California Rolling Blackouts expose grid reliability risks amid a heatwave, as CAISO curtails power while solar output fades at sunset, wind stalls, and scarce natural gas and nuclear capacity plus PG&E issues strain imports.

Key Points

Grid outages during heatwaves from low reserves, fading solar, weak wind, and limited firm capacity.

✅ Heatwave demand rose as solar output dropped at sunset

✅ Limited imports and gas, nuclear shortfalls cut reserves

✅ Policy, pricing, and maintenance gaps increased outage risk

Millions of Californians were denied electrical power and thus air conditioning during a heatwave, raising the risk of heatstroke and death, particularly among the elderly and sick. 

The blackouts come at a time when people, particularly the elderly, are forced to remain indoors due to Covid-19, and as later heat waves would test the grid again statewide.

At first, the state’s electrical grid operator last night asked customers to voluntarily reduce electricity use. But after lapses in power supply pushed reserves to dangerous levels it declared a “Stage 3 emergency” cutting off power to people across the state at 6:30 pm.

The immediate reason for the black-outs was the failure of a 500-megawatt power plant and an out-of-service 750-megawatt unit not being available. “There is nothing nefarious going on here,” said a spokeswoman for California Independent System Operator (CAISO). “We are just trying to run the grid.”

But the underlying reasons that California is experiencing rolling black-outs for the second time in less than a year stem from the state’s climate policies, which California policymakers have justified as necessary to prevent deaths from heatwaves, and which it is increasingly exporting to Western states as a model.

In October, Pacific Gas and Electric cut off power to homes across California to avoid starting forest fires after reports that its power lines may have started fires in recent seasons. The utility and California’s leaders had over the previous decade diverted billions meant for grid maintenance to renewables. 

And yesterday, California had to impose rolling blackouts because it had failed to maintain sufficient reliable power from natural gas and nuclear plants, or pay in advance for enough guaranteed electricity imports from other states.

It may be that California’s utilities and their regulator, the California Public Utilities Commission, which is also controlled by Gov. Newsom, didn’t want to spend the extra money to guarantee the additional electricity out of fears of raising California’s electricity prices even more than they had already raised them.

California saw its electricity prices rise six times more than the rest of the United States from 2011 to 2019, helping explain why electricity prices are soaring across the state, due to its huge expansion of renewables. Republicans in the U.S. Congress point to that massive increase to challenge justifications by Democrats to spend $2 trillion on renewables in the name of climate change.

Even though the cost of solar panels declined dramatically between 2011 and 2019, their unreliable and weather-dependent nature meant that they imposed large new costs in the form of storage and transmission to keep electricity as reliable. California’s solar panels and farms were all turning off as the blackouts began, with no help available from the states to the East already in nightfall.

Electricity from solar goes away at the very moment when the demand for electricity rises. “The peak demand was steady in late hours,” said the spokesperson for CAISO, which is controlled by Gov. Gavin Newsom, “and we had thousands of megawatts of solar reducing their output as the sunset.”

The two blackouts in less than a year are strong evidence that the tens of billions that Californians have spent on renewables come with high human, economic, and environmental costs.

Last December, a report by done for PG&E concluded that the utility’s customers could see blackouts double over the next 15 years and quadruple over the next 30.

California’s anti-nuclear policies also contributed to the blackouts. In 2013, Gov. Jerry Brown forced a nuclear power plant, San Onofre, in southern California to close.

Had San Onofre still been operating, there almost certainly would not have been blackouts on Friday as the reserve margin would have been significantly larger. The capacity of San Onofre was double that of the lost generation capacity that triggered the blackout.

California's current and former large nuclear plants are located on the coast, which allows for their electricity to travel shorter distances, and through less-constrained transmission lines than the state’s industrial solar farms, to get to the coastal cities where electricity is in highest demand.

There has been very little electricity from wind during the summer heatwave in California and the broader western U.S., further driving up demand. In fact, the same weather pattern, a stable high-pressure bubble, is the cause of heatwaves, since it brought very low wind for days on end along with very high temperatures.

