Energy Efficiency

On January 20, 2022, the first converter valve of the China Great Bay Area DC back-to-back project was successfully put into operation for the first time, marking an important step forward for the interconnection of the core areas of the Eastern and Western Pearl River Delta of the Guangdong power grid. The converter valves were supplied by NR. Unit 1 on the East side of Guangzhou took the lead in entering the system commissioning stage among the four units of the whole project, creating a new record of successful operation and "zero" sub-module failure, thanks to various innovations and efforts. Safety and reliability of the sub-module In the design, the iterative upgrading to improve the reliability is made on the primary design and secondary board, which effectively ensures the safety and reliability of the sub-module. In terms of test methods, two non-invasive whole tower test methods have been pioneered. One is the valve tower rapid test technology, which can compress the test time of a single tower by at least 5 times, and maintain the integrity of the secondary circuit and optical fiber circuit of the sub module in the whole process. Communication status data of submodules Two technologies greatly improve the test efficiency and reliability of the converter valve subsystem The second is the communication on-line monitoring technology, which obtains the communication status data of submodules in real time. The two technologies greatly improve the test efficiency and reliability of the converter valve subsystem, and lay a foundation for the success of the one-time operation of the converter valve. Through technological innovation, NR assisted the owner to complete the set objectives with high quality and quantity under the condition of tight deadlines. It took only 45 days from the installation of the converter valve to the commissioning of the system. Scientific and technological innovation The DC back-to-back project of Guangdong power grid will strengthen the power supply guarantee of the China Great Bay Area. At the same time, it also has important functions in fault isolation, emergency power support, power exchange, and so on. NR will continue to practice the corporate purpose of "creating value and serving society" through scientific and technological innovation, and providing customers with high-quality products, solutions & services.

Luxi Island microgrid system, which was designed, supplied, commissioned and delivered by NR, has been successfully put into operation. The system effectively solved the black start problem of 10kV feeder level microgrid with impulsive load, and has won high recognition from users with an advanced and intelligent control strategy, a stable and reliable microgrid system. Power supply of Luxi Island The power supply of Luxi Island was transmitted remotely by submarine cables Luxi Island is located on the east coast of China. The power supply of Luxi Island was transmitted remotely by submarine cables, which was easy to cause power supply interruption due to cable and tower damage. Due to the weak load carrying capacity of the original microgrid system, complex black start steps, difficult operation and low success rate, once the power was cut off, the recovery time was long, which seriously affects the production and life of residents on the island. Microgrid energy management system NR provides microgrid integrated solutions, including a microgrid energy management system, a microgrid coordination controller, an energy storage converter, and other core equipment, which effectively solves the existing problems. A microgrid system was required to quickly restore power supply after a power loss of the large power grid, and the black start function was the most important means to restore power supply and an important guarantee for the stable operation of the system. 10kV distribution network feeders usually have a large number of T-connected transformers, large load capacity. Research of microgrid technology NR successfully realized the black start function under the condition of full input of 10kV The simultaneous start of transformer inrush current and a large number of motor loads was easy lead to black start failure. The automation level of the existing distribution network system was low, relying on the manual opening and closing switch of the operation and maintenance personnel, and the power failure time of the system was long.  In view of these problems, based on the long-term accumulation in the research of microgrid technology, NR successfully realized the black start function under the condition of full input of 10kV feeder load through intelligent one-key black start control and flexible synchronous parallel start technology of multiple converters. Technical advantages of NR The whole process took less than 10s from the issuance of command to the stable establishment of bus voltage, and quickly realized power supply restoration of 18  transformers, 1359 resident users and 177 non-resident users. The power supply reliability of Luxi Island has been significantly improved. The successful implementation of the project has further consolidated the technical advantages of NR in the field of microgrid, and provided the solution for the local autonomy of the new distribution system with high distributed energy resource penetration. NR will continue to practice the corporate purpose of "creating value and serving society", and contribute more to the development of a reliable green power system.

