State environmental officials have already cleared a controversial wood-to-energy plant in Plainfield, but activists say that's not good enough.

They say the plant — the recent site of an FBI investigation into toxic dumping by alleged eco-terrorists — will harm the environment. They've asked the state Department of Environmental Protection to reconsider issuing permits for the project. If the DEP refuses, environmentalists say they'll take their battle to court.

Opponents say discarded wood and construction debris burned at the plant to make electricity would send toxins into the air and that a water-based cooling system planned for the plant would deplete the Quinebaug River.

"Years ago, the big joke was, 'What color is the river today?'" said Bob Noiseux, a member of the Friends of the Quinebaug River, about the way the river looked when Plainfield's textile mills used the river as a dumping ground.

"Now that the river is finally on the mend, this project will be a step backward for the river."

But Daniel Donovan, one of the developers of the proposed $160 million plant, said the project has already been through three years of vigorous vetting by the DEP. The activists' protests, threats of dumped toxins and a recent financial setback aren't stopping him from moving ahead with a project he says will help stop the state's dependence on such fossil fuels as oil, coal and natural gas.

"Hopefully, when everyone starts to move away from this misinformation about the project, people will start to understand what a great project this is not just for Connecticut but for the United States," Donovan said.

Last month, state DEP Commissioner Gina McCarthy approved permits for the project, including permits to construct and operate a solid waste facility, discharge water and withdraw water from the Quinebaug River. In her decision, McCarthy added a requirement that the plant retain the services of an independent "fuel quality management monitor" to make sure the plant stays in compliance with permit requirements.

An agency hearing officer, who reviewed a Friends of the Quinebaug River's petition against the plan, concluded in a Dec. 22, 2008, report that the project would "meet the applicable legal and regulatory standards."

The hearing officer said opponents of the plan failed to prove that the project by Plainfield Renewable Energy would cause "unreasonable pollution, impairment, or destruction of the air, water, or other natural resources of the state."

The power plant, a joint venture between Florida-based Decker Energy International Inc. and NuPower LLC of Connecticut, is slated for a 29-acre site in Plainfield. A pump house and water pipeline are also planned for a nearby site in Canterbury.

Donovan said most of the land — about the length of two football fields — will be used to store wood debris that currently gets trucked to landfills in Ohio and Pennsylvania. The proposed 37.5-megawatt plant could power about 30,000 homes, he said.

A former Superfund cleanup site, the land has since been remediated, Donovan said. A hazardous chemical dumped there earlier this month — purportedly by an environmental group opposed to the project — has been removed.

Deputy Chief State's Attorney Paul E. Murray said local, state and FBI investigators are working jointly on the dump probe, examining a letter sent to Plainfield Renewable Energy's Norwalk office in which activists claiming to be affiliated with Earth First! Journal out of Tucson, Ariz., said the group would do "everything within its power to stop" the plant, including dumping toxins at the site.

Authorities won't say what was dumped there but sources close to the investigation said its hazardous effects were minor. In an e-mail statement, Earth First! Journal in Tucson said it has nothing to do with the threat.

Supporters of wood-to-energy plants say such plants reduce the uses of fossil fuels, lower emissions and produce energy from a sustainable source. During the process, wood chips are loaded into a boiler and heated to make a gas. That gas is then ignited to create steam, which turns a turbine to generate electricity.

The Connecticut Clean Energy Fund, which promotes the development of clean energy throughout the state, loaned $500,000 to Plainfield Renewable Energy in the project's early stages, but when the firm sought an additional $2.5 million from the fund last month, the board declined to act on the request.

"It would have been the preferred option, but we're moving forward and we have other solutions," Donovan said about the lost funds.

Canadian Solar and Tesla contribute to resilient electricity system for Puerto Rico school

SunCrate Solar Microgrid delivers resilient, plug-and-play renewable power to Puerto Rico schools, combining Canadian Solar PV, Tesla Powerwall battery storage, and Black & Veatch engineering to ensure off-grid continuity during outages and disasters.

