The Ministry of Industry and Trade provides pursuant to § 14 (5) of Act No. 406 / 2000 Coll., on Energy Management, ("the Act ') for the implementation of § 6 (1) of the Act:
Subject matter
(1) The Decree determines the minimum efficiency of energy use at:
(a) the production of heat energy in boilers;
(b) the supply of heat energy at the boiler room outlet;
(c) the production of electricity in steam turbines;
(d) combined production of electricity and heat in gas turbine and gas boiler sets;
(e) the combined generation of electricity and heat in the gas and steam turbine and combustion boiler assembly ("the gas cycle");
(f) cogeneration of electricity and heat in a cogeneration unit with piston engine;
(g) the combined production of electricity and heat in the fuel cell.
(2) The decree further determines the method of determining the efficiency of the energy use actually achieved in installations for electricity and heat generation.
Scope
(1) The Decree covers newly established installations for the production of electricity or heat energy and installations for the production of electricity or heat energy for which a change in finished buildings (hereinafter referred to as "installation reconstruction") is being carried out, with the exception of installations for the production of heat energy with a total heat output of up to 200 kW, cogeneration units with piston engines for the total electrical output of the production of 90 kW and boilers using the heat of waste gases from technological processes, even if they are equipped with heating.
(2) The decree covers newly established installations for the production of electricity or heat and the reconstruction of installations for which a building permit has been issued (1) after the date of entry into force of this decree.
Minimum energy efficiency in heat energy production in boilers
(1) The efficiency of heat energy production in boilers shall be the efficiency of heat energy production in boiler ηv in accordance with Annex 1 and the efficiency of heat energy supply from boiler room or heat energy source ηd in accordance with Annex 4.
(2) The minimum efficiency of heat energy production in boiler operation, depending on the type of fuel fired and the rated boiler output, is given in Annex 2, in the gas turbine combustion boiler operation in Annex 3. The minimum efficiency of the supply of heat energy from the boiler room is given in Annex 5.
(3) The minimum efficiency of heat energy production and the minimum efficiency of heat energy supply shall apply both to the separate heat energy source and to the boiler room which is part of the power plant.
(4) If there are several boilers in the boiler room, the minimum efficiency of heat energy generation ηv shall apply to each boiler, except for a boiler which was used only at short intervals or with significantly reduced power in a given year for serious operational reasons. This shall be without prejudice to compliance with the minimum efficiency of the heat energy supply ηd listed in Annex 5.
(5) If measurements of heat energy production and fuel consumption on all boilers are not installed in the boiler room, compliance with the minimum production efficiency for boilers equipped with measurement shall be determined. For other boilers, compliance with the minimum production efficiency shall be determined for the part of the year when the operating conditions allow this, in particular when the boiler was operated separately. Compliance with the minimum efficiency of delivery from the boiler room ηd listed in Annex 5 shall always be ascertained.
(6) When reconstructing the heat energy plant in the boiler, the minimum efficiency of the heat energy production referred to in Annex 2 or Annex 3 or the efficiency of the heat energy supply referred to in Annex 5 need not be met if the energy audit shows that it is technically impossible or economically ineffective. In that case, technical measures and adjustments to the operating regime shall be made to improve the energy efficiency achieved so far. The efficiency value thus determined shall become mandatory for compliance with the operation of the installation.
Minimum efficiency of energy use in the production of electricity in steam turbines
(1) The efficiency of electricity generation shall be as set out in Annex 6.
(2) The minimum efficiency of electricity generation in turboset operation is given in Annex 7.

(5) When reconstructing a power plant in a steam condensing turbojet, the minimum efficiency of electricity production as set out in Annex No 7 need not be met if an energy audit demonstrates that sufficient thermal energy or the introduction of combined heat and power production is technically inappropriate or economically inefficient to meet it. In that case, technical measures and adjustments to the operating regime shall be made to improve the energy efficiency achieved so far. The efficiency value thus determined shall become mandatory for compliance with the operation of the installation.

(3) The peak operation of the set in Annex 13 means the operation of a maximum of 500 hours per year.
(4) Where there are several cogeneration units in the production plant and the production of electricity and heat is measured cumulatively over the whole production plant, the requirement to comply with the minimum efficiency as set out in Annex 13 shall apply to the whole production plant.
(5) The minimum energy efficiency of the combination of cogeneration units and boilers in the production plant is given in Annex 13.

Annex No 1 to Decree No 150 / 2001 Coll.
Determination of heat energy efficiency in boilers
(1) The efficiency of the heat energy production ηv is determined as the ratio of the heat energy produced in the Qv boiler and the energy of the fuel burned in the boiler over the same period of the Qpal (GJ) expressed in%:
ηv = Qv × 100Qpal = Qv × 100Mpal × Qir%
(2) The heat energy produced in the Qv boiler is determined by the type of heat transfer substance
(a) for hot water boilers
Qv = Mv × ivy- ivs1000 GJ
(b) for steam boilers producing overheated steam
Qv = Mp × ip- inv1000 GJ
(c) for steam boilers producing saturated steam
Qv = Mnv × ip- inv1000 GJ
(3) Where the procedure referred to in paragraph 2 is not applicable, because no reliable, technically appropriate measuring instruments or their acquisition would be economically inefficient for boilers with a rated output of up to 2,5 MW or at the total output of a boiler with automatic burners of gaseous or liquid fuel, or where the measurement of heat energy production on boilers is not installed, or where the measurement of the supply at the output of the boiler is not available, given that the owner is the only final consumer of heat energy or for other serious reasons, the efficiency of heat energy production is determined by means of measurements made in the relevant year e.g. by a service technician:
ηv = 100-Zk-4 (%)
(4) The procedure referred to in paragraph 3 may also be used for hot water boilers up to 400 kW, provided that they have been shown to comply with the efficiency requirements of the specific legislation (Government Regulation No 180 / 1999 Coll., laying down technical requirements for the efficiency of hot water boilers burning liquid or gaseous fuels).
(5) In the case of boilers of the power range referred to in paragraph 3, burning solid fuels or equipped with burners on a gaseous or liquid fuel without fully automatic regulation which are not equipped with measurements for the reasons referred to in paragraph 3, the control authority (1) may, in justified cases, require that compliance with the minimum efficiency of the production or supply of heat energy be demonstrated by a heating test.
(6) The efficiency of the production of heat energy in the gas boiler behind the gas turbine ηv shall be determined as the ratio of the difference between the average annual flue gas temperatures at and at the outlet of the boiler and the average annual temperature at the inlet, minus the heat loss from the boiler to the surrounding area:

Determination of energy efficiency in the production plant (boiler room) with cogeneration units
(1) The efficiency of energy production in a production plant comprising one or more cogeneration units and one or more boilers, usually hot water, shall be determined as the ratio of the sum of the physical equivalent of the electrical energy produced measured at the terminals of the generators and the heat energy supplied from the cogeneration units and from the boilers to the total fuel energy burned in cogeneration units and in boilers, expressed in%:
