Annex No 1 to Decree No 37 / 2016 Coll.
Method of determining total efficiency, quantity of mechanical energy and determination of electricity from cogeneration
1. The total efficiency of the ηcell cogeneration unit shall be determined using the formula:
ηcelk = ESV + EM + QUŽ / QPAL KJ,
where:
Esv is the amount of electricity produced in the cogeneration unit measured at generator terminals [MWh]
EM is the amount of mechanical energy obtained by energy transformation in the cogeneration unit in the cogeneration process, which is not further transformed into electricity [MWh]
QUŽ is the amount of useful heat [MWh]
QPAL KJ is the total fuel [MWh].
2. If a part of the fuel is recovered in chemicals and used, it can be deducted from the total fuel before calculating the total efficiency.
3. The amount of mechanical energy EM shall be determined as the amount of heat energy used to convert into mechanical energy which has not been used to produce electricity or as the amount of mechanical energy that has been passed on to a substance or other device that does not produce electricity.
4. The determined value of mechanical energy EM shall be used only as input for the calculation of the total efficiency of the cogeneration unit or for the determination of the electrical efficiency of the cogeneration used in the calculation of the primary energy savings referred to in point 1 of Annex 2 to this Decree.
5. Where the total efficiency of the cogeneration unit is lower than that provided for in Article 3 (6) and where the cogeneration unit produces electricity that is not linked to useful heat, the total amount of electricity produced in the cogeneration unit shall be divided into the amount of electricity generated from cogeneration and the amount of electricity not derived from cogeneration. In this case, the amount of electricity from cogeneration shall be determined according to the following formula:
EKVET = CZK * CSKUT,
where:
EKVET is the quantity of electricity from cogeneration [MWh]
QUŽ is the amount of useful heat [MWh]
CSKUT is the ratio of electricity to heat [-].
6. Where the total efficiency of the cogeneration unit is lower than the values referred to in Paragraph 3 (6) and all electricity produced is linked to useful heat, the amount of electricity from cogeneration is equal to the terminal generation of electricity from cogeneration unit and there is no distribution of the total amount of electricity produced in cogeneration unit to the amount of electricity produced from cogeneration and to the amount of electricity not produced from cogeneration.
7. Where the calculated value of electricity from the combined electricity and heat generation EKVET is higher than the measured value of the total amount of electricity produced in the cogeneration unit measured at generator terminals, the measured value of the total amount of electricity produced in the cogeneration unit measured at generator terminals shall be used as the quantity of electricity produced from cogeneration.
8. Quantities of electricity produced separately from cogeneration shall not be included in the quantity of electricity produced separately without the supply of useful heat.
9. For example, heat supplied to the thermal energy supply system, heat in the flue gas generated from the cogeneration process used for direct heating or drying needs or heat intended for further use for technological purposes, other than heat recovery for self-consumption of cogeneration units used for further conversion into electrical or mechanical energy, shall be included in the quantity of useful heat QUŽ. The quantity of useful heat shall not include, for example, the quantity of heat supplied directly from boilers or reduction stations without electricity production. The supply of useful heat shall be reduced by the amount of heat contained in the condensate returned from the cogeneration process in the case of steam output.
10. In the case of cogeneration units using a common steam bus, the amount of total fuel shall be distributed between each cogeneration unit in proportion to the amount of steam consumed by each cogeneration unit.
11. The ratio of electricity and heat CSKUT shall be determined on the basis of the actual measured amount of useful heat and electricity linked to the production of useful heat during the period when the cogeneration unit is operating in a fully combined mode with only useful heat, not later than the last day before the first statement is transmitted under the Decree on the reporting and registration of electricity and heat from supported sources and to implement certain other provisions of the Law on Supported Energy Sources to the Market Operator system or immediately after any change that may significantly affect the ratio of electricity and heat. This is a one-off measurement of useful heat and electricity values from which the CSKUT ratio is determined.
12. In the event that, in view of the demand for useful heat or the characteristics of the cogeneration unit, the operation under the full combined mode with the production of electricity linked to useful heat is not possible, the manufacturer shall determine the ratio of electricity to heat CSKUT according to the formula:
CSKUT = Esv1-Esv2 / QUŽ,
where
ESV1 is the quantity of electricity produced in the cogeneration unit measured at generator terminals at operating conditions with the highest in normal operation achievable by the production of the useful heat QUŽ and at the same time at the highest in normal operation attainable fuel consumption [MWh]
ESV2 is the amount of electricity produced in the cogeneration unit measured at generator terminals at operating conditions based on the operating state of the ESV1 measurement, where the useful heat supply is stopped and the fuel supply is reduced in such a way that the production of non-useful heat is identical to that of the ESV1 determination [MWh]
QUŽ is the amount of useful heat [MWh].
13. Measurements shall be carried out for the same period for both operating conditions at outdoor temperature below 15 ° C. If possible, the outdoor temperature is the same for both operating conditions.
14. If the ratio of electricity to heat CSKUT cannot be reliably determined from the measured values obtained in the framework of the one-off measurement referred to in points 11 to 13, the average value of the ratio of electricity to heat CSKUT may be determined by calculating the energy balance established per calendar month on the basis of the actual measured values.
