Roata de Jos is a commune in the north of Giurgiu county, in the plains area of Muntenia, made up of several villages, among them Roata Mica, Sadina and Cartojani, crossed by the DN61 national road that links the area to Bolintin and to the capital. Being a predominantly rural settlement, with scattered households and plots resulting from land subdivisions, the works we most often encounter here are the connection (bransament) for a house recently built on a plot without a supply, the grid connection (racordare) of a household annex or a small workshop, and the power upgrade (spor de putere) at a household that has added new equipment. SUN WATT, a company certified by ANRE for design and execution, serves Roata de Jos and its attached villages, travelling on site to check where the nearest connection point is and which technical solution is the right fit. We take over the entire process on your behalf: we submit the grid connection (racordare) request with the necessary documents, we follow up on the issuing of the Technical Connection Approval (ATR) from the operator Retele Electrice Romania (formerly E-Distributie Muntenia / Enel), we design and install the connection, either single-phase (230V) for ordinary household consumption or three-phase (400V) for higher power, and we prepare the Utilisation Installation Dossier (DIU) for fitting the meter. You are left with a single conversation, and we handle the rest of the trips to the operator.
The distribution operator for this area is Retele Electrice Romania S.A. (formerly E-Distributie Muntenia / Enel), the company through which all connection requests are filed and the ATR is obtained, the technical connection approval that sets out the concrete conditions of the works. As is typical for a plains commune with households spread across large plots, the most commonly encountered solution is the overhead connection, branched from the existing low-voltage network on the poles along the lane, a more economical option than underground works and well suited to the distances usual here. For a new connection, the file generally includes the urban planning certificate, the title deed or land registry extract, the site plan and the connection request, documents that we prepare and submit on the beneficiary's behalf. The indicative duration, from registration of the file to energisation, normally falls between 4 and 12 weeks, depending on the operator's schedule and the complexity of the case.
Services available in Roata de Jos
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.