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 skilled trades industry stands out as a resilient sector, offering the next generation of workers a promising path for growth and professional development through on-the-job experience and education. Significant talent gap With the retirement of Baby Boomers leading to a significant talent gap, current trade professionals are now more determined than ever to attract younger workers to the industry.  Regrettably, many students in high school fail to see the value of pursuing a career in skilled trades. In a 2022 survey, only 16% of students noted they were likely to consider a career in the skilled trades. However, as other industries face a high level of uncertainty, the skilled trades offer stability and constant demand for services such as new construction, renovations, and climate change-resilient building improvements. The Benefit of Trade Education One of the major benefits of skilled trades education is its flexibility and room for career advancement The skilled trades industry presents young professionals with unique opportunities for hands-on learning and digital skill development. And as the next generation begins to explore higher education alternatives to gain valuable life skills, hands-on training in skilled trades becomes increasingly appealing. In trade education, learning happens directly from experiences in the field, complemented by classroom training, on-demand video sessions, and even virtual reality (VR) simulations. This approach ensures that graduates are well-prepared to start their careers immediately, avoiding the burden of college debt. One of the major benefits of skilled trades education is its flexibility and room for career advancement. Unlike traditional four-year college programs, trade school education typically lasts around two years, making it accessible to individuals at different stages of their careers. Moreover, the skilled trades industry provides workers with continuous opportunities for education and specialization. Formal certifications or licensing requirements define career paths in the skilled trades, and workers can pursue additional certifications to open new avenues for advancement. Beyond Traditional Training Techniques To maintain its resilience, the skilled trades industry is embracing technology To maintain its resilience, the skilled trades industry is embracing technology, integrating tech-focused learning methods and digital platforms to streamline processes and increase efficiency.

Even during the era of big business, most residential electrical service companies tend to be on the smaller end with less than 20% employing more than 100 workers. And, like most small businesses, electrical contractors probably assume that they don’t need public relations and that their advertising efforts are enough to sustain them. But this is a common misconception. PR isn’t a luxury reserved for million-dollar companies and can be used to help progressively scale your business in the long run. Lead generation companies If you’re like most electrical contractors, you are using the marketing and advertising advice that many other home service companies have taken over the years and have confined your advertising into avenues such as direct mail, lead generation companies, truck wraps and a reliance on third-party referral websites. That is one reason why adding PR to your marketing budget is a necessity While these are all good options, the problem is that your competition is also using the same marketing techniques you are using and are probably only reaching the same set of potential customers. That is one reason why adding PR to your marketing budget is a necessity if you want to rise above your peers in your market. Residential electrical services If you were to do a quick Google search for electrical contractors in your community, chances are you’d find page after page of similar options. And, if you aren’t on the first page of that list, you aren’t making much of an impact. But, with the right PR partner, you can build your company’s reputation and recognition so that it becomes synonymous with good residential electrical services. A public relations expert can help you develop campaigns that show you as a thought leader in your market while helping you secure earned media in your local news and trade publications. A public relations expert can help you develop campaigns that show you as a thought leader These methods increase your visibility. Strong visibility not only helps you reach a wider audience, it inadvertently helps you move up spots in Google rankings. The more mentions your company gets on social media, in the news and on other online platforms, the better Google ranks your website. what is Earned media So what is earned media? That’s media that isn’t paid for or owned by your company and includes media interviews, customer reviews and organic mentions on social media. And, it’s important because it is by far the most trusted form of publicity available. Studies have shown that more than 90% of consumer trust earned media over paid-for advertising. Consumers have become savvy to commercials and no longer uses ads as their main method of researching a potential service partner. But, it’s getting this earned media that can prove tricky for most electrical contractors. Most of you probably don’t know any journalists and you certainly don’t have time with your busy schedule to cultivate relationships with the media. Potential service partner A good PR expert can pitch your expertise and story ideas surrounding your company That’s where a PR agency can help. Many of them are former reporters or know the business well enough to have built relationships with many media outlets. A good PR expert can pitch your expertise and story ideas surrounding your company to media both locally and in trade publications. It’s also possible that you haven’t considered the need to consistently read and respond to your customers’ reviews online. This is important because studies have shown that more than 92% of consumers say they read online reviews before they purchase a product or hire a service provider. Social media game Since you do have a business to run, it may be difficult to carve out enough time to reply to these reviews – both the good and bad ones – in a way that is both effective and conciliatory. But, a PR partner does have the time and the experience to do this for you. But, a PR partner does have the time and the experience to do this for you Finally, PR helps you stay on top of your social media game. It’s not enough to simply have a company Facebook or LinkedIn page – you have to consistently post content and engage your followers. Coming up with something new to post is a challenge when you’re trying to schedule house calls, pay bills and hire quality electricians. Attracting new customers Once you have developed a PR strategy that helps you to promote your brand, increase your visibility and develop you and your company as the market leaders in your community, you’ll begin to notice that your brand is reaching a wider audience. And, it’s a proactive strategy that will help you influence the market in your favor. These positive messages help you grab the attention of your target audience and connect with them on a personal level.

