Adunații-Copăceni is a commune in the north of Giurgiu County, stretching along the road towards Giurgiu (DN5), just a few kilometres from the southern edge of Bucharest, which makes it highly sought after for house construction. The commune comprises several constituent villages, including Dărăști-Vlașca, Mogoșești and Varlaam, where households are spread out and parcelled plots on former agricultural land are appearing more and more often. In such situations, the most frequent requests we receive are for connections (bransament) for a new house without a supply, temporary site connections during construction, and switches from single-phase (230V) to three-phase (400V) when a heat pump, a workshop or a vehicle charging station is being installed. SUN WATT SRL, an ANRE-certified company for design and execution, covers the entire commune of Adunații-Copăceni and its associated villages, travelling to the site to measure the distance to the nearest pole and to determine whether the appropriate solution is overhead or underground. The distribution operator for this part of Giurgiu County is Retele Electrice Romania S.A. (formerly E-Distributie Muntenia), and we take on the entire bureaucracy: the grid connection request, obtaining the Technical Connection Approval (ATR), the design and execution of the connection, the preparation of the Utilisation Installation Dossier (DIU) and getting everything ready for the meter to be fitted. In practice, you receive a turnkey solution, from paperwork to pole, without having to make the trips to the operator yourself.
All connection requests and the issuing of the technical connection approval (ATR) are handled through the distribution operator Rețele Electrice România S.A., formerly E-Distribuție Muntenia (Enel), which is responsible for the grid in this part of Giurgiu county. Being a predominantly rural commune, with plots laid out along the roads and lanes of its component villages, the usual solution remains an overhead connection drawn from the existing low-voltage pole, which is more economical and quicker to carry out, although on the newer or upgraded sections an underground variant may also be encountered. For a complete file the documents typically required are the urban planning certificate, the property deed or the land registry extract, the site plan and the connection request. From the filing of the documentation to the actual energisation, the indicative duration falls between 4 and 12 weeks, depending on the operator's deadlines and the complexity of the work.
Services available in Adunații-Copăceni
Single-phase connection
A single-phase electrical connection (230V) is the standard supply for homes with typical consumption, usually approved up to around 11 kW. SUN WATT, an ANRE-certified company, handles the entire process from start to finish, with 2026 prices starting from 1,800 lei. The timeline from file submission to energisation is typically 4-12 weeks, with the final cost confirmed through the ATR (Technical Connection Approval).
Three-phase connection
A three-phase electrical connection (400V) is needed for high consumption or powerful equipment such as heat pumps, workshops, machine tools or EV charging stations. SUN WATT, an ANRE-attested firm, handles the entire process — from the paperwork and the Technical Connection Approval (ATR) through to energisation — typically within 4 to 12 weeks. Prices start from 2,900 lei.
Temporary site connection
A temporary site connection supplies your construction site with power throughout the building works, before the permanent connection is installed. It is obtained through a connection application and a Technical Connection Approval (ATR) from Retele Electrice Romania, and is carried out by an ANRE-certified company. Prices start from 2,200 lei (labour plus materials, excluding the operator's fees), with the whole process usually taking around 4-12 weeks.
Grid connection
Electricity grid connection is the process of linking a plot, house or new premises to the electricity distribution network so you can have your own meter and power at the socket. The process involves six stages: the connection request, the Technical Connection Approval (ATR), the connection contract, the ANRE-certified service line works, the Utilization Installation Dossier (DIU) and meter installation. In Bucharest, Ilfov and Giurgiu the network operator is Retele Electrice Romania S.A. (Distributie Energie Electrica Romania). The service starts from 900 lei (labour, excluding operator fees) and typically takes 4 to 12 weeks.
Power increase
A power increase means raising the approved electrical power at your existing connection when your current installation can no longer cope with your consumption. It is carried out through an application to the operator Retele Electrice Romania (Distributie Energie Electrica Romania), followed by a new ATR (Technical Connection Approval), a contract and any required connection changes. In 2026, labour starts from 350 lei (excluding operator fees), with an indicative duration of 4 to 12 weeks.
Prosumer / solar connection
Connecting a photovoltaic system to the grid as a prosumer means submitting a connection application to Retele Electrice Romania (Distributie Energie Electrica Romania). SUN WATT, an ANRE-certified company, prepares the full dossier, obtains the ATR (Technical Connection Approval), and coordinates the installation of a bidirectional meter so you can feed your surplus energy back into the grid.
