There is some benefit to having a single large scale power plant vs many small engines/generators - a large turbine that runs relatively constantly can be made far more efficient than a smaller diesel generator that spins up and down regularly. It also allows electrification of down the line outputs, which instantly get the benefit from replacing the coal plant with something more efficient when German lawmakers finally wake up and get their act together.
