Expert Commentary
Fleet electrification provides opportunities to achieve climate goals while delivering social, financial, and environmental benefits to individuals, businesses, and communities, but the road to successful EV implementation is not without obstacles. Your EV fleets need to work — all the time under varying conditions — to ensure optimal uptime while maintaining energy efficiency. Consequently, electric vehicle service equipment (EVSE) can’t just be “tacked onto” your existing operation. Rather than a “new standalone addition,” it requires a thoughtful and forward-looking approach to seamlessly integrate into your overall facility. Ensuring the type of reliable power needed for an electrified fleet is critical. Luckily, there are a number of new and emerging solutions that promise to deliver clean and reliable local power generation. The Challenges The availability and reliability of the power needed to support electrified fleets is a primary roadblock for many commercial fleet operators. It’s important to look at where that power comes from, how much it will cost, and whether it will be available when needed. Projections indicate that the demand for electricity will surge by 50% during the next two decades Today’s energy landscape is complex. Projections indicate that the demand for electricity will surge by 50% during the next two decades, with no signs of slowing down. According to Grid Strategies, the U.S. electric grid is not prepared for this level of significant load growth. The sheer amount of power needed to keep trucks charged and running 24/7 can be substantial. This poses a key risk for reliability in EV infrastructures, particularly in mission-critical situations. In addition, most fleet operators have become accustomed to fairly predictable fuel costs, since many take advantage of long-term supply arrangements. By contrast, electricity grid costs can vary and result in unpredictable spikes. This adds an extra layer of complexity when it comes to the planning and timing of fleet charging. As a result, many fleet charging operations are turning to local power generation. Intelligent Microgrids, the Energy Insurance Microgrids are nothing new, with rural communities relying on them for decades. Increased affordability and shifting regulations are allowing for more of these microgrids to be powered by renewable energy methods. A common misconception is that microgrids can completely off-set power from the grid. In reality, they are designed to provide peak load shaving and system resiliency. Coupled with an EV infrastructure, microgrids can offer more flexible and reliable energy management. When compared to a traditional microgrid for a building system, microgrids for fleet electrification present new challenges. Most notably, microgrids for fleet electrification are not modeled on an existing load, but rather anticipated demand, which can make reliable load-based modeling more difficult. However, an "intelligent" microgrid uses control systems to manage, store, charge, and discharge energy across the system. Strategic energy management The system can buy power from the grid during low-cost periods while storing self-generated solar power These controls monitor supply and demand, track real-time electricity prices, and create efficient charging schedules, considering factors like Time of Use (TOU) and peak day rates. For example, when electric fleets plug in, demand may increase significantly overnight, making strategic energy management crucial. The system can buy power from the grid during low-cost periods while storing self-generated solar power for later use. When prices rise, it discharges stored energy, keeping costs stable. It can also operate independently, ensuring continuous power during outages and disruptions, improving efficiency, cost control, and reliability. Conversely, fleets often permit charging flexibility within defined boundaries, providing a unique dispatchable resource that can be tuned to fit the needs and energy resources of the customer. A New Category of Local Power Generation Linear generator technology is proving to be an innovative solution for EV infrastructures by providing flexible, resilient and cost-effective on-site base load power. Linear generator technology provides fuel-flexibility meaning they can directly run and switch among traditional fuels like natural gas or propane. Or, they can use low and zero-carbon fuels such as RNG, biogas, hydrogen, and ammonia. Its backup capabilities ensure power through hurricanes, sub-zero snowstorms, excessive heat, and other extreme conditions. Based on capex and operating costs, linear generators can provide a competitive levelized cost of ownership compared to grid power or other alternatives in certain regions. Net-zero goals These solutions allow for flexibility and integration of new fuels as they become available The technology can also be quickly deployed at scale, which is ideal for large fleet operators looking to quickly and cost-effectively deploy resilient EV charging infrastructure while reducing emissions and working toward net-zero goals. What’s more, linear generators deliver a more “future-proof” path. While the dominant sources of fuel for local power generation today is well understood, new and exciting fuels are on the horizon. These solutions allow for flexibility and integration of new fuels as they become available. All without having to replace or retrofit existing equipment. Experts Will Power the Future As companies look to integrate EVs into their operations, a well-thought-out plan for infrastructure is essential to ensure safety, reliability, and long-term success. The integration of onsite power systems will play a critical role in optimizing energy use, lowering costs, and maintaining system resilience. The good news is that energy management is becoming more flexible, ensuring that fleet electrification is not only sustainable but also cost-effective. To ensure a seamless transition and maximize the benefits of fleet electrification, many companies will be moving forward by working with experienced consultants and planners to create a future-proof infrastructure that meets both operational and environmental goals.

