Synchrophasors deliver PMU-based, real-time monitoring for the smart grid, helping NYISO prevent blackouts, cut costs, and integrate renewables, with DOE-backed deployments boosting reliability, situational awareness, and data sharing across regional partners.

 

Key Points

Synchrophasors, or PMUs, are grid sensors that measure synced voltage, current, and frequency to enhance reliability.

✅ Real-time grid visibility and situational awareness

✅ Early fault detection to prevent cascading outages

✅ Supports renewable integration and lowers operating costs

 

Have you ever heard of a synchrophasor? It may sound like a word out of science fiction, but these mailbox-sized devices are already changing the electrical grid as we know it.

The grid was born over a century ago, at a time when our needs were simpler and our demand much lower. More complex needs are putting a heavy strain on the aging infrastructure, which is why we need to innovate and update our grid with investments in a smarter electricity infrastructure so it’s ready for the demands of today.

That’s where synchrophasors come in.

A synchrophasor is a sophisticated monitoring device that can measure the instantaneous voltage, current and frequency at specific locations on the grid. This gives operators a near-real-time picture of what is happening on the system, including insights into power grid vulnerabilities that allow them to make decisions to prevent power outages.

Just yesterday I attended the dedication of the New York Independent System Operator's smart grid control center, a $75 million project that will use these devices to locate grid problems at an early stage and share these data with their regional partners. This should mean fewer blackouts for the State of New York. I would like to congratulate NYISO for being a technology leader.

And not only will these synchrophasors help prevent outages, but they also save money. By providing more accurate and timely data on system limits, synchrophasors make the grid more reliable and efficient, thereby reducing planning and operations costs and addressing grid modernization affordability concerns for utilities.

The Department has worked with utilities across the country to increase the number of synchrophasors five-fold -- from less than 200 in 2009 to over 1,700 today. And this is just a part of our commitment to making a smarter, more resilient grid a reality, reinforced by grid improvement funding from DOE.

In September 2013, the US Department of Energy announced up to $9 million in funding to facilitate rapid response to unusual grid conditions. As a result, utilities will be able to better detect and head off potential blackouts, while improving day-to-day grid reliability and helping with the integration of solar into the grid and other clean renewable sources.

Electric Utilities Plot Bullish Course for EV Charging Infrastructure

EV Charging Infrastructure Incentives are expanding as utilities fund public chargers, Level 2 networks, DC fast charging, grid-managed off-peak programs, and equitable access across Ohio, New Jersey, and Florida to accelerate clean transportation.

 

Key Points

Utility-backed programs funding Level 2 and DC fast chargers, managing grid demand, and expanding EV equity.

✅ Incentives for Level 2 and DC fast public charging stations.

✅ Grid-friendly off-peak charging to balance demand.

✅ Equity targets place chargers in low-income communities.

 

Electric providers in Florida, Ohio and New Jersey recently announced plans to expand electric vehicle charging networks and infrastructure through various incentive programs that could add thousands of new public chargers in the next several years.

Elsewhere, utilities are advancing similar efforts, with Michigan EV programs proposing more than $20 million for charging infrastructure to accelerate adoption.

American Electric Power in Ohio will offer nearly $10 million in incentives toward the build out of 375 EV charging stations throughout the company's service territory, which largely includes Columbus.

Meanwhile, the Public Service Electric and Gas Company (PSE&G), an electric utility provider in New Jersey, has proposed a six-year plan to support the development of nearly 40,000 electric vehicle chargers across a wide range of customers and sectors, said Francis Sullivan, a spokesperson for PSE&G.

And Duke Energy in Florida is installing up to 530 EV charging stations across its service area, as part of its Park and Plug pilot program, which will be making the charging ports available in multifamily housing complexes, workplaces and other high traffic areas.

"We are bringing cleaner energy to Florida through 700 megawatts of new universal solar, and we are helping our customers to bring clean transportation to the state as well," Catherine Stempien, Duke Energy Florida president, said in a statement. "We are committed to providing smarter, cleaner energy alternatives for all our customers."

