The Tone Frequency signal is ending
If you buy electricity at normal and off-peak rates and do not have a smart meter, or if you have an electric boiler, then you make use of the Tone Frequency (TF) signal. This signal tells your meter and/or boiler when daytime and night-time consumption starts. On 1 July 2021, the grid operators (including Stedin, Liander, Enexis and Enduris) will be cutting off the TF signal. More information on precisely what that means for you is presented on this page.
