REV Campus Challenge Receives $2 MILLION in Funding

Sault Ste. Marie Smart Grid Investment upgrades PUC Distribution infrastructure with federal funding, clean energy tech, outage reduction, customer insights, and reliability gains, creating 140 jobs and attracting industry to a resilient, efficient grid.

Key Points

A federally funded PUC Distribution project to modernize the citywide grid, cut outages, boost efficiency, and create jobs.

✅ $11.8M federal funding to PUC Distribution

✅ Citywide smart grid cuts outages and energy loss

✅ 140 jobs; attracts clean tech and industry

PUC Distribution Inc. in Sault Ste. Marie is receiving $11.8 million from the federal government to invest in infrastructure, as utilities nationwide have faced pandemic-related losses that underscore the need for resilient systems.

The MP for the riding, Terry Sheehan, made the announcement on Monday.

The money will go to the utility's smart grid project, where technologies like a centralized SCADA system can enhance situational awareness and control.

"This smart grid project offers a glimpse into our clean energy future and represents a new wave of economic activity for the region," Sheehan said.

"Along with job creation, new industries will be attracted to a modern grid, supported by stable electricity pricing that helps competitiveness, all while helping the environment."

His office says the investment will allow the utility to reduce outages, provide more information to customers to help make smarter electricity use choices, aligned with Ontario's energy-efficiency programs that encourage conservation, and offer more services.

"This is an innovative project that makes Sault Ste. Marie a leader," mayor Christian Provenzano said.

"We will be the first city in our country to implement a community-wide smart grid. Once it is complete, the smart grid will make our energy infrastructure more reliable, reduce energy loss and lead to a more innovative economy for our community."

The project will also create 140 new jobs.

"As a community-focused utility, we are always looking for innovative ways to help our customers save money amid concerns about hydro disconnections during winter, and reduce their carbon footprint," Rob Brewster, president and CEO of PUC Distribution said.

"The investment the government has made in our community will not only help modernize our city's electrical distribution system [as] once the project is complete, Sault Ste. Marie will have access to an electricity grid that can handle the growing demands of a city in the 21st century."

Noncarbon Electricity Investment Strategy helps utilities hedge policy uncertainty, carbon tax risks, and emissions limits by scaling wind, solar, and CCS, avoiding stranded assets while balancing costs, reliability, and climate policy over decades.

Key Points

A strategy for utilities to invest 20-30 percent of capacity in low carbon sources to hedge emissions and carbon risks.

✅ Hedges future carbon tax and emissions limits

✅ Targets 20-30 percent of new generation from clean sources

✅ Reduces stranded asset risk and builds renewables capacity

When utility executives make decisions about building new power plants, a lot rides on their choices. Depending on their size and type, new generating facilities cost hundreds of millions or even billions of dollars. They typically will run for 40 or more years — 10 U.S. presidential terms. Much can change during that time.

Today one of the biggest dilemmas that regulators and electricity industry planners face is predicting how strict future limits on greenhouse gas emissions will be. Future policies will affect the profitability of today’s investments. For example, if the United States adopts a carbon tax 10 years from now, it could make power plants that burn fossil fuels less profitable, or even insolvent.

These investment choices also affect consumers. In South Carolina, utilities were allowed to charge their customers higher rates to cover construction costs for two new nuclear reactors, which have now been abandoned because of construction delays and weak electricity demand. Looking forward, if utilities are reliant on coal plants instead of solar and wind, it will be much harder and more expensive for them to meet future emissions targets, even as New Zealand's electrification push accelerates abroad. They will pass the costs of complying with these targets on to customers in the form of higher electricity prices.

With so much uncertainty about future policy, how much should we be investing in noncarbon electricity generation in the next decade? In a recent study, we proposed optimal near-term electricity investment strategies to hedge against risks and manage inherent uncertainties about the future.

We found that for a broad range of assumptions, 20 to 30 percent of new generation in the coming decade should be from noncarbon sources such as wind and solar energy across markets. For most U.S. electricity providers, this strategy would mean increasing their investments in noncarbon power sources, regardless of the current administration’s position on climate change.

Many noncarbon electricity sources — including wind, solar, nuclear power and coal or natural gas with carbon capture and storage — are more expensive than conventional coal and natural gas plants. Even wind power, which is often mentioned as competitive, is actually more costly when accounting for costs such as backup generation and energy storage to ensure that power is available when wind output is low.

