Generator Air Cooler (GAC) is an important part of the hydropower system which is used to cool the air in the generator room. GAC is a form of application of a heat exchanger (heat exchanger) with water as a coolant. There is a difference in air temperature before and after the GAC, so presumably it can be utilized by using a thermoelectric which is expected to work well as a coolant, in this case it takes into account its ability to absorb heat as a thermoelectric input and generate electrical energy as its output. From the test results, the addition of a thermoelectric was able to increase the effectiveness and NTU and also reduce LMTD. The effectiveness of the resulting GAC without thermoelectric addition yielded 89.90%, 91.85%, and 91.51%. Meanwhile, if the thermoelectric is added, it is 91.39%, 92.82%, and 92.58%. The electric power generated from three days of thermoelectric testing was 0.022W, 0.019W, and 0.021W, with an efficiency of 6.44%, 5.18%, and 4.07%.