The promise of electric vehicles is closer to reality than ever before. New plans and investments at the federal level designate billions of dollars to move our country toward clean energy, including $2 million to help auto manufacturers retool facilities to increase EV production. Additionally, the Biden Administration has announced a goal to create 100% carbon-free electricity by 2035 and a net-zero carbon economy by 2050. Domestic EV marketplace The domestic EV marketplace has grown from 16,000 to more than 2 million vehicles in the last decade and is poised to expand at lightning speed over the next ten years. S&P Global mobility has predicted that by 2030, electric vehicles (EVs) will make up 40% of the U.S. market share of new vehicles on the road. This dramatic increase in EVs will require a nationwide network of charging stations to meet the demand from the current 140,000 to over 1.1 million. Charging stations It is a necessity that regulators lay the groundwork now for a reliable and secure charging networkThe expansion of charging stations will undoubtedly give zero-emissions drivers more confidence in their ability to refuel more conveniently. Still, it’s critical that confidence in infrastructure security also be prioritized alongside this growth. If not adequately protected and monitored, charging stations could serve as access points for cybercriminals, potentially leading to personal data leaks, attacks on vehicle systems, and even widespread blackouts. As EVs continue to gain momentum as realistic alternatives to CO-2 emitting vehicles, it is a necessity that developers and regulators lay the groundwork now for a reliable and secure charging network for the long term. EV Charging Infrastructure and the electric grid The nation’s electric grid generates and delivers electricity essential to everyday life. It’s made up of power plants and other sources of generated electricity, complete with transmission and distribution lines and infrastructure that delivers essential power. Grid connection An important aspect to remember about EV charging stations is that they connect to their relative electric grid. Simply put, the infrastructure for charging stations is comprised of devices that wait for another device to connect and communicate. However, it lacks a third-party firewall or other devices that can act as protection. Unfortunately, this results in vulnerability and means new doors for cybercriminals to walk through. Cybersecurity risks If the grid became compromised by a large-scale attack, it could lead to destructive and widespread blackouts Even before EV charging stations are factored in, the electric grid faces substantial cybersecurity risks from criminals, terrorists, hackers, and foreign governments every day. If the grid became compromised by a large-scale attack, it could lead to destructive and widespread blackouts that would undoubtedly affect EV charging stations and other essential institutions such as banks, hospitals, and gas stations. With the expansion of EV charging stations, the risks only grow. Now is the time to address threats and strategize before disaster strikes. Risks of connectivity emerge The world we live in has reached a level of being almost entirely connected at all times – security systems, appliances, health monitors, industrial sensors, and now, our vehicles. While the connectivity of vehicles has been incredibly beneficial to consumers and the automotive industry alike, the growth in the internet of things (IoT) has opened countless doorways for cybersecurity threats. Software flaws One young information technology security specialist reported finding flaws within a third-party software that a handful of leading EV manufacturers use. It gave him access to more than 25 EVs in at least 13 countries. The man, who stumbled on the findings in 2022, said he could remotely control some EV functions, including starting vehicles, unlocking windows and doors, disabling security systems, and turning on stereo systems and flashing headlights. The IT specialist said he could also tell if a person was in the vehicle. In a separate and concerning situation, a single compromised password led to a foreign-fronted cyberattack on a U.S.-based pipeline in 2021. It halted the fuel supply process on the east coast and cost the company $4.4 million in ransom money. Cyberattacks Thousands of charging stations are already in danger of being targeted by cybercriminals The point is that even massive and powerful companies can fall victim to cyberattacks. Even though cybersecurity is a critical issue for EV manufacturers, their systems are still vulnerable to hackers. Thousands of charging stations are already in danger of being targeted by cybercriminals, and as the number of stations grows, so too will the risk. The higher the number of entry points, the more opportunities hackers will see. If they can break into and gain access to even the most sophisticated EVs, it could be catastrophic. Ensuring security and reliability through proactivity Because charging stations are connected to the country’s primary grid, the entire infrastructure must be armed with the most aggressive security measures. The risks associated with modernized electric vehicles are not something that traditional