Net Metering questions

A+ A-
As instituted with Ministerial Decision ΑΠΕΗΛ/Α/Φ1/οικ.24461 (Government Gazette B/3583/2014), and in accordance with MD ΥΠΕΝ/ΔΑΠΕΕΚ/15084/382, (GovGaz B/759/2019), the development of photovoltaic systems by self-generators (“prosumers”) involves the installation of fixed photovoltaic systems to meet consumers’ own need for electricity and the application of an energy offset.

Energy offset, or net metering, means that the energy generated by a photovoltaic system is offset against the energy consumed at the premises of the self-generator, and it is calculated on a three-year basis. In net metering, it is not necessary for the energy generated to coincide with the energy consumed.
Those entitled to install such a system are natural persons and legal persons governed by public or private law who either own the space where the system is to be installed, or they have lawful access to it (e.g. through a lease) and have obtained written consent from the owner of the site.
Where the generation system is in a common-use or jointly owned part of a building, one or more systems may be installed, each of which corresponds to just one meter. Those entitled to install a net metering system in this case are the owners of the horizontal properties (flats) or those who have lawful use of them, once they have been granted use of the common-use or jointly owned space or section of the space by the other co-owners.
  1. There must an active and permanent power supply in the name of the self-generator which supplies the electrical installation.
  2. The photovoltaic system must correspond to one electricity meter, which is the meter for the installation it supplies.
  3. The system must be installed at the same or an adjacent site to the electrical installation that it corresponds to.
  4. The applicant must have lawful use of the site where the system is to be installed.
  5. The applicant must have paid all electricity bills issued by the relevant suppliers or have made arrangements to settle any outstanding debts.
  6. The self-generator’s supply must not be a beneficiary of the Environmental Residential Tariff (MD ΥΠΕΝ/ΥΠΡΓ/26359/4101 – GovGaz B/1936/30.5.2018).

The net metering agreement signed between the provider and the self-generator is for a 25-year term, starting from the date the connection with the photovoltaic system is activated.

In the event of a change in provider after the system’s activation, the net metering agreement with the previous provider is automatically terminated and a new net metering agreement is concluded between the self-generator and the new provider for the balance of the 25-year period.

Similarly, if the contracting customer of the electrical installation changes, a new net metering agreement is concluded for the remaining time period. 

Metering of electricity generated by the energy system and the incoming and outgoing energy from and to the grid is undertaken at the same time by the Hellenic Electricity Distribution Network Operator (DEDDIE), during the current metering cycle which applies to the self-generator’s electrical installation.

The provider applies net metering on the “actual” electricity bills, based on the consumption measured by DEDDIE, according to the metering cycle in effect. In the event that it is not possible to obtain a meter reading on the scheduled metering date, net metering will be applied when the next regular metering takes place.

Regulated charges are calculated as follows:

  1. The special duty for greenhouse gas emissions reduction (ETMEAR) is calculated based on the absorbed energy and the corresponding unit charge.
  2. The variable part of the infrastructure use charges and network use charges (energy charges) is calculated based on the absorbed energy and the corresponding unit charge.
Charges for Services of General Interest are calculated based on the total energy consumption and the corresponding unit charge. If tariffs from different time zones are involved, the total produced and guaranteed energy will be used to calculate the charges for general interest services corresponding only to the normal charge zone (day use charges).
