Energy storage project classification standards

What are the different types of energy storage systems?

*Mechanical, electrochemical, chemical, electrical, or thermal. Li-ion = lithium-ion, Na–S = sodium–sulfur, Ni–CD = nickel–cadmium, Ni–MH = nickel–metal hydride, SMES=superconducting magnetic energy storage.

What is energy storage system?

Source: Korea Battery Industry Association 2017 “Energy storage system technology and business model”. In this option, the storage system is owned, operated, and maintained by a third-party, which provides specific storage services according to a contractual arrangement.

Does industry need standards for energy storage?

As cited in the DOE OE ES Program Plan, “Industry requires specifications of standards for characterizing the performance of energy storage under grid conditions and for modeling behavior. Discussions with industry pro-fessionals indicate a significant need for standards ...” [1, p. 30].

What is an electrical storage system?

Japan uses the term “electrical storage systems” in its technology standards and guidelines for electrical equipment to refer to electromechanical devices that store electricity. In the case of the US, the equivalent term is “rechargeable energy storage systems,” defined in its National Electrical Code (NEC).

How are grid applications sized based on power storage capacity?

These other grid applications are sized according to power storage capacity (in MWh): renewable integration, peak shaving and load leveling, and microgrids. BESS = battery energy storage system, h = hour, Hz = hertz, MW = megawatt, MWh = megawatt-hour.

Do energy storage devices need a participation framework?

Foundationally, energy storage devices need a participation framework for operating and seeking remuneration within the power system. To that end, various market rule changes may be required for energy storage resources to be able to participate.
