The US Department of Energy (DOE) recognized Cummins for reducing energy use and costs at its Jamestown Engine Plant in New York. Through the Better Buildings, Better Plants Challenge, Cummins committed to a 25 percent reduction in energy intensity by 2016 across 104 facilities, including 19 plants covering more than eight million square feet. Cummins has already achieved its goal with a cumulative energy intensity reduction of 34 percent, and the company’s efforts in Jamestown are expected to reduce the plant’s energy intensity by a third, resulting in energy savings of about 250 billion BTUs and saving the company nearly $1.4 million in energy bills.
The Jamestown Engine Plant has been undergoing its largest infrastructure upgrade in more than 40 years. Critical equipment has been updated, leading to increased energy efficiency, greater reliability and grater operational stability. The company proceeded with a phased, whole-building energy and infrastructure improvement project—setting aside $5.1 million specifically for energy efficiency projects.
As a part of this approach, Cummins installed energy efficient lighting and a new thermal insulated roof with solar panels and upgraded the heating and cooling system and the energy control system. The new 2-MW solar installation is capable of generating about a third of the plant’s power on the sunniest days, and the company is replacing almost all of the steam used at the plant with direct-fired gas units and new cooling equipment. The plant has installed three regenerative dynamometers that recover energy from engine testing and provide power to the facility. Other improvements and upgrades make the plant the first Cummins site to achieve zero-waste-to-landfill status.
