  We investigate the prospects of next-generation neutrino oscillation
experiments DUNE, T2HK and JUNO including TAO within Standard Model Effective
Field Theory (SMEFT). We also re-interpret COHERENT data in this framework.
Considering both charged and neutral current neutrino Non-Standard Interactions
(NSIs), we analyse dimension-6 SMEFT operators and derive lower bounds to UV
scale $\Lambda$. The most powerful probe is obtained on ${\cal
O}_{{ledq}_{1211}}$ with $\Lambda \gtrsim$ 450 TeV due to the electron neutrino
sample in T2HK near detector. We find DUNE and JUNO to be complementary to T2HK
in exploring different subsets of SMEFT operators at about 25 TeV. We conclude
that near detectors play a significant role in each experiment. We also find
COHERENT with CsI and LAr targets to be sensitive to new physics up to
$\sim$900 GeV.
