The UK government has made a pledge that by 2020 every domestic user of gas and electricity will be offered smart meters at their point of supply. These meters will offer real time consumption information, so users will be better informed on how much energy they are using and how much it is costing. Armed with this information, it is hoped that consumers will become more energy usage and cost conscious and make choices that reduce both.In our experience, the largest users of energy know very little about how much energy they are using at any given load centre or distributed point of usage. All consumers have tariff metering at the point of supply for billing purposes but most are unaware of how much energy they are using for a specific task or process.The first challenge on the path toward reducing energy consumption is to find out exactly how much is being used, where and when. Metering on electrical distribution equipment and apparatus has, in the past, been a minor consideration and as this type of infrastructure is not routinely upgraded, we are left to rely of inaccurate and uncalibrated analogue meters to determine usage. Modern metering can offer instantaneous and historical power consumption information through to power factor and individual harmonic analysis. Systems can start as single standalone metering points and be expanded to becoming network connected schemes interfacing to your SCADA or DCS control systems, displaying consumption in real time. Terrella have experience of surveying installations, preparing distribution drawings, identifying metering points and installing energy metering on electrical switchgear and networks.
