However, the core challenge lies in the lack of an effective cost recovery mechanism, which hampers its economic viability. To address this issue, this paper proposes a capacity compensation mechanism that
Capacity 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.
Next, the different utility companies provide capacity bids consisting of volume and price. While existing capacity is offered at zero cost, 17 the bids for potential new power plant and storage capacity are based on the respective difference costs. These are directly related to the regular investment planning procedure.
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.
If call options with a strike price are implemented, storage units gain a competitive advantage over conventional power plants in the capacity auctions. The additional capacity remuneration then leads to more storage investments as compared to an EOM.