automotive safety regulations and security standards properly cover. The complicated and rapid evolution of EVs is putting them at a heightened threat. When charging stations are connected to the electrical grid, it is imperative to ensure strong cybersecurity measures are in place to remain dependable and effective. Embedding cybersecurity technology We often see outside parties utilized to secure tech because of the frequent lack of necessary cyber protection The best way to ensure the electric grid's safety is to build cybersecurity technology directly into the charging stations. We often see outside parties utilized to secure tech because of the frequent lack of necessary cyber protection. Unfortunately, the promising growth EVs and their charging stations bring to our environment also contributes to technology’s vulnerabilities, which can cause key security measures to be overlooked. There’s no getting around it: EV charging stations are highly vulnerable to hackers. Awareness and solutions As the growth continues, there is an acute need for heightened awareness and solutions for the weaknesses associated with these charging stations. These solutions should consider everything from the charging points and devices to operators of the energy distribution networks and infrastructure providers. We must aim to implement advanced cybersecurity measures that will keep safe drivers and all the data that EVs contain.

Packaging materials help to protect fragile electronics and electrical components from breakage. Small electrical devices and electronics are often packaged in individual plastic coverings within a larger box. Manufacturers use a variety of plastics to produce anti-static bags, pouches, film, and bubble wrap for electronics. single-use plastics Excessive consumption of single-use plastics and other packaging materials is an emerging concern in the electrical market. The use of plastic and non-recyclable materials in equipment packaging is contributing to the electrical market’s environmental footprint. organic packaging More electrical manufacturers need to transition towards a more sustainable future and implement organic packaging. Companies can minimize the negative environmental impact and become more green-friendly. While the industry has previously had a negative environmental impact, many businesses are rectifying these issues. Using less paper, plastic, wood, metal packaging, and other auxiliary materials contributes to the goal of being lightweight, recyclable, and sustainable. polystyrene foam Of the total plastic packaging waste, around 40% is disposed of at sanitary landfills Many electrical components are packaged with plastic shrink films. In addition, polystyrene foam can be used to cushion components, and plastic corner protectors may be used to strengthen boxes. Less than 10% of the plastic waste ever generated has been recycled. Plastics pollute the ocean and do not decompose in landfills. Of the total plastic packaging waste, around 40% is disposed of at sanitary landfills, 14% is collected for recycling, and 14% makes its way to incineration facilities (which cause CO2 emissions). The negative impact of plastic The fact is, most plastics used for packaging are recyclable, although most wind up in landfills due to ineffective or non-existent packaging recovery schemes. In addition, plastics contribute to emissions of greenhouse gas at each stage of their lifecycles. Therefore, plastics, which contribute up to 13% of the total “carbon budget,” will negatively impact efforts to meet the Paris climate agreement. action against single-use plastics There is a shift in focus from consumer education to holding manufacturers responsible for their environmental impact Focusing on consumer behavior has spurred much of the campaign against plastics to date. For example, the federal government has taken steps to phase out single-use plastics in national parks and other public lands. Several states have taken action against single-use plastics. For example, New Jersey no longer allows grocery stores and retailers to distribute plastic bags. The Garden State has also banned polystyrene foam packaging from restaurants and food companies. However, there is also a shift in focus from consumer education to holding manufacturers responsible for their environmental impact. Maine and California are focusing on the issue and may be among the jurisdictions to target manufacturers’ role in single-use plastics. replacement alternatives There are replacement alternatives available, but they tend to add costs for manufacturers. For example, bioplastics are made with biodegradable sources that can break down faster than traditional plastics. However, bioplastics must be properly disposed of through composting to break down. Also, bioplastics are not recyclable and can even contaminate other recyclable materials. Disposal in a landfill, which is common, defeats the purpose of using more expensive materials. environmentally friendly alternatives Some argue that recycled plastic may be the greenest alternative, although it results in recyclables winding up in landfills Instead of polystyrene foam, packaging may consist of corrugated cardboard or plastic alternatives that are allegedly more environmentally friendly. Biodegradable