IEEE 1679-2020

IEEE 1679-2020 is a technical standard for characterizing and evaluating energy storage technologies in stationary applications. It provides a structured way to assess how storage systems behave under defined conditions, helping engineers and procurement teams compare performance with greater consistency. For power and energy projects, that matters because stationary storage choices can affect reliability, operating cost, and system integration. The document is especially useful when selecting or specifying technologies for grid-supporting or facility-based energy storage.

Overview of IEEE 1679-2020

IEEE 1679-2020 focuses on the methods and criteria used to evaluate energy storage technologies intended for stationary service. Rather than prescribing one storage type, it supports a consistent technical framework for describing characteristics such as performance behavior and application suitability. This makes the standard relevant to engineering, testing, and specification work where comparisons must be based on repeatable and transparent assessment. For organizations working with storage in power systems, it helps create clearer technical expectations.

Typical use cases

This standard is commonly used when assessing batteries, hybrid storage systems, or other stationary energy storage technologies for utility, industrial, or facility power applications. It may support feasibility studies, vendor evaluations, acceptance testing, and system design reviews where storage performance needs to be documented in a consistent way. IEEE 1679-2020 is also useful in procurement and project planning when teams need a common technical basis for comparing options across power, energy, and industry applications.

Why it matters

In stationary storage projects, inconsistent evaluation methods can lead to poor technology selection, unclear performance claims, and avoidable integration risk. IEEE 1679-2020 helps reduce that uncertainty by supporting more consistent characterization and evaluation practices. That can improve design control, strengthen testing and documentation, and make compliance or procurement decisions easier to defend. For stakeholders responsible for reliability and lifecycle value, the standard provides a practical reference for comparing technologies on a more equal basis.
