Time and time again, power outages resulting from over demand and complications brought on by extreme weather events like droughts, coastal flooding, and prolonged heat waves continue to disrupt our daily lives and take an ever-increasing financial toll.<\/p>\n\n\n\n<p>The consequences of our global conventional energy profile are nothing short of cascading. The majority of electricity generation comes from burning fossil fuels\u2014approximately <a href=\"https:\/\/ourworldindata.org\/electricity-mix#:~:text=In%202019%2C%20almost%20two%2Dthirds,been%20pretty%20stagnant%20for%20decades.\">63.3%<\/a> (2019)\u2014but as it is commonly known, this process releases greenhouse gases into the atmosphere. This, in turn, warms the planet, which destabilizes natural climate patterns, thereby increasing the number of extreme weather events and their intensities. And in the event of prolonged heat conditions, the amount of electrical load placed on the grid dramatically increases from people turning on their air conditioning units to stay cool.<\/p>\n\n\n\n<p>This has proven to be highly problematic as the entirety of the electrical system, which includes transportation networks necessary for delivering fuel, power plants that generate electricity, and the transmission and distribution lines that funnel power to homes and businesses, was not designed to withstand many of today\u2019s extreme weather conditions. So, as extreme weather becomes more frequent and severe, the cost to fix grid-related damages soars.<\/p>\n\n\n\n<p>In the United States, for example, total costs of severe weather events shot from <a href=\"https:\/\/www.ucsusa.org\/sites\/default\/files\/2019-10\/Power-Failure-How-Climate-Change-Puts-Our-Electricity-at-Risk-and-What-We-Can-Do.pdf\">$20 billion per year in 1980 to $85 billion in 2010<\/a>. From there, a combined total of 25 similar extreme weather events in 2011 and 2012 resulted in over one thousand&nbsp;fatalities and cost the nation a total of $188 billion due to lost output and wages, spoiled inventory, and restarting industrial operations. The recent and infamous power outage in <a href=\"https:\/\/www.scientificamerican.com\/article\/why-the-deep-freeze-caused-texas-to-lose-power\/\">Texas<\/a> is a perfect example of this.<\/p>\n\n\n\n<p>Israel\u2019s electrical grid system has also experienced similar disasters, particularly in its rainy winter months where <a href=\"https:\/\/www.timesofisrael.com\/stormy-weather-brings-power-outages-road-closures-and-flood-warnings\/\">severe windstorms up to 120 kilometers per hour<\/a> have knocked out power across many of the country\u2019s major cities. As for electricity demand, Israel has also experienced its fair share of problems. Ironically, the continued reliance on fossil fuels for electricity generation contributes to this repeating financial and destructive burden.<\/p>\n\n\n\n<p>\u201cThis is indeed something that we are seeing an increase in. If the power consumption goes up, you need more infrastructure to support it, and it\u2019s not always easy to make those necessary changes,\u201d says Razor Labs Project Manager, Yacov Gorovoy.<\/p>\n\n\n\n<p class=\"has-medium-font-size\"><strong>The Collaboration<\/strong><\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" width=\"1024\" height=\"576\" src=\"https:\/\/www.zavit.org.il\/intl\/wp-content\/uploads\/2021\/05\/Untitled-design-1024x576.jpg\" alt=\"\" class=\"wp-image-4745\" srcset=\"https:\/\/www.zavit.org.il\/intl\/wp-content\/uploads\/2021\/05\/Untitled-design-1024x576.jpg 1024w, https:\/\/www.zavit.org.il\/intl\/wp-content\/uploads\/2021\/05\/Untitled-design-300x169.jpg 300w, https:\/\/www.zavit.org.il\/intl\/wp-content\/uploads\/2021\/05\/Untitled-design-768x432.jpg 768w, https:\/\/www.zavit.org.il\/intl\/wp-content\/uploads\/2021\/05\/Untitled-design-1536x864.jpg 1536w, https:\/\/www.zavit.org.il\/intl\/wp-content\/uploads\/2021\/05\/Untitled-design.jpg 1920w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><figcaption><em><sup>Razor Labs and Exacter received funding from the BIRD Energy program in 2019 to forecast and optimize power outages in the American power grid.<\/sup><\/em><\/figcaption><\/figure>\n\n\n\n<p>In the absence of sufficient, government-backed green policies and energy infrastructure, Israeli A.I. company, <a href=\"https:\/\/www.razor-labs.com\/\">Razor Labs<\/a>, is collaborating with Ohio-based company, <a href=\"https:\/\/www.exacterinc.com\/\">Exacter<\/a> Inc., in the development of a <a href=\"https:\/\/research.aimultiple.com\/predictive-maintenance\/#what-is-predictive-maintenance\">predictive maintenance solution<\/a> for electrical grid networks to prevent critical outages from occurring as frequently\u2014saving billions of dollars annually.<\/p>\n\n\n\n<p>Funding and support from the <a href=\"https:\/\/www.birdf.com\/\">BIRD Foundation<\/a> has enabled the two companies to develop and commercialize mobile sensors that that can identify deteriorated equipment and areas within electrical grids and draw connections to environmental factors that likely caused the problem.<\/p>\n\n\n\n<p>\u201cWe and Exacter didn\u2019t have any previous contact,\u201d says Gorovoy. \u201cThe connection was made through the BIRD foundation as they saw that we have a certain base of knowledge and that Exacter needed additional software and data analytics capabilities, and this created the synergy between us that allows us to conduct this project with our own funds and the funds from the grant.\u201d<\/p>\n\n\n\n<p>From this collaboration, their efforts will effectively streamline the management of electrical grid operations such that every component across miles of the distribution grid can be monitored.

