Some technical standards might require bigger engines than necessary for an operation. I want to share with you the phenomenon of “the bigger, the better,” as personally experienced by me.
When I grew up, my parents, three children and our grandmother shared a home of 1,400 square feet with three bedrooms. The three children shared one bedroom — not a lot of privacy, but we all grew up well. One became a brigadier general, one became a doctor, and one became a pilot. None of us can recall being crowded or restricted.
When I got married in the 80s, we bought a home of 2,400 square feet with three bedrooms, which looked huge at the time. By the time we had children, we moved to a 5,000-square-foot home with five bedrooms and four bathrooms and a pool that I may use only five to six times a year. We live in Toronto. How did we end up in this big place? I think it is what we call peer pressure: buying and spending on things we donÂ’t really need or use most of the time.
How is this story related to GPU technology? Let me tell you.
We manufacture GPU products according to demands expressed through purchase orders issued by end users. We develop and introduce new products, mainly to fulfill the customersÂ’ requirements.
Normally, customer requirements will originate with the specification published by aircraft manufacturers. From there, an evaluation of other local requirements such as aircraft mix on the apron, weather, available facilities, etc., will be taken into account. On the other hand, GPU manufacturers will offer products that are designed and built to meet various standards, mostly related to the quality and specifications of the electrical output, safety requirements for structure, operations and the requirements related to pollution factors of noise, emission and hazardous materials. Up to this point, it all makes good sense from every point of view.
When these processes are implemented through various publications of specifications and in trying to cover for every possibility — as remote as it may be — we end up with “the bigger, the better” syndrome. The details are buried in the “small print” and in certain situations, as described further below, it brings about legitimate questions of cross purpose.
Take, for example, the standards associated with “frequency stability,” which are designed to ensure the supply of current frequency with minimum fluctuations. To this day, MIL-STD-704E still provides the basic platform for GPU design for the frequency fluctuations during transient load episode (going either up or down); i.e., maximum destabilized frequency fluctuation of ± 25Hz at the onset of the transient episode, decreasing to ± 7Hz within 10 seconds.
Technology advancements in the electrical functions of newer aircraft drives the demand for higher accuracy of the current supply, so we aspire to further narrow the regulation of frequency fluctuations to a maximum of ± 15Hz at the onset of the transient episode, decreasing to ± 4Hz within two seconds. as per SAE publication APR5015. So far so good.
However, in the same document, APR5015, the above improvement in frequency tolerances is also accompanied by the recommendation for increasing the load envelope of controlled frequency regulation. In fact, the publication recommends for 100-percent load envelope, i.e., the requirement for frequency regulation is to perform during transient loads equal to the full rated capacity of the unit. Just to make this clear, it means that a GPU rated at 90 kva is required to maintain its frequency regulated at the above-mentioned rate during a load transient from 100-percent power to 0-percent power and back to 100-percent power. Here is where I question the wisdom and the practical basis for the APR5015 demand.
An airline analogy for comparison would be an FAA standard requiring the airlines to widen all seats in the aircraft by 33 percent to accommodate heavyset persons that may or may not come on the flight.
Since that same standard, SAE-APR5015, is now recommending that GPUs should not be used to clear aircraft electrical faults and we have done away with the requirement for 150-percent overload capability, I canÂ’t imagine any practical occurrences where a GPU will be under a full load and then lose it and then immediately regain it; or alternatively, where a GPU will be connected to an aircraft that will instantaneously demand a full load from the GPU.
The reality is that the operator/user is now buying GPUs with engines that are bigger by some 33 percent than before, just to be able to comply with this requirement.
Example? The manufacturer of a GPU rated for 120 kva will have to use an engine that will provide at least 170 kva (215 hp) in order to accommodate sufficient margining for full compliance. If you are curious, this is how it looks for some other GPU sizes:
• rated: 180 kva; engine required: 325 hp (256 kva)
• rated: 140 kva; engine required: 276 hp (217 kva)
• rated: 90 kva; engine required: 100 hp (128 kva)
Who is paying? Mainly the airlines. In addition, the environment; so we all pay.
