GSE – New methods of calculating the advance instalment of JANUARY 2018 applied from October. DISCOVER how they work.


Since October 2017, GSE has made operational the new "Methods for updating the advance instalment due for the incentive on the feed-in tariff of photovoltaic solar plants”. The main introduced innovations are

  • The advance instalment is re-determined every 3 months instead of every 12 months.
  • The new algorithm is based on the monthly energy readings communicated by the Distributor Grid and actually present at the GSE Portal, potentially arriving to zero the distributed advance instalment.

Considering the new methods of calculation, it is recommended that the persons in charge periodically monitor the presence of readings communicated by the Distributor Grid to GSE, to avoid any partial or total absence of readings. Please refer to paragraph 3 of the GSE Document for details on the methods of calculation
