Natural Gas is a major source of electricity generation, which is transported in gas form through pipelines over large distances. Recent regulation in the European Union lead to a decoupling of trade, storage and transportation of gas. Transmission System Operators face new challenges originating from the increased flexibility of the entry-exit model of capacity contracts. We present decision support systems that were developed in a research cooperation between several mathematical research institutes in Germany and Open Grid Europe, the largest TSO in Germany. The major task is the verification of booked capacities, which involves finding feasible network configurations for thousands of predicted demand scenarios or proving infeasibility. Topology Expansion and Capacity Maximation problems will also be covered briefly. For all of these long-term planning problems, stationary models of gas flow are used. Finally we discuss ongoing work with OGE, which is focused on two tasks: A day-ahead decision support tool for a newly introduced capacity product for gas-fired power plant; and a tool for the dispatching, both using current network state and transient flow models.
