Nuclear watchdog group names new director

Quinone-mediated fuel cell uses a bio-inspired organic shuttle to carry electrons and protons to a nearby cobalt catalyst, improving hydrogen conversion, cutting platinum dependence, and raising efficiency while lowering costs for clean electricity.

Key Points

An affordable, bio-inspired fuel cell using an organic quinone shuttle and cobalt catalyst to move electrons efficiently

✅ Organic quinone shuttles electrons to a separate cobalt catalyst

✅ Reduces platinum use, lowering cost of hydrogen power

✅ Bio-inspired design aims to boost efficiency and durability

Fuel cells have long been viewed as a promising power source. But most fuel cells are too expensive, inefficient, or both. In a new approach, inspired by biology, a team has designed a fuel cell using cheaper materials and an organic compound that shuttles electrons and protons.

Fuel cells have long been viewed as a promising power source. These devices, invented in the 1830s, generate electricity directly from chemicals, such as hydrogen and oxygen, and produce only water vapor as emissions. But most fuel cells are too expensive, inefficient, or both.

In a new approach, inspired by biology and published today (Oct. 3, 2018) in the journal Joule, a University of Wisconsin-Madison team has designed a fuel cell using cheaper materials and an organic compound that shuttles electrons and protons.

In a traditional fuel cell, the electrons and protons from hydrogen are transported from one electrode to another, where they combine with oxygen to produce water. This process converts chemical energy into electricity. To generate a meaningful amount of charge in a short enough amount of time, a catalyst is needed to accelerate the reactions.

Right now, the best catalyst on the market is platinum -- but it comes with a high price tag, and while advances like low-cost heat-to-electric materials show promise, they address different conversion pathways. This makes fuel cells expensive and is one reason why there are only a few thousand vehicles running on hydrogen fuel currently on U.S. roads.

Shannon Stahl, the UW-Madison professor of chemistry who led the study in collaboration with Thatcher Root, a professor of chemical and biological engineering, says less expensive metals can be used as catalysts in current fuel cells, but only if used in large quantities. "The problem is, when you attach too much of a catalyst to an electrode, the material becomes less effective," he says, "leading to a loss of energy efficiency."

The team's solution was to pack a lower-cost metal, cobalt, into a reactor nearby, where the larger quantity of material doesn't interfere with its performance. The team then devised a strategy to shuttle electrons and protons back and forth from this reactor to the fuel cell.

The right vehicle for this transport proved to be an organic compound, called a quinone, that can carry two electrons and protons at a time. In the team's design, a quinone picks up these particles at the fuel cell electrode, transports them to the nearby reactor filled with an inexpensive cobalt catalyst, and then returns to the fuel cell to pick up more "passengers."

Many quinones degrade into a tar-like substance after only a few round trips. Stahl's lab, however, designed an ultra-stable quinone derivative. By modifying its structure, the team drastically slowed down the deterioration of the quinone. In fact, the compounds they assembled last up to 5,000 hours -- a more than 100-fold increase in lifetime compared to previous quinone structures.

"While it isn't the final solution, our concept introduces a new approach to address the problems in this field," says Stahl. He notes that the energy output of his new design produces about 20 percent of what is possible in hydrogen fuel cells currently on the market. On the other hand, the system is about 100 times more effective than biofuel cells that use related organic shuttles.

The next step for Stahl and his team is to bump up the performance of the quinone mediators, allowing them to shuttle electrons more effectively and produce more power. This advance would allow their design to match the performance of conventional fuel cells, but with a lower price tag.

"The ultimate goal for this project is to give industry carbon-free options for creating electricity, including thermoelectric materials that harvest waste heat," says Colin Anson, a postdoctoral researcher in the Stahl lab and publication co-author. "The objective is to find out what industry needs and create a fuel cell that fills that hole."

This step in the development of a cheaper alternative could eventually be a boon for companies like Amazon and Home Depot that already use hydrogen fuel cells to drive forklifts in their warehouses.

