It certainly can, according to Ecomagination, a high-profile initiative inside GE to make environmentally conscious products that still result in healthy profits.

To the public, the Ecomagination advertising and marketing campaign seems to have put a different face on GE - a conglomerate that makes everything from lightbulbs to TV shows.

But while GE's happy to tout its green credentials, its vice president of Ecomagination, Lorraine Bolsinger, is wary of "greenwashing."

Putting an eco-friendly spin on products to improve a corporate image without the goods to back it up will ultimately set the company - and its financial goals - back, according to Bolsinger, who says she welcomes feedback from environmental activists.

GE Chief Executive Jeffrey Immelt tapped Bolsinger two years ago to lead GE's efforts to capitalize on global environmental problems, from climate change to fresh-water shortages. That responsibility also includes reducing greenhouse gas emissions at GE, which is a member of the U.S. Climate Action Partnership, a collection of industrial businesses lobbying for climate change regulations.

During a tour of GE's labs recently in Niskayuna, N.Y., Bolsinger spoke to CNET News.com about the birth of the Ecomagination "growth strategy," clean technologies on the drawing board, and the tension of going green in Corporate America.

Question: GE was one of the first U.S.-based companies to make a bet and say there was money to be made in cleaner technologies. What was behind the initial push?

Bolsinger: When you look at our company, it's pretty easy to understand why we would have been in the space so early on. You might say we are really smart, we're really progressive, and I'd like to think that. It's also because of the very nature of things that we make. Everything that we make, just about, uses electricity or produces electricity or some kind of energy, some kind of motive power.

Question: You're big in energy.

Bolsinger: We're big in energy, and we invest in energy, so it sort of touches everything that we do. We looked at some trends. (CEO) Jeff Immelt does something called a growth playbook every year with each of his businesses. Think of it as a strategic plan for the next three to five years and beyond.

What he heard over and over were three themes for businesses. One, we are going to see enormous (gross domestic product) growth around the world. Two, we will see a scarcity of resources - scarcity of water, scarcity of (energy) resources, and higher prices that go along with that. And the security of supply is at best questionable and, of course, we see that. And the third theme is that we're going to be living in a world where regulations are going to become more and more stringent, not just in the United States but around the world.

At some point in time, customers are going to say, "I don't want anything but an environmentally friendly product." It won't be acceptable to have something that is cheap but dirty.

So we are at a point in time when we have a group of (energy) technologies in our portfolio, and we have to respond to this. We can either wait to see what happens, or we can get out in front of it. Obviously, Immelt decided to get out in front of it, and so we launched Ecomagination.

Ecomagination is for us, above everything else, a growth strategy. It is a business strategy based on the idea that by investing in technologies to help customers solve these big megatrends that we're seeing, to help them grow sustainably in this world - where there is more regulation, more scarcity, higher energy costs - that we can grow sustainably as well. So what's good for business is good for the environment, and what's good for the environment can be good for business.

Question: Reducing your company's own greenhouse gas emissions is also part of the initiative. Why is that?

Bolsinger: That's a very important piece of this because you don't have a lot of credibility if you're out there, telling everyone else, "You ought to do it, but it's not for us." Is a very important backbone of what we do.

Question: You said you're set to top the $20 billion mark in Ecomagination revenue. Yet it's not a separate division, and you're such a diversified company. How do you count it? Is a cleaner gas turbine part of Ecomagination?

Bolsinger: Yes. In order for something to be an Ecomagination-certified product, it has to have two characteristics - not one or the other, but both. It has to be significantly and measurably better in operating performance as well as environmental performance.

If we got this great green technology, but it's totally unaffordable, we say no, that's not ready to be an ecoproduct. It has to be better, in terms of operating performance for the customer - to give them some economic return - as well as the environmental piece of it. And we use a third party to help in the certification process.

Question: Why do you work with a third party to certify what you're doing?

Bolsinger: We want our claims to be authentic and certifiable. Otherwise, you're a greenwasher. We like tough standards, and I think that one of the marks of whether a process is good or not is whether everything squeaks through. And frankly, not everything does.

I'm glad that not everything makes it through because I think we have to be stringent about this. I find that the environmental-activist community is very unforgiving - that's probably a good thing. I'm sure you know about all the news reports about greenwashing and nonverifiable claims about (carbon) offsets and carbon neutrality. I think we have to be ever-vigilant to never cross that line because it's a long way back.