Things won’t be any better, and may be worse, in the winter, with a looming shortage as it produces far less solar electricity than the summer. Solar plus storage, an expensive attempt to fix problems like what led to this blackout, cannot help through long winters of low output.

California’s electricity prices will continue to rise if it continues to add more renewables to its grid, and goes forward with plans to shut down its last nuclear plant, Diablo Canyon, in 2025.

Had California spent an estimated $100 billion on nuclear instead of on wind and solar, it would have had enough energy to replace all fossil fuels in its in-state electricity mix.

To manage the increasingly unreliable grid, California will either need to keep its nuclear plant operating, build more natural gas plants, underscoring its reliance on fossil fuels for reliability, or pay ever more money annually to reserve emergency electricity supplies from its neighbors.

After the blackouts last October, Gov. Newsom attacked PG&E Corp. for “greed and mismanagement” and named a top aide, Ana Matosantos, to be his “energy czar.” 

“This is not the new normal, and this does not take 10 years to solve,” Newsom said. “The entire system needs to be reimagined.”

Puerto Rico Tesla Solar Power enables resilient microgrids using batteries, renewable energy, and energy storage to rebuild the hurricane-damaged grid, reduce fossil fuels, cut costs, and accelerate recovery with scalable solar-plus-storage solutions.

Key Points

A solar-plus-storage plan using Tesla microgrids and batteries to restore Puerto Rico's cleaner, resilient power.

✅ Microgrids cut diesel reliance and harden critical facilities.

✅ Batteries stabilize the grid and shave peak demand costs.

✅ Scalable solar enables faster, modular disaster recovery.

Puerto Rico’s governor Ricardo Rossello has said that he will speak to Elon Musk after the Tesla inventor said his innovative solar and battery systems could be used to restore electricity on the island.

Mr Musk was mentioned in a tweet, referencing an article discussing ways to restore Puerto Rico’s power grid, which was knocked out by Hurricane Maria on September 20.

Restoring the ageing and already-weakened network has proved slow: as of Friday 90 per cent of the island remained without power. The island’s electricity company was declared bankrupt in July.

Mr Musk was asked: “Could @ElonMusk go in and rebuild #PuertoRico’s electricity system with independent solar & battery systems?”

The South African entrepreneur replied: “The Tesla team has done this for many smaller islands around the world, but there is no scalability limit, so it can be done for Puerto Rico too.

“Such a decision would be in the hands of the PR govt, PUC, any commercial stakeholders and, most importantly, the people of PR.”

His suggestion was seized upon by Mr Rossello, who then tweeted: “@ElonMusk Let's talk. Do you want to show the world the power and scalability of your #TeslaTechnologies?

“PR could be that flagship project.”

Mr Musk replied that he was happy to talk.

Restoring power to the battered island is a priority for the government, and improving grid resilience remains critical, with hospitals still running on generators and the 3.5 million people struggling with a lack of refrigeration or air conditioning.

Radios broadcast messages advising people how to keep their insulin cool, and doctors are concerned about people not being able to access dialysis.

And, with its power grid wiped out, the Caribbean island could totally rethink the way it meets its energy needs, drawing on examples like a resilient school microgrid built locally. 

“This is an opportunity to completely transform the way electricity is generated in Puerto Rico and the federal government should support this,” said Judith Enck, the former administrator for the region with the environmental protection agency.

“They need a clean energy renewables plan and not spending hurricane money propping up the old fossil fuel infrastructure.”

Forty-seven per cent of Puerto Rico’s power needs were met by burning oil last year - a very expensive and outdated method of electricity generation. For the US as a whole, petroleum accounted for just 0.3 per cent of all electricity generated in 2016 even as the grid isn’t yet running on 100% renewable energy nationwide.

The majority of the rest of Puerto Rico’s energy came courtesy of coal and natural gas, with renewables, which later faced pandemic-related setbacks, accounting for only two per cent of electricity generation.

“In that time of extreme petroleum prices, the utility was borrowing money and buying oil in order to keep those plants operating,” said Luis Martinez, a lawyer at natural resources defense council and former special aide to the president of Puerto Rico’s environmental quality board.

“That precipitated the bankruptcy that followed. It was in pretty poor shape before the storm. Once the storm got there, it finished the job.”

