About 40 Central Virginia farmers got insights into how to make their operations more energy efficient at a recent conference.

“Managing Energy on Virginia Farms” was held at the Cumberland County Community Center. Sponsors were Virginia Cooperative Extension; James Madison University; the Virginia Department of Mines, Minerals and Energy; the Virginia Foundation for Agriculture, Innovation & Rural Sustainability; and Virginia Tech.

Speakers addressed agricultural lighting and fan ventilation, wind and solar energy and U.S. Department of Agriculture energy programs and funding during the first half of the daylong conference.

Afternoon breakout sessions addressed specific electricity uses on poultry and dairy farms. Richard Hiatt, president and executive manager of the Rural Electricity Resource Council, told participants that in 2007 U.S. farmers spent an estimated $4 billion on electricity.

“If anything, (that annual cost) seems to be increasing or at least steady each year,” Hiatt said. The first step for farm operators who want to increase their energy efficiency and identify potential savings, he said, is to make a list of everything on the farm that uses electricity, from the lights in the poultry house and the pump in the well to the heating in the farm office and the air compressor in the shop. Next, group the uses into categories such as lighting, ventilation and material handling. Consider the amount of electricity each category consumes and the category’s hours of run time. Then review at least a year’s worth of utility bills to document present usage; note any seasonal or other demand changes.

“You’ve got to get into the bills,” Hiatt said. “You’ve got to get some sort of benchmark.”

Hiatt also talked about lighting options for animal buildings, which frequently have many light fixtures. “If you have a light on for a long time, you can do better than an incandescent bulb,” he said, adding that comparing options and cost is important before purchasing new fixtures. The same goes for ventilation systems, he said. He recommended getting fans’ performance ratings from suppliers.

Dick Peterson, president of Northeast Agriculture Technology Corp., agreed and emphasized the need to keep fans in good working order. Checking belt tension and alignment is critical, he said, and some work environments necessitate cleaning fans as often as four times a year. “If you don’t maintain that fan, the efficiencies go away fairly quickly.”

France Demonstrates the Role of Nuclear Power Plants

France Nuclear Power Strategy illustrates a low-carbon, reliable baseload complementing renewables in the energy transition, enhancing grid reliability, energy security, and emissions reduction, offering actionable lessons for Germany on infrastructure, policy, and public acceptance.

 

Key Points

France's nuclear strategy is a low-carbon baseload model supporting renewables, grid reliability, and energy security.

✅ Stable low-carbon baseload complements intermittent renewables

✅ Enhances grid reliability and national energy security

✅ Requires long-term investment, safety, and waste management

 

In recent months, France has showcased the critical role that nuclear power plants can play in an energy transition, offering valuable lessons for Germany and other countries grappling with their own energy challenges. As Europe continues to navigate its path towards a sustainable and reliable energy system, France's experience with nuclear energy underscores its potential benefits and the complexities involved, including outage risks in France that operators must manage effectively.

France, a long-time proponent of nuclear energy, generates about 70% of its electricity from nuclear power, making it one of the most nuclear-dependent countries in the world. This high reliance on nuclear energy has allowed France to maintain a stable and low-carbon electricity supply, which is increasingly significant as nations aim to reduce greenhouse gas emissions, even as Europe's nuclear capacity declines in several markets, and combat climate change.

Recent events in France have highlighted several key aspects of nuclear power's role in energy transition:

  1. Reliability and Stability: During periods of high renewable energy generation or extreme weather events, nuclear power plants have proven to be a stable and reliable source of electricity. Unlike solar and wind power, which are intermittent and depend on weather conditions, nuclear plants provide a consistent and continuous supply of power. This stability is crucial for maintaining grid reliability and ensuring that energy demand is met even when renewable sources are not producing electricity.

  2. Low Carbon Footprint: France’s commitment to nuclear energy has significantly contributed to its low carbon emissions. By relying heavily on nuclear power, France has managed to reduce its greenhouse gas emissions substantially compared to many other countries. This achievement is particularly relevant as Europe strives to meet ambitious climate targets, with debates over a nuclear option in Germany highlighting climate trade-offs, and reduce overall carbon footprints. The low emissions associated with nuclear power make it an important tool for achieving climate goals and transitioning away from fossil fuels.

