A federal advisory panel announced that a nuclear reactor slated for use across the Southeast is reasonably safe, a step forward for utility firms hoping to build a new wave of nuclear power plants.
The nonbinding findings from the Advisory Committee on Reactor Safeguards came after its assessment of the Westinghouse Electric Co.'s AP1000 reactor, which utility companies have selected to power as many as seven proposed nuclear plants in Alabama, Florida, Georgia, North Carolina and South Carolina.
Officials at the Nuclear Regulatory Commission will consider the advisory panel's report before deciding whether to approve the latest design of the AP1000, a decision expected sometime next year.
"We conclude that there is reasonable assurance that the revised design can be built and operated without undue risk to the health and safety of the public," Said Abdel-Khalik, chairman of the advisory group, said in a letter.
Abdel-Khalik said the findings were contingent on other reviews evaluating whether the reactor can safely withstand the crash of a large jetliner and separate long-term cooling issues.
If approved, Westinghouse Electric's reactor could produce electricity at a new fleet of nuclear plants. Utility firms argue nuclear plants provide power without burning fossil fuels, although detractors question whether the plants can be built economically and safely.
The industry ground to a near-halt in the 1970s because of a dismal economy, reduced electricity needs and opposition following an infamous accident at the Three Mile Island nuclear plant in Pennsylvania. Federal officials have not issued a permit to break ground on a new plant since 1978.
Major utilities want to reverse the trend.
The Atlanta-based Southern Co. and its partners are seeking to build two AP1000 reactors at Plant Vogtle near Waynesboro. President Barack Obama's administration has offered the company roughly $8 billion in federal loan guarantees to help finance the $14 billion project.
Southern Co. officials expect the NRC will rule on the AP1000 design next year, setting the stage for a final decision on the Plant Vogtle expansion in the fall or winter. Power plant permits cannot be issued until the reactors powering them are certified as safe.
"To us, it's a positive sign," said Carrie Phillips, a Southern Co. spokeswoman. "It clears the path so the process going forward isn't going to be impacted by the design certification."
Federal regulators approved an earlier version of the AP1000, but it was never constructed in the United States. Rival designs such as GE Hitachi Nuclear Energy's ABWR and the ESBWR, Areva's EPR and the US-APWR from Mitsubishi Heavy Industries are also being considered for use.
Besides Georgia, Westinghouse has contracts to build its reactors in Levy County, Fla., and Fairfield County, S.C. Utility firms in Alabama and North Carolina earlier submitted applications to the NRC seeking to use the same technology. Four AP1000 reactors are under construction in China.
Canadian Softwood Lumber Tariffs challenge British Columbia's forestry sector, strain U.S.-Canada trade, and risk redirecting critical minerals and energy resources, threatening North American supply chains, manufacturing, and energy security across integrated markets.
Key Points
Duties imposed by the U.S. on Canadian lumber, affecting BC forestry, trade flows, and North American energy security.
✅ U.S. duties strain BC forestry and cross-border supply chains
✅ Risks redirecting critical minerals and energy exports
✅ Tariff rollback could bolster North American energy security
British Columbia Premier David Eby has raised concerns that U.S. tariffs on Canadian softwood lumber are prompting the province to redirect its critical minerals and energy resources, while B.C. challenges Alberta's electricity export restrictions domestically, away from the United States. In a recent interview, Eby emphasized the broader implications of these tariffs, suggesting they could undermine North American energy security and put electricity exports at risk across the border.
Since 2017, the U.S. Department of Commerce has imposed tariffs on Canadian softwood lumber imports, alleging that Canadian producers benefit from unfair subsidies. These duties have been a persistent source of tension between the two nations, coinciding with Canadian support for energy and mineral tariffs and significantly impacting British Columbia's forestry sector—a cornerstone of the province's economy.
Premier Eby highlighted that the financial strain imposed by these tariffs not only jeopardizes the Canadian forestry industry but also has unintended repercussions for the United States. He pointed out that the economic challenges faced by Canadian producers might lead them to seek alternative markets for their critical minerals and energy resources, as tariff threats boost support for Canadian energy projects domestically, thereby reducing the supply to the U.S. British Columbia is endowed with an abundance of critical minerals essential for various industries, including technology and defense.
The potential redirection of these resources could have significant consequences for American industries that depend on a stable and affordable supply of critical minerals and energy. Eby suggested that the tariffs might incentivize Canadian producers to explore other international markets, even as experts advise against cutting Quebec's energy exports amid the tariff dispute, diminishing the availability of these vital resources to the U.S.
