Duke Energy will build between 100 and 400 electricity-generating mini solar power plants throughout North Carolina over the next two years in one of the first large-scale initiatives of its kind in the United States according to their CEO, Jim Rogers.

“Solar and wind are both going to be key parts of our strategy going forward,” Rogers told reporters following the company’s annual meeting.

The North Carolina Utilities Commission issued a decision allowing Duke Energy to proceed with its $50 million proposal to install solar panels on the roofs and grounds of homes, schools, office buildings, shopping malls, warehouses and industrial plants, starting later this year.

Collectively, the solar sites will generate enough electricity to power 1,300 homes.

The electricity will flow directly from the solar sites to the electrical grid that serves all customers.

Duke EnergyÂ’s solar initiative will be among the nationÂ’s first and largest demonstrations of distributed generation, in which electricity is produced at numerous micro generating sites rather than at a large, centralized, traditional power plant.

Duke Energy will own and maintain the solar panels during their expected 25-year lifespan. The company also will own the electricity generated.

It will pay a rental fee to property owners who host the panels for use of their roofs or land, based on the size of the installation and amount of electricity generated at any given site.

British Columbians can access more in EV charger rebates

B.C. EV Charging Rebates boost CleanBC incentives as NRCan and ZEVIP funding covers up to 75% of Level 2 and DC fast-charger purchase and installation costs for homes, workplaces, condos, apartments, and fleet operators.

 

Key Points

Incentives in B.C. cover up to 75% of Level 2 and DC fast charger costs for homes, workplaces, and fleets.

✅ Up to 75% back; Level 2 max $5,000; DC fast max $75,000 for fleets.

✅ Eligible sites: homes, workplaces, condos, apartments, fleet depots.

✅ Funded by CleanBC with NRCan ZEVIP; time-limited top-up.

 

The Province and Natural Resources Canada (NRCan) are making it more affordable for people to install electric vehicle (EV) charging stations in their homes, businesses and communities, as EV demand ramps up across the province.

B.C. residents, businesses and municipalities can receive higher rebates for EV charging stations through the CleanBC Go Electric EV Charger Rebate and Fleets programs. For a limited time, funding will cover as much as 75% of eligible purchase and installation costs for EV charging stations, which is an increase from the previous 50% coverage.

“With electric vehicles representing 13% of all new light-duty vehicles sold in B.C. last year, our province has the strongest adoption rate of electric vehicles in Canada. We’re positioning ourselves to become leaders in the EV industry,” said Bruce Ralston, B.C.’s Minister of Energy, Mines and Low Carbon Innovation. “We’re working with our federal partners to increase rebates for home, workplace and fleet charging, and making it easier and more affordable for people to make the switch to electric vehicles.”

With a $2-million investment through NRCan’s Zero-Emission Vehicle Infrastructure Program (ZEVIP) to top up the Province’s EV Charger Rebate program, workplaces, condominiums and apartments can get a rebate for a Level 2 charging station for as much as 75% of purchase and installation costs to a maximum of $5,000. As many as 360 EV chargers will be installed through the program.

“We’re making electric vehicles more affordable and charging more accessible where Canadians live, work and play,” said Jonathan Wilkinson, federal Minister of Natural Resources. “Investing in more EV chargers, like the ones announced today in British Columbia, will put more Canadians in the driver’s seat on the road to a net-zero future and help achieve our climate goals.”

Through the CleanBC Go Electric Fleets program and in support of B.C. businesses that own and operate fleet vehicles, NRCan has invested $1.54 million through ZEVIP to top up rebates. Fleet operators can get combined rebates from NRCan and the Province for a Level 2 charging station as much as 75% to a maximum of $5,000 of purchase and installation costs, and 75% to a maximum of $75,000 for a direct-current, fast-charging station. As many as 450 EV chargers will be installed through the program.

CleanBC is a pathway to a more prosperous, balanced and sustainable future. It supports government’s commitment to climate action to meet B.C.’s emission targets and build a cleaner, stronger economy.

