This report gives the full findings from a research project carried out by APRS between August and November 2025, into Battery Energy Storage Systems (BESS) in Scotland.

The report includes the process for determining applications and grid connections, the distribution of current and future developments, current UK and Scottish Government policy covering renewable energy infrastructure, and an analysis of decision making in planning applications. Our findings draw on publicly available data, which we have brought together to do some new analysis. The report concludes with a set of policy recommendations requiring urgent consideration in light of the evidence.
