The province of Alberta deregulated its retail energy markets in 2001. It was "certainly trying times" for ENMAX Energy, an energy retailer in Alberta, Canada, according to Paul Gelleta, operations manager for ENMAX's commercial and institutional (C&I) markets.

The retailer faced a dilemma: It had a strong presence in the electricity market. But "more and more of our customers wanted a total energy solution that included natural gas," explains Gelleta.

ENMAX had to decide what to do: either continue to just supply electricity or enter the natural gas market. The decision was serious; Gelleta says studies showed if ENMAX didn't enter the natural gas market, it could start losing its current electricity customers. "That would limit our growth," he says.

ENMAX's competitors were compounding the problem. "Their solutions were more flexible and complete than ours," he recalls. "ENMAX's legacy systems were struggling to do the job, in particular with the complexities of the contracts signed for the deregulated C&I market," adds Kate Joslyn, president and CEO of Cognera, ENMAX's service provider. Somehow the energy retailer had to transform its legacy systems to work in a deregulated environment. It needed a new solution... immediately.

The bottom line: "We were concerned we would lose customers if we didn't enhance both our products and our service offerings," says Gelleta.

The energy retailer put together a detailed business case analysis to determine what to do. The analysis came up with four options:

1. Do nothing. "This wasn't an option because we knew we would have challenges in retaining customers. And we would have greater difficulty gaining new customers," says Gelleta. But this option had one benefit: further investment would be minimal.

2. Build capability. ENMAX realized its customer base was becoming more sophisticated; the Albertans wanted not only electricity and gas but also the data around it. "They wanted the data to manage their energy needs and reduce their overall costs," explains Gelleta.

This option had some downsides. ENMAX would have to build an in-house billing and reporting system to provide its customers with the data they wanted. "It would have been a struggle to convert our existing legacy system to do that," Gelleta reports. ENMAX had a sophisticated billing system for electricity, but it wouldn't work for natural gas without a large investment, he pointed out.

3. Migrate C&I customers to a service provider on a needs basis. ENMAX would only outsource its solution for customers that were looking for enhanced products and services. This solution presented other difficulties with respect to internal reporting and a need to service essentially the same segment of customers using two different systems.

4. Migrate all C&I customers to a single service provider. This had a huge advantage: all the customers would be in one place.

ENMAX looked at various providers with a history of successful electricity and natural gas billing. It discovered the market mirrored its situation. Many had electricity capabilities and were interested in getting into natural gas. Only one - Cognera - had both. "It was a no-brainer selecting our outsourcing partner," says Gelleta. "Our real decision was determining what to outsource."

ENMAX signed its first deal with Cognera in 2003.

Since the competitive situation was heating up, the two partners worked together for a year with just a letter of intent. At the outset, they piped in the trust on which they built their relationship.

Enron was actually the glue that held the partners together in the beginning. Enron Canada went bankrupt and ENMAX purchased its contracts and billing system; a few Enron employees joined ENMAX as part of the purchase. At the same time, a number of Cognera's senior management had worked for Enron.

Initially, the partners just worked on the natural gas piece. "We moved our natural gas customers to Cognera first because that was our most pressing need," reports Gelleta. "There were natural gas market changes coming down the pipe, and modifying the largely prototype billing system we inherited as part of the Enron deal would have kept us in the market from a compliance standpoint; but it was far from where we ultimately wanted to be with respect to our products and services."

ENMAX initially gave them small jobs to do. "They did a bang-up job. The scope continued to grow from that," says Gelleta. Soon ENMAX moved its electricity clients, too. "It was a gradual process," continues Joslyn. "ENMAX selected the strategic accounts it needed to move quickly." Joslyn says the transition was "an organized, methodical process." Gelleta adds "it was collaborative."

Implementing these changes was as tricky as working on a high voltage line because ENMAX would permit no customer interruptions. "We worked through this with a collaborative and iterative approach involving key members of both teams to ensure efficient decision making," says Gelleta.

