EPA reveals 44 higher risk coal ash sites

Sulphur Hexafluoride (SF6) Emissions drive rising greenhouse gas impacts in electrical switchgear, power grids, and renewables, with extreme global warming potential, long atmospheric lifetime, and leakage risks challenging climate targets and grid decarbonization.

Key Points

SF6 emissions are leaks from electrical switchgear and grids, a high-GWP gas with ~1,000-year lifetime.

✅ 23,500x CO2 global warming potential (GWP)

✅ Leaks from switchgear, breakers, gas-insulated substations

✅ Clean air and vacuum alternatives emerging for MV/HV

Sulphur hexafluoride, or SF6, is widely used in the electrical industry to prevent short circuits and accidents.

But leaks of the little-known gas in the UK and the rest of the EU in 2017 were the equivalent of putting an extra 1.3 million cars on the road.

Levels are rising as an unintended consequence of the green energy boom and the broader global energy transition worldwide.

Cheap and non-flammable, SF6 is a colourless, odourless, synthetic gas. It makes a hugely effective insulating material for medium and high-voltage electrical installations.

It is widely used across the industry, from large power stations to wind turbines to electrical sub-stations in towns and cities.

It prevents electrical accidents and fires.

However, the significant downside to using the gas is that it has the highest global warming potential of any known substance. It is 23,500 times more warming than carbon dioxide (CO2).

Just one kilogram of SF6 warms the Earth to the same extent as 24 people flying London to New York return.

It also persists in the atmosphere for a long time, warming the Earth for at least 1,000 years.

So why are we using more of this powerful warming gas?

The way we make electricity around the world is changing rapidly, with New Zealand's push to electrify in its energy system.

Where once large coal-fired power stations brought energy to millions, the drive to combat climate change and to move away from coal means they are now being replaced by mixed sources of power including wind, solar and gas.

This has resulted in many more connections to the electricity grid, and with EU electricity use could double by 2050, a rise in the number of electrical switches and circuit breakers that are needed to prevent serious accidents.

Collectively, these safety devices are called switchgear. The vast majority use SF6 gas to quench arcs and stop short circuits.

"As renewable projects are getting bigger and bigger, we have had to use it within wind turbines specifically," said Costa Pirgousis, an engineer with Scottish Power Renewables on its new East Anglia wind farm, which doesn't use SF6 in turbines.

"As we are putting in more and more turbines, we need more and more switchgear and, as a result, more SF6 is being introduced into big turbines off shore.

"It's been proven for years and we know how it works, and as a result it is very reliable and very low maintenance for us offshore."

How do we know that SF6 is increasing?

Across the entire UK network of power lines and substations, there are around one million kilograms of SF6 installed.

A study from the University of Cardiff found that across all transmission and distribution networks, the amount used was increasing by 30-40 tonnes per year.

This rise was also reflected across Europe with total emissions from the 28 member states in 2017 equivalent to 6.73 million tonnes of CO2. That's the same as the emissions from 1.3 million extra cars on the road for a year.

Researchers at the University of Bristol who monitor concentrations of warming gases in the atmosphere say they have seen significant rises in the last 20 years.

"We make measurements of SF6 in the background atmosphere," said Dr Matt Rigby, reader in atmospheric chemistry at Bristol.

"What we've seen is that the levels have increased substantially, and we've seen almost a doubling of the atmospheric concentration in the last two decades."

How does SF6 get into the atmosphere?

The most important means by which SF6 gets into the atmosphere is from leaks in the electricity industry.

Electrical company Eaton, which manufactures switchgear without SF6, says its research indicates that for the full life-cycle of the product, leaks could be as high as 15% - much higher than many other estimates.

Louis Schaeffer, electrical business manager at Eaton, said: "The newer gear has very low leak rates but the key question is do you have newer gear?

"We looked at all equipment and looked at the average of all those leak rates, and we didn't see people taking into account the filling of the gas. Plus, we looked at how you recycle it and return it and also included the catastrophic leaks."

How damaging to the climate is this gas?