wood or paper are other alternatives. However, disposal in landfills continues to be problematic with decomposition sometimes leading to the production of methane (a greenhouse gas). However, some argue that recycled plastic may be the greenest alternative, although recycling realities instead result in recyclables winding up in landfills, where they do not decompose. EPR schemes An added cost for electrical manufacturers might be a requirement to pay into extended producer responsibility (EPR) schemes. EPR is a strategy to add the estimated environmental costs associated with a product’s entire lifecycle to the cost of the product. In effect, the strategy assigns responsibility for the environmental impact of products to the manufacturer. Legislation Legislation to address packaging EPR has been implemented in Maryland, New York, Washington, and New Jersey (originally introduced in 2022 and still active). In 2016, the Product Stewardship Institute developed a model packaging EPR legislation, then updated it in 2019 with input from the industry and government. Maine and Oregon used the model to enact packaging EPR laws in 2021, Colorado followed suit in 2022 and, that same year, California also enacted legislation that the model informed.
The electrical industry is expected to have a labor shortage of about 60,000 workers by 2026. A labor shortage in the electrical trade is not inevitable, but it is likely to continue if the industry does not take steps to address the issue. Like other skilled trades, the electrical industry is facing challenges that could contribute to a labor shortage, including an aging workforce, a lack of interest among younger generations, and competition from other industries. However, there are strategies the industry can implement to address these challenges and attract a new generation of workers. These strategies include increasing awareness of the benefits and opportunities of skilled trades, investing in training and education programs, improving working conditions and compensation, embracing technology, promoting diversity and inclusivity, and collaborating among industry, education, and government. Improving working conditions Factors in the current labor shortage in the electrical industry include: Aging workforce: Many workers in the electrical industry are nearing retirement age, and there are not enough younger workers to replace them. This has led to a shortage of skilled workers with many years of experience in the industry. Lack of interest in the trades: There has been a decline in the number of young people pursuing careers in the skilled trades, including electrical work. This is due in part to a focus on four-year college degrees as the preferred career path, as well as a lack of awareness of the benefits and opportunities of skilled trades. Competition from other industries: The electrical industry is competing with other industries, such as construction and manufacturing, for skilled workers. Training and education: Training and education are critical for developing the skills and knowledge necessary for electrical work. However, there is a shortage of qualified trainers and educators. Increasing demand: The demand for electrical services is increasing, particularly in areas such as renewable energy and smart grid technology. Attracting and retaining workers To attract and retain workers, the electrical industry must offer competitive wages and benefits One strategy to address the labor shortage is to increase awareness of skilled trades and to promote the benefits of a career in the electrical industry through outreach programs in schools, career fairs, and other events. Providing access to quality training and education programs that develop the skills and knowledge necessary for electrical work is crucial for attracting and retaining workers. This can be done through apprenticeship programs, vocational schools, and community colleges. To attract and retain workers, the electrical industry must offer competitive wages and benefits, as well as a safe and supportive work environment. This includes offering training and development opportunities, flexible schedules, and opportunities for advancement. Inclusive work environment The electrical industry is changing rapidly, and workers must be equipped with the latest technology and tools to stay competitive. Providing workers with training and access to the latest technology can help attract and retain workers. The electrical industry should actively promote diversity and inclusivity to attract a wider pool of workers. This includes efforts to recruit workers from underrepresented groups and create a welcoming and inclusive work environment. The electrical industry is changing rapidly, and workers must be equipped with the latest technology Companies in the electrical industry are addressing the labor shortage problem by investing in workforce development programs and initiatives. For example, Schneider Electric has developed a comprehensive workforce development program called the Schneider Electric Energy and Automation Training (SEAT) program. The SEAT program provides training and certification for employees, customers, and partners in areas such as energy management, automation, and digital transformation.

