In accordance with some embodiments, the present disclosure is directed to systems having a fuel cell and a turbine generator, each capable of providing electrical power to a utility grid, and methods for operating the same. The system may have a main AC bus which is coupleable to the utility grid. The fuel cell may be coupled to main AC bus through an inverter. The turbine generator may be coupled to the main AC bus through a series of inverters, one of which may include the inverter by which the fuel cell is connected to the main AC bus. One or more load banks may be provided to provide a load for electrical power generated from the fuel cell, turbine generator, or both in case the system is disconnected from the utility grid. Further support and backup systems may be provided.