Concentrations in the atmosphere are very small right now, just a fraction of the amount of CO2 in the air.

However, the global installed base of SF6 is expected to grow by 75% by 2030, as data-driven electricity demand surges worldwide.

Another concern is that SF6 is a synthetic gas and isn't absorbed or destroyed naturally. It will all have to be replaced and destroyed to limit the impact on the climate.

Developed countries are expected to report every year to the UN on how much SF6 they use, but developing countries do not face any restrictions on use.

Right now, scientists are detecting concentrations in the atmosphere that are 10 times the amount declared by countries in their reports. Scientists say this is not all coming from countries like India, China and South Korea.

One study found that the methods used to calculate emissions in richer countries "severely under-reported" emissions over the past two decades.

Why hasn't this been banned?

SF6 comes under a group of human-produced substances known as F-gases. The European Commission tried to prohibit a number of these environmentally harmful substances, including gases in refrigeration and air conditioning, back in 2014.

But they faced strong opposition from industries across Europe.

"In the end, the electrical industry lobby was too strong and we had to give in to them," said Dutch Green MEP Bas Eickhout, who was responsible for the attempt to regulate F-gases.

"The electric sector was very strong in arguing that if you want an energy transition, and you have to shift more to electricity, you will need more electric devices. And then you also will need more SF6.

"They used the argument that otherwise the energy transition would be slowed down."

What do regulator and electrical companies say about the gas?

Everyone is trying to reduce their dependence on the gas, and US control efforts suggest targeted policies can drive declines, as it is universally recognised as harmful to the climate.

In the UK, energy regulator Ofgem says it is working with utilities to try to limit leaks of the gas.

"We are using a range of tools to make sure that companies limit their use of SF6, a potent greenhouse gas, where this is in the interest of energy consumers," an Ofgem spokesperson told BBC News.

"This includes funding innovation trials and rewarding companies to research and find alternatives, setting emissions targets, rewarding companies that beat those targets, and penalising those that miss them."

Are there alternatives - and are they very expensive?

The question of alternatives to SF6 has been contentious over recent years.

For high-voltage applications, experts say there are very few solutions that have been rigorously tested.

"There is no real alternative that is proven," said Prof Manu Haddad from the school of engineering at Cardiff University.

"There are some that are being proposed now but to prove their operation over a long period of time is a risk that many companies don't want to take."

Medium voltage operations there are several tried-and-tested materials. Some in the industry say that the conservative nature of the electrical industry is the key reason that few want to change to a less harmful alternative.

"I will tell you, everyone in this industry knows you can do this; there is not a technical reason not to do it," said Louis Schaffer from Eaton.

"It's not really economic; it's more a question that change takes effort and if you don't have to, you won't do it."

Some companies are feeling the winds of change

Sitting in the North Sea some 43km from the Suffolk coast, Scottish Power Renewables has installed one of world's biggest wind farms, in line with a sustainable electric planet vision, where the turbines will be free of SF6 gas.

East Anglia One will see 102 of these towering generators erected, with the capacity to produce up to 714MW (megawatts) of power by 2020, enough to supply half a million homes.

Previously, an installation like this would have used switchgear supplied with SF6, to prevent the electrical accidents that can lead to fires.

Each turbine would normally have contained around 5kg of SF6, which, if it leaked into the atmosphere, would add the equivalent of around 117 tonnes of carbon dioxide. This is roughly the same as the annual emissions from 25 cars.

"In this case we are using a combination of clean air and vacuum technology within the turbine. It allows us to still have a very efficient, reliable, high-voltage network but to also be environmentally friendly," said Costa Pirgousis from Scottish Power Renewables.

"Once there are viable alternatives on the market, there is no reason not to use them. In this case, we've got a viable alternative and that's why we are using it."

But even for companies that are trying to limit the use of SF6, there are still limitations. At the heart of East Anglia One sits a giant offshore substation to which all 102 turbines will connect. It still uses significant quantities of the highly warming gas.

What happens next ?

