Provided that any refusal to recognise a guarantee of origin as such proof, in particular for reasons relating to the prevention of fraud, shall be based on objective, transparent and non-discriminatory criteria>
Provided further that, where the Authority refuses to recognise a guarantee of origin issued in another Member State, it shall recognise that guarantee of origin where the Commission requires such recognition under Article 5(6) of the Directive.
6. (1) The Authority shall establish an analysis of the national potential for the application of high-efficiency cogeneration, including high-efficiency micro-cogeneration.
(2) The analysis shall>
(a) be based on well-documented scientific data and comply with the criteria listed in Fourth Schedule to these regulations<
(b) 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<
(c) 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.
(3) The Authority shall for the first time not later than 21
January 2007 and thereafter every four years, evaluate progress towards increasing the share of high-efficiency cogeneration.
7. (1) The Authority may promote the use of cogeneration through the implementation of such measures as it may consider expedient and which are not contrary to the provisions of the Act or of these regulations.

(3) The Authority, subject to the Minister’s approval, may facilitate access to the grid system of electricity produced from high- efficiency cogeneration from small scale and micro cogeneration units.
9. (1) The Authority shall evaluate the existing legislative and regulatory framework with regard to authorisation procedures or the other procedures laid down in regulation 12 of the Electricity Regulations, 2004, which are applicable to high-efficiency cogeneration units. Such evaluation shall be made with a view to>
(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 full account of the particularities of the various cogeneration technologies.

SECOND SCHEDULE

Regulations 4(1), 5(4), 10(2), 11(1) and (3), 12(1) and (3) Calculation of electricity from cogeneration

Values used for calculation of electricity from cogeneration shall be determined on the basis of the expected or actual operation of the unit under normal conditions of use. For micro-cogeneration units the calculation may be based on certified values.

(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 the First Schedule to these regulations, with an annual overall efficiency of at least 75%; and

(ii) in cogeneration units of type (a) and (c) referred to in the First Schedule to these regulations with an annual overall efficiency set by the Authority 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 the First Schedule to these regulations) 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 the First Schedule to these regulations) cogeneration is calculated according to the following formula:

ECHP = HCHP . C

where:

“ECHP” is the amount of electricity from cogeneration

“C” is the power to heat ratio

“HCHP” 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 the First Schedule to these regulations

B 26

provided that the calculated cogeneration electricity is less or equal to total electricity production of the unit:

If the Authority introduces default values for power to heat ratios for units of type (f), (g), (h), (i), (j) and (k) referred to in the First Schedule to these regulations, such default values shall be published and shall be notified to the Minister.

(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) of this Schedule.

(d) The Authority 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 the operational data of the specific unit.

(e) The Authority may use other reporting periods than one year for the purpose of the calculations according to paragraphs (a) and (b) of this Schedule.

B 27

THIRD SCHEDULE

Regulations 4(1), 5(4), 10(2), 11(2) and 12(2) Methodology

for determining the efficiency of the cogeneration process

Values used for calculation of efficiency of cogeneration and primary energy savings shall be determined on the basis of the expected or actual operation of the unit under normal conditions of use.

(a) High-efficiency cogeneration

For the purpose of these regulations high-efficiency cogeneration shall fulfil the following criteria:

(i) cogeneration production from cogeneration units shall provide primary energy savings calculated according to paragraph (b) of this Schedule of at least 10% compared with the references for separate production of heat and electricity,

(ii) production from small scale and micro cogeneration units providing primary energy savings may qualify as high- efficiency cogeneration.

(b) Calculation of primary energy savings

The amount of primary energy savings provided by cogeneration production defined in accordance with the Second Schedule to these regulations shall be calculated on the basis of the following formula:

PES = 1 –

1

CHP H

+

Ref H

CHP E

Ref E

× 100%

where:

“PES” is primary energy savings.

B 28

“CHP H ” is the heat efficiency of the cogeneration production defined as annual useful heat output divided by the fuel input used to produce the sum of useful heat output and electricity from cogeneration.

“Ref H ” is the efficiency reference value for separate heat production.

“CHP E ” is the electrical efficiency of the cogeneration production defined as annual electricity from cogeneration divided by the fuel input used to produce the sum of useful heat output and electricity from cogeneration. Where a cogeneration unit generates mechanical energy, the annual electricity from cogeneration may be increased by an additional element representing the amount of electricity which is equivalent to that of mechanical energy. This additional element will not create a right to issue guarantees of origin in accordance with regulation 5 of these regulations.

“Ref E ” is the efficiency reference value for separate electricity production.

(c) Calculations of energy savings using alternative calculation according to sub-regulation (2) of regulation 11 of these regulations

If primary energy savings for a process are calculated in accordance with sub-regulation (2) of regulation 11 of these regulations the primary energy savings shall be calculated using the formula in paragraph (b) of this Schedule replacing:

“CHP H ” with “H ” and

“CHP E ” with “E ”, where:

H shall mean the heat efficiency of the process, defined as the annual heat output divided by the fuel input used to produce the sum of heat output and electricity output.

E shall mean the electricity efficiency of the process, defined as the annual electricity output divided by the fuel input used to produce the sum of heat output and electricity output. Where a cogeneration unit generates mechanical energy, the annual electricity from cogeneration may be increased by an additional element representing the amount of electricity which is equivalent to that of mechanical energy. This additional element will not create a right to issue guarantees of origin in accordance with regulation 5 of the regulations.

B 29

(d) The Authority may use other reporting periods than one year for the purpose of the calculations according to paragraphs (b) and (c) of this Schedule.

(e) For micro-cogeneration units the calculation of primary energy savings may be based on certified data.

(f) Efficiency reference values for separate production of heat and electricity

The principles for defining the efficiency reference values for separate production of heat and electricity referred to in sub- regulation (1) of regulation 5 of these regulations and in the formula set out in paragraph (b) of this Schedule shall establish the operating efficiency of the separate heat and electricity production that cogeneration is intended to substitute.

The efficiency reference values shall be calculated according to the following principles:

(i) For cogeneration units as defined in regulation 4 of these regulations, the comparison with separate electricity production shall be based on the principle that the same fuel categories are compared.

(ii) 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.

(iii) 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.

B 30

FOURTH SCHEDULE Regulation 6(2)

Criteria for analysis of national potentials for high-efficiency cogeneration

(a) The analysis of national potentials referred to in regulation 6 of these regulations shall consider:

(i) 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;

(ii) the type of cogeneration technologies as listed in the First Schedule to these regulations that are likely to be used to realise the national potential;

(iii) the type of separate production of heat and electricity or, where feasible, mechanical energy that high-efficiency cogeneration is likely to substitute; and

(iv) 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.
