STP Units 3 & 4


Leading the Industry's Renaissance
The first new nuclear power plants in the U.S. in nearly three decades in all likelihood will be built at STP. We already have applied for a federal license to build and operate two new units, the first such application submitted to the Nuclear Regulatory Commission in 29 years.

STP is well suited for new construction. It has the necesary site license, water resources and infrastructure, as well as excellent management and the strong support of its neighbors and surrounding communities. In addition, Texas has a critical need for more electrical generation capacity.

Proven, Dependable Design
Each of the new units will hold a 1,350-megawatt Advanced Boiling Water Reactor (ABWR), the latest advancement in a plant design with a half-century history of safe and reliable operations worldwide. The ABWR also has a proven track record of being built on time and within budget, with four ABWRs already online in Japan, four more under construction there and in Taiwan, and eight additional units on order. When Units 3 & 4 are operational, they will double the STP's output and make it the largest nuclear power plant in the U.S.

Environmental, Economic and Community Benefits
