Zero emission cars wonÂ’t be cheap

Calgary Winter Energy Usage Surge highlights soaring electricity demand, added megawatt-hours, and grid reliability challenges driven by extreme cold, heating loads, and climate change, with summer air conditioning also shifting seasonal peaks.

Key Points

A spike in Calgary's power use from extreme cold, adding 22k MWh and testing reliability as heating demand rises.

✅ +22,000 MWh vs Feb 2018 amid fourth-coldest February

✅ Heating loads spike; summer A/C now drives peak demand

✅ Grid reliability monitored; more solar and green resources ahead

February was so cold in Calgary that the city used enough extra energy to power 3,400 homes for a whole year, echoing record-breaking demand in B.C. in 2021 during severe cold.

Enmax Power Corporation, the primary electricity utility in the city, says the city 's energy consumption was up 22,000 megawatt hours last month compared with Februray 2018.

"We've seen through this cold period our system has held up very well. It's been very reliable," Enmax vice-president Andre van Dijk told the Calgary Eyeopener on Friday. "You know, in the absence of a windstorm combined with cold temperatures and that sort of thing, the system has actually held up pretty well."

The past month was the fourth coldest in Calgary's history, and similar conditions have pushed all-time high demand in B.C. in recent years across the West. The average temperature for last month was –18.1 C. The long-term average for February is –5.4 C.

Watching use, predicting issues

The electricity company monitors demand and load on a daily basis, always trying to predict issues before they happen, van Dijk said, and utilities have introduced winter payment plans to help customers manage bills during prolonged cold.

One of the issues they're watching is climate change, and how extreme temperatures and weather affect both the grid's reliability, as seen when Quebec shattered consumption records during cold snaps, and the public's energy use.

The colder it gets, the higher you turn up the heat. The hotter it is, the more you use air conditioning.

He also noted that using fuels then contributes to climate change, creating a cycle.

​"We are seeing variations in temperature and we've seen large weather events across the continent, across the world, in fact, that impact electrical systems, whether that's flooding, as we've experienced here, or high winds, tornadoes," van Dijk said.

"Climate change and changing weather patterns have definitely had had an impact on us as an electrical industry."

In 2012, he said, Calgary switched from using the most power during winter to using the most during summer, in large part due to air conditioning, he said.

"Temperature is a strong influencer of energy consumption and of our demand," van Dijk said.

Christmas tree lights have also become primarily LED, van Dijk said, which cuts down on a big energy draw in the winter.

He said he expects more solar and other green resources will be added into the electrical system in the future to mitigate how much the increasingly levels of energy use impact climate change, and to help moderate electricity costs in Alberta over time.

Barakah Unit 1 100 Percent Power signals the APR-1400 reactor delivering 1400MW of clean baseload electricity to the UAE grid, advancing decarbonisation, reliability, and Power Ascension Testing milestones ahead of commercial operations in early 2021.

Key Points

The milestone where Unit 1 reaches full 1400MW output to the UAE grid, providing clean, reliable baseload electricity.

✅ Delivers 1400MW from a single generator to the UAE grid

✅ Enables clean, reliable baseload power with zero operational emissions

✅ Completes key Power Ascension Testing before commercial operations

The Emirates Nuclear Energy Corporation, ENEC, has announced that its operating and maintenance subsidiary, Nawah Energy Company, Nawah, has successfully achieved 100% of the rated reactor power capacity for Unit 1 of the Barakah Nuclear Energy Plant. This major milestone, seen as a crucial step in Abu Dhabi towards completion, brings the Barakah plant one step closer to commencing commercial operations, scheduled in early 2021.

100% power means that Unit 1 is generating 1400MW of electricity from a single generator connected to the UAE grid for distribution. This milestone makes the Unit 1 generator the largest single source of electricity in the UAE.

The Barakah Nuclear Energy Plant is the largest source of clean baseload electricity in the country, capable of providing constant and reliable power in a sustainable manner around the clock. This significant achievement accelerates the decarbonisation of the UAE power sector, while also supporting the diversification of the Nation’s energy portfolio as it transitions to cleaner electricity sources, similar to the steady development in China of nuclear energy programs now underway.

