Washington Utilities and Transportation Commission
The commission reviews the Federal Energy Regulatory Commission (FERC) Form 2: Annual Report of Major Gas Utilities and other documents provided by regulated natural gas utility companies operating in Washington as part of its regulatory activities. The commission publishes relevant information on the financial and physical operations of regulated utilities. This report presents the annual statistics of Washington's four natural gas utilities for the years from 1998 through 2016.
The four natural gas utilities that operate in Washington are:
Cascade Natural Gas Corporation
Northwest Natural Gas Company
Puget Sound Energy
As shown in the table below, only Puget Sound Energy operates entirely within Washington State. Northwest Natural Gas operates primarily in Oregon State. Cascade Natural Gas operates primarily inside Washington State.
For more information on interpreting this data, see below.
Puget Sound Power & Light Company and Washington Natural Gas Company merged to form Puget Sound Energy in February 1997. Puget Sound Energy now operates as a combined gas and electric company in Washington State.
In 1991, Washington Water Power Company acquired CP National to add gas properties and customers in Oregon and California. In addition to this acquisition, effective January 1, 1999, Washington Water Power changed its corporate name to Avista Corporation, d.b.a. Avista Utilities.
Commission staff presents information in graphs that either combine data from all companies or compare data between companies. The graphs cover a 15 year period while the tables in this report present only the past ten years due to the limited space on each page for data presentation. The first five years source information for the graphs may be found in previous editions of the Annual Statistics Report.
The Summary Table illustrates the revenues and expenditures, net income, therms delivered, and customer information for the four companies total natural gas operations in Washington State. The sources of gas revenues indicate that the residential market accounted for 62.22 percent of natural gas revenues in Washington State. The second largest market is the commercial market which accounted for 27.26 percent. The remaining 10.52 percent is industrial, transportation, and other revenue. Graph I on page 5 illustrates the four major market sectors for natural gas revenue generated in Washington State.
Each gas company submits an annual report to the Commission. These reports contain schedules following the uniform system of accounts designated by the Code of Federal Regulations (CFR). For this report, the commission staff has arranged the information for each company into the following tables:
Time series financial and operational data are presented as tabs in this report for each of the four natural gas utilities. There are twelve tables for each company except Puget Sound Energy. Nine of the twelve tables are "Total Company Operations" and labeled as Tables 1 through 9 in the upper left hand corner. Three are "Washington Operations Only " and labeled as Table 6ST, 8ST and 9ST. Since Puget Sound Energy operates only within Washington State, the "Total Company Operations" and "Washington Operations Only" are identical. There are no Tables 6ST, 8ST and 9ST for Puget Sound Energy.
Each Table is labeled for ease of use and comparison as follows:
As in any attempt to develop continuous and comparable time series data, one of the main problems is to assure comparability of various data elements. Though comparability is assured at broad group levels, the individual data elements that are added pose a continuous problem for comparison over time due to changes in accounting systems. For instance, beginning with the 1990 report on tables 6 and 9 for each company the revenues from transporting the gas of others are itemized. Although this became a growing portion of company income in 1986, only data from 1989 forward is compiled. These problems are under continuous investigation and changes and improvements are incorporated as they become appropriate.
