Renewables became the second-most prevalent U.S. electricity source in 2020

Thermoradiative Diode Power leverages infrared radiation and night-sky cooling to harvest waste heat. Using MCT (mercury cadmium telluride) detectors with photovoltaics, it extends renewable energy generation after sunset, exploiting radiative cooling and low-power density.

Key Points

Technology using MCT infrared diodes to turn radiative Earth-to-space heat loss into electricity, aiding solar at night.

✅ MCT diodes radiate to cold sky, generating tiny current at 20 C

✅ Complements photovoltaics by harvesting post-sunset infrared flux

✅ Potential up to one-tenth solar output with further efficiency gains

Conventional solar technology soaks up rays of incoming sunlight to bump out a voltage. Strange as it seems, some materials are capable of running in reverse, producing power as they radiate heat back into the cold night sky environment.

A team of engineers in Australia has now demonstrated the theory in action, using the kind of technology commonly found in night-vision goggles to generate power, while other research explores electricity from thin air concepts under ambient humidity.

So far, the prototype only generates a small amount of power, and is probably unlikely to become a competitive source of renewable power on its own – but coupled with existing photovoltaics technology and thermal energy into electricity approaches, it could harness the small amount of energy provided by solar cells cooling after a long, hot day's work.

"Photovoltaics, the direct conversion of sunlight into electricity, is an artificial process that humans have developed in order to convert the solar energy into power," says Phoebe Pearce, a physicist from the University of New South Wales.

"In that sense, the thermoradiative process is similar; we are diverting energy flowing in the infrared from a warm Earth into the cold Universe."

By setting atoms in any material jiggling with heat, you're forcing their electrons to generate low-energy ripples of electromagnetic radiation in the form of infrared light, a principle also explored with carbon nanotube energy harvesters in ambient conditions.

As lackluster as this electron-shimmy might be, it still has the potential to kick off a slow current of electricity. All that's needed is a one-way electron traffic signal called a diode.

Made of the right combination of elements, a diode can shuffle electrons down the street as it slowly loses its heat to a cooler environment.

In this case, the diode is made of mercury cadmium telluride (MCT). Already used in devices that detect infrared light, MCT's ability to absorb mid-and long-range infrared light and turn it into a current is well understood.

What hasn't been entirely clear is how this particular trick might be used efficiently as an actual power source.

Warmed to around 20 degrees Celsius (nearly 70 degrees Fahrenheit), one of the tested MCT photovoltaic detectors generated a power density of 2.26 milliwatts per square meter.

Granted, it's not exactly enough to boil a jug of water for your morning coffee. You'd probably need enough MCT panels to cover a few city blocks for that small task.

But that's not really the point, either, given it's still very early days in the field, and there's potential for the technology to develop significantly further in the future.

"Right now, the demonstration we have with the thermoradiative diode is relatively very low power. One of the challenges was actually detecting it," says the study's lead researcher, Ned Ekins-Daukes.

"But the theory says it is possible for this technology to ultimately produce about 1/10th of the power of a solar cell."

At those kinds of efficiencies, it might be worth the effort weaving MCT diodes into more typical photovoltaic networks alongside thin-film waste heat solutions so that they continue to top up batteries long after the Sun sets.

To be clear, the idea of using the planet's cooling as a source of low-energy radiation is one engineers have been entertaining for a while now. Different methods have seen different results, all with their own costs and benefits, with low-cost heat-to-electricity materials also advancing in parallel.

Yet by testing the limits of each and fine-tuning their abilities to soak up more of the infrared bandwidth, we can come up with a suite of technologies and thermoelectric materials capable of wringing every drop of power out of just about any kind of waste heat.

"Down the line, this technology could potentially harvest that energy and remove the need for batteries in certain devices – or help to recharge them," says Ekins-Daukes.

"That isn't something where conventional solar power would necessarily be a viable option."