The project in Ohio is making incentive funding available to government organizations, multifamily housing developments and workplaces, covering from 50 percent to all of the costs. The plan, to be rolled out in the next four years, aims to incentivize the development of 300 level-two chargers and 75 "fast chargers" capable of charging a car's battery in minutes rather than hours.

"I think what's interesting about what we're seeing now in the industry is that electric vehicles and electric vehicle charging are expanding beyond California, and like other Pacific Coast states," said Scott Fisher, vice president of marketing at Greenlots, maker of car chargers and software. Greenlots has been selected as one of the companies to provide the chargers for the AEP project.

California has occupied the lion's share of the electric vehicle market, making up about 5 percent of the cars on the state's highways. The U.S. market sits at about 1.5 percent. However, indications show the EV boom may be set to take off as more models are being rolled out, and prices are making the electric cars more competitive with their gas-powered counterparts. The group Securing America's Future Energy (SAFE) announced the one-millionth electric vehicle is on course to be sold in the United States this month.

In a statement, Ben Prochazka, vice president of the Electrification Coalition, an EV advocacy group, called this "a major milestone and brings us one step closer to reducing our transportation system's dependence on oil. This is a direct result of the tireless efforts by communities and advocates throughout the 'EV ecosystem.'"

In New Jersey, PSE&G's efforts -- which are part of the company's proposed Clean Energy Future program -- will not only focus on building out the charging infrastructure, but structure car recharging to control charging and encourage residents to charge their cars during off-peak times.

"For now, with a modest number of charging stations in the market, it's not a huge problem. But over time, as you're putting in many thousands of these stations, what you want to make sure is that those stations are operating in sync with state power grids, where you don't have people all charging at the same time at like 5 p.m. on a hot summer day," said Fisher.

PSE&G also plans to offer incentives to encourage the development of level-two chargers and DC fast-chargers, as well as "provide grants and incentives for 100 electric school buses and EV charging infrastructure at school districts in PSE&G's service territory," said Sullivan.

"PSE&G will also help fund electrification projects at customer locations such as ports, airports and transit facilities," Sullivan added, via email.

Utilities and transportation planners are also keeping the concept of equity in mind -- to ensure EVs are adopted by more than just the Tesla owner -- and will also focus on placing infrastructure in low-income areas.

"Ten percent of the stations will be in low income areas, defined by census blocks," said Scott Blake, a communications consultant at AEP in Columbus.

Duke Energy also announced 10 percent of the chargers it is installing in Florida will be in "income-qualified communities," according to a company press release.

Energy Efficiency and Demand Response Can Nearly Level Southeast Electricity Demand for More than a Decade

Southeast Electricity Demand Forecast examines how energy efficiency, photovoltaics, electric vehicles, heat pumps, and demand response shape grid needs, stabilize load through 2030, shift peaks, and inform utility planning across the region.

 

Key Points

An outlook of load shaped by efficiency, solar, EVs, with demand response keeping usage steady through 2030.

✅ Stabilizes regional demand through 2030 under accelerated adoption

✅ Energy efficiency and demand response are primary levers

✅ EVs and heat pumps drive growth post 2030; shift winter peaks

 

Electricity markets in the Southeast are facing many changes on the customer side of the meter. In a new report released today, we look at how energy efficiency, photovoltaics (solar electricity), electric vehicles, heat pumps, and demand response (shifting loads from periods of high demand) might affect electricity needs in the Southeast.

We find that if all of these resources are pursued on an accelerated basis, electricity demand in the region can be stabilized until about 2030.

After that, demand will likely grow in the following decade because of increased market penetration of electric vehicles and heat pumps, but energy planners will have time to deal with this growth if these projections are borne out. We also find that energy efficiency and demand response can be vital for managing electricity supply and demand in the region and that these resources can help contain energy demand growth, reducing the impact of expensive new generation on consumer wallets.

 

National trends

This is the second ACEEE report looking at regional electricity demand. In 2016, we published a study on electricity consumption in New England, finding an even more pronounced effect. For New England, with even more aggressive pursuit of energy efficiency and these other resources, consumption was projected to decline through about 2030, before rebounding in the following decade.

