The Cabinet's plan was estimated at the time to cost US$3.16 billion and was expected to generate 25,000 MW. A report from late April 1958 stated that excavation work would hopefully begin by midyear, with 1964/1965 as the year set to bring the initial stage to completion. Plans called for three stages of construction, beginning with a 1,500 MW plant with a $320 million price tag, then twice.
