Ministry of Power is likely to launch a Rs 1000-crore scheme for encouraging energy efficiency in micro-, small- and medium-enterprises (MSMEs), a government official, as cited in an ET report, said. Government will provide financial support in the form of interest subvention. Small enterprises will get an interest subsidy of 5 per cent while medium ones will receive 3 per cent of subsidy on loans taken to implement energy-efficient technologies, according to the report.
