Documents needed for an electrical connection: full checklist + the grid connection dossier
If you want to bring power to a house, a plot of land or a building site, the first step is not digging, it is the paperwork. A complete grid connection dossier, correctly submitted to Retele Electrice Romania S.A. (the former operator E-Distributie Muntenia / Enel), means a Technical Connection Approval (ATR) issued quickly and without requests for additional information. Below you will find the complete list of documents needed for an electrical connection (bransament), explained step by step, plus a table with the documents required at each stage.
What the grid connection dossier is and why it matters
The grid connection (racordare) dossier is the set of documents through which you ask the distribution operator to supply electricity to a point of consumption. On its basis, Retele Electrice Romania analyses the request and issues the Technical Connection Approval (ATR) - the document that establishes the technical solution, the approved power and the connection tariff.
In other words, without a complete dossier there is no ATR, and without the ATR the connection contract cannot be signed and the meter cannot be installed. That is why the quality of the dossier decides how quickly you have power.
Checklist: documents needed for an electrical connection
Here is the basic list of documents you need to prepare. Some are mandatory for any connection, others depend on the type of property (house, block of flats, land, building site).
Mandatory documents (individuals)
- The connection request - the operator’s standard form, filled in with the details of the point of consumption and the requested power.
- The identity document of the holder (copy of the ID card).
- Proof of the right of ownership or use of the property: sale-purchase contract, land registry extract (as a rule no older than 30 days), tenancy/loan-for-use contract, etc.
- The urban planning certificate within its validity period (issued by the town hall).
- Site plan and zoning plan, usually at a scale of 1:500 and 1:2000, showing the position of the building and the property boundaries.
- The building permit (where applicable) or proof of the legal existence of the building.
Frequently requested additional documents
- The consent of the owners of land affected by the route, if the connection (bransament) crosses other properties.
- Technical memorandum / power calculation sheet for larger consumers (for example, three-phase with high power).
- Sketch of the utilisation installation or details about important loads (heat pump, EV charging station, industrial hall, etc.).
For legal entities / companies
- Registration certificate (CUI) and the company’s articles of association.
- Power of attorney / mandate for the person submitting the dossier.
- The remaining ownership and urban planning documents, as for individuals.
Practical tip: the land registry extract and the urban planning certificate have validity periods. Submit the dossier while these are still valid, otherwise the operator may ask for them to be updated.
Step by step: how the connection at Retele Electrice Romania works
The connection process is standardised and goes through six stages. The documents above are used in particular at the first stage, but each step has its own requirements.
1. Submitting the connection request with the documents
You gather the documents from the checklist and submit the connection request to Retele Electrice Romania, online or at the customer relations centre. This is where they check whether the dossier is complete.
2. Issuing the Technical Connection Approval (ATR)
The operator analyses the request and issues the ATR, which contains the connection solution, the approved power and the connection tariff - that is, the official fees payable to the operator. This is the moment when you find out the final price of the connection fees.
3. The connection contract and payment of the tariff
On the basis of the ATR you sign the connection contract and pay the tariff that has been set. From this point you can move on to the design and execution part.
4. Designing and executing the connection (bransament)
This is where an ANRE-certified contractor comes in. The technical project is drawn up and the connection (bransament) is actually executed - overhead or underground, single-phase or three-phase. See the solutions on our electrical grid connection page or, for high power, three-phase connection.
5. The DIU dossier (Utilisation Installation Dossier)
After execution, the DIU (Utilisation Installation Dossier / proof of internal installation) is drawn up - the documentation certifying that the internal installation is compliant and can be energised. Details on the DIU dossier page. The DIU is mandatory before the meter is installed.
6. Installing the meter and energisation
In the final stage, the operator installs the meter and energises (punere sub tensiune) the point of consumption. From this moment you have power and you can conclude the supply contract with an energy supplier.
Table: stages, documents and who handles them
| Stage | Main documents / actions | Who handles it |
|---|---|---|
| 1. Connection request | Request, ID card/CUI, proof of ownership, urban planning certificate, plans | Beneficiary (or SUN WATT) |
| 2. ATR | Dossier analysis, issuing of the Technical Connection Approval | Retele Electrice Romania |
| 3. Connection contract | Signing the contract + payment of the connection tariff | Beneficiary |
| 4. Design + execution | Technical project, the connection works | ANRE-certified contractor (SUN WATT) |
| 5. DIU | Utilisation Installation Dossier | Certified electrician/company (SUN WATT) |
| 6. Meter | Meter installation, energisation | Retele Electrice Romania |
How much it costs and how long it takes
Costs have two components: the official fees payable to the operator (set through the ATR) and the labour + materials for design and execution. Below are our indicative prices for the execution part (excluding the operator’s fees):
| Service | Indicative price (from) |
|---|---|
| Connection dossier / project | 900 lei |
| DIU dossier | 1,200 lei |
| Single-phase connection | 1,800 lei |
| Three-phase connection | 2,900 lei |
| Underground connection | 3,500 lei |
| Temporary building-site connection | 2,200 lei |
The final price of the fees always comes through the ATR, depending on the distance to the grid and the requested power. For a quick estimate, use the connection cost calculator or see the full list on the prices page.
SUN WATT handles the entire dossier
The good news: you do not have to go through the bureaucracy on your own. SUN WATT SRL is an ANRE-certified company (execution and design) and can take over the entire process, from the first document to energisation:
