Scope and content
Scenic views from Eastern Washington. An aerial view of the town on the far side of the river and Grand Coulee Dam plant facilities in the foreground. A tower for delivering electric power from the plant is seen on the right as others climb the hill from below. Electrical energy generated at the power plant at 13,800 volts is stepped up to 230,000 volts for long distance transmission by groups of transformers. High tension lines from the transformers are carried on steel towers over the powerhouse and up the canyon walls to a switchyard, where facilities are provided for interconnecting generating units and transmission lines.