 

Key Points

A compact PV-and-battery system for resilient, diesel-free power and microgrid backup at schools and clinics.

✅ Plug-and-play, modular PV, inverter, and battery architecture

✅ Tesla Powerwall storage; Canadian Solar 325 W panels

✅ Scales via daisy-chain for higher loads and microgrids

 

Eleven months since their three-building school was first plunged into darkness by Hurricane Maria, 140 students in Puerto Rico’s picturesque Yabucoa district have reliable power. Resilient electricity service was provided Saturday to the SU Manuel Ortiz school through an innovative scalable, plug-and-play solar system pioneered by SunCrate Energy with Black & Veatch support. Known as a “SunCrate,” the unit is an effective mitigation measure to back up the traditional power supply from the grid. The SunCrate can also provide sustainable power in the face of ongoing system outages and future natural disasters without requiring diesel fuel.

The humanitarian effort to return sustainable electricity to the K-8 school, found along the island’s hard-hit southeastern coast, drew donated equipment and expertise from a collection of North American companies. Additional support for the Yabucoa project came from Tesla, Canadian Solar and Lloyd Electric, reflecting broader efforts to build a solar-powered grid in Puerto Rico after Hurricane Maria.

“We are grateful for this initiative, which will equip this school with the technology needed to become a resilient campus and not dependent on the status of the power grid. This means that if we are hit with future harmful weather events, the school will be able to open more quickly and continue providing services to students,” Puerto Rico Secretary of Education Julia Keleher said.

The SunCrate harnesses a scalable rapid-response design developed by Black & Veatch and manufactured by SunCrate Energy. Electricity will be generated by an array of 325-W CS6U-Poly modules from Canadian Solar. California-based Tesla contributed advanced battery energy storage through various Powerwall units capable of storing excess solar power and delivering it outside peak generation periods, with related experience from a virtual power plant in Texas informing deployment.  Lloyd Electric Co. of Wichita Falls, Texas, partnered to support delivery and installation of the SunCrate.

“As families in the region begin to prepare for the school year, this community is still impacted by the longest U.S. power outage in history,” said Dolf Ivener, a Midwestern entrepreneur who owns King of Trails Construction and SunCrate Energy, which is donating the SunCrate. “SunCrate, with its rapid deployment and use of renewable energy, should give this school peace of mind and hopefully returns a touch of long-overdue normalcy to students and their parents. When it comes to consistent power, SunCrate is on duty.”

The SunCrate is a portable renewable energy system conceived by Ivener and designed and tested by Black & Veatch. Its modular design uses solar PV panels, inverters and batteries to store and provide electric power in support of critical services such as police, fire, schools, clinics and other community level facilities.

A SunCrate can generate 23 to 156 kWh per day, and store 10 kWh to 135 kWh depending on configuration. A SunCrate’s power generation and storage capacity can be easily scaled through daisy-chained configurations to accommodate larger buildings and loads. Leveraging resources from Tesla, Canadian Solar, Lloyd Electric and Lord Electric, the unit in Yabucoa will provide an estimated 52 kWh of storable power without requiring use of costlier diesel-powered generators and cutting greenhouse gas emissions. Its capabilities allow the school to strengthen its function as a designated Community Emergency Response Center in the event of future natural disasters.

“Canadian Solar has a long history of using solar power to support humanitarian efforts aiding victims of social injustice and natural disasters, including previous donations to Puerto Rico after Hurricane Maria,” said Dr. Shawn Qu, Chairman and Chief Executive Officer of Canadian Solar. “We are pleased to make the difference for these schoolchildren in Yabucoa who have been without reliable power for too long.”

The SunCrate will also substantially lower the school’s ongoing electricity costs by providing a reliable source of renewable energy on site, as falling costs of solar batteries improve project economics overall.

