Indian Railways has decided to set up four bio-diesel esterification plants for production of bio-diesel. The first two bio-diesel esterification plants with a capacity of 30 tonnes of bio-diesel per day are being set up at Tondiarpet and Raipur at the cost of र29.99 crore and र29.98 crore respectively. Raipur and Tondiarpet bio-diesel esterification plants are expected to be commissioned by 2013. The locations for the remaining two plants are under finalization. Solar PV modules and windmill power plants are likely to be operational within next two-three years subject to availability of funds.