The challenge was not transitioning to outsourcing but the ability to extract the requisite data from the ENMAX legacy system. "We used the migration period to validate historical data and billing requirements to ensure we sent accurate data to Cognera," says Gelleta.

Gelleta explains the complete data set Cognera required for the migration was spread across multiple systems on a variety of outdated platforms. To make this work smoothly, Cognera had to develop customized data input processes to handle "the vagaries in the data outputs," continues Gelleta. Then, they had to merge the data from different sources. Cognera developed customer data load scripts to ensure the supplier loaded all information accurately.

"It was difficult to ensure the products we were invoicing were correct because we weren't sure if we were invoicing them correctly in the original system," continues Gelleta. Cognera's business analysts worked with ENMAX to review all its contracts to ensure the partners implemented each contract as originally intended. "This detailed review uncovered several historical anomalies, which we corrected," reports Gelleta.

The initial contract only covered natural gas billing. The relationship worked so well ENMAX increased the scope, adding wholesale and retail electricity billing and settlement.

Gelleta says at the outset there was an internal struggle. Some senior execs/managers and numerous employees were uncomfortable that ENMAX was losing control over its data and customers because it outsourced. "It took two years to work through that," says Gelleta. "Fairly quickly and continually, our employees realized Cognera's business practices, platform, and reporting capabilities gave us better customer information than our internal systems ever did. That put them at ease," he reports.

In fact, once ENMAX employees saw what Cognera could deliver, "more and more people got excited about it," says Gelleta. "They said, 'Holy smokes. Wow! We can't believe we can get that.'"

Today, Gelleta says the two partners work so well many employees at ENMAX don't feel like this is an outsourced relationship. "Cognera is an extension of our business," says Gelleta.

Once the employees were on board, the word started seeping into the marketplace. "Our customers started hearing about our capabilities and wanted to join this program. Our new customer drive took off from there," says Gelleta.

The sales cycle for a natural gas and electricity contract can take months. But when customers sign up, they want the service to start immediately. "Quite often, we try to enroll new customers at the beginning of the month. But they don't receive their contracts to enroll until the last day of the prior month," Gelleta explains. That creates a crunch for Cognera. "The staff puts in the extra hours - both on weekends or late a night - to enter those contracts so we can enroll those customers at the start of the next month," says Gelleta. "Cognera always goes the extra mile for us."

"We knew they would take a partnership approach when we received their response package," says Gelleta. "From the first day we worked together, this has been an open relationship. It's never felt like it's an outsourcing relationship. We view Cognera as an extension of our operation."

Joslyn says this relationship works because it's always been "a win-win situation for both parties." She says Cognera never acts "to win at the expense of our clients." She says the company views decisions from this starting point: "How do we create value for our buyers and make money at the same time?" She says "a lot of dialog" is the only way to make this happen.

She also makes sure she communicates this message to her entire organization. "We drive home to our staff that our customers have to be successful," she says.

Gelleta says both parties "rarely touch the contract to look at the specific terms and conditions." Since both parties "are working towards bettering the business, the big picture just takes care of itself," he says.

ENMAX and Cognera have instituted an ongoing business practice that keeps the relationship fresh: they oversee and critique each other's work. "This is not to challenge the other party. We only do this to better the overall solution," says Gelleta.

He says both parties can count on each other to do what each brought to the relationship. "If we think we can improve something, we send in a request. They look at it and decide on the best quality and most cost-effective solution. Then we move forward," he notes.

Joslyn says Cognera strives to be flexible. "Business needs evolve. So do business requirements. We know we have to be adaptable," she explains.

"When things aren't going quite right, we have an open dialog," says Gelleta. The two partners also discuss "new things coming down the pipeline." Communication is easy "because there isn't a long list of protocols to go through," says Gelleta. Members of the ENMAX team know their counterparts at Cognera and feel comfortable approaching them.

The two partners meet weekly to discuss operational priorities, issues, and any changes on the horizon that require immediate attention. The management teams also have regular breakfast meetings to discuss future direction and opportunities.