"In spite of major obstacles, the hydrogen economy, with efforts such as storing electricity in pipelines in Europe, seems to be growing," adds Stahl, "one step at a time."

Financial support for this project was provided by the Center for Molecular Electrocatalysis, an Energy Frontier Research Center funded by the U.S. Department of Energy, Office of Science, Office of Basic Energy Sciences, and by the Wisconsin Alumni Research Foundation (WARF) through the WARF Accelerator Program.

COVID-19 Impact on US Electric Grid: utilities, ERCOT, PJM, and MISO brace for load shifts as remote work rises, industrial demand falls, and nuclear plants enforce pandemic planning to maintain reliability and resilience.

Key Points

Pandemic-driven changes in electricity demand and operations as utilities shift to remote work and reduced industrial use.

✅ Utilities enact remote work and suspend disconnections

✅ Grid operators model load shifts and maintain reliability

✅ Nuclear plants sustain operations with pandemic protocols

Operators of the nation's electric grid and energy companies are bracing for the spread of a virus that is undercutting power demand in countries across Asia and Europe as daily activities grind to a halt.

Owners of U.S. utilities and nuclear plants are canceling events, halting travel, pushing remote work and testing ill workers to slow the spread of the novel coronavirus.

So far, grid operators in the United States say no substantial effect on the electricity demand has emerged, but that could change, even though some reports indicate the U.S. grid is safe for now amid COVID-19. Texas' main grid operator, the Electric Reliability Council of Texas (ERCOT), expressed uncertainty when asked whether it will see changes in demand patterns for power due to the virus.

"It's too early to tell," Leslie Sopko, a spokeswoman for ERCOT, said in an email.

The virus has already taken a toll on power demand overseas. The chairman of Japan's federation of electric utilities and president of Chubu Electric Power Co., Satoru Katsuno, told reporters Friday the country's power demand has weakened as industrial activity slows due to the outbreak, according to Reuters.

The news outlet similarly reported China's industrial power demand this year may decline as the virus curtailed factory output and prevented some employees from returning to work. And, according to Bloomberg, power use in Italy slumped 7.4% last week after the government there shut down schools and told workers to remain home, while Ontario electricity demand also declined as people stayed home.

U.S. utility executives said the sector is well prepared and has faced the threat of spreading infections before. More than a decade ago, global virus scares like SARS pushed companies to hammer out extensive disaster planning, and those have stuck.

"A lot of the foundational work on contingency planning is actually rooted in pandemic planning because of those experiences in the mid-2000s," Scott Aaronson, the Edison Electric Institute's vice president of security and preparedness, told E&E News. "There is a good body of work and a lot of planning and exercises that have gone into being able to operate through these challenges."

Keeping the nation's electric grid running is a top priority at the Department of Energy, said Chris Fall, the agency's point person for COVID-19, which the new coronavirus causes. "Our responsibility is to make sure the electrical grid is resilient and working," said Fall, who directs the department's Office of Science.

He told an agency podcast, called "Direct Current," that the department is working with the private sector and other elements of the energy system. "Obviously we are connected with other agencies like Homeland Security or [the Federal Energy Regulatory Commission] on things like the electrical grid and making sure we have power, and if those people get sick or impacted, we have backups for all of that," he said.

According to a bulletin EEI released on the issue, 40% of a company's employees could be out sick, be quarantined or stay home to care for sick family members. And pandemics may prevent "traditional mutual assistance programs that help companies restore service after natural disasters and weather events," EEI said, such as restoring power in Florida after major storms.

The utility sector is also juggling the needs of its customers. Many major utilities across the nation have vowed to suspend shut-offs and keep power, heat and water on for all customers — a particular concern for people who may be out of work and cannot afford to pay their bills. Companies are also suspending disconnections for nonpayment, some under direction from officials and regulators in states like Ohio and Connecticut, while in Canada Hydro One's peak rate policy has drawn attention among self-isolating customers.

Like other businesses preparing for pandemics, utilities focus on keeping the workforce healthy and operations running. But EEI's Aaronson noted that a key difference with keeping critical infrastructure humming is the possible requirement for the sheltering in place of essential employees who are unable to do their jobs from home, as some operators contemplate locking down key staff at work sites to ensure continuity.

