Power to the People: How Transactive Energy Systems Are Revolutionizing the Future of Electricity Part 1

Transactive energy systems (TES) represent a revolutionary shift in the way energy management is conducted, offering a platform for instantaneous, peer-to-peer energy exchanges between decentralized energy resources and end-users. Moving away from conventional, centralized systems, Transactive Energy leverages a decentralized approach where real-time, market-driven transactions are the norm.

This framework brings together a diverse array of stakeholders —including utilities, independent energy providers, and consumers—in a vibrant, interactive environment. The system is supported by cutting-edge technologies such as smart grids, instantaneous metering, data analytics, and blockchain, which collectively enable more efficient energy use, bolster grid stability, and cut costs.

Crucially, TES also makes it easier to incorporate renewable and decentralized energy sources into the grid. This innovation turns ordinary consumers into "prosumers"—engaged market players who not only consume but also produce, store, and potentially sell energy, either to the grid or directly to other users.


Setting the Stage: The Backstory

The traditional energy systems that have powered our lives for more than a century are increasingly showing their age and limitations. Designed for a one-way flow of electricity from large, centralized power plants to consumers, these systems lack the flexibility to meet the evolving demands of modern society. Their centralized nature makes them vulnerable to disruptions from natural disasters or equipment failure, and their inefficiency often results in wasted resources and environmental degradation.

Moreover, these systems were not built to accommodate the surge of renewable energy sources like wind and solar, which are crucial for combating climate change but introduce variability and distribution challenges.

To overcome these limitations, the concept of Transactive Energy Systems has emerged as a compelling alternative. Enabled by technological advancements in smart metering, real-time data analytics, and secure transaction platforms, TES introduced a decentralized, adaptive approach to energy management. Here, energy becomes a commodity that can be traded in real-time markets, allowing for dynamic pricing based on supply and demand. Consumers, no longer passive actors, become "prosumers" who can generate, store, and even sell energy back to the grid or to peers.

The transition from traditional to transactive systems is not just a technological shift; it's a fundamental reimagining of how energy systems can be more efficient, resilient, and democratic.


The Old Guard: Why Traditional Grids Can't Keep Up

Let’s take a deeper dive into traditional electrical grid systems. Traditional electrical grid systems, sometimes known as centralized or "top-down" systems, are designed around a one-way flow of electricity from large-scale power generation facilities to consumers. Here's an overview of how these systems are traditionally structured:

The Components of Traditional Grid Systems:

  1. Generation: Electricity is generated in large-scale power plants that may use fossil fuels (coal, natural gas), nuclear energy, or large hydroelectric dams. These facilities are usually located far from populated areas.
  2. Transmission: High-voltage transmission lines carry electricity over long distances from the generation plants to substations near populated areas. This involves a network of transmission towers and cables.
  3. Substations: These facilities step down the high-voltage electricity to lower voltage levels suitable for distribution to residential, commercial, and industrial users.
  4. Distribution: After the voltage is stepped down, electricity travels through a network of lower-voltage distribution lines, which may be above or below ground, to reach individual consumers.
  5. Consumers: Finally, electricity is delivered to homes, businesses, and industrial facilities, where it powers various types of electrical equipment and appliances.


Characteristics

The traditional electrical grid systems exhibit several defining characteristics that influence how energy is generated, transmitted, and consumed, ranging from centralized control and one-way energy flow to economic inefficiencies and environmental impact.

  1. Centralized Control: The grid is generally managed by a centralized utility or grid operator responsible for balancing supply and demand, scheduling maintenance, and managing outages.
  2. One-way Flow: Traditional grid systems are built for a one-way flow of electricity from the central power plants to consumers. They are not designed for consumers to send excess electricity back to the grid easily.
  3. Limited Flexibility: These systems are often not well-equipped to handle fluctuations in supply and demand or to incorporate distributed renewable energy sources like residential solar panels.
  4. Low Resilience: The centralized nature of the grid makes it vulnerable to disruptions (e.g., natural disasters, equipment failure) that can affect large numbers of consumers.
  5. Economic Inefficiencies: Since the grid has to be built to handle peak demand, much of its capacity may go unused during periods of low demand.
  6. Environmental Impact: Centralized power generation, especially those reliant on fossil fuels, contribute to greenhouse gas emissions and other environmental concerns.
  7. Regulatory Framework: Usually governed by a mix of local, state, and federal regulations, including rate-setting by public utility commissions.
  8. Limited Customer Interaction: In traditional settings, consumers are usually passive participants who have little control or choice over their electricity sources or usage patterns.

