Identify where energy waste is occurring; quantify how much and how expensive.
Energy management is a business decision. Reducing energy expenditure makes sense if there is enough ROI and if the activity involved with detecting and addressing energy waste aligns with, instead of detracting from, priority operations. Power quality is key. Most industrial facilities are wasting energy in places that do make sense to address, but you can't make meaningful decisions off of a monthly all-up electrical utility statement. Take a divide-and-conquer approach. Assess your system's reliability for possible failures and against likely waste. Then pick the best candidates for biggest energy waste ROI. Next, log energy consumption over time at individual systems or equipment and inspect for various symptoms of waste. The mantra is to identify and quantify. Identify where energy waste is occurring; quantify how much and how expensive.