Grid operators are also well-equipped to handle shifts in power demand, and he acknowledged the sector could see changes as more offices and businesses move to remote working. He compared it to the load demand shifts between weekdays and weekends.

"So on the weekends, you're going to have a lot of people at home," Aaronson said. "During the week, it's people in offices. But generally speaking, the ability to have that resiliency and redundancy, the ability to shift resources and the way the grid balances, that is not going to change."

Electricity demand from high-intensity industries like manufacturing or theme parks like Disneyland could also wane, he added, even as electricity inequality in California influences who is most affected.

"It's not just a load shift to the residential, but it's also the load drop in some cases," Aaronson said. "Some of the commercial and industrial customers are going to be working a little bit less than they are presently."

Nuclear plants
Work is continuing at the Plant Vogtle nuclear construction project after Georgia Power Co. announced that one of the site workers is being tested for the coronavirus. The utility does not have the results of that test, a Georgia Power spokesman said late yesterday afternoon. The person works primarily in an office setting and is not on the construction site where two nuclear reactors are being built.

A second worker was tested Saturday, and those results were negative, spokesman John Kraft told E&E News.

Vogtle boasts a high worker count of 9,000 across the entire construction site, which includes office buildings. This is mostly craft laborers, but there are also administrators, executives and Nuclear Regulatory Commission safety inspectors.

A number of contractors and vendors are also on site given the complexity of the project.

Employees who were near the office worker being tested have been sent home until the company receives results. If the test is positive, then those workers will stay home for 14 days, Georgia Power said.

"The company is taking every action to prepare for impacts of the COVID-19 pandemic," Kraft said in a statement. This includes using advice from medical professionals and the Atlanta-based Centers for Disease Control and Prevention.

Georgia Power, owned by Atlanta-based Southern Co., informed regulators at the NRC that a worker was being tested. The federal commission itself has pandemic plans in place to ensure continued oversight, including robust work-from-home capabilities and "social distancing" practices to limit close contact among employees at headquarters.

NRC spokesman Scott Burnell said in an email that telework is not unusual for the agency, and about 75% of its workforce is already equipped to work remotely. The commission tested its telework readiness Friday. Some positions require workers to stay on-site to ensure safe reactor operations, Burnell added.

The nuclear industry has maintained pandemic preparedness plans and procedures since 2006, which have been shared with federal agencies, according to Mary Love, a spokeswoman for the Nuclear Energy Institute. "NEI members are participating in weekly calls to facilitate communications, coordination and best practices," she said.

According to NEI statistics, each plant averages 500 to 1,000 workers. While not every position is essential to operations, some areas like the control room cannot be conducted remotely.

"We know that nuclear power plant operations and the availability of electric service will be tremendously important in minimizing the impact of the situation on the general public," Love added. "We are confident, based on extensive planning, that the industry will continue to operate nuclear plants safely as this event unfolds."

Grid operators
Hundreds of workers responsible for overseeing critical operations of the U.S. electric grid are being encouraged to work from home, their offices are being sanitized, and in-person meetings are being moved online.

PJM Interconnection, the nation's largest grid operator covering some 65 million people across Mid-Atlantic and Midwest states, said Friday a forecast on load changes was not yet available.

PJM has moved all stakeholder meetings online. Employee travel has been suspended, as have external visits to its headquarters in Valley Forge, Pa.

Employees "are equipped to work remotely, if necessary, to maintain business continuity," and PJM "is prepared and able to run and support all market applications from its campus or remotely, as needed," the operator said.

"PJM recognizes that these measures have significant impacts to our staff, members and stakeholders," PJM said on its coronavirus response webpage. "We are dedicated to striking a balance between those impacts and our number one priority — the reliability of the grid."

Still pending at the operator is a decision about its annual meeting in Chicago at the beginning of May. That decision will be made by April 3, PJM said.

