Needle coke is the main raw material for GE production & is very critical for the growth of GE industry.

“Due to excess capacity of needle coke in the recent past, some of the needle coke producers have been trying to find a new application for coke in the Lithium Ion batteries. In the last couple of years, needle coke has been successfully used in this application and a reasonably large part of needle coke is now being used in China in Lithium Ion batteries”, HEG said in an investor presentation on January 10, 2019.

With the sudden increase in demand for GE, needle coke availability has become a bottleneck. The company said all Global GE manufacturers are not able to operate beyond 85-90 per cent capacity utilization. One of the largest producers of needle coke is debottlenecking its capacity enabling them to increase its production by around 50-60,000 mt, it added.

This is likely to be on stream in the second half of 2018 and should help the Graphite Industry to some extent for short term Q42018 onwards, it added.

“Supply constraints in needle coke would mean lower capacity addition in the next two years. The quadrupling of needle coke prices, from $1,000 a ton, and mounting demand would lead to higher selling prices of graphite electrodes, of up to $14,000 a tonne in FY19. Any decline in steel prices would eat into realisations and EBITDA”, analysts at Anand Rathi Share and Stock Brokers said in company update.

“The sluggishness in the user, the steel industry, would cut into volume growth. The needle coke is the key raw material. An increase in its prices would eat into profitability”, the brokerage said November 2018, Graphite India note.
