A site’s installed capacity can change over time due to factors such as the addition or decommissioning of wind turbines or solar panels. Additionally, available capacity may fluctuate due to technical issues or maintenance periods when some capacity is temporarily unavailable. These capacity changes can be reflected by uploading the periods of change along with the updated capacity values. Ensure that the capacity values are provided in kilowatts [kW].
