New Rules for a Future Puerto Rico Microgrid Landscape

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.

ICT Electricity Demand is surging as data centers, 5G, IoT, and server farms expand, straining grids, boosting carbon emissions, and challenging climate targets unless efficiency, renewable energy, and smarter cooling dramatically improve.

Key Points

ICT electricity demand is power used by networks, devices, and data centers across the global communications sector.

✅ Projected to reach up to 20 percent of global electricity by 2025

✅ Driven by data centers, 5G traffic, IoT, and high-res streaming

✅ Mitigation: efficiency, renewable PPAs, advanced cooling, workload shifts

The communications industry could use 20% of all the world’s electricity by 2025, hampering attempts to meet climate change targets, even as countries like New Zealand's electrification plans seek broader decarbonization, and straining grids as demand by power-hungry server farms storing digital data from billions of smartphones, tablets and internet-connected devices grows exponentially.

The industry has long argued that it can considerably reduce carbon emissions by increasing efficiency and reducing waste, but academics are challenging industry assumptions. A new paper, due to be published by US researchers later this month, will forecast that information and communications technology could create up to 3.5% of global emissions by 2020 – surpassing aviation and shipping – and up to 14% 2040, around the same proportion as the US today.

Global computing power demand from internet-connected devices, high resolution video streaming, emails, surveillance cameras and a new generation of smart TVs is increasing 20% a year, consuming roughly 3-5% of the world’s electricity in 2015, says Swedish researcher Anders Andrae.

In an update o a 2016 peer-reviewed study, Andrae found that without dramatic increases in efficiency, the ICT industry could use 20% of all electricity and emit up to 5.5% of the world’s carbon emissions by 2025. This would be more than any country, except China, India and the USA, where China's data center electricity use is drawing scrutiny.

He expects industry power demand to increase from 200-300 terawatt hours (TWh) of electricity a year now, to 1,200 or even 3,000TWh by 2025. Data centres on their own could produce 1.9 gigatonnes (Gt) (or 3.2% of the global total) of carbon emissions, he says.

“The situation is alarming,” said Andrae, who works for the Chinese communications technology firm Huawei. “We have a tsunami of data approaching. Everything which can be is being digitalised. It is a perfect storm. 5G [the fifth generation of mobile technology] is coming, IP [internet protocol] traffic is much higher than estimated, and all cars and machines, robots and artificial intelligence are being digitalised, producing huge amounts of data which is stored in data centres.”

US researchers expect power consumption to triple in the next five years as one billion more people come online in developing countries, and the “internet of things” (IoT), driverless cars, robots, video surveillance and artificial intelligence grows exponentially in rich countries.

The industry has encouraged the idea that the digital transformation of economies and large-scale energy efficiencies will slash global emissions by 20% or more, but the scale and speed of the revolution has been a surprise.

Global internet traffic will increase nearly threefold in the next five years says the latest Cisco Visual Networking Index, a leading industry tracker of internet use.

“More than one billion new internet users are expected, growing from three billion in 2015 to 4.1bn by 2020. Over the next five years global IP networks will support up to 10bn new devices and connections, increasing from 16.3bn in 2015 to 26bn by 2020,” says Cisco.

A 2016 Berkeley laboratory report for the US government estimated the country’s data centres, which held about 350m terabytes of data in 2015, could together need over 100TWh of electricity a year by 2020. This is the equivalent of about 10 large nuclear power stations.

Data centre capacity is also rocketing in Europe, where the EU's plan to double electricity use by 2050 could compound demand, and Asia with London, Frankfurt, Paris and Amsterdam expected to add nearly 200MW of consumption in 2017, or the power equivalent of a medium size power station.

“We are seeing massive growth of data centres in all regions. Trends that started in the US are now standard in Europe. Asia is taking off massively,” says Mitual Patel, head of EMEA data centre research at global investment firm CBRE.

“The volume of data being handled by such centres is growing at unprecedented rates. They are seen as a key element in the next stage of growth for the ICT industry”, says Peter Corcoran, a researcher at the university of Ireland, Galway.

