A recent observation by the EDGES collaboration shows a strong absorptionsignal in the global 21-cm spectrum from around a redshift of $z = 17$. Thisabsorption is stronger than the maximum prediction by existing models andindicates that the spatial fluctuations of the \HI 21-cm brightness temperatureat Cosmic Dawn could be an order of magnitude larger than previously expected.In this paper, we investigate the prospects of detecting the \HI 21-cm powerspectrum from Cosmic Dawn using uGMRT. We find that a $10\sigma$ detection ofthe enhanced \HI 21-cm signal power spectrum is possible within $70, 140$ and$400$ Hours of observation for an optimistic, moderate and pessimistic scenariorespectively, using the Band-1 of uGMRT. This could be an useful probe of theinteraction between the baryon and dark matter particles in the early Universe.We also present a comparison of the uGMRT predictions with those for the futureSKA-Low.