The program provides on-the-job training and education in areas such as electrical theory, safety, and installation. Collaboration among industry, education, and government is crucial for developing solutions to the labor shortage in the electrical industry. This includes partnerships between industry and education institutions to provide training and education programs, as well as government initiatives to support workforce development in the skilled trades.
As our transition to greener energy grows, so does the demand for copper, the highly conductive material at the heart of electrical applications. Copper is spooled up inside electric engines, concealed inside the walls of buildings, and stretched along city streets to transmit power from one point to another. Copper substitutes As demand for electric devices grows, copper supplies are strained, and prices increase. A substitute for copper with similar conductive properties would be especially useful in our environmentally enlightened future. Other metals, including aluminum, are used to conduct electricity in some applications, but aluminum is only 60% as conductive as copper. Scientists have undertaken the task of increasing the conductivity of aluminum to make it viable as a substitute for copper. It would be a game-changer if they are successful, given that aluminum is 1,000 times more abundant than copper on the earth’s surface. Aluminum is also lighter, cheaper, and easier to mine. Developing ultra-conductive aluminum By altering the structure of the metal and introducing the right additives, conductivity properties can be improved At the Pacific Northwest National Laboratory (PNNL), scientists work to address the pressing challenges we face in the future through chemistry. One of those challenges is to develop an ultra-conductive aluminum alternative to copper. PNNL researchers evaluated the effects of temperature and structural defects on aluminum conductivity, seeking a “recipe” to increase its conductivity. By altering the structure of the metal and introducing the right additives, conductivity properties can be improved. molecular simulation Using molecular simulation, the researchers replicated what would happen to aluminum’s conductivity if individual atoms were removed or rearranged. Even small changes can boost conductivity. The computer models proved themselves well-suited to simulate real-world conditions. Having settled on a recipe to boost the conductivity of aluminum, researchers will now test the theory in the laboratory. Aluminum alloys made using additives such as graphene or carbon nanotubes can also provide properties material that pushes the metal past its theoretical limit of conductivity. Solid-phase manufacturing enables the layering of new carbon materials into the metal to improve conductivity. Conductivity testing Producing wires out of the alloys will allow researchers to test conductivity. Then creating bars and sheets will enable testing to determine if the material is strong and flexible enough to be used for industrial applications. If testing is successful, researchers will work with manufacturers to produce higher amounts of the alloy. The research comes at an opportune time: The price of copper has spiked, and analysts project a shortage. Green energy transition The availability of more conductive aluminum will open a wider range of electrical applications The transition to green energy will increase the demand for conductive materials in applications like offshore wind farms. An electric vehicle uses about four times as much copper as a conventional car. Aluminum is already used for high-voltage power transmission because it is lightweight and inexpensive. However, the current applications for aluminum are limited by its lower power conductivity compared to copper. The availability of more conductive aluminum will open a wider range of electrical applications. ultra-conductive aluminum applications In the end, ultra-conductive aluminum would be useful as an alternative to copper in transmission lines, vehicles, electronics, and the power grid. Founded in 1965, PNNL is operated by Battelle for the Department of Energy’s Office of Science, which is the largest supporter of basic research in the physical sciences in the United States.

