An energy management system (EMS) is a system of computer-aided tools used by operators of electric utility grids to monitor, control, and optimize the performance of the generation or transmission system. Also, it can be used in small scale systems like microgrids.[1][2]

Terminology

[

The computer technology is also referred to as SCADA/EMS or EMS/SCADA. In these respects, the terminology EMS then excludes the monitoring and control functions, but more specifically refers to the collective suite of power network applications and to the generation control and scheduling applications.

Manufacturers of EMS also commonly supply a corresponding dispatcher training simulator (DTS). This related technology makes use of components of SCADA and EMS as a training tool for control center operators.

Operating systems

Up to the early 1990s it was common to find EMS systems being delivered based on proprietary hardware and operating systems. Back then EMS suppliers such as Harris Controls (now GE), Hitachi, Cebyc, Control Data Corporation, Siemens and Toshiba manufactured their own proprietary hardware. EMS suppliers that did not manufacture their own hardware often relied on products developed by Digital Equipment, Gould Electronics and MODCOMP. The VAX 11/780 from Digital Equipment was a popular choice amongst some EMS suppliers. EMS systems now rely on a model based approach. Traditional planning models and EMS models were always independently maintained and seldom in synchronism with each other. Using EMS software allows planners and operators to share a common model reducing the mismatch between the two and cutting model maintenance by half. Having a common user interface also allows for easier transition of information from planning to operations.

As proprietary systems became uneconomical, EMS suppliers began to deliver solutions based on industry standard hardware platforms such as those from Digital Equipment (later Compaq, then HP), IBM and Sun. The common operating system then was either DEC OpenVMS or Unix. By 2004, various EMS suppliers including Alstom, ABB and OSI had begun to offer Windows based solutions. By 2006 customers had a choice of UNIX, Linux or Windows-based systems. Some suppliers including ETAP, NARI, PSI-CNI and Siemens continue to offer UNIX-based solutions. It is now common for suppliers to integrate UNIX-based solutions on either the Sun Solaris or IBM platform. Newer EMS systems based on blade servers occupy a fraction of the space previously required. For instance, a blade rack of 20 servers occupy much the same space as that previously occupied by a single MicroVAX server.

Artificial intelligence-based EMS are today's digital tools in energy saving

The first step towards a more efficient energy system is to understand how much energy we consume and where it comes from. This requires an overview of all the activities that take place in our homes or offices.

The second step is to identify which of these activities can be automated so as to save energy. As a result, the industry is relying on the power of Energy Management Software (EMS).

Throughout the literature on the subject, the acronym EMS is often used interchangeably to describe both Energy Management Systems and Energy Management Software. For this article, we will use it to talk about Energy Management Software.

What is Energy Management Software?

Energy management software is a digital tool that allows you to monitor energy consumption and manage it by automating certain tasks. In addition, EMS also provides insights on how to improve efficiency and cut costs further. Informed decisions help you make better choices regarding the levels of your energy usage.

The main goal of these systems is to reduce costs by optimising consumption and production processes. But you're probably wondering how this works, aren't you? So, let's not waste more time!

How does Energy Management Software work?

Energy consumption data can be analysed using computer programs such as those based on artificial intelligence. These programs help us to find out which activities are consuming too much energy and which ones can be improved by changing their behaviour.

This is done by a framework encompassing three phases: reporting, monitoring and engagement.

Reporting

First, the user must report his/her energy consumption. The information collected will then be sent to the EMS.

Monitoring

Next, the EMS analyses the data received and identifies the most relevant actions to automate. For example, if there is no need to heat the environment during winter, the EMS platform might turn off heating devices automatically when temperatures drop below a certain threshold.

Engagement

Finally, the EMS sends recommendations to the users about how they can optimise their energy usage. It may suggest that they install new appliances or change their habits. The cloud-based nature of the software makes it possible to share these suggestions with other users.

It’s also essential to note the importance of incorporating both state-of-art hardware (power meters, HVAC controllers) with the right software platform (energy manager) to deploy a well-designed Energy Management System for your business.

What are the benefits of an Energy Management System?

There are many reasons you should consider investing in a proper Energy Management System; the right software can also be a game changer for handling your energy usage efficiency. Here are some benefits to consider:

  • Reduce carbon emissions

One example is the reduction of CO2 emissions through the optimisation of lighting. If you have several lights installed throughout your office, you can set them to switch on only when needed. This way, you'll avoid wasting electricity, thus reducing your carbon footprint.

  • Improve comfort levels

To improve comfort levels, you can use smart thermostats to adjust temperature settings depending on the season. You can also save money by turning off air conditioning units when rooms are empty.

With competitive price and timely delivery, acrel sincerely hope to be your supplier and partner.

  • Increase productivity

An Energy Management Software can help with the productivity of employees. By setting up automatic alerts, you can notify staff members when their equipment needs maintenance. This way, you won't have to worry about forgetting to schedule repairs.

  • Optimise energy use

We have talked a lot about the optimisation provided by Energy Management Software, but to be more concise, let's make it clear that these systems give you real-time insight into everything related to managing electricity. They are, therefore, a vital component of any production line: they improve quality, increase productivity, and simplify operations.

  • Improve security

Energy Data Management Systems allow you to monitor and control access to critical areas such as offices, warehouses, factories, etc. They can even be connected to alarm systems to ensure safety and security.

