In a few words..

Net Metering allows the consumers to cover an important part of their consumption whereas  it gives them the ability to use the grid for indirect storage of green energy.

The term “Net” comes from the fact that the debit/credit of the consumer is about the difference between produced and consumed energy  in a certain period of time. That period is usually the cycle of measuring and pricing of the spent energy.

New era in renuables

Nowadays that the cost of the produced solar K/wh has decreased immersely and the price of electrical energy has increased in relation to the recent past, net metering is getting more and more appealing to other countries, like Greece.

Release of power limit

Net Metering is legislated without power limit, as it refers to all systems connected to the grid, that is low and medium voltage. Especially the puplic (sectors) services connected to the grid are able to get into high voltage.

Energy Surplus

The energy surplus that derives from counter balance goes into the grid with no obligation to compensate the producer. However, there can be a compensation for the producer for a percentage of the surplus energy by ministry decision. Especially for the public services, up to 20% of the produced energy is compensated by feed-in-tariffs at the time.


Net metering is not only applied on buildings but also on the ground.  The counterbalance is done every four months.

Legislative Framework

With Law 4203 / 2013 (Government Gazette 235A / 11.01.2013) was first instituted that consumers are able to make use of Net Metering. These settings were modified by the Law 4254 / 2014 (Government Gazette 85A / 07.04.2014) and on 30.12.2014 a final decree was signed in which the Special Program for the installation of photovoltaic systems by self-producers to cover their own needs, by applying energy clearing was established.

The program covers fixed photovoltaic systems which are installed in the same or adjacent area with the consuming facilities which they supply, connected to the network. Photovoltaic systems can be installed on buildings or on ground or other structures, including those in the primary sector, according to the current planning legislation.


For the submission of an application, in brief, title deeds (or lease) of property are required as well as written confirmation from the other co-owners (if any) that allow the installation of photovoltaic to the person concerned (eg in case of building). The other documents are related to technical reports, drawings and related affidavits of the supervising engineer. Briefly, the required documents are listed below:

Title deeds (contract on transfer to the land registry or lease) 

Building permit or other documents proving the legitimacy of the building

Sworn statements of the interested

Written permission of co-owners of the site or the general meeting decision of building or relevant affidavits (in common ownership)

Charges and Electricity Conspumtion

The price per kWh paid by a domestic consumer including the Transmission Network Billing, Distribution Network, the Public Service, the Special Consumption Tax, the Special Duty 5%, the ETMEAR and other charges and VAT reaches 0.1927 € / kWh.

Thus removing the SGI charges for the residential consumer netting will be around 0,185 € / kWh including VAT. Correspondingly, the price per kWh paid by small commercial consumers, including above charges reaches 0,165 € / kWh including VAT.

According to the Greek Statistical Authority in 2011 and 2012 the average annual consumption in urban areas of the country was 4000kWh. Multiplying the annual consumption of the above price per kWh paid an average household shows annual electricity cost of € 740 (4.000kWh * 0,185 € / kWh = 740 euros).


The average annual energy production of a P / V system for Athens is about 1350 kWh / kWp. Therefore, to fully cover the annual electric energy of an average household of P / V will need to install a 3,0kWp sized system that will annually produce approximately 4,050 kWh (3 kWp * 1350 kWh / kWp = 4,050 kWh).

Cost and Depreciation of P/V System

Indicatively, the cost of a photovoltaic system for a residential consumer is about 1.700,00 € / kWh and includes everything needed for installation (P / V generators, inverters, foundations, cables, etc.), transport of equipment and the necessary studies. Therefore, an estimated cost of construction of a power station 3.0 kWp will be about 5,100 euros.

Assuming that the cost of connection to the electricity will be about 400 euros, resulting in a final price without VAT 5.500,00 EUR and return on investment through energy savings and compensation will be made in 7.3 years (5,500 euro / 750 euros to be saved per year).


Allows the installation of one or more P / V systems in shared or jointly-owned building space.

-The right of nclusion in the provisions of Net Metering have also the owners of the condo or those with the legal use of these after the grant use of the shared space or jointly-owned by the other co-owners.

Allows the concession space needed for installation of P / V system with the prior written agreement of the owner of the space, in primary or having a legitimate use horizontal ownership of the building where the site is located.

- Each photovoltaic system assigned exclusively to a consumption meter.

- The transition from the existing "Special photovoltaic development program in buildings and especially roofs and roofs of buildings" to the energy netting provisions is allowed. In this case a new Clearing Agreement is concluded, for the remaining period against the 25 years of the original netting agreement.

- The coexistence on the same consumption meter of systems of the existing "Special photovoltaic development program in buildings and especially roofs and roofs of buildings" with systems installed in accordance with the provisions of Net Metering. - A prerequisite for membership to the provisions of this is the full payment of electricity bills or inclusion in regulatory regime.

- The urban planning regulations of installation are already set at the "Special photovoltaic development program in buildings and especially roofs and roofs of buildings" and you can see the full text in the Official Gazette here.

Why Net Metering?

An individual or a professional does not depend on the state to subsidize and to recoup the cost of investment of there being no financial dealings with the state and therefore no revenue from feed-in tariffs. The individual or professional prepays the electrical energy for the next 25 years with low fixed costs and does not care for the annual increases in PPC.

The electricity costs including charges for transport in combination with competitive purchase prices and installation of photovoltaic systems, makes the selection of Net Metering advantageous for the majority of households and businesses.

Motivates to cover a large part of its energy needs, including heating using electricity and gives impetus to alternative and modern forms of heating such as heat pumps, in this way making an extra step to independence from fluctuations in the price of polluting oil or natural gas.

The consumption is close to production by reducing the losses that occur during the transmission of electrical energy. Our country is exempt from energy dependency and cost fluctuations, CO2 emissions are reduced, pressure on the environment and health of inhabitants of neighboring areas in power plants using fossil fuels is reduced.
