be based on well-documented scientific data and comply with the criteria listed in Annex IV, identify all potential for useful heating and cooling demands, suitable for application of high-efficiency cogeneration, as well as the availability of fuels and other energy resources to be utilised in cogeneration, include a separate analysis of barriers, which may prevent the realisation of the national potential for high-efficiency cogeneration. In particular, this analysis shall consider barriers relating to the prices and costs of and access to fuels, barriers in relation to grid system issues, barriers in relation to administrative procedures, and barriers relating to the lack of internalisation of the external costs in energy prices.
(a) encouraging the design of cogeneration units to match economically justifiable demands for useful heat output and avoiding production of more heat than useful heat; (b) reducing the regulatory and non-regulatory barriers to an increase in cogeneration; (c) streamlining and expediting procedures at the appropriate administrative level; and (d) ensuring that the rules are objective, transparent and non-discriminatory, and take fully into account the particularities of the various cogeneration technologies.
(a) coordination between the different administrative bodies as regards deadlines, reception and treatment of applications for authorisations; (b) the drawing up of possible guidelines for the activities referred to in paragraph 1, and the feasibility of a fast-track planning procedure for cogeneration producers; and (c) the designation of authorities to act as mediators in disputes between authorities responsible for issuing authorisations and applicants for authorisations.
(a) consider progress towards realising national potentials for high-efficiency cogeneration referred to in Article 6; (b) assess the extent to which rules and procedures defining the framework conditions for cogeneration in the internal energy market are set on the basis of objective, transparent and non-discriminatory criteria taking due account of the benefits of cogeneration; (c) examine the experiences gained with the application and coexistence of different support mechanisms for cogeneration; (d) review efficiency reference values for separate production on the basis of the current technologies.

(a) Electricity production from cogeneration shall be considered equal to total annual electricity production of the unit measured at the outlet of the main generators; (i) in cogeneration units of type (b), (d), (e), (f), (g) and (h) referred to in Annex I, with an annual overall efficiency set by Member States at a level of at least 75 %, and (ii) in cogeneration units of type (a) and (c) referred to in Annex I with an annual overall efficiency set by Member States at a level of at least 80 %.
(b) In cogeneration units with an annual overall efficiency below the value referred to in paragraph (a)(i) (cogeneration units of type (b), (d), (e), (f), (g), and (h) referred to in Annex I) or with an annual overall efficiency below the value referred to in paragraph (a)(ii) (cogeneration units of type (a) and (c) referred to in Annex I) cogeneration is calculated according to the following formula: E CHP = HCHP . C
where: E CHP is the amount of electricity from cogeneration C is the power to heat ratio H CHP is the amount of useful heat from cogeneration (calculated for this purpose as total heat production minus any heat produced in separate boilers or by live steam extraction from the steam generator before the turbine). The calculation of electricity from cogeneration must be based on the actual power to heat ratio. If the actual power to heat ratio of a cogeneration unit is not known, the following default values may be used, notably for statistical purposes, for units of type (a), (b), (c), (d), and (e) referred to in Annex I provided that the calculated cogeneration electricity is less or equal to total electricity production of the unit: Type of the unit Default power to heat ratio, C Combined cycle gas turbine with heat recovery 0,95 Steam backpressure turbine 0,45 Steam condensing extraction turbine 0,45 Gas turbine with heat recovery 0,55 Internal combustion engine 0,75 If Member States introduce default values for power to heat ratios for units of type (f), (g), (h), (i), (j) and (k) referred to in Annex I, such default values shall be published and shall be notified to the Commission. (c) If a share of the energy content of the fuel input to the cogeneration process is recovered in chemicals and recycled this share can be subtracted from the fuel input before calculating the overall efficiency used in paragraphs (a) and (b). (d) Member States may determine the power to heat ratio as the ratio between electricity and useful heat when operating in cogeneration mode at a lower capacity using operational data of the specific unit. (e) The Commission shall establish detailed guidelines for the implementation and application of Annex II, including the determination of the power to heat ratio. Those measures, designed to amend non-essential elements of this Directive by supplementing it, shall be adopted in accordance with the regulatory procedure with scrutiny referred to in Article 14(2).

Each cogeneration unit shall be compared with the best available and economically justifiable technology for separate production of heat and electricity on the market in the year of construction of the cogeneration unit. 3. The efficiency reference values for cogeneration units older than 10 years of age shall be fixed on the reference values of units of 10 years of age. 4. The efficiency reference values for separate electricity production and heat production shall reflect the climatic differences between Member States.
(a) The analysis of national potentials referred to in Article 6 shall consider: the type of fuels that are likely to be used to realise the cogeneration potentials, including specific considerations on the potential for increasing the use of renewable energy sources in the national heat markets via cogeneration, the type of cogeneration technologies as listed in Annex I that are likely to be used to realise the national potential, the type of separate production of heat and electricity or, where feasible, mechanical energy that high-efficiency cogeneration is likely to substitute, a division of the potential into modernisation of existing capacity and construction of new capacity.
(b) The analysis shall include appropriate mechanisms to assess the cost effectiveness — in terms of primary energy savings — of increasing the share of high-efficiency cogeneration in the national energy mix. The analysis of cost effectiveness shall also take into account national commitments accepted in the context of the climate change commitments accepted by the Community pursuant to the Kyoto Protocol to the United Nations Framework Convention on Climate Change. (c) The analysis of the national cogeneration potential shall specify the potentials in relation to the timeframes 2010, 2015 and 2020 and include, where feasible, appropriate cost estimates for each of the timeframes.