Question: So if half of your product portfolio is already greener, will it all be, at some point?

Bolsinger: You know, someday, I think we'll stop counting. Don't ask when that is. Maybe when I leave this job, that'll be the day, but we continue to count because we want to be on the record, we want to make sure that we are making progress.

But I do believe that at some point in time, customers are going to say, "I don't want anything but an environmentally friendly product." It won't be acceptable to have something that is cheap but dirty. Do I think that eventually everything is going to be an ecoproduct? I do, at least from the equipment perspective.

Question: How far off is that day?

Bolsinger: I'd say certainly 10 years from now, probably sooner - probably closer to 5.

Question: We're here at your research labs. How do see technology addressing climate change?

Bolsinger: I'd say that when you look at where the world needs to be - let's say we really have to have 80 percent lower (greenhouse gas) emissions by the middle of the century, right? That's the "walking around" numbers that the scientists say.

Eighty percent is huge. So I say in the next 5 to 10 years, we're going to focus on component efficiencies. Making everything more efficient by an order of magnitude, so you might say the GE (aircraft) engine is 15 percent more efficient--that's a good one. The Evolution locomotive with 40 percent lower nitrogen oxide emissions. More efficient lighting. (The list goes on.)

All those component things are doable. I think that the next generation of technologies - say, in the next 10 to 20 years - will revolve more around systems, looking at bigger broader systems play. Because now you need to get 20, 30, 40 percent improvements. We're going to be looking at total air traffic management. Not just making the engine in the airplane a little more efficient--the whole system has to get more efficient.

And further out, it's really transformational technologies. Truly breakthroughs that we don't have on the radar screen today. Or making those breakthroughs more cost-competitive. The next-generation solar, battery technology, biofuels.

We have to work on those today if you are going to be see them 20 years from now - it takes that long to get the infrastructure in place. We're doing the research today on how to make it cost-competitive, deployable, all those things. We've got to be working on those things today if we expect it to be in any way mainstream by midcentury.

Question: How about the nonenergy parts of GE? What does Ecomagination mean to them?

Bolsinger: We have more folks wanting to create certified products than we could have imagined. It's easy to imagine the technologies that I've already talked about. The energy business already has an enormous (amount of) renewable technologies - everything from biogas turbines to gas turbines to wind and solar, integrated coal gasification. You can understand those.

The surprises for me have been the financial-services business coming to us, creating a green credit card. There's no end to this thing. I didn't think we thought about ecohomes. It just serves as a muse for how our business groups can work together - our water (purification) and energy business, for example.

Question: Has there been any skepticism at all? There are people who don't believe in global warming and climate change. Has that been a barrier at all?

Bolsinger: No, it hasn't. First of all, we took off the table the debate about climate change a long time ago.

There are fewer and fewer people who are skeptics on climate change. People who say, "I don't believe it" or "I don't see it," they kind of are outliers at this point. I think it's much more mainstream. We're past the point of debating the science.

For us, we said we're just going to take reality as it is. So whether you want to debate climate change until the cows come home doesn't matter. The world is moving in that direction. There is scarcity of resources, there is regulation coming, so let's deal with the world we have. We can keep debating. What's the point of that? The world's has moved on, and we need to keep pace with that.

I think the skepticism piece was never a big deal for me because (Ecomagination) was never based on "we're doing this for philanthropy" or "we're doing this to make the world safe." We're glad to be doing that as a result of making money. It's a different lens that informs your decisions about where to spend money and what resources you're going to invest.

Question: Has there been resistance internally? This is a big change. Has it caused conflicts?

Bolsinger: Not conflicts. I know everybody wants to tell that story that everybody was skeptical. I think the biggest concern in the very beginning was that we didn't overstate things. We didn't turn into this big green machine.

We've been around for more than 120 years. We have legacy issues. Of course we do. I think you always have to be very careful that you don't step out and try to be holier than thou. You have to do what you're good at.

So I wouldn't call it skepticism. I would call it healthy concern that we get it right. I have an eco-advisory boardÂ…. We bring in outsiders to tell us how we are doing because I think it's important.