The EU will review the use of SF6 next year and will examine whether alternatives are available. However, even the most optimistic experts don't think that any ban is likely to be put in place before 2025.

Hydro-Quebec hydropower exports deliver low-carbon electricity to New England, sparking debate on greenhouse gas accounting, grid attributes, and REC-style certificates as Quebec modernizes monitoring to verify emissions, integrate renewables, and meet ambitious climate targets.

Key Points

Low-carbon electricity to New England, with improved emissions tracking and verifiable grid attributes.

✅ Deep, narrow reservoirs cut lifecycle GHGs in cold boreal waters

✅ Attribute certificates trace source, type, and carbon intensity

✅ Contracts require facility-level tagging for compliance

For 40 years, through the most vicious interprovincial battles, even as proposals for bridging the Alberta-B.C. gap aimed to improve grid resilience, Canadians could agree on one way Quebec is undeniably superior to the rest of the country.

It’s hydropower, and specifically the mammoth dam system in Northern Quebec that has been paying dividends since it was first built in the 70s. “Quebec continues to boast North America’s lowest electricity prices,” was last year’s business-as-usual update in one trade publication, even as Newfoundland's rate strategy seeks relief for consumers.

With climate crisis looming, that long-ago decision earns even more envy and reflects Canada's electricity progress across the grid today. Not only do they pay less, but Quebeckers also emit the least carbon per capita of any province.

It may surprise most Canadians, then, to hear how most of New England has reacted to the idea of being able to buy permanently into Quebec’s power grid.

​​​​​​Hydro-Québec’s efforts to strike major export deals have been rebuffed in the U.S., by environmentalists more than anyone. They question everything about Quebec hydropower, including asking “is it really low-carbon?”

These doubts may sound nonsensical to regular Quebeckers. But airing them has, in fact, pushed Hydro-Québec to learn more about itself and adopt new technology.

We know far more about hydropower than we knew 40 years ago, including whether it’s really zero-emission (it’s not), how to make it as close to zero-emission as possible, and how to account for it as precisely as new clean energies like solar and wind, underscoring how cleaning up Canada's electricity is vital to meeting climate pledges.

The export deals haven’t gone through yet, but they’ve already helped drag Hydro-Québec—roughly the fourth-biggest hydropower system on the planet—into the climate era.

Fighting to export
One of the first signs of trouble for Quebec hydro was in New Hampshire, almost 10 years ago. People there began pasting protest signs on their barns and buildings. One citizens’ group accused Hydro of planning a “monstrous extension cord” across the state.

Similar accusations have since come from Maine, Massachusetts and New York.

The criticism isn’t coming from state governments, which mostly want a more permanent relationship with Hydro-Québec. They already rely on Quebec power, but in a piecemeal way, topping up their own power grid when needed (with the exception of Vermont, which has a small permanent contract for Quebec hydropower).

Last year, Quebec provided about 15 percent of New England’s total power, plus another substantial amount to New York, which is officially not considered to be part of New England, and has its own energy market separate from the New England grid.

Now, northeastern states need an energy lynch pin, rather than a top-up, with existing power plants nearing the end of their lifespans. In Massachusetts, for example, one major nuclear plant shut down this year and another will be retired in 2021. State authorities want a hydro-based energy plan that would send $10 billion to Hydro-Québec over 20 years.

New England has some of North America’s most ambitious climate goals, with every state in the region pledging to cut emissions by at least 80 percent over the next 30 years.

What’s the downside? Ask the citizens’ groups and nonprofits that have written countless op-eds, organized petitions and staged protests. They argue that hydropower isn’t as clean as cutting-edge clean energy such as solar and wind power, and that Hydro-Québec isn’t trying hard enough to integrate itself into the most innovative carbon-counting energy system. Right as these other energy sources finally become viable, they say, it’s a step backwards to commit to hydro.

As Hydro-Québec will point out, many of these critics are legitimate nonprofits, but others may have questionable connections. The Portland Press Herald in Maine reported in September 2018 that a supposedly grassroot citizens’ group called “Stand Up For Maine” was actually funded by the New England Power Generators Association, which is based in Boston and represents such power plant owners as Calpine Corp., Vistra Energy and NextEra Energy.

