HT/NT stands for Hochtarif and Niedertarif. These meters have two counters which measure the consumption for two different time zones (during the day and during night).
​
If your meter is used for household electricity, you can easily sign up for the SimplyFair rate on our website. The grid operator will inform us whether there is a heat pump or storage heater at your home, and we will automatically adjust your tariff accordingly. Please note that we do not differentiate between HT and NT; we always charge the same unit price.
