Projected Costs of Generating Electricity 2005

image of Projected Costs of Generating Electricity 2005

This sixth study in a series on projected costs of generating electricity presents and analyses cost estimates for some 130 power and co-generation (heat and power) plants using coal, gas, nuclear and renewable energy sources. Experts from 19 OECD member countries, 2 international organisations and 3 non-member countries contributed to the study.

The levelised lifetime costs presented and analysed were calculated with input data from participating experts and commonly agreed generic assumptions, using a uniform methodology. Key issues related to generation costs are addressed in the report, including methodologies to incorporate risk in cost assessments, impact of carbon emission trading and integration of wind power into electricity grids.

A reference in the field, this publication will be of interest to energy policy makers, electricity system analysts and energy economists.

Generation costs of Coal-fired, Gas-fired and nuclear power plants

Nuclear Energy Agency

This chapter gives an overview on the costs of electricity generation calculated with generic assumptions for the coal, gas and nuclear power plants considered in the study. It covers investment, operation and maintenance and fuel costs as well as levelised generation cost at 5% and 10% discount rates for a total of 63 plants (27 coal plants, 23 gas plants and 13 nuclear plants). The levelised generation costs were calculated assuming 85% average load factor. For coal and nuclear power plants the economic lifetime was assumed to be 40 years although many countries reported longer expected technical lifetimes.1 For gas-fired plants, most countries reported shorter technical lifetimes, between 20 and 30 years, and in each case economic lifetime was assumed to be equal to technical lifetime. Fossil fuel prices and nuclear fuel...
