Abstract
The Bonneville Power Administration(BPA)was created in 1937 to market power from Bonneville Dam and later, Grand Coulee Dam, two New Deal relief projects on the Columbia River. Between 1939 and 1945 the BPA built a long-distance, high-voltage electrical transmission network that connected Bonneville and Grand Coulee Dams with population centers in Oregon's Willamette Valley and Washington State's Puget Sound area. Known as the "master grid," the original transmission system included 2,736 circuit miles of transmission line and fifty-five electrical substations. This study provides a historic context for the properties that comprise the master grid. It also identifies and describes the grid's two main property types: the electrical substation and the transmission line, discussing ranges of variation and distribution patterns for each type. This study also sets forth registration requirements and evaluation criteria for the master grid properties, as well as treatment recommendations and mitigation measures for their preservation.
