scope:

This Recommendation identifies the main needs and applications of stationary electrical energy storage for information and communication technology (ICT) sites such as back-up on different grid quality and cyclic use of renewable energy systems. It also provides possible selection criteria for the correct choice for the end system. The topics considered are:

- families of electrical energy storage, such as batteries or supercapacitors;

- technologies types and their main properties;

- adaptation to requirements (e.g., functionalities, technology availability, electrical characteristics, environmental adaptation, maintenance type, cost);

- national or regional rules and regulations.

The Recommendation highlights the need for evaluation methods that are complementary to existing battery standards as they allow different time-frames including shorter tests compared to common energy storage industry tests.

This Recommendation is Part 1 of a series of Recommendations that cover energy storage technologies (e.g., battery, supercapacitor) applicable to stationary telecom/ICT equipment used in telecom networks, data centres and customer premises equipment (CPE).