But in the end, that may not matter. Arguably the biggest motivator to strike these deals comes not from New England’s needs, but from within Quebec. The province has spent more than $10 billion in the last 15 years to expand its dam and reservoir system, and in order to stay financially healthy, it needs to double its revenue in the next 10 years—a plan that relies largely on exports.

With so much at stake, it has spent the last decade trying to prove it can be an energy of the future.

“Learning as you go”
American critics, justified or not, have been forcing advances at Hydro for a long time.

When the famously huge northern Quebec hydro dams were built at James Bay—construction began in the early 1970s—the logic was purely economic. The term “climate change” didn’t exist. The province didn’t even have an environment department.

The only reason Quebec scientists started trying to measure carbon emissions from hydro reservoirs was “basically because of the U.S.,” said Alain Tremblay, a senior environmental advisor at Hydro Quebec.

In the early 1990s, Hydro began to export power to the U.S., and “because we were a good company in terms of cost and efficiency, some Americans didn't like that,” he said—mainly competitors, though he couldn’t say specifically who. “They said our reservoirs were emitting a lot of greenhouse gases.”

The detractors had no research to back up that claim, but Hydro-Québec had none to refute it, either, said Tremblay. “At that time we didn’t have any information, but from back-of-the envelope calculations, it was impossible to have the emissions the Americans were expecting we have.”

So research began, first to design methods to take the measurements, and then to carry them out. Hydro began a five-year project with a Quebec university.

It took about 10 years to develop a solid methodology, Tremblay said, with “a lot of error and learning-as-you-go.” There have been major strides since then.

“Twenty years ago we were taking a sample of water, bringing it back to the lab and analyzing that with what we call a gas chromatograph,” said Tremblay. “Now, we have an automated system that can measure directly in the water,” reading concentrations of CO2 and methane every three hours and sending its data to a processing centre.

The tools Hydro-Québec uses are built in California. Researchers around the world now follow the same standard methods.

At this point, it’s common knowledge that hydropower does emit greenhouse gases. Experts know these emissions are much higher than previously thought.

​But Hydro-Québec now has the evidence, also, to rebut the original accusations from the early 1990s and many similar ones today.

“All our research from Université Laval [found] that it’s about a thousand years before trees decompose in cold Canadian waters,” said Tremblay.

Hydro reservoirs emit greenhouse gases because vegetation and sometimes other biological materials, like soil runoff, decay under the surface.

But that decay depends partly on the warmth of the water. In tropical regions, including the southern U.S., hydro dams can have very high emissions. But in boreal zones like northern Quebec (or Manitoba, Labrador and most other Canadian locations with massive hydro dams), the cold, well-oxygenated water vastly slows the process.

Hydro emissions have “a huge range,” said Laura Scherer, an industrial ecology professor at Leiden University in the Netherlands who led a study of almost 1,500 hydro dams around the world.

“It can be as low as other renewable energy sources, but it can also be as high as fossil fuel energy,” in rare cases, she said.

While her study found that climate was important, the single biggest factor was “sizing and design” of each dam, and specifically its shape, she said. Ideally, hydro dams should be deep and narrow to minimize surface area, perhaps using a natural valley.

Hydro-Québec’s first generation of dams, the ones around James Bay, were built the opposite way—they’re wide and shallow, infamously flooding giant tracts of land.

Newly built ones take that new information into account, said Tremblay. Its most recent project is the Romaine River complex, which will eventually include four reservoirs near Quebec’s northeastern border with Labrador. Construction began in 2016.

The site was picked partly for its topography, said Tremblay.

“It’s a valley-type reservoir, so large volume, small surface area, and because of that there’s a pretty limited amount of vegetation that’s going to be flooded,” he said.

There’s a dramatic emissions difference with the project built just before that, commissioned in 2006. Called Eastmain, it’s built near James Bay.