Canada Net-Zero demands renewable energy deployment, leveraging hydropower to integrate wind, solar, and storage, scaling electrification, cutting oil and gas emissions, aligning policy, carbon pricing, and investment to deliver a clean grid by 2050.

Key Points

A national goal to cut emissions 40-45% by 2030 and reach economy-wide net-zero by 2050 through clean electrification.

✅ Hydropower balances intermittent wind and solar.

✅ Policy, carbon pricing, and investment accelerate deployment.

✅ Clean energy jobs surge as oil and gas decline.

As the UN climate talks draw near, Canada has enormous work left to do to reach its goals of reducing greenhouse gas emissions. Collectively, Canadians have to cut overall greenhouse-gas emissions by 40 to 45 per cent below 2005 levels by 2030 and achieve net-zero by 2050 across the economy.

And whereas countries like the U.K. have dramatically slashed their emissions levels, Canada's one of the few nations where emissions keep skyrocketing, and where fossil fuel extraction keeps increasing every year despite our climate targets.

As Trudeau seeks to cement his political legacy, these are the MPs he’s considering for cabinet
By Andrew Perez | Opinion | October 25th 2021
In the upcoming online Conversations event on Thursday, 11 a.m. PT/2 p.m. ET, host and Canada's National Observer deputy managing editor David McKie will discuss how cleaning up Canada's electricity and renewable energy can put the country on track to hitting its targets with Clean Energy Canada executive director Merran Smith, Canadian Institute for Climate Choices senior economist Dale Beugin, and WaterPower Canada CEO Anne-Raphaëlle Audouin.

Getting to net-zero grid through renewable electricity
“If we wanted to be powered by 100 per cent renewable electricity, including proposals for a fully renewable electricity grid by 2030, Canada is one of the countries where this is actually possible,” said Audouin.

She says for that to happen, it would take a slate of clean energy providers working together to fill the gaps, rather than competing for market dominance.

“You couldn't power Canada just with wind and solar, even with batteries. That being said, renewables happen to work very well together ” she said. “Hydropower already makes up more than 90 per cent of Canada’s renewable generation and 60 per cent of the country’s total electricity needs are currently met thanks to this flexible, dispatchable, abundant source of baseload renewable electricity. It isn’t a stretch of the imagination to envision hydropower and wind and solar working increasingly together to clean up our grid. In fact, hydropower already backs up and allows intermittent renewable energies like wind and solar onto the grid.”

She noted that while hydropower alone won't be the solution, its long history and indisputable suite of attributes — hydroelectricity has been in Canada since the 1890s — will make it a key part of the clean energy transition required to replace coal, natural gas and oil, which still make up around 20 per cent of Canada's power sources.

Canada's vast access to water, wind, biomass, solar, geothermal, and ocean energy, and a federal government that has committed to climate goals, makes us well-positioned to lead the way to a net-zero future and eventually the electrification of our economy. So, what's holding the country back?

The new reality for renewables
According to Clean Energy Canada, it's possible to grow the clean energy sector, but only if businesses invest massively in renewables and governments give guidance and oversight informed by the implications of decarbonizing Canada's electricity grid research.

A recent modelling study from Clean Energy Canada and Navius Research exploring the energy picture here in Canada over the next decade shows our clean energy sector is expected to grow by about 50 per cent by 2030 to around 640,000 people. Already, the clean energy industry provides 430,500 jobs — more than the entire real estate sector — and that growth is expected to accelerate as our dependence on oil and gas decreases. In fact, clean energy jobs in Alberta are predicted to jump 164 per cent over the next decade.

Currently, provinces with the most hydropower generation are also the ones with the lowest electricity rates, reflecting that electricity has been a nationwide climate success in Canada. Wind and solar are now on par, or even more competitive, than natural gas, and that could have big implications for other major sectors of the economy. Grocery giant Loblaws (which owns brands including President's Choice, Joe Fresh, and Asian grocery chain T&T) deployed its fleet of fully electric delivery trucks in recent years, and Hydro-Québec just signed a $20-billion agreement to help power and decarbonize the state of New York over the next 25 years.

In The New Reality, Smith writes that many carbon-intensive industries, such as the mining sector, could also potentially benefit from the increased demand for certain natural resources — like lithium and nickel — as the world switches to electric vehicles and clean power.

“Oil and gas may have dominated Canada’s energy past, but it’s Canada’s clean energy sector that will define its new reality,” Smith emphasized.

Despite its vast potential to be one of the world's clean energy leaders, Canada has a long way to getting on the path to net zero. Even though the country is home to some of the world's leading cleantech companies, such as B.C.-based clean hydrogen fuel cell providers Ballard Power and Loop Energy and Nova Scotia-based carbon utilization company CarbonCure, the country continues to expand fossil fuel extraction to the point that emissions are projected to jump to around 1,500 MtCO2 worth by 2030.

Labrador EV Charging Infrastructure faces gaps, with few fast chargers; Level 2 dominates, fueling range anxiety for Tesla and Chevrolet Bolt drivers, despite rebates and Newfoundland's network linking St. John's to Port aux Basques.

Key Points

It refers to the current and planned network of Level 2 and Level 3 charging sites across Labrador.

✅ 2 public Level 2 chargers: Happy Valley-Goose Bay and Churchill Falls

✅ Phase 2: 3 fast chargers planned for HV-GB, Churchill Falls, Labrador City

✅ $2,500 rebates offered; rural range anxiety still deters buyers

Retired pilot Allan Carlson is used to crossing Labrador by air.

But he recently traversed the Big Land in an entirely new way, driving for hours on end in his electric car.

The vehicle in question is a Tesla Model S P100D, which Carlson says he can drive up to 500 kilometres on a full charge — and sometimes even a little more.

After catching a ferry to Blanc-Sablon, Que., earlier this month, he managed to reach Happy Valley-Goose Bay, over 600 kilometres away.

To get there, though, he had to use the public charging station in Blanc-Sablon. He also had to push the limits of what his car could muster. 

But more affordable mass-market electric vehicles don't have the battery power of a top-of-the-range Tesla, prompting the Big Land's first EV owner to wonder when Labrador infrastructure will catch up to the high-speed charging network recently unveiled across Newfoundland this summer.

Phillip Rideout, an electrician who lives in Nain, bought a Chevrolet Bolt EV for his son — the range of which tops out at under 350 kilometres, depending on driving patterns and weather conditions.

He's comfortable driving the car within Nain but said he's concerned about traveling to southern Labrador on a single charge.

"It's a start in getting these 14 charging stations across the island," Rideout said of Newfoundland's new network, "but there is still more work to be done."

The provincial government continues to push an electric-vehicle future, however, even as energy efficiency rankings trail the national average, despite Labradorians like Rideout feeling left out of the loop.

Bernard Davis, minister of environment and climate change, earlier this month announced that government is accepting applications for its electric-vehicle rebate program, as the N.W.T. EV initiative pursues similar goals.

Under the $500,000 program, anyone looking to buy a new or used EV would be entitled to $2,500 in rebates, an attempt by the provincial government to increase EV adoption.

But according to a survey conducted this year by polling firm Leger for the Canadian Vehicle Manufacturer's Association, 51 per cent of rural Canadians found a lack of fast-charging public infrastructure to be a major deterrent to buying an electric car, even as Atlantic EV interest lags overall, according to recent data.

While Newfoundland's 14-charger network, operated by N.L. Hydro and Newfoundland Power, allows drivers to travel from St. John's to Port aux Basques, and 10 new fast-charging stations are planned along the Trans-Canada in New Brunswick, Labrador in contrast has just two publicly available charging locations: one at the YMCA in Happy Valley-Goose Bay and the other near the town office of Churchill Falls.