“Through our experience providing engineering services in Puerto Rico for nearly 50 years, including dozens of specialized projects for local government and industrial clients, we see great potential for SunCrate as a source of resilient power for the Commonwealth’s remote schools and communities at large, underscoring the importance of electricity resilience across critical infrastructure,” said Charles Moseley, a Program Director in Black & Veatch’s water business. “We hope that the deployment of the SunCrate in Yabucoa sets a precedent for facility and municipal level migro-grid efforts on the island and beyond.”

SunCrate also has broad potential applications in conflict/post-conflict environments and in rural electrification efforts in the developing world, serving as a resilient source of electricity within hours of its arrival on site and could enable peer-to-peer energy within communities. Of particular benefit, the system’s flexibility cuts fuel costs to a fraction of a generator’s typical consumption when they are used around the clock with maintenance requirements.

Canadians Support Tariffs on Energy and Minerals in U.S. Trade Dispute

Canada Tariffs on U.S. Energy and Minerals signal retaliatory tariffs amid trade tensions, targeting energy exports and critical minerals, reflecting sovereignty concerns and shifting consumer behavior, reduced U.S. purchases, and demand for Canadian-made goods.

 

Key Points

They are proposed retaliatory tariffs on energy exports and critical minerals to counter U.S. trade pressures.

✅ 75% support tariffs; 70% back dollar-for-dollar retaliation

✅ Consumer shift: fewer U.S. purchases, more Canadian-made goods

✅ Concerns over sovereignty and U.S. trade tactics intensify

 

A recent survey has revealed that a significant majority of Canadians—approximately 75%—support the implementation of tariffs on energy exports and critical minerals in response to electricity exports at risk amid trade tensions with the United States. This finding underscores the nation's readiness to adopt assertive measures to protect its economic interests amid escalating trade disputes.​

Background on Trade Tensions

The trade relationship between Canada and the United States has experienced fluctuations in recent years, with both nations navigating complex issues related to tariffs and energy tariffs and trade tensions as well as trade agreements and economic policies. The introduction of tariffs has been a contentious strategy, often leading to reciprocal measures and impacting various sectors of the economy.​

Public Sentiment Towards Retaliatory Tariffs

The survey, conducted by Leger between February 14 and 17, 2025, sampled 1,500 Canadians and found that 70% favored implementing dollar-for-dollar retaliatory tariffs against the U.S. Notably, 45% of respondents were strongly in favor, while 25% were somewhat in favor. This strong support reflects widespread dissatisfaction with U.S. trade policies and growing support for Canadian energy projects among voters, alongside a collective sentiment favoring decisive action. ​

Concerns Over U.S. Economic Strategies

The survey also highlighted that 81% of Canadians are apprehensive about potential U.S. economic tactics aimed at drawing Canada into a closer political union. These concerns are fueled by statements from U.S. President Donald Trump, who has suggested annexation and employed tariffs that could spike NY energy prices to influence Canadian sovereignty. Such sentiments have heightened fears about the erosion of Canada's political autonomy under economic duress. ​

Impact on Consumer Behavior

In response to these trade tensions, including reports that Ford threatened to cut U.S. electricity exports, many Canadians have adjusted their purchasing habits. The survey indicated that 63% of respondents are buying fewer American products in stores, and 62% are reducing online purchases from U.S. retailers. Specific declines include a 52% reduction in Amazon purchases, a 50% drop in fast-food consumption from American chains, and a 43% decrease in spending at U.S.-based retail stores. Additionally, 30% of Canadians have canceled planned trips to the United States, while 68% have increased their purchases of Canadian-made products. These shifts demonstrate a tangible impact on consumer behavior driven by nationalistic sentiments and support for retaliatory measures. ​

Economic and Political Implications

The widespread support for retaliatory tariffs and the corresponding changes in consumer behavior have significant economic and political implications. Economically, while tariffs can serve as a tool for asserting national interests, they also risk triggering trade wars that can harm various sectors, including agriculture, manufacturing, and technology, with experts cautioning against cutting Quebec's energy exports in response. Politically, the situation presents a challenge for Canadian leadership to balance assertiveness in defending national interests with the necessity of maintaining a stable and mutually beneficial relationship with the U.S., Canada's largest trading partner.​

