A series of transformer fires has caused power outages across the city the morning of February 22. Traffic lights at several intersections are also out as the GTA undergoes an intense snowfall, with reports of lightning in parts of the city.

The affected intersections include Bathurst St. and Wilson Ave., Palmerston Ave. and Queen St. W., Brookwell Drive and Streamdale Court, and Newbold Ave. and Gainsborough Rd.

At one point in the morning, there were reports of at least a dozen transformer fires. A Toronto Hydro spokesperson was unavailable for comment.

Meanwhile, the snowy conditions have created a logjam on the highways and city streets, with many collisions reported.

The heavy snow is expected to end by this afternoon, leaving up to four centimetres in its wake.

Chief Scientist: we need to transform our world into a sustainable ‘electric planet’

Hydrogen Energy Transition advances renewable energy integration via electrolysis, carbon capture and storage, and gas hybrids to decarbonize industry, steel, and transport, enable grid storage, replace ammonia feedstocks, and export clean power across continents.

 

Key Points

Scaling clean hydrogen with renewables and CCS to cut emissions in power and industry, and enable clean transport.

✅ Electrolysis and CCS provide low-emission hydrogen at scale.

✅ Balances renewables with storage and flexible gas assets.

✅ Decarbonizes steel, ammonia, heavy transport, and exports.

 

I want you to imagine a highway exclusively devoted to delivering the world’s energy. Each lane is restricted to trucks that carry one of the world’s seven large-scale sources of primary energy: coal, oil, natural gas, nuclear, hydro, solar and wind.

Our current energy security comes at a price, as Europe's power crisis shows, the carbon dioxide emissions from the trucks in the three busiest lanes: the ones for coal, oil and natural gas.

We can’t just put up roadblocks overnight to stop these trucks; they are carrying the overwhelming majority of the world’s energy supply.

But what if we expand clean electricity production carried by the trucks in the solar and wind lanes — three or four times over — into an economically efficient clean energy future?

Think electric cars instead of petrol cars. Think electric factories instead of oil-burning factories. Cleaner and cheaper to run. A technology-driven orderly transition. Problems wrought by technology, solved by technology.

Make no mistake, this will be the biggest engineering challenge ever undertaken. The energy system is huge, and even with an internationally committed and focused effort the transition will take many decades.

It will also require respectful planning and retraining to ensure affected individuals and communities, who have fuelled our energy progress for generations, are supported throughout the transition.

As Tony, a worker from a Gippsland coal-fired power station, noted from the audience on this week’s Q+A program:

The workforce is highly innovative, we are up for the challenge, we will adapt to whatever is put in front of us and we have proven that in the past.

This is a reminder that if governments, industry, communities and individuals share a vision, a positive transition can be achieved.

The stunning technology advances I have witnessed in the past ten years, such as the UK's green industrial revolution shaping the next waves of reactors, make me optimistic.

Renewable energy is booming worldwide, and is now being delivered at a markedly lower cost than ever before.

In Australia, the cost of producing electricity from wind and solar is now around A$50 per megawatt-hour.

Even when the variability is firmed with grid-scale storage solutions, the price of solar and wind electricity is lower than existing gas-fired electricity generation and similar to new-build coal-fired electricity generation.

This has resulted in substantial solar and wind electricity uptake in Australia and, most importantly, projections of a 33% cut in emissions in the electricity sector by 2030, when compared to 2005 levels.

And this pricing trend will only continue, with a recent United Nations report noting that, in the last decade alone, the cost of solar electricity fell by 80%, and is set to drop even further.

So we’re on our way. We can do this. Time and again we have demonstrated that no challenge to humanity is beyond humanity.

Ultimately, we will need to complement solar and wind with a range of technologies such as high levels of storage, including gravity energy storage approaches, long-distance transmission, and much better efficiency in the way we use energy.

But while these technologies are being scaled up, we need an energy companion today that can react rapidly to changes in solar and wind output. An energy companion that is itself relatively low in emissions, and that only operates when needed.

In the short term, as Prime Minister Scott Morrison and energy minister Angus Taylor have previously stated, natural gas will play that critical role.

In fact, natural gas is already making it possible for nations to transition to a reliable, and relatively low-emissions, electricity supply.

Look at Britain, where coal-fired electricity generation has plummeted from 75% in 1990 to just 2% in 2019.

Driving this has been an increase in solar, wind, and hydro electricity, up from 2% to 27%. At the same time, and this is key to the delivery of a reliable electricity supply, electricity from natural gas increased from virtually zero in 1990 to more than 38% in 2019.

