New Hampshire Electric Rates Hinge on PSNH Bonds

LCG, March 22, 2001If Public Service Co. of New Hampshire is unable to market between $500 million and $550 million in securitized debt by the end of this month, its electric rates will automatically increased by 5 percent on April 1.

The bond issue is one of three securitized debt issues PSNH and other Northeast Utilities subsidiaries plan to issue over the next month and a half, raising a total of around $2.1 billion. As of Tuesday, PSNH said credit ratings on its issue would not be available in time for a sale this month.

Gary Long, president of PSNH, told the New Hampshire legislature that its bond issue would probably be delayed until mid-April. He pointed out that this would allow a 10 percent rate decrease on May 1, adding that if the 5 percent increase took effect on April 1 the total reduction on May 1 would be 15 percent.
