ANNEX V Technical provisions relating to combustion plants

PART 2 Emission limit values for combustion plants referred to in Article 30(3)

6. Emission limit values (mg/Nm³) for NO_x and CO for gas fired combustion plants

a For single cycle gas turbines having an efficiency greater than 35 % – determined at ISO base load conditions – the emission limit value for NOx shall be 50xη/35 where η is the gas turbine efficiency at ISO base load conditions expressed as a percentage.
	NOx	CO
Combustion plants other than gas turbines and gas engines	100	100
Gas turbines (including CCGT)	50a	100
Gas engines	75	100

For gas turbines (including CCGT), the NO_x and CO emission limit values set out in this point apply only above 70 % load.

Gas turbines and gas engines for emergency use that operate less than 500 operating hours per year are not covered by the emission limit values set out in this point. The operator of such plants shall record the used operating hours.
