New Partnership Agreement Reached to Further Development of Nuclear Reactors in Texas

LCG, May 11, 2010--Nuclear Innovation North America LLC (NINA), the nuclear development company jointly owned by NRG Energy, Inc. and Toshiba Corporation, announced yesterday that it reached an agreement with The Tokyo Electric Power Company, Inc. (TEPCO) to partner in the installation of two nuclear units at the South Texas Project.

Today, the South Texas Project (STP) includes two operating nuclear units and is located about 90 miles southwest of Houston. The existing two units are pressurized water reactors, each with a capacity of 1,312 MW. The site and cooling reservoir were originally designed for four units, and the current plans are to build the new units adjacent to the existing units.

In February 2009, Toshiba announced that it signed an engineering, procurement and construction (EPC) agreement for the addition of two nuclear units that are scheduled to commence operations in 2016 and 2017. The electric generating capacity of each new unit will be approximately 1,360 MW.

According to the press release, a conditional commitment under the Department of Energy (DOE) loan guarantee program is sought by NINA, along with additional loan guarantees through the Japanese export credit agencies. Given a conditional commitment for the DOE loan guarantee is secured, TEPCO will invest $155 million for a 10% share of NINA Investments Holdings' interest in the new units.

With the new agreement, TEPCO will hold a 9.2375% interest in the new units, raising NINA's share to 83.1375%, with CPS Energy's share at 7.625%.
