In certain areas the biogas feed-in in the network is in wintertime only a small percentage and the area of influence is therefore small, too; but it is large in summertime. This fact principally leads to problems in pipeline connection, operation, constant gas quality delivery and fair billing (see below, Operational Aspects). In the future — when the number of plants and/or biogas production will increase — we will expect a considerable higher impact on network operation and surveillance tasks.
