This could be considered a bug, because technically the chunks are not supposed to be loaded. It reloads the chunks every update because it's all connected to the same  network. As the Quarry requests power, all the chunks are loaded that contain a pipe carrying power for the request. If there is a cable for your machines in the same chunk as the power-carrying pipes, the cables will also draw power. So, basically, make sure none of your cables are in the same chunk as your pipes (A surefire way of accomplishing this is to have at least a 15-block gap between the two).
