Detroit Diesel Corporation operates one facility in Detroit, MI that offers mid-range and heavy-duty diesel engines, e-Powertrains, transmissions, axles, safety systems, and connected vehicle services for on-highway and vocational commercial markets. For the past 10 years, Detroit Diesel has achieved 1-2% of energy reduction annually, with a commitment to build on this trend over the next 10 years. To continue achieving savings, Detroit Diesel signed up with its local utility, Detroit Edison (DTE), to participate in a six-month Strategic Energy Management (SEM) program. Participants received free technical support and financial incentives to implement energy-efficiency improvement opportunities related to steam, HVAC, and compressed air systems. The annual energy cost savings realized in each of the systems were significant in the first year of the SEM program, with $10,000 in steam system savings, over $136,000 in HVAC system savings, and over $76,000 in compressed air energy savings.
