German Energy Demand Hits Historic Low Amid Economic Stagnation

Snow-powered nanogenerator harvests static electricity from falling snow using a silicone triboelectric design, enabling energy harvesting, solar panel support during snowfall, and dual-use sensing for weather monitoring and wearable winter sports analytics.

Key Points

A silicone triboelectric device that harvests snowDcharge to generate power and enable sensing.

✅ Triboelectric silicone layer captures charge from falling snow.

✅ Integrates with solar arrays to maintain power during snowfall.

✅ Functions as weather and motion sensor for winter sports.

Scientists from University of California, Los Angeles and McMaster University have invented a nanogenerator that creates electricity from falling snow.

Most Canadians have already seen a mini-version of this, McMaster Prof. Ravi Selvaganapathy told CTV’s Your Morning. “We find that we often get shocked in the winter when it’s dry when we come in into contact with a conductive surface like a doorknob.”

The thin device works by harnessing static electricity: positively-charged, falling snow collides with the negatively-charged silicone device, which produces a charge that’s captured by an electrode.

“You separate the charges and create electricity out of essentially nothing,” Richard Kaner, who holds UCLA’s Dr. Myung Ki Hong Endowed Chair in Materials Innovation and whose lab has explored turning waste into graphene, said in a press release.

“The device can work in remote areas because it provides its own power and does not need batteries or reliance on home storage systems such as the Tesla Powerwall, which store energy for later use,” he said, explaining that the device was 3D printed, flexible and inexpensive to make because of the low cost of silicone.

“It’s also going to be useful in places like Canada, where we get a lot of snow and are pursuing a net-zero grid by 2050 to cut emissions. We can extract energy from the environment,” Selvaganapathy added.

The team, which also included scientists from the University of Toronto, published their findings in Nano Energy journal last year, but a few weeks ago, they revealed the device’s more practical uses.

About 30 per cent of the Earth’s surface is covered by snow each winter, which can significantly limit the energy generated by solar panels, including rooftop solar grids in cold climates.

So the team thought: why not simply harness electricity from the snow whenever the solar panels were covered?

Integrating their device into solar panel arrays could produce a continuous power supply whenever it snows, potentially as part of emerging virtual power plants that aggregate distributed resources, study co-author and UCLA assistant researcher Maher El-Kady explained.

The device also serves as a weather-monitoring station by recording how much snow is falling and from where; as well as the direction and speed of the wind.

The team said they also want to incorporate their device into weather sensors to help them better acquire and transmit electronic signals, supporting initiatives to use AI for energy savings across local grids. They said several Toronto-based companies -- which they couldn’t name -- have expressed interest in partnering with them.

Selvaganapathy said the device would hop on the trend of “sensors being incorporated into what we wear, into our homes and even to detect electricity theft in some markets in order to monitor a lot of the things that are important to us”

But the device’s arguably larger potential use is being integrated into technology to monitor athletes and their performances during winter sports, such as hiking, skiing and cross-country skiing.

Up to now, the movement patterns used during cross-country skiing couldn’t be detected by a smart watch, but this device may be able to.

Scientists such as Kaner believe the technology could usher in a new era of self-monitoring devices to assess an athlete’s performance while they’re running, walking or jumping.

The device is simply a proof of concept and the next step would be figuring out how to generate more electricity and integrate it into all of these potential devices, Selvaganapathy said.

Puerto Rico Microgrid Regulations outline renewable energy, CHP, and storage standards, enabling islanded systems, PREPA interconnection, excess energy sales, and IRP alignment to boost resilience, distributed resources, and community power across the recovering grid.

Key Points

Rules defining microgrids, requiring 75 percent renewables or CHP, and setting interconnection and PREPA fee frameworks.

✅ 75 percent renewables or CHP; hybrids allowed

✅ Registration, engineer inspection, and annual generation reports

✅ PREPA interconnection fees; excess energy sales permitted

The Puerto Rico Energy Commission unveiled 29 pages of proposed regulations last week for future microgrid installations on the island.

The regulations, which are now open for 30 days of public comment, synthesized pages of responses received after a November 10 call for recommendations. Commission chair José Román Morales said it’s the most interest the not-yet four-year-old commission has received during a public rulemaking process.

The goal was to sketch a clearer outline for a tricky-to-define concept -- the term "microgrid" can refer to many types of generation islanded from the central grid -- as climate pressures on the U.S. grid mount and more developers eye installations on the recovering island.

