But the proposed hike in electricity duty for CGPs, which will make it costlier than the rate of levy collected on the power sourced from distribution companies, is expected to increase the cost of production of aluminium by Rs 4,000-5,000 a tonne and that of ferrochrome by at least Rs 1,000 per tonne.
Odisha has half the nation’s aluminium capacity and nearly 80 per cent of the ferrochrome capacity.
The electricity duty for CGPs was increased from 12 paise a unit to 20 paisa in 2001 and then subsequently revised to 30 paisa a unit in 2015. However, in an amendment to the electricity Act in November, 2016, the Odisha government kept the option open to increase the electricity duty for CGPs up to Rs 2 a unit.
“Aluminium being a power guzzling industry, we had set up a captive power plant with an aim to access cheaper power. The capital investment in a large size thermal power plant is about Rs 5 crore a megawatt (Mw). We made substantial investment on our captive generation. Now, the advantage will be taken away by increase in the electricity duty,” said an official of an aluminium company wishing not to be named. Aluminium requires approximately 15,000 units of power for one tonne of metal while energy uses for ferrochrome units comes to about 4,000 units a tonne.
Drawing a comparison between CGPs and Independent Power Producers (IPPs), the official said, IPPs who get preference of land, water and allocation of coal at reserve price do not pay electricity duty as the same is charged to consumers directly by the state-owned bulk power supplier GRIDCO or the distribution companies (distcom). IPPs also get benefit of FSA and assured supply of coal whereas CGPs source coal through auction or private arrangement.
The current CGP capacity in Odisha, across all industries, is 7500 Mw. The IPPs and state owned Odisha Power Generation Corporation (OPGC) have a collective capacity of 3270 Mw. Other than this, Odisha has access to its share from 3460 Mw produced by NTPC in the state, 600 Mw of hydro-power and less than 100 Mw of renewable energy.
Sources said, the government is increasing electricity duty on CGPs basically to discourage captive generation, particularly in the backdrop of surplus power availability and stagnating demand from industrial consumers. The proposal for duty hike for captive generating plants which has been recommended by the state energy department is now pending for approval of the chief minister.
