What is energy storage capacity compensation

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 energy storage operators make decisions?

Energy storage operators act as followers, making decisions regarding storage capacity and operational strategies based on the tariffs set by the grid. Their decision-making process incorporates historical capacity tariffs, operating costs, expected returns, and market dynamics.

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.

Can a capacity tariff optimization model save the energy storage system cost?

If we do not consider the Stackelberg game mechanism, the capacity tariff of the energy storage plant is calculated as 584.76 CNY/MW according to the traditional method, which shows that the capacity tariff optimization model of the grid energy storage plant proposed in this paper can save the system cost.

How does a capacity tariff work for grid-side energy storage stations?

However, according to the current policy of regulatory pricing, particularly the "Opinions on Further Improving the Price Formation Mechanism for Pumped Storage Energy", the capacity tariff for grid-side energy storage stations essentially functions as an equal annual payment mechanism for initial investment recovery.

How does capacity remuneration affect storage investments?

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.