Nord Stream Pipeline Sabotage triggers Baltic Sea gas leaks as Norway and Denmark tighten energy infrastructure security, offshore surveillance, and exclusion zones, after drone sightings near platforms and explosions reported by experts.
Key Points
An alleged attack causing Baltic gas leaks and heightened energy security measures in Norway and Denmark.
✅ Norway boosts offshore and onshore site security
✅ Denmark enforces 5 nm exclusion zone near leaks
✅ Drones spotted; police probe sabotage and safety breaches
Norway and Denmark will increase security and surveillance around their energy infrastructure sites after the alleged sabotage of Russia's Nord Stream gas pipeline in the Baltic Sea, as the EU pursues a plan to dump Russian energy to safeguard supplies.
Major leaks struck two underwater natural gas pipelines running from Russia to Germany, which has moved to a 200 billion-euro energy shield amid surging prices, with experts reporting that explosions rattled the Baltic Sea beforehand.
Norway -- an oil-rich nation and Europe's biggest supplier of gas -- will strengthen security at its land and offshore installations, even as it weighs curbing electricity exports to avoid shortages, the country's energy minister said.
The Scandinavian country's Petroleum Safety Authority also urged vigilance on Monday after unidentified drones were seen flying near Norway's offshore oil and gas platforms.
"The PSA has received a number of warnings/notifications from operator companies on the Norwegian Continental Shelf concerning the observation of unidentified drones/aircraft close to offshore facilities" the agency said in a statement.
"Cases where drones have infringed the safety zone around facilities are now being investigated by the Norwegian police."
Meanwhile Denmark will increase security across its energy sector after the Nord Stream incident, as wider market strains, including Germany's struggling local utilities, ripple across Europe, a spokesperson for gas transmission operator Energinet told Upstream.
The Danish Maritime Agency has also imposed an exclusion zone for five nautical miles around the leaks, warning ships of a danger they could lose buoyancy, and stating there is a risk of the escaping gas igniting "above the water and in the air," even as Europe weighs emergency electricity measures to limit prices.
Denmark's defence minister said there was no cause for security concerns in the Baltic Sea region.
"Russia has a significant military presence in the Baltic Sea region and we expect them to continue their sabre-rattling," Morten Bodskov said in a statement.
Video taken by a Danish military plane on Tuesday afternoon showed the extent of one of gas pipeline leaks, with the surface of the Baltic bubbling up as gas escapes, highlighting Europe's energy crisis for global audiences:
Meanwhile police in Sweden have opened a criminal investigation into "gross sabotage" of the Nord Stream 1 and Nord Stream 2 pipelines, and Sweden's crisis management unit was activated to monitor the situation. The unit brings together representatives from different government agencies.
Swedish Foreign Minister Ann Linde had a call with her Danish counterpart Jeppe Kofod on Tuesday evening, and the pair also spoke with Norwegian Foreign Minister Anniken Huitfeldt on Wednesday, as the bloc debates gas price cap strategies to address the crisis, with Kofod saying there should be a "clear and unambiguous EU statement about the explosions in the Baltic Sea."
"Focus now on uncovering exactly what has happened - and why. Any sabotage against European energy infrastructure will be met with a robust and coordinated response," said Kofod.
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.
Fukushima Hydrogen Energy System leverages a 10,000 kW H2 production hub for grid balancing, demand response, and renewable integration, delivering hydrogen supply across Tohoku while supporting storage, forecasting, and flexible power management.
Key Points
A 10,000 kW H2 project in Namie for grid balancing, renewable integration, and regional hydrogen supply.
✅ 10,000 kW H2 production hub in Namie, Fukushima
✅ Balances renewable-heavy grids via demand response
✅ Supported by NEDO; partners Toshiba, Tohoku Electric, Iwatani
Toshiba Corporation, Tohoku Electric Power Co. and Iwatani Corporation have announced they will construct and operate a large-scale hydrogen (H2) energy system in Japan, based on a 10,000 kilowat class H2 production facility, which reflects advances in PEM hydrogen R&D worldwide.