Over the past decade, federal tax incentives and state policies designed to promote clean electricity sources spurred many utilities to invest in noncarbon sources. Now the Trump administration is shifting federal policy back toward promoting fossil fuels. But it can still make economic sense for power companies to invest in more expensive noncarbon technologies if we consider the potential impact of future policies.

How much should companies invest to hedge against the possibility of future greenhouse gas limits? On one hand, if they invest too much in noncarbon generation and the federal government adopts only weak climate policies throughout the investment period, utilities will overspend on expensive energy sources.

On the other hand, if they invest too little in noncarbon generation and future administrations adopt stringent emissions targets, utilities will have to replace high-carbon energy sources with cleaner substitutes, which could be extremely costly.

Economic modeling with uncertainty

We conducted a quantitative analysis to determine how to balance these two concerns and find an optimal investment strategy given uncertainty about future emissions limits. This is a core choice that power companies have to make when they decide what kinds of plants to build.

First we developed a computational model that represents the sectors of the U.S. economy, including electric power. Then we embedded it within a computer program that evaluates decisions in the electric power sector under policy uncertainty.

The model explores different electric power investment decisions under a wide range of future emissions limits with different probabilities of being implemented. For each decision/policy combination, it computes and compares economy-wide costs over two investment periods extending from 2015 to 2030.

We looked at costs across the economy because emissions policies impose costs on consumers and producers as well as power companies. For example, they may lead to higher electricity, fuel or product prices. By seeking to minimize economy-wide costs, our model identifies the investment decision that produces the greatest overall benefits to society.

More investments in clean generation make economic sense

We found that for a broad range of assumptions, the optimal investment strategy for the coming decade is for 20 to 30 percent of new generation to be from noncarbon sources. Our model identified this as the best level because it best positions the United States to meet a wide range of possible future policies at a low cost to the economy.

From 2005-2015, we calculated that about 19 percent of the new generation that came online was from noncarbon sources. Our findings indicate that power companies should put a larger share of their money into noncarbon investments in the coming decade.

While increasing noncarbon investments from a 19 percent share to a 20 to 30 percent share of new generation may seem like a modest change, it actually requires a considerable increase in noncarbon investment dollars. This is especially true since power companies will need to replace dozens of aging coal-fired power plants that are expected to be retired.

In general, society will bear greater costs if power companies underinvest in noncarbon technologies than if they overinvest. If utilities build too much noncarbon generation but end up not needing it to meet emissions limits, they can and will still use it fully. Sunshine and wind are free, so generators can produce electricity from these sources with low operating costs.

In contrast, if the United States adopts strict emissions limits within a decade or two, they could prevent carbon-intensive generation built today from being used. Those plants would become “stranded assets” — investments that are obsolete far earlier than expected, and are a drain on the economy.

Investing early in noncarbon technologies has another benefit: It helps develop the capacity and infrastructure needed to quickly expand noncarbon generation. This would allow energy companies to comply with future emissions policies at lower costs.

Seeing beyond one president

The Trump administration is working to roll back Obama-era climate policies such as the Clean Power Plan, and to implement policies that favor fossil generation. But these initiatives should alter the optimal strategy that we have proposed for power companies only if corporate leaders expect Trump’s policies to persist over the 40 years or more that these new generating plants can be expected to run.

Energy executives would need to be extremely confident that, despite investor pressure from shareholders, the United States will adopt only weak climate policies, or none at all, into future decades in order to see cutting investments in noncarbon generation as an optimal near-term strategy. Instead, they may well expect that the United States will eventually rejoin worldwide efforts to slow the pace of climate change and adopt strict emissions limits.

In that case, they should allocate their investments so that at least 20 to 30 percent of new generation over the next decade comes from noncarbon sources. Sustaining and increasing noncarbon investments in the coming decade is not just good for the environment — it’s also a smart business strategy that is good for the economy.

Smart solar inverters anchor DER communications and control, meeting IEEE 1547 and California Rule 21 for volt/VAR, reactive power, and ride-through, expanding hosting capacity and enabling grid services via secure real-time telemetry and commands.