Electricians play a pivotal role in preventing electrical fires by following safe practices during installations, repairs, and inspections. At a minimum, electricians should ensure all electrical wiring and components are installed according to current building codes and manufacturers' specifications. This includes using the right size wires for the amperage load, using approved materials, and properly securing all connections. During electrical inspections, electricians should identify and address any potential fire hazards. Electricians can also advise homeowners on electrical safety measures they can take to prevent fires. These include safe appliance use, avoiding overloaded outlets, and the importance of smoke detectors and fire extinguishers. Maintenance of electrical systems Ground Fault Circuit Interrupters (GFCIs) can prevent possible fires. GFCI outlets have built-in protection to detect imbalances in electrical current and quickly shut off power to prevent shocks and potential fires, particularly in areas prone to moisture like kitchens and bathrooms. Regular maintenance of electrical systems is also crucial for fire prevention. Electricians can perform preventative maintenance checks to identify and address any developing issues before they become serious fire hazards. Fire departments responded to an average of 32,160 home fires involving electrical distribution Fire departments responded to an average of 32,160 home fires involving electrical distribution and lighting equipment each year in 2015–2019, according to the National Fire Protection Association (NFPA). Electrical fires cause scores of civilian deaths and hundreds of civilian injuries, as well as millions of dollars in property damage. Fire Hazards in the Home Some of the electrical components that present fire hazards in the home include faulty electrical outlets and switches, worn or damaged components, overloaded circuits, damaged or frayed cords, and misused extension cords and power strips. Improper use of light fixtures can also be a danger, and space heaters can be a fire hazard if they are placed too close to flammable materials or left unattended. Damaged or frayed cords can cause sparks and ignite nearby flammable materials As outlets and switches age, the wiring behind them can loosen and break, causing sparks and fire. Loose plugs can also overheat and ignite surrounding materials. Plugging too many appliances into a single outlet or using extension cords instead of proper wiring can overload a circuit, thus causing overheating and fires. Damaged or frayed cords can cause sparks and ignite nearby flammable materials. Cords that are kinked, pinched, or have exposed wires should be avoided and replaced immediately. Minimizing the Risk of Electrical Fires Here are some steps a homeowner can take to minimize the risk of fire from electrical systems: Upgrade the electrical system, especially if the home is older. If the electrical system has not been updated in a while, a qualified electrician can advise if it needs modernization. This could involve upgrading to breakers with better safety features such as Arc-Fault Circuit Interrupter (AFCI) and Ground Fault Circuit Interrupter (GFCI) technology. Schedule an electrical safety inspection. Having a qualified electrician periodically inspect a home's electrical system can identify potential problems before they escalate into fire hazards. Keep flammable materials away from electrical components, including curtains, furniture, and piles of paper. Sparks and overheating can easily ignite nearby flammables. Addressing Multiple Threats Effective communication is key for electricians to impress upon homeowners the seriousness of fire hazards. Avoid technical jargon and explain fire hazards in clear, concise language that homeowners can understand. Focus on the potential consequences, like damage to property or injury, to heighten awareness. Pictures can be worth a thousand words. Show homeowners examples of damaged wiring, overloaded outlets, or faulty installations that pose fire risks. This can be done through photos on a tablet or phone, or even carrying around small physical samples. Frame the conversation around safety for the homeowner and their family. Highlight how addressing these hazards can prevent potential fires and ensure a safe living environment. Provide a written report after the inspection or repair. This report should detail the identified hazards, the corrective actions taken, and any recommendations for future maintenance or upgrades. By combining clear communication, visual aids, and a focus on safety, electricians can effectively convey the importance of addressing fire hazards to homeowners and empower them to make informed decisions about their electrical systems.

