SUN WATT is an ANRE-attested firm providing three-phase electrical connections (400V) in Bucharest, Ilfov and Giurgiu, with prices starting from 2,900 lei. A three-phase connection is required whenever you have high consumption or powerful equipment — for example heat pumps, workshops, machine tools or car charging stations. We take care of everything, from preparing the documentation and obtaining the Technical Connection Approval (ATR) right through to energisation, usually within 4 to 12 weeks. The grid operator for the region is Retele Electrice Romania (Distributie Energie Electrica Romania).
When you need it
A three-phase connection is suitable for any situation that requires power above roughly 11 kW: heat pumps, industrial workshops, electric motors, rapid EV charging stations, farms, and commercial premises with several consumers running at the same time. If your equipment is rated for 400V or your overall load is too great for a single-phase supply, a three-phase connection is the right choice.
How it works — step by step
- Free assessment and connection request. We determine the power you need and the appropriate type of connection, then prepare the documentation for the grid operator, Retele Electrice Romania (Distributie Energie Electrica Romania).
- Obtaining the Technical Connection Approval (ATR). The ATR (Technical Connection Approval) sets out the technical conditions and the connection tariff for your three-phase connection. This stage usually takes several weeks.
- Connection contract and design. Once the connection tariff has been paid, we design the three-phase installation — including the cable, the distribution board and the protections — in accordance with the standards in force.
- Execution of the three-phase connection. We install the overhead or underground connection, the distribution board and the protections, all correctly sized for your load.
- DIU file, meter and energisation. We prepare the DIU (Utilisation Installation Dossier), which allows the meter to be fitted and the power to be switched on.
Required documents
- Identity document
- Property deed (an up-to-date land registry extract)
- Urban planning certificate
- Location and site (cadastral) plans
- Building permit (where applicable)