These regional trends fit into a broader national pattern. In the United States, electricity consumption has been characterized by flat electricity demand for the past decade. Increased energy efficiency efforts have contributed to this lack of consumption growth, even as the US economy has grown since the Great Recession. Recently, the US Energy Information Administration (EIA – a branch of the US Department of Energy) released data on US electricity consumption in 2016, finding that 2016 consumption was 0.3% below 2015 consumption, and other analysts reported a 1% slide in 2023 on milder weather.

 

Five scenarios for the Southeast

ACEEE’s new study focuses on the Southeast because it is very different from New England, with warmer weather, more economic growth, and less-aggressive energy efficiency and distributed energy policies than the Northeast. For the Southeast, we examined five scenarios: a business-as-usual scenario; two alternative scenarios with progressively higher levels of energy efficiency, photovoltaics informed by a solar strategy for the South that is emerging regionally, electric vehicles, heat pumps, and demand response; and two scenarios combining high numbers of electric vehicles and heat pumps with more modest levels of the other resources. This figure presents electricity demand for each of these scenarios:

Over the 2016-2040 period, we project that average annual growth will range from 0.1% to 1.0%, depending on the scenario, much slower than historic growth in the region. Energy efficiency is generally the biggest contributor to changes in projected 2040 electricity consumption relative to the business-as-usual scenario, as shown in the figure below, which presents our accelerated scenario that is based on levels of energy efficiency and other resources now targeted by leading states and utilities in the Southeast.

To date, Entergy Arkansas has achieved the annual efficiency savings as a percent of sales shown in the accelerated scenario and Progress Energy (a division of Duke Energy) has nearly achieved those savings in both North and South Carolina. Sixteen states outside the Southeast have also achieved these savings statewide.

The efficiency savings shown in the aggressive scenario have been proposed by the Arkansas PSC. This level of savings has already been achieved by Arizona as well as six other states. Likewise, the demand response savings we model have been achieved by more than 10 utilities, including four in the Southeast. The levels of photovoltaic, electric vehicle, and heat pump penetration are more speculative and are subject to significant uncertainty.

We also examined trends in summer and winter peak demand. Most utilities in the Southeast have historically had peak demand in the summer, often seeing heatwave-driven surges that stress operations across the Eastern U.S., but our analysis shows that winter peaks will be more likely in the region as photovoltaics and demand response reduce summer peaks and heat pumps increase winter peaks.

 

Why it’s vital to plan broadly

Our analysis illustrates the importance of incorporating energy efficiency, demand response, and photovoltaics into utility planning forecasts as utility trends to watch continue to evolve. Failing to include these resources leads to much higher forecasts, resulting in excess utility system investments, unnecessarily increasing customer electricity rates. Our analysis also illustrates the importance of including electric vehicles and heat pumps in long-term forecasts. While these technologies will have moderate impacts over the next 10 years, they could become increasingly important in the long run.

We are entering a dynamic period of substantial uncertainty for long-term electricity sales and system peaks, highlighted by COVID-19 demand shifts that upended typical patterns. We need to carefully observe and analyze developments in energy efficiency, photovoltaics, electric vehicles, heat pumps, and demand response over the next few years. As these technologies advance, we can create policies to reduce energy bills, system costs, and harmful emissions, drawing on grid reliability strategies tested in Texas, while growing the Southeast’s economy. Resource planners should be sure to incorporate these emerging trends and policies into their long-term forecasts and planning.

French Price-Fixing Probe: Schneider, Legrand, Rexel, and Sonepar Fined

French Antitrust Fines for Electrical Cartel expose price fixing by Schneider Electric, Legrand, Rexel, and Sonepar, after a Competition Authority probe into electrical distribution, collusion, and compliance breaches impacting market competition and customers.

 

Key Points

Penalties on Schneider Electric, Legrand, Rexel, and Sonepar for electrical price fixing, upholding competition law.

✅ Competition Authority fined four major suppliers.

✅ Collusion raised prices across construction and industry.

✅ Firms bolster compliance programs and training.