Traditional grid systems have been the backbone of electricity supply for over a century, but they face growing challenges in the context of modern energy needs, including environmental sustainability, resilience against failures, and integrating new, decentralized energy sources. This has led to increasing interest in more flexible and adaptive alternatives like Transactive Energy Systems.


Revolution in the Making: What's Fueling the Rise of TES?

While traditional grid systems have served us well for many years, they come with their own set of limitations and inefficiencies. In contrast, the advent of Transactive Energy Systems (TES) is ushering in a new era of energy management, motivated by a variety of driving forces such as technological advancements, economic considerations, environmental concerns, and social factors.

By harnessing cutting-edge technologies like smart grids, blockchain, and the Internet of Things (IoT), TES aim to completely transform the energy landscape, offering a more efficient, resilient, and sustainable alternative. Let's delve into the key factors driving the development of transactive energy systems:

  • The growth of distributed energy resources (DERs), such as solar panels and batteries. DERs can provide electricity to consumers directly, bypassing the traditional grid. This is challenging for grid operators to manage, as it can create imbalances between supply and demand. Transactive energy systems can help to manage these imbalances by allowing consumers to buy and sell energy from each other.
  • The need to integrate more renewable energy into the grid. Renewable energy sources, such as wind and solar, are intermittent, meaning that they do not always produce electricity when it is needed. Transactive energy systems can help to balance the grid by allowing consumers to reduce their energy use when renewable energy is abundant and increase their use when it is scarce.
  • The desire to improve energy efficiency and reduce costs. Transactive energy systems can incentivize consumers to use energy more efficiently by giving them the ability to sell their excess energy back to the grid or to other consumers. This can help to reduce the need for new power plants and transmission lines.
  • The need to improve grid resilience. Transactive energy systems can help to make the grid more resilient to outages and other disruptions by allowing consumers to provide backup power to each other.

In addition to these technical factors, there are also a number of social and economic factors driving the development of transactive energy systems. These include:

  • The growing demand for consumer choice and control. Consumers are increasingly demanding more control over their energy use and how they pay for it. Transactive energy systems can provide consumers with more choice and control by allowing them to participate in energy markets.
  • The need to reduce greenhouse gas emissions. Transactive energy systems can help to reduce greenhouse gas emissions by making it easier for consumers to adopt renewable energy and energy efficiency measures.
  • The emergence of new technologies. The development of new technologies, such as smart meters and blockchain, is making it possible to create more sophisticated and efficient transactive energy systems.

Overall, the driving factors for the development of transactive energy systems are complex and multifaceted. They include a combination of technical, social, and economic factors.

Solar Technology
Renewable Energy

The Latest Breakthroughs in Solar Technology

As the world increasingly looks for sustainable and environmentally friendly energy sources, solar technology has emerged as a key player in the shift towards renewable energy. Solar power is a clean, renewable, and abundant energy source that can be harnessed with the use of solar panels. The importance of solar technology lies in its ability to reduce dependence on fossil fuels, which are finite and contribute to climate change. Additionally, solar power can help to increase energy security and access in remote or underserved areas. In this context, the development and adoption of solar technology has become a crucial aspect of the global effort to combat climate change and promote sustainable development.

State of the Industry In 2023

The U.S. Energy Information Administration has announced that developers plan to add 29.1 GW of solar generating capacity to the U.S. grid in 2023, accounting for 54% of planned new capacity for the year. A total of 54.5 GW of capacity is expected to come online this year, with solar ahead of other sources. Renewable energy developers in Texas plan to add 7.7 GW of solar capacity to its grid, followed by California with 4.2 GW. However, the industry was impacted by supply constraints, inflation, and labor shortages in 2022, leading to delayed projects. The implementation of the Inflation Reduction Act and tax credits for solar production are expected to drive domestic supply and demand for solar components.