Quick Facts:

  • A direct-current fast charger on the BC Electric Highway allows an EV to get 100-300 kilometres of range from 30 minutes of charging.
  • Faster chargers, which give more range in less time, are coming out every year.
  • A Level 2 charger allows an EV to get approximately 30 kilometres of range per hour of charging.
  • It uses approximately the same voltage as a clothes dryer and is usually installed in homes, workplaces or for fleets to get a faster charge than a regular outlet, or in public places where people might park for a longer time.
  • A key CleanBC action is to strengthen the Zero-Emission Vehicles Act to require light-duty vehicle sales to be 26% zero-emission vehicles (ZEVs) by 2026, 90% by 2030 and 100% by 2035, five years ahead of the original target.
  • At the end of 2021, B.C. had more than 3,000 public EV charging stations and almost 80,000 registered ZEVs.

A tenth of all electricity is lost in the grid - superconducting cables can help

High-Temperature Superconducting Cables enable lossless, high-voltage, underground transmission for grid modernization, linking renewable energy to cities with liquid nitrogen cooling, boosting efficiency, cutting emissions, reducing land use, and improving resilience against disasters and extreme weather.

 

Key Points

Liquid-nitrogen-cooled power cables delivering electricity with near-zero losses, lower voltage, and greater resilience.

✅ Near-lossless transmission links renewables to cities efficiently

✅ Operate at lower voltage, reducing substation size and cost

✅ Underground, compact, and resilient to extreme weather events

 

For most of us, transmitting power is an invisible part of modern life. You flick the switch and the light goes on.

But the way we transport electricity is vital. For us to quit fossil fuels, we will need a better grid, with macrogrid planning connecting renewable energy in the regions with cities.

Electricity grids are big, complex systems. Building new high-voltage transmission lines often spurs backlash from communities, as seen in Hydro-Que9bec power line opposition over aesthetics and land use, worried about the visual impact of the towers. And our 20th century grid loses around 10% of the power generated as heat.

One solution? Use superconducting cables for key sections of the grid. A single 17-centimeter cable can carry the entire output of several nuclear plants. Cities and regions around the world have done this to cut emissions, increase efficiency, protect key infrastructure against disasters and run powerlines underground. As Australia prepares to modernize its grid, it should follow suit with smarter electricity infrastructure initiatives seen elsewhere. It's a once-in-a-generation opportunity.


What's wrong with our tried-and-true technology?
Plenty.

The main advantage of high voltage transmission lines is they're relatively cheap.

But cheap to build comes with hidden costs later. A survey of 140 countries found the electricity currently wasted in transmission accounts for a staggering half-billion tons of carbon dioxide—each year.

These unnecessary emissions are higher than the exhaust from all the world's trucks, or from all the methane burned off at oil rigs.

Inefficient power transmission also means countries have to build extra power plants to compensate for losses on the grid.

Labor has pledged A$20 billion to make the grid ready for clean energy, and international moves such as US-Canada cross-border approvals show the scale of ambition needed. This includes an extra 10,000 kilometers of transmission lines. But what type of lines? At present, the plans are for the conventional high voltage overhead cables you see dotting the countryside.

System planning by Australia's energy market operator shows many grid-modernizing projects will use last century's technologies, the conventional high voltage overhead cables, even as Europe's HVDC expansion gathers pace across its network. If these plans proceed without considering superconductors, it will be a huge missed opportunity.


How could superconducting cables help?
Superconduction is where electrons can flow without resistance or loss. Built into power cables, it holds out the promise of lossless electricity transfer, over both long and short distances. That's important, given Australia's remarkable wind and solar resources are often located far from energy users in the cities.

High voltage superconducting cables would allow us to deliver power with minimal losses from heat or electrical resistance and with footprints at least 100 times smaller than a conventional copper cable for the same power output.

And they are far more resilient to disasters and extreme weather, as they are located underground.