Using renewable energy sounds good but no one else benefits from what will be generated, and it skews national attempts to reduce emissions

Ireland, which with Denmark is becoming a data base for the world’s biggest tech companies, has 350MW connected to data centres but this is expected to triple to over 1,000MW, or the equivalent of a nuclear power station size plant, in the next five years.

Permission has been given for a further 550MW to be connected and 750MW more is in the pipeline, says Eirgrid, the country’s main grid operator.

“If all enquiries connect, the data centre load could account for 20% of Ireland’s peak demand,” says Eirgrid in its All-Island Generation Capacity Statement 2017-2026  report.

The data will be stored in vast new one million square feet or larger “hyper-scale” server farms, which companies are now building. The scale of these farms is huge; a single $1bn Apple data centre planned for Athenry in Co Galway, expects to eventually use 300MW of electricity, or over 8% of the national capacity and more than the daily entire usage of Dublin. It will require 144 large diesel generators as back up for when the wind does not blow.

Pressed by Greenpeace and other environment groups, large tech companies with a public face , including Google, Facebook, Apple, Intel and Amazon, have promised to use renewable energy to power data centres. In most cases they are buying it off grid but some are planning to build solar and wind farms close to their centres.

Greenpeace IT analyst Gary Cook says only about 20% of the electricity used in the world’s data centres is so far renewable, with 80% of the power still coming from fossil fuels.

“The good news is that some companies have certainly embraced their responsibility, and are moving quite aggressively to meet their rapid growth with renewable energy. Others are just growing aggressively,” he says.

Architect David Hughes, who has challenged Apple’s new centre in Ireland, says the government should not be taken in by the promises.

“Using renewable energy sounds good but no one else benefits from what will be generated, and it skews national attempts to reduce emissions. Data centres … have eaten into any progress we made to achieving Ireland’s 40% carbon emissions reduction target. They are just adding to demand and reducing our percentage. They are getting a free ride at the Irish citizens’ expense,” says Hughes.

Eirgrid estimates indicate that by 2025, one in every 3kWh generated in Ireland could be going to a data centre, he added. “We have sleepwalked our way into a 10% increase in electricity consumption.”

Fossil fuel plants may have to be kept open longer to power other parts of the country, and manage issues like SF6 use in electrical equipment, and the costs will fall on the consumer, he says. “We will have to upgrade our grid and build more power generation both wind and backup generation for when the wind isn’t there and this all goes onto people’s bills.”

Under a best case scenario, says Andrae, there will be massive continuous improvements of power saving, as the global energy transition gathers pace, renewable energy will become the norm and the explosive growth in demand for data will slow.

But equally, he says, demand could continue to rise dramatically if the industry keeps growing at 20% a year, driverless cars each with dozens of embedded sensors, and cypto-currencies like Bitcoin which need vast amounts of computer power become mainstream.

“There is a real risk that it all gets out of control. Policy makers need to keep a close eye on this,” says Andrae.

Canada Electricity Grid Decarbonization advances net-zero goals by expanding renewable energy (wind, solar, hydro), boosting grid reliability with battery storage, and aligning policy, efficiency, and investment to cut emissions and strengthen energy security.

Key Points

Canada's shift to low-carbon power using renewables and storage to cut emissions and improve grid reliability.

✅ Invest in wind, solar, hydro, and transmission upgrades

✅ Deploy battery storage to balance intermittent generation

✅ Support just transition, jobs, and energy efficiency

As Canada moves towards a more sustainable future, decarbonizing its electricity grid has emerged as a pivotal goal. The transition aims to reduce greenhouse gas emissions, promote renewable energy sources, and ultimately support global climate targets, with cleaning up Canada's electricity widely viewed as critical to meeting those pledges. However, the implications of this transition are multifaceted, impacting the economy, energy reliability, and the lives of Canadians.

