As an electricity transmission system operator (TSO), AS Augstsprieguma tīkls has a permanent obligation, subject to the scope and term of its licence, to ensure the network members have the necessary connections to the transmission system or the necessary changes to the permitted capacity of the existing connection consistently with the regulations issued by the Public Utility Regulatory Commission (the Regulators).
The regulations issued by the Regulator:
- Regulations for a System Connection for Participants of an Electricity System
- Regulations Regarding System Connection for Electricity Producers
The users of the electricity transmission system are required to comply with Commission Regulation (EU) No. 2016/1388 of 17 August 2016 on establishing a network code on demand connection.
Electricity producers must comply with the requirements of the Commission Regulation (EU) of 14 April 2016 establishing a network code on requirements for the grid connection of generators.
Under the procedure prescribed by the Cabinet, the end-user has the right to submit an application for special connection to the transmission system or for increasing the connection capacity of the existing transmission system if after the installation of the connection the user’s electricity consumption will increase by at least 100,000 megawatt hours per year or with a nominal capacity of the connection of at least 50 megawatts. Cabinet Regulation No. 476 “Regulation on Special Connection to the Electricity Transmission System”
Steps to install connections
The processes of the permitted capacity changes shall match connection installation processes.
Prior to the preparation of the application, the User or the Producer must evaluate the place of connection, considering the budgeted capacity in the long term as well as electricity costs, considering the connection tariff (rate). The Users or Producers with a capacity of up to 10MVA mainly choose to install connections to the electricity distribution system, whereas a higher capacity connection can be budgeted for the electricity transmission system.
Prior to the preparation of the application we encourage you to discuss the possible connection solutions. Please email: firstname.lastname@example.org regarding your preferred timing of the meeting with the company's specialists concerning the installation of the connection
- The User’s application for the new electricity system connection or for increasing the permitted capacity of the existing connection
