The decline of traditional utilities based on dispatchable generation assets can thus degrade the security of electricity supply. Of course, countervailing measures such as capacity mechanisms or long-term support for dispatchable assets, in particular if they are low-carbon such as hydro or nuclear, can internalise any newly arising external effects. This holds, in particular, for baseload producers such as nuclear which rely on high load factors and predictable prices in order to recoup their high fixed costs.
