Utility helps Campbell Company develop on-site co-generation plant
By MRO StaffEngineering Environment Facilities Maintenance Industry Energy Utilities
Capable of producing enough energy to power the facility, the Combined Heat and Power (CHP) project came together as a result of Campbell Canada’s push towards energy efficiency and sustainability, and was made a reality when Toronto Hydro helped arrange incentive funding through the saveONenergy program.
CHP is a technology that uses a natural gas fueled engine to generate electricity and produce heat. The heat produced from the engine generates steam, which is used by Campbell Canada to cook soup. The CHP plant now supplies up to 93% of the company’s annual steam requirements. The power is used entirely within the Campbell Canada facility, displacing electricity which was previously supplied from the electricity grid.
In 2010, Campbell Canada set an aggressive goal to cut its environmental footprint in half by 2020 and the company is well on track thanks to projects like the CHP plant. This project allows Campbell Canada to save on electricity costs, has environmental benefits and provides reliable emergency back up power, ensuring soup production is never impacted.
Toronto Hydro supports CHP as it helps reduce demand on the electricity system at a time when the city is growing at an unprecedented rate.
Campbell has also embarked on other significant energy-efficiency projects, including a $100,000 compressed air upgrade, a major LED lighting retrofit, the introduction of sensors, and more.
•The CHP plant consists of a 4.6MW Combustion Gas Turbine Generator and a Heat Recovery Steam Generator that produces 90,000 lb/hr of steam
•The project took two years to complete
•Campbell Canada’s 60 Birmingham Street location is the company’s only North American site to have this technology
•The CHP project provides 95% of Campbell Canada’s electricity needs, with the remaining coming from the Toronto Hydro grid
•The project is the first to be completed in Toronto using the saveONenergy incentive program
•Toronto Hydro was able to arrange $5 million in incentive funding, which amounted to approximately 40% of the project
What is a Combined Heat and Power plant?
The CHP project at Campbell Canada’s site uses a natural gas turbine to drive a generator, which produces electricity. The hot combustion gas is then delivered to a secondary system which is integral to the CHP plant. Hot exhaust air produced by the turbine is then delivered to a heat recovery steam generator, which uses the heat energy to produce steam at a pressure which is suitable for Campbell Canada’s needs.
The Campbell Canada facility remains connected to Toronto’s electricity grid and Toronto Hydro will continue to supply a small amount of electricity on a daily basis, as well as full power when necessary.
Staying connected to the grid is essential, as it allows Campbell Canada to draw electricity when the CHP turbine is not running; this makes for easy repairs and does not disrupt soup production.
The cost of the CHP project was $12 million. Making the project attractive was $5 million in incentives made possible by Toronto Hydro through the saveONenergy program. Factoring in the incentives, the project had a net cost of $7 million.
