential and business customers in their power bills, even as some utilities waived certain fees earlier in the crisis.

House lawmakers sent House Bill 4492 to the Senate on Thursday after a 129-15 vote. A similar bill is advancing in the Senate.

Some of the state’s electricity providers and generators are financially underwater in the aftermath of the February power outages, which left millions without power and killed more than 100 people. Electricity companies had to buy whatever power was available at the maximum rate allowed by Texas regulations — $9,000 per megawatt hour — during the week of the storm (the average price for power in 2020 was $22 per megawatt hour). Natural gas fuel prices also spiked more than 700% during the storm.

Several companies are nearing default on their bills to the Electric Reliability Council of Texas, which manages the Texas power grid that covers most of the state and facilitates financial transactions in it.

Rural electric cooperatives were especially hard hit; Brazos Electric Power Cooperative, which supplies electricity to 1.5 million customers, filed for bankruptcy citing a $1.8 billion debt to ERCOT.

State Rep. Chris Paddie, R-Marshall, the bill’s author, said a second bailout bill will be necessary during the current legislative session for severely distressed electric cooperatives.

“This is a financial crisis, and it’s a big one,” James Schaefer, a senior managing director at Guggenheim Partners, an investment bank, told lawmakers at a House State Affairs Committee hearing in early April. He warned that more bankruptcies would cause higher costs to customers and hurt the state’s image in the eyes of investors.

“You’ve got to free the system,” Schaefer said. “It’s horrible that a bunch of folks have to pay, but it’s a system-wide failure. If you let a bunch of folks crash, it’s not a good look for your state.”

If approved by the Senate and Gov. Greg Abbott, a newly-created Texas Electric Securitization Corp. would use the money raised from the fees for bonds to help pay the companies’ debts, including costs for ancillary services, a financial product that helps ensure power is continuously generated and improve electricity reliability across the grid.

Paddie told his colleagues Wednesday that he could not yet estimate how long the new fee would be imposed, but during committee hearings lawmakers estimated it’s likely to be at least a decade. Several other bills to spread out the costs of the winter storm and consider market reforms are also moving through the Legislature.

ERCOT’s independent market monitor recommended in March that energy sold during that period be repriced at a lower rate, which would have allowed ERCOT to claw back about $4.2 billion in payments to power generators, but the Public Utility Commission declined to do so, even as a court ruling on plant obligations in emergencies drew scrutiny among market participants.

Instead, lawmakers are pushing for bailouts that several energy experts have said is needed, both to ensure distressed companies don’t pass enormous costs on to their customers and to prevent electricity investors and companies from leaving the state if it’s viewed as too risky to continue doing business.

Becky Klein, an energy consultant in Austin and former chair of the Public Utility Commission who played a key role in de-regulating Texas’ electricity market two decades ago, said during a retail electricity panel hosted by Integrate that legislation is necessary to provide “some kind of backstop during a crazy market crisis like this to show the financial market that we’re willing to provide some relief.”

Still, some lawmakers are concerned with how they will win public support, including potential voter-approved funding measures, for bills to bail out the state’s electricity market.

“I have to go back to Laredo and say, ‘I know you didn’t have electricity for several days, but now I’m going to make you pay a little more for the next 20 years,’” state Rep. Richard Peña Raymond, D-Laredo, said during an early April discussion on the plan in the House State Affairs Committee. He said he voted for the bill because it’s in the best interest of the state.

Paddie, during the same committee hearing, acknowledged that “none of us want to increase fees or taxes.” However, he said, “We have to deal with the reality set before us.”

UK Energy Price Cap drives household electricity bills and gas prices, as Ofgem adjusts unit rates amid natural gas shortages, Russia-Ukraine disruptions, inflation, recession risks, and limited storage; government support offers only short-term relief.

Key Points

The UK Energy Price Cap limits per-unit gas and electricity charges set by suppliers and adjusted by Ofgem.

✅ Reflects wholesale natural gas costs; varies quarterly

✅ Protects consumers from sudden electricity and heating bill spikes

✅ Does not cap total annual spend; usage still determines bills

The government organization that controls the cost of energy in Great Britain recently increased what is known as a price cap on household energy bills. The price cap is the highest amount that gas suppliers can charge for a unit of energy.

The new, higher cost has people concerned that they may not be able to pay for their gas and electricity this winter. Some might pay as much as $4,188 for energy next year. Earlier this year, the price cap was at $2,320, and a 16% decrease in bills is anticipated in April.

Why such a change?

Oil and gas prices around the world have been increasing since 2021 as economies started up again after the coronavirus pandemic. More business activities required more fuel.

Then, Russia invaded Ukraine in late February, creating a new energy crisis. Russia limited the amount of natural gas it sent to European countries that needed it to power factories, produce electricity and keep homes warm.

Some energy companies are charging more because they are worried that Russia might completely stop sending gas to European countries. And in Britain, prices are up because the country does not produce much gas or have a good way to store it. As a result, Britain must purchase gas often in a market where prices are high, and ministers have discussed ending the gas-electricity price link to ease bills.

Citibank, a U.S. financial company, believes the higher energy prices will cause inflation in Britain to reach 18 percent in 2023, while EU energy inflation has also been driven higher by energy costs this year. And the Bank of England says an economic slowdown known as a recession will start later this year.

Public health and private aid organizations worry that high energy prices will cause a “catastrophe” as Britons choose between keeping their homes warm and eating enough food.

What can government do?

As prices rise, the British government plans to give people between $450 and $1,400 to help pay for energy costs, while some British MPs push to further restrict the price charged for gas and electricity. But the help is seen by many as not enough.

If the government approves more money for fuel, it will probably not come until September, as the energy security bill moves toward becoming law. That is the time the Conservative Party will select a new leader to replace Prime Minister Boris Johnson.

The Labour Party says the government should increase the amount it provides for people to pay for fuel by raising taxes on energy companies. However, the two politicians who are trying to become the next Prime Minister do not seem to support that idea.

Giovanna Speciale leads an organization called the Southeast London Community Energy group. It helps people pay their bills. She said the money will help but it is only a short-term solution to a bigger problem with Britain’s energy system. Because the system is privately run, she said, “there’s very little that the government can do to intervene in this.”

Other European countries are seeing higher energy costs, but not as high, and at the EU level, gas price cap strategies have been outlined to tackle volatility. In France, gas prices are capped at 2021 levels. In Germany, prices are up by 38 percent since last year. However, the government is reducing some taxes, which will make it easier for the average person to buy gas. In Italy, prices are going up, but the government recently approved over $8 billion to help people pay their energy bills.