 

In a significant crackdown on corporate malfeasance, French authorities have imposed hefty fines on four major electrical equipment companies—Schneider Electric, Legrand, Rexel, and Sonepar—after concluding a price-fixing investigation. The total fines amount to approximately €500 million, underscoring the seriousness with which regulators are addressing anti-competitive practices in the electrical distribution sector, even as France advances a new electricity pricing scheme to address EU concerns.

Background of the Investigation

The probe, initiated by France’s Competition Authority, sought to uncover collusion among these leading firms regarding the pricing of electrical equipment and services between 2005 and 2012. This investigation is part of a broader initiative to promote fair competition within the market, as Europe prepares to revamp its electricity market to bolster transparency, ensuring that consumers and businesses alike benefit from competitive pricing and innovative products.

The inquiry revealed that these companies had engaged in illicit agreements to fix prices and coordinate their market strategies, limiting competition in a sector critical to both the economy and infrastructure. The findings indicated that the collusion not only stifled competition but also led to inflated prices for customers, illustrating why rolling back electricity prices is often more complex than it appears for customers across various sectors, from construction to manufacturing.

The Fines Imposed

Following the conclusion of the investigation, the fines levied against the companies were substantial. Schneider Electric faced the largest penalty, receiving a fine of €220 million, while Legrand was fined €150 million. Rexel and Sonepar were each fined €70 million and €50 million, respectively. These financial penalties serve as a deterrent to other companies that might consider engaging in similar practices, reinforcing the message that anti-competitive behavior will not be tolerated.

The fines are particularly significant given the size and influence of these companies within the electrical equipment market. Their combined revenues amount to billions of euros annually, making the repercussions of their actions far-reaching. As major players in the industry, their pricing strategies have a direct impact on numerous sectors, from residential construction to large-scale industrial projects.

Industry Reactions

The response from the affected companies has varied. Schneider Electric expressed its commitment to compliance and transparency, acknowledging the importance of adhering to competition laws, amid ongoing EU electricity reform debates that influence market expectations.

Legrand also emphasized its commitment to fair competition, noting that it has taken steps to enhance its compliance framework in response to the investigation. Rexel and Sonepar similarly reaffirmed their dedication to ethical business practices and their intention to cooperate with regulators in the future.

Industry experts have pointed out that these fines, while significant, may not be enough to deter large corporations from engaging in similar behavior unless accompanied by a broader cultural shift within the industry. There is a growing call for enhanced oversight and stricter penalties to ensure that companies prioritize ethical conduct over short-term profits.

Implications for the Market

The fines imposed on Schneider, Legrand, Rexel, and Sonepar could have broader implications for the electrical equipment market and beyond. They signal to other companies within the sector that regulatory bodies are vigilant, even as nine EU countries oppose electricity market reforms proposed as fixes for price spikes, and willing to take decisive action against anti-competitive practices. This could foster a more competitive environment, ultimately benefiting consumers through better prices and enhanced product offerings.

Moreover, the case highlights the importance of regulatory bodies in maintaining fair market conditions. As industries evolve, ongoing vigilance from competition authorities will be necessary to prevent similar instances of collusion and ensure that markets remain competitive and innovative, as seen when New York opened a formal review of retail energy markets.

The recent fines imposed on Schneider Electric, Legrand, Rexel, and Sonepar mark a significant moment in France's ongoing battle against corporate price-fixing and anti-competitive practices, occurring as the government and EDF reached a deal on electricity prices to balance market pressures. With total penalties exceeding €500 million, the investigation underscores the commitment of French authorities to uphold market integrity and protect consumer interests.

As the industry reflects on these developments, it remains crucial for companies to prioritize compliance and ethical business practices. The ultimate goal is to create an environment where competition thrives, innovation flourishes, and consumers benefit from fair pricing. This case serves as a reminder that transparency and accountability are vital in maintaining the health of any market, particularly one as essential as the electrical equipment sector.

Russian hackers had 'hundreds of victims' as they infiltrated U.S. power grid

Russian cyberattacks on U.S. power grid exposed DHS warnings: Dragonfly/Energetic Bear breached control rooms, ICS networks, and could trigger blackouts via switch manipulation, phishing, and malware, threatening critical infrastructure and utility operations nationwide.

