- Configuration: 2x1 Combined Cycle
- Turbines: 2x GE-6F.03 gas turbines
- Capacity: 275 MW total (65 MW per gas turbine)
- Commissioning Date: February 2020
High-Efficiency Gas Turbine Power Generation
The GE 6F.03 is a highly efficient industrial gas turbine designed for combined cycle applications. It delivers outstanding fuel flexibility and low emissions.
Each GE 6F.03 unit delivers approximately 81 MW at ISO conditions. In a 2x1 combined cycle configuration, total output reaches 275 MW.
The combined cycle process recovers waste heat from both gas turbines via HRSGs to drive a steam turbine, achieving a combined output of 275 MW with significantly higher efficiency than simple cycle operation.
Since commercial operations commenced in February 2020, the plant has maintained high availability and reliability, consistently meeting PT PLN (Persero) power supply obligations under the PPA.
Frequently Asked Questions
A Combined Cycle Gas Turbine (CCGT) is a highly efficient form of power generation that combines gas turbines with a steam turbine. The waste heat from the gas turbines is captured and used to generate steam that drives a steam turbine, producing additional power from the same fuel — significantly improving overall efficiency.
CCGT plants typically achieve thermal efficiencies of 55–60%, compared to around 35–40% for simple cycle gas turbines. This means significantly less fuel is needed per unit of electricity generated, reducing both operational costs and CO₂ emissions.
The plant supplies electricity exclusively to PT PLN (Persero), Indonesia's national electricity company, under a 20-year Power Purchase Agreement (PPA), supporting the Sumatra regional grid.
The plant primarily operates on natural gas, utilizing the GE 6F.03 gas turbines' fuel flexibility to maintain reliable and efficient power generation with low NOx emissions.
