Profit model of Castries Energy Storage Power Station

Is energy storage a profitable business model?

Although academic analysis finds that business models for energy storage are largely unprofitable, annual deployment of storage capacity is globally on the rise (IEA, 2020). One reason may be generous subsidy support and non-financial drivers like a first-mover advantage (Wood Mackenzie, 2019).

How can energy storage be profitable?

Where a profitable application of energy storage requires saving of costs or deferral of investments, direct mechanisms, such as subsidies and rebates, will be effective. For applications dependent on price arbitrage, the existence and access to variable market prices are essential.

What is a power storage facility?

In the first three applications (i.e., provide frequency containment, short-/long-term frequency restoration, and voltage control), a storage facility would provide either power supply or power demand for certain periods of time to support the stable operation of the power grid.

Is energy storage a'renewable integration' or 'generation firming'?

The literature on energy storage frequently includes “renewable integration” or “generation firming” as applications for storage (Eyer and Corey, 2010; Zafirakis et al., 2013; Pellow et al., 2020).

What are the four main roles in the electricity value chain?

As for the market role, we differentiate between the four main roles in the electricity value chain: trading, production, transmission and distribution (T&D), and consumption (Zucker et al., 2013). In trading, the investor would buy electricity from producers or the market and sell it to consumers or the market.

Should energy storage be a 'bolder' approach?

Bolder approaches could include the design of special electricity tariffs for investors in a consumer role that unlock the ability of energy storage to mitigate unexpected demand peaks (Peak Shaving) and balance conventional demand patterns (Consumption Arbitrage) (Fridgen et al., 2018).
