the base
It can supply 2.5 kW to a load with a power factor of 1. Otherwise the power available must be multiplied by the power factor which is always less than 1. If uncertain assume 0.8 which makes it 2 kW.
Power factor improvement means the power factor has been made closer to 1. If a power station delivers energy to places where the load is significantly reactive (contains capacitative or inductive components) it is expensive for them because they deliver current which actually doesn't do any work. The cosine of the phase angle between voltage and current is the power factor.
If it's a simple resistive circuit, or a D.C. circuit, 1 kVA = 1 kW. Generally, it depends on your power factor. Since real power, P, is equal to the total power, S, multiplied by the power factor, p.f. Power factor is the cosine of the angle between the current and the voltage, O. So, P = S * cos(O)
Rated power factor
In mathematics, the term "power" refers to the number of times a base number is multiplied by itself. For example, in the expression 2^3, the base is 2 and the power is 3, indicating that 2 is multiplied by itself 3 times. Powers are also known as exponents and are used to represent repeated multiplication in a concise manner.
the base
The base is the common factor multiplied repeatedly by the exponent.
The index or the exponent - but only if it is a non-negative integer.
The power or exponent.

12 to the power of 10 is 12 multiplied by itself ten times.
It is called the base.
3 * x * x * x * x
A product.
The current's power factor is the true power divided by the apparent power. The Apparent Power is the volts multiplied by the amps. In this example, the ratio would be 200/253, or approximately .79.
