The IREP, expected to be completed by May 2016, will yield approximately 1.4 million tonnes per annum (MTPA) of petcoke, which can be used to produce around 500-600 MW of power.
Petcoke is a high calorific value solid fuel and is extensively used for power generation in various countries.
INKEL, Kerala's PPP model infrastructure development company, which undertook the feasibility study for the project in March, 2014, had submitted a comprehensive report, which endorsed the implementation of the project.