“There’s not a standard definition of what a microgrid is, not even on the mainland,” said Román Morales.

According to the commission's regulation, “a microgrid shall consist, at a minimum, of generation assets, loads and distribution infrastructure. Microgrids shall include sufficient generation, storage assets and advanced distribution technologies, including advanced inverters, to serve load under normal operating and usage conditions.”

All microgrids must be renewable (with at least 75 percent of power from clean energy), combined heat and power (CHP) or hybrid CHP-and-renewable systems. The regulation applies to microgrids controlled and owned by individuals, customer cooperatives, nonprofit and for-profit companies, and cities, but not those owned by the Puerto Rico Electric Power Authority (PREPA). Owners must submit a registration application for approval, including a certification of inspection from a licensed electric engineer, and an annual fuel, generation and sales report that details generation and fuel source, as well as any change in the number of customers served.

Microgrids, like the SDG&E microgrid in Ramona in California, can interconnect with the PREPA system, but if a microgrid will use PREPA infrastructure, owners will incur a monthly fee. That amounts to $25 per customer up to a cap of $250 per month for small cooperative microgrids. The cost for larger systems is calculated using a separate, more complex equation. Operators can also sell excess energy back to PREPA.

Big goals for the island's future grid

In total, 53 groups and companies, including Sunnova, AES, the Puerto Rico Solar Energy Industries Association (PR-SEIA), the Advanced Energy Management Alliance (AEMA), and the New York Smart Grid Consortium, submitted their thoughts about microgrids or, in many cases, broader goals for the island’s future energy system. It was a quick turnaround: The Puerto Rico Energy Commission offered a window of just 10 days to submit advice, although the commission continued to accept comments after the deadline.

“PREC wanted the input as fast as possible because of the urgency,” said AES CEO Chris Shelton.

AES’ plan includes a network of “mini-grids” that could range in size from several megawatts to one large enough to service the entire city of San Juan.

“The idea is, you connect those to each other with transmission so they can have a co-optimized portfolio effect and lower the overall cost,” said Shelton. “But they would be largely autonomous in a situation where the tie-lines between them were broken.”

According to estimates provided in AES’ filing, utility-scale solar installations over 50 megawatts on the island could cost between $40 and $50 per megawatt-hour. Those prices make solar located near load centers an economic alternative to the island’s fossil-fuel generating plants. The utility’s analysis showed that a 10,000-megawatt solar system could replace 12,000 gigawatt-hours of fossil generation, with 25 gigawatt-hours of battery storage leveling out load throughout the day. Puerto Rico’s peak load is 3,000 megawatts.

In other filings, PR-SEIA urged a restructuring of FEMA funds so they’re available for microgrid development. GridWise Alliance wrote that plans should consider cybersecurity, and AEMA recommended the commission develop an integrated resource plan (IRP) that includes distributed energy resources, microgrids and non-wires alternatives.

An air of optimism, though 1.5 million are still without power

After the commission completes the microgrid rulemaking, a new IRP is next on the commission’s to-do list. PREPA must file that plan in July, and regulators are working furiously to make sure it incorporates the recent flood of rebuilding recommendations from the energy industry.

Though the commission has the final say when it comes to approval of the plan, PREPA will lead the IRP process. The utility’s newly formed Transformation Advisory Council (TAC), a group of 11 energy experts, will contribute.

With that group, along with New York’s Resiliency Working Group, lessons from California's grid transition, the Energy Commission, the utility itself, and the dozens of other clean energy experts and entrepreneurs who want to offer their two cents, the energy planning process has a lot of moving parts. But according to Julia Hamm, CEO of the Smart Electric Power Alliance and a member of both the Energy Resiliency Working Group and the TAC, those working to establish standards for Puerto Rico’s future are hitting their stride.

“Certainly over the past three months, it has been a bit of a challenge to ensure that everybody has been coordinating efforts. Just over the past couple of weeks, we’ve seen some good progress on that front. We’re starting to see a lot more communication,” she said, adding that an air of optimism has settled on the process. “The key stakeholders all have a very common vision for Puerto Rico when it comes to the power sector.”

Nisha Desai, a PREPA board member who is liaising with the TAC, affirmed that collaborators are on the same page. “Everyone is violently in agreement that the future of Puerto Rico involves renewables, microgrids and distributed generation,” she said.