I am aware that building new natural gas generators may be seen as problematic, but for now let’s assume that with solar, wind and natural gas, we will achieve a reliable, low-emissions electricity supply.

Is this enough? Not really.

We still need a high-density source of transportable fuel for long-distance, heavy-duty trucks.

We still need an alternative chemical feedstock to make the ammonia used to produce fertilisers.

We still need a means to carry clean energy from one continent to another.

Enter the hero: hydrogen.


Hydrogen could fill the gaps in our energy needs. Julian Smith/AAP Image
Hydrogen is abundant. In fact, it’s the most abundant element in the Universe. The only problem is that there is nowhere on Earth that you can drill a well and find hydrogen gas.

Don’t panic. Fortunately, hydrogen is bound up in other substances. One we all know: water, the H in H₂O.

We have two viable ways to extract hydrogen, with near-zero emissions.

First, we can split water in a process called electrolysis, using renewable electricity or heat and power from nuclear beyond electricity options.

Second, we can use coal and natural gas to split the water, and capture and permanently bury the carbon dioxide emitted along the way.

I know some may be sceptical, because carbon capture and permanent storage has not been commercially viable in the electricity generation industry.

But the process for hydrogen production is significantly more cost-effective, for two crucial reasons.

First, since carbon dioxide is left behind as a residual part of the hydrogen production process, there is no additional step, and little added cost, for its extraction.

And second, because the process operates at much higher pressure, the extraction of the carbon dioxide is more energy-efficient and it is easier to store.

Returning to the electrolysis production route, we must also recognise that if hydrogen is produced exclusively from solar and wind electricity, we will exacerbate the load on the renewable lanes of our energy highway.

Think for a moment of the vast amounts of steel, aluminium and concrete needed to support, build and service solar and wind structures. And the copper and rare earth metals needed for the wires and motors. And the lithium, nickel, cobalt, manganese and other battery materials needed to stabilise the system.

It would be prudent, therefore, to safeguard against any potential resource limitations with another energy source.

Well, by producing hydrogen from natural gas or coal, using carbon capture and permanent storage, we can add back two more lanes to our energy highway, ensuring we have four primary energy sources to meet the needs of the future: solar, wind, hydrogen from natural gas, and hydrogen from coal.

Furthermore, once extracted, hydrogen provides unique solutions to the remaining challenges we face in our future electric planet.

First, in the transport sector, Australia’s largest end-user of energy.

Because hydrogen fuel carries much more energy than the equivalent weight of batteries, it provides a viable, longer-range alternative for powering long-haul buses, B-double trucks, trains that travel from mines in central Australia to coastal ports, and ships that carry passengers and goods around the world.

Second, in industry, where hydrogen can help solve some of the largest emissions challenges.

Take steel manufacturing. In today’s world, the use of coal in steel manufacturing is responsible for a staggering 7% of carbon dioxide emissions.

Persisting with this form of steel production will result in this percentage growing frustratingly higher as we make progress decarbonising other sectors of the economy.

Fortunately, clean hydrogen can not only provide the energy that is needed to heat the blast furnaces, it can also replace the carbon in coal used to reduce iron oxide to the pure iron from which steel is made. And with hydrogen as the reducing agent the only byproduct is water vapour.

This would have a revolutionary impact on cutting global emissions.

Third, hydrogen can store energy, as with power-to-gas in pipelines solutions not only for a rainy day, but also to ship sunshine from our shores, where it is abundant, to countries where it is needed.

Let me illustrate this point. In December last year, I was privileged to witness the launch of the world’s first liquefied hydrogen carrier ship in Japan.

As the vessel slipped into the water I saw it not only as the launch of the first ship of its type to ever be built, but as the launch of a new era in which clean energy will be routinely transported between the continents. Shipping sunshine.

And, finally, because hydrogen operates in a similar way to natural gas, our natural gas generators can be reconfigured in the future as hydrogen-ready power plants that run on hydrogen — neatly turning a potential legacy into an added bonus.

Hydrogen-powered economy
We truly are at the dawn of a new, thriving industry.

There’s a nearly A$2 trillion global market for hydrogen come 2050, assuming that we can drive the price of producing hydrogen to substantially lower than A$2 per kilogram.

In Australia, we’ve got the available land, the natural resources, the technology smarts, the global networks, and the industry expertise.

And we now have the commitment, with the National Hydrogen Strategy unanimously adopted at a meeting by the Commonwealth, state and territory governments late last year.

Indeed, as I reflect upon my term as Chief Scientist, in this my last year, chairing the development of this strategy has been one of my proudest achievements.

