7.RULES FOR DETERMINING NET MEASURABLE HEATU.K.

7.1. Principles U.K.

All specified amounts of measurable heat shall always refer to net amount of measurable heat, determined as the heat content (enthalpy) of the heat flow transmitted to the heat consuming process or external user minus the heat content of the return flow.

Heat consuming processes necessary for operating the heat production and distribution, such as deaerators, make-up water preparation, and regular blow offs, shall be taken into account in the efficiency of the heat system and can therefore not be considered heat consuming processes eligible for allocation.

Where the same heat medium is used by several consecutive processes and its heat is consumed starting from different temperature levels, the quantity of heat consumed by each heat consuming process shall be determined separately, unless the processes fall within the same sub-installation. Re-heating of the transfer medium between consecutive heat consuming processes should be treated like additional heat production.

Where heat is used to provide cooling via an absorption cooling process, that cooling process shall be considered as the heat consuming process.

7.2. Methodologies for determining net amounts of measurable heat U.K.

For the purpose of selecting data sources for quantification of energy flows in accordance with section 4.5, following methodologies for determining net amounts of measurable heat shall be considered:

Method 1: Using measurementsU.K.

Under this method, the operator measures all relevant parameters, in particular temperature, pressure, state of the transmitted as well as the returned heat medium. The state of the medium in case of steam shall refer to its saturation or degree of superheating. The operator furthermore measures the (volumetric) flow rate of the heat transfer medium. Based on the measured values, the operator determines the enthalpy and the specific volume of the heat transfer medium using suitable steam tables or engineering software.

The mass flow rate of the medium is calculated as

(Equation 3)

Where ṁ is the mass flow rate in kg/s, V is the volumetric flow rate in m3/s and υ is the specific volume in m3/kg.

As the mass flow rate is considered the same for transmitted and returned medium, the heat flow rate is calculated using the difference in enthalpy between the transmitted flow and the return, as follows:

= (hflow hreturn ) · (Equation 4)

Where Q is the heat flow rate in kJ/s, hflow is the enthalpy of the transmitted flow in kJ/kg, hreturn is the enthalpy of the return flow in kJ/kg, and ṁ is the mass flow rate in kg/s.

In case of steam or hot water used as heat transfer medium, where the condensate is not returned, or where it is not feasible to estimate the enthalpy of the returned condensate, the operator shall determine hreturn based on a temperate of 90 °C.

If the mass flow rates are known to be not identical, the following shall apply:

  • Where the operator provides evidence to the satisfaction of the competent authority that condensate remains in the product (e.g. in ‘life steam injection’ processes), the respective amount of condensate enthalpy is not deducted;

  • Where heat transfer medium is known to be lost (e.g. due to leakages or sewering), an estimate for the respective mass flow shall be deducted from the mass flow of the transmitted heat transfer medium.

For determining the annual net heat flow from the above data, the operator shall – subject to the measurement equipment and data processing available, use one of the following methods:

  • Determine annual average values for the parameters determining the annual average enthalpy of the transmitted and returned heat medium, and multiply with the total annual mass flow, using equation 4;

  • Determine hourly values of the heat flow and sum up those values over the annual total operating time of the heat system. Subject to the data processing system, hourly values may be substituted by other time intervals as appropriate.

Method 2: Using documentationU.K.

The operator determines net amounts of measurable heat based on documents in accordance with section 4.6 of this Annex, provided that heat quantities provided in such documents are based on metering, or on reasonable estimation methods in accordance with section 3.4 of this Annex.

Method 3: Calculation of a proxy based on measured efficiencyU.K.

The operator determines amounts of net measurable heat based on the fuel input and the measured efficiency related to the heat production:

Q = ηH · EIN (Equation 5)
EIN = Σ ADi · NCVi (Equation 6)

Where Q is the amount of heat expressed in TJ, ηH is the measured efficiency of heat production, EIN is the energy input from fuels, ADi are the annual activity data (i.e. quantities consumed) of fuels i, and NCVi the net calorific values of fuels i.

The value of ηH is either measured by the operator over a reasonably long period, which sufficiently takes into account different load states of the installation or taken from the manufacturer's documentation. In that regard the specific part load curve is to be taken into account by using an annual load factor:

LF = EIN /EMax (Equation 7)

Where LF is the load factor, EIN the energy input as determined using Equation 6 over the calendar year, and EMax  the maximum fuel input if the heat producing unit had been running at 100 % nominal load for the full calendar year.

The efficiency should be based on a situation in which all condensate is returned. A temperature of 90 °C should be assumed for the returned condensate.

Method 4: Calculating a proxy based on the reference efficiencyU.K.

This method is identical to method 3, but using a reference efficiency of 70 % (ηRef,H = 0,7) in Equation 5.

7.3. Distinguishing district heating, EU ETS and non-ETS heat U.K.

Where an installation imports measurable heat, the operator shall determine separately the quantity of heat coming from installations covered by the EU ETS, and heat imported from non-EU ETS entities. Where an installation consumes measurable heat exported from a nitric acid product benchmark sub-installation, the operator shall determine that amount of heat consumed separately from other measurable heat.

Where an installation exports measurable heat, the operator shall determine separately the quantity of heat exported to installations covered by the EU ETS, and heat exported to non-EU ETS entities. Furthermore, the operator shall determine separately quantities of heat qualifying as district heating.

Timeline of Changes

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.
