Perhaps the most devastating thing that could happen in any developed country would be widespread catastrophic damage to its electric power grid. Nearly everything in an industrialized nation relies on electricity to function. Without it, normal water supplies, sewer systems, and communication services are cut off. Furthermore, things like food and transportation are quickly affected when power is down for extended periods.
A severe electromagnetic pulse (EMP) or geomagnetic disturbance (GMD) event could take the power grid down for months, and possibly even for years. An EMP is a very intense pulse of electromagnetic energy, typically caused by the detonation of a nuclear bomb or other high-energy explosive device. A GMD, meanwhile, can be caused when a solar eruption produces a coronal mass ejection (CME) that travels from the sun to the Earth. A direct hit by an extreme CME would cause widespread power blackouts disabling everything that uses electricity. Some experts have suggested that a major EMP or GMD hit could result in the death of up to 90% of the U.S. population.
What makes the event so devastating is that the U.S. power grid is not well-protected from such a strike, and the country is not prepared to recover quickly. Dr. William R. Forstchen, author of more than 40 books including the groundbreaking novel One Second After, which has been credited with raising national awareness to the potential threat posed by an EMP strike, explained the situation as a guest on The POWER Podcast. 
Forstchen noted that the U.S. power grid is vulnerable to such an event for a number of reasons. “The average component in our electrical grid is 40 to 50 years old. We are running our electricity on a 1970s, early-1980s industry. We’re not modernizing it,” he said. 
A few years ago, the federal government began to address the problem. “The Trump administration finally started taking action about six months before the election in 2020. They mandated DOD [the Department of Defense], DOE [the Department of Energy], all the different agencies to submit a comprehensive analysis of what needs to be done that would then follow by legislative action in the next Congress,” Forstchen explained. However, when Trump lost the election, President Biden immediately killed the initiative, he said.
Forstchen said relatively minor investments could vastly improve the situation. He suggested stockpiling key components is an important first step. “A large transformer for a major substation can cost several million dollars. From the time of ordering one until the big truck pulls up and we start to unload it is two or more years,” Forstchen said. Furthermore, he noted that most of the equipment and components that might be needed to repair the grid are now sourced from other countries, mainly China, which means the U.S. may not be able to get supplies, especially if the attack was initiated by one of those countries. “We should be building a strategic reserve of key electrical components,” he said.
Additionally, Forstchen said the U.S. should focus on a “lifeline to recovery.” He suggested hardening 10% of the grid could act as an insurance policy for the nation. “Let’s say the rest goes down, but we have those lifelines out there that can be used to start repairing things, bringing supplies, and communicate—big thing, communication and transportation,” said Forstchen. Risks could be substantially reduced with relatively minor investments. “I argue $20 to $30 billion a year would at least start ensuring some responsible response to this problem,” Forstchen said.

132. How an EMP or GMD Could Destroy the Power Grid and Create Chaos

While power outages are not uncommon in the U.S., widespread blackouts that last more than a couple of hours are pretty rare. However, this summer marks the 20th anniversary of one of the most significant blackouts in North American history. The incident didn’t just affect the U.S., but also major parts of Canada.
The blackout occurred on Aug. 14, 2003. The History Channel reports it began at 4:10 p.m. EDT, when 21 power plants shut down in just three minutes. Fifty million people were affected, including residents of New York City, Cleveland, and Detroit, as well as Toronto and Ottawa, Canada, among others. Although power companies were able to resume some service in as little as two hours, power remained off in other places for more than a day. The outage stopped trains and elevators, and disrupted everything from cellular telephone service to operations at hospitals and traffic at airports.
“It was close to quitting time in the afternoon, and given the warm weather in the middle of the summer and thunderstorm season, our system was holding up well. I was looking forward to actually leaving on time for a change,” Paul Toscarelli, senior director of Electric Transmission and Distribution (T&D) Operations for the Palisades Division with Public Service Electric and Gas (PSE&G), New Jersey’s largest utility, said as a guest on The POWER Podcast. Toscarelli was an engineer assigned to one of PSE&G’s regional distribution divisions at the time and was in the distribution dispatch office when the incident occurred. He recalled the event quite vividly.
“We were coming up around the second anniversary of 9/11, as I recollect, and just about everyone’s gut feel—instinctive feel—was this was another kind of terrorist attack,” Toscarelli said. “Looking back at it, it was very strange to recollect how relieved we were to find out it was just a widespread system outage of epic proportions.”
Of the 750,000 PSE&G customers that lost power that day, nearly three-quarters were back online within five hours and virtually all had service by noon the next day. PSE&G said diversification and design protections helped to contain the outage, and the company was safely able to reenergize the system circuit by circuit.
“The industry learned a lot about the electric system vulnerabilities,” said Toscarelli. Based on studies of the incident, the North American Electric Reliability Corporation (NERC) enhanced its standards in an effort to prevent future blackouts. 
Since the 2003 blackout, PSE&G has spent billions of dollars to further enhance the reliability and resiliency of its T&D systems with the aim of mitigating future outages. In fact, the company’s planned capital expenditures this year are the largest in the utility’s history—more than $3.5 billion.  
Among the projects PSE&G expects to complete in 2023 is a Newark Switch Rebuild Project. The Newark Switching Station is the heart of the company’s Newark T&D network. The $350 million project will modernize aging infrastructure that was put into service in 1957.
Another example is the $550 million Roseland-Pleasant Valley Project, which was completed in May and was one of PSE&G’s largest transmission projects to date. The 51-mile undertaking replaced transmission facilities that were, on average, about 90 years old.
“Infrastructure continually ages. It’s our job as the stewards of our system to monitor the usage of our equipment, inspect it, maintain it, and replace it where it’s deemed necessary, in a timely manner, and continuously repeat that process,” said Toscarelli. “We have an asset management model that involves risk assessment and risk scoring, and it lets us stay in the forefront of this.”

