Connection for small producers (under 500 kW)

Small producers with electricity production capacity below 500 kW are welcome to join our electricity network. In addition to consuming high-quality electricity the excess electricity can be sold to a suitable electricity seller.

  • Applications up to 15 kW will be issued within 30-60 days
  • The processing of applications from electricity generators above 15 kW may require an increase in generation capacity between the distribution system operator and the transmission system operator. However, this extends the term of the procedure by 90-190 days, i.e. in total it may take 150-340 days to issue a connection bid. In some cases, it is also necessary to pay Elering's processing fee of 1600 EUR + km.
  • Connection application with documentation

    To receive a connection quotation, you have to submit a connection application and other relevant documentation. This can be done by e-mail or regular mail.

    How much does connection cost for a small producer?

    If the transmission capacity of the electricity network is sufficient, the following investments will be required:

  • a meter suitable for production purposes
  • an isolating switch to assure safety
  • If the transmission capacity of the electricity network is not sufficient and needs to be increased, you will also have to pay for the necessary work and equipment and materials.


    The connection fee is always based on actual costs, the exact amount of which and the connection time will be clarified in a connection quotation.

    How long does connection take?

    If no additional work needs to be done in the electricity network, then connection can take

    up to 2 months


    If additional work needs to be done in the electricity network, then connection can take

    up to a year

    Steps to connection

    We can use the connection application to prepare a quote.

    To receive a connection quotation, submit a connection application (doc). After receiving your connection application, we will send you a cost-based contract offer. The connection fee is indicative.

    When preparing a contract offer for an electric power station over 200 kW, Elektrilevi might discover that the throughput into Elering's network has to be increased. In such case, you have to pay Elering's processing fee (1600 euros + VAT) according to the transmission network price list to receive a contract offer. The costs specified in Elering's contract offer will be added to your contract offer.

    The connection costs might increase or decrease in comparison to the original offer during the connection work. The connection fee will be offset with the last instalment after the construction has been completed.

  • If you are not the owner of the property you are using, you also must include the owner's letter of authorisation with your application.
  • In case of a common ownership, the written approval of the co-owner must be included.
  • If you want to join as a producer in an apartment complex or a row house, you must also include the written approval of the apartment association or all co-owners with you application.
  • The forms for letters of authorisation and approvals are available under Conditions and forms »

  • We issue connection offers for electricity producers up to 15 kW within 30-60 days.
  • Processing of applications of electricity generators over 15 kW may require an increase in generation capacity between the distribution system operator and the transmission system operator, which extends the processing time by 90-190 days, i.e. it may take up to 150-340 days to issue a connection offer.
  • We will sign a connection contract and begin the construction work required for the connection once the first instalment has been paid.

    You have 60 days to review the connection offer. If you accept the terms we will start the construction work after the first instalment of the connection fee has been paid. The size of the first instalment is:

  • 50% of the connection fee, if the total connection fee is up to 6,000 euros.
  • 10% of the connection fee, if the total connection fee is over 6,000 euros.
  • To be able to start using your production equipment, send us a report on how the safety settings of the production equipment are set and a copy of the conformity audit report.

    To be able to start using your production equipment, send us the following documents:

  • a report on how the safety settings of the production equipment are set »
  • A valid notice of conformity with all requirements for the electrical system issued by the installer of the equipment, and a copy of the conformity audit report. Details of when an audit is required »
  • You need a network contract to be able to use the network connection.

    We will sign the network contract after you have submitted all the necessary documents and paid the bills. You need a network contract to be able to use the network connection, including to transmit electricity and measure its consumption.

    To buy and sell electricity, you will have to sign an electricity contract with an electricity seller. You will find information on electricity sellers on our website.

    Frequently asked questions

    As an electricity producer, you can join on your property if you submit the producer's connection application together with additional documents to us.

    List of required documents:

  • for a producer with a power of less than 500 kW >>
  • for a producer with a power from 500 kW >>
  • Based on the request, we will make you a price offer, which we will send:

  • Within 60 days if the application is submitted for a device with a power of up to 15 kW
  • Within 150 days if the application is submitted for a device with a power of more than 15 kW
  • The issuance of tenders has prolonged due to the increased number of electricity producers' connection applications.

    When preparing the offer, we immediately take into account that it would be possible to make changes in the electricity network of the distribution network company and/or the transmission network company. The development and coordination of such technical solutions will take time.

    We issue electricity producer offers:

  • for a production unit with a power of up to 15 kW - within 60 days
  • for a production unit with a capacity of more than 15 kW - within 150 days, as it requires coordination with Elering.
  • To change the terms of the subscription agreement, an application must be sent to elektritootjad@elektrilevi.ee

  • If the technical solution remains the same, an annex to the joining agreement will be concluded to change the conditions.
  • If it turns out that the technical solution also needs to be changed in order to implement the change, the manufacturer must start the connection process from scratch.
  • Electricity generation equipment may only be connected to the electricity grid after the electricity or micro producer's network contract has been signed bilaterally.

    Renewable energy subsidies are handled by the transmission system operator Elering AS. See detailed information at homepage of Elering.
