New Electricity Tariff TD

There is to be a change to electricity costs starting on 1st Jan 2018.
I have put the information from our company site, so in Italian, but google does a reasonable translation.

Most of the new tarrif changes came in at the beginning of this year - reducing considerably the saving/advantage of the D1 tarrif. From the info it seems that those on the existing D1 tarrif will continue but in reality there will not be much, if any, saving over the TD tarrif
