Sub-meter leads to refund of £65 000

Preparations by Marshall-Tufflex to install a voltage-optimisation system for a manufacturer of heating products identified that electricity meters were making incorrect readings, leading to a refund of £65 000 and an assurance that future bills would be correct. The e-tracker sub-metering unit took only about half an hour to install between the main supply cable and the main distribution board, and its readings were checked a week later.

Kristie Donachie, business-development manager with MT, explains, ‘The on-site mains voltage was very high — between 245 and 250 V — making it potentially a good fit for voltage optimisation. To enable a better fit for a VO unit and better payback, I suggested installing an e-Tracker for a week to get a better idea of energy usage. When fitting the e-Trackers, the electrical engineer noted that it was showing a different reading to the site meters. The client also mentioned that they had had questions about their usage for some time.’