Three Solar Industry Trends to Watch for in 2023

1. Spotlight On California

It is clear that the changes to Net Energy Metering (NEM) policy in California will have a significant impact on the state’s residential solar industry, and the nation will be watching closely to see how the industry adapts. The immediate rush to install solar before the April deadline is expected, but the industry may suffer a significant drop in installation requests after that. Furthermore, the California Public Utilities Commission’s judgment that solar-plus-battery systems will rise in adoption as NEM is cut will be put to the test, and recent analysis suggests that this may not be the case. Other states will also likely face battles over NEM policy changes in 2023, indicating that this will continue to be a contentious issue in the solar industry.

2. Launch Of Inflation Reduction Act

It will be interesting to see how the Inflation Reduction Act of 2022 is implemented and what its impact will be on the solar and storage industry. The $369 billion set aside for climate and energy goals is a record amount, and the industry will need to sort out the finer details on how to meet the Act’s requirements to qualify for tax credit incentives and value adders. The White House has released a guidebook to help industry members navigate the complexities of the Act’s many offerings, and the Biden Administration is working with industry stakeholders to ensure the law is implemented effectively. The way the law is interpreted and implemented will be watched closely in 2023 to determine its final impact, and companies like Enphase Energy are already making plans based on their interpretation of the Production Tax Credit (PTC). Enphase CEO Badri Kothandaraman has said that the company will only make a significant investment in U.S. manufacturing if it can secure a significant return on investment and retain 50% or more of the PTC’s value. Overall, the solar and storage industry is poised to create hundreds of thousands of new jobs and build out the next era of American energy leadership, but the success of the Inflation Reduction Act will depend on how effectively it is implemented and how it is interpreted by the industry.

3. Module Supply

The solar industry faced several challenges in 2022, including a lack of steady supply of modules and solar components due to COVID-19 related delays, increased commodity and shipping costs, and the threat of tariff implementation. The Uyghur Forced Labor Prevention Act (UFLPA) also added to the industry’s headwinds, with the act placing a “rebuttable presumption” that goods from the Xinjiang region of China are made with forced labor, and placing the burden of proof on buyers to show that the imported goods have no connection to forced labor. While some of these headwinds are calming in early 2023, it remains unclear how much of an effect the UFLPA will have on the ability of components to pass U.S. Customs and enter the market. Customs has cleared a meaningful supply of JinkoSolar modules made with Wacker polysilicon for the U.S. market, but there is still a significant backlog of modules remaining to be cleared. The lack of clarity on exactly how UFLPA and anti-circumvention tariffs will be implemented makes this another major story to watch in 2023.

The State of Solar Technology

As of 2023, solar technology has continued to advance and become more efficient, affordable, and widely used. Here are some key developments:

More efficient solar panels

Solar panel technology has improved significantly over the past few years, with newer panels having higher efficiency levels than older ones. The latest solar panels have efficiencies of over 25%, compared to around 20% just a few years ago. This means that they can convert more of the sun’s energy into electricity, making them more cost-effective.

Energy storage solutions

Advances in energy storage technology have made it easier to store excess solar energy generated during the day for use during the night or on cloudy days. This has helped to increase the reliability and stability of solar power systems, making them more attractive to consumers and businesses.

Solar-powered transportation

Solar-powered electric vehicles and charging stations have become increasingly common, helping to reduce greenhouse gas emissions and promote clean energy. Some companies are even developing solar-powered airplanes and boats, which could revolutionize transportation in the future.

Building-integrated photovoltaics

Building-integrated photovoltaics (BIPV) are solar panels that are incorporated into the design of buildings, such as roofs, windows, and facades. BIPV systems are becoming more popular, as they can provide both energy and aesthetic benefits to buildings.

Smart grids and energy management systems

Smart grids and energy management systems are being developed to help integrate solar power into existing energy systems. These technologies allow for more efficient distribution of energy, reducing waste and costs.

A Promising Outlook for Solar Technology

Solar technology has become an increasingly important player in the global shift towards renewable and sustainable energy. It has also made significant progress in recent years, and it is expected to continue to grow in popularity and importance as the world transitions towards cleaner, renewable energy sources. With the U.S. expected to add 29.1 GW of solar generating capacity to the grid in 2023, the industry is poised for significant growth, although supply constraints, inflation, and labor shortages may pose challenges. Despite these, solar technology continues to advance and become more efficient, affordable, and widely used. The success of the solar industry and its ability to combat climate change and promote sustainable development depends on continued innovation, investment, and collaboration between industry, government, and society as a whole.