Outsourcing solved the immediate need to add natural gas to the mix. Gelleta estimates it would have taken ENMAX two years to modify its existing system; Cognera had its system up and running in six months.

Getting this done early had a bottom-line benefit. "In 2003 the market was still immature. We had plenty of opportunity to pounce, which gave us first-mover advantage," says Gelleta.

The arrangement also allowed ENMAX to retain its current customers and grow its business. Gelleta says in 2007 the company grew 10 percent over 2006. "We did this because we quickly gained improved capabilities," he explains. The new products it could now offer allowed ENMAX "to become the high-value provider in the marketplace."

Gelleta says the retailer is also the low-cost provider, aided by operational savings from outsourcing. "We know our solution has to be affordable because we know margins are tight for all retailers," says Joslyn. For the first time in the new deregulated environment, ENMAX was able to compete by offering "superior products and services." Being able to supply the data consumers want has allowed them "to utilize our system to create their own innovative solutions," says Gelleta.

Cognera's data "facilitates our decision-making process," continues Gelleta. The retailer can now access 75 Web reports pertaining to its operations, finances, and energy consumption. Its customers can also view a subset of these reports. "Our customers say this ability provides superior customer service, which gives us a competitive advantage."

ENMAX is now more fleet of foot. It would take months to years to make a change in its old legacy system. Now, Cognera can make changes in weeks. The ability to change quickly also helps ENMAX stay current "with rapid regulatory change," says Gelleta. In addition, system enhancements "cost magnitudes less than what we would have paid to alter our legacy system."

Another advantage: Gelleta says the Cognera system requires a minimal learning curve, as it was designed for the deregulated market, our business and with flexibility, as opposed to modified from something that had a similar but different purpose.

Updated Germany hydrogen strategy sees heavy reliance on imported fuel

Germany Hydrogen Import Strategy outlines reliance on green hydrogen imports, expanded electrolysis capacity, IPCEI-funded pipelines, and industrial decarbonization for steel and chemicals to reach climate-neutral goals by 2045, meeting 2030 demand of 95-130 TWh.

 

Key Points

A plan to import 50-70% of hydrogen by 2030, backing green hydrogen, electrolysis, pipelines, and decarbonization.

✅ Imports cover 50-70% of 2030 hydrogen demand

✅ 10 GW electrolysis target with state aid and IPCEI

✅ 1,800 km H2 pipelines to link hubs by 2030

 

Germany will have to import up to 70% of its hydrogen demand in the future as Europe's largest economy aims to become climate-neutral by 2045, an updated government strategy published on Wednesday showed.

The German cabinet approved a new hydrogen strategy, setting guidelines for hydrogen production, transport infrastructure and market plans.

Germany is seeking to expand reliance on hydrogen as a future energy source to bolster energy resilience and cut greenhouse emissions for highly polluting industrial sectors that cannot be electrified such as steel and chemicals and cut dependency on imported fossil fuel.

Produced using solar and wind power, green hydrogen is a pillar of Berlin's plan to build a sustainable electric planet and transition away from fossil fuels.

But even with doubling the country's domestic electrolysis capacity target for 2030 to at least 10 gigawatts (GW), Germany will need to import around 50% to 70% of its hydrogen demand, forecast at 95 to 130 TWh in 2030, the strategy showed.

"A domestic supply that fully covers demand does not make economic sense or serve the transformation processes resulting from the energy transition and the broader global energy transition overall," the document said.

The strategy underscores the importance of diversifying future hydrogen sources, including potential partners such as Canada's clean hydrogen sector, but the government is working on a separate strategy for hydrogen imports whose exact date is not clear, a spokesperson for the economy ministry said.

"Instead of relying on domestic potential for the production of green hydrogen, the federal government's strategy is primarily aimed at imports by ship," Simone Peter, the head of Germany's renewable energy association, said.

