When it is exactly at its lowest point; the point where it is closest to the ground. Before that point it is accelerating; after that point it is decelerating.
At the bottom of it's swing. This is because it has accelerated to it's peak velocity due to gravity.
At the bottom of its swing in the center, the pendulum has maximum kinetic energy (KE) and no potential energy (PE) because it is moving its fastest and is at its lowest point.
The kinetic energy is greater at the bottom of the swing because the pendulum is moving fastest at that point. As the pendulum swings down, the potential energy is converted into kinetic energy, resulting in increased speed at the bottom.
This could be quantified using calculus, but to simply know WHERE it is fastest but not how fast, simple first principals are all that is required - that of conservation of energy. At the low point the pendulum has it's least Potential Energy (PE) - it has fallen as far as it can. As it rises it gains PE, gathering that energy by reducing the Kinetic Energy (energy of motion) of the mass. Clearly the pendulum is traveling fastest at the bottom.
The factors that affect the period of a pendulum with a horizontal moving support include the length of the pendulum, the amplitude of its swing, the acceleration due to gravity, and the velocity of the support.
A swinging pendulum is moving fastest at the lowest point of its arc. That is the point where all its potential energy has been converted into kinetic energy, and it is the only point in a pendulum's arc where that happens. See related link (a simulation).

A pendulum is fastest at the lowest point of its swing, where its kinetic energy is maximum. At this point, all the potential energy has been converted into kinetic energy, resulting in the highest speed of the pendulum.
A complete swing of a pendulum is called an oscillation or a cycle. It consists of the pendulum moving from one side to the other and back again.
At the highest point of the swing, the pendulum has maximum potential energy since it is at its highest position. The pendulum has maximum kinetic energy at the lowest point of the swing since it is moving with the highest velocity at this point.
