Oinacu is a lowland commune in Giurgiu County, stretching along the northern bank of the Danube just a few kilometres from the town of Giurgiu, made up of the villages of Oinacu, Comasca and Branistea. The area is dominated by scattered households, farmland and plots towards the edges of the villages, where new houses, outbuildings and small leisure and fishing developments are gradually appearing along the Danube. In situations like these, every building needs an electrical connection (bransament) to be brought into service, and the rural character means that the distance from the property to the nearest point on the grid is sometimes greater, which can call for a technical solution designed on an individual basis. SUN WATT, a firm certified by ANRE for design and execution, serves Oinacu and its constituent villages, travelling out to site to assess the location, access and position relative to the grid. We carry out single-phase connections (230V) for households with ordinary domestic consumption and three-phase connections (400V) for those with heat pumps, agricultural machinery, workshops or vehicle charging stations. The grid operator in the area is Retele Electrice Romania S.A. (formerly E-Distributie Muntenia / Enel), and we manage the relationship with them on your behalf: we draw up the grid connection (racordare) application, follow through the issuing of the Technical Connection Approval (ATR), design and execute the connection and prepare the Utilisation Installation Dossier (DIU) up to the point of fitting the meter. In this way, residents of Oinacu receive a turnkey job, from the file to the pole, without repeated trips to the counter.
The distribution operator for the Oinacu commune area is Rețele Electrice România S.A. (formerly E-Distribuție Muntenia / Enel), the company with which all connection requests are filed and through which the technical connection approval (ATR) required for any new property is obtained. Given the predominantly rural character of the villages of Oinacu, Comasca and Braniștea, the usual solution remains an overhead connection made from the existing low-voltage network pole, the most economical option for scattered households; where the network is already buried or in the more compact areas, underground connections may also occur, resulting in mixed situations. A complete file typically requires the urban planning certificate (certificat de urbanism), the title deed or land register extract (extras CF), the site plan, and the connection request. From the filing of the dossier to actual energisation, the indicative duration is roughly 4-12 weeks, depending on the operator and the complexity of the work.

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.
