Railway freight traffic officials denied a comment on the rake position.
The supply crisis in coal has particularly impacted the industries in steel, aluminium and ferro alloys sector who bank on their captive power supplies to ensure competitive pricing of products. The CPPs are mostly getting thermal coal from Coal India Ltd (CIL) subsidiary Mahanadi Coalfields Ltd (MCL) and lesser quantities from the other subsidiary- South Eastern Coalfields Ltd (SECL).
For instance, Talcher Coalfields under MCL's command area needs 45 rakes each day for smooth evacuation of coal. Against this, only 30 rakes are made available. With IPPs getting precedence in coal supplies, the backlog for other categories of power consumers has built up.
MCL officials could not be reached for their comments.
For CPPs, importing costlier coal is not a viable or sustainable option.
"Despite several representations made to MCL and Railways, the coal supply position has not improved. Even after making timely payments against allotted quantities, coal delivery is still pending. This is not only blocking huge amount of our expensive working capital but has forced us to import equivalent quantity of coal to sustain our operations", said an official with a steel company.
For the power guzzling aluminium industry, opting for coal imports is even more unsettling. Power contributes around 40 per cent to the making cost of aluminium. Vedanta is facing shutdown of some of its power units due to a pollution board order and the worsening coal supplies have dealt a blow.
"Unavailability of sufficient railway rakes has caused intermittent disruptions in our operations. If tis crisis deepens, we fear we may have to depend on imports", said a Vedanta Ltd official.
Vedanta runs 1215 Mw CPP and also has 2400 Mw coal-fired station in the vicinity of its aluminium smelting complex at Jharsuguda. Of the 2400 Mw capacity, Vedanta can use up to 1800 Mw for its captive consumption.
Even the government owned aluminium maker Nalco is not spared from coal supply bottlenecks.
"Against our daily requirement of 20,000 tonnes of coal per day, we are hardly getting 8000 tonnes. The rakes are not available. Also, we are not getting coal through the Merry Go Round system. Our coal stock is also rapidly exhausting", said a Nalco source.
Captive Generating Plants in Odisha have a combined installed capacity of 9760 Mw. Major generators are Vedanta (1215 Mw), Nalco (1200 Mw), Aditya Aluminium (900 Mw), Jindal Steel & Power Ltd (810 Mw) and Bhushan Steel (740 Mw).