Energy Solutions Search Continue
Renewable Energy

It’s 2022, and the Search for Energy Solutions Continues

Sustainable and reliable energy solutions are paramount to modern technological advances. Though there have been breakthroughs, things are still not quite at the level technologists and businesses have expected. Still, there are notable developments in the public and private sectors.


The Stakes

Exponential technological advancements, combined with breakthroughs like those related to quantum computing, will revitalize the industry. Given the public and private sector advancement, however, how this will happen is yet undetermined.

There are multiple areas of innovation to watch in 2022. We’ll cover a few energy solutions that may soon be the go-to not just for individual use, but also for industrial implementation. These include:

  • Sodium (Na) Ion Batteries
  • Batteries of the “Solid State” Variety
  • Advances Owing to Electrical Vehicles
  • Graphene as an Energy Storage Option
  • Flexible “Thin Film” Printed Batteries
  • Electrolyte Storage Through Redox Flow Batteries
  • Lithium-Ion and an Increase in Demand, Plus Recycling
  • Gravitational Batteries, Cryogenic Air Storage, and “Green Hydrogen”


Sodium (Na) Ion Batteries

Sodium-Ion batteries (Na-ion) show substantial promise and work similarly to lithium-ion (Li-ion) batteries. They have slightly more power and cycle capability. Unfortunately, cathodes utilize nickel and cobalt, so Na-ion batteries are not quite as sustainable as many would like.


Batteries of the “Solid State” Variety

We’ll discuss electric vehicles in greater detail shortly. First, let’s look at “solid-state” batteries.

Chemical improvements include an anode of lithium metal that expands energy density, subsequently expanding performance capabilities. As yet, mass production isn’t streamlined, though the process is picking up steam. There is available research in this field as regards solid-state batteries.


Advances Owing to Electrical Vehicles

There’s a bright spot for electric vehicles (EVs). EVs need to store substantial quantities of energy that can be used in conjunction with varying features.

Without efficient energy storage, vehicles like Elon Musk’s Tesla wouldn’t be viable. Since present options are not yet optimal, companies are continuously seeking more efficient means of energy storage, changing the industry.


Graphene as an Energy Storage Option

For a while, graphene was touted as the solution that would overcome this energy issue. In 2004, graphene was discovered as a sort of energy “source” for batteries. In laboratory conditions, graphene has yielded notable results that the market still has not realized.

Basically, graphene derives from graphite (what’s used in pencils). Graphite is a 3D arrangement of atoms, graphene being that arrangement in 2D. Only an atom in thickness, graphene is over a hundred times stronger than steel–just two layers is effectively “bulletproof”. Its close atomic structure makes it a fine electrical conductor. The link in this section goes over these things in detail.

Here’s the bottom line: As of 2020, Real Graphene USA managed to design a graphene battery. A graphene battery used in a smartphone would charge in about half the time a Li-ion battery would. Is it safe? Real Graphene USA says it is.


Flexible “Thin Film” Printed Batteries

Printed batteries have been an exceptionally popular energy storage option, and some are already used in specific applications. The issue is about a more universal application of this storage innovation. Competition grows throughout the industry, There’s a full report about this.


Electrolyte Storage Through Redox Flow Batteries

Electrolytes are used to store energy in Redox Flow Batteries (RFBs). Because electrolyte storage is separated from the electrochemical cell in the unit, these batteries are ideal for long-term storage needs where they rest dormant.

Vanadium is the expensive key element involved in RFBs. That said, there exist less costly all-iron-based options. RFB designs are improving continually. Also, organic compounds can be used as electrolyte storage. The potential is there; the solidification of a balanced solution has yet to be finalized.


Lithium-Ion and an Increase in Demand, Plus Recycling

Because Li-ion batteries are very efficient, there’s quite a high demand for them. That demand is forecast to expand. The issue is, these batteries require lithium mining, which tends to be bad for the environment. Still, since they’re used in electric cars, expect demand to continue and possibly increase as EVs become more mainstream.

