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 member countries, 2 international organisations and 3 non-OECD countries contributed to the study.

Levelised lifetime costs were calculated with input data from participating experts and commonly agreed generic assumptions, using a uniform methodology. The study shows that the competitiveness of alternative generation sources and technologies depends on many factors and that there is no absolute winner. 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. The projected costs presented are generic and do not reflect the full range of factors (e.g., security of supply, risks and carbon emissions) that investors and other decision makers need to take into account. This report will be, however, a reference for energy policy makers, electricity system analysts and energy economists.
