Ontario: First place in North America to end coal-fired power

New Zealand Energy Transition will electrify transport and industry with renewables, grid-scale solar, wind farms, geothermal, batteries, demand response, pumped hydro, and transmission upgrades to manage dry-year risk and winter peak loads.

Key Points

A shift to renewables and smart demand to decarbonise transport and industry while ensuring reliable, affordable power.

✅ Electrifies transport and industrial heat with renewables

✅ Uses demand response, batteries, and pumped hydro for resilience

✅ Targets 99%+ renewable supply, managing dry-year and peak loads

As fossil fuels are phased out over the coming decades, the Climate Change Commission (CCC) suggests electricity will take up much of the slack, aligning with the vision of a sustainable electric planet powering our vehicle fleet and replacing coal and gas in industrial processes.

But can the electricity system really provide for this increased load where and when it is needed? The answer is “yes”, with some caveats.

Our research examines climate change impacts on the New Zealand energy system. It shows we’ll need to pay close attention to demand as well as supply. And we’ll have to factor in the impacts of climate change when we plan for growth in the energy sector.

Demand for electricity to grow
While electricity use has not increased in NZ in the past decade, many agencies project steeply rising demand in coming years. This is partly due to both increasing population and gross domestic product, but mostly due to the anticipated electrification of transport and industry, which could result in a doubling of demand by mid-century.

It’s hard to get a sense of the scale of the new generation required, but if wind was the sole technology employed to meet demand by 2050, between 10 and 60 new wind farms would be needed nationwide.

Of course, we won’t only build wind farms, as renewables are coming on strong and grid-scale solar, rooftop solar, new geothermal, some new small hydro plant and possibly tidal and wave power will all have a part to play.

Managing the demand
As well as providing more electricity supply, demand management and batteries will also be important. Our modelling shows peak demand (which usually occurs when everyone turns on their heaters and ovens at 6pm in winter) could be up to 40% higher by 2050 than it is now.

But meeting this daily period of high demand could see expensive plant sitting idle for much of the time (with the last 25% of generation capacity only used about 10% of the time).

This is particularly a problem in a renewable electricity system when the hydro lakes are dry, as hydro is one of the few renewable electricity sources that can be stored during the day (as water behind the dam) and used over the evening peak (by generating with that stored water).

Demand response will therefore be needed. For example, this might involve an industrial plant turning off when there is too much load on the electricity grid.

But by 2050, a significant number of households will also need smart appliances and meters that automatically use cheaper electricity at non-peak times. For example, washing machines and electric car chargers could run automatically at 2am, rather than 6pm when demand is high.

Our modelling shows a well set up demand response system could mitigate dry-year risk (when hydro lakes are low on water) in coming decades, where currently gas and coal generation is often used.

Instead of (or as well as) having demand response and battery systems to combat dry-year risk, a pumped storage system could be built. This is where water is pumped uphill when hydro lake inflows are plentiful, and used to generate electricity during dry periods.

The NZ Battery project is currently considering the potential for this in New Zealand, and debates such as whether we would use Site C's electricity offer relevant lessons.

Almost (but not quite) 100% renewable
Dry-year risk would be greatly reduced and there would be “greater greenhouse gas emissions savings” if the Interim Climate Change Committee’s (ICCC) 2019 recommendation to aim for 99% renewable electricity was adopted, rather than aiming for 100%.

A small amount of gas-peaking plant would therefore be retained. The ICCC said going from 99% to 100% renewable electricity by overbuilding would only avoid a very small amount of carbon emissions, at a very high cost.

Our modelling supports this view. The CCC’s draft advice on the issue also makes the point that, although 100% renewable electricity is the “desired end point”, timing is important to enable a smooth transition.

Despite these views, Energy Minister Megan Woods has said the government will be keeping the target of a 100% renewable electricity sector by 2030.

Impacts of climate change
In future, the electricity system will have to respond to changing climate patterns as well, becoming resilient to climate risks over time.

The National Institute of Water and Atmospheric Research predicts winds will increase in the South Island and decrease in the far north in coming decades.

Inflows to the biggest hydro lakes will get wetter (more rain in their headwaters), and their seasonality will change due to changes in the amount of snow in these catchments.

Our modelling shows the electricity system can adapt to those changing conditions. One good news story (unless you’re a skier) is that warmer temperatures will mean less snow storage at lower elevations, and therefore higher lake inflows in the big hydro catchments in winter, leading to a better match between times of high electricity demand and higher inflows.

The price is right
The modelling also shows the cost of generating electricity is not likely to increase, because the price of building new sources of renewable energy continues to fall globally.