As Canada approaches its federal elections, trade policy is emerging as a pivotal issue. Voters are keenly interested in how political parties propose to navigate the complexities of international trade, particularly with the United States and how a potential U.S. administration's stance, such as Biden's approach to the energy sector could shape outcomes. The electorate's strong stance on retaliatory tariffs may influence party platforms and campaign strategies, emphasizing the need for clear and effective policies that address both the immediate concerns of trade disputes and the long-term goal of sustaining positive international relations.​

The survey results reflect a nation deeply engaged with its trade dynamics and protective of its sovereignty. While support for retaliatory tariffs is robust, it is essential for policymakers to carefully consider the broader consequences of such actions. Striking a balance between defending national interests and fostering constructive international relationships will be crucial as Canada navigates these complex trade challenges in the coming years.

After Quakes, Puerto Rico's Electricity Is Back On For Most, But Uncertainty Remains

Puerto Rico Earthquakes continue as a seismic swarm with aftershocks, landslides near Pef1uelas, damage in Ponce and Guayanilla, grid outages from Costa Sur Plant, PREPA recovery, vulnerable buildings post-Hurricane Maria raising safety concerns.

 

Key Points

Recurring seismic events impacting Puerto Rico, causing damage, aftershocks, outages, and displacement.

✅ Seismic swarm with 6.4 and 5.9 magnitude quakes and ongoing aftershocks

✅ Costa Sur Plant offline; PREPA urges conservation amid grid repairs

✅ Older, code-deficient buildings and landslides raise safety risks

 

Some in Puerto Rico are beginning to fear the ground will never stop shaking. The island has been pummeled by hundreds of earthquakes in recent weeks, including the recent 5.9 magnitude temblor, where there were reports of landslides in the town of Peñuelas along the southern coast, rattling residents already on edge from the massive 6.4 magnitude quake, and raising wider concerns about climate risks to the grid in disaster-prone regions.

That was the largest to strike the island in more than a century causing hundreds of structures to crumble, forcing thousands from their homes and leaving millions without power, a scenario echoed by Texas power outages during winter storms too. One person was killed and several others injured.

Utility says 99% of customers have electricity

Puerto Rico's public utility, PREPA, tweeted some welcome news Monday: that nearly all of the homes and businesses it serves have had electric power restored. Still it is urging customers to conserve energy amid utility supply-chain shortages that can slow critical repairs.

Reporting from the port city of Ponce, NPR's Adrian Florido said the Costa Sur Plant, which produces more than 40% of Puerto Rico's electricity, was badly damaged in last week's quake. It remains offline indefinitely, even as grid operators elsewhere have faced California blackout warnings during extreme heat.

He also reports many residents are still reeling from the devastation caused by Hurricane Maria, a deadly Category 4 storm that battered the island in September 2017. The storm exposed the fact that buildings across the island were not up to code, similar to how aging systems have contributed to PG&E power line fires in California. The series of earthquakes are only amplifying fears that structures have been further weakened.

"People aren't coping terribly well," Florido said on NPR's Morning Edition Monday, noting that households elsewhere have endured pandemic power shutoffs and burdensome bills.

Many earthquake victims sleeping outdoors

Florido spoke to one displaced resident, Leticia Espada, who said more than 50 homes in her town of Guayanilla, about an hour drive east of the port city of Ponce, had collapsed.

After sleeping outside for days on her patio following Tuesday's quake, she eventually came to her town's baseball stadium where she's been sleeping on one of hundreds of government-issued cots.

She's like so many others sleeping in open-air shelters, many unwilling to go back to their homes until they've been deemed safe, while even far from disaster zones, brief events like a Northeast D.C. outage show how fragile service can be.

"Thousands of people across several towns sleeping in tents or under tarps, or out in the open, protected by nothing but the shade of a tree with no sense of when these quakes are going to stop," Florido reports.

