Each power cycle, you give a big push on a rod of power to the grid. When we have perfect power factor, the grid simply takes it all perfectly – you have a constant resistance on the ride you’re pushing.
When power factor is off, you give a push, but at first the resistance is very low, so the rod goes forward really far and takes a lot of energy from you. But later in the cycle, the grid actually starts pushing it back.
Essentially it’s a short-term load of energy you give to the grid each cycle. The grid ultimately pays it back, but the transmission lines always take a commission on each transaction.
