REV Campus Challenge Receives $2 MILLION in Funding

U.S. power grid cyberattacks expose critical infrastructure to Russian hackers, DHS warns, targeting SCADA, smart grid sensors, and utilities; NERC CIP defenses, microgrids, and resilience planning aim to mitigate outages and supply chain disruptions.

Key Points

U.S. power grid cyberattacks target utility control systems, risking outages, disruption, requiring stronger defenses.

✅ Russian access to utilities and SCADA raises outage risk

✅ NERC CIP, DHS, and utilities expand cyber defenses

✅ Microgrids and renewables enhance resilience, islanding capability

The U.S. Department of Homeland Security has revealed that Russian government hackers accessed control rooms at hundreds of U.S. electrical utility companies, gaining far more access to the operations of many more companies than previously disclosed by federal officials.

Securing the electrical grid, upon which is built almost the entirety of modern society, is a monumental challenge. Several experts have explained aspects of the task, potential solutions and the risks of failure for The Conversation:

1. What’s at stake?

The scale of disruption would depend, in part, on how much damage the attackers wanted to do. But a major cyberattack on the electricity grid could send surges through the grid, much as solar storms have done.

Those events, explains Rochester Institute of Technology space weather scholar Roger Dube, cause power surges, damaging transmission equipment. One solar storm in March 1989, he writes, left “6 million people without power for nine hours … [and] destroyed a large transformer at a New Jersey nuclear plant. Even though a spare transformer was nearby, it still took six months to remove and replace the melted unit.”

More serious attacks, like larger solar storms, could knock out manufacturing plants that build replacement electrical equipment, gas pumps to fuel trucks to deliver the material and even “the machinery that extracts oil from the ground and refines it into usable fuel. … Even systems that seem non-technological, like public water supplies, would shut down: Their pumps and purification systems need electricity.”

In the most severe cases, with fuel-starved transportation stalled and other basic infrastructure not working, “[p]eople in developed countries would find themselves with no running water, no sewage systems, no refrigerated food, and no way to get any food or other necessities transported from far away. People in places with more basic economies would also be without needed supplies from afar.”

2. It wouldn’t be the first time

Russia has penetrated other countries’ electricity grids in the past, and used its access to do real damage. In the middle of winter 2015, for instance, a Russian cyberattack shut off the power to Ukraine’s capital in the middle of winter 2015.

Power grid scholar Michael McElfresh at Santa Clara University discusses what happened to cause hundreds of thousands of Ukrainians to lose power for several hours, and notes that U.S. utilities use software similar to their Ukrainian counterparts – and therefore share the same vulnerabilities.

3. Security work is ongoing

These threats aren’t new, write grid security experts Manimaran Govindarasu from Iowa State and Adam Hahn from Washington State University. There are a lot of people planning defenses, including the U.S. government, as substation attacks are growing across the country. And the “North American Electric Reliability Corporation, which oversees the grid in the U.S. and Canada, has rules … for how electric companies must protect the power grid both physically and electronically.” The group holds training exercises in which utility companies practice responding to attacks.

4. There are more vulnerabilities now

Grid researcher McElfresh also explains that the grid is increasingly complex, with with thousands of companies responsible for different aspects of generating, transmission, and delivery to customers. In addition, new technologies have led companies to incorporate more sensors and other “smart grid” technologies. He describes how that, as a recent power grid report card underscores, “has created many more access points for penetrating into the grid computer systems.”

5. It’s time to ramp up efforts

The depth of access and potential control over electrical systems means there has never been a better time than right now to step up grid security amid a renewed focus on protecting the grid among policymakers and utilities, writes public-utility researcher Theodore Kury at the University of Florida. He notes that many of those efforts may also help protect the grid from storm damage and other disasters.

6. A possible solution could be smaller grids

One protective effort was identified by electrical engineer Joshua Pearce at Michigan Technological University, who has studied ways to protect electricity supplies to U.S. military bases both within the country and abroad. He found that the Pentagon has already begun testing systems, as the military ramps up preparation for major grid hacks, that combine solar-panel arrays with large-capacity batteries. “The equipment is connected together – and to buildings it serves – in what is called a ‘microgrid,’ which is normally connected to the regular commercial power grid but can be disconnected and become self-sustaining when disaster strikes.”

He found that microgrid systems could make military bases more resilient in the face of cyberattacks, criminals or terrorists and natural disasters – and even help the military “generate all of its electricity from distributed renewable sources by 2025 … which would provide energy reliability and decrease costs, [and] largely eliminate a major group of very real threats to national security.”

EV-Driven Electricity Demand Growth will reshape utilities through electrification, EV adoption, grid modernization, and ratebasing of charging, as NREL forecasts rising terawatt-hours, CAGR increases, and demand-side flexibility to manage emissions and reliability.

Key Points

Growth in power consumption fueled by EV adoption and electrification, increasing utility sales and grid investment.