But Mr Martinez told the website Earther that it might be difficult to secure the financing for rebuilding Puerto Rico with renewables from FEMA (Federal Emergency Management Agency) funds.

“A lot of distribution lines were on wood poles,” he said.

“Concrete would make them more resistant to winds, but that would potentially not be authorized under the use of FEMA funds.

"We’re looking into if some of those requirements can be waived so rebuilding can be more resilient.”

PG&E dividend halt for wildfire mitigation directs cash from shareholders to tree clearing, wildfire risk reduction, and probation compliance under Judge William Alsup, amid bankruptcy, Camp Fire liabilities, and power line vegetation management mandates.

Key Points

A court-ordered dividend halt funding vegetation clearance and wildfire mitigation as PG&E meets probation terms.

✅ Judge Alsup bars dividends until mitigation targets met

✅ 375,000 trees cleared near power lines in high-risk zones

✅ Measures tied to probation amid bankruptcy and liabilities

A U.S. judge said on Tuesday that PG&E may not resume paying dividends and must use the money to fund its plan for cutting down trees to reduce the risk of wildfires in California, stopping short of more costly measures he proposed earlier this year.

The new criminal probation terms for PG&E are modest compared with ones the judge had in mind in January and that PG&E said could have cost upwards of $150 billion.

The terms will, however, keep PG&E under the supervision of Judge William Alsup of the U.S. District Court for the Northern District of California and hold the company, which also is in Chapter 11 bankruptcy and whose bankruptcy plan has drawn support from wildfire victims, to its target for clearing areas around its power lines of some 375,000 trees this year.

PG&E's probation stems from its felony conviction after a deadly 2010 natural gas pipeline blast in San Bruno, California, near San Francisco, that killed eight people and injured 58 others.

PG&E filed for bankruptcy protection on Jan. 29 in anticipation of liabilities from wildfires, including a catastrophic 2018 blaze, the Camp Fire, for which PG&E later pleaded guilty to 85 counts in state court. It killed 86 people in the deadliest and most destructive wildfire in California history.

At a January hearing, Alsup, who is overseeing PG&E's probation, said he felt compelled to propose additional probation terms in the aftermath of Camp Fire. San Francisco-based PG&E expects its equipment will be found to have caused the blaze.

The probation process is separate from San Francisco-based PG&E's bankruptcy filing and from operational measures such as its pandemic response and shutoff moratorium implemented to protect customers.

As the company faces $30 billion in wildfire liabilities and bankruptcy proceedings and has opened a wildfire assistance program for affected residents, the energy company is expected to name as its new chief executive Bill Johnson, a source said on Tuesday. Johnson has been the CEO of the Tennessee Valley Authority since 2013 and is retiring on Friday.

Additional probation terms imposed by Alsup on Tuesday will require PG&E to meet goals in a wildfire mitigation plan it unveiled in February.

The goals include removing 375,000 dead, dying or hazardous trees from areas at high risk of wildfires in 2019, compared with 160,000 last year.

The judge said PG&E will not be able to pay shareholders until it complies with his new probation terms.

Shares fell 2% on Tuesday to close at $17.66 on the New York Stock Exchange and are down 63% since November 2018 due to concerns about the company's bankruptcy and wildfire liabilities, though the utility has said rates are set to stabilize in 2025 as part of its long-term plan. The shares traded as low as $5.07 in January.

PG&E in December 2017 suspended its quarterly cash dividend, while continuing to pay significant property taxes to California counties, citing uncertainty about liabilities from wildfires in October of that year that struck Northern California.

PG&E paid $798 million in dividends in 2017 and $925 million in 2016, a period in which the company did a poor job of clearing areas around its power lines of hazardous trees, according to Alsup.

Money meant for shareholders should have been spent on efforts to reduce wildfire risks in recent years, Alsup said at Tuesday's hearing.

"PG&E has started way more than its share of these fires," Alsup said.

"I want to see the people of California safe," the judge added.

Lawyers for PG&E did not contest the new terms, which the company considers more feasible than terms Alsup proposed in January.

