As the sun sets in a small village in Eastern Uttar Pradesh, it's lights out. In huts and in small neighbourhood shops, kerosene lamps flicker. The rub lies in the fact that barely a five-minute walk away is the Rihand Dam, one of the largest in the country. Embedded around it are as many as 10 power plants, some operated by the centre and others by the state government, that collectively generate over 10,000 megawatts of electricity.