143. Power Grid Investments Improve Reliability and Make Blackouts Less Likely

It’s pretty easy to understand how the weather affects certain forms of power generation and infrastructure. Sunlight is obviously needed to generate solar power, wind is required to produce wind energy, and extreme storms of all kinds can wreak havoc on transmission and distribution lines, and other energy-related assets. Therefore, having accurate and constantly updated weather information is vital to power companies.
“First and foremost, utilities need to understand as best as possible the forecast of the environmental resources that are supplying these generation sources. It’s ultra-critical, because even small, slight changes in wind speed or solar radiation can have pretty substantial impacts as far as the capacity factor that a renewable generator is operating at,” Nic Wilson, director of product management for weather and climate risk with DTN, said as a guest on The POWER Podcast. 
Wilson highlighted some of the weather-related applications that utilities are integrating into their operations. “One of the focal points for DTN is working with utility emergency preparedness teams in order to help them better understand and forecast at-risk weather environmental hazards that are going to impact their overhead distribution operations, and understanding and communicating appropriately the outage impact risks,” he said.
“Another application is asset inspection,” said Wilson. “After a storm goes through, how does the utility prioritize where it’s going to do inspection along its lines for potential damage?” One way could be using DTN’s tools. Wilson suggested, for example, a company responsible for the operations and maintenance of wind farms could use DTN data to identify turbines that may have experienced blade damage during a weather event. With that insight, the company could proactively inspect for compromises to the fiberglass blades before the damage turned catastrophic.
Load forecasting is another important use case for DTN’s data. Many things must be considered to develop load forecasts including historical trends and current events. Wilson suggested temperature, precipitation, cloud cover, time of day, time of year, and more will affect not only the renewable energy production, but also demand for electricity. With accurate forecasts, power companies can plan appropriately to take advantage of any given situation. If they anticipate a surplus, units could be taken offline for scheduled maintenance, but if the supply is expected to be tight, they can issue orders to increase plant readiness.
“Then, there’s some emerging applications, such as capital planning, where utilities are trying to climate-adjust the age, and understand the performance and condition monitoring of their assets in order to prioritize resiliency investments,” Wilson said.
DTN’s products are constantly being refined too. Wilson said artificial intelligence and machine learning are behind many of the improvements. “We are consistently doing what we call retraining. So, as new data becomes available from the utility, whether that’s outage management system data, or condition monitoring information, or satellite- or LIDAR [light detection and ranging]-derived vegetation datasets, we’re incorporating that into our models and updating them as frequently as possible in order to ensure that our predictions are as representative of the current environment as possible,” he said.
Wilson said DTN is making some forays into climate modeling and trying to understand how different environmental factors of interest to utilities are going to evolve in not only the next three to six months on a seasonal basis, but also out to 30 years in the future. This is important information for power companies because they are often making investments with a 50-year time horizon in mind.

