Embodiments of the invention provide systems and methods for generating and delivering electricity and/or hot water for combined heat and power (CHP) using one or more fuels. In many embodiments, the system can be used to provide efficient electrical, heating and cooling utilities to a residential household or group of households. Embodiments of the system can be configured for specific heat flow, while minimizing losses and maximizing total system efficiency. Embodiments also provide for stackable energy generation modules allowing the system to be placed in or nearby a residence to provide power to the residence. Embodiments also provide a control system which can be configured to monitor household electrical usage and dynamically regulate the system to operate at maximum efficiency as well as sell power to an external grid.
