Nuclear Energy and Renewables: System Effects in Low-carbon Electricity Systems: Method comments to a NEA report
2012 (English)Report (Other (popular science, discussion, etc.))
OECD Nuclear Energy Agency (NEA) released a new report on 29 November 2012. The study recommends that decision-makers should take full electricity system costs into account in energy choices and that such costs should be internalised according to a “generator pays” principle.
The study, entitled Nuclear Energy and Renewables: System Effects in Low-carbon Electricity Systems, addresses the increasingly important interactions of variable renewables and dispatchable energy technologies, such as nuclear power, in terms of their effects on electricity systems.
System effects refer to the costs above plant-level costs to supply electricity at a given load and level of security of supply. The NEA report focuses on “grid-level system costs”, the subset of system costs mediated by the electricity grid, which include a) the costs of extending and reinforcing transport and distribution grids as well as connecting new capacity, and b) the costs of increased short-term balancing and maintaining the long-term adequacy of electricity supply.
In this document we will describe in more details the NEA report concerning System Effects in Low-carbon Electricity Systems. We will also comment on the results.
The final conclusion is that there are several question marks concerning the calculation methods used to calculate the “grid-level systems costs” in the (OECD-NEA, 2012) report.
