Assam-based Numaligarh Refinery Limited (NRL) has started supplying BS-VI grade motor spirit and high speed diesel from its refinery. NRL has asserted that it had commissioned a diesel hydro treater plant in 2018 at a project cost of around Rs 10 billion. The plant is capable of producing BS-VI grade diesel. Recently, NRL invested around Rs 1.25 billion for revamping its motor spirit plant to meet BS-VI specifications for petrol. The plant was commissioned in January 2020. NRL has also embarked on a massive expansion plan (from 3 million tonnes per annum [mtpa] to 9 mtpa) to produce BS-VI compliant fuels from its new facilities.
