Tunari is a commune in the north of Ilfov County, in the midst of rapid residential development, with numerous parcelled plots and new housing developments appearing year after year close to Bucharest. In areas like this, the need for an electrical connection (bransament) is one of the first formalities owners have to deal with: a newly built house or a plot prepared for construction must be connected to the distribution grid before it can be lived in or used. SUN WATT SRL, an ANRE-certified company for design and execution, handles the entire journey of a connection in Tunari, from the technical documentation and the technical connection approval (aviz tehnic de racordare) through to the actual execution of the work and energisation (punere sub tensiune). Beyond individual homes, we also carry out power upgrades (spor de putere) where the existing connection can no longer cope with consumption, as well as work for commercial premises, warehouses or office spaces in the commune's economic areas. The distribution operator in the area is Retele Electrice Romania S.A., and the works are coordinated in accordance with the requirements and stages it imposes. Our team can reach Tunari and the neighbouring localities in Ilfov quickly, thanks to the proximity to Bucharest.
All connection requests in Tunari are filed with Rețele Electrice România S.A. (formerly E-Distribuție Muntenia, part of the Enel group), the operator that issues the technical connection approval (ATR) on the basis of which the work can be carried out. As a predominantly residential commune in Ilfov, the usual solution is the overhead connection, made from the existing low-voltage pole, the most economical option for housing plots; in the areas where the local network has been buried, the connection can also be made underground, so mixed situations occur from one street to another. For a new connection the following are generally required: the urban planning certificate (certificat de urbanism), the property deed or land register extract (extras CF), the site plan (plan de situație) and the connection request (cerere de racordare), documents that we prepare together with the owner. From the filing of the complete dossier to the actual energisation, the indicative duration of the whole process is roughly 4-12 weeks, depending on the operator's pace and the complexity of each case.

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.
