Abstract

Pembangkit listrik adalah kumpulan dari beberapa mesin yang sumber utamanya dari listrik tergabung dalam beberapa sistem atau sub sistem untuk menjalankan proses produksi menghasilkan energi listrik. Tidak semua listrik yang di hasilkan dari Generator disalurkan ke pelanggan namun juga ada listrik yang di pakai sendiri untuk menggerakkan motor-motor listrik atau tempat-tempat lain yang memerlukan listrik yang ada di dalam area pembangkit tersebut. Saat ini kebutuhan listrik untuk gedung kantor diambilkan dari unit pembangkit PLTU Amurang sehingga membebani auxiliary power pembangkit tersebut. Perencanaan pembangunan PV sel surya roof top on grid sebagai salah satu alternatif sebagai sumber energi listrik di kantor PLTU Amurang sehingga bisa mengurangi auxiliary power pembangkit utama dan memperbaiki Nett Plant Heat Rate (NPHR). Hasil perhitungan diperlukan 6 modul panel sel surya dengan nominal power per panel 300 Wp dan satu inverter kapasitas 2000 W dengan estimasi biaya Rp 71.500.000,-. Setelah pemasangan PLTS, terdapat perkiraan penghematan rata-rata 133 kWh setiap bulan dan nilai NPHR mengalami penurunan minimal 20,15 kCal/kWh setiap bulannya yang menandakan unit pembangkit utama semakin efisien.