Russia and Ukraine Accuse Each Other of Violating Energy Ceasefire

Russia-Ukraine Energy Ceasefire Violations escalate as U.S.-brokered truce frays, with drone strikes, shelling, and grid attacks disrupting gas supply and power infrastructure across Kursk, Luhansk, Sumy, and Dnipropetrovsk, prompting sanctions calls.

 

Key Points

Alleged breaches of a U.S.-brokered truce, with both sides striking power grids, gas lines, and critical energy nodes.

✅ Drone and artillery attacks reported on power and gas assets

✅ Both sides accuse each other of breaking truce terms

✅ U.S. mediation faces verification and compliance hurdles

 

Russia and Ukraine have traded fresh accusations regarding violations of a fragile energy ceasefire, brokered by the United States, which both sides had agreed to last month. These new allegations highlight the ongoing tensions between the two nations and the challenges involved in implementing a truce amid global energy instability in such a complex and volatile conflict.

The U.S.-brokered ceasefire had initially aimed to reduce the intensity of the fighting, specifically in the energy sector, where both sides had previously targeted each other’s infrastructure. Despite this agreement, the accusations on Wednesday suggest that both Russia and Ukraine have continued their attacks on each other's energy facilities, a crucial aspect of the ceasefire’s terms.

Russia’s Ministry of Defence claimed that Ukrainian forces had launched drone and shelling attacks in the western Kursk region, cutting power to over 1,500 homes. This attack allegedly targeted key infrastructure, leaving several localities without electricity. Additionally, in the Russian-controlled part of Ukraine's Luhansk region, a Ukrainian drone strike hit a gas distribution station, severely disrupting the gas supply for over 11,000 customers in the area around Svatove.

In response, Ukrainian President Volodymyr Zelensky accused Russia of breaking the ceasefire. He claimed that Russian drone strikes had targeted an energy substation in Ukraine’s Sumy region, while artillery fire had damaged a power line in the Dnipropetrovsk region, leaving nearly 4,000 consumers without power even as Ukraine increasingly leans on electricity imports to stabilize the grid. Ukraine's accusations painted a picture of continued Russian aggression against critical energy infrastructure, a strategy that had previously been a hallmark of Russia’s broader military operations in the war.

The U.S. had brokered the energy truce as a potential stepping stone toward a more comprehensive ceasefire agreement. However, the repeated violations raise questions about the truce’s viability and the broader prospects for peace between Russia and Ukraine. Both sides are accusing each other of undermining the agreement, which had already been delicate due to previous suspicions and mistrust. In particular, the U.S. administration, led by President Donald Trump, has expressed impatience with the slow progress in moving toward a lasting peace, amid debates over U.S. national energy security priorities.

Kremlin spokesperson Dmitry Peskov defended Russia’s stance, emphasizing that President Vladimir Putin had shown a commitment to peace by agreeing to the energy truce, despite what he termed as daily Ukrainian attacks on Russian infrastructure. He reiterated that Russia would continue to cooperate with the U.S., even though the Ukrainian strikes were ongoing. This perspective suggests that Russia remains committed to the truce but views Ukraine’s actions as violations that could potentially derail efforts to reach a more comprehensive ceasefire.

On the other hand, President Zelensky argued that Russia was not adhering to the terms of the ceasefire. He urged the U.S. to take a stronger stance against Russia, including increasing sanctions on Moscow as punishment for its violations. Zelensky’s call for heightened sanctions is a continuation of his efforts to pressure international actors, particularly the U.S. and European countries, to provide greater energy security support for Ukraine’s struggle and to hold Russia accountable for its actions.

The ceasefire’s fragility is also reflected in the differing views between Ukraine and Russia on what constitutes a successful resolution. Ukraine had proposed a full 30-day ceasefire, but President Putin declined, raising concerns about monitoring and verifying compliance with the terms. This disagreement suggests that both sides are not entirely aligned on what a peaceful resolution should look like and how it can be realistically achieved.

