6 FAQs about [What are the indicators of energy storage]
Does thermal energy storage have a key performance indicator (KPI)?
Recently, the technology roadmaps carried out in thermal energy storage or in energy applications including TES identify KPI for TES. Unfortunately, this first attempt has been done individually and no comparison has been carried out. A key performance indicator (KPI) is a performance measurement that evaluates the success of a particular activity.
What is the scope of the energy indicator?
The scope of the indicator is to consider which part of the total energy required by the building/group of buildings (or by a specific function, such as heating or artificial lighting) and/or the generation from RES, during a certain period, is stored-in and then released from the storage system.
What are key performance indicators?

What are the main KPIs for the assessment of ESSs in buildings?
The main KPIs to allow the assessment of ESSs in buildings are presented and descried below. 1. Storage capacity This is the quantity of stored energy in the storage system or available immediately after it is completely charged.
What is storage capacity?
For instance, storage capacity, one of the most used indicator, is defined as the energy that can be stored in reference conditions ( Komarnicki, Lombardi, & Styczynski, 2017), or the quantity of available energy which can be retrieved without negatively affecting the storage device (Ibrahim et al., 2007 ).
What is an energy storage system (ESS)?
In general, the most common applications of ESSs for power uses in buildings are “energy-intensive”, that means they are typically suited to store/release energy during time periods that range from minutes (short-term) to months (seasonal) and are not designed to manage power peaks ( Chatzivasileiadi, Ampatzi, & Knight, 2013).