The accomplishment follows shortly after the UAE’s celebration of its 49th National Day, providing a strong example of the country’s progress as it continues to advance towards a sustainable, clean, secure and prosperous future, having made the UAE the first Arab nation to open a nuclear plant as it charts this path. As the Nation looks towards the next 50 years of achievements, the Barakah plant will generate up to 25 percent of the country’s electricity, while also acting as a catalyst of the clean carbon future of the Nation.

Mohamed Ibrahim Al Hammadi, Chief Executive Officer of ENEC said: "We are proud to deliver on our commitment to power the growth of the UAE with safe, clean and abundant electricity. Unit 1 marks a new era for the power sector and the future of the clean carbon economy of the Nation, with the largest source of electricity now being generated without any emissions. I am proud of our talented UAE Nationals, working alongside international experts who are working to deliver this clean electricity to the Nation, in line with the highest standards of safety, security and quality." Nawah is responsible for operating Unit 1 and has been responsible for safely and steadily raising the power levels since it commenced the start-up process in July, and connection to the grid in August.

Achieving 100% power is one of the final steps of the Power Ascension Testing (PAT) phase of the start-up process for Unit 1. Nawah’s highly skilled and certified nuclear operators will carry out a series of tests before the reactor is safely shut down in preparation for the Check Outage. During this period, the Unit 1 systems will be carefully examined, and any planned or corrective maintenance will be performed to maintain its safety, reliability and efficiency prior to the commencement of commercial operations.

Ali Al Hammadi, Chief Executive Officer of Nawah, said: "This is a key achievement for the UAE, as we safely work through the start-up process for Unit 1 of the Barakah plant. Successfully reaching 100% of the rated power capacity in a safe and controlled manner, undertaken by our highly trained and certified nuclear operators, demonstrates our commitment to safe, secure and sustainable operations as we now advance towards our final maintenance activities and prepare for commercial operations in 2021." The Power Ascension Testing of Unit 1 is overseen by the independent national regulator – the Federal Authority for Nuclear Regulation (FANR), which has conducted 287 inspections since the start of Barakah’s development. These independent reviews have been conducted alongside more than 40 assessments and peer reviews by the International Atomic Energy Agency, IAEA, and World Association of Nuclear Operators, WANO, reflecting milestones at nuclear projects worldwide that benchmark safety and performance.

This is an important milestone for the commercial performance of the Barakah plant. Barakah One Company, ENEC’s subsidiary in charge of the financial and commercial activities of the Barakah project signed a Power Purchase Agreement, PPA, with the Emirates Water and Electricity Company, EWEC, in 2016 to purchase all of the electricity generated at the plant for the next 60 years. Electricity produced at Barakah feeds into the national grid in the same manner as other power plants, flowing to homes and business across the country.

This milestone has been safely achieved despite the challenges of COVID-19. Since the beginning of the global pandemic, ENEC, and subsidiaries Nawah and Barakah One Company, along with companies that form Team Korea, including Korea Hydro & Nuclear Power, with KHNP’s work in Bulgaria illustrating its global role, have worked closely together, in line with all national and local health authority guidelines, to ensure the highest standards for health and safety are maintained for those working on the project. ENEC and Nawah’s robust business continuity plans were activated, alongside comprehensive COVID-19 prevention and management measures, including access control, rigorous testing, and waste water sampling, to support health and wellbeing.

The Barakah Nuclear Energy Plant, located in the Al Dhafra region of the Emirate of Abu Dhabi, is one of the largest nuclear energy new build projects in the world, with four APR-1400 units. Construction of the plant began in 2012 and has progressed steadily ever since. Construction of Units 3 and 4 are in the final stages with 93 percent and 87 percent complete respectively, benefitting from the experience and lessons learned during the construction of Units 1 and 2, while the construction of the Barakah Plant as a whole is now more than 95 percent complete.

