Nuclear plant testing gets OK

Siwash Creek Hydroelectric Project faces downsizing under a BC Hydro power purchase agreement, with run-of-river generation, high grid interconnection costs, First Nations partnership, and surplus electricity from Site C reshaping clean energy procurement.

Key Points

A downsized run-of-river plant in BC, co-owned by Kanaka Bar and Green Valley, selling power via a BC Hydro PPA.

✅ Approved at 500 kW under a BC Hydro clean-energy program

✅ Grid interconnection initially quoted at $2.1M

✅ Joint venture: Kanaka Bar and Green Valley Power

A small run-of-river hydroelectric project recently selected by B.C. Hydro for a power purchase agreement may no longer be financially viable.

The Siwash Creek project was originally conceived as a two-megawatt power plant by the original proponent Chad Peterson, who holds a 50-per-cent stake through Green Valley Power, with the Kanaka Bar Indian Band holding the other half.

The partners were asked by B.C. Hydro to trim the capacity back to one megawatt, but by the time the Crown corporation announced its approval, it agreed to only half that — 500 kilowatts — under its Standing Order clean-energy program.

“Hydro wanted to charge us $2.1 million to connect to the grid, but then they said they could reduce it if we took a little trim on the project,” said Kanaka Bar Chief Patrick Michell.

The revenue stream for the band and Green Valley Power has been halved to about $250,000 a year. The original cost of running the $3.7-million plant, including financing, was projected to be $273,000 a year, according to the Kanaka Bar economic development plan.

“By our initial forecast, we will have to subsidize the loan for 20 years,” said Michell. “It doesn’t make any sense.”

The Kanaka Band has already invested $450,000 in feasibility, hydrology and engineering studies, with a similar investment from Green Valley.

B.C. Hydro announced it would pursue five purchase agreements last March with five First Nations projects — including Siwash Creek — including hydro, solar and wind energy projects, as two new generating stations were being commissioned at the time. A purchase agreement allows proponents to sell electricity to B.C. Hydro at a set price.

However, at least ten other “shovel-ready” clean energy projects may be doomed while B.C. Hydro completes a review of its own operations and its place in the energy sector, where legal outcomes like the Squamish power project ruling add uncertainty, including B.C.’s future power needs.

With the 1,100-megawatt Site C Dam planned for completion in 2024, and LNG demand cited to justify it, B.C. Hydro now projects it will have a surplus of electricity until the early 2030s.

Even if British Columbians put 300,000 electric vehicles on the road over the next 12 years, amid BC Hydro’s first call for power, they will require only 300 megawatts of new capacity, the company said.

A long-term surplus could effectively halt all small-scale clean energy development, according to Clean Energy B.C., even as Hydro One’s U.S. coal plant remains online in the region.

“(B.C. Hydro) dropped their offer down to 500 kilowatts right around the time they announced their review,” said Michell. “So we filled out the paperwork at 500 kilowatts and (B.C. Hydro) got to make its announcement of five projects.”

In the new few weeks, Kanaka and Green Valley will discuss whether they can move forward with a new financial model or shelve the project, he said.

B.C. Hydro declined to comment on the rationale for downsizing Siwash Creek’s power purchase agreement.

The Kanaka Bar Band successfully operates a 49.9-megawatt run-of-river plant on Kwoiek Creek with partners Innergex Renewable Energy.

Western Washington Bomb Cyclone unleashed gale-force winds, torrential rain, and coastal flooding, causing massive power outages from Seattle to Tacoma; storm surge, downed trees, and blocked roads hindered emergency response and infrastructure repairs.

Key Points

A rapidly deepening storm with severe winds, rain, flooding, and major power outages across Western Washington.

✅ Rapid barometric pressure drop intensified the system

✅ Gale-force winds downed trees and power lines

✅ Coastal flooding and storm surge disrupted transport

A powerful "bomb cyclone" recently hit Western Washington, causing widespread destruction across the region. The intense storm left more than half a million residents without power, similar to B.C. bomb cyclone outages seen to the north, with outages affecting communities from Seattle to Olympia. This weather phenomenon, marked by a rapid drop in atmospheric pressure, unleashed severe wind gusts, heavy rain, and flooding, causing significant disruption to daily life.

