Vedanta Resources plc is not just a major metals producer – it’s also well on the way to being one of India’s most important energy providers and power traders. If its grandiose plans are allowed to materialise the UK-listed company will soon rank as the country’s fourth most important oil outfit, having taken over Cairn India from its UK parent. Through its subsidiary, Sterlite, Vedanta is constructing a coal-fired power plant to serve its expanding Jharsuguda aluminium smelter in Orissa. But the plant is slated to deliver three times as much electricity to the country’s national grid, from what might become the largest carbon-emitting facility of its kind in India.
