The company said total coal availability across the system stands at 168 million tonnes. This includes 47.6 MT of coal stock at domestic coal-based power plants, 113.5 MT inventory at Coal India mine heads, nearly 3 MT at transit points, and around 4 MT of coal currently in transit through railway movement.
Coal India added that around 50 MT of in-situ mine coal remains available for quicker extraction if demand increases further.
According to the company, coal stock compression at thermal plants during peak summer is a seasonal occurrence and not necessarily linked to supply disruptions.