The full results will not be seen overnight, but it has sown the seeds, and if we continue to tend to them, they will grow into a whole new realm of practical applications and unimagined possibilities.

Feds "changing goalposts" with 2035 net-zero electricity grid target: Sask. premier

Canada Clean Electricity Regulations outline a 2035 net-zero grid target, driving decarbonization via wind, solar, hydro, SMRs, carbon capture, and efficiency, balancing reliability, affordability, and federal-provincial collaboration while phasing out coal and limiting fossil-fuel generation.

 

Key Points

Federal rules to cap CO2 from power plants and deliver a reliable, affordable net-zero grid by 2035.

✅ Applies to fossil-fired units; standards effective by Jan 1, 2035.

✅ Promotes wind, solar, hydro, SMRs, carbon capture, and efficiency.

✅ Balances reliability, affordability, and emissions cuts; ongoing consultation.

 

Saskatchewan’s premier said the federal government is “changing goalposts” with its proposed target for a net-zero electricity grid.

“We were looking at a net-zero plan in Saskatchewan and across Canada by the year 2050. That’s now been bumped to 2035. Well there are provinces that quite frankly aren’t going to achieve those types of targets by 2035,” Premier Scott Moe said Wednesday.

Ottawa proposed the Clean Electricity Regulations – formerly the Clean Electricity Standard – as part of its target for Canada to transition to net-zero emissions by 2050.

The regulations would help the country progress towards an updated proposed goal of a net-zero electricity grid by 2035.

“They’re un-consulted, notional targets that are put forward by the federal government without working with industries, provinces or anyone that’s generating electricity,” Moe said.

The Government of Canada was seeking feedback from stakeholders on the plan’s regulatory framework document earlier this year, up until August 2022.

“The clean electricity standard is something that’s still being consulted on and we certainly heard the views of Saskatchewan – not just Saskatchewan, many other provinces – and I think that’s something that’s being reflected on,” Jonathan Wilkinson, Canada’s minister of natural resources, said during an event near Regina Wednesday.

“We also recognize that the federal government has a role to play in helping provinces to make the kinds of changes that would need to be made in order to actually achieve a clean grid,” Wilkinson added.

The information received during the consultation will help inform the development of the proposed regulations, which are expected to be released before the end of the year, according to the federal government.


NET-ZERO ELECTRICITY GRID
The federal government said its Clean Electricity Regulations (CER) is part of a suite of measures, as the country moves towards a broad “decarbonization” of the economy, with Alberta's clean electricity path illustrating provincial approaches as well.

Net-zero emissions would mean Canada’s economy would either emit no greenhouse gas emissions or offset its emissions.

The plan encourages energy efficiency, abatement and non-emitting generation technologies such as carbon capture and storage and electricity generation options such as solar, wind, geothermal, small modular nuclear reactors (SMRs) and hydro, among others.

The government suggests consumer costs could be lowered by using some of these energy efficiency techniques, alongside demand management and a shift to lower-cost wind and solar power, echoing initiatives like the SaskPower 10% rebate aimed at affordability.

The CER focuses on three principles, each tied to affordability debates like the SaskPower rate hike in Saskatchewan:

 Maximize greenhouse gas reductions to achieve the 2035 target
 Ensure a reliable electrical grid to support Canadians and the economy
 Maintain electrical affordability

“Achieving a net-zero electricity supply is key to reaching Canada’s climate targets in two ways,” the government said in its proposed regulations.

“First, it will reduce [greenhouse gas] emissions from the production of electricity. Second, using clean electricity instead of fossil fuels in vehicles, heating and industry will reduce emissions from those sectors too.

The regulations would regulate carbon dioxide emissions from electricity generating units that combust any amount of fossil fuel, have a capacity above a small megawatt threshold and sell electricity onto a regulated electricity system.

New rules would also be implemented for the development of new electricity generation units firing fossil fuels in or after 2025 and existing units. All units would be subject to emission standards by Jan. 1, 2035, at the latest.

The federal government launched consultations on the proposed regulations in March 2022.

Canada also has a 2030 emissions reduction plan that works towards meeting its Paris Agreement target to reduce emissions by 40-45 per cent from 2005 levels by 2030. This plan includes regulations to phase out coal-fired electricity by 2030.


COLLABORATION
The province recently introduced the Saskatchewan First Act, in an attempt to confirm its own jurisdiction and sovereignty when it comes to natural resources.

The act would amend Saskatchewan’s constitution to exert exclusive legislative jurisdiction under the Constitution of Canada.

The province is seeking jurisdiction over the exploration of non-renewable resources, the development, conservation and management of non-renewable natural and forestry resources, and the operation of sites and facilities for the generation and production of electrical energy.

