Explanation:

kW is the abbreviation for kilowatt. Power is the rate of doing work or transferring energy. The standard unit of power in the International System of Units (SI) is the watt (W), and 1 kilowatt ($1\ \text{kW}$) is equal to $1000\ \text{W}$. Mass is measured in kilograms ($\text{kg}$), time in seconds ($\text{s}$), current in amperes ($\text{A}$), voltage in volts ($\text{V}$), and money has various currency - specific units. Energy is measured in joules ($\text{J}$) (although in some practical contexts like electricity billing, kilowatt - hours ($\text{kW}\cdot\text{h}$) is used for energy, but that is a derived unit of energy, not the base unit).

Answer:

Power