Understanding Decarbonization

Decarbonization refers to the process of reducing carbon emissions produced from various sources, primarily fossil fuels. In Canada, the electricity grid is heavily reliant on natural gas, coal, and oil, which contribute significantly to carbon emissions. The Canadian government has committed to achieving net-zero by 2050 through federal and provincial collaboration, with the electricity sector playing a crucial role in this initiative. The strategy includes increasing the use of renewable energy sources such as wind, solar, and hydroelectric power.

Economic Considerations

Transitioning to a decarbonized electricity grid presents both challenges and opportunities for Canada’s economy. On one hand, the initial costs of investing in renewable energy infrastructure can be substantial. This includes not only the construction of renewable energy plants but also the necessary upgrades to the grid to accommodate new technologies. According to the Fraser Institute analysis, these investments could lead to increased electricity prices, impacting consumers and businesses alike.

However, the shift to a decarbonized grid can also stimulate economic growth. The renewable energy sector is a rapidly growing industry that, as Canada’s race to net-zero accelerates, promises job creation in manufacturing, installation, and maintenance of renewable technologies. Moreover, as technological advancements reduce the cost of renewable energy, the long-term savings on fuel costs can benefit both consumers and businesses. The challenge lies in balancing these economic factors to ensure a smooth transition.

Reliability and Energy Security

A significant concern regarding the decarbonization of the electricity grid is maintaining reliability and energy security, especially as an IEA report indicates Canada will need substantially more electricity to achieve net-zero goals, requiring careful system planning.

To address this challenge, the implementation of energy storage solutions and grid enhancements will be essential. Advances in battery technology and energy storage systems can help manage supply and demand effectively, ensuring that energy remains available even during periods of low renewable output. Additionally, integrating a diverse mix of energy sources, including hydroelectric power, can enhance the reliability of the grid.

Social Impacts

The decarbonization process also carries significant social implications. Communities that currently depend on fossil fuel industries may face economic challenges as the transition progresses, and the Canadian Gas Association has warned of potential economy-wide costs for switching to electricity, underscoring the need for a just transition.

Furthermore, there is a need for public engagement and education on the benefits and challenges of decarbonization. Canadians must understand how changes in energy policy will affect their daily lives, from electricity prices to job opportunities. Fostering a sense of community involvement can help build support for renewable energy initiatives and ensure that diverse voices are heard in the planning process.

Policy Recommendations

For Canada to successfully decarbonize its electricity grid, and building on recent electricity progress across provinces nationwide, robust and forward-thinking policies must be implemented. This includes investment in research and development to advance renewable technologies and improve energy storage solutions. Additionally, policies should encourage public-private partnerships to share the financial burden of infrastructure investments.

Governments at all levels should also promote energy efficiency measures to reduce overall demand, making the transition more manageable. Incentives for consumers to adopt renewable energy solutions, such as solar panels, can further accelerate the shift towards a decarbonized grid.

Decarbonizing Canada's electricity grid presents a complex yet necessary challenge. While there are economic, reliability, and social considerations to navigate, the potential benefits of a cleaner, more sustainable energy future are substantial. By implementing thoughtful policies and fostering community engagement, Canada can lead the way in creating an electricity grid that not only meets the needs of its citizens but also contributes to global efforts in combating climate change.

Russia-Ukraine Energy Ceasefire explores halting strikes on power plants, safeguarding energy infrastructure and grids, easing humanitarian crises, stabilizing European markets, and advancing diplomatic talks on security, resilience, and critical infrastructure protection.

Key Points

A proposed pact to halt strikes on power plants, protect energy infrastructure, and stabilize grids and security.

✅ Shields power plants and grid infrastructure from attacks

✅ Eases humanitarian strain and improves winter resilience

✅ Supports European energy security and market stability

In a significant diplomatic development amid ongoing conflict, Russia and Ukraine are reportedly exploring the possibility of reaching an agreement to halt attacks on each other’s power plants. This potential cessation of hostilities could have far-reaching implications for the energy security and stability of both nations, as well as for the broader European energy landscape.

