Since the reduction in electrical load is found to be 1)7 MW by using TES, there will be a saving of SR 1 700 000 for the new power connection. The reduction in building electric load will certainly reduce the transformer size by 1)7 MW. 3.
READ MORESometimes called "load shedding," peak shaving is a strategy for avoiding peak demand charges by quickly reducing power consumption during a demand interval. In some cases, peak shaving can be accomplished by switching off equipment with a high energy draw, but it can also be done by utilizing separate power generation equipment, such as on
