NEW DELHI (Reuters) -India's northeastern state of Assam has withdrawn its flagship clean energy policy announced in February, according to a document reviewed by Reuters and sources with direct knowledge of the matter, clouding millions of dollars of planned investments. Earlier this year, Assam, the largest state in India's northeast, sought to attract investments to a region that has lagged in renewable energy adoption by offering financial incentives and waivers. The February policy offered subsidies on power transmission and eased bank guarantee requirements to support clean energy projects in the state.