Even more important, a typical superconducting cable can deliver the same or greater power at a much lower voltage than a conventional transmission cable. That means the space needed for transformers and grid connections falls from the size of a large gym to only a double garage.

Bringing these technologies into our power grid offers social, environmental, commercial and efficiency dividends.

Unfortunately, while superconductors are commonplace in Australia's medical community (where they are routinely used in MRI machines and diagnostic instruments) they have not yet found their home in our power sector.

One reason is that superconductors must be cooled to work. But rapid progress in cryogenics means you no longer have to lower their temperature almost to absolute zero (-273℃). Modern "high temperature" superconductors only need to be cooled to -200℃, which can be done with liquid nitrogen—a cheap, readily available substance.

Overseas, however, they are proving themselves daily. Perhaps the most well-known example to date is in Germany's city of Essen. In 2014, engineers installed a 10 kilovolt (kV) superconducting cable in the dense city center. Even though it was only one kilometer long, it avoided the higher cost of building a third substation in an area where there was very limited space for infrastructure. Essen's cable is unobtrusive in a meter-wide easement and only 70cm below ground.

Superconducting cables can be laid underground with a minimal footprint and cost-effectively. They need vastly less land.

A conventional high voltage overhead cable requires an easement of about 130 meters wide, with pylons up to 80 meters high to allow for safety. By contrast, an underground superconducting cable would take up an easement of six meters wide, and up to 2 meters deep.

This has another benefit: overcoming community skepticism. At present, many locals are concerned about the vulnerability of high voltage overhead cables in bushfire-prone and environmentally sensitive regions, as well as the visual impact of the large towers and lines. Communities and farmers in some regions are vocally against plans for new 85-meter high towers and power lines running through or near their land.

Climate extremes, unprecedented windstorms, excessive rainfall and lightning strikes can disrupt power supply networks, as the Victorian town of Moorabool discovered in 2021.

What about cost? This is hard to pin down, as it depends on the scale, nature and complexity of the task. But consider this—the Essen cable cost around $20m in 2014. Replacing the six 500kV towers destroyed by windstorms near Moorabool in January 2020 cost $26 million.

While superconducting cables will cost more up front, you save by avoiding large easements, requiring fewer substations (as the power is at a lower voltage), and streamlining approvals.


Where would superconductors have most effect?
Queensland. The sunshine state is planning four new high-voltage transmission projects, to be built by the mid-2030s. The goal is to link clean energy production in the north of the state with the population centers of the south, similar to sending Canadian hydropower to New York to meet demand.

Right now, there are major congestion issues between southern and central Queensland, and subsea links like Scotland-England renewable corridors highlight how to move power at scale. Strategically locating superconducting cables here would be the best location, serving to future-proof infrastructure, reduce emissions and avoid power loss.

Sustainable Marine now delivering electricity to Nova Scotia grid from tidal energy

Sustainable Marine tidal energy delivers in-stream power to Nova Scotia's grid from Grand Passage, proving low-impact, renewable generation and advancing a floating tidal array at FORCE and Minas Passage in the Bay of Fundy.

 

Key Points

The first in-stream tidal project supplying clean power to Nova Scotia's grid, proven at Grand Passage.

✅ First to deliver in-stream tidal power to Canada's grid

✅ Demonstration at Grand Passage informs FORCE deployments

✅ Low-impact design and environmental monitoring validated

 

Sustainable Marine has officially powered up its tidal energy operation in Canada and is delivering clean electricity to the power system in Nova Scotia, on the country’s Atlantic coast, as the province moves to increase wind and solar projects in the years ahead. The company’s system in Grand Passage is the first to deliver in-stream tidal power to the grid in Canada, following provincial approval to harness Bay of Fundy tides that is spurring further development.

The system start-up is the culmination of more than a decade of research, development and testing, including lessons from Scottish tidal projects in recent years and a powerful tidal turbine feeding onshore grids, managing the technical challenges associated with operating in highly energetic environments and proving the ultra-low environmental impact of the tidal technology.

