An energy recovery system for a power system is disclosed. The power system includes an engine, a generator driven by the engine, an electrical bus configured to receive electrical power from the generator, an exhaust conduit configured to receive exhaust gases from the engine, and a turbocharger coupled to the exhaust conduit. The energy recovery system includes a bypass conduit, a turbo-generator, and a synchronizer. The bypass conduit is coupled to the exhaust conduit, and facilitates a portion of exhaust gases from the exhaust conduit to bypass the turbocharger. The turbo-generator is coupled to the bypass conduit, and is driven by the portion of exhaust gases bypassing the turbocharger. Further, the synchronizer modulates one or more parameters of electrical power received from the turbo-generator based on one or more parameters of electrical power present on the electrical bus. The synchronizer transmits modulated electrical power to the electrical bus.