While Li-ion sustainability isn’t quite the same as that of “fossil fuels”, it’s still not a perfect option due to the mining issue. Li-ion recycling is picking up steam to facilitate greater sustainability overall. Basically, End Of Life (EOL) batteries can be refined and reused. This reduces the total burden despite being a less than ideal solution.


Gravitational Batteries, Cryogenic Air Storage, and “Green Hydrogen”

Other relevant options have no electrochemical elements at all. For example, gravity batteries use the force of gravity to generate energy. You can find some on the market right now that work like cuckoo clocks. Just reset the “weight”. Still, there are serious drawbacks to gravitational batteries and, except in niche applications, they’re not quite viable.

Compressed air energy storage using cryogenic techniques involving liquid oxygen has some applications. “Green hydrogen” promises to work well for long-term storage needs. Basically, hydrogen is produced from water and stored for later. The issue lies in the feasibility of storing flammable hydrogen.


The Future of Energy Storage

The overall outlook for energy solutions as regards storage is bright. However, no current solution outpaces traditional Li-ion options for now.

In spite of this, notable prospects are more viable than ever. Keeping pace with developments will help your business onboard the most sustainable options that become available.

5G technology is setting the stage for every regular city to transform into a “smart city.” 5G will provide the essential services cities need to function with the utmost efficiency. Cities of all sizes will smarten up in the years ahead, regardless of whether they are small, midsize, or large.


The Transition to Smart Cities is Finally Here

Smart cities are those that rely on local government, local organizations, and businesses to function in a high-tech manner with impressive efficiency. An entire network of technologies boosts the sustainability and livability of smart cities. The collection of data pertaining to weather, the use of utilities, energy, etc. sets the stage for cities to become smarter as time progresses. This data is analyzed to improve city services and ultimately enhance quality of life.

5G mobile networks are capable of enduring potential disruptions, ultimately ensuring requirements for bandwidth, latency and reliability will be accessible for a wide array of services. This takes place on the same network through a process known as ‘network slicing’.

5G technology makes it that much easier to enhance performance along with the ability to virtually slice the network to ensure the optimal performance for a wide array of applications. This virtual partitioning is performed by mobile network operators. If a portion is down or overloaded, it will still be possible to manage certain segments independently. This strategic approach permits use cases with specific requirements for latency, security, and performance to be present on the same network. Furthermore, this approach is optimal as it enhances flexibility, empowering network operators to meet service needs as time progresses, including those not yet available in 2021. This means the stage is set for the tech to be flexible to the point that it meets service needs that have not yet been created.


The Importance of Network Slicing

Operators are now capable of enabling services for specific use cases through rightsizing mobile connectivity for each such case with several virtual networks. Each slice can be customized to the required network performance for each case. Everything from duration to security, latency, coverage, and capacity can be accounted for.

As an example, consider an emergency responder network with complex tools for communications that make it easier for responders to coordinate highly effective and timely rescues when emergencies arise. If a devastating event occurs and the city residents transmit video, pictures, and text on social media in unison, the operators of the mobile network would still be able to provide the emergency responder crew with connectivity since their network slice will not get bogged down with any public traffic.


Network Functionality

As cities become more connected and smarter, network operators will be tasked with ensuring those networks are able to meet the needs of smart city residents. SDN, meaning software-defined networking, along with network function virtualization (NFV) are essential to such virtualization. 5G will prove adaptable and even programmable from one end to the next with the use of virtual constructs. SDN is centered on physical network infrastructure abstraction that sets the stage for network actions to be altered in accordance with guaranteed service performance for specific use cases.

NFV makes it easy for network function deployment and implementation through software as opposed to purchasing, shipping, and adding actual appliances. NFV executes a wide array of virtual network functions that are not tied to a specific location. In short, if a disaster occurs, there will still be 5G mobile network accessibility for emergency responders in spite of the fact that the use of these networks often go down when civilian use increases unexpectedly.


The Smart City Age Is Not Far Away

5G’s sliced networks really do make it that much easier for operators to provide optimal data speed, network connectivity, and subsequent reliability. Your city will likely transform into a smart city within a couple of years. Even small and midsize cities will make this high-tech transition that ultimately improves quality of life for everyone.

