It could have been  several kilowatts  less or more
than that.
Anycase,the ballpark is there I think.
Actually,in CSN there is his note regarding
preparation for CS transmitter  working at ~50 hp
supply capacity (little less than 50 kw).
On the other hand,Westinghause transformer rating was
60 kVA  and Tesla put a remark  it could have been
loaded ,if necessary and for a short period of
time,2-3 times that value without overheating.

These figures are to be compared with ~10 meter point
to point spark,apparently the longest stricking
distance Tesla achieved by the machine , and
L::SQRT(P) requirements  for that.However,an
efficiency may have play its role and it is not sure
if 10 m spark was established by 40,60 or 90 kW input.


One must be aware Tesla sometimes talks in terms of
Megawatt powers consumption of CS coil,but these would
be impulsive RF powers.
Unrealistically high Qs of the coil Tesla used in his
calculations could be another source of various
errors.
Q pumping modes were out of reach for him at the time
anyway.

All the Best,