The Midcontinent Independent System Operator (MISO), which runs the bulk power grid across 15 states and the Canadian province of Manitoba, is also holding meetings via conference call or online and restricting all business travel.

MISO has encouraged "nonessential" employees to work remotely, leaving only those who actively monitor and manage the operation of the grid working on-site.

The grid operator employs nearly 1,000 people, including 780 at its headquarters in Carmel, Ind.

A board meeting set for the last week of March in New Orleans hasn't yet been canceled, with a final decision on whether to move forward with the meeting expected today.

MISO said it hasn't encountered other changes in normal operations and has not seen significant shifts in electricity demand.

In Texas, ERCOT has about 750 employees, mostly at its campus in the city of Taylor. ERCOT's Sopko said the grid operator is encouraging employees who are not required to be on-site to work from home. The policy is voluntary at this time, but that could change quickly, she said Friday.

ERCOT is also taking extra steps to keep workers safe, including alternating use of facilities, encouraging social distancing and imposing control room measures as part of its pandemic planning, she added.

Energy companies
In the Midwest, utilities including DTE Energy Co., Commonwealth Edison, Consumers Energy and Ameren Corp. said they're following CDC guidance and working with state and local officials to help slow the spread of the virus. That means asking employees who can do their jobs at home to do so, restricting visitors to company offices, canceling large assemblies and nonessential business travel, and holding meetings by phone or online.

Chicago-based ComEd, which serves 4 million customers, is imposing a moratorium on service disconnections and waiving new late payment charges through at least May 1, in addition to working with customers who are facing financial hardships on a case-by-case basis to establish payment arrangements and identify energy assistance options, spokesman Paul Elsberg said.

Many of the Southeast's major energy companies are also curbing travel and encouraging telework, among other steps, in response to the coronavirus.

For Southern Co., this includes its Georgia Power unit; Southern Power; and employees of Southern Company Gas, who are in Illinois, Tennessee and Virginia. Southern has not extended the policies to its Alabama and Mississippi electric companies, spokesman Schuyler Baehman said.

Charlotte, N.C.-based Duke Energy Corp. has suspended all business travel unless workers are traveling by car. The energy giant also is encouraging its employees to rethink their own vacations if upcoming trips take them out of the country.

"Circumstances are changing rapidly around the world," the company said in a statement.

For workers who must come to the office, or work at power plants or on the lines, utilities are doubling down on disinfectant in those areas.

"We're also reminding our employees that we provide a very critical service; we need you well, we need you able," said Le-Ha Anderson, a spokeswoman for Richmond, Va.-based Dominion Energy Inc.

Dominion started asking employees a few weeks ago to take mobile devices home and make sure they have what they need to work remotely. Anyone who has traveled to one of the CDC-identified hot spots is asked to stay home for 14 days with no questions asked, Anderson said.

The federally owned Tennessee Valley Authority has reviewed and updated its plans on how it will operate during a pandemic but has not yet reached the point to have employees telework if they are able to do so.

"We come at this at a very phased approach," TVA spokesman Jim Hopson said. "We can't just shut the doors."

State utility commissions, too, have begun taking steps. In response to a state of emergency declared by Ohio Gov. Mike DeWine (R), the Public Utilities Commission of Ohio on Thursday directed utilities to act where possible to avoid suspending service to customers.

Will Seuffert, executive secretary of the Minnesota Public Utilities Commission, said in an email that the regulator has canceled all public hearings and agenda meetings for the next two weeks and has been supporting telework "throughout the agency" in response to the virus.

Vehicle-to-Grid (V2G) enables EV batteries to provide grid balancing, flexibility, and demand response, integrating renewables with bidirectional charging, reducing peaker plant reliance, and unlocking distributed energy storage from millions of connected electric vehicles.

Key Points

Vehicle-to-Grid (V2G) lets EVs export power via bidirectional charging to balance grids and support renewables.

✅ Turns parked EVs into distributed energy storage assets

✅ Delivers balancing services and demand response to the grid

✅ Cuts peaker plant use and supports renewable integration

“There are already many Gigawatt-hours of batteries on wheels”, which could be used to provide balance and flexibility to electrical grids, if the “ultimate potential” of vehicle-to-grid (V2G) technology could be harnessed.

