Neutrino oscillations in matter offer a novel path to investigate new physics. The most recent data from the two long-baseline accelerator experiments, NO$\nu$A and T2K, show discrepancy in the standard 3-flavor scenario. Along the same line of discussion, we intend to explore the next generation of long-baseline experiments: T2HK and DUNE. We investigate the sensitivities of relevant NSI couplings ($|\epsilon_{e \mu}|$, $|\epsilon_{e \tau}|$) and the corresponding CP-phases ($\phi_{e \mu}$ and $\phi_{e \tau}$). While both the experiments are sensitive to non-standard interactions (NSI) of the flavor changing type arising from $e-\mu$ and $e-\tau$ sectors, we show that DUNE is more sensitive to these NSI parameters when compared to that of T2HK. At the same time, we aim to explore the impact of non-standard neutrino interaction on the sensitivity of standard CP-phase $\delta_{CP}$ and atmospheric mixing angle $\theta_{23}$ in the normal as well as inverted hierarchies. Our analysis also exhibits the difference in probabilities for both the experiments with inclusion of NSI.
