MONCKS CORNER — Santee Cooper has lined up another possible buyer for part of its stake in two new nuclear units under construction in the Midlands.

The state-owned utility announced Tuesday it has signed a letter of intent with American Municipal Power Inc. to explore the possible purchase of 2 to 5 percent of the new reactors. The letter of intent does not bind the Columbus, Ohio-based company to a purchase.

Earlier this month, the Berkeley County-based utility said it had signed another letter of intent that allows it to negotiate a deal with South Mississippi Electric Power Association to buy 2 percent to 7 percent of the $10 billion project as well as some of the energy it generates.

Santee Cooper owns 45 percent of the V.C. Summer nuclear power plant expansion. Cayce-based South Carolina Electric & Gas Co. owns 55 percent of the two 1,100-megawatt units being built in Fairfield County north of Columbia. The Nuclear Regulatory Commission approved licenses for the project in March.