Sustainable Marine is striving to deliver the world’s first floating tidal array at FORCE (Fundy Ocean Research Centre for Energy). This project will be delivered in phases, drawing upon the knowledge gained and lessons learned in Grand Passage, and insights from offshore wind pilots like France’s first offshore wind turbine in Europe. In the coming months the company will continue to operate the platform at its demonstration site at Grand Passage, gradually building up power production, while New York and New England clean energy demand continues to rise, to further prove the technology and environmental monitoring systems, before commencing deployments in the Minas Passage – renowned as the Everest of tidal energy.

The Bay of Fundy’s huge tidal energy resource contains more than four times the combined flow of every freshwater river in the world, with the potential to generate approximately 2,500 MW of green energy, underscoring why independent electricity planning will be important for integrating marine renewables.

Is Hydrogen The Future For Power Companies?

Hydrogen Energy Transition accelerates green hydrogen, electrolyzers, renewables, and fuel cells, as the EU and US scale decarbonization, NextEra tests hydrogen-to-power, and DOE funds pilots to replace natural gas and cut CO2.

 

Key Points

A shift to deploy green hydrogen tech to decarbonize power, industry, and transport across EU and US energy systems.

✅ EU targets 40 GW electrolyzers plus 40 GW imports by 2030

✅ DOE funds pilots; NextEra trials hydrogen-to-power at Okeechobee

✅ Aims to replace natural gas, enable fuel cells, cut CO2

 

Last month, the European Union set out a comprehensive hydrogen strategy as part of its goal to achieve carbon neutrality for all its industries by 2050. The EU has an ambitious target to build out at least 40 gigawatts of electrolyzers within its borders by 2030 and also support the development of another 40 gigawatts of green hydrogen in nearby countries that can export to the region by the same date. The announcement came as little surprise, given that Europe is regarded as being far ahead of the United States in the shift to renewable energy, even as it looks to catch up on fuel cells with Asian leaders today.

But the hydrogen bug has finally arrived stateside: The U.S. Department of Energy has unveiled the H2@Scale initiative whereby a handful of companies including Cummins Inc. (NYSE: CMI), Caterpillar Inc.(NYSE: CAT), 3M Company (NYSE: MMM), Plug Power Inc.(NASDAQ: PLUG) and EV startup Nikola Corp.(NASDAQ: NKLA), even as the industry faces threats to the EV boom that investors are watching, will receive $64 million in government funding for hydrogen research projects.

Hot on the heels of the DoE initiative: American electric utility and renewable energy giant, NextEra Energy Inc.(NYSE: NEE), has unveiled an equally ambitious plan to start replacing its natural gas-powered plants with hydrogen.

During its latest earnings call, NextEra’s CFO Rebecca Kujawa said the company is “…particularly excited about the long-term potential of hydrogen” and discussed plans to start a pilot hydrogen project at one of its generating stations at Okeechobee Clean Energy Center owned by its subsidiary, Florida Power & Light (FPL). NextEra reported Q2 revenue of $4.2B (-15.5% Y/Y), which fell short of Wall Street’s consensus by $1.12B while GAAP EPS of $2.59 (+1.1% Y/Y) beat estimates by $0.09. The company attributed the big revenue slump to the effects of Covid-19.

Renewable energy and hydrogen stocks have lately become hot property as EV adoption hits an inflection point worldwide, with NEE up 16% in the year-to-date; PLUG +144%, Bloom Energy Corp. (NYSE: BE) +62.8% while Ballard Power Systems (NASDAQ: BLDP) has gained 98.2% over the timeframe.

NextEra’s usual modus operandi involves conducting small experiments with new technologies to establish their cost-effectiveness, a pragmatic approach informed by how electricity changed in 2021 across the grid, before going big if the trials are successful.

