The power for the governor pumps, motor-generatorsets, station lighting, elevator, etc., is taken from the 12,000volt generator buses to a hank of three 250 transformers.

The superstructure has been built throughout of high-grade fire-proof materials, the framework being of steel,with walls, floors and structures for the electrical apparatus,of reinforced concrete. The ultimate development is forsix generators with total capacity of horsepower. The generators, of which there are already two installed,are rated at 10,600 , 80 per cent, power-factor, :J-phase,12,000 volts, 60 cycles. They are 26 feet in diameter.
