Voluntari is one of the most sought-after residential addresses in northern Bucharest, a town in Ilfov county that has expanded massively from the Pipera area towards the villa neighbourhoods and new developments on the edge bordering Tunari and Afumati. Here, the pace of construction means the electrical connection (bransament) is one of the first things to tick off: a newly built house on Bulevardul Pipera or in the plots between Soseaua Afumati and Erou Iancu Nicolae needs a permanent grid connection (racordare), while sites still under construction often also require a temporary connection for the duration of the building works. SUN WATT SRL, a firm certified by ANRE for design and execution, covers the whole town of Voluntari and travels on site to assess the property's position relative to the grid and the appropriate technical solution. We prepare and submit the connection application to the operator Retele Electrice Romania S.A. (formerly E-Distributie Muntenia / Enel), monitor the issuing of the Technical Connection Approval (ATR), carry out the overhead or underground connection and prepare the Utilisation Installation Dossier (DIU) required for the meter to be fitted. We recommend a single-phase connection for ordinary household consumption and a three-phase one wherever heat pumps, extensive air conditioning or electric vehicle charging points are installed, all of which are common in the villas in the area. In short, you look after the house, and we look after the paperwork with the operator.
All connection requests and the issuance of the technical connection approval (ATR) are handled through the distribution operator Rețele Electrice România S.A., formerly E-Distribuție Muntenia (part of the Enel group), which manages the local low- and medium-voltage network. Being a town with a mixed urban fabric, the connection solution varies from one street to another: in the densely built-up areas near Pipera, where the network was buried together with the new developments, the connection is frequently made underground, while toward the edge of the locality and on more isolated plots the overhead option from the existing pole remains the usual, more economical choice. For a new connection you typically prepare the urban planning certificate, the title deed or land registry extract, the site plan and the connection request, submitted together as a complete file. From the moment the file is filed until energisation, the indicative duration is roughly 4-12 weeks, depending on the operator's workload and the complexity of the works.
Services available in Voluntari
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.
