No, one megawatt ERP sounds reasonable. An antenna gain of uo to 12dB would be usual which means that the transmitter would be delivering 1/16 x 1,000,000 = 62,500 watts.

Analog UHF transmitter ERPs up to about 2megawatt were not uncommon. DTV transmitters now frequently emit up to 1 Megawatt average radiated power using two or three 20kW to 35kW I.O.T's (Inductive Output Tubes). Yes, Vacuum Tubes are used for DTV.
