How Synchrophasors are Bringing the Grid into the 21st Century

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.”

U.S. Power Grid Cybersecurity combats DHS-FBI flagged threats to energy infrastructure, with PJM Interconnection using ICS/SCADA segmentation, phishing defenses, incident response, and resilience exercises against Russia-linked attacks and pipeline intrusions.

Key Points

Strategies, controls, and training that protect U.S. electric infrastructure from cyber threats and disruptions.

✅ ICS/SCADA network segmentation and zero-trust architecture

✅ Employee phishing drills and incident response playbooks

✅ DOE-led grid exercises and threat intelligence sharing

The joint alert from the FBI and Department of Homeland Security last month warning that Russia was hacking into critical U.S. energy infrastructure, as outlined in six essential reads on Russian hacks from recent coverage, came as no surprise to the nation’s largest grid operator, PJM Interconnection.

“You will never stop people from trying to get into your systems. That isn’t even something we try to do.” said PJM Chief Information Officer, Tom O’Brien. “People will always try to get into your systems. The question is, what controls do you have to not allow them to penetrate? And how do you respond in the event they actually do get into your system?”

PJM is the regional transmission organization for 65 million people, covering 13 states, including Pennsylvania, and Washington D.C.

On a rainy day in early April, about 10 people were working inside PJM’s main control center, outside Philadelphia, closely monitoring floor-to-ceiling digital displays showing real-time information from the electric power sector throughout PJM’s territory in the mid-Atlantic and parts of the midwest, amid reports that hackers accessed control rooms at U.S. utilities.

Donnie Bielak, a reliability engineering manager, was overseeing things from his office, perched one floor up.

“This is a very large, orchestrated effort that goes unnoticed most of the time,” Bielak said. “That’s a good thing.”

But the industry certainly did take notice in late 2015 and early 2016, when hackers successfully disrupted power to the Ukrainian grid. The outages lasted a few hours and affected about 225,000 customers. It was the first publicly-known case of a cyber attack causing major disruptions to a power grid. It was widely blamed on Russia.

One of the many lessons of the Ukraine attacks was a reminder to people who work on critical infrastructure to keep an eye out for odd communications.

“A very large percentage of entry points to attacks are coming through emails,” O’Brien said. “That’s why PJM, as well as many others, have aggressive phishing campaigns. We’re training our employees.”

O’Brien doesn’t want to get into specifics about how PJM deals with cyber threats. But one common way to limit exposure is by having separate systems: For example, industrial controls in a power plant are not connected to corporate business networks, a separation underscored after breaches at U.S. power plants prompted reviews across the sector.

Since 2011, North American grid operators and government agencies have also done large, security exercises every two years. Thousands of people practice how they’d respond to a coordinated physical or cyber event, including rising substation attacks that highlight resilience gaps.

So far, nothing like that has happened in the U.S. It’s possible, but not likely, according to Robert M. Lee, a former military intelligence analyst, who runs the industrial cybersecurity firm Dragos.

“The more complex the system, the harder it is to have a scalable attack,” said Lee, who co-authored a report analyzing the Ukraine attacks. “If you wanted to take out a power generation station– that isn’t the most complex thing. Let’s say you cause an hour of outage. But now you want to cause two months of outages? That’s an exponential increase in effort required.”

For example, he said, it would very difficult for hackers to knock out power to the entire east coast for a long time. But briefly disrupting a major city is easier. That’s the sort of thing that keeps him up at night.

“I worry about an adversary getting into, maybe, Washington D.C.’s portion of the grid, taking down power for 30 minutes,” he said.

The Department of Energy is creating a new office focused on cybersecurity and emergency response, following the U.S. government’s condemnation of power grid hacking by Russia.

Deterrence may be one reason why there has not yet been a major attack on the U.S. grid, said John MacWilliams, a former senior DOE official who’s now a fellow at Columbia University’s Center on Global Energy Policy.

“That’s obviously an act of war,” he said. “We have the capability of responding either through cyber mechanisms or kinetic military.”

In the meantime, small-scale incidents keep happening.

This spring, another cyber attack targeted natural gas pipelines. Four companies shut down their computer systems, just in case, but they say no service was disrupted.

BC Hydro Time-of-Use Rates propose off-peak credits and peak surcharges, with 5 cent/kWh differentials, encouraging demand shifting, EV charging at night, and smart meter adoption, pending BC Utilities Commission review in an optional opt-in program.

Key Points

Optional pricing that credits 5 cents/kWh off-peak and adds 5 cents/kWh during 4-9 p.m. peak to encourage load shifting.

✅ Off-peak credit: 11 p.m.-7 a.m., 5 cents/kWh savings

✅ Peak surcharge: 4-9 p.m., additional 5 cents/kWh

✅ Opt-in only; BCUC review; suits EV charging and flexible loads

BC Hydro is looking to charge customers less for electricity during off peak hours and more during the busiest times of the day, reflecting holiday electricity demand as well.

The BC Utilities Commission is currently reviewing the application that if approved would see customers receive a credit of 5 cents per kilowatt hour for electricity used from 11 p.m. to 7 a.m.

