The Indian government is planning to use coastal shipping to transport coal in order to reduce logistics costs and power costs. This would involve transporting the coal from mines to ports via rail, shipping it along the coast to another port, and then carrying it from the port to the plant site. The shift to this rail-sea-rail (RSR) route could potentially save up to Rs 1,300 per tonne in logistics costs. The coal ministry aims to supply 112 million tonnes of coal by 2030 through coastal shipping. This mode of transportation is seen as economical and eco-friendly.
