# The Renewables Obligation Order (Northern Ireland) 2009, Article 24: Renewable output of a qualifying combined heat and power generating station

Extent: N.I.

(1) For the purposes of determining the renewable output of a qualifying combined heat and power generating station in any month during which it generates electricity from waste (other than waste which constitutes biomass or is used for permitted ancillary purposes or is an advanced fuel , or is in the form of a liquid or gaseous fuel produced by means of... anaerobic digestion), Article 23 applies subject to the following modifications.
(2) For paragraph (2)(a)(ii) of Article 23 substitute—
“(ii) D is the energy content of all of the renewable sources used in generating that station’s gross output during that month, less the energy content of—
(aa) any fossil fuel from which those renewable sources are in part composed (other than fossil fuel from which a fuel the energy content of which is deducted by virtue of sub-paragraph (cc) is in part composed);
(bb) . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .
(cc) except in the case of an excepted generating station, any of those renewable sources which is a gaseous fuel produced by means of gasification or pyrolysis and which has a gross calorific value when measured at 25 degrees Celsius and 0.1 megapascals at the inlet to the station of less than 2 megajoules per metre cubed,
multiplied by the proportion which the qualifying power output of that station bears to its total power;”.
(3) For paragraphs (5)(a) and (5)(b) of that Article, substitute—
“(a) F is the energy content of the renewable sources used when generating electricity in that way during that month less the energy content of—
(i) any fossil fuel from which those renewable sources are in part composed (other than fossil fuel from which a fuel the energy content of which is deducted by virtue of paragraph (ii) is in part composed);
(ii) except in the case of an excepted generating station, any of those renewable sources which is a gaseous fuel produced by means of gasification or pyrolysis and which has a gross calorific value when measured at 25 degrees Celsius and 0.1 megapascals at the inlet to the station of less than 2 megajoules per metre cubed;
(b) G is the energy content of all of the renewable sources used in generating the station’s gross output during that month less the energy content of—
(i) any fossil fuel from which those renewable sources are in part composed (other than fossil fuel from which a fuel the energy content of which is deducted by virtue of paragraph (ii) is in part composed);
(ii) except in the case of an excepted generating station, any of those renewable sources which is a gaseous fuel produced by means of gasification or pyrolysis and which has a gross calorific value when measured at 25 degrees Celsius and 0.1 megapascals at the inlet to the station of less than 2 megajoules per metre cubed;”.
(4) . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .
