NW Natural, formerly Northwest Natural Gas Company, is a publicly traded utility headquartered in Portland, Oregon, United States. Primarily a natural gas distributor, the company services residential, commercial, and industrial customers in Western Oregon and Southwest Washington in the Pacific Northwest. Founded in 1859, the company has approximately 680,000 customers and revenues of nearly one billion in US dollars annually.
Portland Gas Light Company began as the first gas company in the Pacific Northwest in 1859, based on a perpetual charter by the territorial government. The territorial government granted the charter in January 1859, only a month before Oregon became a state on February 14, at which time the Oregon Constitution became effective. The Constitution would not have allowed this perpetual franchise had the Constitution been in effect at the time the charter was granted. The company was started by H.C. Leonard and Henry D. Green, "colorful pioneers" who knew each other in New York, met again in San Francisco, and started a general store in Astoria in 1850.
Moving to Portland in 1852, Green and Leonard built the first shipping dock in Portland. They also operated as agents for Pacific Mail Steamship Company and exported goods to the Hawaiian Islands and Asia. Their first coal gasification plant at Flanders and the waterfront operated on coal from Vancouver Island. Gas began flowing in 1859, and the first gas lights were in a section of downtown Portland beginning June 1, 1860 and supplied 49 customers. They incorporated as the Portland Gas Light Company in 1862 and purchased the Portland Water Company franchise. They also created the East Portland Gas Light Company in 1882, creating a plant at East Second and Ankeny.
Green died in 1885, and Leonard sold the Portland Water Company franchise to the city in December 1886. The gas business was sold to bankers C.F. Adams and Abbot Low Mills in August 1892 for a reported $850,000. Adams and Mills reincorporated as the Portland Gas Company and bought three other franchises, including the East Portland Gas Light Company. They connected east and west Portland with a 10-inch gas main under the Willamette and then dismantled the eastern gas plant.
In 1913, the company was sold to the American Power & Light Company for $3.5 million and was renamed the Portland Gas and Coke Company. American Power was a subsidiary of the Electric Bond and Share Company of New York (EBASCO). EBASCO was the holding company for small utilities owned by General Electric. Using American Power's financing, Portland Gas supported the creation of St. Johns Gas Company in 1909, Clackamas County Gas Company in 1913, and acquired both companies in 1915.
In the early days of the company, gas was manufactured from coal or oil in local plants. This process ended with the arrival of natural gas to the region in the 1950s, and the company closed its last gas plant in 1957.
In 1958, the company changed its name to Northwest Natural Gas Company. During the 1960s, 70s, and 80s, the company continued to grow and expand its service area beyond Portland and the Willamette Valley. By the end of 1989, the company had grown to serve over 300,000 residential customers. The company’s name was changed again, from Northwest Natural Gas Company to NW Natural in 1997.
NW Natural moved from the NASDAQ stock market to a listing on the New York Stock Exchange under the symbol NWN in 2000. NW Natural attempted to purchase Portland General Electric, a Portland based electricity utility, for nearly $3 billion beginning in October 2001 from Enron. Due to issues including the bankruptcy of PGE parent Enron, the proposed merger was abandoned in May 2002. For a fifth straight year Business Ethics magazine named NW Natural to its list of 100 Best Corporate Citizens, ranking 47th.
In 2005, the company began removing tar from the site of a former plant that had polluted the Willamette River and were later fined for actions related to that clean-up. In 2007, NW Natural announced plans to construct a new pipeline for delivery of natural gas, and announced a rate cut for the first time in six years.
NW Natural is Oregon’s largest natural gas utility. It serves customers along the Oregon Coast, in the Willamette Valley, the Columbia River Gorge, and the Portland metropolitan area. The company operates an underground natural gas storage facility near Mist, Oregon, in the Northern Oregon Coast Range utilizing depleted gas wells, as well as a facility near Fresno, California. These former wells allow the company to purchase the gas when prices are lower and store until needed during peak consumption times during the winter.
