NTPC Kudgi Su­per Ther­mal Power Project’s (STPP) first unit of 800 MW is set to com­mence com­mer­cial pro­duc­tion in Septem­ber. “Cur­rently, the plant is un­der test phase and is set for com­mis­sion­ing in May, but is ex­pected to be­gin com­mer­cial pro­duc­tion not ear­lier than Septem­ber this year,” Sub­ha­sis Ghosh, Re­gional Ex­ec­u­tive Di­rec­tor (west-i), NTPC, said.

“Since Kudgi is a green­field project and big­gest among the com­pany’s power gen­er­at­ing as­sets, we may take six months for com­mer­cial pro­duc­tion af­ter se­ries of tests,” he added.

Kudgi STPP is be­ing built at a cost of Rs. 15,166 crore, with Toshiba of Ja­pan, Doosan of Korea and L&T as EPC con­trac­tors, and will gen­er­ate 2400 MW, in the first stage with three units of 800 MW each and the bal­ance in sec­ond stage with a to­tal ca­pac­ity of 4000 MW.

Ghosh said, “Cur­rently, for test­ing and com­mis­sion­ing of Kudgi plant, we are us­ing coal from Sin­gareni Col­lieries on a tem­po­rary ba­sis. Once the rail­way sid­ing is con­structed at Kudgi, coal from Bhalu­munda (Ch­hat­tis­garh) will be utilised.”

The plant lo­cated at Vi­jaya­pura (Bi­japur) in north Kar­nataka is pri­mar­ily en­vis­aged to meet the en­ergy needs of four south­ern states pro­por­tion­ately, with Kar­nataka get­ting 50 per cent of the to­tal power pro­duc­tion. The Kudgi plant is de­signed with su­per crit­i­cal units with high ef­fi­ciency. The tech­nol­ogy has a cy­cle ef­fi­ciency of around five per cent more than the con­ven­tional sub­crit­i­cal tech­nol­ogy and con­sumes 8-10 per cent less fuel.

“This re­sults in con­se­quent re­duc­tion in green­house emis­sions. The plant is de­signed with elec­tro static pre­cip­i­ta­tors with 99.97 per cent ef­fi­ciency which cap­tures the fly ash gen­er­ated out of coal com­bus­tion within the plant and fa­cil­i­tates for ash util­i­sa­tion,” said Bala­ji­iyen­gar, Group Gen­eral Man­ager, NTPC Kudgi STPP. “We have also put in place ash util­i­sa­tion plan. As per the plan, we will be pro­vid­ing ash to end-user in­dus­tries like ce­ment and brick units. We have called for EOI and have re­ceived 14 ap­pli­ca­tions mainly from the ce­ment in­dus­tries in the re­gion,” he added.
