Half-hourly meters

What is a half-hourly (HH) AMR meter?

An Automated Meter Reading (AMR) electricity meter is a type of metering system which uses automatic meter reading technology to split your energy consumption into more accurate 30-minute blocks called half-hourly (HH) metering.

AMR meters rely on fixed communications, which send remote, automated meter readings to the energy supplier every half-hour. Using this data with monitoring and targeting software such as our SSE Clarity platform, allows you to identify ways you can reduce your energy usage and carbon footprint.

Why do I need one?

Larger businesses typically benefit from half-hourly meters due to their high energy consumption, which is very difficult to measure using a standard meter. Half-hourly customers are billed using 48 half-hourly data periods for each 24 hours. This level of detail reveals what is being used on a day-to-day basis, helping us to forecast much more accurately and helping our customers to get an accurate picture of their energy use, and see where they might improve/reduce their consumption.

For sites with an electricity capacity of 100kW or more, half-hourly meters are mandatory by law.
