La série Responsabilité & Environnement publie trimestriellement des dossiers thématiques sur des sujets concernant les risques, le développement durable ainsi que l’énergie et les matières premières. Piloté par un spécialiste du secteur sous l’égide du Comité de rédaction de la série, chaque dossier présente une large gamme de points de vue complémentaires, en faisant appel à des auteurs issus à la fois de l’enseignement et de la recherche, de l’entreprise, de l’administration ainsi que du monde politique et associatif.

The Competitiveness of Nuclear Energy: From LCOE to System Costs

By Jan Horst KEPPLER
Senior Economist
Division of Nuclear Technology Development and Economics, OECD Nuclear Energy Agency
and
Marco COMETTO
Nuclear Energy Analyst
Division of Nuclear Technology Development and Economics, OECD Nuclear Energy Agency

 

Economists used to compare the costs of electricity based on the discounted average lifetime costs of power plants, a metric known as the levelised costs of electricity (LCOE). This transparent and compa­ratively simple metric worked well in a context of regulated markets. Nuclear, coal, gas and hydro thus competed based on their respective capital, labour and fuel costs at the level of the individual plant. Three forces compel a move away from LCOE. First, the social costs of CO2 and local pollutants are becoming an important decision criterion. Second, the liberalisation of electricity markets introduces price and market risk as a dimension of investor cost. Third, the rise of variable renewable energies (VRE) such as wind and solar PV requires new costs metrics, as the system needs to back up variable resources with added capa­city of dispatchable plants. A study by the OECD Nuclear Energy Agency (NEA) shows that integrating sys­tem effects increases the costs of a MWh produced by VREs up to USD 50 when they have a 75% share. While precise amounts vary with penetration and flexibility resources, policymakers need to understand that the presence of VRE requires a new notion of competitiveness that includes system effects.
