The Nairn Falls Dam and Generating Plant (or Huronian Power Plant[1]) is a hydroelectric dam and power plant located on the Spanish River to the northeast of the community of Nairn in Nairn and Hyman Township, Ontario, Canada.[2] It is located approximately 50 kilometres west of Sudbury. It is owned and operated by Vale Limited, notable in the area for its mining operations. The power from the plant is primarily supplied to these operations, with excess power sold to Ontario Hydro. The generating plant works in conjunction with High Falls Dams No. 1 and 2, as well as the 'Big Eddy' generating plant, in a cascade system, where excess water power from upstream dams is utilized by the downstream ones.
