In the recent past. deregulation has created new types of economic activity in the gas industry, and has centered categories which had been rather marginal before. An example of the latter kind is the concept of network capacity of which the grid operator shall offer plenty in a flexible way, and without discriminating potential market participants. Mathematically this poses the question of what capacity is and how to compute it. Central objects of study in the present talk are gas flows in the pipes and pressures at the nodes, both under uncertainty of gas withdrawals from the network (loads) at exit (delivery) nodes. Assuming the uncertainty of withdrawals is stochastic with known distributions, an efficient method for calculating probabilities for the feasibility of load coverage is presented. It will be seen that computeralgebraic approaches offer interesting perspectives regarding numerical issues.