To comply with the terms Alsup proposed in January, PG&E said it would have to remove 100 million trees. The company added that shutting power lines during high winds as Alsup proposed would not be feasible because the lines traverse rural areas to service cities and suburbs.

Idling lines could also affect the power grid in other states, PG&E said.

Alsup on Tuesday said he was still considering his proposal to require PG&E to shut down power lines during windy weather to prevent tree branches from making contact and sparking wildfires linked to power lines in the region.

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.

Read more: How to transition from coal: 4 lessons for Australia from around the world

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.

Read more: 145 years after Jules Verne dreamed up a hydrogen future, it has arrived

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.

CAISO Clean Energy Transition outlines California's path to 100% carbon-free power by 2045, scaling renewables, battery storage, and offshore wind while safeguarding grid reliability, managing natural gas, and leveraging Western markets like EDAM.

Key Points

CAISO Clean Energy Transition is the plan to reach 100% carbon-free power by 2045 while maintaining grid reliability.

✅ Target: add 7 GW/year to reach 120 GW capacity by 2045

✅ Battery storage up 30x; smooths intermittent solar and wind

✅ EDAM and WEIM enhance imports, savings, and reliability

Mark Rothleder, Chief Operating Officer and Senior Vice President at the California Independent System Operator (CAISO), which manages roughly 80% of California’s electric grid, has expressed cautious optimism about meeting the state's ambitious clean energy targets while keeping the lights on across the grid. However, he acknowledges that this journey will not be without its challenges.

California aims to transition its power system to 100% carbon-free sources by 2045, ensuring a reliable electricity supply at reasonable costs for consumers. Rothleder, aware of the task's enormity, likens it to a complex car repair performed while the vehicle is in motion.

Recent achievements have demonstrated California's ability to temporarily sustain its grid using clean energy sources. According to Rothleder, the real challenge lies in maintaining this performance round the clock, every day of the year.

Adding thousands of megawatts of renewable energy into California’s existing 50-gigawatt system, which needs to expand to 120 gigawatts to meet the 2045 goal, poses a significant challenge, though recent grid upgrade funding offers some support for needed infrastructure. CAISO estimates that an addition of 7 gigawatts of clean power per year for the next two decades is necessary, all while ensuring uninterrupted power delivery.

While natural gas currently constitutes California's largest single source of power, Rothleder notes the need to gradually decrease reliance on it, even as it remains an operational necessity in the transition phase.

In 2023, CAISO added 5,660 megawatts of new power to the grid, with plans to integrate over 1,100 additional megawatts in the next six to eight months of 2024. Battery storage, crucial for mitigating the intermittent nature of wind and solar power, has seen substantial growth as California turns to batteries for grid support, increasing 30-fold in three years.

Rothleder emphasizes that electricity reliability is paramount, as consumers always expect power availability. He also highlights the potential of offshore wind projects to significantly contribute to California's power mix by 2045.

The offshore wind industry faces financial and supply chain challenges despite these plans. CAISO’s 20-year outlook indicates a significant increase in utility-scale solar, requiring extensive land use and wider deployment of advanced inverters for grid stability.

Addressing affordability is vital, especially as California residents face increasing utility bills. Rothleder suggests a broader energy cost perspective, encompassing utility and transportation expenses.

Despite smooth grid operations in 2023, challenges in previous years, including extreme weather-induced power outages driven by climate change, underscore the need for a robust, adaptable grid. California imports about a quarter of its power from neighbouring states and participates in the Western Energy Imbalance Market, which has yielded significant savings.

CAISO is also working on establishing an extended day-ahead electricity market (EDAM) to enhance the current energy market's success, building on insights from a Western grid integration report that supports expanded coordination.

Rothleder believes that a thoughtfully designed, diverse power system can offer greater reliability and resilience in the long run. A future grid reliant on multiple, smaller power sources such as microgrids could better absorb potential losses, ensuring a more reliable electricity supply for California.

Hybrid renewable energy projects integrate wind, solar, and battery storage to enhance grid reliability, reduce curtailment, and provide dispatchable power in markets like Alberta, leveraging photovoltaic tracking, overbuilt transformers, and improved storage economics.