Once the four reactors are online, Barakah Plant will deliver clean, efficient and reliable electricity to the UAE grid for decades to come, providing around 25 percent of the country’s electricity and, as other nations like Bangladesh expand with IAEA assistance, reinforcing global decarbonisation efforts, preventing the release of up to 21 million tons of carbon emissions annually – the equivalent of removing 3.2 million cars off the roads each year.

Fukushima Hydrogen Energy System leverages a 10,000 kW H2 production hub for grid balancing, demand response, and renewable integration, delivering hydrogen supply across Tohoku while supporting storage, forecasting, and flexible power management.

Key Points

A 10,000 kW H2 project in Namie for grid balancing, renewable integration, and regional hydrogen supply.

✅ 10,000 kW H2 production hub in Namie, Fukushima

✅ Balances renewable-heavy grids via demand response

✅ Supported by NEDO; partners Toshiba, Tohoku Electric, Iwatani

Toshiba Corporation, Tohoku Electric Power Co. and Iwatani Corporation have announced they will construct and operate a large-scale hydrogen (H2) energy system in Japan, based on a 10,000 kilowat class H2 production facility, which reflects advances in PEM hydrogen R&D worldwide.

The system, which will be built in Namie-Cho, Fukushima, will use H2 to offset grid loads and deliver H2 to locations in Tohoku and beyond, while complementary approaches like power-to-gas storage in Europe demonstrate broader storage options, and will seek to demonstrate the advantages of H2 as a solution in grid balancing and as a H2 gas supply.

The product has won a positive evaluation from Japan’s New Energy and Industrial Technology Development Organisation (NEDO), and its continued support for the transition to the technical demonstration phase. The practical effectiveness of the large-scale system will be determined by verification testing in financial year 2020, even as interest grows in nuclear beyond electricity for complementary services.

The main objectives of the partners are to promote expanded use of renewable energy in the electricity grid, including UK offshore wind investment by Japanese utilities, in order to balance supply and demand and process load management; and to realise a new control system that optimises H2 production and supply with demand forecasting for H2.

Hiroyuki Ota, General Manager of Toshiba’s Energy Systems and Solutions Company, said, “Through this project, Toshiba will continue to provide comprehensive H2 solutions, encompassing all processes from the production to utilisation of hydrogen.”

Manager of Tohoku Electric Power Co., Ltd, Mitsuhiro Matsumoto, added, “We will study how to use H2 energy systems to stabilize electricity grids with the aim of increasing the use of renewable energy and contributing to Fukushima.”

Moriyuki Fujimoto, General Manager of Iwatani Corporation, commented, “Iwatani considers that this project will contribute to the early establishment of a H2 economy that draws on our experience in the transportation, storage and supply of industrial H2, and the construction and operation of H2stations.”

Japan’s Ministry of Economy, Trade and Industry’s ‘Long-term Energy Supply and Demand Outlook’ targets increasing the share of renewable energy in Japan’s overall power generation mix from 10.7% in 2013 to 22-24% by 2030. Since output from renewable energy sources is intermittent and fluctuates widely with the weather and season, grid management requires another compensatory power source, as highlighted by a near-blackout event in Japan. The large hydrogen energy system is expected to provide a solution for grids with a high penetration of renewables.

Medicine Hat Bitcoin Mining Facility drives massive electricity demand and energy use, leveraging natural gas and nearby wind power; Hut 8 touts economic growth, while critics cite carbon emissions, renewables integration, and climate impact.

Key Points

A Hut 8 project in Alberta that mines bitcoin at scale, consuming up to 60 MW and impacting energy and emissions.

✅ Consumes more than 60 MW, rivaling citywide electricity use

✅ Sited by natural gas plant; wind turbines nearby

✅ Economic gains vs. carbon emissions and climate risks

On the day of the grand opening of the largest bitcoin mining project in the country, the weather was partly cloudy and 15 C. On a Friday afternoon like this one, the new facility uses as much electricity as all of Medicine Hat, Alta., a city of more than 60,000 people and home to several large industrial plants.

