Voltage Regulation

Voltage regulation, also known as voltage optimisation, is a voltage management technology that reduces energy consumption and electricity costs. Installed behind the meter on a site, voltage regulation conditions incoming grid power to match the voltage required by equipment on-site.

Typically, UK mains electricity is supplied at 230V, with a tolerance of +10% and –6%. This means that in practice, UK sites can be supplied with voltages ranging between 216V and 253V. Sites that are being supplied with overvoltage or undervoltage will see the most benefit from voltage regulation, but almost all sites will be able to secure savings via improved energy efficiency. Most infrastructure and equipment will operate more efficiently and with less need for maintenance at lower voltages.

Voltage regulation also smooths out the peaks and troughs that can occur in voltage supply from National Grid, making your site more resilient by supplying equipment with a steady, reliable voltage and avoiding sudden surges or sags in supplied power.

While voltage regulation offers both improved power resilience and potential energy savings, it is important to note that the benefits it offers vary significantly depending on site, and in particular depending on the current voltage you are being supplied with by the grid. This means that a site survey from a reputable supplier is a vital first step when considering voltage regulation technology.
