8 Efisiensi PLTP keseluruhan Efisiensi keseluruhan diperoleh dari daya yang dibangkitkan dikurangi penggunaan daya pada alat-alat dibandingkan dengan jumlah daya yang masuk dari sumber uap. Dimana : η = W W W W % w turbin = daya yang dibangkitkan oleh turbin (kw); = kw w pompa = daya untuk menggerakkan pompa (kw); = W ph + W pr + W pa + W pv W ph W pr W pa W pv = daya untuk menggerakkan pompa hotwell (90 kw); = daya untuk menggerakkan pompa reinjeksi (11 kw); = daya untuk menggerakkan pompa auxiliary cooling water (1,5 kw); = daya untuk menggerakkan pompa liquid ring vacuum (0,75kW); w kipas = daya untuk menggerakkan motor kipas pada cooling tower ( 2 x 20 kw); W 100% = potensi daya keluaran saat pembangkit bekerja 100% (kw); = h 1 x m = 2760 kj/kg x 8,55 kg/s = kw η = ( ,5 + 0,75) (2x20) = 3.066, = 0,13 = 13 % Efisiensi keseluruhan dari PLTP Kamojang 68 sebesar 13 %. Nilai efisiensi ini berada pada rentang efisiensi PLTP yaitu %. (Moon, 2012)
