Where to get the energy storage value

How do you value energy storage?

Valuing energy storage is often a complex endeavor that must consider different polices, market structures, incentives, and value streams, which can vary significantly across locations. In addition, the economic benefits of an ESS highly depend on its operational characteristics and physical capabilities.

How is the value of electricity storage assessed?

The value of electricity storage is assessed by comparing the cost of operating the power system with and without electricity storage. This framework also describes a method to identify projects where the value of integrating electricity storage exceeds the cost to the power system.

Where does storage value come from?

The value of electricity storage comes from various sources. A significant portion of it is expected to come from deferral of other investments, such as peaking plants or transmission and distribution (T&D) investment, especially in systems where electricity demand is growing or where variable renewable energy (VRE) constitutes a significant share of electricity generation.

Why is electricity storage valuable?

Electricity storage, when connected at the distribution level, provides various services such as improving power quality and reliability, deferring distribution capacity investment, and supporting integration of distributed renewable energy.

What are energy storage systems?

Energy storage systems (ESSs) deployed at different levels of the electrical grid serve different functions. For example, a BESS located at a distribution substation may offer both ancillary-based and distribution-based benefits.

What is one value stream of storage systems?

Storage systems provide several value streams, one of which is energy arbitrage, which consists of charging the storage system with VRE when electricity is inexpensive and discharging it to the grid when it is expensive. One viable solution is to use storage systems to provide flexibility and make the grid more efficient.