The bomb cyclone, which is a rapidly intensifying storm, typically features a sharp drop in barometric pressure over a short period of time. This creates extreme weather conditions, including gale-force winds, torrential rain, and coastal flooding, as seen during California storm impacts earlier in the season. In Western Washington, the storm struck just as the region was beginning to prepare for the winter season, catching many off guard with its strength and unpredictability.

The storm's impact was immediately felt as high winds downed trees, power lines, and other infrastructure. By the time the worst of the storm had passed, utility companies had reported widespread power outages, with more than 500,000 customers losing electricity. The outages were particularly severe in areas like Seattle, Tacoma, and the surrounding communities. Crews worked tirelessly in difficult conditions to restore power, but many residents faced extended outages, underscoring US grid climate vulnerabilities that complicate recovery efforts, with some lasting for days due to the scope of the damage.

The power outages were accompanied by heavy rainfall, leading to localized flooding. Roads were inundated, making it difficult for first responders and repair crews to reach affected areas. Emergency services were stretched thin as they dealt with downed trees, blocked roads, and flooded neighborhoods. In some areas, floodwaters reached homes, forcing people to evacuate. In addition, several schools were closed, and public transportation services were temporarily halted, leaving commuters stranded and businesses unable to operate.

As the storm moved inland, its effects continued to be felt. Western Washington’s coastal regions were hammered by high waves and storm surges, further exacerbating the damage. The combination of wind and rain also led to hazardous driving conditions, prompting authorities to advise people to stay off the roads unless absolutely necessary.

While power companies worked around the clock to restore electricity, informed by grid resilience strategies that could help utilities prepare for future events, challenges persisted. Fallen trees and debris blocked access to repair sites, and the sheer number of outages made it difficult for crews to restore power quickly. Some customers were left in the dark for days, forced to rely on generators, candles, and other makeshift solutions. The storm's intensity left a trail of destruction, requiring significant resources to address the damages and rebuild critical infrastructure.

In addition to the immediate impacts on power and transportation, the bomb cyclone raised important concerns about climate change and the increasing frequency of extreme weather events. Experts note that storms like these are becoming more common, with rapid intensification leading to more severe consequences and compounding pressures such as extreme-heat electricity costs for households. As the planet warms, scientists predict that such weather systems will continue to grow in strength, posing greater challenges to cities and regions that are not always prepared for such extreme events.

In the aftermath of the storm, local governments and utility companies faced the daunting task of not only restoring services but also assessing the broader impact of the storm on communities. Many areas, especially those hit hardest by flooding and power outages, will require substantial recovery efforts. The devastation of the bomb cyclone highlighted the vulnerability of infrastructure in the face of rapidly changing weather patterns and water availability, as seen in BC Hydro drought adaptations nearby, and reinforced the need for greater resilience in the face of future storms.

The storm's impact on the Pacific Northwest is a reminder of the power of nature and the importance of preparedness. As Western Washington recovers, there is a renewed focus on strengthening infrastructure, including expanded renewable electricity to diversify supply, improving emergency response systems, and ensuring that communities are better equipped to handle the challenges posed by increasingly severe weather events. For now, residents remain hopeful that the worst is behind them and are working together to rebuild and prepare for whatever future storms may bring.

The bomb cyclone has left an indelible mark on Western Washington, but it also serves as a call to action for better preparedness, more robust infrastructure, and a greater focus on combating climate change to mitigate the impact of such extreme weather in the future.

UK Hydrogen Storage Caverns enable long-duration, low-carbon electricity balancing, storing surplus wind and solar power as green hydrogen in salt formations to enhance grid reliability, energy security, and net zero resilience by 2035 and 2050.

Key Points

They are salt caverns storing green hydrogen to balance wind and solar, stabilizing a low-carbon UK grid.

✅ Stores surplus wind and solar as green hydrogen in salt caverns

✅ Enables long-duration, low-carbon grid balancing and security

✅ Complements wind and solar; reduces dependence on flexible CCS

The U.K. government must kick-start the construction of large-scale hydrogen storage facilities if it is to meet its pledge that all electricity will come from low-carbon electricity sources by 2035 and reach legally binding net zero targets by 2050, according to a report by the Royal Society.

The report, "Large-scale electricity storage," published Sep. 8, examines a wide variety of ways to store surplus wind and solar generated electricity—including green hydrogen, advanced compressed air energy storage (ACAES), ammonia, and heat—which will be needed when Great Britain's electricity generation is dominated by volatile wind and solar power.