CFO Kujawa told analysts:
“Based on our ongoing analysis of the long-term potential of low-cost renewables, we remain confident as ever that wind, solar, and battery storage will be hugely disruptive to the country’s existing generation fleet, while reducing cost for customers and helping to achieve future CO2 emissions reductions. However, to achieve an emissions-free future, we believe that other technologies will be necessary, and we are particularly excited about the long-term potential of hydrogen.”

NextEra plans to test the electricity-to-hydrogen-to-electricity model at its natural gas-powered Okeechobee Clean Energy Center that came online in 2019. Okeechobee is already regarded as one of the cleanest thermal energy facilities anywhere on the globe. However, replacing natural gas with zero emissions hydrogen would be a significant step in helping the company achieve its goal to become 100% emissions-free by 2050.

Kujawa said the company plans to continue evaluating other potential hydrogen opportunities to accelerate the decarbonization of transportation fuel, amid the debate over the future of vehicles between electricity and hydrogen, and industrial feedstock and also support future demand for low-cost renewables.

Another critical milestone: NextEra finished the quarter with a renewables backlog of approximately 14,400 megawatts, its largest in its 20-year development history. To put that backlog into context, NextEra revealed that it is larger than the operating wind and solar portfolios of all but two companies in the world.

Hydrogen Bubble?
That said, not everybody is buying the hydrogen hype.

Barron’s Bill Apton says Wall Street has discovered hydrogen this year and that hydrogen stocks are a bubble, even as hybrid vehicles gain momentum in the U.S. market according to recent reports. Apton says the huge runup by Plug Power, Ballard Energy, and Bloom Energy has left them trading at more than 50x future cash flow, making it hard for them to grow into their steep valuations. He notes that smaller hydrogen companies are up against big players and deep-pocketed manufacturers, including government-backed rivals in China and the likes of Cummins.

According to Apton, it could take a decade or more before environmentally-friendly hydrogen can become competitive with natural gas on a cost-basis, while new ideas like flow battery cars also vie for attention, making hydrogen stocks better long-term picks than the cult stocks they have become.

European gas prices fall to pre-Ukraine war level

European Gas Prices hit pre-invasion lows as LNG inflows, EU storage gains, and softer oil markets ease the energy crisis, while recession risks, windfall taxes, and ExxonMobil's challenge shape demand and policy.

 

Key Points

European gas prices reflect supply, LNG inflows, storage, and policy, shaping energy costs for households and industry.

✅ Month-ahead hit €76.78/MWh, rebounding to €85.50/MWh.

✅ EU storage 83.2% filled; autumn peak exceeded 95%.

✅ Demand tempered by recession risks; LNG inflows offset Russian cuts.

 

European gas prices have dipped to a level last seen before Russia launched its invasion of Ukraine in February, after warmer weather across the continent eased concerns over shortages and as coal demand dropped across Europe during winter.

The month-ahead European gas future contract dropped as low as €76.78 per megawatt hour on Wednesday, the lowest level in 10 months, amid EU talks on gas price cap strategies that could shape markets, before closing higher at €83.70, according to Refinitiv, a data company.

The invasion roiled global energy markets, serving as a wake-up call to ditch fossil fuels for policymakers, and forced European countries, including industrial powerhouse Germany, to look for alternative suppliers to those funding the Kremlin. Europe had continued to rely on Russian gas even after its 2014 annexation of Crimea and support for separatists in eastern Ukraine.

On Tuesday 83.2% of EU gas storage was filled, data from industry body Gas Infrastructure Europe showed. The EU in May set a target of filling 80% of its gas storage capacity by the start of November to prepare for winter, and weighed emergency electricity measures to curb prices as needed. It hit that target in August, and by mid-November it had peaked at more than 95%.

Gas prices bounced further off the 10-month low on Thursday to reach €85.50 per megawatt hour.

Europe has several months of domestic heating demand ahead, and some industry bosses believe energy shortages could also be a problem next winter, with a worst energy nightmare still possible if supplies tighten. However, traders have also had to weigh the effects of recessions expected in several big European economies, which could dent energy demand.

UK gas prices have also dropped back from their highs earlier this year, and forecasts suggest UK energy bills to drop in April. The day-ahead gas price closed at 155p per therm on Wednesday, compared with 200p/therm at the start of 2022, and more than 500p/therm in August.

Europe’s response to the prospect of gas shortages also included campaigns to reduce energy use – a strategy belatedly adopted by the UK – and windfall taxes on energy companies to help raise revenues for governments, many of which have started expensive subsidies to cushion the impact of high energy prices for households and consumers. Energy companies have enjoyed huge profits at the expense of businesses and households this year, as EU inflation accelerated, but costs remained much the same.

However, the US oil company ExxonMobil on Wednesday launched a legal challenge against EU plans for a windfall tax on oil companies, according to filings by its German and Dutch subsidiaries at the European general court in Luxembourg. ExxonMobil argued that the windfall tax would be “counter-productive” because it said it would result in lower investment in fossil fuel extraction, and that the EU did not have the legal jurisdiction to impose it.

ExxonMobil’s move has prompted anger among European politicians. A message posted on the Twitter account of Paolo Gentiloni, the EU’s commissioner for the economy, on Thursday stated: “Fairness and solidarity, even for corporate giants. #Exxon.”

Oil prices are significantly lower than they were before the start of Russia’s invasion, and only marginally above where they were at the start of 2022. Brent crude oil futures traded at $100 a barrel on 28 February, but were at $81.84 on Thursday.

Oil prices dropped by 1.7% on Thursday. Prices had risen from 12-month lows in early December as traders hoped for increased demand from China after it relaxed its coronavirus restrictions. However, Covid-19 infection numbers are thought to have surged in the country, prompting the US to require travellers from China to show a negative test for the disease and tempering expectations for a rapid increase in oil demand.

Opinion: UK Natural Gas, Rising Prices and Electricity

European Energy Market Crisis drives record natural gas and electricity prices across the EU, as LNG supply constraints, Russian pipeline dependence, marginal pricing, and renewables integration expose volatility in liberalised power markets.

 

Key Points

A 2021 surge in European gas and electricity prices from supply strains, demand rebounds, and marginal pricing exposure.

✅ Record TTF gas and day-ahead power prices across Europe

✅ LNG constraints and Russian pipeline dependence tightened supply

✅ Debate over marginal pricing vs regulated models intensifies

 

By Ronan Bolton

The year 2021 was a turbulent one for energy markets across Europe, as Europe's energy nightmare deepened across the region. Skyrocketing natural gas prices have created a sense of crisis and will lead to cost-of-living problems for many households, as wholesale costs feed through into retail prices for gas and electricity over the coming months.

This has created immediate challenges for governments, but it should also encourage us to rethink the fundamental design of our energy markets as we seek to transition to net zero, with many viewing it as a wake-up call to ditch fossil fuels across the bloc.

This energy crisis was driven by a combination of factors: the relaxation of Covid-19 lockdowns across Europe created a surge in demand, while cold weather early in the year diminished storage levels and contributed to increasing demand from Asian economies. A number of technical issues and supply-side constraints also combined to limit imports of liquefied natural gas (LNG) into the continent.

Europe’s reliance on pipeline imports from Russia has once again been called into question, as Gazprom has refused to ride to the rescue, only fulfilling its pre-existing contracts. The combination of these, and other, factors resulted in record prices – the European benchmark price (the Dutch TTF Gas Futures Contract) reached almost €180/MWh on 21 December, with average day-ahead electricity prices exceeding €300/MWh across much of the continent in the following days.

Countries which rely heavily on natural gas as a source of electricity generation have been particularly exposed, with governments quickly put under pressure to intervene in the market.

In Spain the government and large energy companies have clashed over a proposed windfall tax on power producers. In Ireland, where wind and gas meet much of the country’s surging electricity demand, the government is proposing a €100 rebate for all domestic energy consumers in early 2022; while the UK government is currently negotiating a sector-wide bailout of the energy supply sector and considering ending the gas-electricity price link to curb bills.