 

Key Points

State-backed breaches of utility ICS and control rooms enabled potential switch manipulation and blackouts.

✅ DHS: Dragonfly/Energetic Bear breached utility networks

✅ Access reached control rooms and ICS for switch control

✅ Ongoing campaign via phishing, malware, lateral movement

 

Russian hackers for a state-sponsored organization invaded hundreds of control rooms of U.S. electric utilities that could have led to blackouts, a new report says.

The group, known as Dragonfly or Energetic Bear, infiltrated networks of U.S. utilities as part of an effort that is likely ongoing, Department of Homeland Security officials told the Wall Street Journal.

Jonathan Home, chief of industrial-control-system analysis for DHS, said the hackers “got to the point where they could have thrown switches” and upset power flows.

Although the agency did not disclose which companies were impacted, the officials at a briefing Monday said that there were “hundreds of victims” including breaches at power plants across the U.S., and that some companies may not be aware that hackers infiltrated their networks yet.

According to experts, Russia has been preparing for such attacks for some time now, prompting a renewed focus on protecting the grid among utilities and policymakers.

“They’ve been intruding into our networks and are positioning themselves for a limited or widespread attack,” said former Deputy Assistant Defense Secretary Michael Carpenter, now senior director at the Penn Biden Center at the University of Pennsylvania, per the Wall Street Journal. “They are waging a covert war on the West.”

Earlier this year, the Trump administration claimed Russia had staged a power grid hacking campaign against the U.S. energy grid and other U.S. infrastructure.

The report comes after President Trump told reporters last week during a joint press conference in Helsinki alongside Russian President Vladimir Putin that he had no reason not to believe the Russian leader's assurances to him that the Kremlin was not to blame for interference in the election.

Trump later admitted that he misspoke when he said he didn’t “see any reason why” Russia would have meddled in the 2016 election, and said he believes the U.S. intelligence community assessment that found that the Russian government did interfere in the electoral process.

Tesla’s Powerwall as the beating heart of your home

GMP Tesla Powerwall Program replaces utility meters with smart battery storage, enabling virtual power plant services, demand response, and resilient homes, integrating solar readiness, EV charging support, and smart grid controls across Vermont households.

 

Key Points

Green Mountain Power uses Tesla Powerwalls as smart meters, creating a VPP for demand response and home backup.

✅ $30 monthly for 10 years or $3,000 upfront for two units

✅ Utility controls batteries for peak shaving and demand response

✅ Enables backup power, solar readiness, and EV charging support

 

There are more than 100 million single-family homes in the United States of America. If each of these homes were to have two 13.5 kWh Tesla Powerwalls, that would total 2.7 Terawatt-hours worth of electricity stored. Prior research has suggested that this volume of energy storage could get us halfway to the 5.4 TWh of storage needed to let the nation get 80% of its electricity from solar and wind, as states like California increasingly turn to grid batteries to support the transition.

Vermont utility Green Mountain Power (GMP) seeks to remove standard electric utility metering hardware and replace it with the equipment inside of a Tesla Powerwall, as part of a broader digital grid evolution underway. Mary Powell, President and CEO of Green Mountain Power, says, “We have a vision of a battery system in every single home” and they’ve got a patent pending software solution to make it happen.

The Resilient Home program will install two standard Tesla Powerwalls each in 250 homes in GMP’s service area. The homeowner will pay either $30 a month for ten years ($3,600), or $3,000 up front. At the end of the ten year period, payments end, but the unit can stay in the home for an additional five years – or as long as it has a usable life.

A single Powerwall costs approximately $6,800, making this a major discount.

GMP notes that the home must have reliable internet access to allow GMP and Tesla to communicate with the Powerwall. GMP will control the functions of the Powerwall, effectively operating a virtual power plant across participating homes, expanding the scope of programs like those that saved the state’s ratepayers more than $500,000 during peak demand events last year. The utility specifically notes that customers agree to share stored energy with GMP on several peak demand days each year.

