Pennichuck Corporation Announces New Hampshire PUC Approval
of 31.43 Percent Final Rate Increase
Replaces 14.41 Percent Temporary Rate Increase In Effect Since July 2006

MERRIMACK, NH (May 29, 2007) - Pennichuck Corporation today announced that on May 25, 2007, the New Hampshire Public Utilities Commission (the "NHPUC") issued an Order approving the rate settlement in effect between the Company's Pennichuck Water Works, Inc. subsidiary ("Pennichuck Water"), the staff of the NHPUC, and the New Hampshire Office of Consumer Advocate. The Order makes effective an annualized increase in Pennichuck Water's revenues of approximately $5.2 million, or 31.43%, and replaces an annualized temporary increase of $2.4 million, or 14.41%, that has been in effect since July 2006.

The primary purpose of this rate relief is to allow Pennichuck Water to recover a portion of its costs incurred to upgrade its water treatment plant to meet more stringent federally mandated water quality standards. Pennichuck Water initiated the rate relief proceeding in June 2006 when it requested an overall increase in its rates that would have resulted in an annualized increase in revenues of approximately $6.1 million, or 36.49%. At that time, Pennichuck Water proposed that the rate relief be considered in two parts - an initial increase of 15.91% and a step increase of 20.58%. In September 2006, the NHPUC approved a temporary increase of 14.41% for service rendered on and after July 18, 2006. The final Order now being announced includes a permanent increase of 11.07% for service rendered on and after July 18, 2006, plus a step increase of 20.36% for service rendered on and after January 5, 2007. The net amount due to Pennichuck Water from periods predating the NHPUC Order, including approved rate case expenses, will be billed to customers in equal installments over a nine-month period.
