Are energy storage systems suitable for grid applications?

Toward that end, we introduce, in two pairs, four widely used storage metrics that determine the suitability of energy storage systems for grid applications: power & capacity, and round-trip eficiency & cycle life. We then relate this vocabulary to costs. The power of a storage system, P, is the rate at which energy flows through it, in or out.

What is the power of a storage system?

The power of a storage system, P, is the rate at which energy flows through it, in or out. It is usually measured in watts (W). The energy storage capacity of a storage system, E, is the maximum amount of energy that it can store and release. It is often measured in watt-hours (Wh). A bathtub, for example, is a storage system for water.
