NTPC and the Government of the NWT have invested in a football-field-sized solar energy project in Fort Simpson, the largest solar powered system in northern Canada. The solar system can generate 100 kilowatts on bright days, enough to power about 17 houses. Solar power supplements the community's diesel operations, and reduces greenhouse gases by about 76 tonnes over a year.
The 436 panel solar array is 91 metres long and 4.2 metres wide and stands about 3 metres off the ground (about the height of a one-storey building). More than 90% of the $1.07M project cost was funded by the GNWT (Departments of Environment and Natural Resources and Industry, Tourism and Investment); the balance of the project was funded by NTPC.