Key Points

Smart solar inverters use IEEE 1547, volt/VAR and reactive power to stabilize circuits and integrate DER safely.

✅ Meet IEEE 1547, Rule 21 ride-through and volt/VAR functions

✅ Support reactive power to manage voltage and hosting capacity

✅ Enable utility communications, telemetry, and grid services

Advanced solar inverters could be one of the biggest distributed energy resource communications and control points out there someday. With California now requiring at least early-stage “smart” capabilities from all new solar projects — and a standards road map for next-stage efforts like real-time communications and active controls — this future now has a template.

There are still a lot of unanswered questions about how smart inverters will be used.

That was the consensus at Intersolar this week, where experts discussed the latest developments on the U.S. smart solar inverter front. After years of pilot projects, multi-stakeholder technical working groups, and slow and steady standards development, solar smart inverters are finally starting to hit the market en masse — even if it’s not yet clear just what will be done with them once they’re installed.

“From the technical perspective, the standards are firm,” Roger Salas, distribution engineering manager for Southern California Edison, said. In September of last year, his utility started requiring that all new solar installations come with “Phase 1" advanced inverter functionality, as defined under the state’s Rule 21.

Later this month, it’s going to start requiring “reactive power priority” for these inverters, and in February 2019, it’s going to start requiring that inverters support the communications capabilities described in “Phase 2,” as well as some more advanced “Phase 3” capabilities.

Increasing hosting capacity: A win-win for solar and utilities

Each of these phases aligns with a different value proposition for smart inverters. The first phase is largely preventative, aimed at solving the kinds of problems that have forced costly upgrades to how inverters operate in solar-heavy Germany and Hawaii.

The key standard in question in the U.S. is IEEE 1547, which sets the rules for what grid-connected DERs must do to stay safe, such as trip offline when the grid goes down, or avoid overloading local transformers or circuits.

The old version of the standard, however, had a lot of restrictive rules on tripping off during relatively common voltage excursions, which could cause real problems on circuits with a lot of solar dropping off all at once.

Phase 1 implementation of IEEE 1547 is all about removing these barriers, Salas said. “They need to be stable, they need to be connected, they need to be able to support the grid.”

This should increase hosting capacity on circuits that would have otherwise been constrained by these unwelcome behaviors, he said.

Reactive power: Where utility and solar imperatives collide

The old versions of IEEE 1547 also didn’t provide rules for how inverters could use one of their more flexible capabilities: the ability to inject or absorb reactive power to mitigate voltage fluctuations, including those that may be caused by the PV itself. The new version opens up this capability, which could allow for an active application of reactive power to further increase hosting capacity, as well as solve other grid edge challenges for utilities.

But where utilities see opportunity, the solar industry sees a threat. Every unit of reactive power comes at the cost of a reduction in the real power output of solar inverters — and almost every solar installation out there is paid based on the real power it produces.

“If you’re tasked to do things that rob your energy sales, that will reduce compensation,” noted Ric O'Connell, executive director of the Oakland, Calif.-based GridLab. “And a lot of systems have third-party owners — the Sunruns, the Teslas — with growing Powerwall fleets — that have contracts, performance guarantees, and they want to get those financed. It’s harder to do that if there’s uncertainty in the future with curtailment."

“That’s the bottleneck right now,” said Daniel Munoz-Alvarez, a GTM Research grid edge analyst. “As we develop markets on the retail end for ...volt/VAR control to be compensated on the grid edge and that is compensated back to the customer, then the customer will be more willing to allow the utility to control their smart inverters or to allow some automation.”

But first, he said, “We need some agreed-upon functions.”

The future: Communications, controls and DER integration

The next stage of smart inverter functionality is establishing communications with the utility. After that, utilities will be able use them to monitor key DER data, or issue disconnect and reconnect commands in emergencies, as well as actively orchestrate other utility devices and systems through emerging virtual power plant strategies across their service areas.

This last area is where Salas sees the greatest opportunity to putting mass-market smart solar inverters to use. “If you want to maximize the DERs and what they can do, the need information from the grid. And DERs provide operational and capability information to the utility.”

