The power station was commissioned in 1969 and is run-of-the-river.<ref>{{cite web|title=Hydroelectric Plants in Quebec|url=http://www.industcards.com/hydro-canada-qc.htm|publisher=Power Plants Around The World|accessdate=20 August 2010|url-status=usurped|archiveurl=http://arquivo.pt/wayback/20090719052842/http%3A//www.industcards.com/hydro%2Dcanada%2Dqc.htm|archivedate=19 July 2009}}</ref><ref>{{cite web|title=Hydroelectric Generating Stations|url=http://www.hydroquebec.com/generation/centrale-hydroelectrique.html|publisher=HydroQuebec|accessdate=20 August 2010}}</ref>

Outardes-3 was built in conjunction with the Manicouagan-Outardes project and is located {{convert|13|mi|km|1|abbr=on}} downstream of Outardes-4. Only a {{convert|250|ft|m|1|abbr=on}} high concrete dam was needed to exploit {{convert|478|ft|m|1|abbr=on}} of hydraulic head as the dam raised up water into the existing Lake Tirebouchon. Raising the water in the lake allowed it to rise east near the actual power station {{convert|4.5|mi|km|1|abbr=on}} downstream. Near the eastern portion of the lake, two depressions were filled in with small dikes to withhold the higher lake level, one of which supports a concrete spillway. From the intake on the northern portion of the concrete dam, water is fed via four {{convert|750|ft|m|1|abbr=on}} penstocks towards the underground power station. Water being discharged from the power station enters a {{convert|1488|ft|m|1|abbr=on}} long and {{convert|73|ft|m|1|abbr=on}} high tunnel before being returned to the river.<ref name="Paradis1967p45">{{harvnb|Paradis|1967|pp=45–48}}</ref>
