Berceni is a commune in the south of Ilfov County, bordering the edge of Bucharest in the area of Sector 4 (the district of the same name) and located close to Popesti-Leordeni. Its character has changed noticeably in recent years: alongside the older households in the village centre, new plot divisions have appeared, with more and more single-family homes being built on them, which means frequent requests for connection to the electricity grid. In these cases, a newly built house has no power supply of its own, and the first concrete step towards moving in is the definitive electrical connection (bransament); for the construction period, a temporary connection is often useful too, supporting the works until completion. SUN WATT, a company certified by ANRE for design and execution, takes on the entire process in Berceni: we submit the connection application with the required documents to the operator Retele Electrice Romania S.A. (formerly E-Distributie Muntenia), follow up on the issuing of the Technical Connection Approval (ATR), sign the connection contract, design and build the connection — overhead or underground, depending on the position relative to the grid — and prepare the Utilisation Installation Dossier (DIU) for fitting the meter. For plots further from the existing grid, we assess the connection distance on site, as this can influence the technical solution and the cost confirmed through the ATR. We travel throughout the commune and its dependent villages, recommending a single-phase connection (230V) for ordinary domestic consumption or three-phase (400V) where there are heat pumps, workshops or car charging stations, so that owners in Berceni do not have to manage the administrative steps on their own.
For the localities in this area, the distribution operator is Rețele Electrice România S.A. (formerly E-Distribuție Muntenia, part of the Enel group), to which all connection requests are submitted and through which the ATR (technical connection approval) is obtained. Given the predominantly rural character of the commune, the usual and more economical solution is the overhead connection, made from the existing pole on the low-voltage network, although in the more densely subdivided areas, where the local grid is buried, the underground option may also be encountered. The technical dossier generally requires the urban planning certificate (certificat de urbanism), the proof of ownership or land registry extract (extras CF), the site plan (plan de situație) and the connection application (cerere de racordare), correctly completed and filed together. As a rough estimate, between 4 and 12 weeks may pass from filing the documentation to the actual energisation, depending on the operator's workload and the complexity of the work.
Services available in Berceni
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.