Under the strategy, state aid is expected to be approved for around 2.5 GW of electrolysis projects in Germany this year and the government will earmark 700 million euros ($775 million) for hydrogen research to optimise production methods, research minister Bettina Stark-Watzinger said.

But Germany's limited renewable energy space will make it heavily dependent on imported hydrogen from emerging export hubs such as Abu Dhabi hydrogen exports gaining scale, experts say.

"Germany is a densely populated country. We simply need space for wind and photovoltaic to be able to produce the hydrogen," Philipp Heilmaier, an energy transition researcher at Germany energy agency, told Reuters.

The strategy allows the usage of hydrogen produced through fossil energy sources preferably if the carbon is split off, but said direct government subsidies would be limited to green hydrogen.

Funds for launching a hydrogen network with more than 1,800 km of pipelines in Germany are expected to flow by 2027/2028 through the bloc's Important Projects of Common European Interest (IPCEI) financing scheme, as the EU plans to double electricity use by 2050 could raise future demand, with the goal of connecting all major generation, import and storage centres to customers by 2030.

Transport Minister Volker Wissing said his ministry was working on plans for a network of hydrogen filling stations and for renewable fuel subsidies.

Environmental groups said the strategy lacked binding sustainability criteria and restriction on using hydrogen for sectors that cannot be electrified instead of using it for private heating or in cars, calling for a plan to eventually phase-out blue hydrogen which is produced from natural gas.

Germany has already signed several hydrogen cooperation agreements with countries such as clean energy partnership with Canada and Norway, United Arab Emirates and Australia.

Europe's Thirst for Electricity Spurs Nordic Grid Blockade

Nordic Power Grid Dispute highlights cross-border interconnector congestion, curtailed exports and imports, hydropower priorities, winter demand spikes, rising spot prices, and transmission grid security amid decarbonization efforts across Sweden, Norway, Finland, and Denmark.

 

Key Points

A clash over interconnectors and capacity cuts reshaping trade, prices, and reliability in the Nordic power market.

✅ Sweden cuts interconnector capacity to protect grid stability

✅ Norway prioritizes higher-priced exports via new cables

✅ Finland and Denmark seek EU action on capacity curtailments

 

A spat over electricity supplies is heating up in northern Europe. Sweden is blocking Norway from using its grids to transfer power from producers throughout the region. That’s angered Norway, which in turn has cut flows to its Nordic neighbor.

The dispute has built up around the use of cross-border power cables, which are a key part of Europe’s plans to decarbonize since they give adjacent countries access to low-carbon resources such as wind or hydropower. The electricity flows to wherever prices are higher, informed by how electricity is priced across Europe, without interference from grid operators -- but in the event of a supply squeeze, flows can be stopped.

Sweden moved to safeguard the security of its grid after Norway started increasing electricity exports through huge new cables to Germany and the U.K. Those exports at times have drawn energy away from Sweden, resulting in the country’s system operator cutting capacity at its Nordic borders, preventing exports but also hindering imports, which it relies on to handle demand spikes during winter.

“This is not a good situation in the long run,” Christian Holtz, a energy market consultant for Merlin & Metis AB.

Norway hit back last week by cutting flows to Sweden, this will prioritize better paying customers in Europe, amid Irish price spikes that highlight dispatchable shortages, giving them access to its vast hydro resources at the expense of its Nordic neighbors. 

By partially closing its borders Sweden can’t access imports either, which it relies on to handle demand spikes during the coldest days of the winter. 

In Denmark, unusual summer and autumn winds have at times delivered extraordinarily low electricity prices that ripple through regional markets.

The Swedish grid manager Svenska Kraftnat has reduced export capacity at cables across its borders by as much as half this year to keep operations secure. Finland and Denmark rely on imports too and the cuts will come at a cost for millions of homes and industries across the four nations already contending with record electricity rates this year. 

Finland and Denmark want the European Union to end the exemption to regulations that make such reductions possible in the first place, as Europe is losing nuclear power and facing tighter supply.