The situation is complicated by the broader context of the war, which has now dragged on for over three years. The conflict has seen significant casualties, immense destruction, and deep geopolitical ramifications. Both countries are heavily reliant on their energy infrastructures, making any attack on these systems not only a military tactic but also a form of economic warfare. Energy resources, including electricity and natural gas, have become central to the ongoing conflict, with both sides using them to exert pressure on the other amid Europe's deepening energy crisis that reverberates beyond the battlefield.

As of now, it remains unclear whether the recent violations of the energy ceasefire will lead to a breakdown of the truce or whether the United States will intervene further to restore compliance, even as Ukraine prepares for winter amid energy challenges. The situation remains fluid, and the international community continues to closely monitor the developments. The U.S., which played a central role in brokering the energy ceasefire, has made it clear that it expects both sides to uphold the terms of the agreement and work toward a more permanent cessation of hostilities.

The continued accusations between Russia and Ukraine regarding the breach of the energy ceasefire underscore the challenges of negotiating peace in such a complex and entrenched conflict. While both sides claim to be upholding their commitments, the reality on the ground suggests that reaching a full and lasting peace will require much more than temporary truces. The international community, particularly the U.S., will likely continue to push for stronger actions to enforce compliance and to prevent the conflict from further escalating. The outcome of this dispute will have significant implications for both countries and the broader European energy landscape and security landscape.

Western Canada drought impacting hydropower production as reservoirs run low

Western Canada Hydropower Drought strains British Columbia and Manitoba as reservoirs hit historic lows, cutting hydroelectric output and prompting power imports, natural gas peaking, and grid resilience planning amid climate change risks this winter.

 

Key Points

Climate-driven reservoir lows cut hydro in B.C. and Manitoba, prompting imports and backup gas to maintain reliability.

✅ Reservoirs at multi-year lows cut hydro generation capacity

✅ BC Hydro and Manitoba Hydro import electricity for reliability

✅ Natural gas turbines used; climate change elevates drought risk

 

Severe drought conditions in Western Canada are compelling two hydroelectricity-dependent provinces, British Columbia and Manitoba, to import power from other regions. These provinces, known for their reliance on hydroelectric power, are facing reduced electricity production due to low water levels in reservoirs this autumn and winter as energy-intensive customers encounter temporary connection limits.

While there is no immediate threat of power outages in either province, experts indicate that climate change is leading to more frequent and severe droughts. This trend places increasing pressure on hydroelectric power producers in the future, spurring interest in upgrading existing dams as part of adaptation strategies.

In British Columbia, several regions are experiencing "extreme" drought conditions as classified by the federal government. BC Hydro spokesperson Kyle Donaldson referred to these conditions as "historic," and a first call for power highlights the strain, noting that the corporation's large reservoirs in the north and southeast are at their lowest levels in many years.

To mitigate this, BC Hydro has been conserving water by utilizing less affected reservoirs and importing additional power from Alberta and various western U.S. states. Donaldson confirmed that these measures would persist in the upcoming months.

Manitoba is also facing challenges with below-normal levels in reservoirs and rivers. Since October, Manitoba Hydro has occasionally relied on its natural gas turbines to supplement hydroelectric production as electrical demand could double over the next two decades, a measure usually reserved for peak winter demand.

Bruce Owen, a spokesperson for Manitoba Hydro, reassured that there is no imminent risk of a power shortage. The corporation can import electricity from other regions, similar to how it exports clean energy in high-water years.

However, the cost implications are significant. Manitoba Hydro anticipates a financial loss for the current fiscal year, with more red ink tied to emerging generation needs, the second in a decade, with the previous one in 2021. That year, drought conditions led to a significant reduction in the company's power production capabilities, resulting in a $248-million loss.

The 2021 drought also affected hydropower production in the United States. The U.S. Department of Energy reported a 16% reduction in overall generation, with notable decreases at major facilities like Nevada's Hoover Dam, where production dropped by 25%.