The system, which will be built in Namie-Cho, Fukushima, will use H2 to offset grid loads and deliver H2 to locations in Tohoku and beyond, while complementary approaches like power-to-gas storage in Europe demonstrate broader storage options, and will seek to demonstrate the advantages of H2 as a solution in grid balancing and as a H2 gas supply.
The product has won a positive evaluation from Japan’s New Energy and Industrial Technology Development Organisation (NEDO), and its continued support for the transition to the technical demonstration phase. The practical effectiveness of the large-scale system will be determined by verification testing in financial year 2020, even as interest grows in nuclear beyond electricity for complementary services.
The main objectives of the partners are to promote expanded use of renewable energy in the electricity grid, including UK offshore wind investment by Japanese utilities, in order to balance supply and demand and process load management; and to realise a new control system that optimises H2 production and supply with demand forecasting for H2.
Hiroyuki Ota, General Manager of Toshiba’s Energy Systems and Solutions Company, said, “Through this project, Toshiba will continue to provide comprehensive H2 solutions, encompassing all processes from the production to utilisation of hydrogen.”
Manager of Tohoku Electric Power Co., Ltd, Mitsuhiro Matsumoto, added, “We will study how to use H2 energy systems to stabilize electricity grids with the aim of increasing the use of renewable energy and contributing to Fukushima.”
Moriyuki Fujimoto, General Manager of Iwatani Corporation, commented, “Iwatani considers that this project will contribute to the early establishment of a H2 economy that draws on our experience in the transportation, storage and supply of industrial H2, and the construction and operation of H2stations.”
Japan’s Ministry of Economy, Trade and Industry’s ‘Long-term Energy Supply and Demand Outlook’ targets increasing the share of renewable energy in Japan’s overall power generation mix from 10.7% in 2013 to 22-24% by 2030. Since output from renewable energy sources is intermittent and fluctuates widely with the weather and season, grid management requires another compensatory power source, as highlighted by a near-blackout event in Japan. The large hydrogen energy system is expected to provide a solution for grids with a high penetration of renewables.
National Grid Demand Flexibility Service helps stabilise the UK grid during tight supply, offering discounts for smart meter users who shift peak-time electricity use, reducing power cut risks amid low wind and import constraints.
Key Points
A National Grid scheme paying smart homes to cut peak-time use, easing supply pressure and avoiding power cuts.
✅ Pays volunteers with smart meters to reduce peak demand.
✅ Credits discounts for shifting use to off-peak windows.
✅ Manages tight margins and helps avert UK power cuts.
National Grid has decided not to activate a scheme on Tuesday to help the UK avoid power cuts after being poised to do so.
It would have seen some households offered discounts on their electricity bills if they cut peak-time use.
National Grid had been ready to trigger the scheme following a warning that Britain's energy supplies were looking tighter than usual this week.
However, it decided that the measure was not required.
Alerts are sent out automatically when expected supplies drop below a certain level. But they do not mean that blackouts are likely, or that the situation is critical.
National Grid said it was "confident" it would be able to manage margins and "demand is not at risk".
Discounts Earlier on Monday, the grid operator said it was considering whether to pay households across Britain to reduce their energy use to help out on Tuesday evening.
Under the Demand Flexibility Service (DFS), announced earlier this month, customers that have signed up could get discounts on their bills if they use less electricity in a given window of time.
That could mean delaying the use of a tumble-dryer or washing machine, or cooking dinner in the microwave rather than the oven.
Major suppliers such as Octopus and British Gas are taking part, but only customers that have an electricity smart meter and that have volunteered are eligible. About 14 million UK homes have an electricity smart meter.
The DFS has already been tested twice but has not yet run live.
Octopus, the supplier with the most customers signed up, said that some households had earned more than £4 during the hour-long tests, while the average saving was "well over £1".
It came after forecasts projected a large drop in the amount of power that Britain will be able to import from French nuclear power stations on Monday and Tuesday evenings.
The lack of strong winds to power turbines has also affected how much power can be generated within the UK, and efforts to fast-track grid connections aim to ease constraints.
Such warnings are not unusual - around 12 have been issued and cancelled without issue in the last six years, and other regions such as Canada are seeing grids strained by harsh weather as well.
