To display instantaneous electricity demand and consumption.
This devices consist of three elements. Induction clamps clip around the power cable in your meter cupboard (three clamps for three phase). The clamps plug into a battery powered transmitter unit. The display unit receives wireless signals from the transmitter and displays instantaneous demand and records electricity consumption. Depending on the model, the consumption can be recorded at different intervals.

How it has been used to date
These have been used in schools that do not have automatic meter reading so that consumption can be recorded to prioritise action in behaviour change campaigns. Staff who regularly work from home have also used the monitors to help manage their energy consumption.
A range of products is available in this category at various price points. The higher specification models allow half hourly data collection, but all provide real time electricity demand display. They allow users to view historic data through associated software. “Wattson” enables the addition of a generation input, which will monitor the amount of power being generated by, for example, solar PV panels or a wind turbine, and allows users to see when they have “free” energy.
Collecting the data is not always straight forward for non-experts.
Users have to engage with the data, analyse the consumption and understand what actions they can take to in order to reduce consumption.

Some energy companies will provide these free of charge to their customers. Why not contact your energy company to find out? Otherwise the wireless energy monitors are available from £30 – £140.