Rising material prices and inflation, in general, are likely to continue to plague electricians and others in the trade service businesses, according to a new survey conducted by the business management software platform Simpro. In the survey, 20% of electrical respondents say they are more likely to face rising material prices this year, while 20% of owners, CEOs, and business managers in the broader category of trade service businesses are more likely to face inflation concerns. ongoing economic uncertainty Another big concern across all trade service businesses is staff retention. Even higher percentages of survey respondents expect continuing challenges presented by the labor market: 73% anticipate hiring to be more challenging in 2023 than last year because of a lack of skilled workers (cited by 51% of respondents) and ongoing economic uncertainty (cited by 50%). The survey, conducted in January 2023, also highlighted changes trade service companies saw in the market last year compared to 2021. Customer acquisition Customer acquisition was more challenging in 2022, according to 66% of survey respondents In a service-based industry, customer satisfaction is a high priority: 95% of trade professionals noted that customer experience is paramount, and 73% have adopted technology tools specifically designed to enhance the customer experience.  Customer acquisition was more challenging in 2022, according to 66% of survey respondents, while customer retention was more challenging for 60% of respondents.

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.

As part of a long-term modernization project at the Baltimore Washington International (BWI) Airport, Helios Electric was retained to perform design-assist, system integration, and on-site field engineering services.  The project involved replacing an existing 7.5/10.5 MVA outdoor substation transformer and performing retrofit services at the corresponding medium-voltage switchgear lineups.

Siemens has developed a digital twin especially for large event spaces. The technology makes it possible to realistically reproduce and simulate very precisely a building’s acoustics and structure. The Sound of Science application will be used for the first time in the Großes Festspielhaus – the Large Festival Hall – at the Salzburg Festival. Sound of Science application Orchestral formations on the stage can also be tested and arranged in advance Sound of Science will enable event organizers to virtually explore how acoustics change in different spatial configurations – for example, how adding acoustic panels affects the listening experience – in order to select the optimal acoustic scenario. Orchestral formations on the stage can also be tested and arranged in advance – before a single note is heard in the real world. This approach saves money, resources and time. Siemens to use digital twins “With Sound of Science, we’re designing the future. Digital twins are not only transforming the everyday for many companies, but are also creating new opportunities for the cultural and creative industries,” said Prof. Dr. Stephan Frucht, Artistic Director of the Siemens Arts Program. Dr. Stephan Frucht adds, “In the future, we’ll be able to plan stage productions better and even simulate them acoustically in advance. We’re delighted to have the Salzburg Festival at our side as a long-standing partner, who recognizes the opportunities such innovations offer.” Sound of Science app for select partners Siemens will make the Sound of Science app available to selected partners from the cultural world free of charge as a demonstration application. There are currently no plans to market the application. Its simulation solutions, however, may be purchased. The Salzburg Festival’s Großes Festspielhaus is the first and only large event space to date in which Sound of Science is available. However, Siemens is planning to digitally simulate further spaces – including concert halls in Germany and England. At the Salzburg Festival, audiences will have an opportunity – unique for the time being – to use VR glasses to experience the application at the festival’s opening on July 20. Siemens and the Salzburg Festival “Siemens and the Salzburg Festival share a common passion for excellence and innovation. And we’re delighted to partake in this pioneering technological development and innovation as part of our long-standing close and trust-based partnership,” said Dr. Kristina Hammer, President of the Salzburg Festival. Dr. Kristina Hammer adds, “We’re excited to see what diverse applications will stem from Sound of Science in the future.” Siemens Simcenter’s simulation solutions The technologies used are part of the simulation solutions from Siemens Simcenter The technologies used are part of the simulation solutions from Siemens Simcenter, which has been part of the company’s core business for over 15 years. The technology is mostly used in industry – for example, for the acoustic optimization of vehicle interiors or for protection against street noise. For Sound of Science, Simcenter uses a combination of impulse response measurements and ray tracing for the 3D modeling of each event space. These methods can measure the echo and reverberation of a sound and simulate how sound waves propagate in a room. Depending on the material, reflections of sound waves behave differently. Those that bounce off a concrete wall react differently from those that hit a carpet or reach the ear directly. As a result, the simulation can reproduce the individual sound signature of each event space – in other words, its acoustic DNA. Siemens Festival Nights Siemens has been working closely with the Salzburg Festival for around 30 years. Since 1999, the company has also been the festival’s main sponsor. Since 2002, the Siemens Festival Nights have been held on Kapitelplatz square during the Salzburg Festival. Since its beginning, this open-air event has provided more than one million visitors with the opportunity to experience previous and current festival productions on an LED screen free of charge. In addition, some of the Salzburg Festival’s venues are equipped with Siemens technology from the areas of building automation, security and acoustics.
