Self-consumption

With the installation of a Photovoltaic (PV) system you can take advantage of the abundance solar energy to produce your own electrical energy in order to be independent and set the amount paid to bills of electivity almost to zero. In this way you will become a self consumer meaning that you will produce the energy that you consume and above all this energy will be clean and green energy.
The possibilities offered for self-production / self-consumption of electricity through a station of Renewable Energy Sources (photovoltaic and not only), are many and varied, depending on the needs, conditions and type of consumer.

The first option is netting between produced and consumed energy (known as energy netting or Net-Metering), where it allows the consumer to cover all or part of their electricity consumption, while at the same time being able to use the grid.This scheme, allows you to use the green energy produced by the PV systems for your own consumptions and to use the grid as storage for the excess energy produced. The term “net” refers to the fact that you will be charged only for the difference between energy you consume and the energy that PV systems produces. And this refers to a 3 years cycle. In case that the energy produced by the PV systems exceeds your own consumptions, the excess solar energy is fed to the grid and it will be subtracted by the energy you derive from the grid at another time of the year (for the next 3 years).

The second option is the simultaneous energy netting, i.e. self-production in real time, with the sale of excess energy (known as Net-Billing), where self-producers or self-consumers are given the possibility to install a photovoltaic system for simultaneous use of of produced energy for consumption in their facilities, while the surplus energy can either be stored for future use or sold. The sale of excess energy is done through power purchase agreements, electricity suppliers and trading agreements, without intermediation. Net-billing can also be virtual (virtual net-billing), where the production station is at a different point in relation to consumption.

A third option for consumers who are in the same building, is to jointly install an energy compensation system (Net-Metering) and share, through a simple mutual agreement, the energy produced, offsetting it with their consumptions.

All the above options can be combined with storage systems (batteries).

In addition to the above, consumers, depending on the category they belong to, can participate in collective schemes of either virtual net-metering or virtual net-billing. Specifically:

• Natural persons can participate in virtual net-metering schemes as members of Citizens’ Energy Community or Renewable Energy Community or Energy Community of Law 4513/2018,
• Local Government Organizations (LGAs) can install virtual net-metering photovoltaic stations with a power equal to one hundred percent (100%) of the sum of the agreed power of the consumption benefits to be offset, for municipal companies public benefit purpose
• Farmers, registered in the Register of Farmers and Agricultural Holdings of Law 3874/2010 (Α΄ 151) for facilities of agricultural holdings of Law 3874/2010 and agricultural uses can install photovoltaic stations of virtual energy compensation (virtual net-metering) with a power of up to 100 kW.
• Businesses can participate in virtual net-billing schemes as members of Citizens’ Energy Community or Renewable Energy Community or Energy Community of Law 4513/2018.

The Renewable Energy Community (K.A.E.) is an urban cooperative. Members of K.A.E. are natural persons, OTAs, Small and Medium Enterprises and agricultural cooperatives. The minimum number of members of K.A.E. are 30 or 15 members, in case at least 15 Small and Medium Enterprises participate.

The Energy Community of Citizens (E.K.P.) is an urban cooperative. Members of E.K.P. are natural persons, OTAs, public and private legal entities and businesses. The minimum number of members of the E.K.P. are 30 or 15 members, in case at least 15 legal entities of private or public law participate, or 3 members if 1 OTA participates. and the other 2 members are either O.T.A. or businesses.

Both K.A.E. and E.K.P. can install virtual energy offsetting photovoltaic stations that also include storage systems, to meet the energy needs of their members who are residential consumers and consumers living below the poverty line.
