A coal shortage is affecting power plants in India, with several states, including Delhi, raising concerns over possible blackouts.

The shortage has been blamed on a hike in global coal prices.

Power plants across the country have started to slow power generation after stocks ran low.

Over half of the country's 135 coal-fired power plants, which in total supply around 70 per cent of the nation's electricity, have fuel stocks of less than two days, according to the power grid operator.

Tata Power Distribution Ltd (TPDDL), which supplies electricity to parts of the national capital, on Saturday warned of intermittent rotational power cuts.

The huge coal shortage affecting power plants will be handled in the next few days, the Centre said as several states, including Delhi, raised concerns over impending blackouts. The shortage is due to a hike in global coal prices, the Centre said.

Power plants across the country regulated generation after stock ran low. Against the requirement of maintaining 15 days to 30 days of stocks, over half of the country's 135 coal-fired power plants, which in total supply around 70 per cent of the nation's electricity, have fuel stocks of less than two days, as per the data from the grid operator.

Tata Power Distribution Ltd (TPDDL), which supplies electricity to parts of the national capital, on Saturday warned of intermittent rotational power cuts as units supplying electricity to Delhi discoms have coal stocks to meet generation requirements for 1-2 days, its CEO Ganesh Srinivasan said.