The TAC will hold its first in-person meeting in mid-January, and has already consulted with the utility on its formal fiscal plan submission, due January 10.

Though many taking part in the process feel the once-harried recovery is beginning to adopt a more organized approach, Desai acknowledges that “there are a lot of people in Puerto Rico who feel forgotten.”

Puerto Rico’s current generation sits at just 72.6 percent, in a nation facing longer, more frequent outages due to extreme weather. The government recently offered its first estimate that about half the island, 1.5 million residents, remains without power.

In late December and into January, 1,500 more crewmembers from 18 utilities in states as far flung as Minnesota, Missouri and Arizona will land on the island to aid further restoration through mutual aid agreements.

“The system is getting up to speed, getting to 100 percent, but there’s still some instability,” said Román Morales. “Right now it’s a matter of time.”

Philippines Renewable Energy Mini-Grids address rising electricity demand, rolling blackouts, off-grid electrification, and decentralized power in an archipelago, leveraging solar, wind, and hybrid systems to close the generation capacity gap and expand household access.

Key Points

Decentralized solar, wind, and hybrid systems powering off-grid areas to relieve shortages and expand access.

✅ Targets 2.3M unelectrified homes with reliable clean power

✅ Mitigates rolling blackouts via modular mini-grid deployments

✅ Supports energy access, resilience, and grid decentralization

The reason why IRENA made its study in the Philippines is because of the country’s demand for electricity is on a steady rise while the generating capacity lags behind. To provide households the electricity, the government is constrained to implement rolling blackouts in some regions. By 2030, the demand for electricity is projected to reach 30 million kilowatts as compared to 17 million kilowatts which is its current generating capacity.

One of the country’s biggest conglomerations, San Miguel Corporation is accountable for almost 20% of power output. It has power plants that has a 900,000-kW generation capacity. Another corporation in the energy sector, Aboitiz Power, has augmented its facilities as well to keep up with the demand. As a matter fact, even foreign players such as Tokyo Electric Power and Marubeni, as a result of the gradual privatization of the power industry which started in 2001, have built power plants in the country, a challenge mirrored in other regions where electricity for all demands greater investment, yet the power supply remains short.

And so, the IRENA came up with the study entitled “Accelerating the Deployment of Renewable Energy Mini-Grids for Off-Grid Electrification – A Study on the Philippines” to provide a clearer picture of what the current state of the crisis is and lay out possible solutions. It showed that as of 2016, a record year for renewables worldwide, the Philippines has approximately 2.3 million households without electricity. With only 89.6 percent of household electrification, that leaves about 2.36 million homes either with limited power of four to six hours each day or totally without electricity.

By the end of 2017, the Philippine government will have provided 90% of Philippine households with electricity. It is worth mentioning that in 2014, the National Capital Region together with two other regions had received 90 percent electrification. However, some areas are still unable to access power that’s within or above the national average. IRENA’s study has become a source of valuable information and analysis to the Philippines’ power systems and identified ways on how to surmount the challenges involving power systems decentralization, with renewable energy funding supporting those mini-grids which are either powered in parts or in full by renewable energy resources. This, however, does not discount the fact that providing electricity in every household still is an on-going struggle. Considering that the Philippines is an archipelago, providing enough, dependable, and clean modern energy to the entire country, including the remote and isolated islands is difficult. The onset of renewable energy is a viable and cost-effective option to support the implementation of mini-grids, as shown by Ireland's green electricity targets rising rapidly.

Manitoba Hydro rate hikes face public hearings over electricity rates, utility bills, and debt, with impacts on low-income households, Indigenous communities, and Winnipeg services amid credit rating pressure and rising energy costs.

Key Points

Manitoba Hydro seeks 7.9% annual increases to stabilize finances and debt, impacting electricity costs for households.

✅ Proposed hikes: 7.9% yearly through 2023/24

✅ Driven by debt, credit rating declines, rising interest

✅ Disproportionate impact on low-income and Indigenous communities

Hearings began Monday into Manitoba Hydro’s request for consecutive annual rate hikes of 7.9 per cent.  The crown corporation is asking for the steep hikes to commence April 1, 2018.

The increases would continue through 2023/2024, under a multi-year rate plan before dropping to what Hydro calls “sustainable” levels.

Patti Ramage, legal counsel for Hydro, said while she understands no one welcomes the “exceptional” rate increases, the company is dealing with exceptional circumstances.