  3. Energy Security: Nuclear power has played a vital role in France's energy security. The country’s extensive network of nuclear power plants ensures a stable and secure supply of electricity, reducing its dependency on imported energy sources. This energy security is particularly important in the context of global energy market fluctuations and geopolitical uncertainties. France’s experience demonstrates how nuclear energy can contribute to a nation’s energy independence and resilience.

  4. Economic Benefits: The nuclear industry in France also provides significant economic benefits. It supports thousands of jobs in construction, operation, and maintenance of power plants, as well as in the supply chain for nuclear fuel and waste management. Additionally, the stable and relatively low cost of nuclear-generated electricity can contribute to lower energy prices for consumers and businesses, enhancing economic stability.

Germany, in contrast, has been moving away from nuclear energy, particularly following the Fukushima disaster in 2011. The country has committed to phasing out its nuclear reactors by 2022 and focusing on expanding renewable energy sources such as wind and solar power. While Germany's renewable energy transition has made significant strides, it has also faced challenges related to grid stability, as Germany's energy balancing act illustrates for policymakers, energy storage, and maintaining reliable power supplies during periods of low renewable generation.

France’s experience with nuclear energy offers several lessons for Germany and other nations considering their own energy strategies:

  • Balanced Energy Mix: A diverse energy mix that includes nuclear power alongside renewable sources can help ensure a stable and reliable electricity supply, as ongoing discussions about a nuclear resurgence in Germany emphasize for policymakers today. While renewable energy is essential for reducing carbon emissions, it can be intermittent and may require backup from other sources to maintain grid reliability. Nuclear power can complement renewable energy by providing a steady and consistent supply of electricity.

  • Investment in Infrastructure: To maximize the benefits of nuclear energy, investment in infrastructure is crucial. This includes not only the construction and maintenance of power plants but also the development of waste management systems and safety protocols. France’s experience demonstrates the importance of long-term planning and investment to ensure the safe and effective use of nuclear technology.

  • Public Perception and Policy: Public perception of nuclear energy can significantly impact its adoption and deployment, and ongoing Franco-German nuclear disputes show how politics shape outcomes across borders. Transparent communication, rigorous safety standards, and effective waste management are essential for addressing public concerns and building trust in nuclear technology. France’s successful use of nuclear power is partly due to its emphasis on safety and regulatory compliance.

In conclusion, France's experience with nuclear power provides valuable insights into the role that this technology can play in an energy transition. By offering a stable, low-carbon, and reliable source of electricity, nuclear power complements renewable energy sources and supports overall energy security. As Germany and other countries navigate their energy transitions, France's example underscores the importance of a balanced energy mix, robust infrastructure, and effective public engagement in harnessing the benefits of nuclear power while addressing associated challenges, with industry voices such as Eon boss on nuclear debate underscoring the sensitivity of cross-border critiques.

Energy authority clears TEPCO to restart Niigata nuclear plant

TEPCO Kashiwazaki-Kariwa restart plan clears NRA fitness review, anchored by a seven-point safety code, Niigata consent, Fukushima lessons, seismic risk analysis, and upgrades to No. 6 and No. 7 reactors, each rated 1.35 GW.

 

Key Points

TEPCO's plan to restart Kashiwazaki-Kariwa under NRA rules, pending Niigata consent and upgrades to Units 6 and 7.

✅ NRA deems TEPCO fit; legally binding seven-point safety code

✅ Local consent required: Niigata review of evacuation and health impacts

✅ Initial focus on Units 6 and 7; 1.35 GW each, seismic upgrades

 

Tokyo Electric Power Co. cleared a major regulatory hurdle toward restarting a nuclear power plant in Niigata Prefecture, but the utility’s bid to resume its operations still hangs in the balance of a series of political approvals.