145. How Power Companies Benefit from Accurate Weather Forecasts

It’s no secret that power grids around the world need to expand to accommodate more renewable energy and the so-called “electrification of everything.” The latter, of course, refers to the growing trend of using electricity to power various sectors and applications that have traditionally relied on fossil fuels, such as natural gas or petroleum-based products. The electrification of everything includes the push toward electric vehicles; the transition from fossil fuel–based heating and cooling systems to electric alternatives, as well as the adoption of electric appliances; and the shift to more electric motors, furnaces, and other electric-powered equipment in manufacturing processes. Add to that the expected power needed to supply data centers and the growth of artificial intelligence-related computing, and current estimates of 50% load growth by 2050 could be vastly understated.
Yet, getting new transmission lines planned, approved, and constructed is a daunting task, often taking a decade or longer to complete. So, how can the world more quickly add transmission capacity to the system without investing enormous time and money in the process? The answer: grid enhancing technologies, or GETs.
“GETs are exciting to us because they are technologies that help us unlock quickly the additional headroom or additional capability of the grid to carry energy across the system,” Alexina Jackson, vice president of Strategic Development with AES Corp., said as a guest on The POWER Podcast. “This is something that is very important, because today, we are not making the fullest use of the electricity system as it’s built.”
The system is operated below its maximum capacity for very good reasons, specifically, to maintain reliability, but by implementing GETs, it can be operated closer to its true limits without risk of failure. “Once we have these technologies, such as dynamic line rating, which helps us visualize the dynamic and full headroom of the electrical grid, and then technologies like storage as transmission, advanced power flow control, topology optimization—they all allow us to operate the grid in its dynamic capability. By doing both these things—visualization and operation dynamically—we’re able to start making fuller use of that carrying capacity for energy, which will allow us to add additional energy more quickly, serve our customer needs more efficiently, and ultimately decarbonize faster,” Jackson said.

160. How Grid Enhancing Technologies Are Expanding Electric Power Transmission System Capabilities

The U.S. Energy Information Administration (EIA) reports SAIDI and SAIFI values in its Electric Power Annual report, which is regularly released in October each year. In the most recent report, the U.S. distribution system’s average SAIDI value including all events was 335.5 minutes per customer in 2022. If major event days were excluded, which is often a worthwhile exercise to get accurate long-term trends because hurricanes and severe winter storms, for example, can skew the numbers quite dramatically in a given year, the figure dropped to 125.7 minutes per customer. Notably, this the highest SAIDI value tallied in the past decade and it continued what has effectively been a steady year-over-year decline in performance from 2013 through 2022. (2017 saw a brief improvement over 2016, but every year before and since has been worse than the previous year during the timespan covered by the report.) For comparison, in 2013, the SAIDI value was 106.1 minutes per customer.
SAIFI values do not vary as noticeably as SAIDI, but still have been worsening. In 2022, the U.S. distribution system’s average SAIFI value including all events was 1.4 power interruptions per customer. With major events excluded, SAIFI was 1.1 interruptions per customer in the U.S. While this was not substantially worse than values reported in other years over the past decade (every year from 2013 onward has been 1.0, except for 2016 when the value was also 1.1), it seems to confirm that the system hasn’t been improving.
Yet, Mike Edmonds, Chief Operating Officer for S&C Electric Company, said several things can be done to improve the reliability and resiliency of the power distribution system. “The grid looks different depending on what state you’re in,” Edmonds said as a guest on The POWER Podcast. “We’ve got great experience with Florida Power & Light [FPL],” he said. “We’ve helped them create a resilient grid. So, that’s not only a grid that is reliable, but a grid that can actually weather the storms and all the challenges thrown at the grid.”
Notably, FPL reported in March that it had provided “the most reliable electric service in company history in 2023.” Over the past two decades, FPL said its customers have realized a remarkable 45% improvement in reliability. In NextEra Energy’s (the parent company of FPL) Sustainability Report 2023, the company reported FPL’s SAIDI was 47.1 and SAIFI was 0.85, confirming markedly better results than the U.S. averages noted earlier. Furthermore, FPL said this is the ninth time in the past 10 years that it achieved “its best-ever reliability rating.”
To better understand some of the innovative new equipment S&C Electric Company offers, Edmonds provided an example. “We have some technology that does something called ‘pulse finding,’ and what Florida Power & Light does, it just lets our equipment do what it does best. If there’s a problem, it’ll pulse to see if the problem is there or not on the grid, if it’s not, it reenergizes,” he said. “This technology is available to really change how the grid operates.”
Edmonds said S&C Electric Company invented the fuse 115 years ago, and he noted fuses have served the industry well since that time. However, today there is better technology available that doesn’t require a lineworker to respond to an outage to replace a fuse. “Let’s take fuses off the grid and have a fuseless grid, and have much more intelligent devices that can actually re-energize,” Edmonds decreed.
