The share of biogas on a monthly basis is calculated on the basis of a running average for the last 12 months of production of upgraded biogas that enters the gas system in relation to the last 12 months of Danish gas consumption. The daily figures are calculated on the basis of the last 24 hours of production in relation to the last 24 hours of Danish gas consumption. For daily figures, these are preliminary measurements that have not yet been validated. Therefore, the values may change when the month's numbers are validated.
