About Jamesfield

Jamesfield is a battery storage site near Abernethy in Perth and Kinross. It began operating in February 2024.

Its 49 MW of registered generating capacity is spread across 2 balancing mechanism units. Every half hour each unit tells the grid how much it will generate (its physical notification): that is the live figure above, and GridMonkey has recorded it every half hour since it was added to the list in October 2026, for the chart.

Battery stations charge when power is cheap and plentiful and discharge at the peaks, in seconds. Their output swings between charging and discharging through the day.
