Value of grid friendly flexibility from smart water heaters

Abstract

This report examines experiences gained from BattFlex, which is one of four pilot projects in the large-scale demonstration project, “Intelligent Distribution of Electricity” (IDE). The IDE project is partly funded by Enova from 2019 to 2024, and managed by a consortium led by the Norwegian Smartgrid Centre. The consortium consists of grid companies Elvia, BKK, Tensio, Norgesnett, Lede and Glitre Nett, as well as NTNU and EPOS Consulting. The report describes the effects and benefits of grid batteries in low-voltage grids, customers’ smart water heaters, and bilateral agreements with end customers. The pilot project demonstrates the importance of good collaboration between grid companies and suppliers. In BattFlex, collaboration has led to innovation and product development that can reduce voltage quality issues in weak or exposed low-voltage networks, which is more cost-effective than conventional grid reinforcement measures.
