6 Frequently Asked Questions about “The latest capacity compensation standards for energy storage power stations in the capital”
Should capacity remuneration mechanisms account for the value of electricity storage?
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.
How do utility companies bid for power plant and storage capacity?
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.
How does a capacity mechanism affect electricity storage?
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.
How does a capacity mechanism affect power generation adequacy?
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.
Why do firm capacity auctions have a higher number of nameplate capacity?
Since the total amount of firm capacity to be procured in the capacity auctions is typically predefined, stronger derating of storage technologies leads to a lower capacity contribution of these units and therefore a higher amount of nameplate capacity to be contracted in order to fulfill the desired firm capacity target.
What if a storage operator fails to deliver a contract capacity?
Consequently, storage operators need to fully manage the risk of their offers themselves and are subject to penalties if they fail to deliver their contracted capacity. Due to the energy-limited nature of electricity storage, this is a very rigorous requirement, basically excluding storages from participation in the CRM.