The vast amount of electricity needed for bitcoin mining is why the city of Medicine Hat has championed the economic benefits of the project, while environmentalists say they are wary of the significant energy use.

Toronto-based Hut 8 has spent more than $100 million to develop the 4½-hectare site on the northern edge of the city. It has 56 shipping containers, each filled with 180 computer servers that digitally mine for bitcoin around the clock.

The company said it has already mined more than 3,300 bitcoins in Alberta, including at its much smaller site in Drumheller. On average, the Medicine Hat facility mines about 20 bitcoins per day. The value of bitcoin can fluctuate daily, but has sold recently for around $9,000.

The bitcoin mining facility is located right beside the city of Medicine Hat's new natural gas-fired power plant and four wind turbines are a short distance away. The bitcoin plant can consume more than 60 megawatts of power, more than 10 times more electricity used by any other facility in the city, according to the mayor.

That's why, in the event of a summer heat wave, the city has provisions in place to pull the plug on the electricity it provides to Hut 8, mirroring utility pauses on crypto loads seen elsewhere, so there won't be any blackouts for residents, according to the mayor.

Still, some say the bitcoin mining industry wastes far too much energy

"It's a huge magnitude when you talk about the carbon emissions," said Saeed Kaddoura, an analyst with the Pembina Institute, an environmental think-tank. "Moving forward, there needs to be some consideration on what the environmental impact of this is."

Medicine Hat owns its own natural gas and electricity generation and distribution businesses. The city leases the land to Hut 8 and the facility employs 40 full-time workers. Add up the economic benefits and the city of Medicine Hat will receive a significant financial boost from the new project, says Ted Clugston, the city's mayor.

Financial details of the city's deal with Hut 8 are not disclosed.

For more than a century, the city has attracted business by offering low-cost energy, and the mayor said this project is no different.

"They could have gone anywhere in the world and they chose Medicine Hat," said Clugston. "[Hut 8] is not here for renewable energy because it is not reliable. They need gas-fired generation and we have it in spades."

Environmental groups are concerned by the sheer amount of energy consumed by bitcoin mining, with some utilities warning they can't serve new energy-intensive customers right now, especially in places like Medicine Hat where most of the electricity is produced by fossil fuels.

The bitcoin system is designed, so only a limited number of the cryptocurrency can be mined everyday. Over time, as more miners compete for a decreasing number of available bitcoins, facilities will have to use more electricity compared to the amount of the cryptocurrency they collect.

"The way the bitcoin algorithm works is that it's designed to waste as much electricity as possible. And the more popular bitcoin becomes, the more electricity it wastes," said Keith Stewart, a spokesperson for Greenpeace.

Stewart questions whether natural gas should be used to produce a digital product.

"If you live in Alberta, you want to have heat and light, those types of things. I don't think bitcoin is a necessity of life for anyone," he said.

The CEO of Hut 8 completely disagrees, arguing the cryptocurrency is essential.  

"Bitcoin was created during the financial crisis. It has really served a purpose in terms of providing the opportunity for people who don't necessarily trust their government or their central banks," said Andrew Kiguel.

China Power Demand-Emissions Gap highlights surging grid demand outpacing renewables, with coal filling shortages despite record solar, wind, EV charging, and hydrogen growth, threatening decarbonization targets and net-zero pathways through 2030.

Key Points

China's power demand outpaces renewables, keeping coal dominant and raising emissions risk through the 2020s.

✅ Record solar and wind still lag fast grid demand growth

✅ Coal fills gaps as EV charging and hydrogen loads rise

✅ Forecasts diverge: CEC bullish vs IEA, BNEF conservative

Here’s a new obstacle that could prevent the world finally turning the corner on climate change: Imagine that over the coming decade a whole new economy the size of Russia were to pop up out of nowhere. With the world’s fourth-largest electricity sector and largest burden of power plant emissions after China, the U.S. and India, this new economy on its own would be enough to throw out efforts to halt global warming — especially if it keeps on growing through the 2030s.

That’s the risk inherent in China’s seemingly insatiable appetite for grid power, as surging electricity demand is putting systems under strain worldwide.

