Heartbeats may power future pacemakers

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.

Cyprus Electricity Interconnectors link the island to the EU grid via EuroAsia and EuroAfrica projects, enabling renewable energy trade, subsea transmission, market liberalization, and stronger energy security and diplomacy across the region.

Key Points

Subsea links connecting Cyprus to Greece, Israel and Egypt for EU grid integration, renewable trade and energy security.

✅ Connects EU, Israel, Egypt via EuroAsia and EuroAfrica

✅ Enables renewables integration and market liberalization

✅ Strengthens energy security, investment, and diplomacy

Electricity interconnectors bridging Cyprus with the broader geographical region, mirroring projects like the Ireland-France grid link already underway in Europe, are crucial for its diplomacy while improving its game to become a clean energy hub.

In an interview with Phileleftheros daily, Andreas Poullikkas, chairman of the Cyprus Energy Regulatory Authority (CERA), said electricity cables such as the EuroAsia Interconnector and the EuroAfrica Interconnector, could turn the island into an energy hub, creating investment opportunities.

“Cyprus, with proper planning, can make the most of its energy potential, turning Cyprus into an electricity producer-state and hub by establishing electrical interconnections, such as the EuroAsia Interconnector and the EuroAfrica Interconnector,” said Poullikkas.

He said these electricity interconnectors, “will enable the island to become a hub for electricity transmission between the European Union, Israel and Egypt, with developments such as the Israel Electric Corporation settlement highlighting regional dynamics, while increasing our energy security”.

Poullikkas argued it will have beneficial consequences in shaping healthy conditions for liberalising the country’s electricity market and economy, facilitating the production of electricity with Renewable Energy Sources and supporting broader efforts like the UK grid transformation toward net zero.

“Electricity interconnections are an excellent opportunity for greater business flexibility in Cyprus, ushering new investment opportunities, as seen with the Lake Erie Connector investment across North America, either in electricity generation or other sectors. Especially at a time when any investment or financial opportunity is welcomed.”

He said Cyprus’ energy resources are a combination of hydrocarbon deposits and renewable energy sources, such as solar.

This combination offers the country a comparative advantage in the energy sector.

Cyprus can take advantage of the development of alternative supply routes of the EU, as more links such as new UK interconnectors come online.

Poullikkas argued that as energy networks are developing rapidly throughout the bloc, serving the ever-increasing needs for electricity, and aligning with the global energy interconnection vision highlighted in recent assessments, the need to connect Cyprus with its wider geographical area is a matter of urgency.

He argues the development of important energy infrastructure, especially electricity interconnections, is an important catalyst in the implementation of Cyprus goals, while recognising how rule changes like Australia's big battery market shift can affect storage strategies.

“It should also be a national political priority, as this will help strengthen diplomatic relations,” added Poullikkas.

Implementing the electricity interconnectors between Israel, Cyprus and Greece through Crete and Attica (EuroAsia Interconnector) has been delayed by two years.

He said the delay was brought about after Greece decided to separate the Crete-Attica section of the interconnection and treat as a national project.

Poullikkas stressed the Greek authorities are committed to ensuring the connection of Cyprus with the electricity market of the EU.

“All the required permits have been obtained from the competent authorities in Cyprus and upon the completion of the procedures with the preferred manufacturers, construction of the Cyprus-Crete electrical interconnection will begin before the end of this year. Based on current data, the entire interconnection is expected to be implemented in 2023”.

“The EuroAfrica Interconnector is in the pre-works stage, all project implementation studies have already been completed and submitted to the competent authorities, including cost and benefit studies”.

EuroAsia Interconnector is a leading EU project of common interest (PCI), also labelled as an “electricity highway” by the European Commission.

It connects the national grids of Israel, Cyprus and Greece, creating a reliable energy bridge between the continents of Asia and Europe allowing bi-directional transmission of electricity.

The cost of the entire subsea cable system, at 1,208km, the longest in the world and the deepest at 3,000m below sea level, is estimated at €2.5 bln.

Construction costs for the first phase of the Egypt-Cyprus interconnection (EuroAfrica) with a Stage 1 transmission capacity of 1,000MW is estimated at €1bln.

The Cyprus-Greece (Crete) interconnection, as well as the Egypt-Cyprus electricity interconnector, will both be commissioned by December 2023.

Minnesota Carbon-Free Power by 2050 aims to shift utilities to renewable energy, wind and solar, boosting efficiency while managing grid reliability, emissions, and costs under a clean energy mandate and statewide climate policy.

Key Points

A statewide goal to deliver 100% carbon-free power by 2050, prioritizing renewables, efficiency, and grid reliability.

✅ Targets 100% carbon-free electricity statewide by 2050

✅ Prioritizes wind, solar, and efficiency before fossil fuels

✅ Faces utility cost, reliability, and legislative challenges

Gov. Tim Walz's plan for Minnesota to get 100 percent of its electricity from carbon-free sources by 2050, similar to California's 100% carbon-free mandate in scope, was criticized Tuesday at its first legislative hearing, with representatives from some of the state's smaller utilities saying they can't meet that goal.