However, they have become more common this year due to the energy crisis, and the most recent notice was sent out last week.
The situation means that the UK will have to import electricity from other sources on Monday and Tuesday evening.
Supplies are also expected be tight in France, forecasters say.
France has been facing months of problems with its nuclear power plants, which generate around three-quarters of the country's electricity.
More than half of the nuclear reactors run by state energy company EDF have closed due to maintenance problems and technical issues.
It has added to a massive energy crisis in Europe which is facing a winter without gas supplies from Russia.
New York Renewable Energy Contracts secure 23 projects totaling 2.3 GW, spanning offshore wind, solar, and battery storage under CLCPA goals, advancing 70% by 2030, a carbon-free 2040 grid, grid reliability, and green jobs.
Key Points
State agreements securing 23 wind, solar, and storage projects (2.3 GW) to meet CLCPA clean power targets.
✅ 2.3 GW across 23 wind, solar, and storage projects statewide
✅ Supports 70% renewables by 2030; carbon-free grid by 2040
✅ Drives emissions cuts, grid reliability, and green jobs
In a significant milestone for the state’s clean energy ambitions, New York has finalized contracts with 23 renewable energy projects, as part of large-scale energy projects underway in New York, totaling a combined capacity of 2.3 gigawatts (GW). This move is part of the state’s ongoing efforts to accelerate its transition to renewable energy, reduce carbon emissions, and meet the ambitious targets set under the Climate Leadership and Community Protection Act (CLCPA), which aims to achieve a carbon-free electricity grid by 2040.
A Strong Commitment to Renewable Energy
The 23 projects secured under these contracts represent a diverse range of renewable energy sources, including wind, solar, and battery storage. Together, these projects are expected to contribute significantly to New York’s energy grid, generating enough clean electricity to power millions of homes. The deal is a key component of New York’s broader strategy to achieve a 70% renewable energy share in the state’s electricity mix by 2030 and to reduce greenhouse gas emissions by 85% by 2050.
Governor Kathy Hochul celebrated the agreements as a major step forward in the state’s commitment to combating climate change while creating green jobs and economic opportunities. “New York is leading the nation in its clean energy goals, and these projects will help us meet our bold climate targets while delivering reliable and affordable energy to New Yorkers,” Hochul said in a statement.
The Details of the Contracts
The 23 projects span across various regions of the state, with an emphasis on areas that are well-suited for renewable energy development, such as upstate New York, which boasts vast open spaces ideal for large-scale solar and wind installations and the state is investigating sites for offshore wind projects along the coast. The contracts finalized by the state will ensure a steady supply of clean power from these renewable sources, helping to stabilize the grid and reduce reliance on fossil fuels.
A significant portion of the new renewable capacity will come from offshore wind projects, which have become a cornerstone of New York’s renewable energy strategy. Offshore wind has the potential to provide large amounts of electricity, and the state recently greenlighted the country's biggest offshore wind farm to date, taking advantage of the state's proximity to the Atlantic Ocean. Several of the contracts finalized include offshore wind farm projects, which are expected to be operational within the next few years.
In addition to wind energy, solar power continues to be a critical component of the state’s renewable energy strategy. The state has already made substantial investments in solar energy, having achieved solar energy goals ahead of schedule recently, and these new contracts will further expand the state’s solar capacity. The inclusion of battery storage projects is another important element, as energy storage solutions are vital to ensuring that renewable energy can be effectively utilized, even when the sun isn’t shining or the wind isn’t blowing.
Economic and Job Creation Benefits
The finalization of these 23 contracts will not only bring significant environmental benefits but also create thousands of jobs in the renewable energy sector. Construction, maintenance, and operational jobs will be generated throughout the life of the projects, benefiting communities across the state, including areas near Long Island's South Shore wind proposals that stand to gain from new investment. The investment in renewable energy is expected to support New York’s recovery from the economic impacts of the COVID-19 pandemic, contributing to the state’s clean energy economy and providing long-term economic stability.