It’s the largest rate increase Hydro has ever asked for, though a scaled-back increase was discussed later, saying rising debt and declining credit ratings are affecting its financial stability.

President and CEO Kelvin Shepherd said Hydro is borrowing money to fund its interest payments, and acknowledged that isn’t an effective business model.

Hydro’s application states that it will be spending up to 63 per cent of its revenue on paying financial expenses if the current request for rate hikes is not approved.

If it does get the increase it wants, that number could shrink to 45 per cent – which Ramage says is still quite high, but preferable to the alternative.

She cited the need to take immediate action to fix Hydro’s finances instead of simply hoping for the best.

“The worst thing we can do is defer action… that’s why we need to get this right,” Ramage said.

A number of intervenors presented varying responses to Hydro’s push for increased rates, with many focusing on how the hikes would affect Manitobans with lower incomes.

Senwung Luk spoke on behalf of the Assembly of Manitoba Chiefs, and said the proposed rates would hit First Nations reserves particularly hard.

He noted that 44.2 per cent of housing on reserves in the province needs significant improvement, which means electricity use tends to be higher to compensate for the lower quality of infrastructure.

Luk says this problem is compounded by the higher rates of poverty in Indigenous populations, with 76 per cent of children on reserves in Manitoba living below the poverty line.

If the increase goes forward, he said the AMC hopes to see a reduced rate for those living on reserves, despite a recent appeal court ruling on such pricing.

Byron Williams, speaking on behalf of the Consumers Coalition, said the 7.9 per cent increase unreasonably favours the interests of Hydro, and is unjustly biased against virtually everyone else.

In Saskatchewan, the NDP criticized an SaskPower 8 per cent rate hike as unfair to customers, highlighting regional concerns.

Williams said customers using electric space heating would be more heavily targeted by the rate increase, facing an extra $13.14 a month as opposed to the $6.88 that would be tacked onto the bills of those not using electric space heating.

Williams also called Hydro’s financial forecasts unreliable, bringing the 7.9 per cent figure into question.

Lawyer George Orle, speaking for the Manitoba Keewatinowi Okimakanak, said the proposed rate hikes would “make a mockery” of the sacrifices made by First Nations across the province, given that so much of Hydro’s infrastructure is on Indigenous land.

The city of Winnipeg also spoke out against the jump, saying property taxes could rise or services could be cut if the hikes go ahead to compensate for increased, unsustainable electricity costs.

In British Columbia, a BC Hydro 3 per cent increase also moved forward, drawing attention to affordability.

A common theme at the hearing was that Hydro’s request was not backed by facts, and that it was heading towards fear-mongering.

Manitoba Hydro’s CEO begged to differ as he plead his case during the first hearing of a process that is expected to take 10 weeks.

Dragonfly energy sector cyberattacks target ICS and SCADA across critical infrastructure, including the power grid and nuclear facilities, using spearphishing, watering-hole sites, supply-chain compromises, malware, and VPN exploits to gain operational access.

Key Points

Dragonfly APT campaigns target energy firms and ICS to gain grid access, risking manipulation and service disruption.

✅ Breaches leveraged spearphishing, watering-hole sites, and supply chains.

✅ Targeted ICS, SCADA, VPNs to pivot into operational networks.

✅ Aimed to enable power grid manipulation and potential outages.

An October, 2017 report by researchers at Symantec Corp., cited by the U.S. government, has linked recent US power grid cyber attacks to a group of hackers it had code-named "Dragonfly", and said it found evidence critical infrastructure facilities in Turkey and Switzerland also had been breached.

The Symantec researchers said an earlier wave of attacks by the same group starting in 2011 was used to gather intelligence on companies and their operational systems. The hackers then used that information for a more advanced wave of attacks targeting industrial control systems that, if disabled, leave millions without power or water.

U.S. intelligence officials have long been concerned about the security of the country’s electrical grid. The recent attacks, condemned by the U.S. government, striking almost simultaneously at multiple locations, are testing the government’s ability to coordinate an effective response among several private utilities, state and local officials, and industry regulators.

While the core of a nuclear generator is heavily protected, a sudden shutdown of the turbine can trigger safety systems. These safety devices are designed to disperse excess heat while the nuclear reaction is halted, but the safety systems themselves may be vulnerable to attack.

The operating systems at nuclear plants also tend to be legacy controls built decades ago and don’t have digital control systems that can be exploited by hackers.

