A uniquely accurate and informative service that we also offer is Energy Monitoring and Management. Our aim here is to give clients a thorough understanding of the energy supplied to their buildings, how it is used and billing/metering accuracy. We have found a significant majority of our customers to be unaware of these opportunities, that could be potentially be rectified to make significant savings. We produce energy consumption reports on demand with active alerts and use our ETCS Energy Dashboard to demystify the results and clearly show ways that the savings can be made.
Load assessments are a key area where savings can be made, by identifying where companies are charged for superfluous KVA capacity that they will never use. Companies are charged according to the KVA capacity they are given, and it is difficult for them to discern whether this is an accurate representation of their needs. We can provide detailed analysis of the electrical intakes to show how much you use on average, the highest peak values recorded and therefore recommend a sensible limit. There are however, things to consider such as future change of use or significant increases in electrical load which need to be accounted for. Equally you may be in excess of your KVA allowance and are charged accordingly by your provider.
An area that is always of particular interest to customers is validation of electricity bills. We are able to use our monitoring process to determine the accuracy of electricity meters, either to give our clients peace of mind or to be used as evidence in a dispute against electricity providers. If a meter is found to be faulty, the customer is able to claim compensation as far back as 7 years which can be a significant payout.
Voltage stability is the measure of how much an electrical supply fluctuates over time. This is an output that we can show graphically as part of energy monitoring. This information gives us a clear view of what voltages the system is being subjected to, and how voltage optimisation could potentially improve the system. Electrical equipment has an optimum voltage to work at which is usually around 225volts. Exposing this equipment to a voltage above this maximum not only uses more electricity but also drastically reduces its working life. Voltage optimisation uses a transformer to reduce the working voltage to an optimum level so that this equipment lasts longer and uses less electricity. The viability and payback period of installing voltage optimisation equipment is also critically evaluated as part of our energy reports.
In an electrical circuit there is a difference between the perceived power available (apparent power) and the actual power available to do work (real power). The proportional difference between these two figures is the power factor. By examining the power factor we are able to determine how much power is being lost in the system as “reactive power”. These values then enable us to investigate the viability and payback period of installing power factor correction equipment which works to optimise the power factor.
Energy monitoring gives a unique insight into where and when energy is being consumed across a company’s site. This is shown graphically over time to give a clear view of the consumption of the system. This is especially useful for identifying electrical waste out-of-hours or in unused parts of the building. Situations such as fans being left on overnight and under floor heating being left on in abandoned buildings are just a couple of examples of major energy-waste identified from this process. As well as this it can also be used to document the energy requirement of a site. This is especially useful when looking to install new energy saving products.