So I wouldn't say skeptics. I'd say there is tension in the businesses - the kind of tension that you want. Tension means that there is movement. If there's no tension, then it's business as usual - you just call it Ecomagination, and you're not doing anything different.

I like the tension. The tension comes when we introduce the GE Money (business) to the energy financial-services (business), and we say, "You ought to buy their offsets." And we get these two businesses to work together.

Does it cause tension? Yeah, but look at the result.

I'd say if the only other place that we have concern - and we always have concern - is whether customers embrace it. We have to be careful that the customers don't feel that we are so far out in front of them that they can't keep up.

With New Distributed Energy Rebate, Illinois Could Challenge New York in Utility Innovation

Illinois NextGrid redefines utility, customer, and provider roles with grid modernization, DER valuation, upfront rebates, net metering reform, and non-wires alternatives, leveraging rooftop solar, batteries, and performance signals to enhance reliability and efficiency.

 

Key Points

Illinois NextGrid is an ICC roadmap to value DER and modernize the grid with rebates and non-wires solutions.

✅ Upfront Value-of-DER rebates reward location, time, and performance.

✅ Locational DER reduce peak demand and defer wires and substations.

✅ Encourages non-wires alternatives and data-driven utility planning.

 

How does the electric utility fit in to a rapidly-evolving energy system? That’s what the Illinois Commerce Commission is trying to determine with its new effort, "NextGrid". Together, we’re rethinking the roles of the utility, the customer, and energy solution providers in a 21st-century digital grid landscape.

In some ways, NextGrid will follow in the footsteps of New York’s innovative Reforming the Energy Vision process, a multi-year effort to re-examine how electric utilities and customers interact. A new approach is essential to accelerating the adoption of clean energy technologies and building a smarter electricity infrastructure in the state.

Like REV, NextGrid is gaining national attention for stakeholder-driven processes to reveal new ways to value distributed energy resources (DER), like rooftop solar and batteries. New York and Illinois’ efforts also seek alternatives, such as virtual power plants, to simply building more and more wires, poles, and power plants to meet the energy needs of tomorrow.

Yet, Illinois is may go a few steps beyond New York, creating a comprehensive framework for utilities to measure how DER are making the grid smarter and more efficient. Here is what we know will happen so far.

On Wednesday, April 5, at the second annual Grid Modernization Forum in Chicago, I’ll be discussing why these provisions could change the future of our energy system, including insights on grid modernization affordability for stakeholders.

 

Value of distributed energy

The Illinois Commerce Commission’s NextGrid plans grew out of the recently-passed future energy jobs act, a landmark piece of climate and energy policy that was widely heralded as a bipartisan oddity in the age of Trump. The Future Energy Jobs Act will provide significant new investments in renewables and energy efficiency over the next 13 years, redefine the role and value of rooftop solar and batteries on the grid, and lead to significant greenhouse gas emission reductions.

NextGrid will likely start laying the groundwork for valuing distributed energy resources (DER) as envisioned by the Future Energy Jobs Act, which introduces the concept of a new rebate. Illinois currently has a net metering policy, which lets people with solar panels sell their unused solar energy back to the grid to offset their electric bill. Yet the net metering policy had an arbitrary “cap,” or a certain level after which homes and businesses adding solar panels would no longer be able to benefit from net metering.

Although Illinois is still a few years away from meeting that previous “cap,” when it does hit that level, the new policy will ensure additional DER will still be rewarded. Under the new plan, the Value-of-DER rebate will replace net metering on the distribution portion of a customer’s bill (the charge for delivering electricity from the local substation to your house) with an upfront payment, which credits the customer for the value their solar provides to the local grid over the system’s life. Net metering for the energy supply portion of the bill would remain – i.e. homes and businesses would still be able to offset a significant portion of their electric bills by selling excess energy.

What is unique about Illinois’ approach is that the rebate is an upfront payment, rather than on ongoing tariff or reduced net metering compensation, for example. By allowing customers to get paid for the value solar provides to the system at the time it is installed, in the same way new wires, poles, and transformers would, this upfront payment positions DER investments as equally or more beneficial to customers and the electric grid. This is a huge step not only for regulators, but for utilities as well, as they begin to see distributed energy as an asset to the system.

This is a huge step for utilities, as they begin to see distributed energy as an asset to the system.

