Grid Transformer Waste Heat Recovery turns substations into neighborhood boilers, supplying district heating via heat networks, helping National Grid and SSE cut emissions, boost energy efficiency, and advance low carbon, net zero decarbonization.

 

Key Points

Grid Transformer Waste Heat Recovery captures substation heat for district heating, cutting emissions and gas use.

✅ Captures waste heat from National Grid transformers

✅ Feeds SSE district heat networks for nearby homes

✅ Cuts carbon, improves efficiency, aligns with net zero

 

Thousands of homes could soon be warmed by the heat from giant electricity grid transformers for the first time as part of new plans to harness “waste heat” and cut carbon emissions from home heating.

Trials are due to begin on how to capture the heat generated by transmission network transformers, owned by National Grid, to provide home heating for households connected to district heating networks operated by SSE.

Currently, hot air is vented from the giant substations to help cool the transformers that help to control the electricity running through National Grid’s high-voltage transmission lines.

However, if the trial succeeds, about 1,300 National Grid substations could soon act as neighbourhood “boilers”, piping water heated by the substations into nearby heating networks, and on into the thousands of homes that use SSE’s services.

“Electric power transformers generate huge amounts of heat as a byproduct when electricity flows through them. At the moment, this heat is just vented directly into the atmosphere and wasted,” said Nathan Sanders, the managing director of SSE Energy Solutions.

“This groundbreaking project aims to capture that waste heat and effectively turn transformers into community ‘boilers’ that serve local heat networks with a low- or even zero-carbon alternative to fossil-fuel-powered heat sources such as gas boilers, a shift akin to a gas-for-electricity swap in heating markets,” Sanders added.

Alexander Yanushkevich, National Grid’s innovation manager, said the scheme was “essential to achieve net zero” and a “great example of how, taking a whole-system approach, including power-to-gas in Europe precedents, the UK can lead the way in helping accelerate decarbonisation”.

The energy companies believe the scheme could initially reduce heat network carbon emissions by more than 40% compared with fossil gas systems. Once the UK’s electricity system is zero carbon, and with recent milestones where wind was the main source of UK electricity on the grid, the heating solution could play a big role in helping the UK meet its climate targets.

The first trials have begun at National Grid’s specially designed testing site at Deeside in Wales to establish how the waste heat could be used in district heating networks. Once complete, the intellectual property will be shared with smaller regional electricity network owners, which may choose to roll out schemes in their areas.

Tim O’Reilly, the head of strategy at National Grid, said: “We have 1,300 transmission transformers, but there’s no reason why you couldn’t apply this technology to smaller electricity network transformers, too, echoing moves to use more electricity for heat in colder regions.”

Once the trials are complete, National Grid and SSE will have a better idea of how many homes could be warmed using the heat generated by electricity network substations, O’Reilly said, and how the heat can be used in ways that complement virtual power plants for grid resilience.

“The heavier the [electricity] load, which typically reaches a peak at around teatime, the more heat energy the transformer will be able to produce, aligning with times when wind leads the power mix nationally. So it fits quite nicely to when people require heat in the evenings,” he added.

Other projects designed to capture waste heat to use in district heating schemes include trapping the heat generated on the Northern line of London’s tube network to warm homes in Islington, and harnessing the geothermal heat from disused mines for district heating networks in Durham.

Only between 2% and 3% of the UK is connected to a district heating network, but more networks are expected to emerge in the years ahead as the UK tries to reduce the carbon emissions from homes, alongside its nuclear power plans in the wider energy strategy.

Prime minister, B.C. premier announce $1B B.C. battery plant

Maple Ridge Lithium-Ion Battery Plant will be a $1B E-One Moli clean-tech facility in Canada, manufacturing high-performance cells for tools and devices, with federal and provincial funding, creating 450 jobs and boosting battery supply chains.

 

Key Points

A $1B E-One Moli facility in B.C. producing lithium-ion cells, backed by federal and provincial funding.

✅ $204.5M federal and up to $80M B.C. support committed

✅ E-One Moli to create 450 skilled jobs in Maple Ridge

✅ High-performance cells for tools, medical devices, and equipment

 

A lithium-ion battery cell production plant costing more than $1 billion will be built in Maple Ridge, B.C., Prime Minister Justin Trudeau and Premier David Eby jointly announced on Tuesday.

