Otopeni is a small town in the north of Ilfov county, developed along the road towards Henri Coanda Airport, where quiet residential streets of houses blend with recent housing developments, freshly subdivided plots and a growing commercial and logistics area. This pace of construction makes the electrical connection (bransament) one of the first concrete steps for anyone putting up a house at the structural stage, finishing a villa or laying the foundations for a business premises. SUN WATT SRL, a firm certified by ANRE for design and execution, manages the entire process in Otopeni: we prepare the connection application and the documents, assist with obtaining the Technical Connection Approval (ATR) from Retele Electrice Romania S.A., carry out the overhead or underground connection and compile the Utilisation Installation Dossier (DIU) for meter installation. For households with ordinary consumption we usually recommend the single-phase option, while for large homes, heat pumps, workshops or commercial premises we recommend the three-phase option. As Otopeni is a locality right on the edge of Bucharest, we travel quickly to your address there for a free on-site assessment, after which we tell you clearly which technical solution suits you and what the next steps are. In short, we spare you the trips to the operator and the bureaucracy and guide you, hassle-free, from paperwork to power at the socket.
All connection requests and the issuance of the technical connection approval (ATR) for Otopeni are handled through Rețele Electrice România S.A., the distribution operator that took over the former E-Distribuție Muntenia (Enel) and manages the network in this part of Ilfov county. Being a town with a mixed configuration, the connection solution varies from one street to another: along the main thoroughfares and in the new residential developments, where the network has been buried, the connection is frequently made underground, while in the areas of older houses and on the plots toward the edge of the locality the overhead connection from the existing pole remains the usual and more economical option. For a new consumption point, the documents typically required are the urban planning certificate, the proof of ownership or the land registry extract, the site plan and the connection application, all of which we prepare and file in full on the client's behalf. From the submission of the complete dossier to the actual energisation, the indicative duration is 4-12 weeks, depending on the operator's schedule and the complexity of the works.

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.
