Re: Northern Utilities, Inc., New Hampshire Division - Docket DG 06-129 - March 2007 Monthly Cost of Gas Report

Dear Ms. Howland:

Pursuant to the Commission's Order No. 24,684 in Docket DG 06-129, enclosed are an original and one copy of Northern Utilities-New Hampshire Division's current calculation of its projected over or under collection of gas costs ending April 30,2007 for the 2006-2007 winter period. The Company is also providing reports updated through . --_ February 2007 of Northern's: (a) monthly number of transportation service customers and associated gas usage, (b) summary of its hedging transactions and (c) monthly inventory interest calculation.

The calculation, which reflects the gas futures prices of March 20,2007 and actual gas costs through February 2007, indicates an anticipated under recovery as of April 30,2007 of $1,188,250 or 3.16% of the total anticipated gas costs for the winter 2006-2007 period. Northern is not proposing a rate change

Very truly yours,

QnaliED. Gibbons

Manager of Regulatory Accounting
