The D1 tariff calculation tool has been discontinued.
Starting from 2017, no electricity tariffs are in effect:
D3 for non-residents and residents with more than 3 kW
D2 for residents up to 3 kW,
D1 experimental tariff for heat pumps
A new tariff has been introduced (called TD) variable only on the basis of the power used and the kWh taken from the grid by the individual customer.
