What is RAE?
The Regulatory Authority for Energy (RAE), which was set up in July 2000, is an independent administrative authority assigned with the task of monitoring the energy market, as it develops – so univocally in the Greek market – and its operation and development compared to foreign energy markets, and in particular the ones with which it is interconnected. RAE was established by L. 2773/1999, in the framework of harmonization with the directives 2003/54/EC and 2003/55/EC for electricity and natural gas. By the above law, its internal regulation (P.D. 139/01), and mainly by the amendments of L. 2773/1999 that followed, RAE has acquired the competency of monitoring and controlling all sectors of the energy market, namely, electricity generation from conventional fuels, renewable energy sources and natural gas. Furthermore, RAE has specific responsibilities regarding the oil products market. (Source: RAE website).

What is the Solemn Declaration by the Installation Electrician (SDIE) and when is it required?
The Solemn Declaration by the Installation Electrician (SDIE) aims at the observation of the regulations and the legislation concerning electrical installations, in order for such installations to be manufactured and maintained in a truly safe and functional condition for their owners or users, and to prevent accidents (electrocution, fires due to electrical causes) that occur due to electricity.
The Solemn Declaration by the Installation Electrician has recently been changed and modified according to Resolution no. F.50/503/163 (Official Gazette of the Hellenic Republic 884 B 15.05.2011), and the full application of the new Solemn Declaration has been effective since 01.11.2011. This Declaration is required by law, and without it there can be no supply of electricity to either a new or an old installation whose electrical supply has been cut off because it needs to be re-inspected.
This Declaration is drafted by the electrician, who declares the following:
- The installation described in the contents is constructed pursuant to the legislation in force regarding electrical installations.
- The installation has been inspected by the electrician signing the declaration, also according to the legislation in force, in order to confirm that it is safe.
- An existing installation has been re-inspected; also, the declaration confirms that it is safe.
- The installation is delivered by the electrician to its owner or user and provides him or her with the statutory safety against electrocution, fire and malfunction.
This Declaration is necessary because:
– It helps in distinguishing among owners, users and electricians who fail to observe the law regarding electrical installations, and it also forces them to take responsibility.
– It helps in assigning responsibilities in the event of accidents (electrocutions or fires due to electrical causes).
Is there a requirement for the Solemn Declaration by the Installation Electrician to be renewed?
There is a legal obligation concerning its renewal. According to Ministerial Resolution no.F.7.5/1816/88 on 27/02/2004, published in FEK no. 470 on 05/03/2004, this Solemn Declaration is mandatory for purposes of initial inspection and re-inspection.
The initial inspection must be performed prior to the initial supply of electricity to an installation, or after any extensive modifications. Re-inspections must be performed in intervals, which differ according to the type of installation, and these intervals are:
- For residences and similar spaces, at least every 14 years.
- For indoor occupational spaces not containing flammable materials, at least every 7 years.
- For indoor occupational spaces containing flammable materials, at least every 2 years.
- For entertainment venues and public gathering places, at least once a year.
- For outdoor occupational installations (swimming pools, marinas, camping spaces) at least once every year, and in cases of interruption of electricity supply, prior to reconnection.
- For all the above categories, re-inspection is mandatory in cases of change in use of the installation.
- For all the above categories, re-inspection is mandatory if the installation has been damaged due to natural disasters (floods, earthquakes).
- After serious accidents or events (fire, electrocution).