The rebate would also factor-in the variables of location, time, and performance of DER in the rebate formula, allowing for a more precise calculation of the value to the grid. Peak electricity demand can stress the local grid, causing wear and tear and failure of the equipment that serve our homes and businesses. Power from DER during peak times and in certain areas can alleviate those stresses, therefore providing a greater value than during times of average demand.

In addition, factoring-in the value of performance will take into account the other functions of distributed energy that help keep the lights on. For example, batteries and advanced inverters can provide support for helping avoid voltage fluctuations that can cause outages and other costs to customers.

US Approves Rule to Boost Renewable Transmission

FERC Transmission Rule accelerates grid modernization and interregional high-voltage lines, enabling renewable energy integration, load balancing, and reliability to advance net-zero goals while strengthening resilience, capacity expansion, and decarbonization across U.S. regional transmission organizations.

 

Key Points

A federal policy mandating interregional grid planning and cost sharing to expand high-voltage lines for renewables.

✅ Expands interregional high-voltage transmission capacity

✅ Improves reliability, resilience, and load balancing

✅ Aligns cost allocation and long-term planning for renewables

 

On May 13th, 2024, the US took a monumental step towards its clean energy goals. The Federal Energy Regulatory Commission (FERC) approved a long-awaited rule designed to significantly expand the transmission of renewable energy across the nation's power grid, a US grid overhaul that many advocates say was overdue. This decision aligns with President Biden's ambitious plan to achieve net-zero carbon emissions by 2050, with renewable energy playing a central role.

The new rule tackles a critical bottleneck hindering the widespread adoption of renewables – transmission infrastructure. Unlike traditional power plants like coal or natural gas that run constantly, solar and wind power generation fluctuates with weather conditions. This variability poses a challenge for the existing grid, which is not designed to efficiently handle large-scale integration of these intermittent sources, helping explain why the grid isn't 100% renewable today.

The FERC rule aims to address this by promoting the construction of new, high-voltage transmission lines, particularly those connecting different regions, where grid limitations in the Pacific Northwest have highlighted the need for better interregional transfers. This improved connectivity would allow for a more strategic distribution of renewable energy. Imagine solar energy harnessed in the sun-drenched Southwest being transmitted eastward to meet peak demand during hot summer days on the Atlantic Coast.

The benefits of this expanded transmission network are multifaceted. First, it unlocks the full potential of renewable resources by allowing for their efficient utilization across the country, a trend consistent with wind and solar surpassing coal in U.S. generation. Abundant wind power in the Midwest could be utilized on the West Coast, while surplus solar energy from the South could supplement demand in the Northeast.

Second, a more robust grid with a higher capacity for renewables reduces reliance on fossil fuel-based power plants and complements other ways to meet decarbonization goals across sectors. This translates to cleaner air and a significant reduction in greenhouse gas emissions, contributing to the fight against climate change.

Third, a modernized grid with improved long-distance transmission bolsters the nation's energy security. Extreme weather events, a growing concern due to climate change, can disrupt energy production in specific regions. This interconnected grid would provide a buffer, ensuring a more reliable and resilient power supply and helping put regions on the road to 100% renewables even during adverse weather conditions.

The FERC's decision is a win for environmental groups and the renewable energy industry. They see it as a critical step towards a cleaner energy future and a significant driver of job creation in the construction and maintenance of new transmission lines. However, concerns have been raised by some stakeholders, particularly investor-owned utilities. They worry about the potential cost burden associated with building these expansive new lines, and recent reports of stalled grid spending underscore those concerns and the need for efficient cost allocation mechanisms. Striking a balance between efficiency, affordability, and environmental responsibility will be crucial for the successful implementation of this policy.

Michigan utilities propose more than $20M in EV charging programs

Michigan EV time-of-use charging helps DTE Energy and Consumers Energy manage off-peak demand, expand smart charger rebates, and build DC fast charging infrastructure, lowering grid costs, emissions, and peak load impacts across Michigan's distribution networks.

 

Key Points

Michigan utility programs using time-based EV rates to shift charging off-peak and ease grid load via charger rebates.

✅ Off-peak rates cut peak load and distribution transformer stress.

✅ Rebates support home smart chargers and DC fast charging sites.

✅ DTE Energy and Consumers Energy invest to expand EV infrastructure.