Because the cost of building new renewables is now cheaper than non-renewables (such as coal-fired plants), investing in carbon-free electricity is increasingly compelling, and renewables are more likely to be built to meet new demand in the near term.

While New Zealand’s electricity system can enable the rapid decarbonisation of (at least) our transport and industrial heat sectors, international efforts like cleaning up Canada's electricity underline the need for certainty so the electricity industry can start building to meet demand everywhere.

Bipartisan cooperation at government level will be important to encourage significant investment in generation and transmission projects with long lead times and life expectancies, as analyses of climate policy and grid implications underscore in comparable markets.

Infrastructure and markets are needed to support demand response uptake, as well as certainty around the Tiwai exit in 2024 and whether pumped storage is likely to be built.

Our electricity system can support the rapid decarbonisation needed if New Zealand is to do its fair share globally to tackle climate change.

But sound planning, firm decisions and a supportive and relatively stable regulatory framework are all required before shovels can hit the ground.

Alberta Capacity Market Overhaul faces scrutiny over electricity costs, reliability targets, investor certainty, and AESO design, as UCP reviews NDP reforms, renewables integration, and deregulated energy-only alternatives impacting generators, ratepayers, and future power price volatility.

Key Points

A shift paying generators for capacity and energy to improve reliability; critics warn of higher electricity costs.

✅ UCP reviewing NDP plan and subsidies amid market uncertainty

✅ AESO cites reliability needs as coal retires, renewables grow

✅ Critics predict overprocurement and premature launch cost spikes

Jason Kenney's government is facing renewed pressure to cancel a massive overhaul of Alberta's power market that one player says will needlessly spike costs by hundreds of millions of dollars, amid an electricity sector in profound change today.

Nick Clark, who owns the Calgary-based electricity retailer Spot Power, has sent the Alberta government an open letter urging it to walk away from the electricity market changes proposed by the former NDP government.

"How can you encourage new industry to open up when one of their raw material costs will increase so dramatically?" Clark said. "The capacity market will add more costs to the consumer and it will be a spiral downwards."

But NDP Leader Rachel Notley, whose government ushered in the changes, said fears over dramatic cost increases are unfounded.

"There are some players within the current electricity regime who have a vested interest in maintaining the current situation," Notley said

Kenney's UCP vowed during the recent election to review the current and proposed electricity market options, as the electricity market heads for a reshuffle, with plans to report on its findings within 90 days.

The party also promised to scrap subsidies for renewable power, while ensuring "a market-based electricity system" that emphasizes competition in Alberta's electricity market for consumers.

The New Democrats had opted to scrap the current deregulated power market — in place since the Klein era — after phasing out coal-fired generation and ushering in new renewable power as part of changes in how Alberta produces and pays for electricity under their climate change strategy.

The Alberta Electric System Operator, which oversees the grid, says the province will need new sources of electricity to replace shuttered coal plants and backstop wind and solar generators, while meeting new consumer demand.

After consulting with power companies and investors, the AESO concluded in late 2016 the electricity market couldn't attract enough investment to build the needed power generation under the current model.

The AESO said at the time investors were concerned their revenues would be uncertain once new plants are running. It recommended what's known as a capacity market, which compensates power generators for having the ability to produce electricity, even when they're not producing it.

In other words, producers would collect revenue for selling electricity into the grid and, separately, for having the capacity to produce power as a backstop, ensuring the lights stay on. Power generators would use this second source of income to help cover plant construction costs.

Clark said the complex system introduces unnecessary costs, which he believes would hurt consumers in the end. He said what's preventing investment in the power market is uncertainty over how the market will be structured in the future.

"What investors need to see in this market is price certainty, regulatory ease, and where the money they're putting into the marketplace is not at risk," he said.

"They can risk their own money, but if in fact the government comes in and changes the policy as it was doing, then money stayed away from the province."

Notley said a capacity market would not increase power bills but would avoid big price swings, with protections like a consumer price cap on power bills also debated, while bringing greener sources of energy into Alberta's grid.

"Moving back to the [deregulated] energy-only market would make a lot of money for a few people, and put consumers, both industrial and residential, at great risk."

Clark disagrees, citing Enmax's recent submissions to the Alberta Utilities Commission, in which the utility argues the proposed design of the capacity market is flawed.

In its submissions to the commission, which is considering the future of Alberta's power market, Enmax says the proposed system would overestimate the amount of generation capacity the province will need in the future. It says the calculation could result in Alberta procuring too much capacity.