“Since at least March 2016, Russian government cyber actors… targeted government entities and multiple U.S. critical infrastructure sectors, including the energy, nuclear, commercial facilities, water, aviation, and critical manufacturing sectors,” according to Thursday’s FBI and Department of Homeland Security report. The report did not say how successful the attacks were or specify the targets, but said that the Russian hackers “targeted small commercial facilities’ networks where they staged malware, conducted spearphishing, and gained remote access into energy sector networks.” At least one target of a string of infrastructure attacks last year was a nuclear power facility in Kansas.

Symantec doesn’t typically point fingers at particular nations in its research on cyberattacks, said Eric Chien, technical director of Symantec’s Security Technology and Response division, though he said his team doesn’t see anything it would disagree with in the new federal report. The government report appears to corroborate Symantec’s research, showing that the hackers had penetrated computers and accessed utility control rooms that would let them directly manipulate power systems, he says.

“There were really no more technical hurdles for them to do something like flip off the power,” he said.

And as for the group behind the attacks, Chien said it appears to be relatively dormant for now, but it has gone quiet in the past only to return with new hacks.

“We expect they’re sort of retooling now, and they likely will be back,”

In some cases, Dragonfly successfully broke into the core systems that control US and European energy companies, Symantec revealed.

“The energy sector has become an area of increased interest to cyber-attackers over the past two years,” Symantec said in its report.

“Most notably, disruptions to Ukraine’s power system in 2015 and 2016 were attributed to a cyberattack and led to power outages affecting hundreds of thousands of people. In recent months, there have also been media reports of attempted attacks on the electricity grids in some European countries, as well as reports of companies that manage nuclear facilities in the US being compromised by hackers.

“The Dragonfly group appears to be interested in both learning how energy facilities operate and also gaining access to operational systems themselves, to the extent that the group now potentially has the ability to sabotage or gain control of these systems should it decide to do so. Symantec customers are protected against the activities of the Dragonfly group.”

In recent weeks, senior US intelligence officials said that the Kremlin believes it can launch hacking operations against the West with impunity, including a cyber weapon that can disrupt power grids, according to assessments.

The DHS and FBI report further elaborated: “This campaign comprises two distinct categories of victims: staging and intended targets. The initial victims are peripheral organisations such as trusted third-party suppliers with less-secure networks, referred to as ‘staging targets’ throughout this alert.

“The threat actors used the staging targets’ networks as pivot points and malware repositories when targeting their final intended victims. National Cybersecurity and Communications Integration Center and FBI judge the ultimate objective of the actors is to compromise organisational networks, also referred to as the ‘intended target’.”

According to the US alert, hackers used a variety of attack methods, including spear-phishing emails, watering-hole domains, credential gathering, open source and network reconnaissance, host-based exploitation, and deliberate targeting of ICS infrastructure.

The attackers also targeted VPN software and used password cracking tools.

Once inside, the attackers downloaded tools from a remote server and then carried out a number of actions, including modifying key systems to store plaintext credentials in memory, and built web shells to gain command and control of targeted systems.

“This actors’ campaign has affected multiple organisations in the energy, nuclear, water, aviation, construction and critical manufacturing sectors, with hundreds of victims across the U.S. power grid confirmed,” the DHS said, before outlining a number of steps that IT managers in infrastructure organisations can take to cleanse their systems and defend against Russian hackers. he said.

Nuclear Power Construction Milestones spotlight EPR builds, Hualong One steam generators, APR-1400 grid integration, and VVER startups, with hot functional testing, hydrostatic checks, and commissioning advancing toward fuel loading and commercial operation.

Key Points

Key reactor project steps, from testing and grid readiness to startup, marking progress toward safe commercial operation.

✅ EPR units advance through cold and hot functional testing

✅ Hualong One installs 365-ton steam generators at Fuqing 5

✅ APR-1400 and VVER projects progress toward grid connection

The world’s nuclear power industry has been busy in the new year, with several construction projects, including U.S. reactor builds, reaching key milestones as 2018 began.

EPR Units Making Progress

Four EPR nuclear units are under construction in three countries: Olkiluoto 3 in Finland began construction in August 2005, Flamanville 3 in France began construction in December 2007, and Taishan 1 and 2 in China began construction in November 2009. Each of the new units is behind schedule and over budget, but recent progress may signal an end to some of the construction difficulties.

