Situation You are the manager of a large warehouse that is required to be operational 24 hours a day. The electrical distribution system for the warehouse supplies power to various electrical loads such as lighting, heating, air conditioning, various motors, and miscellaneous office components. Your monthly electrical costs are calculated based on the apparent power your warehouse is consuming. Corporate management has directed you to reduce your total power consumption by 15-20% while still maintaining the warehouse operational 24 hours a day.
Assume all non-essential electrical loads have been secured and the remaining electrical loads are required to be operating 24 hours a day. What are some of the measures you can take to reduce the overall warehouse power consumption?