“The preliminary results indicate with the same amount of energy generated [by Romaine] as with Eastmain, you’re going to have about 10 times less emissions,” said Tremblay.

Tracing energy to its source
These signs of progress likely won’t satisfy the critics, who have publicly argued back and forth with Hydro about exactly how emissions should be tallied up.

But Hydro-Québec also faces a different kind of growing gap when it comes to accounting publicly for its product. In the New England energy market, a sophisticated system “tags” all the energy in order to delineate exactly how much comes from which source—nuclear, wind, solar, and others—and allows buyers to single out clean power, or at least the bragging rights to say they bought only clean power.

Really, of course, it’s all the same mix of energy—you can’t pick what you consume. But creating certificates prevents energy producers from, in worst-case scenarios, being able to launder regular power through their clean-power facilities. Wind farms, for example, can’t oversell what their own turbines have produced.

What started out as a fraud prevention tool has “evolved to make it possible to also track carbon emissions,” said Deborah Donovan, Massachusetts director at the Acadia Center, a climate-focused nonprofit.

But Hydro-Québec isn’t doing enough to integrate itself into this system, she says.

It’s “the tool that all of our regulators in New England rely on when we are confirming to ourselves that we’ve met our clean energy and our carbon goals. And…New York has a tool just like that,” said Donovan. “There isn’t a tracking system in Canada that’s comparable, though provinces like Nova Scotia are tapping the Western Climate Initiative for technical support.”

Developing this system is more a question of Canadian climate policy than technology.

Energy companies have long had the same basic tracking device—a meter, said Tanya Bodell, a consultant and expert in New England’s energy market. But in New England, on top of measuring “every time there’s a physical flow of electricity” from a given source, said Bodell, a meter “generates an attribute or a GIS certificate,” which certifies exactly where it’s from. The certificate can show the owner, the location, type of power and its average emissions.

Since 2006, Hydro-Québec has had the ability to attach the same certificates to its exports, and it sometimes does.

“It could be wind farm generation, even large hydro these days—we can do it,” said Louis Guilbault, who works in regulatory affairs at Hydro-Québec. For Quebec-produced wind energy, for example, “I can trade those to whoever’s willing to buy it,” he said.

But, despite having the ability, he also has the choice not to attach a detailed code—which Hydro doesn’t do for most of its hydropower—and to have it counted instead under the generic term of “system mix.”

Once that hydropower hits the New England market, the administrators there have their own way of packaging it. The market perhaps “tries to determine emissions, GHG content,” Guilbault said. “They have their own rules; they do their own calculations.”

This is the crux of what bothers people like Donovan and Bodell. Hydro-Québec is fully meeting its contractual obligations, since it’s not required to attach a code to every export. But the critics wish it would, whether by future obligation or on its own volition.

Quebec wants it both ways, Donovan argued; it wants the benefits of selling low-emission energy without joining the New England system of checks and balances.

“We could just buy undifferentiated power and be done with it, but we want carbon-free power,” Donovan said. “We’re buying it because of its carbon content—that’s the reason.”

Still, the requirements are slowly increasing. Under Hydro-Québec’s future contract with Massachusetts (which still has several regulatory steps to go through before it’s approved) it’s asked to sell the power’s attributes, not just the power itself. That means that, at least on paper, Massachusetts wants to be able to trace the energy back to a single location in Quebec.

“It’s part of the contract we just signed with them,” said Guilbault. “We’re going to deliver those attributes. I’m going to select a specific hydro facility, put the number in...and transfer that to the buyers.”

Hydro-Québec says it’s voluntarily increasing its accounting in other ways. “Even though this is not strictly required,” said spokeswoman Lynn St. Laurent, Hydro is tracking its entire output with a continent-wide registry, the North American Renewables Registry.

That registry is separate from New England’s, so as far as Bodell is concerned, the measure doesn’t really help. But she and others also expect the entire tracking system to grow and mature, perhaps integrating into one. If it had been created today, in fact, rather than in the 1990s, maybe it would use blockchain technology rather than a varied set of administrators, she said.

