ENERGY DATA MANAGEMENT: The solution for greener production?


Industrial manufacturers are among the world’s


biggest energy consumers, contributing more than 30% of total greenhouse


gas emissions. Here, Garry Forfar of COPA-DATA UK, explains how energy data management systems (EDMS) can help to


lower consumption and achieve net-zero


E


nergy management initiatives have seen a resurgence in recent years, driven by a


need to reduce costs and boost reputation. In the last few years, we have seen a wave of manufacturers improving their green credentials, investing in carbon capture and storage (CSS) technologies, and offsetting their emissions. For example, BrewDog used this method to launch itself as the world’s first carbon negative brewery. In September, the British Government


also announced a £220 million investment to its most polluting industries to cut their carbon emissions. The grants of up to £30 million will allow companies to invest in more efficient boilers and electric motors, as well as developing technologies in the renewables space. While these efforts are noble – and


in some existing cases, are incredibly successful – it is vital that manufacturers first understand the exact composition of their energy usage.


EDMS BENEFITS Most manufacturers believe they already have an EDMS in place. They know how much energy is required to run their plant and might consider ways for them to reduce their bills. Often, this is limited to shutting off lighting and using smart meters to monitor HVAC systems. Energy management can, however, be smarter. An EDMS should use Internet of Things


(IoT) technologies and devices to gather consumption data from the entire facility. It should analyse different equipment and processes, and present this data to operators – enabling them to make decisions. For industrial applications, the system should look beyond purely

electricity use, and include the volume of air, gas and water used in each process. Take a soft drinks manufacturer as an


example. Let’s say the facility has two identical air compressors used for pushing different flavourings through pipes and into vats holding the product. The processes are identical, and therefore their energy usage should be too. While reducing a small percentage of air wastage may seem trivial, these small changes can reap significant gains. An EDMS can make this fast and


straightforward. It should automatically analyse the amount used by each compressor. If the output is more or less, an operator can investigate and make operational changes to avoid wastages.


IDENTIFYING SAVINGS Even small savings can go a long way in manufacturing, especially as external costs continue to fluctuate. Industry leaders have already warned that the ongoing fuel crisis could halt production for some UK factories. Furthermore, many corporate customers of these manufacturers are refusing to pay more for products or take on this knock-on effect. For manufacturers with large contracts


with supermarkets, retail chains and restaurants, reducing costs in other areas is the only way to stay afloat. An EDMS can help by highlighting areas


for improvement that would not be possible to spot without an overview of the entire facility. Legacy equipment, for instance, can often fall behind in efficiency compared to


newer models. When using an independent EDMS, such as COPA-DATA’s zenon, users can monitor data from new and existing machinery, regardless of their brand or communication protocol. This feature allows an EDMS to collect


energy usage statistics from the entire plant. When visualised on a dashboard, an operator can then use this insight to make changes where necessary. This could be as simple as performing


maintenance on our aforementioned air compressor, or installing automation to reduce high levels of energy usage in

legacy equipment. Examples of this could include deploying a soft starter, variable speed drive (VSD) or investing in an energy efficient electric motor. Most manufacturers are actively looking


for ways to reduce their emissions, but to achieve greater efficiency – or ambitious net zero targets – they must first gain an overview of their current consumption across the facility. Energy reduction via an EDMS is therefore key to achieving greener production.
