Colibași is a commune in the north of Giurgiu County, within the zone of influence of Bucharest, with a predominantly residential character and households spread across individual plots. In localities such as this, the most frequent requests come from owners of new houses who need an electrical connection (bransament) in order to connect their home to the grid, but also from those who are building and require a temporary supply for the duration of the works. There are also cases where the aim is to switch from a single-phase to a three-phase connection, for households that use higher-consumption equipment, or to replace old installations that no longer comply. SUN WATT SRL, a company certified by ANRE for both design and execution, covers the commune of Colibași and its belonging villages, travelling on site for assessment. We prepare the technical documentation required for the connection dossier, submit it and manage the relationship with the distribution operator Retele Electrice Romania, and carry out the actual works through to energisation (punere sub tensiune), so that the owner does not have to handle the bureaucratic and technical steps alone.
The distribution operator serving this area is Retele Electrice Romania S.A. (formerly E-Distributie Muntenia, part of the Enel group), and it is through this operator that all connection requests are filed and the technical connection approval (ATR) is obtained. Being a commune with a predominantly rural fabric and households spread over individual plots, the usual solution remains the overhead connection, made from the existing pole of the low-voltage network, the most economical and fastest option for this type of locality; only in areas where the network is laid underground is a buried connection used. For a new connection, a standard set of documents is generally required: the urban planning certificate, the property deed or land registry extract, the site plan, and the connection request. As a guideline, roughly 4-12 weeks pass from the filing of the complete dossier to the actual energisation, the interval varying depending on the operator's workload and the complexity of the work.
Services available in Colibași
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.

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.
