Power generation decelerated 4.7 per cent year-on-year (Y-o-Y) to 155 billion units (BU) in August 2024.This was the first downtrend in many years, albeit on a high base - generation had increased 19 per cent Y-o-Y to 163 billion units (BU) in August 2023.The dip was partly due to excess rainfall, which pared cooling demand and also reduced need for irrigation.
