We would like to inform you that HEDNO, as the Non-Interconnected Islands (NII) operator, published on 23.06.2025 the Notes on Billing of the RES Producers who are operating at NIIs for the May 2025 billing period.

Please note that for the current May 2025 billing period, a Corrective Billing was implemented for the excess annual production energy under Article 48 of Law 4951/2022 on the “Upgrading of PV Station Energy Equipment” for audit year 2023, due to the recalculation of the maximum annual energy production of the first five years of operation of PV Stations. Therefore, the credit notes for Producers whose PV Stations showed excessive energy production during the 2022 audit year were recalculated.

The Information Notes can be accessed online via the RES & CHP Online Clearance Notes System.  The app is available here https://apps.deddie.gr/ApeInvoicesInfo/intro.html or by visiting the “Enter the RES Producers App” link located in the Non-Interconnected Islands section of HEDNO’s website.
