See the very 1st thing is bundle sheath cell shows very less concentration of Grana, hence we say Grana is absent, the required amount of ATP & NADPH2 are also transported from mesophyll cell to bundle sheath cell via plasmodesmata.
I am not sure about the source of ATP but I can tell you something about NADPH. The conversion of malate to pyruvate and CO2 by malic enzyme is carried out in the bundle sheath cell. This process produces NADPH.