The City of Calgary-owned utility says this could drive up costs by anywhere from $147 million to $849 million a year. It says a more conservative calculation of future electricity demand could avoid the extra expense.

An analysis by a Calgary energy consulting firm suggests a different feature of the proposed power market overhaul could also lead to a massive spike in costs.

EDC Associates, hired by the Consumers' Coalition of Alberta, argues the proposal to launch the new system in November 2021 may be premature, because it could bring in additional supplies of electricity before they're needed.

The consultant's report, also filed with the Alberta Utilities Commission, estimates the early launch date could require customers to pay 40 per cent more for electricity amid rising electricity prices in the province — potentially an extra $1.4 billion — in 2021/22.

"The target implementation date is politically driven by the previous government," said Duane Reid-Carlson, president of EDC Associates.

Reid-Carlson recommends delaying the launch date by several years and making another tweak: reducing the proposed target for system reliability, which would scale back the amount of power generation needed to backstop renewable sources.

"You could get a result in the capacity market that would give a similar cost to consumers that the [deregulated] energy-only market design would have done otherwise," he said.

"You could have a better risk profile associated with the capacity market that would serve consumers better through lower cost, lower price volatility, and it would serve generators better by giving them better access to capital at lower costs."

The UCP government did not respond to a request for comment.

Canada Net-Zero Electricity Buildout will double or triple power capacity, scaling clean energy, renewables, nuclear, hydro, and grid transmission, with faster permitting, Indigenous consultation, and trillions in investment to meet 2035 non-emitting regulations.

Key Points

A national plan to rapidly expand clean, non-emitting power and grid capacity to enable a net-zero economy by 2050.

✅ Double to triple generation; all sources non-emitting by 2035

✅ Accelerate permitting, transmission, and Indigenous partnerships

✅ Trillions in investment; cross-jurisdictional coordination

Canada must build more electricity generation in the next 25 years than it has over the last century in order to support a net-zero emissions economy by 2050, says a new report from the Public Policy Forum.

Reducing our reliance on fossil fuels and shifting to emissions-free electricity, as provinces such as Ontario pursue new wind and solar to ease a supply crunch, to propel our cars, heat our homes and run our factories will require doubling — possibly tripling — the amount of power we make now, the federal government estimates.

"Imagine every dam, turbine, nuclear plant and solar panel across Canada and then picture a couple more next to them," said the report, which will be published Wednesday.

It's going to cost a lot, and in Ontario, greening the grid could cost $400 billion according to one report. Most estimates are in the trillions.

It's also going to require the kind of cross-jurisdictional co-operation, with lessons from Europe's power crisis underscoring the stakes, Indigenous consultation and swift decision-making and construction that Canada just isn't very good at, the report said.

"We have a date with destiny," said Edward Greenspon, president of the Public Policy Forum. "We need to build, build, build. We're way behind where we need to be and we don't have a lot of a lot of time remaining."

Later this summer, Environment Minister Steven Guilbeault will publish new regulations to require that all power be generated from non-emitting sources by 2035 clean electricity goals, as proposed.

Greenspon said that means there are two major challenges ahead: massively expanding how much power we make and making all of it clean, even though some natural gas generation will be permitted under federal rules.

On average, it takes more than four years just to get a new electricity generating project approved by Ottawa, and more than three years for new transmission lines.

That's before a single shovel touches any dirt.

Building these facilities is another thing, and provinces such as Ontario face looming electricity shortfalls as projects drag on. The Site C dam in British Columbia won't come on line until 2025 and has been under construction since 2015. A new transmission line from northern Manitoba to the south took more than 11 years from the first proposal to operation.

"We need to move very quickly, and probably with a different approach ... no hurdles, no timeouts," Greenspon said.

There are significant unanswered questions about the new power mix, and the pace at which Canada moves away from fossil fuel power is one of the biggest political issues facing the country, with debates over whether scrapping coal-fired electricity is cost-effective still unresolved.

MARVEL microreactor debuts at Idaho National Laboratory as a 100 kW, liquid-metal-cooled, zero-emissions generator powering a nuclear microgrid, integrating wind and solar for firm, clean energy in advanced nuclear applications research.

Key Points

A 100 kW, liquid-metal-cooled INL reactor powering a nuclear microgrid and showcasing zero-emissions clean energy.

✅ 100 kW liquid-metal-cooled microreactor at INL

✅ Powers first nuclear microgrid for applications testing

✅ Integrates with wind and solar for firm clean power

Inside the Transient Reactor Test Facility, a towering, windowless gray block surrounded by barbed wire, researchers are about to embark on a mission to solve one of humanity’s greatest problems with a tiny device.

