This paper uses a market equilibrium model to calculate how the mix of generating capacity would change if large amounts of intermittent renewables are built in Great Britain, and what this means for operating patterns and the distribution of prices over time. If generators bid their marginal...

This paper presents an overview of the main issues associated with the economics of offshore wind. Investment in offshore wind systems has been growing rapidly throughout Europe, and the technology will be essential in meeting EU targets for renewable energy in 2020. Offshore wind suffers from...

On windy days, Denmark tends to export electricity to its neighbours, and to import power on calm days. Storing electricity in this way thus allows the country to deal with the intermittency of wind generation. We show that this kind of behaviour is theoretically optimal when a region with wind...

This chapter discusses the implications of an increasing proportion of renewable energy for the way in which energy companies are regulated. While the scope of regulation varies from country to country, depending on the degree of liberalisation, an increase in the overall cost of energy, and a...

This paper evaluates the impact of intermittent wind generation on hourly equilibrium prices and output, using data on expected wind generation capacity and demand for 2020. Hourly wind data for the period 1994-2005 are used to obtain wind output generation profiles for thirty regions (onshore...

In an attempt to reduce high electricity prices in England and Wales, the government and regulator forced the largest generators to divest some plant in the late 1990s, and introduced New Electricity Trading Arrangements in March 2001. We use a supply function model to simulate prices from April...

The energy utilities – gas and electricity companies – were traditionally regulated monopolies, but once the EU decided to liberalise them, competition policy became applicable. The EU has used a series of Directives to set out the framework for a market-led energy sector, with third party...

Volatile fuel prices affect both the cost and price of electricity in a liberalised market. Generators with the price-setting technology will face less risk to their profit margins than those with a technology that is not price-setting, even if its costs are not volatile. Emissions permit prices...
