Article 1 
The harmonised efficiency reference values for separate production of electricity and heat shall be as set out in Annex I and Annex II respectively.
Article 2 

1. Member States shall apply the harmonised efficiency reference values set out in Annex I relating to the year of construction of a cogeneration unit. These harmonised efficiency reference values shall apply for 10 years from the year of construction of a cogeneration unit.
2. From the 11th year following the year of construction of a cogeneration unit, Member States shall apply the harmonised efficiency reference values which by virtue of paragraph 1 apply to a cogeneration unit of 10 years of age. These harmonised efficiency reference values shall apply for one year.
3. For the purpose of this Article the year of construction of a cogeneration unit shall mean the calendar year of the first electricity production.
Article 3 

1. Member States shall apply the correction factors set out in Annex III, point (a) in order to adapt the harmonised efficiency reference values set out in Annex I to the average climatic situation in each Member State.If on the territory of a Member State official meteorological data show differences in the annual ambient temperature of 5 °C or more, that Member State may, subject to notification to the Commission, use several climate zones for the purpose of the first subparagraph using the method set out in Annex III, point (b).
2. Member States shall apply the correction factors set out in Annex IV in order to adapt the harmonised efficiency reference values set out in Annex I to avoided grid losses.
3. Where Member States apply both the correction factors set out in Annex III, point (a) and those set out in Annex IV, they shall apply Annex III, point (a) before applying Annex IV.
Article 4 
If an existing cogeneration unit is retrofitted and the investment cost for the retrofitting exceeds 50 % of the investment cost for a new comparable cogeneration unit, the calendar year of first electricity production of the retrofitted cogeneration unit shall be considered as its year of construction for the purpose of Article 2.
Article 5 
If the cogeneration unit is operated with more than one fuel the harmonised efficiency reference values for separate production shall be applied proportionally to the weighted mean of the energy input of the various fuels.
Article 6 
Decision 2007/74/EC shall be repealed.

ANNEX III
(a) 
Ambient temperature correction is based on the difference between the annual average temperature in a Member State and standard ISO conditions (15 °C).

The correction will be as follows:


((i)) 0,1 %-point efficiency loss for every degree above 15 °C
((ii)) 0,1 %-point efficiency gain for every degree under 15 °C

Example:

When the average annual temperature in a Member State is 10 °C, the reference value of a cogeneration unit in that Member State has to be increased with 0,5 %-points.

(b) 
The borders of each climate zone will be constituted by isotherms (in full degrees Celsius) of the annual average ambient temperature which differ at least 4 °C. The temperature difference between the average annual ambient temperatures applied in adjacent climate zones will be at least 4 °C.

Example:

In a Member State the average annual ambient temperature in place A is 12 °C and in place B it is 6 °C. The difference is more than 5 °C. The Member State has now the option to introduce two climate zones separated by the isotherm of 9 °C, thus constituting one climate zone between the isotherms of 9 °C and 13 °C with an average annual ambient temperature of 11 °C and another climate zone between the isotherms of 5 °C and 9 °C with an average annual ambient temperature of 7 °C.

ANNEX IV

Voltage For electricity exported to the grid For electricity consumed on-site
> 200 kV 1 0,985
100-200 kV 0,985 0,965
50-100 kV 0,965 0,945
0,4-50 kV 0,945 0,925
< 0,4 kV 0,925 0,86Example:
A 100 kWel cogeneration unit with a reciprocating engine driven with natural gas generates electricity of 380 V. Of this electricity 85 % is used for own consumption and 15 % is fed into the grid. The plant was constructed in 1999. The annual ambient temperature is 15 °C (so no climatic correction is necessary).
In accordance with Article 2 of this Decision for cogeneration units older than 10 years of age the reference values of units of 10 years of age should be applied. According to Annex I to this Decision for a natural gas cogeneration unit built in 1999, which has not been retrofitted, the harmonised efficiency reference value applicable in 2011 is the reference value for 2001, 51,7 %. After the grid loss correction the resulting efficiency reference value for the separate production of electricity in this cogeneration unit would be (based on the weighted mean of the factors in this Annex):
Ref Εη = 51,7 % * (0,860 * 85 % + 0,925 * 15 %) = 45,0 %
