Chiajna stretches from the western edge of Bucharest, as an extension of the Militari district, and includes the villages of Rosu and Dudu, which in recent years have become some of the most sought-after residential areas near the Capital. The rapid densification of plots and the continuous appearance of single-family houses, duplexes and small developments mean that grid connection (racordare) to the electricity network is a step constantly requested by property owners. Most often, people contact us when they have finished the structure of a house on a plot that was never supplied, when they need a site-organisation connection before starting works, or when the network needs to be extended a few dozen metres to a newly subdivided plot. Alongside new connections, in Chiajna we also frequently encounter requests for a power upgrade (spor de putere) or for switching from 230V to 400V, for households that have installed heat pumps, photovoltaic panels with a three-phase inverter or car charging stations. SUN WATT SRL, a company certified by ANRE for design and execution, covers the entire commune, including Rosu and Dudu, and comes to your address to measure the distance to the connection point and determine whether the right solution is overhead or underground. We prepare and submit the documentation to Retele Electrice Romania S.A., follow up on the Technical Connection Approval (ATR) and see the work through to the installation of the meter, so that you can focus on your house rather than on trips to the operator.
The distribution operator for the area is Rețele Electrice România S.A. (formerly E-Distribuție Muntenia, part of the Enel group), through which all connection requests are filed and the technical connection approval (ATR) is obtained. In Chiajna the technical situation is usually mixed: in the villages of Roșu and Dudu, as well as along roads with an existing overhead network, the connection is most often made overhead, from the nearest pole, this being the faster and more economical solution, while on the plots within recent developments, where the local network has been buried, the connection is carried out underground. For a new connection, the dossier typically includes the urban planning certificate, the title deed or land registry extract, the site plan and the connection request. As a guide, from filing the complete dossier to energisation it usually takes around 4-12 weeks, the interval varying according to the operator and the complexity of the works.
Services available in Chiajna
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.