Next year, they will begin construction on the MARVEL reactor. MARVEL stands for Microreactor Applications Research Validation and EvaLuation. It’s a first-of-a-kind nuclear power generator with a mini-reactor design that is cooled with liquid metal and produces 100 kilowatts of energy. By 2024, researchers expect MARVEL to be the zero-emissions engine of the world’s first nuclear microgrid at Idaho National Laboratory (INL).

“Micro” and “tiny,” of course, are relative. MARVEL stands 15 feet tall, weighs 2,000 pounds, and can fit in a semi-truck trailer. But it's minuscule compared to conventional nuclear power plants, which span acres, produces gigawatts of electricity to power whole states, and can take more than a decade to build.

For INL, where scientists have tested dozens of reactors over the decades across an area three-quarters the size of Rhode Island, it’s a radical reimagining of the technology. This advanced reactor design could help overcome the biggest obstacles to nuclear energy: safety, efficiency, scale, cost, and competition. MARVEL is an experiment to see how all these pieces could fit together in the real world.

“It’s an applications test reactor where we’re going to try to figure out how we extract heat and energy from a nuclear reactor and apply it — and combine it with wind, solar, and other energy sources,” said Yasir Arafat, head of the MARVEL program.

The project, however, comes at a time when nuclear power is getting pulled in wildly different directions, from phase-outs to new strategies like the UK’s green industrial revolution that shapes upcoming reactors.

Germany just shut down its last nuclear reactors. The U.S. just started up its first new reactor in 30 years, underscoring a shift. France, the country with the largest share of nuclear energy on its grid, saw its atomic power output decline to its lowest since 1988 last year. Around the world, there are currently 60 nuclear reactors under construction, with 22 in China alone.

But the world is hungrier than ever for energy. Overall electricity demand is growing: Global electricity needs will increase nearly 70 percent by 2050 compared to today’s consumption, according to the Energy Information Administration. At the same time, the constraints are getting tighter. Most countries worldwide, including the U.S., have committed to net-zero goals by the middle of the century, even as demand rises.

To meet this energy demand without worsening climate change, the U.S. Energy Department’s report on advanced nuclear energy released in March said, “the U.S. will need ~550–770 [gigawatts] of additional clean, firm capacity to reach net-zero; nuclear power is one of the few proven options that could deliver this at scale.”

The U.S. government is now renewing its bets on nuclear power to produce steady electricity without emitting greenhouse gases. The Bipartisan Infrastructure Law included $6 billion to keep existing nuclear power plants running. In addition, the Inflation Reduction Act, the U.S. government’s largest investment in countering climate change, includes several provisions to benefit atomic power, including tax credits for zero-emissions energy.

“It’s a game changer,” said John Wagner, director of INL.

The tech sector is jumping in, too, as atomic energy heats up across startups and investors. In 2021, venture capital firms poured $3.4 billion into nuclear energy startups. They’re also pouring money into even more far-out ideas, like nuclear fusion power. Public opinion has also started moving. An April Gallup poll found that 55 percent of Americans favour and 44 percent oppose using atomic energy, the highest levels of support in 10 years.

Germany Nuclear Phase-Out drives policy amid gas supply risks, Nord Stream 1 shutdown fears, Russia dependency, and energy security planning, as Robert Habeck rejects extending reactors, favoring coal backup, storage, and EU diversification strategies.

Key Points

Ending Germany's last reactors by year end despite gas risks, prioritizing storage, coal backup, and EU diversification.

✅ Reactors' legal certification expires at year end

✅ Minimal gas savings from extending nuclear capacity

✅ Nord Stream 1 cuts amplify energy security risks

Germany’s vice-chancellor has defended the government’s commitment to ending the use of nuclear power at the end of this year, amid fears that Russia may halt natural gas supplies entirely.

Vice-Chancellor Robert Habeck, who is also the economy and climate minister and is responsible for energy, argued that keeping the few remaining reactors running would do little to address the problems caused by a possible natural gas shortfall.

“Nuclear power doesn’t help us there at all,” Habeck, said at a news conference in Vienna on Tuesday. “We have a heating problem or an industry problem, but not an electricity problem – at least not generally throughout the country.”

The main gas pipeline from Russia to Germany shut down for annual maintenance on Monday, as Berlin grew concerned that Moscow may not resume the flow of gas as scheduled.

The Nord Stream 1 pipeline, Germany’s main source of Russian gas, is scheduled to be out of action until July 21 for routine work that the operator says includes “testing of mechanical elements and automation systems”.