 

The two largest utilities in the state of Michigan, DTE Energy and Consumers Energy, are looking at time-of-use charging rates in two proposed electric vehicle (EV) charging programs, aligned with broader EV charging infrastructure trends among utilities, worth a combined $20.5 million of investments.

DTE Energy last month proposed a $13 million electric vehicle (EV) charging program, which would include transformer upgrades/additions, service drops, labor and contractor costs, materials, hardware and new meters to provide time-of-use charging rates amid evolving charging control dynamics in the market. The Charging Forward program aims to address customer education and outreach, residential smart charger support and charging infrastructure enablement, DTE told regulators in its 1,100-page filing. The utility requested that rebates provided through the program be deferred as a regulatory asset.

Consumers Energy in 2017 withdrew a proposal to install 800 electric vehicle charging ports in its Michigan service territory after questions were raised over how to pay for the $15 million plan. According to Energy News Network, the utility has filed a modified proposal building on the former plan and conversations over the last year that calls for approximately half of the original investment.

Utilities across the country are viewing new demand from EVs as a potential boon to their systems, a shift accelerated by the Model 3's impact on utility planning, potentially allowing greater utilization and lower costs. But that will require the vehicles to be plugged in when other demand is low, to avoid the need for extensive upgrades and more expensive power purchases. Michigan utilities' proposal focuses on off-peak EV charging, as well as on developing new EV infrastructure.

While adoption has remained relatively low nationally, last year the Edison Electric Institute and the Institute for Electric Innovation forecast 7 million EVs on United States' roads by the end of 2025. But unless those EVs can be coordinated, state power grids could face increased stress, the National Renewable Energy Laboratory has said distribution transformers may need to be replaced more frequently and peak load could push system limits — even with just one or two EVs on a neighborhood circuit. 

In its application, DTE told regulators that electrification of transportation offers a range of benefits including "reduced operating costs for EV drivers and affordability benefits for utility customers."

"Most EV charging takes place overnight at home, effectively utilizing distribution and generation capacity in the system during a low load period," the utility said. "Therefore, increased EV adoption puts downward pressure on rates by spreading fixed costs over a greater volume of electric sales."

DTE added that other benefits include reduced carbon emissions, improved air quality, increased expenditures in local economies and reduced dependency on foreign oil for the public at large.

A previous proposal from Consumers Energy included 60 fast charging DC stations along major highways in the Lower Peninsula and 750 240-volt AC stations in metropolitan areas. Consumers' new plan will offer rebates for charger installation, as U.S. charging networks jostle for position amid federal electrification efforts, including residential and DC fast-charging stations.

US Electricity Prices Rise Most in 41 Years as Inflation Endures

US Electricity Price Surge drives bills as BLS data show 15.8 percent jump; natural gas and coal costs escalate amid energy crisis, NYISO warns of wholesale prices and winter futures near $200 per MWh.

 

Key Points

A sharp rise in power bills driven by higher natural gas and coal costs and tighter wholesale markets.

✅ BLS reports electricity bills up 15.8% year over year

✅ Natural gas bills up 33% as fuel costs soar

✅ NYISO flags winter wholesale prices near $200/MWh

 

Electricity bills for US consumers jumped the most since 1981, gaining 15.8% from the same period a year ago, according to the US Bureau of Labor Statistics, and residential bills rose 5% in 2022 across the U.S.

Natural gas bills, which crept back up last month after dipping in July, surged 33% from the same month last year, labor data released Tuesday showed, as electricity and natural gas pricing dynamics continue to ripple through markets. Broader energy costs slipped for a second consecutive month because of lower gasoline and fuel oil prices. Even with that drop, total energy costs were still about 24% above August 2021 levels.

Electricity costs are relentlessly climbing because prices for the two biggest power-plant fuels -- natural gas and coal -- have surged in the last year as the US economy rebounds from the pandemic and as Russia’s war in Ukraine triggers an energy crisis in Europe, where German electricity prices nearly doubled over a year. Another factor is the hot and humid summer across most of the lower 48 states drove households and businesses to crank up air conditioners. Americans likely used a record amount of power in the third quarter, according to US Energy Information Administration projections, even as U.S. power demand is seen sliding 1% in 2023 on milder weather.

