  • Investor applies for the connection
  • In application he defines the subject which is submitting the application
  • He attaches the Certificate of Land Ownership
  • Indicates which PTV output he wants to install


  • Based on application respective distribution company issues preliminary opinion
  • It implies information about maximum connectable output, location, exact place of connection and technical conditions of connection


  • Following the issue of preliminary opinion the investor is obliged to obtain all the necessary permissions and opinions of involved institutions
  • After their receipt the investor request the respective distribution company for the conclusion of preliminary contract on connection


  • Documents necessary for the conclusion of preliminary contract on connection
  • Standpoint of the distribution company
  • Admissible reserved capacity of connection
  • Detailed territorial plan

  • Standpoint of authority of water resources protection
  • Categorisation of land, opinion on possibility of constrution
  • Decision of Ministry of Agriculture
  • Written opinion on the detailed territorial plan and preliminary contract with the distribution company


  • Preliminary contract on connection is a binding document fulfilling all legislative conditions necessary for the conclusion of the contract on connection.
  • After its conclusion the investor can apply for the Building permission. However, he must also attach projects for the building permission.


  • After granting the building permission the investor concludes the contract with respective distribution company.


  • After granting the building permission the investor can commence construction works and the final building approval he concludes the contract on purchase of electricity with respective distribution company.


  • Following conditions must be met to connect PVT power station to the network :
  • Connection must be conducted in accordance with Par. 3 3 of Notice Nr. 6 as of 9.6.2004 on connection of producer and consumer of electricity through transfer network IDB Nr. 74 as of 24.08.2004
  • It is imperative to meet the conditions stipulated in the Notice Nr. 14, as of 15.06.2005 on the technical rules and norms, for designing and use of facilities and appliances for the production, transmission and distribution of electric energy.


  • Requirements for the appliances which must be attached to the central:
  • All building components for connecting of the facility (photovolt. Modules, invertors, commutators, etc.) must comply with EU standards and the respective Bulgarian requirements. Before conclusion of the Contract on connection there must be documents for the approval of compliance submitted
  • Invertors must be connected to the three phase system symetric-sinusoid incoming voltage
  • Outgoing voltage from invertor to the network must comply with EU standards EN 50160 as well as norms defined by the Government commission for energy and water regulation. Furthermore, it must comply with qualitative requirements of electric appliances (June 2004) and Chapter VII. of Head VI. of Regulation Nr. 6 as of 9 June 2004 on Connection of producers and consumers of electricy through transmission and distribution network


  • Measurement of electricity
  • Is realised in modules Measurement from GRU of power station with one indirect, static, three-phase energy meter for active and non-active energy with measurements in four quadrants which must have apossibility of storage on factory profile for active and reactive energy for the 15-minute-period during 62 days
  • Energy measurement for production and consumption of all objects and properties must be realised with one measurement


  • Service zones
