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...

In recent years smart metering of electricity demand has attracted attention around the world. A number of countries and regions have started deploying new metering systems; and many others have set targets for deployment or are undertaking trials. Across the board advances in technology and...

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...

Auctions are playing an increasingly prominent role in the planning and operation of energy markets. Comparing the New Electricity Trading Arrangements to the former electricity Pool in England and Wales requires some analysis of the relative merits of uniform versus discriminatory pricing...

In most wholesale electricity markets generators must submit stepfunction offers of supply to a uniform price auction, and the market is cleared at the price of the most expensive offer needed to meet realised demand. Such markets can most elegantly be modelled as the purestrategy, Nash...

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....

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...

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...

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...

This paper addresses three questions that are relevant to integrating different regional transmission areas. Market integrating normally increases the number of competitors and should therefore reduce prices but the first section shows that prices could rise when the number of generators...
