Technical Connection Approval (ATR) — Full Turnkey Dossier

The Technical Connection Approval (ATR) is the document issued by the distribution operator (Retele Electrice Romania in the Bucharest–Ilfov–Giurgiu area) that sets the technical conditions and the connection tariff for joining the electricity grid. It is obtained through a connection application with supporting documents, and the operator issues it within 30 calendar days of the complete file being submitted, according to the timelines published by Retele Electrice Romania. At SUN WATT, an ANRE-certified company, we prepare and submit the ATR file from 350 lei in 2026 (consultancy and submission, excluding operator fees), with the final connection tariff being the one set in the ATR.

The Technical Connection Approval (ATR — Aviz Tehnic de Racordare) is the document issued by the distribution operator (Retele Electrice Romania / Distributie Energie Electrica Romania, for the Bucharest–Ilfov–Giurgiu area) that sets out the technical conditions and the connection tariff for hooking up to the electricity grid.

When you need it

You need an ATR whenever you want a new connection to the electricity grid or a change to an existing one: a connection for a house, flat, warehouse or commercial space, a temporary site (construction) connection, a power increase (capacity upgrade), or a switch from single-phase to three-phase supply.

How it works — step by step

  1. Assessment and preparation of the connection application. Together we determine the power you actually need and the right solution (single-phase 230V or three-phase 400V). We prepare the connection application and check which documents are required in your specific case, at no cost.
  2. Compiling and submitting the dossier. We complete the dossier with the identity documents, ownership documents and technical documentation (site plan, planning certificate where applicable) and submit it to Retele Electrice Romania on your behalf.
  3. Operator review and issuance of the ATR. The operator reviews the application and issues the Technical Connection Approval (ATR), which sets out the technical conditions, the approved power and the connection tariff. We follow up on the dossier and respond to any requests for additional information.
  4. Handover of the ATR and next steps. We clearly explain the contents of the ATR and the connection tariff to you. From here we move forward with the connection contract, the design and execution of the connection, and the DIU (Utilization Installation Dossier — Dosarul Instalatiei de Utilizare) — everything turnkey, right through to energisation.

FAQ — Technical Connection Approval (ATR)

What is the Technical Connection Approval (ATR)?

The ATR (Aviz Tehnic de Racordare) is the document issued by the distribution operator — Retele Electrice Romania in the Bucharest, Ilfov and Giurgiu area — which sets out the technical conditions and the connection tariff for hooking up to the electricity grid. It is the mandatory step before the connection contract and the execution of the connection itself.

How much does it cost to obtain the ATR?

Our assistance for obtaining the ATR (consultancy, dossier preparation and submission) starts from 350 lei, excluding the operator's fees. The actual connection tariff is set by the operator within the ATR itself and is paid separately.

How long does it take to receive the ATR?

As a rough guide, the operator issues the Technical Connection Approval within a few weeks of the submission of a complete dossier. A correctly prepared dossier, put together by an ANRE-certified company, reduces the risk of additional requests and delays.

What documents do I need to obtain the ATR?

As a rule: your identity document, proof of ownership (land registry extract), the planning certificate (for construction works), the site and location plans, plus the connection application. We take care of preparing and submitting the entire dossier.

Can I prepare the ATR dossier myself?

Yes, but an incomplete or incorrectly prepared dossier frequently leads to requests for additional information and to wasted time. As an ANRE-certified company, we prepare the documentation in line with the operator's requirements and follow up on the dossier.

What happens after the ATR is obtained?

Once the ATR has been issued, you sign the connection contract and pay the tariff set out in it; the connection is then designed and executed by the ANRE-certified company, and the DIU (Utilization Installation Dossier — Dosarul Instalatiei de Utilizare) is prepared.

Who issues the ATR in Bucharest, Ilfov and Giurgiu?

The electricity distribution operator for the Bucharest–Ilfov–Giurgiu area (Muntenia) is Retele Electrice Romania S.A. (formerly E-Distributie Muntenia / Enel). It reviews the connection application and issues the Technical Connection Approval; we prepare the dossier and manage the relationship with the operator.
