This document provides customers with information on ESB's tree and vegetation trimming programme.

To date, ESB Networks have not required visibility/sensors on the low voltage (LV) network as the design standards and consumer loads have not greatly varied over the last few decades.  In the coming years, as more and more customers adopt low carbon technology (LCT), the loading on the LV network will increase dramatically and will challenge the design limits.

It is expected that in time, with full Smart Meter rollout, development of appropriate IT (compliant with all GDPR requirements) could allow for a ‘bottom up’ assessment of transformer loadings. However, in the interim period, it is important to obtain vision of the capacity of the LV network, in particular the capacity of transformers, so that any reinforcement which might be required can be programmed in advance of overloads taking place.

In advance of obtaining smart meter data, an interim solution which provides vision of the capacity of transformers needs to be low-cost, and easy to install safely with minimum interruption of supply to customers, to ensure that the cost-benefit is maximised. This meant that installation of traditional load monitoring devices could not be entertained. To this end, the project sought to assess the viability of LPWAN (Low Power Wide Area Network) IoT Temperature sensors to provide an indication of transformer overload. It was expected that temperature sensors would provide early warning of loading levels and hence allow the pre-emptive uprating of the Substation capacity. It was decided to build upon a previous innovation project which used the Sigfox network to develop a proof of concept for low-cost harvesting of data.