Commerce Commissioner Steve Kelley told the House climate committee that the Democratic governor's plan is ambitious. But he said the state's generating system is "aging and at a critical juncture," with plants that produce 70 percent of the state's electricity coming up for potential retirement over the next two decades. He said it will ensure that utilities replace them with wind, solar and other innovative sources, and increased energy efficiency, before turning to fossil fuels.

"Utilities will simply need to demonstrate why clean energy would not work whenever they propose to replace or add new generating capacity," he said.

Walz's plan, announced last week, seeks to build on the success of a 2007 law that required Minnesota utilities to get at least 25 percent of their electricity from renewable sources by 2025. The state largely achieved that goal in 2017 thanks to the growth of wind and solar power, and the topic of climate change has only grown hotter, with some proposals like a fully renewable grid by 2030 pushing even faster timelines, hence the new goal for 2050.

But Joel Johnson, a lobbyist for the Minnkota Power Cooperative, testified that the governor's plan is "misguided and unrealistic" even with new technology to capture carbon dioxide emissions from power plants. Johnson added that even the big utilities that have set goals of going carbon-free by mid-century, such as Minneapolis-based Xcel Energy, acknowledge they don't know yet how they'll hit the net-zero electricity by mid-century target they have set.

Minnkota serves northwestern Minnesota and eastern North Dakota.

Tim Sullivan, president and CEO of the Wright-Hennepin Cooperative Electric Association in the Twin Cities area, said the plan is a "bad idea" for the 1.7 million state electric consumers served by cooperatives. He said Minnesota is a "minuscule contributor" to total global carbon emissions, even as the EU plans to double electricity use by 2050 to meet electrification demands.

"The bill would have a devastating impact on electric consumers," Sullivan said. "It represents, in our view, nothing short of a first-order threat to the safety and reliability of Minnesota's grid."

Isaac Orr is a policy fellow at the Minnesota-based conservative think tank, the Center for the American Experiment, which released a report critical of the plan Tuesday. Orr said all Minnesota households would face higher energy costs and it would harm energy-intensive industries such as mining, manufacturing and health care, while doing little to reduce global warming.

"This does not pass a proper cost-benefit analysis," he testified.

Environmental groups, including Conservation Minnesota and the Sierra Club, supported the proposal while acknowledging the challenges, noting that cleaning up electricity is critical to climate pledges in many jurisdictions.

"Our governor has called climate change an existential crisis," said Kevin Lee, director of the climate and energy program at the Minnesota Center for Environmental Advocacy. "This problem is the defining challenge of our time, and it can feel overwhelming."

Rep. Jean Wagenius, the committee chairwoman and Minneapolis Democrat who's held several hearings on the threats that climate change poses, said she expected to table the bill for further consideration after taking more testimony in the evening and would not hold a vote Tuesday.

While the bill has support in the Democratic-controlled House, it's not scheduled for action in the Republican-led Senate. Rep. Pat Garofalo, a Farmington Republican, quipped that it "has a worse chance of becoming law than me being named the starting quarterback for the Minnesota Vikings."

DOE Environmental Management Funding Boost seeks $7.25B to accelerate nuclear cleanup, upgrade Savannah River Site infrastructure, create jobs, and support small businesses, echoing ARRA 2009 results and expediting DOE EM waste remediation nationwide.

Key Points

A proposed $7.25B stimulus for DOE's EM to accelerate nuclear cleanup, modernize infrastructure, and create jobs.

✅ $7.25B one-time stimulus for DOE EM cleanup and infrastructure.

✅ Targets Savannah River Site; supports jobs and small businesses.

✅ Builds on ARRA 2009; accelerates nuclear waste remediation.

A bloc of local governments and nuclear industry, nuclear innovation efforts, labor and community groups are pressing Congress to provide a one-time multibillion-dollar boost to the U.S. Department of Energy Office of Environmental Management, the remediation-focused Savannah River Site landlord.

The organizations and officials -- including Citizens For Nuclear Technology Awareness Executive Director Jim Marra and Savannah River Site Community Reuse Organization President and CEO Rick McLeod -- sent a letter Friday to U.S. House and Senate leadership "strongly" supporting a $7.25 billion funding injection, even as ACORE challenges coal and nuclear subsidies in separate regulatory proceedings, arguing it "will help reignite the national economy," help revive small businesses and create thousands of new jobs despite the novel coronavirus crisis.

More than 30 million Americans have filed unemployment claims in the past two months, with additional clean energy job losses reported, too. Hundreds of thousands of claims have been filed in South Carolina since mid-March, compounding issues like unpaid utility bills in neighboring states.