This is the proposed second phase of additional Level 2 and Level 3 charging locations across Labrador. (TakeChargeNL)
These are slower, Level 2 chargers, as opposed to newer Level 3 charging stations on the island. A Level 2 system averages 50 kilometres of range per hour, and a Level 3 systems can add up to 250 kilometres within the same time frame, making them about five times faster.

Even though all of the fast-charging stations have gone to Newfoundland, MHA for Lake Melville Perry Trimper is optimistic about Labrador's electric future.

Trimper has owned an EV in St. Johns since 2016, but told CBC he'd be comfortable driving it in Happy Valley-Goose Bay.

He acknowledged, however, that prospective owners in Labrador might not be able to drive far from their home charging outlet. 

More promises
If rural skepticism driven by poor infrastructure continues, the urban population could lead the way in adoption, allowing the new subsidies to disproportionately go toward larger population centres, Davis acknowledged.

"Obviously people are not going to purchase electric vehicles if they don't believe they can charge them where they want to be or where they want to go," Davis said in an interview in early September.

Under the provincial government's Phase 2 proposal, Newfoundland and Labrador is projected to get 19 charging stations, with three going to Labrador in Happy Valley-Goose Bay, Churchill Falls and Labrador City, taking cues from NB Power's public network in building regional coverage.

Davis would not commit to a specific cutoff period for the rebate program or a timeline for the first fast-charging stations in Labrador to be built.

"At some point, we are not going to need to place any subsidy on electric vehicles," he said, "but that time is not today and that's why these subsidies are important right now."

Future demand 
Goose Bay Motors manager Joel Hamlen thinks drivers in Labrador could shift away from gas vehicles eventually, even as EV shortages and wait times persist.

But he says it'll take investment into a charging network to get there.

"If we can get something set up where these people can travel down the roads and use these vehicles in the province … I am sure there will be even more of a demand," Hamlen said.

Canada Net-Zero Electricity 2035 aligns policy and investments with renewables, wind, solar, hydro, storage, and transmission to power electrification of EVs and heat pumps, guided by a stringent clean electricity standard and carbon pricing.

Key Points

A 2035 plan for a zero-emissions grid using renewables, storage and transmission to electrify transport and homes.

✅ Wind, solar, and hydro backed by battery storage and reservoirs

✅ Interprovincial transmission expands reliability and lowers costs

✅ Stringent clean electricity standard and full carbon pricing

Electric vehicles are making inroads in some areas of Canada. But as their numbers grow, will there be enough electrical power for them, and for all the buildings and the industries that are also switching to electricity?

Canada – along with the United States, the European Union and the United Kingdom – is committed to a “net-zero electricity grid by 2035 policy goal”. This target is consistent with the Paris Agreement’s ambition of staying below 1.5 C of global warming, compared with pre-industrial levels.

This target also gives countries their best chance of energy security, as laid out in landmark reports over the past year from the International Energy Agency and the Intergovernmental Panel on Climate Change. A new federal regulation in the form of a clean electricity standard is being developed, but will it be stringent enough to set us up for climate success and avoid dead ends?

Canada starts this work from a relatively low emissions-intensity grid, powered largely by hydroelectricity. However, some provinces such as Alberta, Saskatchewan, Nova Scotia and New Brunswick still have predominantly fossil fuel-powered electricity. Plus, there is a risk of more natural gas generation of electricity in the coming years in most provinces without new federal and provincial regulations.

This means the transition of Canada’s electricity system must solve two problems at once. It must first clean up the existing electricity system, but it must also meet future electricity needs from zero-emissions sources while overall electricity capacity doubles or even triples by 2050.

Canada has enormous potential for renewable generation, even though it remains a solar power laggard in deployment to date. Wind, solar and energy storage are proven, affordable technologies that can be produced here in Canada, while avoiding the volatility of global fossil fuel markets.

