Mirant (Southern Energy) to Buy Jamaican Power Utility

LCG, Feb. 7, 2001Atlanta-based Mirant, the former Southern Energy Inc. and still a subsidiary of The Southern Co., will pay the Jamaican government $201 million for an 80 percent interest in Jamaica Public Service Co., the country's principal electric utility.

Mirant will place six directors on the company's nine-member board. The Jamaican government will retain a 20 percent stake in the firm and be represented on the board by three directors.

Prime Minister P. J. Patterson told the Jamaican parliament yesterday that Mirant was selected over two other U.S. bidders, Duke Energy Corp. and Reliant Energy Inc. "Only Southern indicated a willingness to acquire the Company as an integrated operation transmission, distribution and generation," Patterson said, adding that Duke and Reliant were interested only in the company's generation operations.

Patterson said the power situation in California spurred negotiations, calling the Golden State's problems "a real wake-up call for the rest of the world and a clear indication of where Jamaica could head if we fail to put JPS on a stable and financially sound footing."

The prime minister said Southern planned to invest an additional $500 million in JPS, mostly in new generation, over the next 10 years. The sale is expected to close by the end of next month, he added.