“Imports from our neighboring countries ensure adequacy at times of peak consumption,” said Reima Paivinen, head of operation at the Finland’s Fingrid. “The recent surge in electricity prices throughout Europe does not directly affect the adequacy of electricity, but prices may rise dramatically for short periods.”

Svenska Kraftnat says it’s not political -- it has no choice but to cut capacity until its old grids are expanded to handle the new direction of flows, a challenge mirrored by grid expansion woes in Germany that slow integration. That could take at least until 2030 to complete, it said earlier this year. At the same time, Norway halving available export capacity to about 1,200 megawatts will increase risk of shortages. 

“If we need more we will have to count on imports from other countries,” said Erik Ek, head of strategic operation at Svenska Kraftnat. “If that is not available, we will have to disconnect users the day it gets cold.”

Sunrun and Tesla Unveil Texas Power Plant

Sunrun-Tesla Virtual Power Plant Texas leverages residential solar, Tesla Powerwall battery storage, and ERCOT demand response to enhance grid resilience, cut emissions, and supply backup power via a coordinated distributed energy resources network.

 

Key Points

A Texas VPP using residential solar and Tesla Powerwall to aid ERCOT with grid services resilience, and less emissions.

✅ Aggregates Powerwall storage for ERCOT demand response.

✅ Enhances grid reliability with distributed energy resources.

✅ Cuts emissions by shifting solar to peak and outage periods.

 

In a significant development for renewable energy and grid resilience, Sunrun and Tesla have announced a groundbreaking partnership to establish a distributed power plant in Texas. This collaboration represents a major step forward in harnessing solar energy and battery storage, with advances in affordable solar batteries helping to create a more reliable and sustainable power system. The initiative aims to address the growing demand for clean energy solutions while enhancing grid stability and resilience in one of the largest and most energy-dependent states in the U.S.

The new distributed power plant, a joint venture between Sunrun, a leading residential solar provider, and Tesla, renowned for its advanced battery technology and electric vehicles, will leverage the strengths of both companies to transform how energy is generated and used. The project will deploy Tesla's Powerwall battery systems alongside Sunrun's solar panels to create a network of interconnected residential energy storage units. This network will function as a virtual power plant, aligned with emerging peer-to-peer energy sharing models that are capable of providing electricity back to the grid during periods of high demand or outages.

Texas, with its vast and growing population, has faced significant energy challenges in recent years. The state’s power grid, managed by the Electric Reliability Council of Texas (ERCOT), has experienced strain during extreme weather events and high demand periods, and instances of Texas wind curtailment during grid stress, leading to concerns about reliability and stability. The partnership between Sunrun and Tesla seeks to address these concerns by introducing a more flexible and resilient energy solution.

The distributed power plant will consist of thousands of residential solar installations, each equipped with Tesla Powerwall batteries, reflecting the broader trend of pairing storage with solar across the U.S. as it scales. These batteries store excess solar energy generated during the day and release it when needed, such as during peak demand times or power outages. By connecting these systems through advanced software, the project will create a coordinated network of distributed energy resources that can respond dynamically to fluctuations in energy supply and demand.

One of the key benefits of this distributed approach is its ability to enhance grid reliability. Traditional power plants are centralized and can be vulnerable to disruptions, whether from extreme weather, technical failures, or other issues. In contrast, a distributed power plant spreads the generation and storage capacity across numerous locations, a principle echoed by renewable power developers pursuing multi-resource projects today, reducing the risk of widespread outages and increasing the overall resilience of the power grid.

Additionally, the project will contribute to the reduction of greenhouse gas emissions. By increasing the use of solar energy and reducing reliance on fossil fuels, and amid ongoing work to improve solar and wind technologies, the distributed power plant supports Texas’s climate goals and contributes to broader efforts to combat climate change. The integration of renewable energy sources into the grid helps to decrease carbon emissions and promote a cleaner, more sustainable energy system.