When it comes to maintaining and monitoring powerlines and electrical equipment, a utility company can employ one of two options: it can perform preventative maintenance by sending out personnel to inspect a particular component once every two months, for example, regardless of its condition, or reactive maintenance by responding only when the component breaks and needs to be replaced.<\/p>\n\n\n\n<p>On the one hand preventative maintenance involves less down time but it incurs greater costs. On the other hand, reactive maintenance is cheaper, but it usually involves more down time. But from the collaborative efforts between Exacter Inc. and Razor Labs, there is a third and more preferrable option: predictive maintenance.<\/p>\n\n\n\n<p>\u201cThe idea of predictive maintenance, which is what AI and deep learning networks are very efficient at providing, is that you can identify exactly when the need for maintenance would arise,\u201d says Gorovoy.<\/p>\n\n\n\n<p>\u201cFor example, if you have a power line, you can wait until the data shows signs of deterioration. And then, you can save time and effort by not having a routine inspection once every month or two. Instead, you can employ a data driven inspection where the system can tell you to concentrate your maintenance efforts in a specific place at a specific time.\u201d<\/p>\n\n\n\n<p>With Razor Labs\u2019 resources, this method saves a wealth of time and effort because it informs grid operators exactly where to direct their attention rather than taking the time to inspect the entire powerline for the source of the issue. As a result, it leads to less electrical down time in the event of a malfunction or avoid down time altogether at an optimal financial cost.<\/p>\n\n\n\n<p>\u201cIn terms of preventing power outages, predictive maintenance, at least across the United States for example, is a business valued at billions of dollars. Avoiding the cost of power outages, equipment failures, and the harm it causes businesses and private individuals is something that has tremendous value,\u201d Gorovoy adds.<\/p>\n\n\n\n<p class=\"has-medium-font-size\"><strong>How it All Comes Together<\/strong><\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" width=\"608\" height=\"608\" src=\"https:\/\/www.zavit.org.il\/intl\/wp-content\/uploads\/2021\/05\/Sensor-3-edited.png\" alt=\"\" class=\"wp-image-4761\" srcset=\"https:\/\/www.zavit.org.il\/intl\/wp-content\/uploads\/2021\/05\/Sensor-3-edited.png 608w, https:\/\/www.zavit.org.il\/intl\/wp-content\/uploads\/2021\/05\/Sensor-3-edited-300x300.png 300w, https:\/\/www.zavit.org.il\/intl\/wp-content\/uploads\/2021\/05\/Sensor-3-edited-150x150.png 150w\" sizes=\"(max-width: 608px) 100vw, 608px\" \/><figcaption><em><sup>From this collaboration, their efforts will effectively streamline the management of electrical grid operations such that every component across miles of the distribution grid can be monitored.

The proprietary sensors that Exacter\u2019s developed can detect those RF frequencies,\u201d says Gorovoy.<\/p>\n\n\n\n<p>Gorovoy describes the sensors themselves as relatively medium in size as they are designed to be placed onto Exacter-owned vehicles to detect RF signals as the vehicle moves alongside the grid network. \u201cAfter several passes, the sensors can identify areas with persistent readings, and are able to determine the area exemplifying issues,\u201d he elaborates.<\/p>\n\n\n\n<p>\u201cFor this specific project, Exacter developed a second version of their proprietary sensor that\u2019s capable of being installed on vehicles that they do not control. So instead of using their own vehicles, our joint project has a pilot right now in Akron, Ohio, where the sensors are placed on garbage trucks because they usually have a consistent route, and they provide full coverage within a certain window of time.\u201d<\/p>\n\n\n\n<p>At this point, Exacter personnel can interpret the data and determine the approximate source of the issue stemming from the powerline or associated equipment. But the volume of data is quite large, so to expedite this process, the company needs Razor Labs\u2019 expertise in deep machine learning and neural networks to interpret the data patterns more quickly.<\/p>\n\n\n\n<p>\u201cThis is where we come in,\u201d says Gorovoy. \u201cWithout any manual inputs, the sensor sends over the data through the cloud at the end of every day, and we perform analytics on it to create models that output the exact areas where malfunctions are going to happen and to understand the patterns that lead up to that.\u201d<\/p>\n\n\n\n<p>Even with the transition towards renewably generated electricity and the <a href=\"https:\/\/www.ucsusa.org\/sites\/default\/files\/2019-10\/Power-Failure-How-Climate-Change-Puts-Our-Electricity-at-Risk-and-What-We-Can-Do.pdf\">resiliency improvements it will impart to the current grid infrastructure<\/a>, this predictive maintenance technology will still be highly valuable, according to Gorovoy.&nbsp;<\/p>\n\n\n\n<p>\u201cThe collaborative project we are working on focuses on the power lines themselves and their degradation, so as long as electricity is provided via power lines, the solution would still be useful, regardless of how the electricity is produced.\u201d<\/p>\n\n\n\n<p class=\"has-medium-font-size\"><strong>Is It Coming to Israel?<\/strong><\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" width=\"752\" height=\"429\" src=\"https:\/\/www.zavit.org.il\/intl\/wp-content\/uploads\/2021\/05\/Pilot-Grid.png\" alt=\"\" class=\"wp-image-4780\" srcset=\"https:\/\/www.zavit.org.il\/intl\/wp-content\/uploads\/2021\/05\/Pilot-Grid.png 752w, https:\/\/www.zavit.org.il\/intl\/wp-content\/uploads\/2021\/05\/Pilot-Grid-300x171.png 300w\" sizes=\"(max-width: 752px) 100vw, 752px\" \/><figcaption><em><sup>A map detailing points on the electrical grid from the Ohio-based pilot project.