The government’s nuclear watchdog concluded Sept. 23 that the utility is fit to operate the plant, based on new legally binding safety rules TEPCO drafted and pledged to follow, even as nuclear projects worldwide mark milestones across different regulatory environments today. If TEPCO is found to be in breach of those regulations, it could be ordered to halt the plant’s operations.

The Nuclear Regulation Authority’s green light now shifts the focus over to whether local governments will agree in the coming months to restart the Kashiwazaki-Kariwa plant.

TEPCO is keen to get the plant back up and running. It has been financially reeling from the closure of its nuclear plants in Fukushima Prefecture following the triple meltdown at the Fukushima No. 1 nuclear plant in 2011 triggered by the earthquake and tsunami disaster.

In parallel, Japan is investing in clean energy innovations such as a large hydrogen system being developed by Toshiba, Tohoku Electric Power and Iwatani.

The company plans to bring the No. 6 and No. 7 reactors back online at the Kashiwazaki-Kariwa nuclear complex, which is among the world’s largest nuclear plants, amid China’s nuclear energy continuing on a steady development track in the region.

The two reactors each boast 1.35 gigawatts in output capacity, while Kenya’s nuclear plant aims to power industry as part of that country’s expansion. They are the newest of the seven reactors there, first put into service between 1996 and 1997.

TEPCO has not revealed specific plans yet on what to do with the older five reactors.

In 2017, the NRA cleared the No. 6 and No. 7 reactors under the tougher new reactor regulations established in 2013 in response to the Fukushima nuclear disaster, while jurisdictions such as Ontario support continued operation at Pickering under strict oversight.

It also closely scrutinized the operator’s ability to run the Niigata Prefecture plant safely, given its history as the entity responsible for the nation’s most serious nuclear accident.

After several rounds of meetings with top TEPCO managers, the NRA managed to hold the utility’s feet to the fire enough to make it pledge, in writing, to abide by a new seven-point safety code for the Kashiwazaki-Kariwa plant.

The creation of the new code, which is legally binding, is meant to hold the company accountable for safety measures at the facility.

“As the top executive, the president of TEPCO will take responsibility for the safety of nuclear power,” one of the points reads. “TEPCO will not put the facility’s economic performance above its safety,” reads another.

The company promised to abide by the points set out in writing during the NRA’s examination of its safety regulations.

TEPCO also vowed to set up a system where the president is directly briefed on risks to the nuclear complex, including the likelihood of earthquakes more powerful than what the plant is designed to withstand. It must also draft safeguard measures to deal with those kinds of earthquakes and confirm whether precautionary steps are in place.

The utility additionally pledged to promptly release public records on the decision-making process concerning crucial matters related to nuclear safety, and to preserve the documents until the facility is decommissioned.

TEPCO plans to complete its work to reinforce the safety of the No. 7 reactor in December. It has not set a definite deadline for similar work for the No. 6 reactor.

To restart the Kashiwazki-Kariwa plant, TEPCO needs to obtain consent from local governments, including the Niigata prefectural government.

The prefectural government is studying the plant’s safety through a panel of experts, which is reviewing whether evacuation plans are adequate as off-limits areas reopen and the health impact on residents from the Fukushima nuclear disaster.

Niigata Governor Hideyo Hanazumi said he will not decide on the restart until the panel completes its review.

The nuclear complex suffered damage, including from fire at an electric transformer, when an earthquake it deemed able to withstand hit in 2007.

The Collapse of Electric Airplane Startup Eviation

Eviation Collapse underscores electric aviation headwinds, from Alice aircraft battery limits to FAA/EASA certification hurdles, funding shortfalls, and leadership instability, reshaping sustainability roadmaps for regional airliners and future zero-emission flight.

 

Key Points

Eviation Collapse is the 2025 shutdown of Eviation Aircraft, revealing battery, certification, and funding hurdles.

✅ Battery energy density limits curtailed Alice's range

✅ FAA/EASA certification timelines delayed commercialization

✅ Funding gaps and leadership churn undermined execution

 

The electric aviation industry was poised to revolutionize the skies through an aviation revolution with startups like Eviation Aircraft leading the charge to bring environmentally friendly, cost-efficient electric airplanes into commercial use. However, in a shocking turn of events, Eviation has faced an abrupt collapse, signaling challenges that may impact the future of electric flight.

