The grand coulee power development

The grand coulee power development is a part of the Columbia Basin Project which is primarily an irrigation enterprise. The Grand Coulee dam raises the water level in the Columbia River over 300 feet, but a tremendous amount of power is required to raise water an additional 300 feet for irrigation purposes. This power requirement can be met largely by off-peak power developed at the Grand Coulee power plant consisting of two powerhouses which will have an ultimate installation of almost 2,000,000-kva generating capacity.