The requested money could, too, speed Environmental Management's nuclear waste cleanup missions and be used to fix ailing infrastructure and strengthen energy security for rural communities nationwide -- some of which dates back to the Cold War -- at sites across the country. That's a "rare" opportunity, reads the letter, which prominently features the Energy Communities Alliance logo and its chairman's signature.

Similar funding programs, like what was done with the 2009 American Recovery and Reinvestment Act and recent clean energy funding initiatives, have been successful.

At the time, amid a staggering economic downturn nationwide, Environmental Management contractors "hired over 20,000 new workers," putting them "to work to reduce the overall cleanup complex footprint by 688 square miles while strengthening local economies," the Friday letter reads.

The Energy Department's cleanup office estimates the $6 billion investment years ago reduced its environmental liability by $13 billion, according to a 2012 report.

Such a leap forward, the coalition believes, is repeatable, a view reflected in current plans to revitalize coal communities with clean energy projects across the country.

"We are confident that DOE can successfully manage increased funding and leverage it for future economic development as it has in the past," the letter states. It continues: "We take pride in working together to support jobs and development of infrastructure and work that make our country stronger and assists us to recover from the impacts of COVID-19."

As of Monday afternoon, 8,942 cases of COVID-19, the disease caused by the novel coronavirus, have been logged in South Carolina. Aiken County is home to 155 of those cases.

OPG Pickering Nuclear Refurbishment extends four CANDU reactors to bolster Ontario clean energy, grid reliability, and decarbonization goals, leveraging Darlington lessons, mature supply chains, and AtkinsRealis OEM expertise for cost effective life extension.

Key Points

Modernizing four Pickering CANDU units to extend life, add clean power, and enhance Ontario grid reliability.

✅ Extends four 515 MW CANDU reactors by 30 years

✅ Supports clean, reliable baseload and decarbonization

✅ Leverages Darlington playbook and AtkinsRealis OEM supply chain

In a pivotal shift last month, Ontario Power Generation (OPG) revised its strategy for the Pickering Nuclear Power Station, scrapping plans to decommission its six remaining reactors. Instead, OPG has opted to modernize four reactors (Pickering B Units 5-8) starting in 2027, while Units 1 and 4 are slated for closure by the end of the current year.

This revision ensures the continued operation of the four 515 MW Canada Deuterium Uranium (CANDU) reactors—originally constructed in the 1970s and 1980s—extending their service life by at least 30 more years amid an extension request deadline for Pickering.

Todd Smith, Ontario's Energy Minister, underscored the significance of nuclear power in maintaining Ontario's status as a region with one of the cleanest and most reliable electricity grids globally. He emphasized the integral role of nuclear facilities, particularly the Pickering station, in the provincial energy strategy during the announcement supporting continued operations, which was made in the presence of union workers at the plant.

The Pickering station has demonstrated remarkable efficiency and reliability, notably achieving its second-highest output in 2023 and setting a record in 2022 for continuous operation. Extending the lifespan of nuclear plants like Pickering is deemed the most cost-effective method for sustaining low-carbon electricity, according to research conducted by the International Energy Agency (IEA) and the OECD Nuclear Energy Agency (NEA) across 243 plants in 24 countries.

The refurbishment project is poised to significantly boost Ontario's economy, projected to add CAN$19.4 billion to the GDP over 11 years and generate approximately 11,000 jobs annually. The Independent Electricity System Operator (IESO) has indicated that to meet the province's future electrification and decarbonization goals, as it faces a growing electricity supply gap, Ontario will need to double its nuclear capacity by 2050, requiring an addition of 17.8 GW of nuclear power.

Subo Sinnathamby, OPG's Senior Vice President of Nuclear Refurbishment, emphasized the necessity of nuclear energy in reducing reliance on natural gas. Sinnathamby, who is leading the refurbishment efforts at OPG's Darlington nuclear power station, where SMR plans are also underway, highlighted the positive impact of the Darlington and Bruce Power projects on the nuclear power supply chain and workforce.

The procurement strategy employed for Darlington, which involved placing orders early to ensure readiness among suppliers, is set to be replicated for the Pickering refurbishment. This approach aims to facilitate a seamless transition of skilled workers and resources from Darlington to Pickering refurbishment, leveraging a matured supply chain and experienced vendors.

AtkinsRealis, the original equipment manufacturer (OEM) for CANDU reactors, has a track record of successfully refurbishing CANDU plants worldwide. The CANDU reactor design, known for its refurbishment capabilities, allows for individual replacement of pressure tubes and access to fuel channels without decommissioning the reactor. Gary Rose, Executive Vice-President of Nuclear at AtkinsRealis, highlighted the economic benefits and environmental benefits of refurbishing reactors, stating it as a viable and swift solution to maximize fossil-free energy.

Looking forward, AtkinsRealis is exploring the potential for multiple refurbishments of CANDU reactors, which could extend their operational life beyond 100 years, addressing local energy needs and economic factors in the decision-making process. This innovative approach underscores the role of nuclear refurbishment in meeting global energy demands sustainably and economically.

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.