Eviation’s Vision and Early Promise

Founded in 2015, Eviation was an ambitious electric airplane startup with the goal of changing the way the world thinks about aviation. The company’s flagship product, the Alice aircraft, was designed to be an all-electric regional airliner capable of carrying up to 9 passengers. With a focus on sustainability, reduced operating costs, and a quieter flight experience, Alice attracted attention as one of the most promising electric aircraft in development.

Eviation’s aircraft was aimed at replacing small, inefficient, and environmentally damaging regional aircraft, reducing emissions in the aviation industry. The startup’s vision was bold: to create an airplane that could offer all the benefits of electric power – lower operating costs, less noise, and a smaller environmental footprint. Their goal was not only to attract major airlines but also to pave the way for a more sustainable future in aviation.

The company’s early success was driven by substantial investments and partnerships. It garnered attention from aviation giants and venture capitalists alike, drawing support for its innovative technology. In fact, in 2019, Eviation secured a deal with the Israeli airline, El Al, for several aircraft, a deal that seemed to promise a bright future for the company.

Challenges in the Electric Aviation Industry

Despite its early successes and strong backing, Eviation faced considerable challenges that eventually contributed to its downfall. The electric aviation sector, as promising as it seemed, has always been riddled with hurdles – from battery technology to regulatory approvals, and compounded by Europe’s EV slump that dampened clean-transport sentiment, the path to producing commercially viable electric airplanes has proven more difficult than initially anticipated.

The first major issue Eviation encountered was the slow development of battery technology. While electric car companies like Tesla were able to scale their operations quickly during the electric vehicle boom due to advancements in battery efficiency, aviation technology faced a more significant obstacle. The energy density required for a plane to fly long distances with sufficient payload was far greater than what existing battery technology could offer. This limitation severely impacted the range of the Alice aircraft, preventing it from meeting the expectations set by its creators.

Another challenge was the lengthy regulatory approval process for electric aircraft. Aviation is one of the most regulated industries in the world, and getting a new aircraft certified for flight takes time and rigorous testing. Although Eviation’s Alice was touted as an innovative leap in aviation technology, the company struggled to navigate the complex process of meeting the safety and operational standards required by aviation authorities, such as the FAA and EASA.

Financial Difficulties and Leadership Changes

As challenges mounted, Eviation’s financial situation became increasingly precarious. The company struggled to secure additional funding to continue its development and scale operations. Investors, once eager to back the promising startup, grew wary as timelines stretched and costs climbed, amid a U.S. EV market share dip in early 2024, tempering enthusiasm. With the electric aviation market still in its early stages, Eviation faced stiff competition from more established players, including large aircraft manufacturers like Boeing and Airbus, who also began to invest heavily in electric and hybrid-electric aircraft technologies.

Leadership instability also played a role in Eviation’s collapse. The company went through several executive changes over a short period, and management’s inability to solidify a clear vision for the future raised concerns among stakeholders. The lack of consistent leadership hindered the company’s ability to make decisions quickly and efficiently, further exacerbating its financial challenges.

The Sudden Collapse

In 2025, Eviation made the difficult decision to shut down its operations. The company announced the closure after failing to secure enough funding to continue its development and meet its ambitious production goals. The sudden collapse of Eviation sent shockwaves through the electric aviation sector, where many had placed their hopes on the startup’s innovative approach to electric flight.

The failure of Eviation has left many questioning the future of electric aviation. While the industry is still in its infancy, Eviation’s downfall serves as a cautionary tale about the challenges of bringing cutting-edge technology to the skies. The ambitious vision of a sustainable, electric future in aviation may still be achievable, but the path to success will require overcoming significant technological, regulatory, and financial obstacles.

What’s Next for Electric Aviation?