How 5G and Supply Chain Logistics Are Converging

Mixing 5G and supply chain logistics is a steadily growing strategy for industrial facilities and many other types of businesses. Hospitals, utilities, and manufacturing plants need massive bandwidth to handle the big data coming from IoT sensors. Embracing 5G is leading to faster and more reliable networking with minimal disruptions.

There are some barriers to adoption, though. One of the main reasons some manufacturers and their suppliers will be hesitant to invest in 5G is the cost. Another challenge is the learning curve that employees must face. For more established organizations, the question will simply be how much new digital technology to invest in beyond 5G, which encompasses artificial intelligence and machine learning.

However, while these barriers do exist, the benefits of 5G can far outweigh any challenges for its adoption. Here are a few reasons why suppliers are investing in 5G.


A Solution for System Streamlining

Businesses of any size can adopt 5G and supply chain digitization in a move toward greater efficiency and productivity. Companies that still use manual controls to monitor products and processes will face tough challenges against competitors that embrace digital transformation.

One of the advantages that a more digitized operation can have over more conventional operations is automation, which allows organizations to get more work with higher accuracy in less time than one person or sometimes even an entire staff. Another way this modern networking technology can streamline your operation is by generating a wealth of valuable data for you or machine learning software to analyze.


More Organized Warehousing

Warehouses are filled with IoT sensors so that a specific product - out of thousands - can be tracked and found instantly. Due to the expanding collection of data, 5G is a very sensible solution to handle the higher volume of data transmission.

Traditionally, all kinds of products got lost or damaged in storage somehow. But now, thanks to broader and more powerful connectivity, it's possible to monitor a product every second of its journey, from the manufacturer through the supply chain. Managers can now, for example, pinpoint exactly where and when something bad happened to a shipped item.


Real-Time Fleet Management

Fleet management can also be streamlined with 5G, as it allows headquarters to stay connected with each company vehicle at all times. This real-time management capability tracks location, gas mileage, tire pressure, and many other factors that affect vehicle performance. Collection of this massive amount of data on a daily basis is also much more efficient with the wider and faster bandwidth provided by 5G.

The more trucks a company has in its fleet, the more they need 5G to accommodate the high-volume data transmission. This technology is particularly ideal for a courier service comprised of independent drivers.


Conclusion

You will no doubt hear more and more about 5G and supply chain logistics transformation as the 2020s unfold. It will help businesses of all kinds manage a much larger pool of data than they currently handle. Consumers are embracing 5G as well since it will allow them to monitor deliveries more accurately and at any time.

Building Sustainability into Infrastructure with 5G and Energy Alternatives

Everywhere you turn, there are predictions about the future. But speculation itself is often a business that sells possibilities, rather than truth.

Meanwhile, news about 5G and energy alternatives beyond fossil fuels has been relatively quiet until the pandemic, despite years of technological innovation.

Here's how 5G and renewable energy are part of a broader digital transformation toward a more sustainable future.


Why 5G Is a Green Solution

The link between 5G and energy is an enabling effect on multiple social and economic processes. It strengthens and interconnects not only city infrastructure, but other realms as well. This includes healthcare systems moving toward telehealth, tourism adopting virtual reality, and remote work via the cloud across several industries. The more an operation cuts waste in its production processes, the more opportunity it has to contribute to greater economic and environmental sustainability.

Transportation companies, for example, can now monitor entire fleets over wireless connections as 5G allows for faster and broader data transmission coverage. It allows data to travel more seamlessly without delays that occur sometimes in 4G packet transfers. With the ability to operate fleets more efficiently, transportation companies can better manage its use of vehicles, and essentially, reduce fossil fuel emissions. Additionally, autonomous vehicles and delivery drones, that are dialed into a virtual private network, opens the door for safer and more efficient transport of products and materials.

Managers can also use real-time data on system performance to make technical or production adjustments when necessary. If a manufacturer discovers dangerous chemicals at its complex, for example, IoT sensors can detect the chemical data, then machine learning software provides recommendations on cleaning up the mess. This seamless access to system alerts can help businesses achieve their sustainability goals, as the new technology cuts greenhouse emissions due to its streamlining effect.


Energy Benefits of 5G and ICT

Renewable energy adoption is no longer characterized as uncertain; it's simply happening across residential, commercial, industrial, and government sectors.

