The electricity supply system is divided into two networks, and paragraph 1, item 20 and 22 of the additional provisions of the Energy Act (EA) provides definitions thereto:
- Electricity transmission network is a combination of electric power lines and electric facilities serving for transmission, transformation of the electric power of high voltage to medium voltage and redistribution of electric flows.
- Electricity distribution network is a combination of electric power lines and electric facilities of high, medium and low voltage serving for distribution of electric power.
With regard to the connection to the transmission or to the distribution electricity networks, a more detailed regulation is included in Ordinance No. 6 of 28th of March 2024 on the connection of sites to the electricity networks, issued by the Energy and Water Regulatory Commission (EWRC) (the “Ordinance”).
Who can connect to the network and who can offer the service?
Under article 7, paragraph 2 of the Ordinance, a person who meets the following criteria may be connected to the electricity supply network:
- Has a real right to build on the property where the site is or will be constructed;
- Is the owner, user, or tenant of the site to be connected;
- Has notarized consent from the property owner or a lease agreement with the owner and notarized consent for the placement of a movable structure;
- Has a real right to build on the property or within the site where the site or the non-independent facility/installation is or will be constructed, or has a lease agreement and notarized consent from the owner for the placement of a movable structure .
The cases in which a written request for the connection of a site may be submitted are exhaustively enumerated in Article 7, paragraph 1 of the Ordinance. For example: Article 7, paragraph 1, item 1 provides for the case of “the construction of a new site”, while item 3 covers “the reconstruction of a site pursuant of the Spatial Development Act”.
The electricity supply service is provided by the respective network operator of the electricity distribution network.
What is the connection procedure?
Filing a request for a survey of the conditions for connection
The first phase of the procedure is the survey of the conditions for connection of a site of a customer to the electricity network. For this purpose, a written request has to be submitted to the respective network operator depending on the location of the customer’s site, in a form provided by the network operator.
Art 8, para. 2 of the Ordinance sets out the documents that have to be attached to the application:
- A document certifying a real right to build on the property/site in which the site/non-independent facility/installation is or will be constructed – in cases of construction of a new site, construction of a new site with a non-independent facility/installation, reconstruction of a site, and temporary electricity supply to construction sites;
- A document certifying a real right to build on the property/site, or a notarized consent of the property/site owner, or a lease agreement and a notarized consent of the property/site owner – in cases of reconstruction of a site, increase of the connected capacity, creation of a new site through subdivision, change in the number of phases, construction of new connection facilities, electricity supply to undeveloped property, connection of an existing site, restoration of a terminated connection, additional power supply without a change of category, and commencement of supply from a non-independent facility for own consumption only;
- A notarized consent of the property owner or a lease agreement and a notarized consent of the owner – in cases of temporary electricity supply to movable sites.
When the documents provided are incomplete or do not meet the requirements of the Ordinance, the respective network operator notifies in writing the person filing the application within 5 /five/ working days as of the date of filling (Art 8, para. 3 from the Ordinance)
The person filing the application corrects any incompleteness and irregularities in the documents or provides additionally the required documents and information within 30 days as of the date of receipt of the operator’s notice. The time limit for providing an opinion shall commence from the date on which the additional documents and information are submitted.

On the grounds of art. 140а of the SDA, the applicant may, together with the application for design visa, request to be provided by the respective operators with the output data necessary for the design and for the connection to the technical infrastructure networks, with content in accordance with art. 140, para. 4 of the SDA. In such case, the output data and conditions for connection to the networks, provided by the respective operator, shall be enclosed to the design permit issued as per art. 140а, para. 6 of the SDA.
The respective network operator may refuse to connect a site, fully or partially, to the electric energy network, with justification of the grounds for the refusal, provided that:
- There is technical impossibility to connect the site within the stated deadline for site commissioning;
- When, due to the unavailability of the required capacity, the connection of the site leads to deterioration of the conditions for the supply of electric energy to other customers.
The refusal for connection may be appealed before the Energy and Water Regulatory Commission (EWRC) under the terms and the procedure set out in art. 22 of the Energy Act.
Issuance of a written statement by the operator and signing of a preliminary connection agreement
After the successful completion of Step 1, the network operator prepares and provides to the person that has submitted the request under item 1 above:
- Written statement regarding the conditions for the connection – in all cases; and
- Draft preliminary connection agreement – only in the cases of connection of sites of producers of electricity to the electricity networks.
The written statement regarding the conditions for connection shall be issued by the network operator within a period of 14 to 40 days, counted from the date of receipt of the request, depending on its complexity and specifics of the research.
After the issuance of the statement regarding the conditions for connection, the customer submits to the network operator a work design, part architectural and part electrical installations and installations up to the property’s boundary. The operator shall approve these parts within 7 working days, and if it is necessary to coordinate with another operator, the term shall be extended by the term of the necessary coordination, but not more than 30 days from the submission of the work designs.
In the cases where signing of a preliminary connection agreement is required, the total period for coordination of the conditions for connection and signing of a preliminary agreement is set to 25 days.
The preliminary connection agreement is concluded before the preparation of the investment project for construction or reconstruction of the connected site. Article 17, paragraph 1 of the Ordinance specifies the cases in which, following an opinion, it is necessary to conclude a preliminary connection agreement with the network operator.