As wind and solar have become the cheapest forms of electricity generation in history, we’re already seeing foreign governments and utilities ramp up renewable projects at the pace and scale that would be needed here in Canada, highlighting a significant global electricity market opportunity for Canadian firms at home. In 2020, 280 gigawatts of new capacity was added globally – a 45 per cent increase over the previous year. In Canada, since 2010, annual growth in renewables has so far averaged less than three per cent.

So why aren’t we moving full steam – or electron – ahead? With countries around the world bringing in wind and solar for new generation, why is there so much delay and doubt in Canada, even as analyses explore why the U.S. grid isn’t 100% renewable and remaining barriers?

The modelling team drew on a dataset that accounts for how wind and solar potential varies across the country, through the weeks of the year and the hours of each day. The models provide solutions for the most cost-effective new generation, storage and transmission to add to the grid while ensuring electricity generation meets demand reliably every hour of the year.

The David Suzuki Foundation partnered with the University of Victoria to model the electricity grid of the future.

To better understand future electricity demand, a second modelling team was asked to explore a future when homes and businesses are aggressively electrified; fossil fuel furnaces and boilers are retired and replaced with electric heat pumps; and gasoline and diesel cars are replaced by electric vehicles and public transit. It also dialed up investments in energy efficiency to further reduce the need for energy. These hourly electricity-demand projections were fed back to the models developed at the University of Victoria.

The results? It is possible to meet Canada’s needs for clean electricity reliably and affordably through a focus on expanding wind and solar generation capacity, complemented with new transmission connections between provinces, and other grid improvements.

How is it that such high levels of variable wind and solar can be added to the grid while keeping the lights on 24/7? The model took full advantage of the country’s existing hydroelectric reservoirs, using them as giant batteries, storing water behind the dams when wind and solar generation was high to be used later when renewable generation is low, or when demand is particularly high. The model also invested in more transmission to enable expanded electricity trade between provinces and energy storage in the form of batteries to smooth out the supply of electricity.

Not only is it possible, but the renewable pathway is the safe bet.

There’s no doubt it will take unprecedented effort and scale to transform Canada’s electricity systems. The high electrification pathway would require an 18-fold increase over today’s renewable electricity capacity, deploying an unprecedented amount of new wind, solar and energy storage projects every year from now to 2050. Although the scale seems daunting, countries such as Germany are demonstrating that this pace and scale is possible.

The modelling also showed that small modular nuclear reactors (SMRs) are neither necessary nor cost-effective, making them a poor candidate for continued government subsidies. Likewise, we presented pathways with no need for continued fossil fuel generation with carbon capture and storage (CCS) – an expensive technology with a global track record of burning through public funds while allowing fossil fuel use to expand and while capturing a smaller proportion of the smokestack carbon than promised. We believe that Canada should terminate the significant subsidies and supports it is giving to fossil fuel companies and redirect this support to renewable electricity, energy efficiency and energy affordability programming.

The transition to clean electricity would come with new employment for people living in Canada. Building tomorrow’s grid will support more than 75,000 full-time jobs each year in construction, operation and maintenance of wind, solar and transmission facilities alone.

Regardless of the path chosen, all energy projects in Canada take place on unceded Indigenous territories or treaty land. Decolonizing power structures with benefits to Indigenous communities is imperative. Upholding Indigenous rights and title, ensuring ownership opportunities and decision-making and direct support for Indigenous communities are all essential in how this transition takes place.

Wind, solar, storage and smart grid technologies are evolving rapidly, but our understanding of the possibilities they offer for a zero-emissions future, including debates over clean energy’s dirty secret in some supply chains, appears to be lagging behind reality. As the Institut de L’énergie Trottier observed, decarbonization costs have fallen faster than modellers anticipated.

The shape of tomorrow’s grid will largely depend on policy decisions made today. It’s now up to people living in Canada and their elected representatives to create the right conditions for a renewable revolution that could make the country electric, connected and clean in the years ahead.