Trudeau and Eby say the new E-One Moli facility will bolster Canada's role as a global leader in clean technology, as recent investments in Quebec's EV battery assembly illustrate today.

It will be the largest factory in Canada to manufacture such high-performance batteries, Trudeau said during the announcement, amid other developments such as a new plant in the Niagara Region supporting EV growth.

The B.C. government will contribute up to $80 million, while the federal government plans to contribute up to $204.5 million to the project. E-One Moli and private sources will supply the rest of the funding. 

Trudeau said B.C. has long been known for its innovation in the clean-technology sector, and securing the clean battery manufacturing project, alongside Northvolt's project near Montreal, will build on that expertise.

"The world is looking to Canada. When we support projects like E-One Moli's new facility in Maple Ridge, we bolster Canada's role as a global clean-tech leader, create good jobs and help keep our air clean," he said.

"This is the future we are building together, every single day. Climate policy is economic policy."

Nelson Chang, chairman of E-One Moli Energy, said the company has always been committed to innovation and creativity as creator of the world's first commercialized lithium-metal battery.

E-One Moli has been operating a plant in Maple Ridge since 1990. Its parent company, Taiwan Cement Corp., is based in Taiwan.

"We believe that human freedom is a chance for us to do good for others and appreciate life's fleeing nature, to leave a positive impact on the world," Chang said.

"We believe that [carbon dioxide] reduction is absolutely the key to success for all future businesses," he said.

The new plant will produce high-performance lithium-cell batteries found in numerous products, including vacuums, medical devices, and power and gardening tools, aligning with B.C.'s grid development and job plans already underway, and is expected to create 450 jobs, making E-One Moli the largest private-sector employer in Maple Ridge.

Eby said every industry needs to find ways to reduce their carbon footprint to ensure they have a prosperous future and every province should do the same, with resource plays like Alberta's lithium supporting the EV supply chain today.

It's the responsible thing to do given the record wildfires, extreme heat, and atmospheric rivers that caused catastrophic flooding in B.C., he said, with large-scale battery storage in southwestern Ontario helping grid reliability.

"We know that this is what we have to do. The people who suggest that we have to accept that as the future and stop taking action are simply wrong."

Trudeau, Eby and Chang toured the existing plant in Maple Ridge, east of Vancouver, before making the announcement.

The prime minister wove his way around several machines and apologized to technicians about the commotion his visit was creating.

The Canadian Taxpayers Federation criticized the federal and B.C. governments for the announcement, saying in a statement the multimillion-dollar handout to the battery firm will cost taxpayers hundreds of thousands of dollars for each job.

Federation director Franco Terrazzano said the Trudeau government has recently given "buckets of cash" to corporations such as Volkswagen, Stellantis, the Ford Motor Company and Northvolt.

"Instead of raising taxes on ordinary Canadians and handing out corporate welfare, governments should be cutting red tape and taxes to grow the economy," said Terrazzano. 

Construction is expected to start next June, as EV assembly deals put Canada in the race, and the company plans for the facility to be fully operational in 2028.

Alberta set to retire coal power by 2023, ahead of 2030 provincial deadline

Alberta coal phaseout accelerates as utilities convert to natural gas, cutting emissions under TIER regulations and deploying hydrogen-ready, carbon capture capable plants, alongside new solar projects in a competitive, deregulated electricity market.

 

Key Points

A provincewide shift from coal to natural gas and renewables, cutting power emissions years ahead of the 2030 target.

✅ Capital Power, TransAlta converting coal units to gas

✅ TIER pricing drives efficiency, carbon capture readiness

✅ Hydrogen-ready turbines, solar projects boost renewables

 

Alberta is set to meet its goal to eliminate coal-fired electricity production years earlier than its 2030 target, amid a broader shift to cleaner energy in the province, thanks to recently announced utility conversion projects.

Capital Power Corp.’s plan to spend nearly $1 billion to switch two coal-fired power units west of Edmonton to natural gas, and stop using coal entirely by 2023, was welcomed by both the province and the Pembina Institute environmental think-tank.

