1 Decembrie is a commune in the south of Ilfov County, on the border with Giurgiu County and close to the Bucharest ring road, an area of ongoing residential development where new houses and parcelled plots frequently appear, all needing a properly set-up electrical connection (bransament). For property owners in 1 Decembrie, the critical moment usually comes when construction reaches the stage where permanent power is required: the home is built, but without a grid connection (racordare) the final acceptance cannot be obtained and the property cannot actually be lived in. SUN WATT SRL, a company certified by ANRE for both design and execution, steps in precisely in these situations typical of the commune: new connections for individual houses, connections for site organisation facilities, replacement of old connections, or increasing the contracted power (spor de putere). We travel to all parts of the commune and take care of dealing with the distribution operator Retele Electrice Romania S.A., so that clients in 1 Decembrie do not have to chase after approvals and forms themselves. You can rely on advice before you begin and on work carried out in accordance with the regulations in force.
All connection requests in 1 Decembrie are filed with Rețele Electrice România S.A., the distribution operator (formerly E-Distribuție Muntenia / Enel), which issues the ATR, the technical connection approval without which the installation cannot be energised. Given the locality's rural, commune character, the usual solution remains the overhead connection, run from the existing pole of the street network, the most economical option for individual plots and houses; however, where the local network is laid underground, buried connections are also carried out, so in the more developed areas mixed situations occur. To open the file, the documents typically required are the urban planning certificate (certificat de urbanism), the proof of ownership or land registry extract, the site plan and a correctly completed connection request. As an indication, from filing the dossier to actual energisation the total duration falls within 4-12 weeks, depending on the operator's workload and the complexity of the connection.
Services available in 1 Decembrie
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.
