This project focuses on the upgrade and optimization of the high-temperature heating network at the thermal power plant of Cowansville Penitentiary. The work includes the addition of two new boilers, the replacement of existing water-cooled circulation pumps, and the modernization of the fresh air supply systems. In addition to these improvements, control system upgrades aim to fully automate the high-temperature hot water network, supported by electrical work as well as concrete and structural steel interventions.