Despite Eviation’s collapse, the electric aviation sector is far from dead. Other companies, such as Joby Aviation, Vertical Aerospace, and Ampaire, are continuing to develop electric and hybrid-electric aircraft, building on milestones like Canada’s first commercial electric flight that signal ongoing demand for green alternatives to traditional aviation.

Moreover, major aircraft manufacturers are doubling down on their own electric aircraft projects. Boeing, for example, has launched several initiatives aimed at reducing carbon emissions in aviation, while Harbour Air’s point-to-point e-seaplane flight showcases near-term regional progress, and Airbus is testing a hybrid-electric airliner prototype. The collapse of Eviation may slow down progress, but it is unlikely to derail the broader movement toward electric flight entirely.

The lessons learned from Eviation’s failure will undoubtedly inform the future of the electric aviation sector. Innovation, perseverance, and a steady stream of investment will be critical for the success of future electric aircraft startups, as exemplified by Harbour Air’s research-driven electric aircraft efforts that highlight the value of sustained R&D. While the dream of electric planes may have suffered a setback, the long-term vision of cleaner, more sustainable aviation is still alive.

Don't be taken in by scammers threatening to shut off electricity: Manitoba Hydro

Manitoba Hydro Phone Scam targets small businesses with disconnection threats, prepaid card payments, caller ID spoofing, phishing texts, and door-to-door fraud; hang up, verify your account directly, and never share banking information.

 

Key Points

A scam where callers threaten disconnection and demand prepaid cards; verify account status directly with Manitoba Hydro.

✅ Hang up and call Manitoba Hydro at 1-888-624-9376 to verify.

✅ Never pay by prepaid cards, gift cards, or crypto.

✅ Hydro will not cut power on one-hour notice.

 

Manitoba Hydro is warning customers, particularly small business owners, to be wary of high-pressure scammers, as Ontario utilities warn of scams in other provinces, threatening to shut off their electricity.

The callers demand the customer to make immediate payment by a prepaid card. Often, the calls are made in the middle of the day at a busy time, frightening the customer with aggressive threats about disconnection, as hydro disconnections have made headlines elsewhere, says hydro spokesman Bruce Owen.

"They tell them 'we have a truck on the way to cut off your power. If you don't pay in the next hour you're out of luck,'" he said.

"And because these folks have inventory in freezers and they have customers … they're willing to fork over several hundred or even several thousand dollars on a prepaid card to somebody they don't know to keep the lights on."

Maybe the business owners can't recall, with everything happening, including discussions about Hydro One peak rates in Ontario, if they've made their payments on time. They start second-guessing and believing the person on the other line, Owen says.

And they worry about losing thousands of dollars in business if they lose power. So they're more than willing to run out to a store, buy a prepaid debit card and provide the number to the caller.

"Their goal is to manipulate you into sending money before you figure out it's a scam," said Chris McColm, hydro's security and investigations supervisor. "These people are crooks and you should hang up on them."

For any customers that are in arrears, hydro will work with them to resolve the issue, Owen said.

"We do not have to take that extreme measure of cutting off or disconnecting anybody. That's not the business we're in — we don't strong arm people that way," he said.

"Anybody who's threatening to cut off your power with an hour or half-an-hour notice, well it's it's no better than someone waiting around the corner, waiting the club you over the head in the dark of night. That's what they are."

 

Fraud reports soar

The power utility has recorded a nearly-300 per cent jump in the number of fraud-related complaints this year over 2017. There have been 862 phone, text and e-mail scams and that could still go much higher.

The current statistics from 2018 have only calculated up to Oct. 31. In 2017, there were 221.

That jump in numbers doesn't necessarily mean there are more scammers out there.

It could simply mean people are finally getting wise to fraudsters and reporting it more, Owen says.

"At the same token, we don't hear of everybody who's been taking advantage of because once they've found out that they've been hoodwinked they don't want to tell anybody because they're so embarrassed," he said.

"These scammers can be very convincing and anyone can be victimized," McColm said.

If you are able to think clearly when some high-pressure caller gets you on the line, Owen suggests asking a few simple questions to challenge their legitimacy:

  • What street am I on?
  • What does my business look like? 
  • What's the weather outside right now?