It concludes that large scale electricity storage is essential to mitigate variations in wind and sunshine, particularly long-term variations in the wind, and to keep the nation's lights on. Storing most of the surplus as hydrogen, in salt caverns, would be the cheapest way of doing this.

The report, based on 37 years of weather data, finds that in 2050 up to 100 Terawatt-hours (TWh) of storage will be needed, which would have to be capable of meeting around a quarter of the U.K.'s current annual electricity demand. This would be equivalent to more than 5,000 Dinorwig pumped hydroelectric dams. Storage on this scale, which would require up to 90 clusters of 10 caverns, is not possible with batteries or pumped hydro.

Storage requirements on this scale are not currently foreseen by the government, and the U.K.'s energy transition faces supply delays. Work on constructing these caverns should begin immediately if the government is to have any chance of meeting its net zero targets, the report states.

Sir Chris Llewellyn Smith FRS, lead author of the report, said, "The need for long-term storage has been seriously underestimated. Demand for electricity is expected to double by 2050 with the electrification of heat, transport, and industrial processing, as well as increases in the use of air conditioning, economic growth, and changes in population.

"It will mainly be met by wind and solar generation. They are the cheapest forms of low-carbon electricity generation, but are volatile—wind varies on a decadal timescale, so will have to be complemented by large scale supply from energy storage or other sources."

The only other large-scale low-carbon sources are nuclear power, gas with carbon capture and storage (CCS), and bioenergy without or with CCS (BECCS). While nuclear and gas with CCS are expected to play a role, they are expensive, especially if operated flexibly.

Sir Peter Bruce, vice president of the Royal Society, said, "Ensuring our future electricity supply remains reliable and resilient will be crucial for our future prosperity and well-being. An electricity system with significant wind and solar generation is likely to offer the lowest cost electricity but it is essential to have large-scale energy stores that can be accessed quickly to ensure Great Britain's energy security and sovereignty."

Combining hydrogen with ACAES, or other forms of storage that are more efficient than hydrogen, could lower the average cost of electricity overall, and would lower the required level of wind power and solar supply.

There are currently three hydrogen storage caverns in the U.K., which have been in use since 1972, and the British Geological Survey has identified the geology for ample storage capacity in Cheshire, Wessex and East Yorkshire. Appropriate, novel business models and market structures will be needed to encourage construction of the large number of additional caverns that will be needed, the report says.

Sir Chris observes that, although nuclear, hydro and other sources are likely to play a role, Britain could in principle be powered solely by wind power and solar, supported by hydrogen, and some small-scale storage provided, for example, by batteries, that can respond rapidly and to stabilize the grid. While the cost of electricity would be higher than in the last decade, we anticipate it would be much lower than in 2022, he adds.

Alberta Coal Community Transition Fund backs renewables, natural gas, and economic diversification, offering grants, workforce retraining, and community development to municipalities and First Nations as Alberta phases out coal-fired power by 2030.

Key Points

A provincial grant helping coal-impacted communities diversify, retrain workers, and transition to renewables by 2030.

✅ Grants for municipalities and First Nations

✅ Supports diversification and job retraining

✅ Focus on renewables, natural gas, and new sectors

The Coal Community Transition Fund is open to municipalities and First Nations affected as Alberta phases out coal-fired electricity by 2030 under the federal coal plan to focus on renewables and natural gas.

Economic Development Minister Deron Bilous says the government wants to ensure these communities thrive through the transition, aligning with views that fossil-fuel workers support the energy transition across the economy.

“Residents in our communities have concerns about the transition away from coal, even as discussions about phasing out fossil fuels in B.C. unfold nationally,” Rod Shaigec, mayor of Parkland County, said.

“They also have ideas on how we can mitigate the impacts on workers and diversify our economy, including clean energy partnerships to create new employment opportunities for affected workers. We are working to address those concerns and support their ideas. This funding means we can make those ideas a reality in various economic sectors of opportunity.”

The coal-mining town of Hanna, northeast of Calgary, has already received $450,000 through the program to work on economic diversification, exploring options like bridging the Alberta-B.C. electricity gap that could support new industries.

The application deadline for the coal transition fund is the end of November.

A provincial advisory panel is also expected to report back this fall on ways to create new jobs and retrain workers during the coal phase-out.

5G Energy Costs highlight base station power consumption, carrier electricity bills, and carbon emissions in China, while advances in energy efficiency, sleep modes, and cooling systems aim to optimize low-latency networks and reduce operational expenses.