The Context of Energy Warfare

The conflict between Russia and Ukraine has escalated into what many analysts term "energy warfare," where both sides have targeted each other’s energy infrastructure. Such actions not only aim to undermine the adversary’s military capabilities but also have profound effects on civilian populations, leading to widespread power outages and humanitarian crises. Energy infrastructure has become a focal point in the conflict, with power plants and grids frequently damaged or destroyed.

The ongoing hostilities have raised concerns about energy security in Europe, with some warning of an energy nightmare if disruptions escalate, especially as many countries in the region rely on energy supplies from Russia. The attacks on power facilities exacerbate vulnerabilities in the energy supply chain, prompting calls for a ceasefire that encompasses energy infrastructure.

The Humanitarian Implications

The humanitarian impact of the conflict has been staggering, with millions of civilians affected by power outages, heating shortages, and disrupted access to essential services. The winter months, in particular, pose a grave challenge, as Ukraine prepares for winter amid ongoing energy constraints for vulnerable populations. A potential agreement to cease attacks on power plants could provide much-needed relief and stability for civilians caught in the crossfire.

International organizations, including the United Nations and various humanitarian NGOs, have been vocal in urging both parties to prioritize civilian safety and to protect critical infrastructure. Any agreement reached could facilitate aid efforts and enhance the overall humanitarian situation in affected areas.

Diplomatic Efforts and Negotiations

Reports indicate that diplomatic channels are being utilized to explore this potential agreement. While the specifics of the negotiations remain unclear, the idea of protecting energy infrastructure has been gaining traction among international diplomats. Key players, including European nations and the United States, with debates over U.S. energy security shaping positions, may play a pivotal role in mediating discussions.

Negotiating a ceasefire concerning energy infrastructure could serve as a preliminary step toward broader peace talks. By demonstrating goodwill through a tangible agreement, both parties might foster an environment conducive to further negotiations on other contentious issues in the conflict.

The Broader European Energy Landscape

The ramifications of an agreement between Russia and Ukraine extend beyond their borders. The stability of energy supplies in Europe is inextricably linked to the dynamics of the conflict, and the posture of certain EU states, such as Hungary's energy alliance with Russia, also shapes outcomes across the region. Many European nations have been grappling with rising energy prices and supply uncertainties, particularly in light of reduced gas supplies from Russia.

A halt to attacks on power plants could alleviate some of the strain on energy markets, which have experienced price hikes and instability in recent months, helping to stabilize prices and improve energy security for neighboring countries. Furthermore, it could pave the way for increased cooperation on energy issues, such as joint projects for renewable energy development or grid interconnections.

Future Considerations

While the prospect of an agreement is encouraging, skepticism remains about the willingness of both parties to adhere to such terms. The historical context of mistrust and previous violations of ceasefires, as both sides have accused each other of violations in recent months, raises questions about the durability of any potential pact. Continued dialogue and monitoring by international entities will be essential to ensure compliance and to build confidence between the parties.

Moreover, as discussions progress, it will be crucial to consider the long-term implications for energy policy in both Russia and Ukraine. The conflict has already prompted Ukraine to seek alternative energy sources and reduce its dependence on Russian gas, turning to electricity imports to keep the lights on, while Russia is exploring new markets for its energy exports.

The potential agreement between Russia and Ukraine to stop targeting each other’s power plants represents a glimmer of hope in a protracted conflict characterized by violence and humanitarian suffering. As both nations explore this diplomatic avenue, the implications for energy security, civilian safety, and the broader European energy landscape could be profound. Continued international support and monitoring will be vital to ensure that any agreement reached translates into real-world benefits for affected populations and contributes to a more stable energy future for the region.

FPL Hurricane Surcharge explained: restoration costs, Florida PSC review, rate impacts, grid resilience, and transparency after Hurricanes Debby and Helene as FPL funds infrastructure hardening and rapid storm recovery across Florida.

Key Points

A fee by Florida Power & Light to recoup hurricane restoration costs, under Florida PSC review for consumer fairness.

