In this post we’re going to breakdown and explain what a charge code is and how it relates in particular to the street lighting industry. Charge codes can apply to illuminated signs and traffic signals plus many other pieces of equipment.
Before we continue, if you require a charge code for a piece of equipment you produce - we can manage the process and application for you, just get in touch or you can check out this infographic detailing the process.
What is an UMSUG Code?
UMSUG stands for Unmetered Supply User Group; the correct terminology is charge code and not UMSUG code. A charge code is a 13 digit reference that is assigned to a lantern; you will also be assigned a charge code for the control type, i.e. photocell.
This code enables the UMSO (Unmetered Supplies Operator) and MA (Meter Administrator) to calculate the electricity used for a particular piece of equipment. In the case of a street light, this will be the energy consumed by the lantern and the control equipment (photocell, Telecell, Node etc.).
These codes are required because street lights that are supplied by the DNO (Distribution Network Operator) are usually not metered and therefore the usage has to be calculated.
