SCHEDULE 3Greenhouse gas criteria

3

For the purposes of paragraph 2—

a

η h

is the efficiency of the plant in which the heat is generated, calculated as

\frac{H}{F}

where—

i

H is the heat produced by the plant in the form of liquid or steam from all fuels used in that plant; and

ii

F is the energy content of all those fuels;

b

η e l

is the efficiency of the plant in which electricity is generated, calculated as

\frac{A}{F}

where—

i

A is the total amount of electricity generated by the plant from all the fuels used by that plant; and

ii

F is the energy content of all those fuels;

c

C h

is equal to—

i

where the temperature (T) is less than 423 kelvin, 0.3546; and

ii

in any other case,

\frac{T - 273}{T}

, where T is the temperature measured in kelvin of the heat produced by the plant in the form of liquid or steam;

d

E is the greenhouse gas emissions expressed in grammes of CO_{2 eq} per MJ of heat produced, from the production of the biomass, biogas or biomethane and calculated—

i

using the actual value method in the case of participants producing biomethane for injection or using heat for a process in an accredited RHI installation with an installation capacity of 1MWth or above; or

ii

in all other cases, using the actual value method or the default value method.
