Site C dam
The Site C dam (or "Site C Clean Energy Project") is a $8.3 billion project by BC Hydro for a large-scale earth fill hydroelectric dam on the Peace River in north-eastern British Columbia, Canada.〔(【引用サイトリンク】title=Backgrounder: About Site C ) 〕 The site is downstream from the existing W.A.C. Bennett and Peace Canyon dams. Designs call for an estimated capacity of approximately 1,100 MW and an annual output of 5,100 GWh of electricity. This will be the first large dam built in BC since 1984 and BC's fourth largest producer of electricity.
==History==
If built, it would be the third of four major dams on the Peace River that were initially proposed in the mid-twentieth century. The first project is the flagship W. A. C. Bennett Dam 19 kilometres west of Hudson's Hope. Site C would flood 83 km of the Peace River, widening it by up to 3 times, as well as 10 km of the Moberly and 14 km of the Halfway Rivers. Over 57,000 acres of agricultural and forested land would be impacted by Site C, including 31,528 acres of Class 1-7 agricultural land and over 17,000 acres of forested land. The Bennett Dam was completed in 1967 and began operation in 1968. Construction of the Peace Canyon Dam was completed in 1980 at a point 23 km downstream of the W. A. C. Bennett dam. The third dam – "Site C" – was also proposed at the time for a site 83 km downriver of the Peace Canyon dam, or approximately 7 km southwest of Fort St. John. The initial proposal was never completed, however it was turned down after BC Utilities Commission hearings in 1983. It has since come under review as BC Hydro reconsiders expansion of its dam capacity on the Peace.〔 The fourth proposed dam on the BC segment of the Peace River, Site E, near the BC/Alberta border was taken off the planning process during the 1982 hearing. A cost estimate produced during the 2007 feasibility study placed the financial cost at a maximum of C$6.6 billion based on the 1981 design, safety, and engineering standards. An updated cost projection was released in May 2011 placing the estimated cost at $7.9 billion.
