The first two space elevators were built on Ceres for the construction of the colonies, and they are two of the few in the solar system. (All space elevators are built on asteroids because of its low gravity, which is much more easier then on Earth.
There is an Integrated Concentrator SSPS on the top of orbit station, which provides power for itself or reflect the light to the colonies from ring belt reflectors.
