"This guidance document is primarily tailored to ‘grid scale’ battery storage systems and focusses on topics related to health and safety. There is no specific definition of ‘Grid Scale Storage’ however for the purposes of this guidance document, this is assumed to be systems with an installed capacity of 1MW or greater.
The guidance covers both stand-alone open-air sites, and storage co-located with large scale generation or demand, although it is noted that co-located storage introduces design complexity and variability which cannot be fully reflected in a general guidance document."