The partnership between Sunrun and Tesla also underscores the growing role of technology in transforming the energy landscape. Tesla's Powerwall battery systems represent some of the most advanced energy storage technology available, and amid record solar and storage growth nationwide this decade they showcase the capability to store and manage energy efficiently. Sunrun’s expertise in residential solar installations complements this technology, creating a powerful combination that leverages the latest advancements in clean energy.

The project is expected to deliver several benefits to both individual homeowners and the broader community. Homeowners who participate in the program will have access to solar energy and battery storage at reduced costs, thanks to the economies of scale and innovative financing options provided by Sunrun and Tesla. Additionally, they will have the added security of backup power during outages, contributing to greater energy independence and resilience.

For the broader community, the distributed power plant offers a more reliable and sustainable energy system. The ability to generate and store energy at the residential level reduces the strain on traditional power plants and enhances the overall stability of the grid. Furthermore, the project will contribute to local job creation, as the installation and maintenance of solar panels and battery systems require skilled workers.

As the project moves forward, Sunrun and Tesla will work closely with local stakeholders, regulators, and utility providers to ensure the successful implementation and integration of the distributed power plant. Collaboration with these parties will be essential to addressing any regulatory, technical, or logistical challenges and ensuring that the project delivers its intended benefits.

In conclusion, the partnership between Sunrun and Tesla to create a distributed power plant in Texas represents a significant advancement in clean energy technology and grid resilience. By combining solar power with advanced battery storage, the project aims to enhance grid stability, reduce emissions, and provide reliable energy solutions for homeowners. As Texas continues to face energy challenges, this innovative initiative offers a promising model for the future of distributed energy and highlights the potential for technology-driven solutions to address pressing environmental and infrastructure issues.

Hydro-Quebec begins talks for $185-billion strategy to wean the province off fossil fuels

Hydro-Québec $185-Billion Clean Energy Plan accelerates hydroelectric upgrades, wind power expansion, solar and battery storage, pumped storage, and 5,000 km transmission lines to decarbonize Quebec, boost grid resilience, and attract bond financing and Indigenous partnerships.

 

Key Points

Plan to grow renewables, harden the grid, and fund Quebec's decarbonization with major investments.

✅ $110B new generation, $50B grid resilience by 2035

✅ Triple wind, add solar, batteries, and pumped storage

✅ 5,000 km lines, bond financing, Indigenous partnerships

 

Hydro-Québec is in the preliminary stages of dialogue with various financiers and potential collaborators to strategize the implementation of a $185-billion initiative aimed at transitioning Quebec away from fossil fuel dependency.

As the leading hydroelectric power producer in Canada, Hydro-Québec is set to allocate up to $110 billion by 2035 towards the development of new clean energy facilities, building on its hydropower capacity expansion in recent years, with an additional $50 billion dedicated to enhancing the resilience of its power grid, as revealed in a strategy announced last November. The remainder of the projected expenditure will cover operational costs.

This ambitious initiative has garnered significant interest from the financial sector, with the province's recent electricity for industrial projects also drawing attention, as noted by CEO Michael Sabia during a conference call with journalists where the utility's annual financial outcomes were discussed. Sabia reported receiving various proposals to fund the initiative, though specific partners were not disclosed. He expressed confidence in securing the necessary capital for the project's success.

Sabia highlighted three immediate strategies to increase power output: identifying new sites for hydroelectric projects while upgrading turbines at existing facilities, such as the Carillon Generating Station upgrade now underway for enhanced efficiency, expanding wind energy production threefold, and promoting energy conservation among consumers to optimize current power usage.

Additionally, Hydro-Québec aims to augment its solar and battery energy production and is planning to establish a pumped-storage hydroelectric plant to support peak demand periods. The utility also intends to construct 5,000 kilometers of new transmission lines, address Quebec-to-U.S. transmission constraints where feasible, and is set to double its capital expenditure to $16 billion annually, a significant increase from the investment levels during the James Bay hydropower project construction in the 1970s and 1980s.

