Electricity bought to compress air that never does work
Specific power is measured at the working discharge pressure — every extra bar costs roughly 7% more energy for the same flow, so reducing system pressure and fixing leaks are the same project. A shed with no leak survey typically leaks 20% or more of its generated air.