In light of these concerns, Premier Eby has advocated for a reassessment of the tariffs, urging a more cooperative approach between Canada and the United States. He contends that eliminating the tariffs would be mutually beneficial, aligning with views that Biden is better for Canada's energy sector and cross-border collaboration, ensuring a consistent supply of critical resources and fostering economic growth in both countries.
The issue of U.S. tariffs on Canadian softwood lumber remains complex and contentious, with far-reaching implications for trade relations and resource distribution between the two nations. As discussions continue, stakeholders on both sides of the border are closely monitoring the situation, noting that Ford has threatened to cut U.S. electricity exports amid trade tensions, recognizing the importance of collaboration in addressing shared economic and security challenges.
Electric power market crisis highlights grid reliability risks as coal and nuclear retire amid subsidies, mandates, and cheap natural gas; intermittent wind and solar raise blackout concerns, resilience costs, and pricing distortions across regulated markets.
Key Points
Reliability and cost risks as coal and nuclear retire; subsidies distort prices; intermittent renewables strain grid.
✅ Coal and nuclear retirements reduce baseload capacity
✅ Subsidies and mandates distort market pricing signals
✅ Intermittent renewables increase blackout and grid risk
Is anyone paying any attention to the crisis that is going on in our electric power markets?
Over the past six months at least four major nuclear power plants have been slated for shutdown, including the last one in operation in California. Meanwhile, dozens of coal plants have been shuttered as well — despite low prices and cleaner coal. Some of our major coal companies may go into bankruptcy.
This is a dangerous game we are playing here with our most valuable resource — outside of clean air and water. Traditionally, we've received almost half our electric power nationwide from coal and nuclear power, and for good reason. They are cheap sources of power and they are highly resilient and reliable.
The disruption to coal and nuclear power wouldn't be disturbing if this were happening as a result of market forces. That's only partially the case.
#google#
The amazing shale oil and gas revolution is providing Americans with cheap gas for home heating and power generation. Hooray. The price of natural gas has fallen by nearly two-thirds over the last decade and this has put enormous price pressure on other forms of power generation.
But this is not a free-market story of Schumpeterian creative destruction. If it were, then wind and solar power would have been shutdown years ago. They can't possibly compete on a level playing field with $3 natural gas.
In most markets solar and wind power survive purely because the states mandate that as much as 30 percent of residential and commercial power come from these sources. The utilities have to buy it regardless of price, even as electricity demand is flat in many regions. What a sweet deal. The California state legislature just mandated that every new home spend $10,000 on solar panels on the roof.
Well over $100 billion of subsidies to big wind and big solar were doled out over the last decade, and even with the avalanche of taxpayer subsidies and bailout funds many of these companies like Solyndra (which received $500 million in handouts) failed, underscoring why a green revolution hasn't materialized as promised.
These industries are not anywhere close to self sufficiency. In 2017 amid utility trends to watch the wind industry admitted that without a continuation of a multi-billion tax credit, the wind turbines would stop turning.
This combines with the left's war on coal through regulations that have destroyed coal plants in many areas. (Thank goodness for the exports of coal or the industry would be in much bigger trouble.)
Bottom line: Our power market is a Soviet central planner's dream come true and it is extinguishing our coal and nuclear industries.
Why should anyone care?
First, because government subsidies, regulations and mandates make electric power more expensive. Natural gas prices have fallen by two-thirds, but electric power costs have still risen in most areas — thanks to the renewable mandates.
More importantly, the electric power market isn't accurately pricing in the value of resilience and reliability. What is the value of making sure the lights don't go off? What is the cost to the economy and human health if we have rolling brownouts and blackouts because the aging U.S. grid doesn't have enough juice during peak demand.
Politicians, utilities and federal regulators are shortsightedly killing our coal and nuclear capacities without considering the risk of future energy shortages and power disruptions. Once a nuclear plant is shutdown, you can't just fire it back up again when you need it.
Wind and solar are notoriously unreliable. Most places where wind power is used, coal plants are needed to back up the system during peak energy use and when the wind isn't blowing.
The first choice to fix energy markets is to finally end the tangled web of layers and layers of taxpayer subsidies and mandates and let the market choose. Alas, that's nearly impossible given the political clout of big wind and solar.