To fund part of this expansive plan, Hydro-Québec will continue to access the bond market, having issued $3.7 billion in notes to investors last year despite facing several operational hurdles due to adverse weather conditions.

For the year 2023, Hydro-Québec reported a net income of $3.3 billion, marking a 28% decrease from the previous year's record of $4.56 billion. Factors such as insufficient snow cover, reduced spring runoff, and higher temperatures resulted in lower water levels in reservoirs, leading to a reduction in power exports and a $547-million decrease in external market sales compared to the previous year.

The utility experienced its lowest export volume in a decade but managed to leverage hedging strategies to secure 10.3 cents per kWh for exported power to markets including New Brunswick via recent NB Power agreements that expand interprovincial deliveries, nearly twice the average market rate, through forward contracts that cover up to half of its export volume for about a year in advance.

The success of Sabia's plan will partly depend on the cooperation of First Nations communities, as the proposed infrastructure developments are likely to traverse their ancestral territories. Relationships with some communities are currently tense, exemplified by the Innu of Labrador's $4-billion lawsuit against Hydro-Québec for damages related to land flooding for reservoir construction, and broader regional tensions in Newfoundland and Labrador that persist in the power sector.

Sabia has committed to involving First Nations and Inuit communities as partners in clean energy ventures, offering them ongoing financial benefits rather than one-off settlements, a principle he refers to as "economic reconciliation."

Recently, the Quebec government reached an agreement with the Innu of Pessamit, pledging $45 million to support local community development. This agreement outlines solutions for managing a nearby hydropower reservoir, such as the La Romaine complex in the region, and includes commitments for wind energy development.

Sabia is optimistic about building stronger, more positive relationships with various Indigenous communities, anticipating significant progress in the coming months and viewing this year as a potential milestone in transforming these relationships for the better.

End of an Era: UK's Last Coal Power Station Goes Offline

UK Coal-Free Energy Transition highlights the West Burton A closure, accelerating renewable energy, wind, solar, nuclear, energy storage, smart grid upgrades, decarbonization, and net-zero goals while ensuring reliability, affordability, and a just transition for workers.

 

Key Points

A nationwide shift from coal power to renewables, storage, and nuclear to meet net-zero while maintaining reliability.

✅ West Burton A closure ends UK coal-fired generation

✅ Wind, solar, nuclear, storage strengthen grid resilience

✅ Government backs a just transition and worker retraining

 

The United Kingdom marks a historic turning point in its energy transition with the closure of the West Burton A Power Station in Nottinghamshire. This coal-fired power plant, once a symbol of the nation's industrial might, has now delivered its final watts of electricity to the grid, signalling the end of coal power generation in the UK.


A Landmark Shift Towards Clean Energy

The closure of West Burton A reflects a dramatic shift in the UK's energy landscape. Coal, the backbone of the UK's power generation for decades, is being phased out in favour of renewable energy sources like wind, solar, and nuclear. This transition aligns with the UK's ambitious net-zero emissions target, which aims to radically decarbonize the country's economy by 2050, though progress can falter, as when low-carbon generation stalled in 2019 amid changing market conditions.


Changing Energy Landscape

In the past, coal-fired power plants provided reliable, on-demand power. However, growing awareness of their significant environmental impact, particularly their contribution to climate change,  has accelerated the move away from coal. The UK government has set clear targets for eliminating coal power generation, and the industry has seen a steady decline as the share of coal fell to record lows in the electricity system.


Renewables Fill the Gap

The remarkable growth of renewable energy sources has enabled the transition away from coal. Wind and solar power, in particular, have experienced rapid development and falling costs, and in 2016 wind generated more electricity than coal for the first time. The UK now boasts substantial offshore and onshore wind farms and extensive solar installations. Additionally, investments in nuclear power and emerging energy storage technologies are increasing the reliability and diversity of the UK's power grid.