Key Points

Hybrid renewable energy projects combine wind, solar, and storage to deliver reliable, dispatchable clean power.

✅ Combine wind, solar, and batteries for steady, dispatchable output

✅ Lower curtailment by using shared transformers and smart inverters

✅ Boost farm income via leases; diversify risk from oil and gas

Third-generation farmer James Praskach has been burned by the oil and gas sector and watched wicked weather pound his crops flat, but he is hoping a new kind of energy -- the renewable kind -- will pay dividends.

The 39-year-old is part of a landowner consortium that is hosting the sprawling 300-megawatt Blackspring Ridge wind power project in southeastern Alberta.

He receives regular lease payments from the $600-million project that came online in 2014, even though none of the 166 towering wind turbines that surround his land are actually on it.

His lease payments stand to rise, however, when and if the proposed 77-MW Vulcan Solar project, which won regulatory approval in 2016, is green-lighted by developer EDF Renewables Inc.

The panels would cover about 400 hectares of his family's land with nearly 300,000 photovoltaic solar panels in Alberta, installed on racks designed to follow the sun. It would stand in the way of traditional grain farming of the land, but that wouldn't have been a problem this year, Praskach says.

"This year we actually had a massive storm roll through. And we had 100 per cent hail damage on all of (the Vulcan Solar lands). We had canola, peas and barley on it this year," he said, adding the crop was covered by insurance.

Meanwhile, poor natural gas prices and a series of oilpatch financial failures mean rents aren't being paid for about half of the handful of gas wells on his land, showing how a province that is a powerhouse for both fossil and green energy can face volatility -- he's appealed to the Alberta surface Rights Board for compensation.

"(Solar power) would definitely add a level of security for our farming operations," said Praskach.

Hybrid power projects that combine energy sources are a growing trend as selling renewable energy gains traction across markets. Solar only works during the day and wind only when it is windy so combining the two -- potentially with battery storage or natural gas or biomass generation -- makes the power profile more reliable and predictable.

Globally, an oft-cited example is on El Hierro, the smallest of the Canary Islands, where wind power is used to pump water uphill to a reservoir in a volcanic crater so that it can be released to provide hydroelectric power when needed. At times, the project has provided 100 per cent of the tiny island's energy needs.

Improvements in technology such as improving solar and wind power and lower costs for storage mean it is being considered as a hybrid add-on for nearly all of its renewable power projects, said Dan Cunningham, manager of business development at Greengate Power Corp. of Calgary.

Grant Arnold, CEO of developer BluEarth Renewables, agreed.

"The barrier to date, I would say, has been cost of storage but that is changing rapidly," he said. "We feel that wind and storage or solar and storage will be a fundamental way we do business within five years. It's changing very, very rapidly and it's the product everybody wants."

Vulcan Solar was proposed after Blackspring Ridge came online, said David Warner, associate director of business development for EDF Renewables, which now co-owns the wind farm with Enbridge Inc.

"Blackspring actually had incremental capacity in the main power transformers," he said. "Essentially, it was capable of delivering more energy than Blackspring was producing. It was overbuilt."

Vulcan Solar has been sized to utilize the shortfall without producing so much energy that either will ever have to be constrained, he said. Much of the required environmental work has already been done for the wind farm.

Storage is being examined as a potential addition to the project but implementing it depends on the regulatory system. At present, Alberta's regulators are still working on how to permit and control what they call "dispatchable renewables and storage" systems.

EDF announced last spring it would proceed with the Arrow Canyon Solar Project in Nevada which is to combine 200 MW of solar with 75 MW of battery storage by 2022 -- the batteries are to soak up the sun's power in the morning and dispatch the electricity in the afternoon when Las Vegas casinos' air conditioning is most needed.

What is clear is that renewable energy will continue to grow, with Alberta renewable jobs expected to follow -- in a recent report, the International Energy Agency said global electricity capacity from renewables is set to rise by 50 per cent over the next five years, an increase equivalent to adding the current total power capacity of the United States.

The share of renewables is expected to rise from 26 per cent now to 30 per cent in 2024 but will remain well short of what is needed to meet long-term climate, air quality and energy access goals, it added.