To avoid a costly dash-to-gas that will strand assets and to secure early emissions reductions, the electricity sector needs to be fully exposed to the carbon price. The federal government’s announcement that it will move forward with a clean electricity standard – requiring net-zero emissions in the electricity sector by 2035 – will help if the standard is stringent.

Federal funding to encourage provinces to expand interprovincial transmission, including recent grid modernization investments now underway will also move us ahead. At the provincial level, electricity system governance – from utility commission mandates to electricity markets design – needs to be reformed quickly to encourage investments in renewable generation. As fossil fuels are swapped out across the economy, more and more of a household’s total energy bill will come from a local electric utility, so a national energy poverty strategy focused on low-income and equity-seeking households must be a priority.

The payoff from this policy package? Plentiful, reliable, affordable electricity that brings better outcomes for community health and resilience while helping to avoid the worst impacts of climate change.

Nova Scotia’s West Wind Clean Energy Project aims to harness offshore wind power to deliver renewable electricity, expand transmission infrastructure, and position Canada as a global leader in sustainable energy generation.

What is West Wind Clean Energy?

The West Wind Clean Energy Project is Nova Scotia’s $60-billion offshore wind initiative to generate up to 66 GW of clean electricity for Canada’s growing energy needs.

✅ Harnesses offshore wind resources for renewable power generation

✅ Expands grid and transmission infrastructure for clean energy exports

✅ Supports Canada’s transition to a sustainable, low-carbon economy

Nova Scotia has launched one of the most ambitious clean energy projects in Canadian history — a $60-billion plan to build 66 gigawatts (GW) of offshore wind capacity, as countries like the UK expand offshore wind, capable of meeting up to 27 per cent of the nation’s total electricity demand.

Premier Tim Houston unveiled the project, called West Wind, in June, positioning it as a cornerstone of Canada’s broader energy transition and aligning it with Prime Minister Mark Carney’s goal of making the country both a clean energy and conventional energy superpower. Three months later, Carney announced a slate of “nation-building” infrastructure projects the federal government would fast-track. While West Wind was not on the initial list, it was included in a second tier of high-potential proposals still under development.

The plan’s scale is unprecedented for Canada’s offshore energy industry, as organizations like Marine Renewables Canada pivot toward offshore wind to accelerate growth. However, enormous logistical, financial, and market challenges remain. Turbines will not be in the water for years, and the global offshore wind industry itself is facing one of its most difficult periods in over a decade.

“Right now is probably the worst time in 15 years to launch a project like this,” said an executive at a Canadian energy company who requested anonymity. “It’s not Nova Scotia’s fault. It’s just really bad timing.” He pointed to failed offshore wind auctions in Europe, rising costs, and policy reversals in the United States as troubling signals for investors, even as New York’s largest offshore wind project moved ahead this year. “You can’t build the wind and hope the lines come later. You have to build both — together.”

Indeed, transmission infrastructure is emerging as the project’s biggest obstacle. Nova Scotia’s local electricity demand is limited, meaning most of the power would need to be sold to markets in Ontario, Quebec, and New England. Of the $60 billion budgeted for West Wind, $40 billion is allocated to generation, and $20 billion to new transmission — massive sums that require close federal-provincial coordination and long-term investment planning.

Despite the economic headwinds, advocates argue that West Wind could transform Atlantic Canada’s energy landscape and strengthen national energy security, building on recent tidal power investments in Nova Scotia. Peter Nicholson, chair of the Canadian Climate Institute and author of Catching the Wind: How Atlantic Canada Can Become an Energy Superpower, believes the project could redefine Nova Scotia’s role in Canada’s energy transition.

“It’s very well understood where the world is headed,” Nicholson said, noting that wind power is becoming increasingly competitive worldwide. “We’re moving toward an electrical future that’s cleanly generated for economic, environmental, and security reasons. But for that to happen, the economics have to work.” He added that the official “nation-building” designation could give Nova Scotia “a seat at the table” with major utilities in other provinces.

