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.
