NELLORE, India — India has long struggled to provide enough electricity to light its homes and power its industry around the clock. In recent years, the government and private sector sought to change that by building scores of new power plants.
But that campaign is now running into difficulties because the country cannot get enough fuel — principally coal — to run the plants. Clumsy policies, poor management and environmental concerns have hampered the country’s efforts to dig up fuel fast enough to keep up with its growing need for power.
A complex system of subsidies and price controls has limited investment, particularly in resources like coal and natural gas. It has also created anomalies, like retail electricity prices that are lower than the cost of producing power, which lead to big losses at state-owned utilities. An unsettled debate about how much of its forests India should turn over to mining has also limited coal production.
The power sector’s problems have substantially contributed to a second year of slowing economic growth in India, to an estimated 7 percent this year, from nearly 10 percent in 2010. Businesses report that more frequent blackouts have forced them to lower production and spend significantly more on diesel fuel to run backup generators.
