Calorific Value. The calorific value of the gas offtaken at Xxxx’x Xxxx shall be determined in accordance with the Uniform Network Code.
Calorific Value. (1) The calorific value of the gas offtaken at the Premises Supply Meter Point and any Fuel Gas offtaken and any Auxiliary Gas offtaken shall be determined by the Process Gas Chromatograph, specified in Annex B. Installed to BS ISO 15971 and National Grid Gas’s T/SP/ME/1, with Calorific Value determined to ISO 6976 and shall have a sample system compliant with ISO 10715.
(2) The Operator shall give National Grid Gas and the Relevant Shipper reasonable advance notice of the final commissioning of the Process Gas Chromatograph which should include a Performance Evaluation to ISO 10723 carried on the Gas Chromatograph at its final installed location to demonstrate that the instrument is within the required bias and uncertainty [0.14MJ] for the determination of the calorific value.
(3) The Operator shall operate and maintain the Process Gas Chromatograph to National Grid Gas’s T/PM/GQ/3 and T/SP/ME/1 and to BS 15971 and shall, following replacement and or repair of certain key components, as agreed between the parties, carry out a performance evaluation to ISO 10723, at the installed location, to demonstrate that the instrument is within the required bias and uncertainty [0.14MJ] for the determination o the calorific value.]
Calorific Value. 8.1. The calorific value of the gas offtaken at the Supply Meter Point and any Fuel Gas offtaken and any Auxiliary Gas offtaken shall be determined by the Process Gas Chromatograph, specified in Schedule 2 installed to National Gas’s T/SP/ME/1, with Calorific Value determined to ISO 6976 and shall have a sample system compliant with ISO 10715.
Calorific Value. The Calorific Value of the gas offtaken from the System at CSPX and CSPY shall be determined by the NGG Equipment, and the Calorific Value of the gas offtaken from the System at CSPZ shall be determined by the GNI (UK) Equipment.
Calorific Value. The Calorific Value of the gas offtaken from or delivered to the National Grid Gas System at the Interconnection Point shall be determined by the Gas Analysis Equipment.
Calorific Value. Background Respondents’ Views Transco’s View Ofgem’s View
Calorific Value. The generic SCA states, in the Gas Entry Conditions, that the calorific value (CV) of gas entering Transco’s system shall be within 0.5 MJ/m 3 of a target CV provided by Transco. Transco envisages that CV will be in the range 36.9 to 42.3 MJ/m 3. One connecting party has requested that Transco clarify whether the target CV is a normal level for all storage facilities or whether the CV might be altered on a daily basis. This company was concerned that the CV could be altered at Transco’s discretion and that additional administrative costs would fall on the storage operator. It noted that Transco was making no corresponding commitment as to the CV of gas arriving at the storage connection point. Consequently, the company has said that it would prefer to see a fixed CV specified. Transco has said that CV was likely to be a material issue if a storage facility was producing native gas. Transco also stated that withdrawing stored gas could have an impact on flow weighted average CV as the CV of shippers' gas in the system might vary on a seasonal basis. In any event, Transco has said that storage operators will be able to return gas that is outside the CV specification if it was “off-spec” when originally offtaken from Transco’s system. This would, of course, be subject to the Gas Safety (Management) Regulations and a facility’s ability to change the quality of gas.
Calorific Value a) The price of the coal, as determined pursuant to article 7.1.1. through 7.1.9 shall be adjusted by adding thereto a
Calorific Value. 3.3.1 A reference in the Code to “calorific value” or to the “relevant calorific value” of gas delivered to or offtaken from a System shall be a reference:
(a) in the context of a System Entry Point, to the calorific value of gas delivered to the Total System established in accordance with the relevant provisions (if any) of the Network Entry Provisions;
(b) in the context of any System Exit Point or Inter-System Offtake where the quantity of gas conveyed to such point is required to be calculated in accordance with the Gas (Calculation of Thermal Energy) Regulations 1996, to the calorific value established by the Transporter pursuant to those Regulations;
(c) in the context of any other System Exit Point or Inter-System Offtake:
(i) in the case of a NExA Supply Meter Point or Connected System Exit Point, to the calorific value established in accordance with the relevant Network Exit Provisions (if any);
(ii) except as provided in paragraph (i), where there is calorimetric equipment installed (by or with the approval of the Transporter) at the relevant System Exit Point or Inter-System Offtake, to the calorific value ascertained by means of such equipment;
(iii) except as provided in paragraphs (i) and (ii), to the flow weighted average calorific value established as the average of the average calorific values (applicable to the area in which such System Exit Point or Inter- System Offtake is located) referred to in Part II of the above Regulations, weighted by reference to the gas flows each Day at points on the relevant System where apparatus referred to in that Part is located.
3.3.2 Any reference to a quantity of gas delivered or to be delivered to, or offtaken or to be offtaken from, the Total System at a System Entry Point or (as the case may be) System Exit Point shall be construed in accordance with paragraph 3.3.1 above.
3.3.3 For the purposes of the Code, “CV shrinkage” is gas which is unaccounted for as offtaken from the Total System at System Exit Points by reason of the quantities of gas delivered to the Total System exceeding (by virtue of paragraphs 3.3.1 and 3.3.2 above) those offtaken from the Total System.