While the federal government and Saskatchewan have come head-to-head publicly over several policy concerns in the past year, both sides remain open to collaborating on issues surrounding natural resources.

“We do have provincial jurisdiction in the development of these natural resources. We’d like to work collaboratively with the federal government on developing some of the most sustainable potash, uranium, agri-food products in the world,” Moe said.

Minister Wilkinson noted that while both the federal and provincial governments aim to respect each other’s jurisdiction, there is often some overlap, particularly in the case of environmental and economic policies, with Alberta's electricity sector changes underscoring those tensions as well.

“My view is we should endeavour to try to figure out ways that we can work together, and to ensure that we’re actually making progress for Saskatchewanians and for Canadians,” Wilkinson said.

“I think that Canadians expect us to try to figure out ways to work together, and where there are some disputes that can’t get resolved, ultimately the Supreme Court will decide on the issue of jurisdiction as they did in the case on the price on pollution.”

Moe said Saskatchewan is always open to working with the federal government, but not at the expense of its “provincial, constitutional autonomy.”

Smaller, cheaper, safer: Next-gen nuclear power, explained

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.

BC Hydro says province sleeping in, showering less in pandemic

BC Hydro pandemic electricity trends reveal weekend-like energy consumption patterns: later morning demand, earlier evenings, more cooking, streaming on smart TVs, and work-from-home routines, with tips to conserve using laptops and small appliances.

 

Key Points

Weekend-like shifts in power demand from work-from-home routines: later mornings, earlier evenings, and more streaming.

✅ Later morning electricity demand; earlier evening peaks

✅ More cooking and baking; increased streaming after dinner

✅ Conservation tips: laptops, small appliances, smart TVs

 

The latest report on electricity usage in British Columbia reveals the COVID-19 pandemic has created an atmosphere where every day feels like a Saturday, a pattern also reflected in BC electricity demand during peak seasons.

BC Hydro says overall power usage hasn't changed much, but similar Ontario electricity demand shifts suggest regional differences, while Manitoba demand fell more noticeably, and a survey of 500 people shows daily routines have shifted dramatically since mid-March when pandemic-related closures began.

The hydro report says, with nearly 40 per cent of B.C. residents working from home, trends in residential electricity use confirm almost half are sleeping in and eating breakfast later, while about a quarter say they are showering less.

Those patterns more closely resemble what hydro says is typical weekend power consumption, and could influence time-of-use rates as electricity demand occurs later in the morning and earlier in the evening.

The report also finds many people are cooking and baking more than before the pandemic, preparing the evening meal earlier, streaming or viewing more television after dinner even as Ottawa's electricity consumption dipped earlier in the pandemic, and 80 per cent are going to bed later.

Although electricity use is normal for this time of year, hydro says homebound residents can conserve by using laptops instead of desktops, small appliances such as Instant Pots instead of ovens, and streaming movies or TV shows on a smart televisions instead of game consoles, even as Hydro One peak rates continue to shape consumption patterns elsewhere.

Power bill cut for 22m Thailand houses

Thailand Covid-19 Electricity Bill Relief offers energy subsidies, tariff cuts, and free power for small meters, helping work-from-home users as authorities waive charges and discount kWh rates via EGAT, MEA, PEA for three months.

 

Key Points

Program waiving or cutting household electricity bills for 22 million homes in March-May, easing work-from-home costs.

? Free power for meters <= 5 amps; up to 10M homes

? Up to 800 kWh: pay February rate; above, 50% discount

? >3,000 kWh: 30% discount; program valid March-May

 

The Thailand cabinet has formally approved energy authorities' decision to either waive or cut electricity charges, similar to B.C. electricity relief measures, for 22 million households where people are working at home because of the coronavirus disease.

Energy Minister Sontirat Sontijirawong said after the cabinet meeting on Tuesday that the ministers acknowledged the step taken by from the Energy Regulatory Commission, the Electricity Generating Authority of Thailand, the Metropolitan Electricity Authority and the Provincial Electricity Authority and noted parallels with Ontario's COVID-19 hydro plan rolled out to support ratepayers.

The measure would be valid for three months, from March to May, and cover 22 million households. It would cost the state 23.68 billion baht in lost revenue, he said, a pattern also seen with Ontario rate reductions affecting provincial revenues.


"The measure reduces the electricity charges burden on households. It is the cost of living of the people who are working from home to support the government's control of Covid-19," Mr Sontirat said.

The business sector also wants similar assistance, echoing sentiments from Ontario manufacturers during recent price reduction efforts. He said their requests were being considered.

