BOSTON (AP) -- Natural gas utility NStar says its customers can expect to pay an average of $4 less per month if a proposed rate cut is approved.

NStar has proposed cutting its supply price by nearly 27%, or about $0.39 per therm, down from the current price of nearly $0.53. If approved by the Massachusetts Department of Public Utilities, the price cut will save the average gas customer $4 a month beginning Sept. 1.

The proposed decrease reflects a drop in prices on the New York Mercantile Exchange.

NStar has about 300,000 natural gas customers in Massachusetts.
