The progress on the construction of the stadium has been hit by a number of delays in recent weeks and months, repeatedly forcing Spurs to put back in grand opening.
However, according to the aforementioned source, the club now have a firm date in mind for the occasion.
The Premier League game against Palace on March 16 is the game that has been identified as the perfect opportunity by Spurs bigwigs, though that plan could yet not come to fruition.
Should Spurs progress deep into the FA Cup the Palace game will be postponed due to the fixture clash, meaning it will not be played until April.
Senior club officials are believed to have met with contractors Mace to discuss the progress on the building work on Sunday.
Fans hoping for a north London derby stadium inauguration look set to be disappointed, though, with the police thought to be opposed to plans for the visit of Arsenal to be Tottenham's first game at their new home.
Should the Palace game fall through it is thought that the visit of Brighton on April 6 would be the next best option.
