Gruiu is a commune in the northern part of Ilfov County, stretching along the Ialomita valley and near the Gruiu and Snagov lakes, with constituent villages such as Lipia, Santu Floresti and Silistea Snagovului. It is a predominantly rural and leisure area where, alongside traditional households, an increasing number of holiday homes, permanent residences and plots subdivided on land that has never had an electricity supply have appeared. This is precisely why the most common situations here are the connection from scratch for a house built on a vacant plot, the temporary site connection (bransament provizoriu) during the construction period and, subsequently, its conversion into a permanent connection. SUN WATT SRL, an ANRE-certified company for design and execution, covers the entire commune of Gruiu and its associated villages, travelling on site to measure the distance to the nearest point in the network and to determine whether the connection is made overhead, from an existing pole, or underground. On the more isolated plots, located at a distance from the network, a short grid extension may be required, an aspect we identify in good time so that no surprises arise. We handle the entire administrative and technical chain: the grid connection (racordare) request with the relevant documents, monitoring the Technical Connection Approval (ATR) issued by Retele Electrice Romania, the connection contract, the design and execution itself, the Utilisation Installation Dossier (DIU) and preparation for fitting the meter. For ordinary household consumption we usually recommend the single-phase option (230V), while for large homes, heat pumps or workshops, the three-phase option (400V).
All connection requests and the technical connection approval (ATR) for projects in Gruiu are filed and obtained through the distribution operator Rețele Electrice România S.A., formerly E-Distribuție Muntenia (Enel), which manages the low-voltage network in the area. As a predominantly rural and leisure-oriented commune, the common and more economical solution remains the overhead connection drawn from the existing pole of the street network, though in newer parcelled plots or where the infrastructure is buried, underground connections may also occur, resulting in mixed arrangements depending on the layout of each village. For a complete dossier the documents usually required are the urban planning certificate, the proof of ownership or the land registry extract, the site plan and the connection request. As a guideline, from the filing of the dossier to energisation the interval is 4-12 weeks, depending on the operator and the complexity of the works.
Services available in Gruiu
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.
