We’re a metal stamping shop with running presses, welders, and air compressors. Our electric bills nearly double from June through August last year. We’ve already installed LEDs and upgraded some motors, but I feel like we’re still missing something big.
What systems should we look at first for low-hanging fruit in an older facility?
Thanks for the question, John. In older stamping facilities, compressed air could be a hidden energy drain, especially with leaks, over-pressurization, and oversized compressors. HVAC and ventilation loads also spike during summer, especially if process heat from welders or presses isn’t well managed. Also consider reviewing your electricity tariff: the increases might be due. For example, to peak demand charges from running multiple machines at once. Performing an energy assessment would be a great next step. Your regional ITAC can provide you with a no-cost energy assessment for your facility . You can find your local ITAC in this link .
Got it, compressed air and demand charges both sound like things we need to look into. We’re based in Toledo, Ohio, is there a specific ITAC that covers our area? And what’s the best way to get started with the assessment process?