  • Ensure compliance with regulations

EMS can ensure that you meet the requirements of various regulatory bodies. In addition, they can help you comply with local laws regarding energy consumption. For example, the laws governing the installation of solar panels require you to keep records of the amount of power generated by each panel. An Energy Management Software will help you do this efficiently.

An automated solution for managing electricity usage at any scale will enable companies to implement sustainable business practices. This will help your organisation to get "green" certifications and get closer towards fulfilling its ESG policies.

What is the purpose of ISO 50001?

The ISO 50001 certification is a standard designed to promote energy management in organisations. It defines best practice guidelines for measuring, reducing and reporting energy use.

It was developed by the International Organisation for Standardisation (ISO), a non-governmental international body that develops standards for products and services around the world.

The aim of ISO 50001 is to encourage businesses to adopt energy management solutions. In other words, it aims to make sure that all companies have access to tools that allow them to measure, reduce and report their energy use. Not to mention, the certification can help to cement the companies reputation as a credible operation. 

So, to get such recognition, you must choose carefully which energy management software will play an important role in saving energy in your business.

Energy Management Software Companies to look out for

Sustainably reducing energy costs has become a core business endeavour of a lot of startups, and there are several notable companies trying to solve this problem by offering different kinds of products and services.

Here we list seven companies that are providing potential products that could positively affect the energy management systems industry.

Hello Energy, for example, offers a cloud-based energy management software that helps property managers save money while improving their comfort level, and lowering carbon emissions. In 2020, the startup raised USD$ 1 million from a deal led by Enfuro Ventures. 

Parity is another company in the venture capitalists’ spotlight, having raised USD$8 million in a series B funding in 2022. The company uses machine learning algorithms to predict future energy needs and then optimises energy usage based on these predictions.

Energy management software startups like Hello Energy and Parity are helping to improve the efficiency of our homes and buildings. They are also making it easier for us to monitor and control our energy consumption.

Why is energy management necessary?

There are several reasons why energy management is so important. We've outlined in this article the benefits of having a structured energy management system, including the costs saved, increased efficiency and sustainability goals achieved. And when everything is powered by a trusted and robust software, things become much easier.

But, know this, the necessity of energy management is not only about saving money but also about protecting the environment. By using less energy, we are able to reduce our carbon footprint and help the planet.

In addition to that, energy management is essential because it allows us to track how much energy we consume and where it comes from. This way, we can find ways to cut down on greenhouse gas emissions.

Challenges to implementing an Energy Management System

Uncertainty is an inevitable part of any smart grid. There may be unexpected delays due to unpredictable human behaviour, erratic Plug-in Electric Vehicles (PEVs) driving patterns, weather conditions and intermittency in sources.

Also, ensuring the security and privacy of customer data needs to be a crucial part of your energy management strategy.

However, one of the biggest challenges with implementing a whole system powered by hardware and software for energy efficiency is the time required to set up and deploy it. The results may not be immediate.

That is why you will want a skilled workforce to help you keep up with the latest trends in technology. But not only do you need to look for the best, but also for the most precise. That is because every Energy Management Software has its nuances, and they can work as a centralised, a decentralised and a hierarchical system.

Centralised approach

A centralised Energy Management System is a single point of contact for all customers. It gathers information from multiple devices and sensors, and provides a unified interface for managing energy usage.

This type of system is usually implemented through a cloud-based platform. In other words, it’s a web application that runs on servers located somewhere else beyond the physical location of the device.

This means that the server is always connected to the Internet, making it possible to access it from anywhere.

Centralised systems are very useful if you have a large number of users who share the same account.

For example, if you run a hotel chain, you could use a centralised system to manage the energy usage of each room. You would then be able to see how many guests are staying at each room, and whether there are any unusual spikes in energy consumption.

You could even send alerts to the front desk if someone starts using more electricity than usual.

Decentralised approach

A decentralised Energy Management System is a distributed network of devices that communicates directly with each other. Each device acts like a node in the network having autonomous control capability, and communicating with other nodes via wireless communication protocols such as Zigbee, Wi-Fi, Bluetooth, etc.

In this case, the user doesn’t necessarily need to log into a central website to view their energy usage. Instead, they can simply connect their smartphone or tablet to the network and receive real-time updates about their energy usage.

This kind of Energy Management System works well when you have a small number of users who don't share the same account. For example, if you own a home where you live alone, you might install a decentralised EMS so that you can monitor your energy usage without having to log into a central site.

Hierarchical approach

The hierarchical approach is similar to the decentralised approach, but it adds an extra layer of security. This allows you to create different levels of access depending on the authority you give certain users.

For example, you could allow managers to view data about individual employees, while allowing supervisors to view data about entire departments. This way, you can ensure that sensitive information is protected.

Choosing the best approach to manage your energy

Every Energy Management System approach has its benefits and purpose for a specific business. But, we can use some enlightenment from the industry to help guide our thinking when working with the hypothetical pros and cons of each model.

We can summarise these points by saying that centralised systems has global optimisations and therefore lower costs than decentralised systems. However, decentralised systems has lower computational burdens and lower response times than centralised systems. 

The decentralised systems have better reliability, but they are not well-suited for macrogrids. And when selecting a hierarchical approach, you must be aware that the complexity of implementation of this type of system is high.

All these systems being put forward require you to get skilled people onto the team. However, there aren't enough skilled people available as we face a serious tech talent scarcity in today's market. To counter this problem, you need to consider partnering up with experienced professionals.
