Rate decreases approved for 2011-12 heating season for customers NW Natural received approval to pass on more than 2 percent rate decreases to residential customers in Oregon and Washington, effective Nov. 1, 2011. These rate reductions result in the lowest billing rates in seven years for the company’s residential customers. Rates are established each year under purchased gas adjustment (PGA) mechanisms in Oregon and Washington to reflect the expected cost of natural gas commodity purchases, which includes the company’s cost of gas in inventory and its gas purchases hedged with financial derivatives. The company updated its PGA prices for Oregon and Washington customers in mid-October, and the new rates went into effect Nov. 1, 2011. Under the company’s PGA incentive sharing mechanism in Oregon, the company also selected a 90:10 sharing ratio for customers and shareholders related to commodity gains or losses in Oregon for the 2011-12 heating season. In Washington, all gas costs are passed through to customers.
