Cernica is a commune in the eastern part of Ilfov County, known for Cernica Monastery, the nearby lake and forest, and made up of several villages such as Cernica, Balaceanca, Caldararu, Tanganu and Posta. It is precisely this character as a green, quiet area close to Bucharest that attracts more and more owners building a home or a holiday house on plots parcelled out towards the lake and the forest, where mains electricity often does not yet exist. In these situations the need arises for a brand-new connection (bransament) from scratch, as well as a temporary site connection for the duration of the works, or a switch from single-phase (230V) to three-phase (400V) when installing a heat pump, a workshop or an EV charging station. SUN WATT SRL carries out electrical connections and grid connections in Cernica and its associated villages, travelling to the site to assess the location and the distance to the network of the operator Retele Electrice Romania. On more isolated plots, towards the lake or the edge of the forest, the distance to the network may call for a particular technical solution, which we work out together following the assessment. As a company certified by ANRE for design and execution, we handle all the paperwork and provide you with a turnkey solution, from the file to the pole, without you having to chase after documents.
The distribution operator that manages the network in Cernica is Rețele Electrice România S.A. (formerly E-Distribuție Muntenia, part of the Enel group), and it is through this operator that all connection requests are filed and the ATR, the technical connection approval, is obtained. Being a commune with villages located predominantly in a rural area, the usual and more economical solution remains the overhead connection made from the existing pole of the local network, although on some more developed sections there may also be portions of buried network, in which case the underground option is used. For a new connection, the dossier typically includes the urban planning certificate, the proof of ownership or the land registry extract, the site plan and the connection request, documents without which the process cannot be started. As a guideline, from the filing of the complete dossier to the actual energisation it usually takes between 4 and 12 weeks, the duration varying depending on the operator and the complexity of the work.
Services available in Cernica
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.
