Reducing reactive power by improving the power factor of an AC load helps to minimize the overall cost of running inductive loads. Capacitors are commonly used in industries to improve the power factor and minimize energy wastage.
How reactive power is helpful to maintain a system healthy
Rather than using conventional capacitors and inductors combined with fast switches, however, the STATCOM uses power electronics to synthesize the reactive power output. Consequently, output capability is generally symmetric, providing as much capability for production as absorption.
motor
Now, capacitors are used to help generate this reactive power, (as they dissipate power when the inductor consumes it) and are hence placed near the load to reduce the reactive power that needs to be transmitted.

Synchronous condenser
The reactive power produced by a capacitor bank is in direct proportion to the square of its terminal voltage, and if the system voltage decreases, the capacitors produce less reactive power, when it is most needed, [2] while if the system voltage increases the capacitors produce more reactive power, which exacerbates the problem. In contrast ...

What does the value of reactive power represent physically?
Since reactive power is only concerned with the current component along the 90 deg axis, capacitors and inductors will "produce" opposite polarities of reactive power. By convention, capacitors "generate" positive reactive power and inductors negative. That''s another way of saying inductors are reactive power loads.
