$2.5 million annually

Project overview

The Cogenex division of Alliant Energy Integrated Services signed a master energy services agreement with DuPont Canada in December 1999. First steps included energy audits of DuPont's manufacturing sites, beginning with a pilot project in Ajax, Ontario.

The project focus then expanded to Dupont's largest sites in Kingston and Maitland, Ontario. These facilities account for about 90 percent of the company's manufacturing energy consumption.

Project details

DuPont Maitland:

• Alliant Energy Integrated Services - Cogenex investment of $15 million in new process technology at the plant
• Goal to reduce amount of steam energy needed by 30 to 60 percent
• New system commissioned in 2001

DuPont Kingston:

• Five projects - total investment of $9.1 million
• Installation of small commercial boilers to provide heat for office building (replacing decaying underground steam pipe)
• Lighting retrofit
• Installation of new condensing economizer on main steam boilers to recover heat from flue gases
• Installation of closed circuit glycol loop to recover process heat and use for space heating in winter
• Develop process to recover/recycle waste vegetable oils (previously incinerated)

Annual energy usage saved

Energy savings from the Maitland and Kingston projects are expected to be equivalent to six to eight percent of total energy consumption across the company.

This provides a major contribution to DuPont Canada's goal of reducing per-unit energy consumption by 15 percent between 1995 and 2005.
