On-site energy with staying power CITIZENSHIP

A long-term commitment to reduce our environmental impact.

ON-SITE ENERGY PRODUCTION YIELDS BIG SAVINGS

At Medtronic, producing our own energy is part of a long-term commitment to reduce the environmental impact of our operations.

In fiscal year 2018, Medtronic on-site production totaled 69,100 MWh — enough to power more than 6,400 U.S. homes for an entire year. The low-carbon energy generated at Medtronic facilities in California, Connecticut, Ireland, and Italy covered eight percent of the company’s total energy use.

“We invest in on-site energy generation, specifically cogeneration and fuel cell technologies, because it provides great environmental and financial returns,” says Daniel Sterner, global director, energy and utilities infrastructure at Medtronic.

Cogeneration is a process that captures leftover heat from on-site power systems and puts that energy back into production. Fuel cells produce electricity through an electrochemical reaction that uses a fuel source which, in our case, is natural gas. Respectively, cogeneration and fuel cells can be 75% and 56% more energy-efficient than traditional power sources. Additionally, the systems don’t take up much space but they produce a lot of energy.


MORE THAN $2 MILLION IN ANNUAL ENERGY SAVINGS

North Haven cogeneration system

Chris Sirois, divisional facilities director at Medtronic and Steve Bartlett, director of engineering and operations excellence, manage on-site energy generation at a Medtronic cogeneration plant in North Haven, CT. The site, built in 2009, produces 43,000 MWh of energy as well as two fuel cells, installed in 2018, which generate a combined 4,300 MWh of energy per year. The new fuel cells will power 100% of the North Haven offices and 30% of the manufacturing facility.

This year, Medtronic invested $1 million to refurbish the existing North Haven cogeneration system, which reduced the site’s greenhouse gas emissions by over 40%.

“The decision to refurbish the system was an easy one. The reliability of cogeneration systems has significantly improved since 2009 when the system was first installed. Our project will drive more than $2 million in energy savings annually, making it well worth the effort,” says Chris.