✅ NREL projects 20%-38% higher U.S. load by 2050

✅ Utilities see CAGR up to 1.6% and 80 TWh/year growth

✅ Demand-side flexibility and EV charging optimize grids

Utilities have struggled with flat demand for years, but analysis by the National Renewable Energy Laboratory predicts steady growth across the next three decades — largely driven by the adoption of electric vehicles, including models like the Tesla Model 3 that are reshaping expectations.

The study considers three scenarios, a reference case and medium- and high-adoption electrification predictions. All indicate demand growth, but in the medium and high scenarios for 2050, U.S. electricity consumption increases by 20% and 38%, respectively, compared to business as usual.

Utilities could go from stagnant demand to compound annual growth rates of 1.6%, which would amount to sustained absolute growth of 80 terawatt-hours per year.

"This unprecedented absolute growth in annual electricity consumption can significantly alter supply-side infrastructure development requirements," the report says, and could challenge state power grids in multiple regions.

NREL's Trieu Mai, principal investigator for the study, cautions that more research is needed to fully assess the drivers and impacts of electrification, "as well as the role and value of demand-side flexibility."

"Although we extensively and qualitatively discuss the potential drivers and barriers behind electric technology adoption in the report, much more work is needed to quantitatively understand these factors," Mai said in a statement.

However, utilities have largely bought into the dream.

"Electric vehicles are the biggest opportunity we see right now," Energy Impact Partners CEO Hans Kobler told Utility Dive. And the impact could go beyond just higher kilowattt-hour sales, particularly as electric truck fleets come online.

"When the transportation sector is fully electrified, it will result in around $6 trillion in investment," Kobler said. "Half of that is on the infrastructure side of the utility." And the industry can also benefit through ratebasing charging stations and managing the new demand.

One benefit that NREL's report points to is the possibility of "expanded value streams enabled by electric and/or grid-connected technologies," such as energy storage and mobile chargers that enhance flexibility.

"Many electric utilities are carefully watching the trend toward electrification, as it has the potential to increase sales and revenues that have stagnated or fallen over the past decade," the report said, highlighting potential benefits for all customers as adoption grows. "Beyond power system planning, other motivations to study electrification include its potential to impact energy security, emissions, and innovation in electrical end-use technologies and overall efficient system integration. The impacts of electrification could be far-reaching and have benefits and costs to various stakeholders."

Western Grid Integration aligns CAISO with a regional transmission operator under FERC oversight, boosting renewables, reliability, and cost savings while respecting state energy policy, emissions goals, and utility regulation across the West.

Key Points

Western Grid Integration lets CAISO operate under FERC to cut costs, boost reliability, and accelerate renewables.

✅ Lowers wholesale costs via wider dispatch and resource sharing

✅ Improves reliability with regional balancing and reserves

✅ Preserves state policy authority under FERC oversight

A strong and timely endorsement for western grid integration forcefully rebuts claims that moving from a balkanized system with 38 separate entities to a regional operation could introduce environmental problems, raise costs, or, as critics warn, export California’s energy policies to other western states, or open state energy and climate policies to challenge by federal regulators. In fact, Yale University’s Environmental Protection Clinic identifies numerous economic and environmental benefits from allowing the California Independent System Operator to become a regional grid operator.

The groundbreaking report comprehensively examines the policy and legal merits of allowing the California Independent System Operator (CAISO) to become a regional grid operator, open to any western utility or generator that wants to join, as similar market structure overhauls proceed in New England.

The Yale report identifies the increasing constraints that today’s fragmented western grid imposes on system-wide electricity costs and reliability, addresses the potential benefits of integration, and evaluates  potential legal risks for the states involved. California receives particular attention because its legislature is considering the first step in the grid integration process, which involves authorizing the CAISO to create a fully independent board, even as it examines revamping electricity rates to clean the grid (other western states are unlikely to approve joining an entity whose governance is determined solely by California’s governor and legislature, as is the case now).

Elements of the report

The analysis examined all of California’s key energy and climate policies, from its cap on carbon emissions to its renewable energy goals and its pollution standards for power plants, and concludes that none would face additional legal risks under a fully integrated western grid. The operator of such a grid would be regulated by an independent federal agency (the Federal Energy Regulatory Commission)—but so is the CAISO itself, now and since its inception, by virtue of its extended involvement in interstate electricity commerce throughout the West. 

And if empowered to serve the entire region, the CAISO would not interfere with the longstanding rights of California and other states to regulate their utilities’ investments or set energy and climate policies. The study points out that grid operators don’t set energy policies for the states they serve; they help those states minimize costs, enhance reliability in the wake of California blackouts across the state, and avoid unnecessary pollution.

And as to whether an integrated grid would help renewable energy or fossil fuels, the report finds that renewable resources would be the inevitable winners, thanks to their lower operating costs, although the most important winners would be western utility customers, through lower bills, expanded retail choice options, and improved reliability.

Call to action

The Yale report concludes with what amounts to a call to action for California’s legislators:

“In sum, enhanced Western grid integration in general, and the emergence of a regional system operator in particular, would not expose California’s clean energy policies to additional legal risks. Shifting to a regional grid operator would enable more efficient, affordable and reliable integration of renewable resources without increasing the legal risk to California’s clean energy policies.”