Inverter makers have already been forced by California to enable the latest IEEE 1547 capabilities into their existing controls systems — but they are clearly embracing the role that their devices can play on the grid as well. Microinverter maker Enphase leveraged its work in Hawaii into a grid services business, seeking to provide data to utilities where they already had a significant number of installations. While Enphase has since scaled back dramatically, its main rival SolarEdge has taken up the same challenge, launching its own grid services arm earlier this summer.

Inverters have been technically capable of doing most of these things for a long time. But utilities and regulators have been waiting for the completion of IEEE 1547 to move forward decisively. Patrick Dalton, senior engineer for Xcel Energy, said his company’s utilities in Colorado and Minnesota are still several years away from mandating advanced inverter capabilities and are waiting for California’s energy transition example in order to choose a path forward.

In the meantime, it’s possible that Xcel's front-of-meter volt/VAR optimization investments in Colorado, including grid edge devices from startup Varentec, could solve many of the issues that have been addressed by smart inverter efforts in Hawaii and California, he noted.

The broader landscape for rolling out smart inverters for solar installations hasn’t changed much, with Hawaii and California still out ahead of the pack, while territories such as Puerto Rico microgrid rules evolve to support resilience. Arizona is the next most important state, with a high penetration of distributed solar, a contentious policy climate surrounding its proper treatment in future years, and a big smart inverter pilot from utility Arizona Public Service to inform stakeholders.

All told, eight separate smart inverter pilots are underway across eight states at present, according to GTM Research: Pacific Gas & Electric and San Diego Gas & Electric in California; APS and Salt River Project in Arizona; Hawaiian Electric in Hawaii; Duke Energy in North Carolina; Con Edison in New York; and a three-state pilot funded by the Department of Energy’s SunShot program and led by the Electric Power Research Institute.

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

Key Points

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

✅ Lowers wholesale costs via wider dispatch and resource sharing

✅ Improves reliability with regional balancing and reserves

✅ Preserves state policy authority under FERC oversight

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

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

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

Elements of the report

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

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

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

Call to action

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

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

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

US Electricity Demand Stagnation reflects decoupling from GDP as TVA's IRP revises outlook, with energy efficiency, distributed generation, renewables, and cheap natural gas undercutting coal, reshaping utility business models and accelerating grid modernization.

Key Points

US electricity demand stagnation is flat load growth driven by efficiency, DG, and decoupling from GDP.

✅ Flat sales pressure IOU profits and legacy baseload investments.

✅ Efficiency and rooftop solar reduce load growth and capacity needs.

✅ Utilities must pivot to services, DER orchestration, and grid software.

The US electricity sector is in a period of unprecedented change and turmoil, with emerging utility trends reshaping strategies across the industry today. Renewable energy prices are falling like crazy. Natural gas production continues its extraordinary surge. Coal, the golden child of the current administration, is headed down the tubes.

In all that bedlam, it’s easy to lose sight of an equally important (if less sexy) trend: Demand for electricity is stagnant.

Thanks to a combination of greater energy efficiency, outsourcing of heavy industry, and customers generating their own power on site, demand for utility power has been flat for 10 years, with COVID-19 electricity demand underscoring recent variability and long-run stagnation, and most forecasts expect it to stay that way. The die was cast around 1998, when GDP growth and electricity demand growth became “decoupled”:

This historic shift has wreaked havoc in the utility industry in ways large and small, visible and obscure. Some of that havoc is high-profile and headline-making, as in the recent requests from utilities (and attempts by the Trump administration) to bail out large coal and nuclear plants amid coal and nuclear industry disruptions affecting power markets and reliability.

Some of it, however, is unfolding in more obscure quarters. A great example recently popped up in Tennessee, where one utility is finding its 20-year forecasts rendered archaic almost as soon as they are released.

Falling demand has TVA moving up its planning process

Every five years, the Tennessee Valley Authority (TVA) — the federally owned regional planning agency that, among other things, supplies electricity to Tennessee and parts of surrounding states — develops an Integrated Resource Plan (IRP) meant to assess what it requires to meet customer needs for the next 20 years.

The last IRP, completed in 2015, anticipated that there would be no need for major new investment in baseload (coal, nuclear, and hydro) power plants; it foresaw that energy efficiency and distributed (customer-owned) energy generation would hold down demand.

Even so, TVA underestimated. Just three years later, the Times Free Press reports, “TVA now expects to sell 13 percent less power in 2027 than it did two decades earlier — the first sustained reversal in the growth of electricity usage in the 85-year history of TVA.”

