India is considering maintaining strategic reserves of natural gas and imported coal to address future supply shocks, a senior power ministry official said on Thursday, as the energy hungry nation battles a crippling coal shortage.

       A surge in power demand combined with a fall in imports due to high global coal prices have lead to supply disruptions and power cuts lasting up to 14 hours a day, despite record supplies from state-run Coal India, the world's biggest coal miner.

       Alok Kumar, India's power secretary, said countries increasingly meet their own needs first when there is a supply crunch, citing the example of Russia curtailing supplies to European nations because they wanted more gas locally.