Counting emissions through tracking still has a long way to go, as well, said Donovan, and it will increasingly matter in Canada's race to net-zero as standards tighten. For example, natural gas is assigned an emissions number that’s meant to reflect the emissions when it’s consumed. But “we do not take into account what the upstream carbon emissions are through the pipeline leakage, methane releases during fracking, any of that,” she said.

Now that the search for exactitude has begun, Hydro-Québec won’t be exempt, whether or not Quebeckers share that curiosity. “We don’t know what Hydro-Québec is doing on the other side of the border,” said Donovan.

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

Key Points

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

Smart Street Lighting NY delivers Syracuse-wide LED retrofits with smart controls, Wi-Fi, and sensors, saving $3.3 million annually and cutting nearly 8,500 tons of greenhouse gases, improving energy efficiency, safety, and maintenance.

Key Points

A NYPA-backed program replacing streetlights with LED and controls to cut costs and emissions across New York by 2025.

✅ Syracuse replaced 17,500 fixtures with LED and smart controls.

✅ Saves $3.3M yearly; cuts 8,500 tons CO2e; improves safety.

✅ NYPA financing and maintenance support enable Smart City sensors.

Governor Andrew M. Cuomo today announced the completed installation of energy-efficient LED streetlights throughout the City of Syracuse as part of the Governor's Smart Street Lighting NY program. Syracuse, through a partnership with the New York Power Authority, replaced all of its streetlights with the most comprehensive set of innovative Smart City technologies in the state, saving the city $3.3 million annually and reducing greenhouse gas emissions by nearly 8,500 tons a year--the equivalent of taking more than 1,660 cars off the road. New York has now replaced more than 100,000 of its streetlights with LED fixtures, reflecting broader state renewable ambitions across the country, a significant milestone in the Governor's goal to replace at least 500,000 streetlights with LED technology by 2025 under Smart Street Lighting NY.

Today's announcement directly supports the goals of the Climate Leadership and Community Protection Act, the most aggressive climate change law in the nation, through the increased use of energy efficiency, exemplified by Seattle City Light's program that helps customers reduce bills, to annually reduce electricity demand by three percent--equivalent to 1.8 million New York households--by 2025.

"As we move further into the 21st century, it's critical we make the investments necessary for building smarter, more sustainable communities and that's exactly what we are doing in Syracuse," Governor Cuomo said. "Not only is the Smart Street Lighting NY program reducing the city's carbon footprint, but millions of taxpayer dollars will be saved thanks to a reduction in utility costs. Climate change is not going away and it is these types of smart, forward-thinking programs which will help communities build towards the future."

The more than $16 million cutting-edge initiative, implemented by NYPA, includes the replacement of approximately 17,500 streetlights throughout the city with SMART, LED fixtures, improving lighting quality and neighborhood safety while saving energy and maintenance costs. The city's streetlights are now outfitted with SMART controls that provide programmed dimming ability, energy metering, fault monitoring, and additional tools for emergency services through on-demand lighting levels.

"The completion of the replacement of LED streetlights in Syracuse is part of our overall efforts to upgrade more than 100,000 streetlights across the state," Lieutenant Governor Kathy Hochul said. "The new lights will save the city $3.3 million annually, helping to reduce cost for energy and maintenance and reducing greenhouse gas emissions. These new light fixtures will also help to improve safety and provide additional tools for emergency services. The conversion of streetlights statewide to high-tech LED fixtures will help local governments and taxpayers save money, while increasing efficiency and safety as we work to build back better and stronger for the future."

NYPA provided Syracuse with a $500,000 Smart Cities grant for the project. The city utilized the additional funding to support special features on the streetlights that demonstrate the latest in Smart City technologies, focused on digital connectivity, environmental monitoring and public safety. These features are expected to be fully implemented in early 2021.

Connectivity: The city is planning to deploy exterior Wi-Fi at community centers and public spaces, including in neighborhoods in need of expanded digital network services.