✅ Funds Debby and Helene restoration, materials, and crews

✅ Reviewed by Florida PSC for consumer protection and fairness

✅ Raises questions on grid resilience, transparency, and renewables

In the aftermath of recent hurricanes, Florida Power & Light (FPL) is under scrutiny as it implements a rate surcharge, alongside proposed rate hikes that span multiple years, to help cover the costs of restoration and recovery efforts. The surcharges, attributed to Hurricanes Debby and Helene, have stirred significant debate among consumers and state regulators, highlighting the ongoing challenges of hurricane preparedness and response in the Sunshine State.

Hurricanes are a regular threat in Florida, and FPL, as the state's largest utility provider, plays a critical role in restoring power and services after such events. However, the financial implications of these natural disasters often leave residents questioning the fairness and necessity of additional charges on their monthly bills. The newly proposed surcharge, which is expected to affect millions of customers, has ignited discussions about the adequacy of the company’s infrastructure investments and its responsibility in disaster recovery.

FPL’s decision to implement a surcharge comes as the company faces rising operational costs due to extensive damage caused by the hurricanes. Restoration efforts are not only labor-intensive but also require significant investment in materials and equipment to restore power swiftly and efficiently. With the added pressures of increased demand for electricity during peak hurricane seasons, utilities like FPL must navigate complex financial landscapes, similar to Snohomish PUD's weather-related rate hikes seen in other regions, while ensuring reliable service.

Consumer advocacy groups have raised concerns over the timing and justification for the surcharge. Many argue that frequent rate increases following natural disasters can strain already financially burdened households, echoing pandemic-related shutoff concerns raised during COVID that heightened energy insecurity. Florida residents are already facing inflationary pressures and rising living costs, making additional surcharges particularly difficult for many to absorb. Critics assert that utility companies should prioritize transparency and accountability, especially when it comes to costs incurred during emergencies.

The Florida Public Service Commission (PSC), which regulates utility rates and services, even as California regulators face calls for action amid soaring bills elsewhere, is tasked with reviewing the surcharge proposal. The commission’s role is crucial in determining whether the surcharge is justified and in line with the interests of consumers. As part of this process, stakeholders—including FPL, consumer advocacy groups, and the general public—will have the opportunity to voice their opinions and concerns. This input is essential in ensuring that the commission makes an informed decision that balances the utility’s financial needs with consumer protection.

In recent years, FPL has invested heavily in strengthening its infrastructure to better withstand hurricane impacts. These investments include hardening power lines, enhancing grid resilience, and implementing advanced technologies for quicker recovery, with public outage prevention tips also promoted to enhance preparedness. However, as storms become increasingly severe due to climate change, the question arises: are these measures sufficient? Critics argue that more proactive measures are needed to mitigate the impacts of future storms and reduce the reliance on post-disaster rate increases.

Additionally, the conversation around climate resilience is becoming increasingly prominent in discussions about energy policy in Florida. As extreme weather events grow more common, utilities are under pressure to innovate and adapt their systems. Some experts suggest that FPL and other utilities should explore alternative strategies, such as investing in decentralized energy resources like solar and battery storage, even as Florida declined federal solar incentives that could accelerate adoption, which could provide more reliable service during outages and reduce the overall strain on the grid.

The issue of rate surcharges also highlights a broader conversation about the energy landscape in Florida. With a growing emphasis on renewable energy and sustainability, consumers are becoming more aware of the environmental impacts of their energy choices, and some recall a one-time Gulf Power bill decrease as an example of short-term relief. This shift in consumer awareness may push utilities like FPL to reevaluate their business models and explore more sustainable practices that align with the public’s evolving expectations.

As FPL navigates the complexities of hurricane recovery and financial sustainability, the impending surcharge serves as a reminder of the ongoing challenges faced by utility providers in a climate-volatile world. While the need for recovery funding is undeniable, the manner in which it is implemented and communicated will be crucial in maintaining public trust and ensuring fair treatment of consumers. As discussions unfold in the coming weeks, all eyes will be on the PSC’s decision and FPL’s approach to balancing recovery efforts with consumer affordability.

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.