In 2014, 55 per cent of Alberta’s electricity was produced from 18 coal-fired generators. The Alberta government announced in 2015 it would eliminate emissions from coal-fired electricity generation by 2030.

Dale Nally, associate minister of Natural Gas and Electricity, said Friday that decisions by Capital Power and other utilities to abandon coal will be good for the environment and demonstrates investor confidence in Alberta’s deregulated electricity market, where the power price cap has come under scrutiny.

He credited the government’s Technology Innovation and Emissions Reduction (TIER) regulations, which put a price on industrial greenhouse gas emissions, as a key factor in motivating the conversions.

“Capital Power’s transition to gas is a great example of how private industry is responding effectively to TIER, as it transitions these facilities to become carbon capture and hydrogen ready, which will drive future emissions reductions,” Nally said in an email.

Capital Power said direct carbon dioxide emissions at its Genesee power facility near Edmonton will be about 3.4 million tonnes per year lower than 2019 emission levels when the project is complete.

It says the natural gas combined cycle units it’s installing will be the most efficient in Canada, adding they will be capable of running on 30 per cent hydrogen initially, with the option to run on 95 per cent hydrogen in future with minor investments.

In November, Calgary-based TransAlta Corp. said it will end operations at its Highvale thermal coal mine west of Edmonton by the end of 2021 as it switches to natural gas at all of its operated coal-fired plants in Canada four years earlier than previously planned.

The Highvale surface coal mine is the largest in Canada, and has been in operation on the south shore of Wabamun Lake in Parkland County since 1970.

The moves by the two utilities and rival Atco Ltd., which announced three years ago it would convert to gas at all of its plants by this year, mean significant emissions reduction and better health for Albertans, said Binnu Jeyakumar, director of clean energy for Pembina.

“Alberta’s early coal phaseout is also a great lesson in good policy-making done in collaboration with industry and civil society,” she said.

“As we continue with this transformation of our electricity sector, it is paramount that efforts to support impacted workers and communities are undertaken.”

She added the growing cost-competitiveness of renewable energy, such as wind power, makes coal plant retirements possible, applauding Capital Power’s plans to increase its investments in solar power.

In Ontario, clean power policy remains a focus as the province evaluates its energy mix.

The company announced it would go ahead with its 75-megawatt Enchant Solar power project in southern Alberta, investing between $90 million and $100 million, and that it has signed a 25-year power purchase agreement with a Canadian company for its 40.5-MW Strathmore Solar project now under construction east of Calgary.

P.E.I. government exploring ways for communities to generate their own electricity

P.E.I. Community Energy Independence empowers local microgrids through renewable generation, battery storage, and legislative reform, enabling community-owned power, stable electricity rates, and grid-friendly distributed generation across Island communities with wind, biomass, and net metering models.

 

Key Points

A program enabling communities to generate and store renewable power under supportive laws and grid-friendly models.

✅ Legislative review of Electric Power and Renewable Energy Acts

✅ Community microgrids with wind, biomass, and battery storage

✅ Grid integration without raising rates via Maritime Electric

 

The P.E.I. government is taking steps to review energy legislation and explore new options when it comes to generating power across Island communities.

Energy Minister Steven Myers said one of those options will be identifying ways for Island communities to generate their own energy, aligning with a federal electrification study now examining how electricity can reduce or eliminate fossil fuels. 

He said the move would provide energy independence, create jobs and economic development, and save the communities on their energy bills, as seen with an electricity bill credit in Newfoundland that eased costs for consumers.

But the move will require sweeping legislative changes, that may include the merging of the Electric Power Act and the Renewable Energy Act, similar to an electricity market overhaul in Connecticut seen in other jurisdictions.  

Myers said creating energy independence should ensure a steady supply of electricity while also ensuring costs remain reasonable for P.E.I. residents, even as a Nova Scotia electricity rate hike highlights regional cost pressures.   

"We have communities that are looking to generate their own electricity for their own needs," said Myers, adding the province will not dictate what energy sources communities can invest in. 

He also said the province wants to find new community-based models that will complement existing services.

"How do we do that in a way that we don't impact the grid, that we don't impact the service that Maritime Electric is delivering, mindful of a seasonal rate backlash in New Brunswick that illustrates consumer concerns, that we don't drive up the rates for all other Islanders."

