The following Excel document provides a list of temperature data for all allocated gas gates. The data was created by NIWA and provides a 30 year average of ground temperature at 30cm depth. The data is presented in degrees Celsius and there is one number per month for each gas gate.
The purpose of this temperature information is for industry participants to use in their data conversion calculations if they wish. The Gas (Downstream Reconciliation) Rules 2008 (the DR rules) require that the data used in the conversion of volume to energy must comply with NZS 5259. Average ground temperature at 30cm depth is provided as an option under NZS 5259.
Currently the use of this information is voluntary however, it is Gas Industry Co’s intent that the DR rules would be changed to incorporate this dataset in the future. If Gas Industry Co were to do this then we would consult with industry on our Statement of Proposal and participants would have the opportunity to submit on whether they think this dataset is appropriate and whether they think it should be mandatory or voluntary to use.