TVA will sell less electricity in 10 years than it did 10 years ago. That is bonkers.

This startling shift in prospects has prompted the company to accelerate its schedule. It will now develop its next IRP a year early, in 2019.

Think for a moment about why a big utility like TVA (serving 9 million customers in seven states, with more than $11 billion in revenue) sets out to plan 20 years ahead. It is investing in extremely large and capital-intensive infrastructure like power plants and transmission lines, which cost billions of dollars and last for decades. These are not decisions to make lightly; the utility wants to be sure that they will still be needed, and will still pay off, for many years to come.

Now think for a moment about what it means for the electricity sector to be changing so fast that TVA’s projections are out of date three years after its last IRP, so much so that it needs to plunge back into the multimillion-dollar, year-long process of developing a new plan.

TVA wanted a plan for 20 years; the plan lasted three.

The utility business model is headed for a reckoning

TVA, as a government-owned, fully regulated utility, has only the goals of “low cost, informed risk, environmental responsibility, reliability, diversity of power and flexibility to meet changing market conditions,” as its planning manager told the Times Free Press. (Yes, that’s already a lot of goals!)

But investor-owned utilities (IOUs), which administer electricity for well over half of Americans, face another imperative: to make money for investors. They can’t make money selling electricity; monopoly regulations forbid it, raising questions about utility revenue models as marginal energy costs fall. Instead, they make money by earning a rate of return on investments in electrical power plants and infrastructure.

The problem is, with demand stagnant, there’s not much need for new hardware. And a drop in investment means a drop in profit. Unable to continue the steady growth that their investors have always counted on, IOUs are treading water, watching as revenues dry up

Utilities have been frantically adjusting to this new normal. The generation utilities that sell into wholesale electricity markets (also under pressure from falling power prices; thanks to natural gas and renewables, wholesale power prices are down 70 percent from 2007) have reacted by cutting costs and merging. The regulated utilities that administer local distribution grids have responded by increasing investments in those grids, including efforts to improve electricity reliability and resilience at lower cost.

But these are temporary, limited responses, not enough to stay in business in the face of long-term decline in demand. Ultimately, deeper reforms will be necessary.

As I have explained at length, the US utility sector was built around the presumption of perpetual growth. Utilities were envisioned as entities that would build the electricity infrastructure to safely and affordably meet ever-rising demand, which was seen as a fixed, external factor, outside utility control.

But demand is no longer rising. What the US needs now are utilities that can manage and accelerate that decline in demand, increasing efficiency as they shift to cleaner generation. The new electricity paradigm is to match flexible, diverse, low-carbon supply with (increasingly controllable) demand, through sophisticated real-time sensing and software.

That’s simply a different model than current utilities are designed for. To adapt, the utility business model must change. Utilities need newly defined responsibilities and new ways to make money, through services rather than new hardware. That kind of reform will require regulators, politicians, and risky experiments. Very few states — New York, California, Massachusetts, a few others — have consciously set off down that path.

Flat or declining demand is going to force the issue

Even if natural gas and renewables weren’t roiling the sector, the end of demand growth would eventually force utility reform.

To be clear: For both economic and environmental reasons, it is good that US power demand has decoupled from GDP growth. As long as we’re getting the energy services we need, we want overall demand to decline. It saves money, reduces pollution, and avoids the need for expensive infrastructure.

But the way we’ve set up utilities, they must fight that trend. Every time they are forced to invest in energy efficiency or make some allowance for distributed generation (and they must always be forced), demand for their product declines, and with it their justification to make new investments.

Only when the utility model fundamentally changes — when utilities begin to see themselves primarily as architects and managers of high-efficiency, low-emissions, multidirectional electricity systems rather than just investors in infrastructure growth — can utilities turn in earnest to the kind planning they need to be doing.

In a climate-aligned world, utilities would view the decoupling of power demand from GDP growth as cause for celebration, a sign of success. They would throw themselves into accelerating the trend.

Instead, utilities find themselves constantly surprised, caught flat-footed again and again by a trend they desperately want to believe is temporary. Unless we can collectively reorient utilities to pursue rather than fear current trends in electricity, they are headed for a grim reckoning.

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.