The governments of Canada and Nova Scotia recently issued a notice of strategic direction to the Canada–Nova Scotia Offshore Energy Regulator, aligning with Ottawa’s plan to regulate offshore wind as it begins a prequalification process and designs a call for bids later this year. The initial round will cover just 3 GW of capacity — smaller than the originally envisioned 5 GW — but officials describe it as a first step in a multi-decade plan.

While timing and economics remain uncertain, supporters insist the long-term potential of offshore wind in Nova Scotia is too significant to ignore. As global demand for clean electricity grows and offshore wind moves toward a trillion-dollar global market, they argue, West Wind could help secure Canada’s place as a renewable energy leader — if government and industry can find a way to make the numbers work.

Centrica Dyce Battery Storage will deliver 30MW 2hr capacity in Aberdeenshire, capturing North Sea offshore wind to reduce curtailment, enhance grid flexibility, and strengthen UK energy independence with reliable renewable energy balancing.

Key Points

A 30MW 2hr battery in Dyce, Aberdeenshire, storing North Sea wind to cut curtailment and ease UK grid constraints.

✅ 30MW 2hr system near North Sea offshore wind connection

✅ Cuts curtailment and boosts grid flexibility and reliability

✅ Can power 70,000 homes for an hour with daily cycles

CENTRICA Business Solutions has secured the development rights for a fully consented 30MW 2hr battery storage plant in Aberdeenshire that will help maximise the use of renewable energy in the Scottish North Sea.

The site in Dyce, near Aberdeen is located near a connection for North Sea UK offshore wind farms and will contribute towards managing network constraints – by storing electricity when it is abundant for times when it is not, helping improve the energy independence of the UK and reduce our reliance on fossil fuels. 

Last year, the National Grid paid £244million to wind farm operators to shut down turbines, as they risked overloading the Scottish grid, a process known as curtailment. Battery storage is one method of helping to utilise that wasted energy resource, ensuring fewer green electrons are curtailed. 

Once built, the 30MW 2hr Dyce battery storage plant will store enough energy to power 70,000 homes for an hour. This discharge happens up to four hours per day, as seen in other large-scale deployments like France's largest battery platform that optimise grid balancing.

The project was developed by Cragside Energy Limited, backed by Omni Partners LLP, and obtained planning consent in November 2021. The go-live date for the project is mid-2024, construction should last eight months and will be aligned with the grid connection date.

“Battery storage can play a strategic role in helping to transition away from fossil fuels, by smoothing out the peak demand and troughs associated with renewable energy generation,” said Bill Rees, Director of Centrica Energy Assets. “We should treat renewable energy like a precious resource and projects like this can help to maximise its efficacy.” 

The project forms part of Centrica Energy Assets’ plan to deliver 900MW of solar and battery storage assets by 2026, increasingly paired with solar in global deployments. Centrica already owns and operates the 49MW fast response battery at Roosecote, Cumbria. 

Centrica Business Solutions Managing Director Greg McKenna, said: “Improving the energy independence of the UK is essential to help manage energy costs and move away from fossil fuels. The Government has set a target of a green electricity grid by 2035 – that’s only achievable if we build out the level of flexibility in the system, to help manage supply and demand.”

Centrica Energy Assets will work with Cragside Energy to identify new opportunities in the energy storage space. Cragside Energy’s growing pipeline exceeds 200MW, and focuses on low carbon and flexible assets, including energy storage, solar and peaking plant schemes, supported by falling battery costs across the sector.

Ben Coulston, Director of Cragside Energy, added: “Targeted investment into a complementary mix of diverse energy sources and infrastructure is crucial if the UK is to fully harness its renewable energy potential. Battery storage, such as the project in Dyce, will contribute to the upkeep of a stable and resilient network and we have enjoyed partnering with Centrica as the project transitions into the next phase”.