That’s according to a panel of experts and stakeholders convened by our sister site Current±, which covers the business models and technologies inherent to the low carbon transition to decentralised and clean energy. Focusing mainly on the UK grid but opening up the conversation to other territories and the technologies themselves, representatives including distribution network operator (DNO) Northern Powergrid’s policy and markets director and Nissan Europe’s director of energy services debated the challenges, benefits and that aforementioned ultimate potential.

Decarbonisation of energy systems and of transport go hand-in-hand amid grid challenges from rising EV uptake, with vehicle fuel currently responsible for more emissions than electricity used for energy elsewhere, as Ian Cameron, head of innovation at DNO UK Power Networks says in the Q&A article.

“Furthermore, V2G technology will further help decarbonisation by replacing polluting power plants that back up the electrical grid,” Marc Trahand from EV software company Nuvve Corporation added, pointing to California grid stability initiatives as a leading example.

While the panel states that there will still be a place for standalone utility-scale energy storage systems, various speakers highlighted that there are over 20GWh of so-called ‘batteries on wheels’ in the US, capable of powering buildings as needed, and up to 10 million EVs forecast for Britain’s roads by 2030.

“…it therefore doesn’t make sense to keep building expensive standalone battery farms when you have all this capacity on wheels that just needs to be plugged into bidirectional chargers,” Trahand said.

Calgary Winter Energy Usage Surge highlights soaring electricity demand, added megawatt-hours, and grid reliability challenges driven by extreme cold, heating loads, and climate change, with summer air conditioning also shifting seasonal peaks.

Key Points

A spike in Calgary's power use from extreme cold, adding 22k MWh and testing reliability as heating demand rises.

✅ +22,000 MWh vs Feb 2018 amid fourth-coldest February

✅ Heating loads spike; summer A/C now drives peak demand

✅ Grid reliability monitored; more solar and green resources ahead

February was so cold in Calgary that the city used enough extra energy to power 3,400 homes for a whole year, echoing record-breaking demand in B.C. in 2021 during severe cold.

Enmax Power Corporation, the primary electricity utility in the city, says the city 's energy consumption was up 22,000 megawatt hours last month compared with Februray 2018.

"We've seen through this cold period our system has held up very well. It's been very reliable," Enmax vice-president Andre van Dijk told the Calgary Eyeopener on Friday. "You know, in the absence of a windstorm combined with cold temperatures and that sort of thing, the system has actually held up pretty well."

The past month was the fourth coldest in Calgary's history, and similar conditions have pushed all-time high demand in B.C. in recent years across the West. The average temperature for last month was –18.1 C. The long-term average for February is –5.4 C.

Watching use, predicting issues

The electricity company monitors demand and load on a daily basis, always trying to predict issues before they happen, van Dijk said, and utilities have introduced winter payment plans to help customers manage bills during prolonged cold.

One of the issues they're watching is climate change, and how extreme temperatures and weather affect both the grid's reliability, as seen when Quebec shattered consumption records during cold snaps, and the public's energy use.

The colder it gets, the higher you turn up the heat. The hotter it is, the more you use air conditioning.

He also noted that using fuels then contributes to climate change, creating a cycle.

​"We are seeing variations in temperature and we've seen large weather events across the continent, across the world, in fact, that impact electrical systems, whether that's flooding, as we've experienced here, or high winds, tornadoes," van Dijk said.

"Climate change and changing weather patterns have definitely had had an impact on us as an electrical industry."

In 2012, he said, Calgary switched from using the most power during winter to using the most during summer, in large part due to air conditioning, he said.

"Temperature is a strong influencer of energy consumption and of our demand," van Dijk said.

Christmas tree lights have also become primarily LED, van Dijk said, which cuts down on a big energy draw in the winter.

He said he expects more solar and other green resources will be added into the electrical system in the future to mitigate how much the increasingly levels of energy use impact climate change, and to help moderate electricity costs in Alberta over time.

