A Power Tower was a power station in Mega-City One which drilled down to the magma beneath the Earth's crust, extracting the energy to fuel the city[1]. Geothermal power was carried from beneath the crust to the city by plasteel tubes which ran up through the Undercity[2].

It was a source of geothermal energy for more than half of the city. Molten lava was drawn lave from the Earth's core which was contained by a computerised magnetic field system[3].

In 2101, the Southern Electricity Generating Complex was attacked by the Doomsday Dogs, ordered by Father Earth[4].