The second best solution is for the regulators and utilities to take into account the grid reliability and safety of our energy. Would people be willing to pay a little more for their power to ensure against brownouts? I sure would. The cost of having too little energy far exceeds the cost of having too much.
A glass of water costs pennies, but if you're in a desert dying of thirst, that water may be worth thousands of dollars.
I'll admit I'm not sure what the best solution is to the power plant closures. But if we have major towns and cities in the country without electric power for stretches of time because of green energy fixation, Americans are going to be mighty angry and our economy will take a major hit.
When our manufacturers, schools, hospitals, the internet and iPhones shut down, we're not going to think wind and solar power are so chic.
If the lights start to go out five or 10 years from now, we will look back at what is happening today and wonder how we could have been so darn stupid.
AI Energy Consumption strains corporate electricity bills as data centers and HPC workloads run nonstop, driving carbon emissions. Efficiency upgrades, renewable energy, and algorithm optimization help control costs and enhance sustainability across industries.
Key Points
AI Energy Consumption is the power used by AI compute and data centers, impacting costs and sustainability.
✅ Optimize cooling, hardware, and workloads to cut kWh per inference
✅ Integrate on-site solar, wind, or PPAs to offset data center power
✅ Tune models and algorithms to reduce compute and latency
Artificial Intelligence (AI) is revolutionizing industries with its promise of increased efficiency and productivity. However, as businesses integrate AI technologies into their operations, there's a significant and often overlooked impact: the strain on corporate electricity bills.
AI's Growing Energy Demand
The adoption of AI entails the deployment of high-performance computing systems, data centers, and sophisticated algorithms that require substantial energy consumption. These systems operate around the clock, processing massive amounts of data and performing complex computations, and, much like the impact on utilities seen with major EV rollouts, contributing to a notable increase in electricity usage for businesses.
Industries Affected
Various sectors, including finance, healthcare, manufacturing, and technology, rely on AI-driven applications for tasks ranging from data analysis and predictive modeling to customer service automation and supply chain optimization, while manufacturing is influenced by ongoing electric motor market growth that increases electrified processes.
Cost Implications
The rise in electricity consumption due to AI deployments translates into higher operational costs for businesses. Corporate entities must budget accordingly for increased electricity bills, which can impact profit margins and financial planning, especially in regions experiencing electricity price volatility in Europe amid market reforms. Managing these costs effectively becomes crucial to maintaining competitiveness and sustainability in the marketplace.
Sustainability Challenges
The environmental impact of heightened electricity consumption cannot be overlooked. Increased energy demand from AI technologies contributes to carbon emissions and environmental footprints, alongside rising e-mobility demand forecasts that pressure grids, posing challenges for businesses striving to meet sustainability goals and regulatory requirements.
Mitigation Strategies
To address the escalating electricity bills associated with AI, businesses are exploring various mitigation strategies:
Energy Efficiency Measures: Implementing energy-efficient practices, such as optimizing data center cooling systems, upgrading to energy-efficient hardware, and adopting smart energy management solutions, can help reduce electricity consumption.
Renewable Energy Integration: Investing in renewable energy sources like solar or wind power and energy storage solutions to enhance flexibility can offset electricity costs and align with corporate sustainability initiatives.
Algorithm Optimization: Fine-tuning AI algorithms to improve computational efficiency and reduce processing times can lower energy demands without compromising performance.
Cost-Benefit Analysis: Conducting thorough cost-benefit analyses of AI deployments to assess energy consumption against operational benefits and potential rate impacts, informed by cases where EV adoption can benefit customers in broader electricity markets, helps businesses make informed decisions and prioritize energy-saving initiatives.
Future Outlook
As AI continues to evolve and permeate more aspects of business operations, the demand for electricity will likely intensify and may coincide with broader EV demand projections that increase grid loads. Balancing the benefits of AI-driven innovation with the challenges of increased energy consumption requires proactive energy management strategies and investments in sustainable technologies.
Conclusion
The integration of AI technologies presents significant opportunities for businesses to enhance productivity and competitiveness. However, the corresponding surge in electricity bills underscores the importance of proactive energy management and sustainability practices. By adopting energy-efficient measures, leveraging renewable energy sources, and optimizing AI deployments, businesses can mitigate cost impacts, reduce environmental footprints, and foster long-term operational resilience in an increasingly AI-driven economy.
Boeing 787 More-Electric Architecture replaces pneumatics with bleedless pressurization, VFSG starter-generators, electric brakes, and heated wing anti-ice, leveraging APU, RAT, batteries, and airport ground power for efficient, redundant electrical power distribution.