IoT Energy Harvesting Options and Their Advantages

Modern developments in low-power equipment, such as smartphones and energy efficiency technologies, are paving the way toward a more sustainable and mobile society driven by IoT energy harvesting. This concept involves the accumulation, storage, and use of electric power monitored by IoT devices. Here's a look at how wireless communication and alternative energy are transforming mobile energy choices.


Energy Harvesting Technology

The use of IoT energy harvesting by electric utilities is growing every year, since it has proven to make operations much more efficient. Utilities have saved millions of dollars on cutting energy waste by covering operations with sensors that collect data on equipment and energy. Thanks to machine learning technology, when a power company has a power deficiency, IoT sensors can trigger an automated shift to tap stored energy from renewable sources.

Thousands of IoT sensors are being installed in remote locations to track a wide range of metrics on energy use. Transporting batteries or other forms of portable power from one location to another can be tracked to factor the carbon footprint generated from the journey. Energy harvesting to power wearables and other mobile devices might be derived from sources such as solar, wind, thermal and kinetic energy.


5 Powerful IoT Energy-Harvesting Options

  1. Solar Energy - Sunlight creates unlimited energy in certain geographic regions. But even in climates with limited sunshine, solar power can be an option. The sun is expected to shine for billions more years and every day it provides the earth with years’ worth of free energy. And thanks to a wealth of IoT data, scientists are constantly learning about new ways to harness energy from the sun.
  2. Thermoelectric Energy - Portable generators are used by people who enjoy the great outdoors, but so far, green choices have been limited. New innovations have made it possible for a thermoelectric generator to charge small IoT devices. The charge is activated by body heat or other environmental elements.
  3. Wind Energy with a Side of Solar - It's now possible to design a platform that harvests energy from both the sun and wind. This technology was recently announced by the National Center for Nanoscience and Technology in Beijing. The new product is called a Hybridized Nanogenerator and is positioned to integrate with smart cities for providing renewable energy. The solar element generates eight megawatts of electric power, which can convert wind into electricity.

Decentralizing Utilities with Renewable Energy & DERs

There's a growing awareness in the business community about the need for decentralized renewable energy. Distributed energy resources (DERs) are devices connected to the traditional grid that bring in energy from remote sources. A new energy paradigm is emerging that brings major improvements to existing power plants. Instead of a utility generating all of its own power to distribute to a community, multiple decentralized energy sources can now contribute to a central power distribution system.

Pressure is growing from communities for manufacturers and other big operators to reduce pollution and waste. Adding IoT systems and distributed energy resources to a power generation system helps prevent wasted energy and reduces greenhouse gases. DERs such as solar and wind installations are placed near loads and don't require long power lines. Here's a look at how this new paradigm is helping utilities strengthen their business models.


What Is Distributed Generation?

In the future, the traditional power grid will seem ancient, as it will be reimagined to utilize distributed energy, which is community-generated power that feeds into the main electric distribution grid. The DER concept is part of a broader sustainability plan since it provides renewable energy and uses IoT sensors to avoid energy losses. Solar and wind installations work well for this emerging decentralized solution that creates two-way energy flows for utilities.

Sometimes, power imbalances occur between the transmission and distribution grid operators. Reserves must be balanced and power generation should be stable for a utility to run at a level of high efficiency. The ability to access stored energy from various sources creates a more sustainable system that no longer has to rely on one main energy source.


How DER Disrupts the Power Industry

While DER is turning utilities into more efficient operations, it's raising the bar for consumer expectations about electricity reliability in the future. Using renewables to supplement the grid will help resolve the power gaps that can occur during peak demand periods. But in order for the whole nation to benefit from DER, every energy provider in the grid system needs to participate in the transformation toward smart technology and adoption of renewables.


DER Orchestration Considerations

  • Modeling - The utility can be analyzed using a model known as a network digital twin that replicates a business's entire operation in a virtual environment. Analysis of the model can lead to more accurate electrical connectivity and optimize the use of DER digital and virtual assets.
  • Interconnectivity - With a DER orchestration, all components must be interconnected with the ability to communicate with each other. Operators of transmission and distribution facilities need to evaluate various types of DERs to decide what type of equipment will be compatible with their system.
  • Predicting Energy Performance – Distributed energy systems can be integrated with machine learning software that predicts power shortages and when to tap into renewables as supplemental energy. Analysis of both real-time data and historical data can generate recommendations for power solutions. The system can also be programmed to automatically draw power from backup renewables when voltage suddenly drops.
  • Controlling and Scheduling - DERs can present challenges in controlling and scheduling issues that conflict between transmission and distribution operators. DER orchestration needs to be flexible so that renewable resources can be distributed effectively to serve prosumers, aggregators, and grid operators.


