After exit day there will be three versions of this legislation to consult for different purposes. The legislation.gov.uk version is the version that applies in the UK. The EU Version currently on EUR-lex is the version that currently applies in the EU i.e you may need this if you operate a business in the EU.
The web archive version is the official version of this legislation item as it stood on exit day before being published to legislation.gov.uk and any subsequent UK changes and effects applied. The web archive also captured associated case law and other language formats from EUR-Lex.
There are outstanding changes not yet made to Commission Decision of 19 November 2008 establishing detailed guidelines for the implementation and application of Annex II to Directive 2004/8/EC of the European Parliament and of the Council (notified under document number C(2008) 7294) (Text with EEA relevance) (2008/952/EC). Any changes that have already been made to the legislation appear in the content and are referenced with annotations.
Revised legislation carried on this site may not be fully up to date. Changes and effects are recorded by our editorial team in lists which can be found in the ‘Changes to Legislation’ area.

THE COMMISSION OF THE EUROPEAN COMMUNITIES,
Having regard to the Treaty establishing the European Community,
Having regard to Directive 2004/8/EC of the European Parliament and of the Council of 11 February 2004 on the promotion of cogeneration based on a useful heat demand in the internal energy market and amending Directive 92/42/EEC(1), and in particular Annex II, point (e) thereof,
Whereas:
(1) Directive 2004/8/EEC provides that Member States must establish a system of guarantees of origin for electricity produced from high-efficiency cogeneration.
(2) This electricity should be generated in a process linked to the production of useful heat and calculated in accordance with the methodology laid down in Annex II to Directive 2004/8/EC.
(3) With an aim of ensuring a harmonised methodology for calculating the amount of electricity from cogeneration, it is necessary to adopt Guidelines clarifying the procedures and definitions laid down in Annex II to Directive 2004/8/EC.
(4) Moreover, those Guidelines should allow Member States to fully transpose crucial parts of Directive 2004/8/EC such as guarantees of origin and establishment of support schemes for high efficiency cogeneration. They should provide further legal certainty for the energy market in the Community and thus contribute to remove barriers for new investments. They should also help to provide clear criteria when screening applications for State aid and financial support for cogeneration from Community funds.
(5) The measures provided for in this Decision are in accordance with opinion of the Committee established by Article 14(1) of Directive 2004/8/EC,
HAS ADOPTED THIS DECISION:
The detailed guidelines clarifying the procedures and definitions necessary for the application of the methodology to determine the quantity of electricity from cogeneration, laid down in Annex II to Directive 2004/8/EC, are set out in the Annex to this Decision.
The guidelines shall establish a harmonised methodology for calculating this amount of electricity.
This Decision is addressed to the Member States.
Done at Brussels, 19 November 2008.

Overall efficiency = (energy output)/(fuel input)
in processes with insufficient useful heat demand or no generation of useful heat energy (for example, gas turbines, internal combustion engines and fuel cells with insufficient or no utilisation of heat);
in processes with heat rejection facilities (for example, in the condensing part of steam cycle power plants and in combined-cycle power plants with extraction-condensing steam turbines).
80 % for ‘Combined cycle gas turbines with heat recovery’ and ‘Steam condensing extraction turbines-based plants’, and
75 % for the other types of cogeneration units,
as indicated in Annex II of the Directive,
The mechanical energy is treated thermodynamically equivalent to electricity with a factor of 1.
Except for micro-cogeneration units, see Step 2 (point 6.2).
Including unavoidable thermal energy losses and ‘non-economically justifiable demanded’ heat produced by the co-generation unit.
Fuel inputs should be measured in equivalent units referred to the main fuel used to produce these fuel inputs.
The power to heat ratio used to calculate the CHP electricity can be used also to calculate the CHP electrical capacity if the unit cannot be operated in a full cogeneration mode, as follows: PCHP = QCHP × C where PCHP is the CHP electrical capacity, QCHP is the CHP heat capacity and C is the power to heat ratio.

This timeline shows the different versions taken from EUR-Lex before exit day and during the implementation period as well as any subsequent versions created after the implementation period as a result of changes made by UK legislation.
The dates for the EU versions are taken from the document dates on EUR-Lex and may not always coincide with when the changes came into force for the document.
For any versions created after the implementation period as a result of changes made by UK legislation the date will coincide with the earliest date on which the change (e.g an insertion, a repeal or a substitution) that was applied came into force.
