What is net metering?

By the term net metering, we mean the energy offsetting of generated-consumed energy through self-generation and self-consumption by RES. (photovoltaics and wind turbines). In a nutshell, the consumer is allowed to cover one or all of his or her own consumption, which practically means a substantial exemption from PPC bills for 25 years (25-years association agreement). Energy offsetting is the offsetting of the energy produced by the photovoltaic system with the energy consumed at the plants of the self-producer, which is carried out on an annual basis.

What is the maximum power and where can it be installed?

The maximum power of the photovoltaic system, in the interconnected system, is up to 20 kWp or 50% of the agreed power consumption (≤ 0,5 x agreed with HEDNO power supply in kVA), provided that the value is higher than the above limit of 20 kWp. Under no circumstances should the system exceed 500 kWp.

In non-interconnected islands, the limit is 10 kWp and in Crete 20 kWp, or 50% of the agreed power consumption (≤ 0.5 x agreed with HEDNO power supply in kVA), provided that the value is higher than the above limit. The highest limit is set at 50 kWp for Crete and 20 kWp for the other islands.

The installation can be carried out on a building or ground or other construction including those of the primary sector (agricultural - livestock farming areas).

Who can join the net metering program?

Individuals (traders or non-traders) or legal entities of public or private law who either own the space in which the photovoltaic system is installed or have legal use of it (e.g. through leasing, free concessions etc.) are eligible to join the program, having secured the written consent of the owner. It concerns homes, crafts, industries, drilling, livestock farms, agricultural units and any installation can be powered by electricity.

What happens in case of many properties or shared spaces?

In case of a shared or commonage building site, installation in one or more systems is permitted. Owners of horizontal properties or their legal users are entitled to join the Program after granting the use of the shared or commonage space or part of it by the other co-owners. The agreement of the co-owners is a prerequisite, as well as that each photovoltaic system is assigned exclusively with a consumption meter.

I am a tenant. Can I join the program?

Individuals (traders or non-traders) who have legal use of it (e.g. through leasing, free concessions, etc.) have the right to join the program, having secured the owner's written consent. So, the tenant can join the program.

But do I pay more for other bills than for electricity?

Through the net metering program, it is foreseen that self-producers will only be charged an SGP charge. (services of general interest) for all energy consumed and exempted from the ETMEAR (Special Gaseous Emission Reduction Fee) charge for the portion of energy they generate themselves. More specifically for current PPC invoices the offsetting will be for the home consumer at around 0.185 € / kWh and the commercial at 0.11-0.165 € / kWh (including VAT). The offsetting is about energy, so even if the price of kWh is increased, it will not be our concern, as we do not equate money but energy. Our investment becomes more profitable by the increasing of the price of kWh.

And what is the duration of the Program but also the predicted procedure before and after the program?

The period is set by the Energy Offsetting Contract between the self-producer and the electricity supplier (PPC and other electricity supply companies) and is 25 years, with the photovoltaic system connection date starting. In case of change of electricity supplier, a new contract is contracted for the remaining of 25 years.

The predicted procedure is:

Application - Connection Offer - Connection Contract - Energy Offsetting Contract Documentation from a relevant Engineer is also required upon application. The basic prerequisite for signing the contract is the full payment of the energy supplier's invoices and the existence of an active supply in the name of the producer.

The energy offsetting is annual, but the consumer is required to pay the bills on a monthly, 2-month or 4-month basis depending on the installation and the invoice. The final clearance is made at the annual offsetting. If we have produced less energy than we have consumed we pay the difference, and if we have produced more there is no compensation. In any case, after the annual clearance, nothing is transferred to the new year.

What will be the layout of my installation?

The photovoltaic system will have no difference in what we have known so far, the difference is in the metering system.

The existing electricity consumption meter is replaced by two bi-directional-recording meters. Meter 1 measures the energy produced and consumed by a photovoltaic system and Meter 2 measures the incoming and outgoing electricity to and from the network.

There is no room in my roof, what happens in this case?

It is possible photovoltaic systems to be installed in the same or adjacent space as the power plants. Photovoltaic systems can be installed on buildings or on the ground or on other structures, including those in the primary sector, in accordance with the existing urban planning legislation.