Key Points

5G energy costs rise with power-hungry base stations, yet per-bit efficiency and sleep modes help cut bills.

✅ 5G base stations use ~4x 4G electricity

✅ Per-bit 5G energy efficiency is ~4x better than 4G

✅ Sleep modes and advanced cooling reduce OPEX and emissions

As 5G developers look desperately for a "killer app" to prove the usefulness of the superfast wireless technology, mobile carriers in China are complaining about the high energy cost of 5G signal towers.

And the situation is, according to experts, more complicated than many have thought.

The costly 5G

5G technology can be 10 or more times faster than 4G and significantly more responsive to users' input, but the speed comes at a cost.

A 5G base station consumes "four times more electricity" than its 4G counterpart, said Ding Haiyu, head of wireless and terminals at the China Mobile Research Institute, during a symposium on 5G and carbon neutrality in Beijing, a key focus for countries pursuing a net-zero grid by 2050 worldwide.

But concerning each bit of data transmitted, 5G is four times more energy-efficient than 4G, according to Ding.

This means that mobile carriers should fully occupy their 5G network for as long time as possible, but that can be hard at this moment, as many people are still holding 4G smartphones.

"When the 5G stations are running without people using them, they are really electricity guzzlers," said Zhu Qingfeng, head of power supply design at China Information Technology Designing and Consulting Institute Co., Ltd., who represents China Unicom at the symposium. "Each of the three telecom carrier giants are emitting about ten million tonnes of carbon in the air."

"We have to shut down some 5G base stations at night to reduce emission," he added.

Some utilities are testing fuel cell solutions to keep backup batteries charged much longer, supporting network resilience at lower emissions.

A representative from China Telecom said electricity bills of the nationwide carrier reached a new high of 100 billion yuan (about $15 billion) a year, mirroring the power challenges for utilities as data center demand booms elsewhere.

Getting better

While admitting the excessive cost of 5G, experts at the symposium also agreed that the situation is improving, even as climate pressures on the grid continue to mount.

Ding listed a series of recent technologies that is helping reduce the energy use of 5G, including chips of better process, automatic sleeping and wake-up of base stations and liquid nitrogen-based cooling system, and superconducting cables as part of ongoing upgrades.

"We are aiming at halving the 5G electricity cost to only two times of 4G in two years," Ding said.

Experts also discussed the possibility of making use of 5G's low latency features to help monitoring the electricity grid, thus making the digital grid smarter and more cost effective.

G's energy cost is seen as a hot topic for the incoming World 5G Convention in Beijing in early August, alongside smart grid transformation themes. Stay tuned to CGTN Digital as we bring you the latest news about the convention and 5G technology.

Coinmint Plattsburgh Dispute spotlights cryptocurrency mining, hydropower electricity rates, a $1M security deposit, Public Service Commission rulings, municipal utility policies, and seasonal migration to Massena data centers as Bitcoin price volatility pressures operations.

Key Points

Legal and energy-cost dispute over crypto mining, a $1,019,503 deposit, and operations in Plattsburgh and Massena.

✅ PSC allows higher rates and requires large security deposits.

✅ Winter electricity spikes drove a $1M deposit calculation.

✅ Coinmint shifted capacity to Massena data centers.

A few years ago, there was a lot of buzz about the North Country becoming the next Silicon Valley of cryptocurrency, even as Maine debated a 145-mile line that could reshape regional power flows. One of the companies to flock here was Coinmint. The cryptomining company set up shop in Plattsburgh in 2017 and declared its intentions to be a good citizen.

Today, Coinmint is fighting a legal battle to avoid paying the city’s electric utility more than $1 million owed for a security deposit. In addition to that dispute, a local property manager says the firm was evicted from one of its Plattsburgh locations.

Companies like Coinmint chose to come to the North Country because of the relatively low electricity prices here, thanks in large part to the hydropower dam on the St. Lawrence River in Massena, and regionally, projects such as the disputed electricity corridor have drawn attention to transmission costs and access. Coinmint operates its North Country Data Center facilities in Plattsburgh and Massena. In both locations, racks of computer servers perform complex calculations to generate cryptocurrency, such as bitcoin.

When cryptomining began to take off in Plattsburgh, the cost of one bitcoin was skyrocketing. That brought hype around the possibility of big business and job creation in the North Country. But cryptomininers like Coinmint were using massive amounts of energy in the winter of 2017-2018, and that season, electric bills of everyday Plattsburgh residents spiked.

