Klugit Energy aims to deliver simple, quick and cheap demand-repose solutions to utilities and families with immediate benefits. Klugit is a smart plug that can be connected to any electric water tank, converting it into a smart one, Wi-Fi connected and smart-grid ready. Electric water heaters/tanks (EWS) waste a lot of energy in standby thermal losses (438 kWh/y for an 80L). Only in Europe there are around 28 mio EWS installed, equivalent to 12 TWh/y of wasted energy (same emissions as 2 mio cars per year). By installing Klugit and placing our sensor in external contact with hot water pipe, we use AI to learn your hot water usage routine and heat up water when you will actually need it, delivering immediate savings to families (>45 EUR/y). More importantly klugit is the cheapest and quickest way to provide “peak shaving” services for utilities, since it converts electric tanks into smart grid energy storage devices, solving one of renewable energy biggest problems.