Located on the Red Sea coast of Saudi Arabia, Yanbu is the nerve center of the Kingdom’s petrochemicals industry. One of Yanbu’s critical installations is the power station, which has several Gas Turbine Generators (GTGs) with a total capacity of 524.6MW. The power station caters to the region’s total electricity demand. DG sets In case of any unexpected shutdown, the GTGs are restarted by DG sets designed specifically for Black Start applications. The DG sets are supplied by Saudi Diesel Equipment Co. Ltd., a well-known local manufacturer, and supplier to the oil and gas industry since 1978s. The new DG sets are supplied to replace a 35 years-old existing DG sets based on a detailed assessment by the company responsible for the maintenance of the power station. Entrusted with the task, Saudi Diesel opted for alternators from Nidec Leroy- Somer, its trusted supplier. DOL starter motors Given the critical nature of the project, the company ordered two DG sets for redundancy and reliability The GTGs are equipped with DOL starter motors of 600kW, 4.16kV rating, and the starting current is very high, 6 times the nominal current which means there is a huge inrush current experienced by the alternator. Given the critical nature of the project, the company ordered two DG sets for redundancy, and thereby, reliability. Black Start The DG set first acts as a Black Start and is primarily responsible to start the turbines that are down or under planned maintenance shutdown. The DG set is also used to feed auxiliary loads in case the need arises for emergency loads other than the turbine load, before or after the Black Start, till such time the turbines take over the full load. Challenge For Nidec Leroy- Somer, the challenge was to design a medium voltage 4.16kV alternator with a rated power of 4000kVA. This is a high-speed alternator, IP23 rated, so there were some constraints regarding the design of the machine. An important consideration was adapting the design to the ambient temperature of 50°C with the humidity reaching 100% in consideration of the very harsh environment at the site. D550 digital AVR AVR has functionalities including online monitoring with manual and remote controls Nidec Leroy- Somer also used the latest D550 digital AVR, which is ideal for parallel genset operation. The AVR also has a wide range of functionalities including online monitoring with manual and remote controls. The two alternators were designed and manufactured after a thorough calculation of all electrical parameters following detailed discussions with the client before finalizing the design. Once assembled, the alternators were tested and approved by Saudi Diesel along with third-party inspectors, a prerequisite for any machine exported to Saudi Arabia. synchronous speed “Any application that involves a power plant is very critical, because in case of a shutdown, the unit has to restart and come online as fast as possible, and these are very heavy turbines, each of 50MW. Also, they must run to a synchronous speed before energizing the equipment and connecting to the grid. That is the critical part, getting the GTGs into a synchronous speed before connecting to the grid,” says Nawar Shubber, Regional Sales Manager at Nidec Leroy-Somer. complete packaged units The two DG sets were supplied as complete packaged units, each measuring 13mtr (L) x 5mtr (W) x 6 meters (H) in dimensions. The diesel engine is from MTU, Germany. Each package is a complete unit with the Engine coupled to the Alternator, Diesel Tank, MV Switchgear, 480V Motor Control Center (MCC), Control Panel, Fire Alarm, Suppression System, and Radiator Cooling System. axial up-blast fans Two axial up-blast fans have been installed for ventilation purposes during operation to maintain the temperature rise inside the enclosure within 5-degC. The ingress protection rating during standby time for the whole package is IP56. The packages are based on a plug-and-play concept easy to install, easy to run, and easy to maintain. gas-tight enclosure Enclosures for the entire generator set, fabricated locally, contain UL-motorized louvers" “Enclosures for the entire generator set, fabricated locally, contain UL- motorized louvers for totally enclosed operation during shut-down. The package is designed as a gas-tight enclosure while the fire alarm and suppression systems in these units are tested by NFPA 2001 and BS EN 15004-1,” says Kathim Alrifai, Project Manager at Saudi Diesel Equipment Company. generator Apart from the harsh environment, the project is also located within a high seismic zone. The generator is mounted on dual spring and rubber vibration isolators designed to withstand earthquakes and seismic activity within specific limits, as determined by the data applicable to the city.
