Can energy storage be a strategic investment under competition?

These market dynamics serve as a motivation for this study to understand strategic investments in energy storage under competition, taking into account storage impact on the market price. Our work uses energy arbitrage as a test case with the intent to explore additional services in the future.

Is energy storage a price-maker?

When it comes to accounting for energy storage as a price-maker, some studies (e.g., , , , ) only consider the operation of the energy storage asset without accounting for the decision and cost of the storage energy- and power-capacity investment itself.

What challenges does the energy storage industry face?

The energy storage industry faces several notable limitations and gaps that hinder its widespread implementation and integration into power systems. Challenges include the necessity for appropriate market design, regulatory frameworks, and incentives to stimulate investment in energy storage solutions.

How does energy storage affect investment?

The influence of energy storage on investment is contingent upon various factors such as the cost of storage technologies, the availability of government incentives, the design of market mechanisms, the share of generation sources, the infrastructure, economic conditions, and the existence of different flexibility options.

What is a storage competition game model?

Storage competition game model Based on the profits and decision sets of the investors, we formulate the storage competition game G among investors to model their strategic interactions. In the game theory, one key concept is the Nash equilibrium.

What are the inputs in a storage competition model?

The inputs are the investors’ storage parameters as well as the market price function that we will characterize in Section 3. The key process is computing the Nash equilibrium, which will be introduced in Section 4. Fig. 2. Framework of the storage competition model. 3. Market price function