Last fall, a group of P.E.I. MLAs traveled to Samsø, a small Danish island, where they learned about renewable and sustainable energy systems being used there.

Samsø produces 100 per cent of its electricity from wind and biomass, and utilities like HECO meeting renewable goals early show how quickly transitions can occur. The P.E.I. government said the Island produces 25 per cent of its electricity from wind. 

Following the trip, Myers said he was impressed by the control the island had over its energy production and would like to see if a similar model could work on P.E.I. 

Myers said the legislative review will also look at different ways to store energy on the Island. 

He said that will allow communities to sell that excess energy into the provincial electricity grid, and those revenues could be redirected into that community's priorities. 

'For the survival and the future of their community'
"This is kind of a model that we had suggested that would be in place that would allow people in their own community to produce a revenue stream for themselves that they could then turn into projects like rinks, or parks, or tennis courts or whatever it is that community thinks is the most important thing for the survival and the future of their community," said Myers.

The province said Maritime Electric, Summerside Electric and the P.E.I. Energy Corporation will be involved in the review, recognizing that a Nova Scotia ruling on rate-setting powers underscores regulatory limits 

Government also wants to hear from Islanders and will be accepting written submissions beginning Monday. Myers said the province is also planning to host public consultations, but because of COVID-19, those will be held virtually in mid-June.

Myers calls this a major move, one that will take time. He said he doesn't expect the legislation to be made public until the spring of 2021.

"I want to make sure we take our time and do the proper consultation."

London Gateway Unveils World’s First All-Electric Berth

London Gateway All-Electric Berth enables shore power and cold ironing for container ships, cutting emissions, improving efficiency, and supporting green logistics, IMO targets, and UK net-zero goals through grid connection and port electrification.

 

Key Points

It is a shore power berth supplying electricity to ships, cutting emissions and costs while boosting port efficiency.

✅ Grid connection enables cold ironing for container ships

✅ Supports IMO decarbonization and UK net-zero goals

✅ Stabilizes energy costs versus marine fuels

 

London Gateway, one of the UK’s premier deep-water ports, has unveiled the world’s first all-electric berth, marking a significant milestone in sustainable port operations. This innovative development aims to enhance the port's capacity while reducing its environmental impact. The all-electric berth, which powers vessels using electricity, similar to emerging offshore vessel charging solutions, instead of traditional fuel sources, is expected to greatly improve operational efficiency and cut emissions from ships docking at the port.

The launch of this electric berth is part of London Gateway’s broader strategy to become a leader in green logistics, with parallels in electric truck deployments at California ports that support port decarbonization, aligning with the UK’s ambitious climate goals. By transitioning to electric power, the port reduces reliance on fossil fuels and significantly lowers carbon emissions, contributing to a cleaner environment and supporting the maritime industry’s transition towards sustainability.

The berth will provide cleaner power to container ships, enabling them to connect to the grid while docked, similar to electric ships on the B.C. coast, rather than running their engines, which traditionally contribute to pollution. This innovation supports the UK's broader push for decarbonizing its transportation and logistics sector, especially as the global shipping industry faces increasing pressure to reduce its carbon footprint.

The new infrastructure is expected to increase London Gateway’s operational capacity, allowing for a higher volume of traffic while simultaneously addressing the environmental challenges posed by growing port activities. By integrating advanced technologies like the all-electric berth, and advances such as battery-electric high-speed ferries, the port can handle more shipments without expanding its reliance on traditional fuel-based power sources. This could lead to increased cargo throughput, as shipping lines are incentivized to use a greener, more efficient port for their operations.

The project aligns with broader global trends, including electric flying ferries in Berlin, as ports and shipping companies seek to meet international standards set by the International Maritime Organization (IMO) and other regulatory bodies. The IMO has set aggressive targets for reducing greenhouse gas emissions from shipping, and the UK has pledged to be net-zero by 2050, with the shipping sector playing a crucial role in that transition.

In addition to its environmental benefits, the electric berth also helps reduce the operational costs for shipping lines, as seen with electric ferries scaling in B.C. programs across the sector. Traditional fuel costs can be volatile, whereas electric power offers a more stable and predictable expense. This cost stability could make London Gateway an even more attractive port for international shipping companies, further boosting its competitive position in the global market.

