68 ANNEXII Definition of electricity from cogeneration Values used for calculation of electricity fronı cogeneration shall be determined on the basis of the expected or actual operation of the unit under realistic conditions. a) Electricity production from cogeneration shall be considered equal to total annual electricity production ofthe unit. · in cogeneration units oftype b), d), e), f), g), and h) referred to in Annex I, with an annual overall effıciency higher or equal to 75%, and in cogeneration units oftype a) and c) referred to in Annex I with an annual overall effıciency higher or equal to 85%. b) Calculations shall be made in order to separate electricity from cogeneration and electricity not produced in a cogeneration process. in cogeneration units with an annual overall effıciency below 75% (cogeneration units oftype b), d), e), f), g), and lı) referred to in Annex I) or with an annual overall effıciency below 85% (cogeneration units oftype a) and c) referred to in Annex 1) The following formula shall be used: E CHP =Q nct • C where E CHP is the amount of electricity from cogeneration C is the power to heat ratio Q1101 is the net heat production froın a cogeneration process (defuıed as total heat production ıninus any heat produced in separate boilers) lf the actual power to heat ratio ofa cogeneration unit is not known, the following default values ınay be used for units of type a), b), c), d), and e) referred to in Annex I provided that the calculated cogeneration electricity is less or equal to total electricity production ofthe unit: Type ol' tlıe uııit Def'ault pmver to he.ıl rnpal'İI)' rıı!io, C 1 >i, ı r i,· ı h�: ı ı i nı: lııl.lu,ıı i:ıl C,)ıntıiııcd eyde ga� ııırhiııı:: wıtlı hcat ll.9:'ı U.75 n:,·m, \'t'Y Stı::aııı h�L·kıın:s�urc tıırt>mı:: OA:'ı ()J(I Stı::aın ı::,ılllkthİll)! exır:ıı::cion ıurhiııc 0.-t� o.,o (,a� ıurlıin� wiılı hc:ıı rı::rı>ıwy 0.55 0,-10 lntı::rııal ı::ombusuıın cııgiııt' 0.75 (J_(ı(J Subject to prior notifıcation to the Commission, Member States ınay use other default values for power to heat ratios than the ones provided in this Annex.