Drought has long been a major concern for hydroelectricity producers, and they plan their operations with this risk in mind. Manitoba's record drought in 1940-41, for example, is a benchmark for Manitoba Hydro's operational planning to ensure sufficient electricity supply even in extreme low-water conditions.

Climate change, however, is increasing the frequency of such rare events, highlighting the need for more robust backup systems such as new turbine investments to enhance reliability. Blake Shaffer, an associate professor of economics at the University of Calgary specializing in electricity markets, emphasized the importance of hydroelectric systems incorporating the worsening drought forecasts due to climate change into their energy production planning.

US looks to decommission Alaskan military reactor

SM-1A Nuclear Plant Decommissioning details the US Army Corps of Engineers' removal of the Fort Greely reactor, Cold War facility dismantling, environmental monitoring, remote-site power history, and timeline to 2026 under a deactivated nuclear program.

 

Key Points

Army Corps plan to dismantle Fort Greely's SM-1A reactor and complete decommissioning of remaining systems by 2026.

✅ Built for remote Arctic radar support during the Cold War

✅ High costs beat diesel; program later deemed impractical

✅ Reactor parts removed; residuals monitored; removal by 2026

 

The US Army Corps of Engineers has begun decommissioning Alaska’s only nuclear power plant, SM-1A, which is located at Fort Greely, even as new US reactors continue to take shape nationwide. The $17m plant closed in 1972 after ten years of sporadic operation. It was out of commission from 1967 to 1969 for extensive repairs. Much of has already been dismantled and sent for disposal, and the rest, which is encased in concrete, is now to be removed.

The plant was built as part of an experimental programme to determine whether nuclear facilities, akin to next-generation nuclear concepts, could be built and operated at remote sites more cheaply than diesel-fuelled plants.

"The main approach was to reduce significant fuel-transportation costs by having a nuclear reactor that could operate for long terms, a concept echoed in the NuScale SMR safety evaluation process, with just one nuclear core," Brian Hearty said. Hearty manages the Army Corps of Engineers’ Deactivated Nuclear Power Plant Program.

#google#

He said the Army built SM-1A in 1962 hoping to provide power reliably at remote Arctic radar sites, where in similarly isolated regions today new US coal plants may still be considered, intended to detect incoming missiles from the Soviet Union at the height of the Cold War. He added that the programme worked but not as well as Pentagon officials had hoped. While SM-1A could be built and operated in a cold and remote location, its upfront costs were much higher than anticipated, and it costs more to maintain than a diesel power plant. Moreover, the programme became irrelevant because of advances in Soviet rocket science and the development of intercontinental ballistic missiles.

Hearty said the reactor was partially dismantled soon after it was shut down. “All of the fuel in the reactor core was removed and shipped back to the Atomic Energy Commission (AEC) for them to either reprocess or dispose of,” he noted. “The highly activated control and absorber rods were also removed and shipped back to the AEC.”

The SM-1A plant produced 1.8MWe and 20MWt, including steam, which was used to heat the post. Because that part of the system was still needed, Army officials removed most of the nuclear-power system and linked the heat and steam components to a diesel-fired boiler. However, several parts of the nuclear system remained, including the reactor pressure vessel and reactor coolant pumps. “Those were either kept in place, or they were cut off and laid down in the tall vapour-containment building there,” Hearty said. “And then they were grouted and concreted in place.” The Corps of Engineers wants to remove all that remains of the plant, but it is as yet unclear whether that will be feasible.

Meanwhile, monitoring for radioactivity around the facility shows that it remains at acceptable levels. “It would be safe to say there’s no threat to human health in the environment,” said Brenda Barber, project manager for the decommissioning. Work is still in its early stages and is due to be completed in 2026 at the earliest. Barber said the Corps awarded the $4.6m contract in December to a Virginia-based firm to develop a long-range plan for the project, similar in scope to large reactor refurbishment efforts elsewhere. Among other things, this will help officials determine how much of the SM-1A will remain after it’s decommissioned. “There will still be buildings there,” she said. “There will still be components of some of the old structure there that may likely remain.”