Customers would be charged an additional 5 cents per kWh for electricity used during the on-peak period from 4 p.m. to 9 p.m., and in Ontario, there were no peak-rate cuts for self-isolating customers during early pandemic response.

There would be no credit or additional charge will be applied to usage during the off-peak period from 7 a.m. to 4 p.m. and 9 p.m. to 11 p.m.

“We know the way our customers are using power is changing and they want more options,” BC Hydro spokesperson Susie Rieder said.

“It is optional and we know it may not work for everyone.”

For example, if a customer has an electric vehicle it will be cheaper to plug the car in after 9 p.m., similar to Ontario's ultra-low overnight plan offerings, rather than immediately after returning home from a standard work day.

If approved, the time of use rates would only apply to customers who opt in to the program, whereas Ontario provided electricity relief during COVID-19.

During the pandemic, Ontario extended off-peak electricity rates to help households and small businesses.

The regulatory review process is expected to take about one year.

Other jurisdictions, including Ontario's ultra-low overnight pricing, currently offer off peak rates. One of the challenges is that consumers change in hopes of altering their behaviour, but in reality, end up paying more.

“The cheapest electrical grid system is one with consistent demand and the issue of course is our consumption is not flat,” energyrates.ca founder Joel MacDonald said.

“There is a 5 cent reduction in off peak times, there is a 5 cent increase in peak times, you would have to switch 50 per cent of your load.”

Northeast D.C. Power Outage highlights Pepco substation equipment failure, widespread service disruptions, grid reliability concerns, and restoration efforts, with calls for smart grid upgrades, better communication, and resilient infrastructure to protect residents, schools, and businesses.

Key Points

A Pepco substation failure caused outages, prompting restoration work and plans for smarter, resilient grid upgrades.

✅ Pepco cites substation equipment failure as root cause

✅ Crews prioritized rapid restoration and customer updates

✅ Calls grow for smart grid, resilience, and transparency

A recent power outage affecting Northeast Washington, D.C., has drawn attention to the vulnerabilities within the city’s energy infrastructure. The outage, caused by equipment failure at a Pepco substation, left thousands of residents in the dark and raised concerns about the reliability of electricity services in the area.

The Outage: What Happened?

On a typically busy weekday morning, Pepco, the local electric utility, reported significant power disruptions that affected several neighborhoods in Northeast D.C. Initial reports indicated that around 3,000 customers were without electricity due to issues at a nearby substation. The outages were widespread, impacting homes, schools, and businesses, and reflecting pandemic energy insecurity seen in many communities, creating a ripple effect of inconvenience and frustration.

Residents experienced not only the loss of power but also disruptions in daily activities. Many were unable to work from home, students faced challenges with remote learning, and businesses had to close or operate under limited conditions. The timing of the outage further exacerbated the situation, as it coincided with a period of increased demand for electricity, making efforts to prevent summer outages even more crucial for residents and businesses.

Community Response

In the wake of the outage, local community members and leaders quickly mobilized to assess the situation. Pepco crews were dispatched to restore power as swiftly as possible, but residents were left grappling with the immediate consequences. Local organizations and community leaders stepped in to provide support, especially as extreme heat can exacerbate electricity struggles for vulnerable households, offering resources such as food and shelter for those most affected.

Social media became a vital tool for residents to share information and updates about the situation. Many took to platforms like Twitter and Facebook to report their experiences and seek assistance. This grassroots communication helped keep the community informed and fostered a sense of solidarity during the disruption.

The Utility's Efforts

Pepco’s response involved not only restoring power but also addressing the underlying issues that led to the outage. The utility company communicated its commitment to investigating the cause of the equipment failure and ensuring that similar incidents would be less likely in the future. As part of this commitment, Pepco outlined plans for infrastructure upgrades, despite supply-chain constraints facing utilities nationwide, aimed at enhancing reliability across its service area.

Moreover, Pepco emphasized the importance of communication during outages. The company has been working to improve its notification systems, ensuring that customers receive timely updates about outages and restoration efforts. Enhanced communication can help mitigate the frustration experienced during such events and keep residents informed about when they can expect power to be restored.

Broader Implications for D.C.'s Energy Infrastructure

This recent outage has sparked a larger conversation about the resilience of Washington, D.C.’s energy infrastructure. As the city continues to grow and evolve, the demand for reliable electricity is more critical than ever. Frequent outages can undermine public confidence in utility providers and highlight the need for ongoing investment in infrastructure amid an aging U.S. grid that complicates renewable deployment and EV adoption across the country.

Experts suggest that to ensure a more reliable energy supply, utilities must embrace modernization efforts, including the integration of smart grid technology and renewable energy sources. These innovations can enhance the ability to manage electricity supply and demand, especially during unprecedented demand in the Eastern U.S. when heatwaves strain systems, reduce outages, and improve response times during emergencies.

The Path Forward

In response to the outage, community advocates are calling for greater transparency from Pepco and other utility companies. They emphasize the importance of holding utilities accountable for maintaining reliable service and communicating effectively with customers, while also promoting customer bill-reduction initiatives that help households manage costs. Public forums and discussions about energy policy can empower residents to voice their concerns and contribute to solutions.