From the cracking pace of renewable build-out last year, you might think the country had broken the back of its carbon addiction. A record 55 gigawatts of solar power and 48 gigawatts of wind were connected — comparable to installing the generation capacity of Mexico in less than 12 months. This year will see an even faster pace, with 93 GW of solar and 50 GW of wind added, according to a report last week from the China Electricity Council, an industry association.

That progress could in theory see the country’s power sector emissions peak within months, rather than the late-2020s date the government has hinted at. Combined with a smaller quantity of hydro and nuclear, low-emissions sources will probably add about 310 terawatt-hours to zero-carbon generation this year. That 3.8% increase would be sufficient to power the U.K.

Countries that have reached China’s levels of per-capita electricity consumption (already on a par with most of Europe) typically see growth rates at less than half that level, even as global power demand has surged past pre-pandemic levels in recent years. Grid supply could grow at a faster pace than Brazil, Iran, South Korea or Thailand managed over the past decade without adding a ton of additional carbon to the atmosphere.

There’s a problem with that picture, however. If electricity demand grows at an even more headlong pace, there simply won’t be enough renewables to supply the grid. Fossil fuels, overwhelmingly coal, will fill the gap, a reminder of the iron law of climate dynamics in energy transitions.

Such an outcome looks distinctly possible. Electricity consumption in 2021 grew at an extraordinary rate of 10%, and will increase again by between 5% and 6% this year, according to the CEC. That suggests the country is on pace to match the CEC’s forecasts of bullish grid demand over the coming decade, with generation hitting 11,300 terawatt-hours in 2030. External analysts, such as the International Energy Agency and BloombergNEF, envisage a more modest growth to around 10,000 TWh. 

The difference between those two outlooks is vast — equivalent to all the electricity produced by Russia or Japan. If the CEC is right and the IEA and BloombergNEF are wrong, even the furious rate of renewable installations we’re seeing now won’t be enough to rein in China’s power-sector emissions.

Who’s correct? On one hand, it’s fair to say that power planners usually err on the side of overestimation. If your forecast for electricity demand is too high, state-owned generators will be less profitable than they otherwise would have been — but if it’s too low, you’ll see power cuts and shutdowns like China witnessed last autumn, with resulting power woes affecting supply chains beyond its borders.

On the other hand, the decarbonization of China’s economy itself should drive electricity demand well above what we’ve seen in the past, with some projections such as electricity meeting 60% of energy use by 2060 pointing to a profound shift. Some 3.3 million electric vehicles were sold in 2021 and BloombergNEF estimates a further 5.7 million will be bought in 2022. Every million EVs will likely add in the region of 2 TWh of load to the grid. Those sums quickly mounts up in a country where electric drivetrains are taking over a market that shifts more than 25 million new cars a year.

Decarbonizing industry, a key element on China’s road to zero emissions, could also change the picture. The IEA sees the country building 25 GW of electolysers to produce hydrogen by 2030, enough to consume some 200 TWh on their own if run close to full-time.

That’s still not enough to justify the scale of demand being forecast, though. China is already one of the least efficient countries in the world when it comes to translating energy into economic growth, and despite official pressure on the most wasteful, so called “dual-high” industries such as steel, oil refining, glass and cement, its targets for more thrifty energy usage remain pedestrian.

The countries that have decarbonized fastest are those, such as Germany, the U.K and the U.S., where Americans are using less electricity, that have seen power demand plateau or even decline, giving new renewable power a chance to swap out fossil-fired generators without chasing an ever-increasing burden on the grid. China’s inability to do this as its population peaks and energy consumption hits developed-country levels isn’t a sign of strength.

Instead, it’s a sign of a country that’s chronically unable to make the transition away from polluting heavy industry and toward the common prosperity and ecological civilization that its president keeps promising. Until China reins in that credit-fueled development model, the risks to its economy and the global climate will only increase.

Illinois NextGrid redefines utility, customer, and provider roles with grid modernization, DER valuation, upfront rebates, net metering reform, and non-wires alternatives, leveraging rooftop solar, batteries, and performance signals to enhance reliability and efficiency.

