if load increases, the RPM of the DG set(engine & coupled generator) should maintain constant to make the electric frequency constant. In such a case to balance with the increase in load the engine should have to burn more fuel to maintain the same RPM (energy can nether be created nor be destroyed). Burning of more fuel means more heat produced.