As D.C. looks to the future, it is essential to prioritize investments in energy infrastructure that can withstand the demands of a growing population. Collaborations between local government, utility companies, and community organizations can drive initiatives aimed at enhancing resilience and ensuring that all residents have access to reliable electricity.

The recent power outage in Northeast D.C. serves as a reminder of the challenges facing urban energy infrastructure. While Pepco's efforts to restore power and improve communication are commendable, the incident highlights the need for long-term solutions to enhance reliability. By investing in modern technology and fostering community engagement, D.C. can work towards a more resilient energy future, ensuring that residents can count on their electricity service even in times of crisis.

Georgia Electricity Imports October 2017 surged as hydropower output fell and thermal power plants underperformed; ESCO balanced demand via low-cost imports, mainly from Azerbaijan, amid rising tariffs, kWh consumption growth, and a widening generation-consumption gap.

Key Points

They mark a record import surge due to costly local generation, lower hydropower, ESCO balancing costs, and rising demand.

✅ Imports rose 832% YoY to 157 mln kWh, mainly from Azerbaijan

✅ TPP output fell despite capacity; only low-tariff plants ran

✅ Balancing price 13.8 tetri/kWh signaled costly domestic PPAs

In October 2017, Georgian power plants generated 828 mln. KWh of electricity, marginally up (+0.79%) compared to September. Following the traditional seasonal pattern and amid European concerns over dispatchable power shortages affecting markets, the share of electricity produced by renewable sources declined to 71% of total generation (87% in September), while thermal power generation’s share increased, accounting for 29% of total generation (compared to 13% in September). When we compare last October’s total generation with the total generation of October 2016, however, we observe an 8.7% decrease in total generation (in October 2016, total generation was 907 mln. kWh). The overall decline in generation with respect to the previous year is due to a simultaneous decline in both thermal power and hydro power generation. 

Consumption of electricity on the local market in the same period was 949 mln. kWh (+7% compared to October 2016, and +3% with respect to September 2017), and reflected global trends such as India's electricity growth in recent years. The gap between consumption and generation increased to 121 mln. kWh (15% of the amount generated in October), up from 100 mln. kWh in September. Even more importantly, the situation was radically different with respect to the prior year, when generation exceeded consumption.

The import figure for October was by far the highest from the last 12 years (since ESCO was established), occurring as Ukraine electricity exports resumed regionally, highlighting wider cross-border dynamics. In October 2017, Georgia imported 157 mln. kWh of electricity (for 5.2 ¢/kWh – 13 tetri/kWh). This constituted an 832% increase compared to October 2016, and is about 50% larger than the second largest import figure (104.2 mln. kWh in October 2014). Most of the October 2017 imports (99.6%) came from Azerbaijan, with the remaining 0.04% coming from Russia.

The main question that comes to mind when observing these statistics is: why did Georgia import so much? One might argue that this is just the result of a bad year for hydropower generation and increased demand. This argument, however, is not fully convincing. While it is true that hydropower generation declined and demand increased, the country’s excess demand could have been easily satisfied by its existing thermal power plants, even as imported coal volumes rose in regional markets. Instead of increasing, however, the electricity coming from thermal power plants declined as well. Therefore, that cannot be the reason, and another must be found. The first that comes to mind is that importing electricity may have been cheaper than buying it from local TPPs, or from other generators selling electricity to ESCO under power purchase agreements (PPAs). We can test the first part of this hypothesis by comparing the average price of imported electricity to the price ceiling on the tariff that TPPs can charge for the electricity they sell. Looking at the trade statistics from Geostat, the average price for imported electricity in October 2017 remained stable with respect to the same month of the previous year, at 5.2 ¢ (13 tetri) per kWh. Only two thermal power plants (Gardabani and Mtkvari) had a price ceiling below 13 tetri per kWh. Observing the electricity balance of Georgia, we see that indeed more than 98% of the electricity generated by TPPs in October 2017 was generated by those two power plants.

What about other potential sources of electricity amid Central Asia's power shortages at the time? To answer this question, we can use the information derived from the weighted average price of balancing electricity. Why balancing electricity? Because it allows us to reconstruct the costs the market operator (ESCO) faced during the month of October to make sure demand and supply were balanced, and it allows us to gain an insight about the price of electricity sold through PPAs.

ESCO reports that the weighted average price of balancing electricity in October 2017 was 13.8 tetri/kWh, (25% higher than in October 2016, when it was below the average weighted cost of imports – 11 vs. 13 – and when the quantity of imported electricity was substantially smaller). Knowing that in October 2017, 61% of balancing electricity came from imports, while 39% came from hydropower and wind power plants selling electricity to ESCO under their PPAs, we can deduce that in this case, internal generation was (on average) also substantially more expensive than imports. Therefore, the high cost of internally generated electricity, rather than the technical impossibility of generating enough electricity to satisfy electricity demand, indeed appears to be one the main reasons why electricity imports spiked in October 2017.