Many cryptomining firms operate in a state of flux, beholden to the price of Bitcoin and other cryptocurrencies, even as the end to the 'war on coal' declaration did little to change utilities' choices. When the price of one bitcoin hit $20,000 in 2017, it fell by 30% just days later. That’s one reason why the price of electricity is so critical for companies like Coinmint to turn a profit. 

Plattsburgh puts the brakes on “cryptocurrency mining”
In early 2018, Plattsburgh passed a moratorium on cryptocurrency mining operations, after residents complained of higher-than-usual electric bills.

“Your electric bill’s $100, then it’s at $130. Why? It’s because these guys that are mining the bitcoins are riding into town, taking advantage of a situation,” said resident Andrew Golt during a 2018 public hearing.

Coinmint aimed to assuage the worries of residents and other businesses. “At the end of the day we want to be a good citizen in whatever communities we’re in,” Coinmint spokesman Kyle Carlton told NCPR at that 2018 meeting.

“We’re open to working with those communities to figure out whatever solutions are going to work.”

The ban was lifted in Feb. 2019. However, since it didn’t apply to companies that were already mining cryptocurrency in Plattsburgh, Coinmint has operated in the city all along.

Coinmint challenges attempt to protect ratepayers
New rules passed by the New York Public Service Commission in March 2018 allow municipal power authorities including Plattsburgh’s to charge big energy users such as Coinmint higher electricity rates, amid customer backlash in other utility deals. The new rules also require them to put down a security deposit to ensure their bills get paid.

But Coinmint disputes that deposit charge. The company has been embroiled in a legal fight for nearly a year against Plattsburgh Municipal Lighting Department (PMLD) in an attempt to avoid paying the electric utility’s security deposit bill of $1,019,503. That bill is based on an estimate of what would cover two months of electricity use if a company were to leave town without paying its electric bills.

Coinmint would not discuss the dispute on the record with NCPR. Legal documents show the firm argues the deposit charge is inflated, based on a flawed calculation resulting in a charge hundreds of thousands of dollars higher than what it should be.

“Essentially they’re arguing that they should only have to put up some average of their monthly bills without accounting for the fact that winter bills are significantly higher than the average,” said Ken Podolny, an attorney representing the Plattsburgh utility.

The company took legal action in February 2019 against PMLD in the hopes New York’s energy regulator, the Public Service Commission, would agree with Coinmint that the deposit charge was too high. An informal commission hearing officer disagreed, and ruled in October the charge was calculated correctly.

Coinmint appealed the ruling in November and a hearing on the appeal could come as soon as February.

Less than a week after Coinmint lost its initial challenge of the deposit charge, the company made a splashy announcement trumpeting its plans to “migrate its Plattsburgh, New York infrastructure to its Massena, New York location for the 2019-2020 winter season.”

The announcement made no mention of the appeal or the recent ruling against Coinmint. The company attributed its new plan to “exceptionally-high” electricity rates in Plattsburgh, as hydropower transmission projects elsewhere in New England faced their own controversies. 

"We recognize some in the Plattsburgh community have blamed our operation for pushing rates higher for everyone so, while we disagree with that assessment, we hope this seasonal migration will have a positive impact on rates for all our neighbors,” said Coinmint cofounder Prieur Leary in the press statement.

“In the event that doesn't happen, we trust the community will look for the real answers for these high costs." Prieur Leary has since been removed from the corporate team page on the company’s website.

The company still operates in Plattsburgh at one of its locations in the city. As for staff, while at least two Coinmint employees have moved from Plattsburgh to Massena, where the company operates a data center inside a former Alcoa aluminum plant, it is unclear how many people in total have made the move.

Coinmint left its second Plattsburgh location in 2019. The company would not discuss that move on the record, yet the circumstances of the departure are murky.

The local property manager of the industrial park site told NCPR, “I have no comment on our evicted tenant Coinmint.” The property owner, California’s Karex Property Management Services, also would not comment regarding the situation, noting that “all staff have been told to not discuss anything regarding our past tenant Coinmint.”

Today, Bitcoin and other cryptocurrencies are worth a fraction of what they were back in 2017 when Coinmint came to the North Country, and now, amid a debate over Bitcoin's electricity use shaping market sentiment, the future of the entire industry here remains uncertain.