Environmental Monitoring: Ice and snow detection systems that assist city officials in pinpointing streets covered in ice or snow and require attention to prevent accidents and improve safety. The sensors provide data that can tell the city where salt trucks and plows are most needed instead of directing trucks to drive pre-determined routes. Flood reporting and monitoring systems will also be installed.

Public Safety and Property Protection: Illegal dumping and vandalism detection sensors will be installed at strategic locations to help mitigate these disturbances. Vacant house monitoring will also be deployed by the city. The system can monitor for potential fires, detect motion and provide temperature and humidity readings of vacant homes. Trash bin sensors will be installed at various locations throughout the city that will detect when a trash bin is full and alert local officials for pick-up.

NYPA President and CEO Gil C. Quiniones said, "Syracuse is truly a pioneer in its exploration of using SMART technologies to improve public services and the Power Authority was thrilled to partner with the city on this innovative initiative. Helping our customers bring their streetlights into the future further advances NYPA's reputation as a first-mover in the energy-sector."

New York State Public Service Commission Chair John B. Rhodes said, "Governor Cuomo signed legislation making it easier for municipalities to purchase and upgrade their street lighting systems. With smart projects like these, cities such as Syracuse can install state-of-the-art, energy efficient lights and take control over their energy use, lower costs to taxpayers and protect the environment."

Mayor Ben Walsh said, "Governor Cuomo and the New York Power Authority have helped power Syracuse to the front of the pack of cities in the U.S., leveraging SMART LED lighting to save money and make life better for our residents. Because of our progress, even in the midst of a global pandemic, the Syracuse Surge, our strategy for inclusive growth in the New Economy, continues to move forward. Syracuse and all of New York State are well positioned to lead the nation and the world because of NYPA's support and the Governor's leadership."

To date, NYPA has installed more than 50,000 LED streetlights statewide, with more than 115,000 lighting replacements currently implemented. Some of the cities and towns that have already converted to LED lights, in collaboration with NYPA, include Albany, Rochester, and White Plains. In addition, the Public Service Commission, whose ongoing retail energy markets review informs consumer protections, in conjunction with investor-owned utilities around the state, has facilitated the installation of more than 50,000 additional LED lights.

The NYPA Board of Trustees, in support of the Smart Street Lighting NY program, authorized at its September meeting the expenditure of $150 million over the next five years to secure the services of Candela Systems in Hawthorne, D&M Contracting in Elmsford and E-J Electric T&D in Wallingford, Connecticut, while in other regions, city officials take a clean energy message to Georgia Power and the PSC to spur utility action. All three firms will work on behalf of NYPA to continue to implement LED lighting replacements throughout New York State to meet the Governor's goal of 500,000 LED streetlights installed by 2025.

Smart Street Lighting NY: Energy Efficient and Economically Advantageous

NYPA is working with cities, towns, villages and counties throughout New York to fully manage and implement a customer's transition to LED streetlight technology. NYPA provides upfront financing for the project, and during emergencies, New York's utility disconnection moratorium helps protect customers while payments to NYPA are made in the years following from the cost-savings created by the reduced energy use of the LED streetlights, which are 50 to 65 percent more efficient than alternative street lighting options.

Through this statewide street lighting program, NYPA's government customers are provided a wide-array of lighting options to help meet their individual needs, including specifications on the lights to incorporate SMART technology, which can be used for dozens of other functions, such as cameras and other safety features, weather sensors, Wi-Fi and energy meters.

To further advance the Governor's effort to replace existing New York street lighting, in 2019, NYPA launched a new maintenance service to provide routine and on-call maintenance services for LED street lighting fixtures installed by NYPA throughout the state, and during the COVID-19 response, New York and New Jersey suspended utility shut-offs to protect customers and maintain essential services. The new service is available to municipalities that have engaged NYPA to implement a LED street lighting conversion and have elected to install an asset management controls system on their street lighting system, reducing the number of failures and repairs needed after installation is complete.

