PECU Logger

Unmetered electricity is used by street lights, traffic lights and other similar electrical equipment. In total, unmetered energy accounts for about 1.25% of the UK’s total electricity consumption. The largest volume of unmetered energy is consumed by street lights.

Recent changes to the Carbon Reduction Commitment (CRC) regulations mean that local authorities can save in the region of 1% of their street lighting energy cost by investing in a PECU Logger to calculate their unmetered energy consumption based on ‘Dynamic Half Hourly data’.

Dynamic Half Hourly is the most accurate trading method available for unmetered supplies. It uses the data available from a PECU Array to accurately calculate kWh consumption each day. It is referred to as ‘Dynamic’ because it is set up to dynamically record the actual switch on / off times of lighting units within the Customers inventory; Meter Administrators use this information for the energy usage calculations.

PECU Logger Mk4 (Patent Applied For)

EGS is the UK’s leading provider of PECU Loggers to street lighting authorities and is pleased to introduce the latest in PECU pecu logger 1Logger technology, the PECU Logger Mk4. Building on our experience and the success of the Mk1,2 and Mk3 PECU Loggers, we have made use of the latest micro computer technologies whilst crucially retaining compatibility with legacy metering software and offering future proofing capabilities to protect your investment.

The Mk4 integrates a GSM modem for wireless connectivity, whilst still providing support for any customers with a legacy wired telephone connection. This simplifies and reduces the cost of installation by not requiring a landline connection to the roof.

The new Mk4 also introduces a more accurate clock than previous systems utilising ‘Cellular Network Time’ as a clock reference. There is also the option to implement a M2M connection or if there is a requirement in the future to utilise a ‘Cloud’ based data transfer model.

Following revisions to the ELEXON BSCP520 document, we have been able to make the light meter optional thereby reducing the initial cost of the system and also removing the cost of on-going calibration.
