Ulmi is a commune in the north of Giurgiu county, made up of several villages, with a predominantly rural profile and households spread out along the communal and county roads. In areas like these, most connection requests come from new houses under construction, household outbuildings or built-up plots where a home is being raised and there is not yet any electricity supply. Situations also frequently arise involving the replacement of an old connection, the installation of a separate meter after a plot has been split, or a power upgrade (spor de putere) for a household that has increased its consumption. SUN WATT SRL, an ANRE-certified company for design and execution, covers the commune of Ulmi and its constituent villages, travels to the site to assess the distance to the existing grid and prepares the necessary documentation. We work with the distribution operator Retele Electrice Romania S.A. and manage the steps from the grid connection request through to the installation of the meter and energisation, so that owners in Ulmi do not have to run between institutions on their own.
The distribution operator for the commune of Ulmi is Rețele Electrice România S.A. (formerly E-Distribuție Muntenia / Enel), the body through which the connection request is registered and the technical connection approval (ATR) required for any new supply is obtained. Being a rural area with a predominantly overhead network, the usual and more economical solution is the overhead connection, made from the existing pole on the communal or county road, although in sectors where the infrastructure has been reorganised buried sections may also appear. To open the file, the urban planning certificate, the title deed or land registry extract, the site plan and the completed connection application are generally required. From the submission of the documentation to the actual energisation, the indicative duration of the entire process usually falls between 4 and 12 weeks, depending on the operator's schedule and the complexity of the work.
Services available in Ulmi
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).

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.

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.