Key Points
An integrated, bleedless electrical system powering start, pressurization, brakes, and anti-ice via VFSGs, APU and RAT.
✅ VFSGs start engines, then generate 235Vac variable-frequency power
✅ Bleedless pressurization, electric anti-ice improve fuel efficiency
✅ Electric brakes cut hydraulic weight and simplify maintenance
The 787 Dreamliner is different to most commercial aircraft flying the skies today. On the surface it may seem pretty similar to the likes of the 777 and A350, but get under the skin and it’s a whole different aircraft.
When Boeing designed the 787, in order to make it as fuel efficient as possible, it had to completely shake up the way some of the normal aircraft systems operated. Traditionally, systems such as the pressurization, engine start and wing anti-ice were powered by pneumatics. The wheel brakes were powered by the hydraulics. These essential systems required a lot of physical architecture and with that comes weight and maintenance. This got engineers thinking.
What if the brakes didn’t need the hydraulics? What if the engines could be started without the pneumatic system? What if the pressurisation system didn’t need bleed air from the engines? Imagine if all these systems could be powered electrically… so that’s what they did.
Power sources
The 787 uses a lot of electricity. Therefore, to keep up with the demand, it has a number of sources of power, much as grid operators track supply on the GB energy dashboard to balance loads. Depending on whether the aircraft is on the ground with its engines off or in the air with both engines running, different combinations of the power sources are used.
Engine starter/generators
The main source of power comes from four 235Vac variable frequency engine starter/generators (VFSGs). There are two of these in each engine. These function as electrically powered starter motors for the engine start, and once the engine is running, then act as engine driven generators.
The generators in the left engine are designated as L1 and L2, the two in the right engine are R1 and R2. They are connected to their respective engine gearbox to generate electrical power directly proportional to the engine speed. With the engines running, the generators provide electrical power to all the aircraft systems.
APU starter/generators
In the tail of most commercial aircraft sits a small engine, the Auxiliary Power Unit (APU). While this does not provide any power for aircraft propulsion, it does provide electrics for when the engines are not running.
The APU of the 787 has the same generators as each of the engines — two 235Vac VFSGs, designated L and R. They act as starter motors to get the APU going and once running, then act as generators. The power generated is once again directly proportional to the APU speed.
The APU not only provides power to the aircraft on the ground when the engines are switched off, but it can also provide power in flight should there be a problem with one of the engine generators.
Battery power
The aircraft has one main battery and one APU battery. The latter is quite basic, providing power to start the APU and for some of the external aircraft lighting.
The main battery is there to power the aircraft up when everything has been switched off and also in cases of extreme electrical failure in flight, and in the grid context, alternatives such as gravity power storage are being explored for long-duration resilience. It provides power to start the APU, acts as a back-up for the brakes and also feeds the captain’s flight instruments until the Ram Air Turbine deploys.
Ram air turbine (RAT) generator
When you need this, you’re really not having a great day. The RAT is a small propeller which automatically drops out of the underside of the aircraft in the event of a double engine failure (or when all three hydraulics system pressures are low). It can also be deployed manually by pressing a switch in the flight deck.
Once deployed into the airflow, the RAT spins up and turns the RAT generator. This provides enough electrical power to operate the captain’s flight instruments and other essentials items for communication, navigation and flight controls.
External power
Using the APU on the ground for electrics is fine, but they do tend to be quite noisy. Not great for airports wishing to keep their noise footprint down. To enable aircraft to be powered without the APU, most big airports will have a ground power system drawing from national grids, including output from facilities such as Barakah Unit 1 as part of the mix. Large cables from the airport power supply connect 115Vac to the aircraft and allow pilots to shut down the APU. This not only keeps the noise down but also saves on the fuel which the APU would use.
The 787 has three external power inputs — two at the front and one at the rear. The forward system is used to power systems required for ground operations such as lighting, cargo door operation and some cabin systems. If only one forward power source is connected, only very limited functions will be available.
The aft external power is only used when the ground power is required for engine start.
Circuit breakers
Most flight decks you visit will have the back wall covered in circuit breakers — CBs. If there is a problem with a system, the circuit breaker may “pop” to preserve the aircraft electrical system. If a particular system is not working, part of the engineers procedure may require them to pull and “collar” a CB — placing a small ring around the CB to stop it from being pushed back in. However, on the 787 there are no physical circuit breakers. You’ve guessed it, they’re electric.
