The Planck energy divided by the Planck time is the Planck power $P_p $, equal to about $3.62831 \times 10^{52} W$. This is an extremely large unit; even gamma-ray bursts, the most luminous phenomena known, have output on the order of $1 \times 10^{45} W$, less than one ten-millionth of the Planck power.
$P_p = {\frac{ c^5}{G}}$, where $c$ is the speed of light in a vacuum, and $G$ is the gravitational constant.
