Annex No 1 to Decree No 453 / 2012 Coll.
Method of determining total efficiency, quantity of mechanical energy and determination of electricity from cogeneration
1. The overall efficiency of the cogeneration unit or serial assembly of cogeneration units ηcell shall be determined by the formula:
ηcelk = Esv + EM + Qže / QPAL KJ
where:
Esv is the total amount of electricity produced in the cogeneration unit or serial assembly of cogeneration units measured at generator terminals [MWh]
EM is the amount of mechanical energy obtained by the transformation of energy in the steam turbine that is not further transformed into electricity [MWh]
QUŽ is the amount of useful heat [MWh]
QPAL KJ is the total amount of energy consumed for the production of electricity, mechanical energy and useful heat in the cogeneration unit or series of cogeneration units, which is the energy consumption of the fuel determined on the basis of its calorific value and, where applicable, the supplied heat energy from external sources without including heat returned condensate [MWh].
2. Where cogeneration units or cogeneration units and steam condensing turbines use a common steam bus, the total amount of energy in the fuel consumed in the production plant shall be divided between the individual cogeneration units or individual cogeneration units and the individual steam condensing turbines in proportion to the amount of steam consumed by cogeneration units or steam condensing turbines.
3. If a part of the fuel energy entering the cogeneration process is recovered in chemicals and recovered, it may be deducted from the total fuel consumption before calculating the total efficiency.
4. The quantity of mechanical energy EM shall be determined using the formula:
EM = Mp * iVST / 3.6,
where:
EM is the amount of mechanical energy [MWh]
MP is the amount of steam that passed through the turbine or part of the turbine between the inlet and the sampling from the turbine [t]
iVST is a steam enthalpy at turbine inlet [MJ / kg]
ITEMS is an enthalpy of steam at the output of the turbine, possibly from the collection of the turbine [MJ / kg].
5. The determined value of EM shall be used as input to calculate the total efficiency of the cogeneration unit or their serial assembly.
6. In the case of mechanical energy generated simultaneously with the production of useful heat on a steam pressure turbine or on the cogeneration part of a steam condensing demand turbine, this value of mechanical energy shall be used as an input for the calculation referred to in point 1 of Annex 2 to this Regulation.
7. Where the total efficiency of the cogeneration unit or series assembly of cogeneration units is lower than that provided for in Article 2 (3), the total amount of electricity produced in the cogeneration unit or the cogeneration assembly shall be divided into the amount of electricity produced from cogeneration and into the amount of electricity not produced from that production. The quantity of electricity from cogeneration shall be determined according to the following formula:
EKVET = CZK * CSKUT,
where:
EKVET is the amount of electricity from cogeneration [MWh]; If the calculated ECVET value is greater than the total quantity of electricity produced, the total quantity of electricity produced shall be used.
QUŽ is the amount of useful heat [MWh]
CSKUT is the actual ratio of electricity to heat expressing the ratio between the amount of electricity from cogeneration and the amount of useful heat at its highest production in normal operation; In the case of combined renewable electricity and heat generation, useful heat from renewable energy sources [-] shall be used instead of useful heat.
8. The actual ratio of electricity to 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 operates in full combined mode with the supply of only useful heat.
9. In the case where, in view of the demand for useful heat or the characteristics of the cogeneration unit or series assembly of cogeneration units, full combined mode operation with the supply of only useful heat is not possible, the actual ratio of electricity to heat CSKUT shall be determined according to the formula:
CSKUT = Esv1-Esv2 / QUŽ,
where
Esv1 is the quantity of electricity produced in the cogeneration unit or serial assembly of cogeneration units measured at the terminals of generators at operating conditions with the highest in normal operation achievable by the production of useful heat QUŽ and at the same time at the highest in normal operation of the achievable power consumption in fuel [MWh]
Esv2 is the amount of electricity produced in a cogeneration unit or a series of cogeneration units measured at generator terminals at operating conditions based on the operating state of the ESV1 measurement, where the supply of useful heat and input power in the fuel is stopped 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 when determining ESV1 [MWh].
10. Measurements shall be made for the same period for both operating conditions at outdoor temperature up to 10 ° C. If possible, the outdoor temperature is the same for both operating conditions.
11. The actual ratio of electricity to heat CSKUT shall be determined on 1 January 2013 or on the date on which the cogeneration unit or their serial assembly is put into service and at the same time immediately after any modification of the cogeneration unit or their serial assembly which may significantly affect the actual ratio of electricity to heat.
12. For cogeneration units or their series assemblies which are under construction or in the first year of operation and for which the measured data cannot be obtained, the value of the design of the electricity / heat ratio in full combined mode specified by the cogeneration unit manufacturer may be used instead of the CSKUT value.
13. By 31 December 2013, for condensation demand turbines, the electricity / heat ratio determined as follows may be used to calculate the amount of electricity from cogeneration:
ECVET = Qzi · yko · Xp [MWh],
where
EKVET is the amount of electricity from cogeneration [MWh]; If the calculated ECVET value is greater than the total quantity of electricity produced, the total quantity of electricity produced shall be used.
Qzo is the amount of useful heat [MWh]
yko is the guide number whose values are set out in Table 1 of this Annex

Note to Table 1:
1) Wood material with a relative humidity of up to 30% and noble fuels with a predominant proportion of wood matter.
7. For the calculation of primary energy savings, the harmonised efficiency benchmark set out in Table 1 of this Annex shall be used in relation to the year of entry into service of the cogeneration unit. This harmonised efficiency reference value shall apply for a period of 10 years from the year of entry into service of the cogeneration unit. The year of entry into service of the cogeneration unit is the calendar year in which the electricity generation started.
8. From the eleventh year following the entry into service of the cogeneration unit, a harmonised efficiency reference value shall be used for the separate generation of electricity, which shall be used in accordance with point 7 for a cogeneration unit of 10 years of age. This harmonised efficiency benchmark shall apply for a period of one year.
9. Where the cogeneration unit has been technically evaluated (upgraded or reconstructed) and the investment costs of its technical assessment exceed 50% of the investment costs for a new comparable cogeneration unit, the calendar year of the first generation of electricity in the improved cogeneration unit shall be considered for the purpose of point 7 for the year of its entry into service.
10. If only one type of fuel is used for the cogeneration unit, the value of ηripalE from Table 1 of this Annex shall be directly added to the ηrpalE value. In case of co-use of several types of fuels, the resulting harmonised efficiency reference value for separate generation of electricity shall be determined as the weighted average of the individual quantities of energy in the fuel.

11. The harmonised efficiency reference value for the separate generation of electricity is increased by a correction factor for the climate conditions of the latter, which is set at + 0,7% for the Czech Republic.
12. The correction factor for climate conditions shall not apply to cogeneration units based on fuel cells.
13. The harmonised efficiency reference value for separate generation of electricity shall be further adjusted depending on network losses directly related to the voltage level of the cogeneration unit connection using the voltage level correction factor of the knap connection. If the cogeneration unit supplies electricity at one voltage level, the kinap value shall be directly added to the knap value from Table 2 of this Annex.

If the cogeneration unit supplies electricity to multiple voltage levels, the voltage level correction factor shall be evaluated on the basis of the weighted average of the electricity supplied.
knap = knapi = 1nkinap * Ei / knapi = 1nEi -,
where:
Ei are individual shares of the quantity of electricity delivered to different voltage levels [MWh]
kinap are the correction factor values of the voltage level connection [-].
14. The resulting harmonised efficiency reference value for separate generation of electricity for the calculation of primary energy savings in point 1 shall be determined using the formula:
