on the minimum efficiency of energy use in electricity and heat generation
The Ministry of Industry and Trade (hereinafter referred to as "the Ministry ') provides, pursuant to Article 14 (5) of Act No. 406 / 2000 Coll., on Energy Management, as amended by Act No. 359 / 2003 Coll., Act No. 694 / 2004 Coll., Act No. 177 / 2006 Coll. and Act No. 574 / 2006 Coll., (hereinafter referred to as" the Act') for the implementation of Article 6 (1) of the Act:
Subject matter
(1) The Decree sets minimum energy efficiency
(a) in the production of heat energy in:
1. boilers,
2. solar collectors,
(b) the supply of heat energy;
(c) in electricity production,
1. steam block,
2. photovoltaic cells,
(d) in cogeneration of electricity and heat in:
1. gas turbine sets,
2. the gas and steam turbine and combustion boiler set (hereinafter referred to as the "gas cycle");
3. Unit with piston engine,
4. the fuel cell; and
(e) other sources of electricity and heat energy.
(2) The specific method of determining the efficiency of the use of energy in installations for the production of electricity and heat energy is set out in Annexes 1 to 16 to this Decree.
Minimum energy efficiency in heat energy production
(1) The minimum efficiency of heat energy production in boilers is the efficiency of heat energy production in boiler ηv in accordance with Annexes 1 and 2 to this Decree and the efficiency of the supply of heat energy from boiler room or heat energy ηd in accordance with Annex 4 to this Decree.
(2) The minimum efficiency of heat energy production in solar collectors is the efficiency of heat energy production ηk as set out in Annex 15 to this Decree. When assessing the minimum efficiency of these devices when they are fitted to central heat supply systems, the procedure laid down in Annex 15 to this Decree shall be followed.
(3) The minimum efficiency of heat energy production in the operation of boilers, depending on the type of fuel fired and the rated boiler output, is given in Annex 2 to this Regulation, in the operation of gas turbine combustion boilers in Annex 3 to this Regulation. The minimum efficiency of the supply of heat energy from the boiler room is given in Annex 5 to this Decree.
(4) If there are several boilers in the boiler room, the minimum efficiency of heat energy production ηv shall apply to each boiler, except for a boiler which, for serious operational reasons, would be used only at short intervals or with significantly reduced power if necessary. This is without prejudice to compliance with the minimum efficiency of the heat energy supply ηd listed in Annex 5 to this Decree.
(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 to this Decree 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 to this Regulation or Annex 3 to this Regulation or the efficiency of the heat energy supply referred to in Annex 5 to this Regulation need not be met, provided that an energy audit shows that it is technically not possible or economically inefficient. 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 energy efficiency in electricity production
(1) The activity of the use of energy in the production of electricity in the steam block shall be the efficiency of electricity generation ηel, as set out in Annex 6 to this Decree.
(2) The minimum efficiency of electricity generation in the operation of the steam block is given in Annex 7 to this Decree.
(3) The minimum efficiency of electricity production as set out in Annex 7 to this Decree does not apply to a steam block with condensing operation which takes steam from a lower pressure distribution and is usually used to regulate the fluctuating collection of steam from an industrial plant.
(4) If there are more than one block in the power plant, the minimum efficiency of electricity production, as set out in Annex 7 to this Decree, applies to the average value of the whole production plant.
(5) The minimum efficiency of electricity generation in photovoltaic power plants (cells), as set out in Annex 14 to this Regulation, does not apply to installations with a power output of less than 30 kW.
(6) When reconstructing an installation for the production of electricity in a steam condensation block, the minimum efficiency of the generation of electricity referred to in Annex 7 to this Regulation need not be met if an energy audit demonstrates that sufficient heat energy or the introduction of cogeneration 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.
(7) Such efficiency shall not apply to the generation of electricity and heat energy in nuclear installations and to the equipment providing only support services, or to the replacement and emergency energy sources used to deal with emergencies to ensure emergency energy supply.
Minimum efficiency of energy use in cogeneration of electricity and heat energy
All cogeneration plants shall comply with the parameters of high efficiency cogeneration set out in Decree No 344 / 2009 Coll., on the details of the method of determining electricity from high efficiency cogeneration based on useful heat demand and on the determination of electricity from secondary energy sources.
Changes in minimum efficiency values
(1) The activities for new and reconstructed energy sources must comply with the European criteria for the best available technology. Amendments to the reference binding values for energy installations selected for the following year may be made no later than 31 March of the year preceding, starting in 2011.
(2) The recalculations of individual designs of efficiency depending on the extent of the reconstruction, the type of replacement or part thereof are set out in the annexes to this decree.
(3) The procedures laid down in Decree No 55 / 1999 Coll., on the method of calculating the amount of damage or damage caused to forests shall not apply to installations which at the same time meet the effectiveness of this Decree and the applicable emission limits under Act No. 86 / 2002 Coll., on air protection and amending certain other laws (Air Protection Act), as amended.
Determination of minimum energy efficiency
(1) The minimum efficiency values are mandatory for project preparation, authorisation procedure, project implementation and permanent operation permit.
(2) If the proposed minimum efficiency cannot be determined by the methods set out in this Decree, the owner of the installation or its operator may proceed in a manner which he submits to the Ministry for decision and approval.
Transitional provisions
(1) This Decree applies to newly established installations for the production of electricity or heat energy and to installations for the production of electricity or heat energy for which a change in finished buildings is carried out (hereinafter referred to as the "reconstruction of the installation ').
(2) This decree does not apply to:
(a) installations for the production of heat energy with a total heat output of up to 400 kW, piston engine units for the total electricity output of the production plant 90 kW and boilers using the heat energy of waste gases from technological processes, even if equipped with heating,
(b) installations for which a building permit has been issued before the entry into force of this Decree pursuant to Act No. 183 / 2006 Coll., on Territorial Planning and Construction Regulations (Construction Act), as amended, and for which a connection agreement or a future connection agreement has been concluded with the relevant TSO or distribution system before the entry into force of this Decree.

Annex No 1 to Decree No. 349 / 2010 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 = Qvx100Qpal = Qvx100MpalxQir (%)
(2) The heat energy produced in the Qv boiler is determined by the type of heat transfer substance
(a) for hot water boilers
Qv = Mvx (ivy-ivs) 1000 (GJ)
(b) for steam boilers producing overheated steam
Qv = Mpx (ip- inv) 1000 (GJ)
(c) for steam boilers producing saturated steam
Qv = Mnvx (ip-inv) 1000 (GJ)
(3) Where the procedure referred to in paragraph 2 is not applicable, because it is not possible to use reliable, technically appropriate measuring instruments or their acquisition to be economically inefficient for boilers with a rated power of up to 2,5 MW or at the total output of a boiler with automatic burners of gaseous or liquid fuel, or where measurements of heat energy production on boilers are not installed, or where measurements are made at the outlet of the boiler, given that the owner is the sole final consumer of heat energy or for other serious reasons, the efficiency of heat energy production shall be determined in using 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 applied to hot water boilers up to 400 kW, provided that they have been shown to meet 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 power-range boilers as referred to in paragraph 3, combustion solid fuels or equipped gas or liquid fuel burners without fully automatic regulation which are not equipped with measurements for the reasons referred to in paragraph 3, the State Energy Inspection may, in justified cases, require that the minimum efficiency of production or the supply of heat 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:
