Free QuoteCapacity mechanisms should account for the capacity value of electricity storage. In electricity markets around the world, the substantial increase of intermittent renewable electricity generation has intensified concerns about generation adequacy, ultimately driving the implementation of capacity remuneration mechanisms.
Barriers exist for electricity storage to participate in some capacity mechanisms. Specification of a capacity mechanism affects technology mix and generation adequacy. Call options with a strike price increase the competitiveness of electricity storage. Low storage capacity credits create a strong bias towards conventional power plants.
The additional capacity remuneration then leads to more storage investments as compared to an EOM. This effect is particularly important in countries with high capacity needs in the medium-term (2030–2040), where storage technologies are still rather expensive to build. 4.4.3.
Specification of a capacity mechanism affects technology mix and generation adequacy. Call options with a strike price increase the competitiveness of electricity storage. Low storage capacity credits create a strong bias towards conventional power plants. Capacity mechanisms should account for the capacity value of electricity storage.
This is an essential aspect as the literature suggests that the nameplate capacity of storage is not identical with the amount of firm capacity that this technology can provide. In contrast, Khan et al. (2018) use the rather basic approach of having the storages bid their full nameplate capacity.
In this setting, the conventional power plant has constant difference costs since it is not affected by the required storage duration. Contrary, the capacity of the small storage unit is already derated under relatively low storage duration requirements due to its limited storage volume.
