VisNet, part of EA Technology, has reached a major deployment milestone with more than 25,000 VisNet Hub devices now installed across the UK’s electricity network. The achievement marks a significant step in supporting the resilience and modernisation of the national grid.
Installed at low-voltage substations, the compact VisNet Hub provides Distribution Network Operators (DNOs) with real-time grid-edge intelligence and actionable insights into network performance. With over 25,000 units live in the field, the technology now supports electricity supply to more than 5.5 million homes — around one-fifth of households across the UK.
As grid pressures increase due to electrification, renewables and rising demand, VisNet’s expanding monitoring network is playing a key role in helping DNOs better understand, manage and future-proof their low-voltage electricity networks.
Data collected by the Hubs provides real-time visibility into load behaviour, voltage levels, power outages, pre-fault identification, and reverse power flows across low voltage (LV) networks. It enables accurate insights into network utilisation, early detection of threshold breaches, and proactive management of both faults and distributed energy resources (DERs). These capabilities support more informed planning, reduce the risk of asset overloads, and can defer costly infrastructure investments. All of which is fed directly into Detect Pro, VisNet’s revolutionary user interface.
DNOs can then visualise and interrogate grid data through intuitive Detect Pro dashboards or receive the data on their own internal systems, allowing them to make well-informed operational decisions, detect future capacity challenges and plan investments more effectively.
There are over 800,000km of LV distribution networks in the UK – enough to circumnavigate the globe 20 times – all of which transfer power from transformers directly to homes and businesses. This network is coming under increasing strain given the rapid adoption of low-carbon technologies such as heat pumps, solar panels and EVs.
LV monitoring plays a critical role in maintaining these networks as they adapt to widespread electrification and the decarbonising world.
Mark McManus, Head of Monitoring at VisNet, said: “Reaching 25,000 units isn’t just a sales figure, it’s the moment the VisNet Hub goes from being a successful innovation to a national-scale solution.
“The milestone gives us scale, credibility, and real-world experience across the UK’s distribution network, and allows us to evolve our service in direct response to customer needs.
“Our technology is now providing actionable insights to help DNOs nationwide better plan, respond, and invest – all without requiring massive capital expenditure.
“They’re all crucial factors in the face of growing grid strain, and the Hub gives DNOs insight into their own network.
“Grid-edge intelligence is all about helping DNOs deliver better services to their customers and supporting national decarbonisation goals – and that’s what VisNet is proud to be doing.”
The Hub has also achieved more than 60,000 over-the-air updates across its fleet to date and was recognised in 2024 with a King’s Award for Enterprise in Innovation.
