Deddfwriaeth yn deillio o’r UE
Pan adawodd y DU yr UE, cyhoeddodd legislation.gov.uk ddeddfwriaeth yr UE a gyhoeddwyd gan yr UE hyd at ddiwrnod cwblhau’r cyfnod gweithredu (31 Rhagfyr 2020 11.00 p.m.). Ar legislation.gov.uk, mae'r eitemau hyn o ddeddfwriaeth yn cael eu diweddaru'n gyson ag unrhyw ddiwygiadau a wnaed gan y DU ers hynny.
Mae'r eitem hon o ddeddfwriaeth yn tarddu o'r UE
Mae legislation.gov.uk yn cyhoeddi fersiwn y DU. Mae EUR-Lex yn cyhoeddi fersiwn yr UE. Mae Archif Gwe Ymadael â’r UE yn rhoi cipolwg ar fersiwn EUR-Lex o ddiwrnod cwblhau’r cyfnod gweithredu (31 Rhagfyr 2020 11.00 p.m.).

8.RULES FOR ASSIGNING FUELS AND EMISSIONS OF COMBINED HEAT AND POWER PRODUCTION (CHP) FOR THE PURPOSE OF UPDATING BENCHMARK VALUES
This section applies to situations where an operator, for the purpose of updating benchmark values, has to attribute inputs, outputs and emissions of cogeneration units to sub-installations.
For the purposes of this section, ‘cogeneration’ is used as defined in point (30) of Article 2 of Directive 2012/27/EU of the European Parliament and of the Council(1).
The emissions of a cogeneration unit are determined as
| EmCHP = Σ ADi · NCVi · EFi + EmFGC | (Equation 8) |
Where EmCHP are the annual emissions of the cogeneration unit expressed as t CO2, ADi are the annual activity data (i.e. quantities consumed) of fuels i used for the CHP unit expressed in tonnes or Nm3, NCVi the net calorific values of fuels i expressed as TJ/t or TJ/Nm3, and EFi the emission factors of fuels i expressed in t CO2/TJ. EmFGC are process emissions from flue gas cleaning expressed in t CO2.
The energy input to the CHP unit is calculated in accordance with Equation 6. The respective annual average efficiencies of heat production and electricity (or mechanical energy, if applicable) production are calculated as follows:
| ηheat = Qnet /EIN | (Equation 9) |
| ηel = Eel /EIN | (Equation 10) |
Where ηheat (dimensionless) is the annual average efficiency of heat production, Qnet is the annual net amount of heat produced by the cogeneration unit expressed as TJ as determined in accordance with section 7.2, EIN the energy input as determined using Equation 6 expressed as TJ, ηel (dimensionless) is the annual average efficiency of electricity production, and Eel the net annual electricity production of the cogeneration unit, expressed as TJ.
Where the operator provides evidence to the satisfaction of the competent authority that the determination of the efficiencies ηheat and ηel is technically not feasible or would incur unreasonable costs, values based on technical documentation (design values) of the installation shall be used. If no such values are available, conservative default values of ηheat = 0,55 and ηel = 0,25 should be used.
The attribution factors for heat and electricity from CHP are calculated as
Where FCHP,Heat is the attribution factor for heat and FCHP,El is the attribution factor for electricity (or mechanical energy, if applicable), both expressed without dimension ηref, heat is the reference efficiency for heat production in a stand-alone boiler, and ηref,el the reference efficiency of electricity production without cogeneration. For the reference efficiencies the operator shall apply the appropriate fuel-specific values from the Commission Delegated Regulation (EU) 2015/2402(2) without application of the correction factors for avoided grid losses in Annex IV to that Regulation.
For attributing the energy input or emissions of the cogeneration unit to the production of heat and electricity (or mechanical energy, if applicable), the operator shall multiply the total energy input or emissions with the respective attribution factor for heat or electricity.
The specific emission factor of the CHP-related measurable heat to be used for the attribution of heat-related emissions to sub-installations in accordance with section 10.1.2 is calculated as
| EFCHP,Heat = EmCHP · FCHP,Heat /Qnet | (Equation 13) |
Where EFCHP, heat is the emission factor for the production of measurable heat in the cogeneration unit expressed as t CO2/TJ.

Mae deddfwriaeth ar gael mewn fersiynau gwahanol:
Y Diweddaraf sydd Ar Gael (diwygiedig):Y fersiwn ddiweddaraf sydd ar gael o’r ddeddfwriaeth yn cynnwys newidiadau a wnaed gan ddeddfwriaeth ddilynol ac wedi eu gweithredu gan ein tîm golygyddol. Gellir gweld y newidiadau nad ydym wedi eu gweithredu i’r testun eto yn yr ardal ‘Newidiadau i Ddeddfwriaeth’.
Gwreiddiol (Fel y’i mabwysiadwyd gan yr UE): Mae'r wreiddiol version of the legislation as it stood when it was first adopted in the EU. No changes have been applied to the text.
