IN Brief:
- Kight’s planned Dumfries facility would bring domestic battery assembly into Scotland, linking manufacturing scale with early social-housing deployments.
- The 10kWh PowerHub combines a non-graphite anode battery design with a 4G-connected EnergiFlow control platform that shifts charging around tariff and grid signals.
- The bigger electronics play is a managed residential storage architecture in which battery chemistry, control software, communications, and power management are designed as one system.
Kight PowerHub is moving its residential storage programme into manufacturing, with plans for a new Dumfries facility to assemble its 10kWh home battery systems at scale. The project ties a new production base to a product that has already been trialled in social housing across the south of Scotland, where the company has been positioning the unit as a route to lower bills, stronger backup resilience, and easier participation in flexible electricity tariffs.
The electronics story sits as much in the control layer as in the battery pack itself. Kight’s PowerHub is built around what it describes as a non-graphite anode chemistry, with no cobalt or graphite, alongside a 4G-connected management stack and a 25-year warranty target. The published specification also points to full depth-of-discharge operation, operation from -30°C to +55°C, and a lifecycle of up to 20,000 cycles. Those figures place the product in a part of the domestic storage market where long-life control electronics, communications, and software support matter just as much as the cells.
At the centre of that proposition is EnergiFlow, Kight’s AI control platform. The software learns household usage patterns, reads smart meter and pricing signals, and decides when to charge, hold, or discharge energy to minimise spend while working alongside solar and other on-site generation. That turns the battery from a passive backup box into an actively managed electronic asset, one that is expected to respond to tariffs and household demand rather than simply store whatever energy happens to arrive.
The pilot work gives the product a stronger footing than a factory announcement alone would provide. South of Scotland Enterprise said in 2025 that the first 11 units were being deployed across registered social landlord properties in the region, with the system designed to reduce bill pressure for homes facing high electricity costs. Kight’s own case studies put projected savings in the 64% to 79% range over the first six months in early installations, with gains expected to rise when solar output improves. “Seeing the difference the PowerHub makes in people’s everyday lives is exactly why we built this company,” said founder Lawrence Fagg.
That matters because the domestic battery market is beginning to split into two camps. One is still selling storage as a sealed hardware box. The other is selling a managed electronics platform that combines chemistry, control software, connectivity, insurance positioning, and long-term service data. Kight’s Dumfries move is a bet that the second model will have more room to grow.