TEPCO Kashiwazaki-Kariwa restart plan clears NRA fitness review, anchored by a seven-point safety code, Niigata consent, Fukushima lessons, seismic risk analysis, and upgrades to No. 6 and No. 7 reactors, each rated 1.35 GW.

Key Points

TEPCO's plan to restart Kashiwazaki-Kariwa under NRA rules, pending Niigata consent and upgrades to Units 6 and 7.

✅ NRA deems TEPCO fit; legally binding seven-point safety code

✅ Local consent required: Niigata review of evacuation and health impacts

✅ Initial focus on Units 6 and 7; 1.35 GW each, seismic upgrades

Tokyo Electric Power Co. cleared a major regulatory hurdle toward restarting a nuclear power plant in Niigata Prefecture, but the utility’s bid to resume its operations still hangs in the balance of a series of political approvals.

The government’s nuclear watchdog concluded Sept. 23 that the utility is fit to operate the plant, based on new legally binding safety rules TEPCO drafted and pledged to follow, even as nuclear projects worldwide mark milestones across different regulatory environments today. If TEPCO is found to be in breach of those regulations, it could be ordered to halt the plant’s operations.

The Nuclear Regulation Authority’s green light now shifts the focus over to whether local governments will agree in the coming months to restart the Kashiwazaki-Kariwa plant.

TEPCO is keen to get the plant back up and running. It has been financially reeling from the closure of its nuclear plants in Fukushima Prefecture following the triple meltdown at the Fukushima No. 1 nuclear plant in 2011 triggered by the earthquake and tsunami disaster.

In parallel, Japan is investing in clean energy innovations such as a large hydrogen system being developed by Toshiba, Tohoku Electric Power and Iwatani.

The company plans to bring the No. 6 and No. 7 reactors back online at the Kashiwazaki-Kariwa nuclear complex, which is among the world’s largest nuclear plants, amid China’s nuclear energy continuing on a steady development track in the region.

The two reactors each boast 1.35 gigawatts in output capacity, while Kenya’s nuclear plant aims to power industry as part of that country’s expansion. They are the newest of the seven reactors there, first put into service between 1996 and 1997.

TEPCO has not revealed specific plans yet on what to do with the older five reactors.

In 2017, the NRA cleared the No. 6 and No. 7 reactors under the tougher new reactor regulations established in 2013 in response to the Fukushima nuclear disaster, while jurisdictions such as Ontario support continued operation at Pickering under strict oversight.

It also closely scrutinized the operator’s ability to run the Niigata Prefecture plant safely, given its history as the entity responsible for the nation’s most serious nuclear accident.

After several rounds of meetings with top TEPCO managers, the NRA managed to hold the utility’s feet to the fire enough to make it pledge, in writing, to abide by a new seven-point safety code for the Kashiwazaki-Kariwa plant.

The creation of the new code, which is legally binding, is meant to hold the company accountable for safety measures at the facility.

“As the top executive, the president of TEPCO will take responsibility for the safety of nuclear power,” one of the points reads. “TEPCO will not put the facility’s economic performance above its safety,” reads another.

The company promised to abide by the points set out in writing during the NRA’s examination of its safety regulations.

TEPCO also vowed to set up a system where the president is directly briefed on risks to the nuclear complex, including the likelihood of earthquakes more powerful than what the plant is designed to withstand. It must also draft safeguard measures to deal with those kinds of earthquakes and confirm whether precautionary steps are in place.

The utility additionally pledged to promptly release public records on the decision-making process concerning crucial matters related to nuclear safety, and to preserve the documents until the facility is decommissioned.

TEPCO plans to complete its work to reinforce the safety of the No. 7 reactor in December. It has not set a definite deadline for similar work for the No. 6 reactor.

To restart the Kashiwazki-Kariwa plant, TEPCO needs to obtain consent from local governments, including the Niigata prefectural government.

The prefectural government is studying the plant’s safety through a panel of experts, which is reviewing whether evacuation plans are adequate as off-limits areas reopen and the health impact on residents from the Fukushima nuclear disaster.