Free electricity is extended to households with a power meter of no more than 5 amps. Up to 10 million households are expected to benefit, although issues like electricity payment challenges in India highlight different market contexts.

For households with a power meter over 5 amps, if their consumption does not exceed 800 units (kilowat hours), they will pay as much as they did in their February bill. The amount over 800 units will be subject to a 50 per cent discount, while elsewhere B.C. commercial consumption has fallen sharply.

Large houses that consume more than 3,000 units will get a 30 per cent discount, at a time when BC Hydro demand is down 10%.

Rising Solar and Wind Curtailments in California

California Renewable Energy Curtailment highlights grid congestion, midday solar peaks, limited battery storage, and market constraints, with WEIM participation and demand response programs proposed to balance supply-demand and reduce wasted solar and wind generation.

 

Key Points

It is the deliberate reduction of solar and wind output when grid limits or low demand prevent full integration.

✅ Grid congestion restricts transmission capacity

✅ Midday solar peaks exceed demand, causing surplus

✅ Storage, WEIM, and demand response mitigate curtailment

 

California has long been a leader in renewable energy adoption, achieving a near-100% renewable milestone in recent years, particularly in solar and wind power. However, as the state continues to expand its renewable energy capacity, it faces a growing challenge: the curtailment of excess solar and wind energy. Curtailment refers to the deliberate reduction of power output from renewable sources when the supply exceeds demand or when the grid cannot accommodate the additional electricity.

Increasing Curtailment Trends

Recent data from the U.S. Energy Information Administration (EIA) highlights a concerning upward trend in curtailments in California. In 2024, the state curtailed a total of 3,102 gigawatt-hours (GWh) of electricity generated from solar and wind sources, surpassing the 2023 total of 2,660 GWh. This represents a 32.4% increase from the previous year. Specifically, 2,892 GWh were from solar, and 210 GWh were from wind, marking increases of 31.2% and 51.1%, respectively, compared to the first nine months of 2023.

Causes of Increased Curtailment

Several factors contribute to the rising levels of curtailment:

  1. Grid Congestion: California's transmission infrastructure has struggled to keep pace with the rapid growth of renewable energy sources. This congestion limits the ability to transport electricity from generation sites to demand centers, leading to curtailment.

  2. Midday Solar Peaks: Amid California's solar boom, solar energy production typically peaks during the midday when electricity demand is lower. This mismatch between supply and demand results in excess energy that cannot be utilized, necessitating curtailment.

  3. Limited Energy Storage: While battery storage technologies are advancing, California's current storage capacity is insufficient to absorb and store excess renewable energy for later use. This limitation exacerbates curtailment issues.

  4. Regulatory and Market Constraints: Existing market structures and regulatory frameworks may not fully accommodate the rapid influx of renewable energy, leading to inefficiencies and increased curtailment.

Economic and Environmental Implications

Curtailment has significant economic and environmental consequences. For renewable energy producers, curtailed energy represents lost revenue and undermines the economic viability of new projects. Environmentally, curtailment means that clean, renewable energy is wasted, and the grid may rely more heavily on fossil fuels to meet demand, counteracting the benefits of renewable energy adoption.

Mitigation Strategies

To address the rising curtailment levels, California is exploring several strategies aligned with broader decarbonization goals across the U.S.:

  • Grid Modernization: Investing in and upgrading transmission infrastructure to alleviate congestion and improve the integration of renewable energy sources.

  • Energy Storage Expansion: Increasing the deployment of battery storage systems to store excess energy during peak production times and release it during periods of high demand.

  • Market Reforms: Participating in the Western Energy Imbalance Market (WEIM), a real-time energy market that allows for the balancing of supply and demand across a broader region, helping to reduce curtailment.

  • Demand Response Programs: Implementing programs that encourage consumers to adjust their energy usage patterns, such as shifting electricity use to times when renewable energy is abundant.

Looking Ahead

As California continues to expand its renewable energy capacity, addressing curtailment will be crucial to ensuring the effectiveness and sustainability of its energy transition. By investing in grid infrastructure, energy storage, and market reforms, the state can reduce curtailment levels and make better use of its renewable energy resources, while managing challenges like wildfire smoke impacts on solar output. These efforts will not only enhance the economic viability of renewable energy projects but also contribute to California's 100% clean energy targets by maximizing the use of clean energy and reducing reliance on fossil fuels.

While California's renewable energy sector faces challenges related to curtailment, proactive measures and strategic investments can mitigate these issues, as scientists continue to improve solar and wind power through innovation, paving the way for a more sustainable and efficient energy future.
