The La Liga encounter between the local rivals had been due to start at 8.30pm in the Spanish capital.
However, kick off now could be postponed for over an hour amid rumours that the floodlight cables have been deliberately cut by disgruntled home fans at the stadium.
Defending champions Madrid currently sit 14th in the La Liga table, while Vallecano are seventh.