Niigata Governor Hideyo Hanazumi said he will not decide on the restart until the panel completes its review.

The nuclear complex suffered damage, including from fire at an electric transformer, when an earthquake it deemed able to withstand hit in 2007.

Zaporizhzhia Nuclear Plant Restart signals new high-voltage transmission lines to Mariupol, Rosatom grid integration, and IAEA-monitored safety amid occupied territory risks, cooling system shortfalls after the Kakhovka dam collapse, and disputed international law.

Key Points

A Russian plan to reconnect and possibly restart ZNPP via power lines, despite IAEA safety, cooling, and legal risks.

✅ 80 km high-voltage link toward Mariupol confirmed by imagery

✅ IAEA warns of safety risks and militarization at the site

✅ Cooling capacity limited after Kakhovka dam destruction

Russia is actively constructing new power lines to facilitate the restart of the Zaporizhzhia Nuclear Power Plant (ZNPP), Europe's largest nuclear facility, which it seized from Ukraine in 2022. Satellite imagery analyzed by Greenpeace indicates the construction of approximately 80 kilometers (50 miles) of high-voltage transmission lines and pylons connecting the plant to the Russian-controlled port city of Mariupol. This development marks the first tangible evidence of Russia's plan to reintegrate the plant into its energy infrastructure.

Strategic Importance of Zaporizhzhia Nuclear Power Plant

The ZNPP, located on the eastern bank of the Dnipro River in Enerhodar, was a significant asset in Ukraine's energy sector before its occupation. Prior to the war, the plant was connected to Ukraine's national grid, which later saw resumed electricity exports, via four 750-kilovolt lines, two of which passed through Ukrainian-controlled territory and two through areas under Russian control. The ongoing conflict has damaged these lines, complicating efforts to restore the plant's operations.

In March 2022, Russian forces captured the plant, and by 2023, all six of its reactors had been shut down. Despite this, Russian authorities have expressed intentions to restart the facility. Rosatom, Russia's state nuclear corporation, has identified replacing the power grid as one of the critical steps necessary for resuming operations, even as Ukraine pursues more resilient wind power to bolster its energy mix.

Environmental and Safety Concerns

The construction of new power lines and the potential restart of the ZNPP have raised significant environmental and safety concerns, as the IAEA has warned of nuclear risks from grid attacks in recent assessments. Greenpeace has reported that the plant's cooling system has been compromised due to the destruction of the Kakhovka Reservoir dam in 2023, which previously supplied cooling water to the plant. Currently, the plant relies on wells for cooling, which are insufficient for full-scale operations.

Additionally, the International Atomic Energy Agency (IAEA) has expressed concerns about the militarization of the plant. Reports indicate that Russian forces have established defensive positions and trenches around the facility, with mines found at ZNPP by UN inspectors, raising the risk of accidents and complicating efforts to ensure the plant's safety.

International Reactions and Legal Implications

Ukraine and the international community have condemned Russia's actions as violations of international law and Ukrainian sovereignty. Ukrainian officials have argued that the construction of power lines and the potential restart of the ZNPP constitute illegal activities in occupied territory. The IAEA has called for a ceasefire to allow for necessary safety improvements and to facilitate inspections of the plant, as a possible agreement on power plant attacks could underpin de-escalation efforts.

The United States has also expressed concerns, with President Donald Trump reportedly proposing the inclusion of the ZNPP in peace negotiations, which sparked controversy among Ukrainian and international observers, even suggesting the possibility of transferring control to American companies. However, Russia has rejected such proposals, reaffirming its intention to maintain control over the facility.

The construction of new power lines to the Zaporizhzhia Nuclear Power Plant signifies Russia's commitment to reintegrating the facility into its energy infrastructure. However, this move raises significant environmental, safety, and legal concerns, and a proposal to control Ukraine's nuclear plants remains controversial among stakeholders. The international community continues to monitor the situation closely, urging for adherence to international laws and standards to prevent potential nuclear risks.
