Abstract: A method of operating a power generator comprises receiving, a fault code corresponding to an operating condition of the power generator being outside of an acceptable range. A generator controller determines a cost of increased maintenance or repairing damage associated with overriding the fault code and maintaining existing power output from the power generator through the operating condition. A cost of a utility fine or contractual penalty associated with shutting down the power generator is determined in response to the fault code. The generator controller compares the cost of the utility fine or contractual penalty associated with shutting down the power generator with the cost of increased maintenance or damage repair to the power generator associated with overriding the fault code and maintaining existing power output through the operating condition. In response to the comparing, the fault code is overridden continuing operation of the power generator.