But German officials are suspicious of Russia’s intentions, particularly after Russia’s Gazprom last month reduced the gas flow through Nord Stream 1 by 60 percent.

Gazprom cited technical problems involving a gas turbine powering a compressor station that partner Siemens Energy sent to Canada for overhaul.

Germany’s main opposition party has called repeatedly to extend nuclear power by keeping the country’s last three nuclear reactors online after the end of December. There is some sympathy for that position in the ranks of the pro-business Free Democrats, the smallest party in Chancellor Olaf Scholz’s governing coalition.

In this year’s first quarter, nuclear energy accounted for 6 percent of Germany’s electricity generation and natural gas for 13 percent, both significantly lower than a year earlier. Germany has been getting about 35 percent of its gas from Russia.

Habeck said the legal certification for the remaining reactors expires at the end of the year and they would have to be treated thereafter as effectively new nuclear plants, complete with safety considerations and the likely “very small advantage” in terms of saving gas would not outweigh the complications.

Fuel for the reactors also would have to be procured and Scholz has said that the fuel rods are generally imported from Russia.

Opposition politicians have argued that Habeck’s environmentalist Green party, which has long strongly supported the nuclear phase-out, is opposing keeping reactors online for ideological reasons, even as some float a U-turn on the nuclear phaseout in response to the energy crisis.

Reducing dependency on Russia
Germany and the rest of Europe are scrambling to fill the gas storage in time for the northern hemisphere winter, even as Europe is losing nuclear power at a critical moment and reduce their dependence on Russian energy imports.

Prior to the Russian invasion of Ukraine, Berlin had said it considered nuclear energy dangerous and in January objected to European Union proposals that would let the technology remain part of the bloc’s plans for a climate-friendly future that includes a nuclear option for climate change pathway.

“We consider nuclear technology to be dangerous,” government spokesman Steffen Hebestreit told reporters in Berlin, noting that the question of what to do with radioactive waste that will last for thousands of generations remains unresolved.

While neighbouring France aimed to modernise existing reactors, Germany stayed on course to switch off its remaining three nuclear power plants at the end of this year and phase out coal by 2030.

Last month, Germany’s economy minister said the country would limit the use of natural gas for electricity production and make a temporary recourse to coal generation to conserve gas.

“It’s bitter but indispensable for reducing gas consumption,” Robert Habeck said.

ADNOC Hydrogen Export Projects target global energy transition, courting investors and equity stakes for blue and green hydrogen, ammonia shipping, CCS at Ruwais, and long-term supply contracts across power, transport, and industrial sectors.

Key Points

ADNOC plans blue and green hydrogen exports, leveraging Ruwais, CCS, and ammonia to secure long-term supply.

✅ Blue hydrogen via gas reforming with CCS; ammonia for shipping.

✅ Green hydrogen from solar-powered electrolysis under development.

✅ Ruwais expansions and Fertiglobe ammonia tie-up target long-term supply.

Abu Dhabi is seeking investors to help build hydrogen-export facilities, as Middle Eastern oil producers plan to adopt cleaner energy solutions, sources told Bloomberg.

Abu Dhabi National Oil Company (ADNOC) is holding talks with energy companies for them to purchase equity stakes in the hydrogen projects, the sources referred, as Germany's hydrogen strategy signals rising import demand.

ADNOC, which already produces hydrogen for its refineries, also aims to enter into long-term supply contracts, as Canada-Germany clean energy cooperation illustrates growing cross-border demand, before making any progress with these investments.

Amid a global push to reduce greenhouse-gas emissions, the state-owned oil companies in the Gulf region seek to turn their expertise in exporting liquid fuel into shipping hydrogen or ammonia across the world for clean and universal electricity needs, transport, and industrial use.

Most of the ADNOC exports are expected to be blue hydrogen, created by converting natural gas and capturing the carbon dioxide by-product that can enable using CO2 to generate electricity approaches, according to Bloomberg.

The sources said that the Abu Dhabi-based company will raise its production of hydrogen by expanding an oil-processing plant and the Borouge petrochemical facility at the Ruwais industrial hub, supporting a sustainable electric planet vision, as the extra hydrogen will be used for an ammonia facility planned with Fertiglobe.

Abu Dhabi also plans to develop green hydrogen, similar to clean hydrogen in Canada initiatives, which is generated from renewable energy such as solar power.

Noteworthy to mention, in May 2021, ADNOC announced that it will construct a world-scale blue ammonia production facility in Ruwais in Abu Dhabi to contribute to the UAE's efforts to create local and international hydrogen value chains.