New York’s state grid operator warned of a “sharp rise in wholesale electric costs expected this winter” with spiking global demand for fossil fuels, lagging supply and instability from Russia’s war in Ukraine driving up oil and gas prices, with multiple energy-crisis impacts on U.S. electricity and gas still unfolding, according to a Tuesday report. Geopolitical factors are ultimately reflected in wholesale electricity prices and supply charges to consumer bills, the New York Independent System Operator said, and as utilities direct more spending to delivery rather than production.

Electricity price futures for this winter have increased fourfold from last year, and potential deep-freeze disruptions to the energy sector could add volatility, with prices averaging near $200 a megawatt-hour, the grid operator said. That has been driven by natural gas futures for the upcoming winter, which are more than double current prices to nearly $20 per million British thermal units.

Ontario prepares to extend disconnect moratoriums for residential electricity customers

Ontario Electricity Relief outlines an extended disconnect moratorium, potential time-of-use price changes, and Ontario Energy Board oversight to support residential customers facing COVID-19 hardship and bill payment challenges during the emergency in Ontario.

 

Key Points

Plan to extend disconnect moratorium and weigh time-of-use price relief for residential customers during COVID-19.

✅ Extends winter disconnect ban by 3 months

✅ Considers time-of-use price adjustments

✅ Requires Ontario Energy Board approval

 

The Ontario government is preparing to announce electricity relief for residential electricity users struggling because of the COVID-19 emergency, according to sources.

Sources close to those discussions say a decision has been made to lengthen the existing five-month disconnect moratorium by an additional three months.

Separately, Hydro One's relief fund has offered support to its customers during the pandemic.

News releases about the moratorium extension are currently being drafted and are expected to be released shortly, as the pandemic has reduced electricity usage across Ontario.

Electricity utilities in Ontario are currently prohibited from disconnecting residential customers for non-payment during the winter ban period from November 15 to April 30.

The province is also looking at providing further relief by adjusting time-of-use prices, such as off-peak electricity rates, which are designed to encourage shifting of energy use away from periods of high total consumption to periods of low demand.

For businesses, the province has provided stable electricity pricing to support industrial and commercial operations.

But that would require Ontario Energy Board approval and no decision has been finalized, our sources advise.

Purdue: As Ransomware Attacks Increase, New Algorithm May Help Prevent Power Blackouts

Infrastructure Security Algorithm prioritizes cyber defense for power grids and critical infrastructure, mitigating ransomware, blackout risks, and cascading failures by guiding utilities, regulators, and cyber insurers on optimal security investment allocation.

 

Key Points

An algorithm that optimizes security spending to cut ransomware and blackout risks across critical infrastructure.

✅ Guides utilities on optimal security allocation

✅ Uses incentives to correct human risk biases

✅ Prioritizes assets to prevent cascading outages

 

Millions of people could suddenly lose electricity if a ransomware attack just slightly tweaked energy flow onto the U.S. power grid, as past US utility intrusions have shown.

No single power utility company has enough resources to protect the entire grid, but maybe all 3,000 of the grid's utilities could fill in the most crucial security gaps if there were a map showing where to prioritize their security investments.

Purdue University researchers have developed an algorithm to create that map. Using this tool, regulatory authorities or cyber insurance companies could establish a framework for protecting the U.S. power grid that guides the security investments of power utility companies to parts of the grid at greatest risk of causing a blackout if hacked.

Power grids are a type of critical infrastructure, which is any network - whether physical like water systems or virtual like health care record keeping - considered essential to a country's function and safety. The biggest ransomware attacks in history have happened in the past year, affecting most sectors of critical infrastructure in the U.S. such as grain distribution systems in the food and agriculture sector and the Colonial Pipeline, which carries fuel throughout the East Coast, prompting increased military preparation for grid hacks in the U.S.

With this trend in mind, Purdue researchers evaluated the algorithm in the context of various types of critical infrastructure in addition to the power sector, including electricity-sector IoT devices that interface with grid operations. The goal is that the algorithm would help secure any large and complex infrastructure system against cyberattacks.

"Multiple companies own different parts of infrastructure. When ransomware hits, it affects lots of different pieces of technology owned by different providers, so that's what makes ransomware a problem at the state, national and even global level," said Saurabh Bagchi, a professor in the Elmore Family School of Electrical and Computer Engineering and Center for Education and Research in Information Assurance and Security at Purdue. "When you are investing security money on large-scale infrastructures, bad investment decisions can mean your power grid goes out, or your telecommunications network goes out for a few days."

