Convex combinatorial auction of pipeline network capacities


Energy Economics, Available online 31 May 2022

  • Auctioning of natural gas pipeline capacities may be done in a new way.
  • The new method motivates bidding for alternative routes more.
  • Expected allocation costs are lower in the case of the new method.
  • The proposed method enhances infrastructure utilization and fairness.

In this paper we propose a mechanism for the allocation of pipeline capacities, assuming that the participants bidding for capacities do have subjective evaluation of various network routes. The proposed mechanism is based on the concept of bidding for route–quantity pairs. Each participant defines a limited number of routes and places multiple bids, corresponding to various quantities, on each of these routes. The proposed mechanism assigns a convex combination of the submitted bids to each participant, thus its called convex combinatorial auction. The capacity payments in the proposed model are determined according to the Vickrey–Clarke–Groves principle. We compare the efficiency of the proposed algorithm with a simplified model of the method currently used for pipeline capacity allocation in the EU (simultaneous ascending clock auction of pipeline capacities) via simulation, according to various measures, such as resulting and net utility of players, utilization of network capacities, total income of the auctioneer and fairness.