New York State's Nation-Leading Climate Plan

Governor Cuomo's nation-leading climate plan is the most aggressive climate and clean energy initiative in the nation, calling for an orderly and just transition to clean energy that creates jobs and continues fostering a green economy as New York State builds back better as it recovers from the COVID-19 pandemic. Enshrined into law through the CLCPA, New York is on a path to reach its mandated goals of economy wide carbon neutrality and achieving a zero-carbon emissions electricity sector by 2040, similar to Ontario's clean electricity regulations that advance decarbonization, faster than any other state. It builds on New York's unprecedented ramp-up of clean energy including a $3.9 billion investment in 67 large-scale renewable projects across the state, the creation of more than 150,000 jobs in New York's clean energy sector, a commitment to develop over 9,000 megawatts of offshore wind by 2035, and 1,800 percent growth in the distributed solar sector since 2011. New York's Climate Action Council is working on a scoping plan to build on this progress and reduce greenhouse gas emissions by 85 percent from 1990 levels by 2050, while ensuring that at least 40 percent of the benefits of clean energy investments benefit disadvantaged communities, and advancing progress towards the state's 2025 energy efficiency target of reducing on-site energy consumption by 185 TBtus.

Surkhan-Pul-e-Khumri Power Line links Uzbekistan and Afghanistan via a 260-kilometer transmission line, boosting electricity exports, grid reliability, and regional trade; ADB-backed financing could open Pakistan's energy market with 24 million kWh daily.

Key Points

A 260-km line to expand Uzbekistan power exports to Afghanistan, ADB-funded, with possible future links to Pakistan.

✅ 260 km Surkhan-Pul-e-Khumri transmission link

✅ +70% electricity exports; up to 24M kWh daily

✅ ADB $70M co-financing; $32M from Uzbekistan

Senior officials with Uzbekistan’s state-run power company have said work has begun on building power cables to Afghanistan that will enable them to increase exports by 70 per cent, echoing regional trends like Ukraine resuming electricity exports after grid repairs.

Uzbekenergo chief executive Ulugbek Mustafayev said in a press conference on March 24 that construction of the Afghan section of the 260-kilometer Surkhan-Pul-e-Khumri line will start in June.

The Asian Development Bank has pledged $70 million toward the final expected $150 million bill of the project. Another $32 million will come from Uzbekistan.

Mustafayev said the transmission line would give Uzbekistan the option of exporting up to 24 million kilowatt hours to Afghanistan daily, similar to Ukraine's electricity export resumption amid shifting regional demand.

“We could potentially even reach Pakistan’s energy market,” he said, noting broader regional ambitions like Iran's bid to be a power hub linking regional grids.

This project was given fresh impetus by Afghan President Ashraf Ghani’s visit to Tashkent in December, mirroring cross-border energy cooperation such as Iran-Iraq energy talks in the region. His Uzbek counterpart, Shavkat Mirziyoyev, had announced at the time that work was set to begin imminently on the line, which will run from the village of Surkhan in Uzbekistan’s Surkhandarya region to Pul-e-Khumri, a town in Afghanistan just south of Kunduz.

In January, Mirziyoyev issued a decree ordering that the rate for electricity deliveries to Afghanistan be dropped from $0.076 to $0.05 per kilowatt.

Mustafayev said up to 6 billion kilowatt hours of electricity could eventually be sent through the power lines. More than 60 billion kilowatt hours of electricity was produced in Uzbekistan in 2017.

According to Tulabai Kurbonov, an Uzbek journalist specializing in energy issues, the power line will enable the electrification of the the Hairatan-Mazar-i-Sharif railroad joining the two countries. Trains currently run on diesel. Switching over to electricity will help reduce the cost of transporting cargo.

There is some unhappiness, however, over the fact that Uzbekistan plans to sell power to Afghanistan when it suffers from significant shortages domestically and wider Central Asia electricity shortages persist.

"In the villages of the Ferghana Valley, especially in winter, people are suffering from a shortage of electricity,” said Munavvar Ibragimova, a reporter based in the Ferghana Valley. “You should not be selling electricity abroad before you can provide for your own population. What we clearly see here is the favoring of the state’s interests over those of the people.”