Conclusion

Renewable energy is already playing a major role in the transformation of utilities to become more efficient with lower costs and more reliable output. Solar and wind systems have contributed to the rise in DER adoption among utilities in which energy is generated by various providers in a community. The old-fashioned, one-way, one-size-fits all power generation model of the past is eroding in favor of decentralized power solutions that will help utilities achieve greater sustainability.

A Look at The Unstoppable Growth of Renewable Technologies

The rise of renewable technologies globally is worth strong consideration for utilities and other businesses that want to cut costs and greenhouse gases. Solar and wind renewables hit 10% of global energy sources in 2020, which is double the output of five years earlier.

With a third of its energy resources coming from renewables, the E.U. has been leading the way. And in the U.S., the use of renewables has risen to 10%.

The term "renewables" specifically refers to solar, wind, biofuels, geothermal and hydropower, among others. In the past decade, renewables have been the only category of energy that has experienced double-digit growth globally. In 2009, 8.2 exajoules of renewable were consumed, and that number quadrupled to 29.0 exajoules in 2019.


Analysis of Renewable Energy Industry Trends

The development of renewable technologies that deliver clean and sustainable energy is one of the most watched trends amongst the investment community.

Here are the types of the clean energy sources that are gaining the most momentum:

  • Solar - Solar photovoltaic (PV) energy is a fast-growing form of renewable energy, although hydropower currently still tops the list. In terms of "levelized cost of energy" (LCOE), hydro is still more cost-effective, but the declining price of solar panels is making the biggest waves with investors.
  • Thanks to government subsidies, solar PV is more cost-effective than fossil fuel power in certain countries. Output of solar power by utility plants began to skyrocket in 2016 from 7,501 to 14,762 MW. Meanwhile, residential and commercial solar have steadily grown since federal tax credits and subsidies were initiated by Congress in the mid-2000s.
  • Wind - Windmills are in the same league of LCOEs as solar and hydro. Wind power actually represents the top source of new energy used by utilities, according to the American Wind Energy Association (AWEA) in 2019. Onshore wind sources have the potential to reach 100 GW of electric output in the coming decade.
  • Biopower - Also known as "biomass energy", this growing and flexible form of renewables includes ethanol, biodiesel, and recycled wood. This sector of renewables, however, has not seen as much growth as solar and wind but still ranks third in terms of investment capital. Nearly half of all biomass energy consumption comes from wood and wood waste, such as pulp and paper. Production of ethanol in the U.S. is expected to reach 40 million gallons per day by 2050.
  • Geothermal - Although it was discovered thousands of years ago, this type of renewable energy is on the rise in the United States. Geothermal energy comes from heat below the Earth's surface. It has traditionally been used for cooking and heating, but now it has an expanding number of multiple applications, including swimming pool heating.
  • Hydrothermal power, a form of geothermal energy, is driven by steam and hot water, which is commonly used throughout America's west coast, Alaska, and Hawaii. Geothermal usage is expected to quadruple in the U.S. to 65.6 billion kWh by 2050.
  • Hydropower - Energy from waterways also goes back centuries, although its modern American usage peaked in 1997 at 356 TWh per year. By 2019 hydropower had declined to 290 TWh per year. On a global scale, hydropower is overwhelmingly the top source of renewable energy, as its leading producers include China, Brazil, Canada, the United States, and Russia.


Conclusion

The increasing use of renewable technologies is helping electric utilities achieve exponentially more efficient operations. All levels of government down to municipalities have begun to embrace renewable energy as a step toward sustainability. Legislation across the nation is leading to more eco-friendly policies as greener energy becomes an increasingly more viable financial and environmental solution.

Over 100 cities around the world are now powered by 70% renewable energy. The road is steadily being paved to further transition away from fossil fuels and towards solar, wind and other renewables to someday provide 100% of a city's electric power.
