Energy Efficiency

Whether you are trying to reduce your carbon footprint, spending on energy or vulnerability to power disruptions, the cheapest, easiest, and quickest thing to do is improve energy efficiency.

The overall energy efficiency of a site is difficult to measure, and it is not typically a core aim when installing, maintaining, or upgrading electrical equipment. However, it can be quick, easy, and highly profitable to look at improving your energy efficiency.

Simply upgrading transformers saves 7% energy use of some equipment. Installing voltage regulation to a site can reduce total consumption by a similar amount. Adding battery energy storage or a microgrid control system will achieve maximum energy efficiency by optimising where and when the energy is delivered.


Electricity costs continue to rise and pressures for businesses to reduce carbon emissions are growing. Simultaneously, the current energy transition is moving away from traditional fuel sources as everything becomes electrified. Your communications, critical processes, money, data, and even your car and heating are quickly becoming reliant on stable electricity.

Therefore, it is vital for your business to actively manage and optimise its energy profile to be as efficient as possible. Optimising your energy efficiency helps minimise CO2 emissions, reduce overheads, and bolsters power resilience.

This is particularly important if you use a high amount of electricity for your day-to-day business operations. However, almost all businesses will feel the impact of rising energy costs and would benefit from improved efficiency.


The first step is to understand your business’ energy consumption and identify where improvements can be made. Initial identification can be easily achieved in a non-invasive manner by analysing a site’s consumption and generation data.

Depending on what the analysis shows, businesses can optimise and enhance energy efficiency in a number of ways:

  • Regulating the incoming voltage supply to protect against voltage spikes and dips, protecting sensitive electrical equipment while reducing energy consumption and costs
  • Reducing reliance on the electricity grid with on-site generation, helping minimise inefficiencies inherent in the supply from the antiquated electrical grid, and reducing the non-commodity aspect of your energy bills
  • Utilising battery energy storage technology that allows for greater control and flexibility of your electricity use. This can help you reduce electricity costs and maximise output from on-site generation, fundamentally improving the way your electricity is generated and consumed
  • Improving high voltage (HV) infrastructure by replacing aging distribution transformers can protect your site from unplanned downtime through equipment failures. Additionally, modern transformers are generally much more efficient and subject to lower losses
  • Implementing a sophisticated microgrid control system with ongoing data collection and analytics provides the ability to identify opportunities for further energy efficiency measures to be deployed