The state's focus on clean energy also provides opportunities for local businesses, highlighted by the first Clean Energy Community designation in the state, as many of these projects will require services and materials from within New York State. Additionally, Governor Hochul’s administration has made efforts to ensure that disadvantaged communities and workers from underrepresented backgrounds will have access to job training and employment opportunities within the renewable energy sector.
The Path Forward: A Clean Energy Future
New York’s aggressive move toward renewable energy is indicative of the state’s commitment to addressing climate change and leading the nation in clean energy innovation. By locking in contracts for these renewable energy projects, the state is not only securing a cleaner future but also ensuring that the transition is fair and just for all communities, particularly those that have been historically impacted by pollution and environmental degradation.
While the finalized contracts mark a major achievement, the state’s work is far from over. The completion of these 23 projects is just one piece of the puzzle in New York’s broader strategy to decarbonize its energy system. To meet its ambitious targets under the CLCPA, New York will need to continue investing in renewable energy, energy storage, grid modernization, and energy efficiency programs.
As New York moves forward with its clean energy transition, and as BOEM receives wind power lease requests in the Northeast, the state will likely continue to explore new technologies and innovative solutions to meet the growing demand for renewable energy. The success of the 23 finalized contracts serves as a reminder of the state’s leadership in the clean energy space and its ongoing efforts to create a sustainable, low-carbon future for all New Yorkers.
New York’s decision to finalize contracts with 23 renewable energy projects totaling 2.3 gigawatts represents a bold step toward meeting the state’s clean energy and climate goals. These projects, which include a mix of wind, solar, and energy storage, will contribute significantly to reducing the state’s reliance on fossil fuels and lowering greenhouse gas emissions. With the additional benefits of job creation and economic growth, this move positions New York as a leader in the nation’s transition to renewable energy and a sustainable future.
Bruce Power Unit 6 refurbishment replaces major reactor components, shifting supply to hydroelectric and natural gas, sustaining Ontario jobs, extending plant life to 2064, and managing radioactive waste along Lake Huron, on-time and on-budget.
Key Points
A 4-year, $2.1B reactor overhaul within a 13-year, $13B program to extend plant life to 2064 and support Ontario jobs.
✅ Unit 6 offline 4 years; capacity shift to hydro and gas
✅ Part of 13-year, $13B program; extends life to 2064
✅ Creates jobs; manages radioactive waste at Lake Huron
The world’s largest nuclear fleet, became a little smaller Monday morning. Bruce Power has began the process to take Unit 6 offline to begin a $2.1 billion project, supported by manufacturing contracts with key suppliers, to replace all the major components of the reactor.
The reactor, which produces enough electricity to power 750,000 homes and reflects higher output after upgrades across the site, will be out of service for the next four years.
In its place, hydroelectric power and natural gas will be utilized more.
Taking Unit 6 offline is just the “official” beginning of a 13-year, $13-billion project to refurbish six of Bruce Power’s eight nuclear reactors, as Ontario advances the Pickering B refurbishment as well on its grid.
Work to extend the life of the nuclear plant started in 2016, and the company recently marked an operating record while supporting pandemic response, but the longest and hardest part of the project - the major component replacement - begins now.
“The Unit 6 project marks the next big step in a long campaign to revitalize this site,” says Mike Rencheck, Bruce Power’s president and CEO.
The overall project is expected to last until 2033, and mirrors life extensions at Pickering supporting Ontario’s zero-carbon goals, but will extend the life of the nuclear plant until 2064.
Extending the life of the Bruce Power nuclear plant will sustain 22,000 jobs in Ontario and add $4 billion a year in economic activity to the province, say Bruce Power officials.
About 2,000 skilled tradespeople will be required for each of the six reactor refurbishments - 4,200 people already work at the sprawling nuclear plant near Kincardine.
It will also mean tons of radioactive nuclear waste will be created that is currently stored in buildings on the Bruce Power site, along the shores of Lake Huron.
Bruce Power restarted two reactors back in 2012, and in later years doubled a PPE donation to support regional health partners. That project was $2-billion over-budget, and three years behind schedule.
Bruce Power officials say this refurbishment project is currently on-time and on-budget.