Key Points

Illinois NextGrid is an ICC roadmap to value DER and modernize the grid with rebates and non-wires solutions.

✅ Upfront Value-of-DER rebates reward location, time, and performance.

✅ Locational DER reduce peak demand and defer wires and substations.

✅ Encourages non-wires alternatives and data-driven utility planning.

How does the electric utility fit in to a rapidly-evolving energy system? That’s what the Illinois Commerce Commission is trying to determine with its new effort, "NextGrid". Together, we’re rethinking the roles of the utility, the customer, and energy solution providers in a 21st-century digital grid landscape.

In some ways, NextGrid will follow in the footsteps of New York’s innovative Reforming the Energy Vision process, a multi-year effort to re-examine how electric utilities and customers interact. A new approach is essential to accelerating the adoption of clean energy technologies and building a smarter electricity infrastructure in the state.

Like REV, NextGrid is gaining national attention for stakeholder-driven processes to reveal new ways to value distributed energy resources (DER), like rooftop solar and batteries. New York and Illinois’ efforts also seek alternatives, such as virtual power plants, to simply building more and more wires, poles, and power plants to meet the energy needs of tomorrow.

Yet, Illinois is may go a few steps beyond New York, creating a comprehensive framework for utilities to measure how DER are making the grid smarter and more efficient. Here is what we know will happen so far.

On Wednesday, April 5, at the second annual Grid Modernization Forum in Chicago, I’ll be discussing why these provisions could change the future of our energy system, including insights on grid modernization affordability for stakeholders.

Value of distributed energy

The Illinois Commerce Commission’s NextGrid plans grew out of the recently-passed future energy jobs act, a landmark piece of climate and energy policy that was widely heralded as a bipartisan oddity in the age of Trump. The Future Energy Jobs Act will provide significant new investments in renewables and energy efficiency over the next 13 years, redefine the role and value of rooftop solar and batteries on the grid, and lead to significant greenhouse gas emission reductions.

NextGrid will likely start laying the groundwork for valuing distributed energy resources (DER) as envisioned by the Future Energy Jobs Act, which introduces the concept of a new rebate. Illinois currently has a net metering policy, which lets people with solar panels sell their unused solar energy back to the grid to offset their electric bill. Yet the net metering policy had an arbitrary “cap,” or a certain level after which homes and businesses adding solar panels would no longer be able to benefit from net metering.

Although Illinois is still a few years away from meeting that previous “cap,” when it does hit that level, the new policy will ensure additional DER will still be rewarded. Under the new plan, the Value-of-DER rebate will replace net metering on the distribution portion of a customer’s bill (the charge for delivering electricity from the local substation to your house) with an upfront payment, which credits the customer for the value their solar provides to the local grid over the system’s life. Net metering for the energy supply portion of the bill would remain – i.e. homes and businesses would still be able to offset a significant portion of their electric bills by selling excess energy.

What is unique about Illinois’ approach is that the rebate is an upfront payment, rather than on ongoing tariff or reduced net metering compensation, for example. By allowing customers to get paid for the value solar provides to the system at the time it is installed, in the same way new wires, poles, and transformers would, this upfront payment positions DER investments as equally or more beneficial to customers and the electric grid. This is a huge step not only for regulators, but for utilities as well, as they begin to see distributed energy as an asset to the system.

This is a huge step for utilities, as they begin to see distributed energy as an asset to the system.

The rebate would also factor-in the variables of location, time, and performance of DER in the rebate formula, allowing for a more precise calculation of the value to the grid. Peak electricity demand can stress the local grid, causing wear and tear and failure of the equipment that serve our homes and businesses. Power from DER during peak times and in certain areas can alleviate those stresses, therefore providing a greater value than during times of average demand.

In addition, factoring-in the value of performance will take into account the other functions of distributed energy that help keep the lights on. For example, batteries and advanced inverters can provide support for helping avoid voltage fluctuations that can cause outages and other costs to customers.