Protecting infrastructure from hacks by improving security investment decisions

The researchers tested the algorithm in simulations of previously reported hacks to four infrastructure systems: a smart grid, industrial control system, e-commerce platform and web-based telecommunications network. They found that use of this algorithm results in the most optimal allocation of security investments for reducing the impact of a cyberattack.

The team's findings appear in a paper presented at this year's IEEE Symposium on Security and Privacy, the premier conference in the area of computer security. The team comprises Purdue professors Shreyas Sundaram and Timothy Cason and former PhD students Mustafa Abdallah and Daniel Woods.

"No one has an infinite security budget. You must decide how much to invest in each of your assets so that you gain a bump in the security of the overall system," Bagchi said.

The power grid, for example, is so interconnected that the security decisions of one power utility company can greatly impact the operations of other electrical plants. If the computers controlling one area's generators don't have adequate security protection, as seen when Russian hackers accessed control rooms at U.S. utilities, then a hack to those computers would disrupt energy flow to another area's generators, forcing them to shut down.

Since not all of the grid's utilities have the same security budget, it can be hard to ensure that critical points of entry to the grid's controls get the most investment in security protection.

The algorithm that Purdue researchers developed would incentivize each security decision maker to allocate security investments in a way that limits the cumulative damage a ransomware attack could cause. An attack on a single generator, for instance, would have less impact than an attack on the controls for a network of generators, which sophisticated grid-disruption malware can target at scale, rather than for the protection of a single generator.

Building an algorithm that considers the effects of human behavior

Bagchi's research shows how to increase cybersecurity in ways that address the interconnected nature of critical infrastructure but don't require an overhaul of the entire infrastructure system to be implemented.

As director of Purdue's Center for Resilient Infrastructures, Systems, and Processes, Bagchi has worked with the U.S. Department of Defense, Northrop Grumman Corp., Intel Corp., Adobe Inc., Google LLC and IBM Corp. on adopting solutions from his research. Bagchi's work has revealed the advantages of establishing an automatic response to attacks, and analyses like Symantec's Dragonfly report highlight energy-sector risks, leading to key innovations against ransomware threats, such as more effective ways to make decisions about backing up data.

There's a compelling reason why incentivizing good security decisions would work, Bagchi said. He and his team designed the algorithm based on findings from the field of behavioral economics, which studies how people make decisions with money.

"Before our work, not much computer security research had been done on how behaviors and biases affect the best defense mechanisms in a system. That's partly because humans are terrible at evaluating risk and an algorithm doesn't have any human biases," Bagchi said. "But for any system of reasonable complexity, decisions about security investments are almost always made with humans in the loop. For our algorithm, we explicitly consider the fact that different participants in an infrastructure system have different biases."

To develop the algorithm, Bagchi's team started by playing a game. They ran a series of experiments analyzing how groups of students chose to protect fake assets with fake investments. As in past studies in behavioral economics, they found that most study participants guessed poorly which assets were the most valuable and should be protected from security attacks. Most study participants also tended to spread out their investments instead of allocating them to one asset even when they were told which asset is the most vulnerable to an attack.

Using these findings, the researchers designed an algorithm that could work two ways: Either security decision makers pay a tax or fine when they make decisions that are less than optimal for the overall security of the system, or security decision makers receive a payment for investing in the most optimal manner.

"Right now, fines are levied as a reactive measure if there is a security incident. Fines or taxes don't have any relationship to the security investments or data of the different operators in critical infrastructure," Bagchi said.

In the researchers' simulations of real-world infrastructure systems, the algorithm successfully minimized the likelihood of losing assets to an attack that would decrease the overall security of the infrastructure system.

Bagchi's research group is working to make the algorithm more scalable and able to adapt to an attacker who may make multiple attempts to hack into a system. The researchers' work on the algorithm is funded by the National Science Foundation, the Wabash Heartland Innovation Network and the Army Research Lab.

Cybersecurity is an area of focus through Purdue's Next Moves, a set of initiatives that works to address some of the greatest technology challenges facing the U.S. Purdue's cybersecurity experts offer insights and assistance to improve the protection of power plants, electrical grids and other critical infrastructure.
