Platform tower assemblies for mounting wind turbine assemblies, as well as methods, systems and components related thereto. A central shaft may support a series of planar platforms along its length, each platform constructed to support a plurality of wind turbine assemblies. The wind turbine assemblies may be positioned to optimize production based on prevailing wind directions, and may include turbine assemblies optimized for different wind conditions. The platform tower may include a housing around a lower portion for storage of batteries and control circuitry. The uppermost platform may include one or more solar panels for additional power generation capability.
