The present disclosure relates to a method for constructing a penstock. A path of the penstock to be dug along a central axis of a hydro-electric site within a rock mass is planned. A lower shaft is excavated, the lower shaft intersecting the path of the penstock. A starting station extending from the lower shaft and from a bottom of the path of the penstock is excavated. The penstock is excavated. An arrival station is excavated and is overhanging above a top of the penstock. An expansion chamber broadening a width of the penstock and broadening a width of the lower shaft near the bottom of the path of the penstock is excavated. A hydro-electric site comprising the penstock is also disclosed.
