ANNEX III Correction factors relating to the average climatic situation and method for establishing climate zones for the application of the harmonised efficiency reference values for separate production of electricity (referred to in Article 3(1))

(a) Correction factors relating to the average climatic situation

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) Method for establishing climate zones

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 Correction factors for avoided grid losses for the application of the harmonised efficiency reference values for separate production of electricity (referred to in Article 3(2))

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	0,86

Example:

A 100 kW_el 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 %