This follows the collapse of a number of suppliers who had based their business models on attracting customers with low prices by buying cheap on the spot market. The rising wholesale prices, combined with the retail price cap previously introduced by the Theresa May government, led to their collapse.

While individual governments have little control over prices in an increasingly globalised and interconnected natural gas market, they can exert influence over electricity prices as these markets remain largely national and strongly influenced by domestic policy and regulation. Arising from this, the intersection of gas and power markets has become a key site of contestation and comment about the role of government in mitigating the impacts on consumers of rising fuel bills, even as several EU states oppose major reforms amid the price spike.

Given that renewables are constituting an ever-greater share of production capacity, many are now questioning why gas prices play such a determining role in electricity markets.

As I outline in my forthcoming book, Making Energy Markets, a particular feature of the ‘European model’ of liberalised electricity trade since the 1990s has been a reliance on spot markets to improve the efficiency of electricity systems. The idea was that high marginal prices – often set by expensive-to-run gas peaking plants – would signal when capacity limits are reached, providing clear incentives to consumers to reduce or delay demand at these peak periods.

This, in theory, would lead to an overall more efficient system, and in the long run, if average prices exceeded the costs of entering the market, new investments would be made, thus pushing the more expensive and inefficient plants off the system.

The free-market model became established during a more stable era when domestically-sourced coal, along with gas purchased on long-term contracts from European sources (the North Sea and the Netherlands), constituted a much greater proportion of electricity generation.

While prices fluctuated, they were within a somewhat predictable range, and provided a stable benchmark for the long-term contracts underpinning investment decisions. This is no longer the case as energy markets become increasingly volatile and disrupted during the energy transition.

The idea that free price formation in a competitive market, with governments standing back, would benefit electricity consumers and lead to more efficient systems was rooted in sound economic theory, and is the basis on which other major commodity markets, such as metals and agricultural crops, have been organised for decades.

The free-market model applied to electricity had clear limitations, however, as the majority of domestic consumers have not been exposed directly to real-time price signals. While this is changing with the roll-out of smart meters in many countries, the extent to which the average consumer will be willing or able to reduce demand in a predicable way during peak periods remains uncertain.

Also, experience shows that governments often come under pressure to intervene in markets if prices rise sharply during periods of scarcity, thus undermining a basic tenet of the market model, with EU gas price cap strategies floated as one option.

Given that gas continues to play a crucial role in balancing supply and demand for electricity, the options available to governments are limited, illustrating why rolling back electricity prices is harder than it appears for policymakers. One approach would be would be to keep faith with the liberalised market model, with limited interventions to help consumers in the short term, while ultimately relying on innovations in demand side technologies and alternatives to gas as a means of balancing systems with high shares of variable renewables.

An alternative scenario may see a return to old style national pricing policies, involving a move away from marginal pricing and spot markets, even as the EU prepares to revamp its electricity market in response. In the past, in particular during the post-WWII decades, and until markets were liberalised in the 1990s, governments have taken such an approach, centrally determining prices based on the costs of delivering long term system plans. The operation of gas plants and fuel procurement would become a much more regulated activity under such a model.

Many argue that this ‘traditional model’ better suits a world in which governments have committed to long-term decarbonisation targets, and zero marginal cost sources, such as wind and solar, play a more dominant role in markets and begin to push down prices.

A crucial question for energy policy makers is how to exploit this deflationary effect of renewables and pass-on cost savings to consumers, whilst ensuring that the lights stay on.

Despite the promise of storage technologies such as grid-scale batteries and hydrogen produced from electrolysis, aside from highly polluting coal, no alternative to internationally sourced natural gas as a means of balancing electricity systems and ensuring our energy security is immediately available.

This fact, above all else, will constrain the ambitions of governments to fundamentally transform energy markets.
