Why is energy storage valuation important?

net positive benefit that meets the return on investment criteria, no further analysis is required. Therefore, as the application space for ESSs grows, energy storage valuation is of a particular interest of many energy storage stake holders (e.g., ESS owners, system operators, regulators, and researchers).

Can software tools be used for valuing energy storage?

Taking advantages of the knowledge established in the academic literature and the expertise from the field, there are efforts from multiple parties (e.g., national laboratories, utilities, and system integrators) in developing software tools that can be used for valuing energy storage.

What are ESS valuation tools?

In ESS valuation tools, the optimizations are usually for finding the charge and discharge schedule of an ESS to maximize its revenue from providing certain services given its energy and power ratings and its round-trip efficiency.

How does cost analysis affect energy storage deployment?

While all deployment decisions ultimately come down to some sort of benefit to cost analysis, different tools and algorithms are used to size and place energy storage in the grid depending on the application and storage operating characteristics (e.g., round-trip efficiency, life cycle).

Does energy storage need a dynamic simulation tool?

For energy storage applications focused on improving the dynamic performance of the grid, an electromechanical dynamic simulation tool is required to properly size and locate the energy storage so that it meets the desired technical performance specifications.

How do you categorize energy storage services?

Another approach for categorizing storage services is by the governing rate tariff or market rules. This results in three categories: behind-the-meter (BTM) applications, front-of-the-meter (FTM) applications (e.g., market areas), and operation in a vertically integrated utility. A summary of energy storage applications is given in Table 1.