Furthermore, the project is expected to have broader economic benefits, generating jobs and fostering innovation, such as hydrogen crane projects in Vancouver, within the green technology and maritime sectors. London Gateway has already made significant strides in sustainable practices, including a focus on automated systems and energy-efficient logistics solutions. The introduction of the all-electric berth is the latest in a series of initiatives aimed at strengthening the port’s sustainability credentials.

This groundbreaking development sets a precedent for other global ports to adopt similar sustainable technologies. As more ports embrace electrification and other green solutions, the shipping industry could experience a dramatic reduction in its environmental footprint. This shift could have a cascading effect on the wider logistics and supply chain industries, leading to cleaner and more efficient global trade.

London Gateway’s all-electric berth represents a forward-thinking approach to the challenges of climate change and the need for sustainability in the maritime sector. With its ability to reduce emissions, improve port capacity, and enhance operational efficiency, this pioneering project is poised to reshape the future of global shipping. As more ports around the world follow suit, the potential for widespread environmental impact in the shipping industry is significant, providing hope for a greener future in international trade.

Balancing Act: Germany's Power Sector Navigates Energy Transition

Germany January Power Mix shows gas-fired generation rising, coal steady, and nuclear phaseout impacts, amid cold weather, energy prices, industrial demand, and emissions targets shaping renewables, grid stability, and security of supply.

 

Key Points

The January electricity mix, highlighting gas, coal, renewables, and nuclear exit effects on emissions, prices, and demand.

✅ Gas output up 13% to 8.74 TWh, share at 18.6%.

✅ Coal share 23%, down year on year, steady vs late 2023.

✅ Nuclear gap filled by gas and coal; emissions below Jan 2023.

 

Germany's electricity generation in January presented a fascinating snapshot of its energy transition journey. As the country strives to move away from fossil fuels, with renewables overtaking coal and nuclear in its power mix, it grapples with the realities of replacing nuclear power and meeting fluctuating energy demands.

Gas Takes the Lead:

Gas-fired power plants saw their highest output in two years, generating 8.74 terawatt hours (TWh). This 13% increase compared to January 2023 compensated for the closure of nuclear reactors, which were extended during the energy crisis to shore up supply, and colder weather driving up heating needs. This reliance on gas, however, pushed its share in the electricity mix to 18.6%, highlighting Germany's continued dependence on fossil fuels.

Coal Fades, but Not Forgotten:

While gas surged, coal-fired generation remained below previous levels, dropping 29% from January 2023. However, it stayed relatively flat compared to late 2023, suggesting utilities haven't entirely eliminated it. Coal still held a 23% share, and periodic coal reliance remains evident, exceeding gas' contribution, reflecting its role as a reliable backup for intermittent renewable sources like wind.

Nuclear Void and its Fallout:

The shutdown of nuclear plants in April 2023 created a significant gap, previously accounting for an average of 12% of annual electricity output. This loss is being compensated through gas and coal, with gas currently the preferred choice, even as a nuclear option debate persists among policymakers. This strategy kept January's power sector emissions lower than the previous year, but rising demand could shift the balance.

Industry's Uncertain Impact:

Germany's industrial sector, a major energy consumer, is facing challenges like high energy prices and weak consumer demand. While the government aims to foster industrial recovery, uncertainties linger due to a shaky coalition and limited budget, and debate about a possible nuclear resurgence continues in parallel, which could reshape policy. Any future industrial revival would likely increase energy demand and potentially necessitate more gas or coal.

Cost-Driven Choices and Emission Concerns:

The choice between gas and coal depends on their relative costs, in a system pursuing a coal and nuclear phase-out under long-term policy. Currently, gas seems more favorable emission-wise, but if its price rises, coal might become more attractive, impacting overall emissions.

Looking Ahead:

Germany's energy transition faces a complex balancing act, with persistent grid expansion woes and exposure to cheap gas complicating progress. While the reliance on gas and coal highlights the difficulties in replacing nuclear, the focus on emissions reduction is encouraging. Navigating the challenges of affordability, industrial needs, and climate goals will be crucial for a successful transition to a clean and secure energy future.