EDF reported that cold functional tests were completed at Flamanville 3 on January 6. The main purpose of the testing was to confirm the integrity of primary systems, and verify that components important to reactor safety were properly installed and ready to operate. More than 500 welds were inspected while pressure was held greater than 240 bar (3,480 psi) during the hydrostatic testing, which was conducted under the supervision of the French Nuclear Safety Authority.

With cold testing successfully completed, EDF can now begin preparing for hot functional tests, which verify equipment performance under normal operating temperatures and pressures. Hot testing is expected to begin in July, with fuel loading and reactor startup possible by year end. The company also reported that the total cost for the unit is projected to be €10.5 billion (in 2015 Euros, excluding interim interest).

Olkiluoto 3 began hot functional testing in December. Teollisuuden Voima Oyj—owner and operator of the site—expects the unit to produce its first power by the end of this year, with commercial operation now slated to begin in May 2019.

Although work on Taishan 1 began years after Olkiluoto 3 and Flamanville 3, it is the furthest along of the EPR units. Reports surfaced on January 2 that China General Nuclear (CGN) had completed hot functional testing on Taishan 1, and that the company expects the unit to be the first EPR to startup. CGN said Taishan 1 would begin commercial operation later this year, with Taishan 2 following in 2019.

Hualong One Steam Generators Installed

Another Chinese project reached a notable milestone on January 8. China National Nuclear Corp. announced the third of three steam generators had been installed at the Hualong One demonstration project, which is being constructed as Unit 5 at the Fuqing nuclear power plant.

The Hualong One pressurized water reactor unit, also known as the HPR 1000, is a domestically developed design, part of China’s nuclear program, based on a French predecessor. It has a 1,090 MW capacity. The steam generators reportedly weigh 365 metric tons and stand more than 21 meters tall. The first steam generator was installed at Fuqing 5 on November 10, with the second placed on Christmas Eve.

Barakah Switchyard Energized

In the United Arab Emirates, more progress has been made on the four South Korean–designed APR-1400 units under construction at the Barakah nuclear power plant. On January 4, Emirates Nuclear Energy Corp. (ENEC) announced that the switchyard for Units 3 and 4 had been energized and connected to the power grid, a crucial step in Abu Dhabi toward completion. Unit 2’s main power transformer, excitation transformer, and auxiliary power transformer were also energized in preparation for hot functional testing on that unit.

“These milestones are a result of our extensive collaboration with our Prime Contractor and Joint Venture partner, the Korea Electric Power Corporation (KEPCO),” ENEC CEO Mohamed Al Hammadi said in a press release. “Working together and benefitting from the experience gained when conducting the same work on Unit 1, the teams continue to make significant progress while continuing to implement the highest international standards of safety, security and quality.”

In 2017, ENEC and KEPCO achieved several construction milestones including installation and concrete pouring for the reactor containment building liner dome section on Unit 3, and installation of the reactor containment liner plate rings, reactor vessel, steam generators, and condenser on Unit 4.

Construction began on the four units (Figure 1) in July 2012, May 2013, September 2014, and September 2015, respectively. Unit 1 is currently undergoing commissioning and testing activities while awaiting regulatory review and receipt of the unit’s operating license from the Federal Authority for Nuclear Regulation, before achieving 100% power in a later phase. According to ENEC, Unit 2 is 90% complete, Unit 3 is 79% complete, and Unit 4 is 60% complete.

VVER Units Power Up

On December 29, Russia’s latest reactor to commence operation—Rostov 4 near the city of Volgodonsk—reached criticality, as other projects like Leningrad II-1 advance across the fleet, and was operated at its minimum controlled reactor power (MCRP). Criticality is a term used in the nuclear industry to indicate that each fission event in the reactor is releasing a sufficient number of neutrons to sustain an ongoing series of reactions, which means the neutron population is constant and the chain reaction is stable.

“The transfer to the MCRP allows [specialists] to carry out all necessary physical experiments in the critical condition of [the] reactor unit (RU) to prove its design criteria,” Aleksey Deriy, vice president of Russian projects for ASE Engineering Co., said in a press release. “Upon the results of the experiments the specialists will decide on the RU powerup.”

Rostov 4 is a VVER-1000 reactor with a capacity of 1,000 MW. The site is home to three other VVER units: Unit 1 began commercial operation in 2001, Unit 2 in 2010, and Unit 3 in 2015.