The hardware can be designed to interact with current backup generators during power outages, or emerging fuel cell solutions that maintain battery charge longer during extended outages, however, the units will not charge from the generator. As noted the utility will be making use of the hardware during normal operating times, however, during a power outage the private home owner will be able to use the electricity to back up both their house and top off their car.

The utility told pv magazine USA that the Powerwalls are standard from the factory, with GMP’s patent pending software solution being the special sauce (has a hint of recent UL certifications). GMP said the program will also get home owners “adoption ready” for solar power, including microgrid energy storage markets, and other smart devices.

Sonnen’s ecoLinx is already directly interacting with a home’s electrical panel (literally throwing wifi enabled circuit breakers). Now with Tesla Powerwalls being used to replace utility meters, we see one further layer of integration that will lead to design changes that will drive residential solar toward $1/W. Electric utilities are also experimenting with controlling module level electronics and smart solar inverters in 100% residential penetration situations. And of course, considering that California is requiring solar – and probably storage in the future – in all new homes, we should expect to see further experimentation in this model. Off grid solar inverter manufacturers already include electric panels with their offerings.

If we add in the electric car, and have vehicle-to-grid abilities, we start to see a very strong amount of electricity generation and energy storage, helping to keep the lights on during grid stress, potentially happening in more than 100 million residential power plants. Resilient homes indeed.

Hydro One wants to spend another $6-million to redesign bills

Hydro One Bill Redesign Spending sparks debate over Ontario Energy Board regulation, rate applications, privatization, and digital billing upgrades, as surveys cite confusing invoices under the Fair Hydro Plan for residential, commercial, and industrial customers.

 

Key Points

$15M project to simplify Hydro One bills, upgrade systems, and improve digital billing for commercial customers.

✅ $9M spent; $6M proposed for C&I and large-account changes.

✅ OEB to rule amid rate application and privatization scrutiny.

✅ Survey: 40% of customers struggled to understand bills.

 

Ontario's largest and recently privatized electricity utility has spent $9-million to redesign bills and is proposing to spend an additional $6-million on the project.

Hydro One has come under fire for spending since the Liberal government sold more than half of the company, notably for its CEO's $4.5-million pay.

Now, the NDP is raising concerns with the $15-million bill redesign expense contained in a rate application from the formerly public utility.

"I don't think the problem we face is a bill that people can't understand, I think the problem is rates that are too high," said energy critic Peter Tabuns. "Fifteen million dollars seems awfully expensive to me."

But Hydro One says a 2016 survey of its customers indicated about 40 per cent had trouble understanding their bills.

Ferio Pugliese, the company's executive vice-president of customer care and corporate affairs, said the redesign was aimed at giving customers a simpler bill.

"The new format is a format that when tested and put in front of our customers has been designed to give customers the four or five salient items they want to see on their bill," he said.

About $9-million has already gone into redesigning bills, mostly for residential customers, Pugliese said. Cosmetic changes to bills account for about 25 per cent of the cost, with the rest of the money going toward updating information systems and improving digital billing platforms, he said.

The additional $6-million Hydro One is looking to spend would go toward bill changes mostly for its commercial, industrial and large distribution account customers.

Energy Minister Glenn Thibeault noted in a statement that the Ontario Energy Board has yet to decide on the expense, but he suggested he sees the bill redesign as necessary alongside legislation to lower electricity rates introduced by the province.

"With Ontarians wanting clearer bills that are easier to understand, Hydro One's bill redesign project is a necessary improvement that will help customers," he wrote.

"Reductions from the Fair Hydro Plan (the government's 25 per cent cut to bills last year) are important information for both households and businesses, and it's our job to provide clear, helpful answers whenever possible."

The OEB recently ordered Hydro One to lower a rate increase it had been seeking for this year to 0.2 per cent down from 4.8 per cent.

The regulator also rejected a Hydro One proposal to give shareholders all of the tax savings generated by the IPO in 2015 when the Liberal government first began partially privatizing the utility. The OEB instead mandated shareholders receive 62 per cent of the savings while ratepayers receive the remaining 38 per cent.
