'''Manic-1''' is a [[hydroelectricity|hydroelectric]] [[power station]] and [[dam]] at the mouth of the [[Manicouagan River]] {{convert|3|km|mi|1|abbr=on}} west of [[Baie-Comeau]], [[Quebec]], Canada. The power station was commissioned between 1966 and 1967 and producing 184 MW, it is the smallest of the Manicouagan-Outardes project.<ref>{{cite web|title=Hydroelectric Plants in Quebec|url=http://www.industcards.com/hydro-canada-qc-l-s.htm|publisher=Power Plants Around The World|accessdate=3 June 2013}}</ref><ref>{{cite web|title=Hydroelectric Generating Stations|url=http://www.hydroquebec.com/generation/centrale-hydroelectrique.html|publisher=HydroQuebec|accessdate=20 August 2010}}</ref>
==History==
Between 1949 and 1956, to keep up with increasing electricity demands, the Manicouagan Power Company constructed and upgraded a 126 MW hydroelectric power station on the falls of the Manicouagan River' mouth. Electricity demand continued to rise with the construction of local [[grain elevator]]s and an [[aluminum smelter]]. This power station was further supported and regulated by the [[McCormick Dam]] on St. Anne lake which [[Hydro-Québec]] had completed by 1959. However, as plans for the Manicouagan-Outardes project progressed, engineers discovered that water flow at the mouth of the Manicouagan could be better utilized. At Hydro-Québec's request, the Manicouagan Power Company further upgraded the McCormick plant's capacity to 190 MW. Additionally, Hydro-Québec decided to build the Manic-1 generating station adjacent to and augmenting the existing plant and dam.<ref name="Paradis1967p31">{{harvnb|Paradis|1967|pp=31–34}}</ref>
==Characteristics==
The Manic-1 Dam consists of a concrete center portion that houses the power station and two rock-fill [[levee|dike]]s on either side. The western dike is {{Convert|280|ft|m|abbr=on}} long while the eastern dike that connects to the McCormick Dam is {{Convert|370|ft|m|abbr=on}} long. The [[Tailrace#Headrace.2C tailrace|tailrace]] or downstream portion of the dam is a {{Convert|2000|ft|m|abbr=on}} long, {{Convert|72|ft|m|abbr=on}} wide and {{Convert|280|ft|m|abbr=on}} deep trench that was dug during construction. The power station's [[hydraulic head]] is {{Convert|120|ft|m|abbr=on}} but can vary between {{Convert|113|ft|m|abbr=on}} and {{Convert|128|ft|m|abbr=on}} because of sea [[tide]]s.<ref name="Paradis1967p34">{{harvnb|Paradis|1967|p=34}}</ref>
At the time of the plant's commission, Manic-1 was expected to operate as a [[peaking power plant|peaker plant]],<ref name="Paradis1967p53">{{harvnb|Paradis|1967|p=53}}</ref> generally run only at times of high demand for electricity, known as [[peak demand]]. It was expected to generate 40 gigawatt-hours annually.<ref name="Paradis1967p53"/>
