Connection to the grid
Updated: 26.09.2017
Heat suppliers are obliged to connect all RES heating devices of independent heat producers that were installed to replace plants fired by fossil fuels. The independent heat producer has to ensure that the heat supplied is consistent with the environmental and quality requirements as well as standards for the security of supply. RES heating devices are connected to the heat transmission network at the technically suitable point which is closest to the heating device to be connected, unless there is a more technically and economically suitable connection point. The connection point is selected by the heat supplier upon the request of an independent heat producer (Chapter IV Art. 24 Law on Energy from Renewable Sources). The connection costs are covered by the independent heat producer (Chapter VI Item 23 Resolution No. O3-74/2013).
Procedure
| Process flow | Connection request. The independent heat producer intending to produce renewable heat shall submit a written connection request to the heat supplier (Chapter VII Item 30 Resolution No. O3-74/2013). Information on technical possibilities and requirements. No later than within 15 calendar days from the receipt of application the heat supplier shall provide the applicant with the detailed information on the technical possibilities and requirements for the connection of the RES-H installation to the heat transmission network (e.g. bandwidth of the grid, technical parameters, etc.). The information shall be provided free of charge (Chapter VII Item 30 Resolution No. O3-74/2013). Connection conditions. Conditions for the connection to the heat transmission network shall be drafted and published by the heat transmission network operator (Chapter VII Item 31 Resolution No. O3-74/2013). Preliminary purchase and sale agreement. The heat supplier and the potential independent heat producer shall conclude a preliminary agreement on purchase and sale of heat. The preliminary agreement contains key conditions, including obligations and responsibility of both parties, date of connection, the way of price setting, etc. The heat supplier can include no independent heat producer discriminating conditions (Chapter VII Item 32, 33 Resolution No. O3-74/2013). Purchase and sale agreement. When entering into the agreement, the independent heat producer shall submit to the heat supplier the findings of the State Energy Inspectorate, stating that the renewable heat producing device complies with the applicable technical and operational requirements (Chapter II Item 8 Resolution No. O3-74/2013). The request of an independent heat producer to connect his installation to the heat transmission network may only be refused if:

| Deadlines | Connection date is provided in the preliminary and final agreements for the connection to the heat transmission network concluded between the heat supplier and the independent heat producer (Chapter VI Item 32 Resolution No. O3-74/2013). |
| Obligation to inform | The heat supplier is obliged to publish monthly forecasts on the monthly heat demand, the quantities of heat which are planned to be purchased and produced as well as fuel structure for the upcoming 12 months (Chapter VII Item 29 Resolution No. O3-74/2013). Within 15 days from the receipt of a written request of an independent heat producer, the heat supplier has to submit detailed information about the technical possibilities and conditions for the connection to the heat transmission network. This includes information on the network bandwidth and other technical parameters such as pressure, temperature and flow. This information must be provided free of charge (Chapter VII Item 30 Resolution No. O3-74/2013). |