Within the Multi Function Display screen is the Circuit Breaker Indication and Control (CBIC). From here, engineers and pilots are able to access all the “CBs” which would normally be on the back wall of the flight deck. If an operational procedure requires it, engineers are able to electrically pull and collar a CB giving the same result as a conventional CB.
Not only does this mean that the there are no physical CBs which may need replacing, it also creates space behind the flight deck which can be utilised for the galley area and cabin.
A normal flight
While it’s useful to have all these systems, they are never all used at the same time, and, as the power sector’s COVID-19 mitigation strategies showed, resilience planning matters across operations. Depending on the stage of the flight, different power sources will be used, sometimes in conjunction with others, to supply the required power.
On the ground
When we arrive at the aircraft, more often than not the aircraft is plugged into the external power with the APU off. Electricity is the blood of the 787 and it doesn’t like to be without a good supply constantly pumping through its system, and, as seen in NYC electric rhythms during COVID-19, demand patterns can shift quickly. Ground staff will connect two forward external power sources, as this enables us to operate the maximum number of systems as we prepare the aircraft for departure.
Whilst connected to the external source, there is not enough power to run the air conditioning system. As a result, whilst the APU is off, air conditioning is provided by Preconditioned Air (PCA) units on the ground. These connect to the aircraft by a pipe and pump cool air into the cabin to keep the temperature at a comfortable level.
APU start
As we near departure time, we need to start making some changes to the configuration of the electrical system. Before we can push back , the external power needs to be disconnected — the airports don’t take too kindly to us taking their cables with us — and since that supply ultimately comes from the grid, projects like the Bruce Power upgrade increase available capacity during peaks, but we need to generate our own power before we start the engines so to do this, we use the APU.
The APU, like any engine, takes a little time to start up, around 90 seconds or so. If you remember from before, the external power only supplies 115Vac whereas the two VFSGs in the APU each provide 235Vac. As a result, as soon as the APU is running, it automatically takes over the running of the electrical systems. The ground staff are then clear to disconnect the ground power.
If you read my article on how the 787 is pressurised, you’ll know that it’s powered by the electrical system. As soon as the APU is supplying the electricity, there is enough power to run the aircraft air conditioning. The PCA can then be removed.
Engine start
Once all doors and hatches are closed, external cables and pipes have been removed and the APU is running, we’re ready to push back from the gate and start our engines. Both engines are normally started at the same time, unless the outside air temperature is below 5°C.
On other aircraft types, the engines require high pressure air from the APU to turn the starter in the engine. This requires a lot of power from the APU and is also quite noisy. On the 787, the engine start is entirely electrical.
Power is drawn from the APU and feeds the VFSGs in the engines. If you remember from earlier, these fist act as starter motors. The starter motor starts the turn the turbines in the middle of the engine. These in turn start to turn the forward stages of the engine. Once there is enough airflow through the engine, and the fuel is igniting, there is enough energy to continue running itself.
After start
Once the engine is running, the VFSGs stop acting as starter motors and revert to acting as generators. As these generators are the preferred power source, they automatically take over the running of the electrical systems from the APU, which can then be switched off. The aircraft is now in the desired configuration for flight, with the 4 VFSGs in both engines providing all the power the aircraft needs.
As the aircraft moves away towards the runway, another electrically powered system is used — the brakes. On other aircraft types, the brakes are powered by the hydraulics system. This requires extra pipe work and the associated weight that goes with that. Hydraulically powered brake units can also be time consuming to replace.
By having electric brakes, the 787 is able to reduce the weight of the hydraulics system and it also makes it easier to change brake units. “Plug in and play” brakes are far quicker to change, keeping maintenance costs down and reducing flight delays.
In-flight
Another system which is powered electrically on the 787 is the anti-ice system. As aircraft fly though clouds in cold temperatures, ice can build up along the leading edge of the wing. As this reduces the efficiency of the the wing, we need to get rid of this.
Other aircraft types use hot air from the engines to melt it. On the 787, we have electrically powered pads along the leading edge which heat up to melt the ice.
Not only does this keep more power in the engines, but it also reduces the drag created as the hot air leaves the structure of the wing. A double win for fuel savings.
Once on the ground at the destination, it’s time to start thinking about the electrical configuration again. As we make our way to the gate, we start the APU in preparation for the engine shut down. However, because the engine generators have a high priority than the APU generators, the APU does not automatically take over. Instead, an indication on the EICAS shows APU RUNNING, to inform us that the APU is ready to take the electrical load.
