High Voltage Distribution System Upgrade for Pharmaceutical Company
Energy Industrial High Voltage Distribution System
Sanofi Pasteur (SPL) operates pharmaceutical research and production facilities on a large campus in Toronto.  Recent and future development of the campus requires upgrading of the major utilities, including the high voltage distribution system throughout the site.  We have developed an electrical Master Plan to guide the conversion of the distribution from the current 4.16 kV to 27.6 kV.  Morrison Hershfield was retained by SPL to design and implement both a cogeneration plant expansion and high voltage upgrade.
The expansion of the existing cogeneration plant was designed to accommodate the new 6 MW cogeneration unit, including the building expansion, mechanical systems, controls systems, high voltage and low voltage electrical systems.  The addition of this unit has brought the total generation capacity of the cogeneration plant up to 9 MW.

We designed the upgrade of the existing underground distribution system from 4.16 kV to 27.6 kV. The work includes the upgrade of the main 27.6 kV substation, decommissioning and demolition of the 4.16 kV substation, installation of five 6-way S&C Vista units, and seven outdoor transformers. Provision for a site-wide SCADA system with the installation of an underground fibre-optic loop throughout the campus has also been made.

This cogeneration plant will enable SPL to have a reliable power source and allow the export of power into the open market. The new unit has been tested to a full output of 6 MW.
