  "text": "(1) The “relevant date” in relation to a generator means—\n(a) 1st January 2019, in the case of a Tranche B generator;\n(b) 1st October 2019, in the case of a Tranche A generator with a rated thermal input greater than 5 megawatts which—\n(i) has an emission of nitrogen oxides of equal to or greater than 500mg/Nm3, and\n(ii) operates for more than 50 hours per year;\n(c) 1st January 2025, in the case of a Tranche A generator with a rated thermal input greater than 5 megawatts which—\n(i) has an emission of nitrogen oxides of less than 500mg/Nm3, or\n(ii) operates for less than or equal to 50 hours per year;\n(d) 1st January 2030, in the case of a Tranche A generator with a rated thermal input equal to or less than 5 megawatts.\n(2) The “permitting date”—\n(a) in relation to a specified generator falling within paragraph 2(1)(a), is the relevant date in relation to that specified generator;\n(b) in relation to a specified generator falling within paragraph 2(1)(b) or (c), is the earliest of the relevant dates in relation to the generators comprising that specified generator.\n(3) For the purposes of sub-paragraph (1)—\n“Tranche A generator” means a generator—\n(a)with a rated thermal input equal to or greater than 1 megawatt and less than 50 megawatts—\n(i)which came into operation before 1st December 2016,\n(ii)which is the subject of a capacity agreement arising from the 2014 or 2015 capacity auctions (whether or not the generator came into operation before 1st December 2016), or\n(iii)for which a Feed-in Tariff preliminary accreditation application was received by the Gas and Electricity Markets Authority before 1st December 2016;\n(b)with a rated thermal input of less than 1 megawatt—\n(i)which is the subject of a capacity agreement arising from the 2014, 2015 or 2016 capacity auctions (whether or not the generator came into operation before 1st December 2016),\n(ii)for which a Feed-in Tariff preliminary accreditation application was received by the Gas and Electricity Markets Authority before 1st December 2017; or\n(iii)which is the subject of an agreement to provide balancing services entered into before 31st October 2017,\nprovided that a generator ceases to be a Tranche A generator if it is the subject of a capacity agreement, or an agreement for provision of balancing services, where that agreement is entered into after 31st October 2017 and remains in force after 31st December 2018;\n“Tranche B generator” means any generator which is not a Tranche A generator or an excluded generator (and includes a specified generator which has ceased to be a Tranche A generator).\n(4) For the purposes of sub-paragraph (1), in the case of a generator which is comprised in a specified generator falling within paragraph 2(1)(b) or (c), the generator is deemed to have the total rated thermal input of all the generators comprised in the specified generator.",