Economic and Social Impacts

The closure of the last coal-fired power station carries both economic and social impacts. While this change represents a victory for environmentalists, marked by milestones like a full week without coal power in Britain, the end of coal mining and power generation will lead to job losses in communities traditionally reliant on these industries.  The government has committed to supporting affected regions and facilitating a "just transition" for workers by retraining and creating new opportunities in the clean energy sector.


Global Implications

The UK's commitment to a coal-free future serves as a powerful example for other nations seeking to decarbonize their energy systems, including peers where Alberta's last coal plant closed recently. The nation's experience demonstrates that a transition to renewable energy sources is both possible and necessary. However, it also highlights the importance of careful planning and addressing the social and economic impacts of such a rapid energy revolution.


The Road Ahead

While the closure of West Burton A Power Station marks a historic milestone, the UK's transition to clean energy is far from complete. Maintaining a reliable and affordable energy supply, even as coal-free power records raise questions about energy bills, will require continued investment in renewable energy sources, energy storage, and advanced grid technologies.

South Australia rides renewables boom to become electricity exporter

Australia electricity grid transition is accelerating as renewables, wind, solar, and storage drive decentralised generation, emissions cuts, and NEM trade shifts, with South Australia becoming a net exporter post-Hazelwood closure and rooftop solar surging.

 

Key Points

Australia electricity shift to renewables, distributed generation and storage, cutting emissions, reshaping NEM flows.

✅ South Australia now exports power post-Hazelwood closure

✅ Rooftop solar is the fastest-growing NEM generation source

✅ Gas peaking and storage investments balance variable renewables

 

The politics may not change much, but Australia’s electricity grid is changing before our very eyes – slowly and inevitably becoming more renewable, more decentralised, and in step with Australia's energy transition that is challenging the pre-conceptions of many in the industry.

The latest national emissions audit from The Australia Institute, which includes an update on key electricity trends in the national electricity market, notes some interesting developments over the last three months.

The most surprising of those developments may be the South Australia achievement, which shows that since the closure of the Hazelwood brown coal generator in Victoria in March 2017, and as renewables outpacing brown coal in other markets, South Australia has become a net exporter of electricity, in net annualised terms.

Hugh Saddler, lead author of the study, notes that this is a big change for South Australia, which in 1999 and 2000, when it had only gas and local coal, used to import 30% of its electricity demand.

#google#

The fact that wholesale prices in South Australia were higher in other states – then, as they are now – has nothing to with wind and solar, but the fact that it has no low-cost conventional source and a peaky demand profile (then and now).

“The difference today is that the state is now taking advantage of its abundant resources of wind and solar radiation, and the new technologies which have made them the lowest cost sources of new generation, to supply much of its electricity requirements,” Saddler writes.

Other things to note about the flows between states is that Victoria was about equal on imports and exports with its three neighbouring states, despite the closure of Hazelwood. NSW continues to import around 10% of its needs from cheaper providers in Queensland.

Gas-fired generation had increased in the last year or two in South Australia as a result of the Northern closure, but is still below the levels of a decade ago.

But because it is expensive, this is likely to spur more investment in storage.

As for rooftop solar, Saddler notes that the share of residential solar in the grid is still relatively small but, despite excess solar risks flagged by distributors, it is the most steadily growing generation source in the NEM.

That line is expected to grow steadily. By 2040, or perhaps 2050, the share of distributed generation, which includes rooftop solar, battery storage and demand management, is expected to reach nearly half of all Australia’s grid demand.

Saddler, says, however, that the increase in large-scale solar over the last few months is a significant milestone in Australia’s transition towards clean electricity generation, mirroring trends in India's on-grid solar development seen in recent years. (See very top graph).

“Firstly, they are a concrete demonstration that the construction cost advantage, which wind enjoyed over solar until a year or two ago, is gone.

“From now on we can expect new capacity to be a mix of both technologies. Indeed, the Clean Energy Regulator states that it expects solar to account for half of all (new renewable) capacity by 2020, and the US is moving toward 30% from wind and solar as well.”
