With gas turb<strong>in</strong>e thermal match (GTTM) option, about 320 per cent excess electricity is<br />
generated, which has to be sold as <strong>in</strong> the RETM option. Gas turb<strong>in</strong>e power match (GTPM)<br />
option takes care <strong>of</strong> all the power needs though heat deficit is as high as 60 per cent. This<br />
will require the adoption <strong>of</strong> auxiliary natural gas fir<strong>in</strong>g <strong>in</strong> the recovery boiler.<br />
Accord<strong>in</strong>gly, the sensitivity analysis carried out to see the impacts <strong>of</strong> the <strong>in</strong>crease <strong>in</strong> the<br />
<strong>in</strong>vestment, fuel <strong>and</strong> electricity price escalation, was limited to STPM, REPM <strong>and</strong> GTPM<br />
options.<br />
