Electricity markets in many OECD countries already allocate capacity payments of one sort or another (not all motivated by the impacts of variable renewables) and several others are considering it. One question that urgently needs to be addressed in the near future is the extent to which the combined impact of the compression effect and capacity markets affects different dispatchable technologies in different ways. The compression effect, for instance, will affect capital-intensive technologies such as nuclear more significantly than less capital-intensive technologies such as gas.
