Energy management system

The site-level controller of a storage system that decides when to charge and discharge according to prices, grid signals and the battery’s limits, and dispatches those commands to the BMS and inverters.

Flow battery

A battery whose energy is stored in liquid electrolytes held in external tanks and pumped through a reaction stack. Energy and power scale independently, which suits long-duration grid storage; vanadium is the most developed chemistry.

IEC 62933

The IEC series for grid-integrated electrical energy storage systems, written at system level whatever the storage technology: part 2-1 defines unit parameters and test methods, part 5-1 gives general safety considerations, and part 5-2 adds safety requirements for battery-based systems over their whole life, from design to decommissioning.

IEEE 1679 and 1679.1

IEEE’s recommended practice for characterising and evaluating energy storage technologies in stationary applications, with a companion guide, 1679.1, for lithium-based batteries, revised in 2025. They give a structured way to judge a technology — description, ageing and failure modes, safety, evaluation methods and regulatory issues — before choosing it for a site.

Stationary storage

Batteries installed in a fixed place — a container at a solar farm, a cabinet in a home — to shift energy in time or support the grid. LFP cells dominate because cost per cycle and safety matter more than mass.