The authors of the analysis, from the Yale Law School and the Yale School of Forestry and Environmental Studies, are Juliana Brint, Josh Constanti, Franz Hochstrasser. and Lucy Kessler. They dedicated months to the project, consulted with a diverse group of reviewers, and made the trek from New Haven to Folsom, CA, to visit the California Independent System Operator and interview key staff members.

Russia Bitcoin Mining Ban highlights electricity deficits, grid stability concerns, and sustainability challenges, prompting stricter cryptocurrency regulation as mining operations in Siberia face shutdowns, relocations, and renewed focus on energy efficiency and resource allocation.

Key Points

Policy halting Bitcoin mining in key regions to ease electricity deficits, stabilize the grid, and prioritize energy.

✅ Targets high-load regions like Siberia facing electricity deficits

✅ Protects residential and industrial energy security, limits outages

✅ Prompts miner relocations, regulation, and potential renewables

In a significant shift in its stance on cryptocurrency, Russia has announced plans to ban Bitcoin mining in several key regions, primarily due to rising electricity deficits. This move highlights the ongoing tensions between energy management and the growing demand for cryptocurrency mining, which has sparked a robust debate about sustainability and resource allocation in the country.

Background on Bitcoin Mining in Russia

Russia has long been a major player in the global cryptocurrency landscape, particularly in Bitcoin mining. The country’s vast and diverse geography offers ample opportunities for mining, with several regions boasting low electricity costs and cooler climates that are conducive to operating the high-powered computers used for mining, similar to Iceland's mining boom in cold regions.

However, the boom in mining activities has put a strain on local electricity grids, as seen with BC Hydro suspensions in Canada, particularly as demand for energy continues to rise. This situation has become increasingly untenable, leading government officials to reconsider the viability of allowing large-scale mining operations.

Reasons for the Ban

The decision to ban Bitcoin mining in certain regions stems from a growing electricity deficit that has been exacerbated by both rising temperatures and increased energy consumption. Reports indicate that some regions are struggling to meet domestic energy needs, and jurisdictions like Manitoba's pause on crypto connections reflect similar grid concerns, particularly during peak consumption periods. Officials have expressed concern that continuing to support cryptocurrency mining could lead to blackouts and further strain on the electrical infrastructure.

Additionally, this ban is seen as a measure to redirect energy resources toward more critical sectors, including residential heating and industrial needs. By curbing Bitcoin mining, the government aims to prioritize the energy security of its citizens and maintain stability within its energy markets and the wider global electricity market dynamics.

Regional Impact

The regions targeted by the ban include areas that have seen a significant influx of mining operations, often attracted by the low costs of electricity. For instance, Siberia, known for its abundant natural resources and inexpensive power, has become a major center for miners. The ban is likely to have profound implications for local economies that have come to rely on the influx of investments from cryptocurrency companies.

Many miners are expected to be affected financially as they may have to halt operations or relocate to regions with more favorable regulations. This could lead to job losses and a decline in local business activities that have sprung up around the mining industry, such as hardware suppliers and tech services.

Broader Implications for Cryptocurrency in Russia

This ban reflects a broader trend within Russia’s approach to cryptocurrencies. While the government has been cautious about outright banning digital currencies, it has simultaneously sought to regulate the industry more stringently. Recent legislation has aimed to establish a legal framework for cryptocurrencies, focusing on taxation and oversight while navigating the balance between innovation and regulation.

As other countries around the world grapple with the implications of cryptocurrency mining, Russia’s decision adds to the narrative of the challenges associated with energy consumption in this sector. The international community is increasingly aware of the environmental impact of Bitcoin mining, which has come under fire for its significant energy use and carbon footprint.

Future of Mining in Russia

Looking ahead, the future of Bitcoin mining in Russia remains uncertain. While some regions may implement strict bans, others could potentially embrace a more regulated approach to mining, provided it aligns with energy availability and environmental considerations. The country’s vast landscape offers opportunities for innovative solutions, such as utilizing renewable energy sources, even as India's solar growth slows amid rising coal generation, to power mining operations.

As global attitudes toward cryptocurrency evolve, Russia will likely continue to adapt its policies in response to both domestic energy needs and international pressures, including Europe's shift away from Russian energy that influence policy choices. The balance between fostering a competitive cryptocurrency market and ensuring energy sustainability will be a key challenge for Russian policymakers moving forward.

Russia’s decision to ban Bitcoin mining in key regions marks a pivotal moment in the intersection of cryptocurrency and energy management. As the nation navigates its energy deficits, the implications for the mining industry and the broader cryptocurrency landscape will be significant. This move not only underscores the need for responsible energy consumption in the digital age but also reflects the complexities of integrating emerging technologies within existing frameworks of governance and infrastructure. As the situation unfolds, all eyes will be on how Russia balances innovation with sustainability in its approach to cryptocurrency.

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.