Phone scammers can falsify their caller ID information to make it appear they're calling from a local number, but what you'll find is most of them aren't in Winnipeg or Manitoba and likely not even this country or continent, Owen says.

The key to being safe is simply to never give out banking information, Owen says. It's a message that has been stressed for years and 80-90 per cent of people understand it, but it's that other 10-20 per cent that are still being victimized.And it's not just phone calls. Many other fraud-related complaints to Manitoba Hydro this year concerned unsolicited text messages to customers saying they had been overbilled, or faced retroactive charges elsewhere, and were eligible for a refund.

This scam is also aimed at getting a customer's personal banking information, under the guise of having money put back into their account.

Also, many people, especially seniors living alone, continue to be targeted by aggressive door-to-door fraudsters, and cases like the electricity theft ring in Montreal underscore the risks, McColm says. However, he adds, hydro employees always display photo ID and will never demand to come into a home. 

If you're unsure whether a phone call, text or email is real or a scam, contact Manitoba Hydro at 1-888-624-9376.

UK electricity and gas networks making ‘unjustified’ profits

UK Energy Network Profits are under scrutiny as Ofgem price controls, Citizens Advice claims, and National Grid margins spark debate over monopolies, allowed returns, consumer bills, rebates, and future investment under tougher regulation.

 

Key Points

UK Energy Network Profits are returns set by Ofgem for regulated grid operators, shaping consumer bills and investment

✅ Ofgem sets allowed returns for monopoly networks via price controls

✅ Dispute over interest rates, bond yields, and risk premiums

✅ Reforms proposed: shorter controls, tougher investor incentives

 

Companies that run Britain’s electricity and gas networks, including National Grid, are making “eye-watering” profits at the expense of households, according to a well-known consumer group.

Citizens Advice believes £7.5bn in “unjustified” profits should be returned to consumers who pay for network costs via their electricity and gas bills, with parallels seen in a deferred BC Hydro costs report abroad, although its figures have been contested by the energy industry and regulator.

Ownership of electricity and gas networks came under the spotlight in the run-up to June’s general election, after the Labour party said in its manifesto it would bring both national and regional grid infrastructure to back into public ownership, amid wider debates about grid privatization concerns elsewhere, over time.

Electricity sector privatisation began in 1990 and the gas industry was privatised in 1986. Energy network companies — which own and operate the cables and wires that help deliver electricity and gas to homes and businesses — are in effect monopolies that are regulated by Ofgem. Ofgem evaluates what their costs, including the cost of capital to finance investments, might be over an eight-year “price control” period, similar to determinations like the OEB decision on Hydro One rates in Ontario, Canada. Citizens Advice claims many of the regulator’s calculations for the most recent price control went “considerably in networks’ financial favour”.

It believes assumptions Ofgem made about factors such as the future path of interest rates and returns on government bonds were too generous, with international contrasts like power theft challenges in India illustrating different risk contexts, as was the regulator’s assessment of the risk associated with operating a network company. 

These “generous” assumptions will lead to network companies making average profit margins of 19 per cent and an average return of 10 per cent for their investors at the expense of consumers, Citizens Advice claims in a report published on Wednesday, which recommends a shorter price control period to allow for more accurate forecasting.

“Decisions made by Ofgem have allowed gas and electricity network companies to make sky-high profits that we’ve found are not justified by their performance,” said Gillian Guy, chief executive of Citizens Advice. Ofgem defended its regulatory regime, saying it helped to cut costs, improve reliability and customer satisfaction. 

“Ofgem has already cut costs to consumers by 6 per cent in the current price control and secured a rebate of over £4.5bn from network companies and is engaging with the industry to deliver further savings, with some regions seeing Ontario electricity rate reductions for businesses as well,” said Dermot Nolan, chief executive of the energy regulator.

Mr Nolan insisted the next price controls would be “tougher for investors”. The current price controls for the gas and electricity transmission networks, plus gas distribution, run until 2021 and until 2023 for local electricity distribution networks.

