Abstract: Pumped storage hydroelectric projects are assuming an important role in the supply of electric power in the United States. Their operating characteristics are ideally suited for serving peak power loads, and to complement the base load power being derived from today's large efficient fossil and nuclear fueled steam-electric plants. Development of the reversible pump turbine has enhanced the feasibility of pumped storage projects. Six major projects have been placed in operation since 1961; seven are under construction; and applications for 10 projects are pending before the Federal Power Commission. The pumped storage capacity of these installations totals more than 12,000,000 kw. Large amounts of new peaking capacity will be needed in supplying the country's growing electric power loads. Much of this capacity will be provided through development of pumped storage hydroelectric projects at the many favorable sites that are available. Plans for developing a number of new sites are already under way.