Shutdown
With the park brake set, it’s time to shut the engines down. A final check that the APU is indeed running is made before moving the engine control switches to shut off. Plunging the cabin into darkness isn’t a smooth move. As the engines are shut down, the APU automatically takes over the power supply for the aircraft. Once the ground staff have connected the external power, we then have the option to also shut down the APU.
However, before doing this, we consider the cabin environment. If there is no PCA available and it’s hot outside, without the APU the cabin temperature will rise pretty quickly. In situations like this we’ll wait until all the passengers are off the aircraft until we shut down the APU.
Once on external power, the full flight cycle is complete. The aircraft can now be cleaned and catered, ready for the next crew to take over.
Bottom line
Electricity is a fundamental part of operating the 787. Even when there are no passengers on board, some power is required to keep the systems running, ready for the arrival of the next crew. As we prepare the aircraft for departure and start the engines, various methods of powering the aircraft are used.
The aircraft has six electrical generators, of which only four are used in normal flights. Should one fail, there are back-ups available. Should these back-ups fail, there are back-ups for the back-ups in the form of the battery. Should this back-up fail, there is yet another layer of contingency in the form of the RAT. A highly unlikely event.
The 787 was built around improving efficiency and lowering carbon emissions whilst ensuring unrivalled levels safety, and, in the wider energy landscape, perspectives like nuclear beyond electricity highlight complementary paths to decarbonization — a mission it’s able to achieve on hundreds of flights every single day.
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.
Adams Nielson Solar Array, a 28 MW DC utility-scale project in Lind, WA, spans 200 acres with 81,700 panels, powering about 4,000 homes, supporting Avista’s Solar Select program and renewable energy, sustainability, and carbon reduction.
Key Points
Adams Nielson Solar Array is a 28 MW DC facility in Lind, WA, powering ~4,000 homes via Avista’s Solar Select.
✅ 81,700 panels across 200 acres in Eastern Washington
✅ Offsets emissions equal to removing 7,300 cars annually
✅ Collaboration by Avista, Strata Solar, WUTC, WSU Energy
Official commissioning of the Adams Nielson solar array located in Lind, WA occurred today. The 28 Megawatt DC array is comprised of 81,700 panels that span 200 acres and generates enough electricity to supply the equivalent of approximately 4,000 homes annually, similar to a new co-op solar project serving South Metro members.
“Avista’s interest in the development of Solar Select, a voluntary commercial solar program reflecting broader corporate adoption such as a corporate solar power plant commissioned by Arvato, is consistent with the Company’s ongoing commitment to provide customers with renewable energy choices at reasonable cost,” said Dennis Vermillion, president, Avista Corporation. “In recent years, an increasing number of Avista customers have expressed their expectations and challenges in acquiring renewable energy. Avista is pleased to lead this effort and develop renewable energy products that meet our customers’ needs today and into the future.” This interest is being generated by a mix of local and national customers across a variety of industries, including Huckleberry’s, Gonzaga University, Community Colleges of Spokane, Hotstart, Central Pre-Mix Concrete, a CRH Co., independently owned McDonald's franchise locations, Spokane City, Main Market and Community Building and VA Medical Center.
Jim Simon, director of sustainability at Gonzaga University said, “The Solar Select program helps Gonzaga University move even closer to achieving its goal of climate neutrality by 2050 by continuing to prioritize renewables in our energy portfolio, as other communities add projects like a municipal solar project to boost local supply. We are grateful for Avista’s leadership in this project and look forward to other opportunities to reduce our greenhouse gas emissions.”
Spokane Mayor David Condon said, “The City of Spokane is pleased to partner with Avista through the Solar Select Program, as we continue to seek out opportunities that are both environmentally and financially responsible. The City already is a net producer of energy, generating more clean, green energy than our use of electricity, natural gas, and fuel, a milestone also seen with North Carolina's first wind farm now fully operational. We are excited to add even more clean energy to power City Hall.”
The Solar Select program created a cost-effective structure to bring solar energy to large business customers in Eastern Washington, allowing them to advance their desired sustainability goals and benefiting from industry service innovations led by companies like Omnidian expanding their global reach. The array is projected to deliver the environmental benefit equivalent of more than 7,300 cars removed from the road each year. This renewable energy program was made possible through a collaboration of Avista, Strata Solar, the Washington Utilities and Transportation Commission, and the WSU Energy Program.
