Wholesale electricity markets use different market designs to handle congestion in the transmission network. We compare nodal, zonal and discriminatory pricing in general networks with transmission constraints and loop flows. We conclude that in large games with many producers who are allowed to...

Transport constraints limit competition and arbitrageurs' possibilities of exploiting price differences between commodities in neighbouring markets. We analyze a transportation network where oligopoly producers compete with supply functions under uncertain demand, as in wholesale electricity...

In multi-unit auctions, such as auctions of commodities and securities, and financial exchanges, it is necessary to specify rationing rules to break ties between multiple marginal bids. The standard approach in the literature and in pratice is to ration marginal bids proportionally. This paper...

In most network asset procurement exercises, network configurations are predefined by the auctioneers. Bidders can neither propose different network configurations nor can they submit bids on a group of network links. We believe the market itself can be designed better. We present a lot...

We demonstrate how suppliers can take strategic speculative positions in derivatives markets to soften competition in the spot market. In our game, suppliers first choose a portfolio of call options and then compete with supply functions. In equilibrium firms sell forward contracts and buy call...

The UK has ambitious plans for exploiting offshore wind for electricity production in order to meet its challenging target under the EU Renewable Energy Directive. This could involve investing up to £20bn in transmission assets to bring electricity ashore. An investment of this magnitude calls...

One of the biggest challenges in the area of infrastructure investment is the provision of funding to finance activities. This paper presents an auction design which can reduce the financing cost of infrastructure investments by allowing the length of the regulatory funding period to be...

We explore the different competitive mechanisms applied by electric utilities from the USA in promoting cost-effective Distribution Generation (DG) resources and the challenges that they face due to the increase in DG connections. Case studies from California, Oregon, Colorado and New York are...

Energy policy aims to deliver security, sustainability and affordability, but politicians treat security of supply as over-riding. Absent market and regulatory failures, liberalized energy-only electricity markets might deliver adequate capacity. Ambitious targets for subsidized renewables and...

The supply function equilibrium provides a game-theoretic model of strategic bidding in oligopolistic wholesale electricity auctions. This paper presents an intuitive account of current understanding and shows how welfare losses depend on the number of firms in the market and their asymmetry....