“While we don’t agree with its modelling and the figures it has produced, the Citizens Advice report raises some important issues about network regulation which will be addressed in the next control,” Mr Nolan said.

The Energy Networks Association, a trade body, refuted the claims of Citizens Advice, insisting that costs had fallen by 17 per cent in real terms since privatisation. The current regulatory framework was established after a public consultation, it said, adding that today’s report repeated several old claims that had previously been rejected by the Competition and Markets Authority.

“Our energy networks are among the most reliable and lowest cost in the world and their performance has never been better. In the next six years energy network companies are forecasted to deliver £45bn of investment in the UK economy,” a spokesman for the networks association added. National Grid said that since 2013 it had generated savings of £460m for bill payers.

Renewable growth drives common goals for electricity networks across the globe

Energy Transition Grid Reforms address transmission capacity, interconnection, congestion management, and flexibility markets, enabling renewable integration and grid stability while optimizing network charges and access in Australia, Ireland, and Great Britain.

 

Key Points

Measures to expand transmission, boost flexibility, and manage congestion for reliable, low-carbon electricity systems.

✅ Transmission upgrades and interconnectors ease congestion

✅ Flexible markets, DER, and storage bolster grid stability

✅ Evolving network charges and access incentivize siting

 

Electricity networks globally are experiencing significant increases in the volume of renewable capacity as countries seek to decarbonise their power sectors, even as clean energy's 'dirty secret' highlights integration trade-offs, without impacting the security of supply. The scale of this change is creating new challenges for power networks and those responsible for keeping the lights on.

The latest insight paper from Cornwall Insight – Market design amidst global energy transition – looks into this issue. It examines the outlook for transmission networks, and how legacy design and policies are supporting decarbonisation, aligning with IRENA findings on renewables and shaping the system. The paper focuses on three key markets; Australia, Ireland and Great Britain (GB).

Australia's main priority is to enhance transmission capacity and network efficiency; as concerns over excess solar risking blackouts grow in distribution networks, without this, the transmission system will be a barrier to growth for decentralised flexibility and renewables. In contrast, GB and Ireland benefit from interconnection with other national markets. This provides them with additional levers that can be pulled to manage system security and supply. However, they are still trying to hone and optimise network flexibility in light of steepening decarbonisation objectives.

Unsurprisingly, renewable energy resources have been growing in all three markets, with Ireland regarded as a leader in grid integration, with this expected to continue for the foreseeable future. Many of these projects are often located in places where network infrastructure is not as well developed, creating pressure on system operation as a result.

In all three markets, unit charges are rising, driven by a reduced charging base as decentralised energy grows quickly. This combination of changes is leading to network congestion, a challenge mirrored by the US grid overhaul for renewables underway, as transmission network development struggles to keep up, and flexibility markets are being optimised and changed.

In summary, reforms are on-going in each jurisdiction to accommodate the rapid physical transformation of the generation mix. Each has its objectives and tensions which are reflective of wider global reform programmes being undertaken in most developed, liberalised and decarbonising energy markets.

Gareth Miller, CEO of Cornwall Insight, said: “Despite differences in market design and characteristics, all three markets are grappling with similar issues, that comes from committing to deep decarbonisation. This includes the most appropriate methods for charging for networks, managing access to them and dealing with issues such as network congestion and constraint.

“In all three countries, renewable projects are often placed in isolated locations, as seen in Scotland where more pylons are needed to keep the lights on, away from the traditional infrastructure that is closer to demand. However, as renewable growth is set to continue, the networks will need to transition from being demand-centric to more supply orientated.

“Both system operators and stakeholders will need to continually evaluate their market structures and designs to alleviate issues surrounding locational congestion and grid stability. Each market is at very different stages in the process in trying to improve any problems implementing solutions to allow for higher efficiencies in renewable energy integration.

“It is uncertain whether any of the proposed changes will fundamentally resolve the issues that come with increased renewables on the system. However, despite marked differences, they certainly could all learn from each other and elements of their network arrangements, as well as from US decarbonisation strategies research.”
