Providing Optimized Economic Performance
For National Economic Development
MENINGKATKAN KETERSEDIAAN, KEANDALAN DAN EFISIENSI PEMBANGKIT
IMPROVING AVAILABILITY, RELIABILITY, AND EFFICIENCY OF PLANT
Efisiensi Thermal (Efisiensi Thermal Netto)
Net Thermal Efficiency
Efisiensi Thermal menunjukkan tingkat energi listrik (output) Thermal efficiency shows the electricity level generated (output)
yang dihasilkan dalam pemakaian bahan bakar (input) during the utilization of fuel (input) on a power plant in a certain
suatu pembangkit pada periode tertentu. Dengan demikian, period. Thus, the higher the Thermal Efficiency rate, the more
semakin tinggi nilai Efisiensi Thermal menunjukkan bahwa efficient the power plant is. Thermal Efficiency for Existing
pembangkit tersebut semakin efisien. Pada tahun 2021, Power Plants in 2021 amounted to 33.55%, decreased by 0.70%
Efisiensi Thermal Pembangkit Eksisting adalah sebesar 33,55% compared to 2020, which was 33.79%. This decrease was mainly
menurun 0,70% dibandingkan tahun 2020 sebesar 33,79%. due to the coal switching program of SPP Suralaya 1-7, which was
Penurunan ini terutama disebabkan oleh program coal switching implemented starting in mid-2020.
PLTU Suralaya 1-7 yang diimplementasikan mulai pertengahan
tahun 2020.
