Joița is a commune in the north of Giurgiu County, set within the metropolitan area of Bucharest, near the A1 motorway, and made up of several villages such as Joița, Bâcu, Cosoba and Săbăreni. More and more houses are being built on the plots resulting from land subdivisions and on the open land at the edge of the villages, and every new home needs an electrical connection (bransament) before it can be lived in. SUN WATT, a company certified by ANRE for design and execution, covers the entire commune of Joița and its constituent villages, travelling on site to measure the distance to the existing grid and to determine the right solution. Here we come across typical situations: a connection from scratch for a newly built house, a temporary site connection during the works followed by the permanent one, or the switch from single-phase (230V) to three-phase (400V) when heat pumps, workshops or car charging stations come into play. The local distribution operator is Retele Electrice Romania S.A. (formerly E-Distributie Muntenia / Enel), and we take over the grid connection (racordare) application, follow up on the issuing of the Technical Connection Approval (ATR), design and carry out the connection, and prepare the Utilisation Installation Dossier (DIU) up to the installation of the meter. We work on a turnkey basis, from the dossier to the pole, so that you only have to deal with your own paperwork.
All connection requests, together with obtaining the technical connection approval (ATR), are filed and handled through the distribution operator Retele Electrice Romania S.A., formerly E-Distributie Muntenia (Enel), which manages the network across the commune. Since the constituent villages retain their rural character, the usual solution remains the overhead connection made from the nearby low-voltage pole, the most economical option for scattered households, while on a few more developed stretches an underground connection may also be found where the local network has been buried. For a new connection, the documents typically required are the urbanism certificate, the proof of ownership or the land registry extract, the site plan, and the connection application. From the submission of the complete dossier to the actual energisation, the indicative duration falls between 4 and 12 weeks, depending on the operator's schedule and the complexity of the work.
Services available in Joița
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 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. 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.
