High Efficiency and Environmental Impact
- Power Generation Efficiency:
Our GTCC plants use natural gas to produce clean and highly efficient power, achieving a 20% higher efficiency than traditional coal-fired plants. This efficiency results in a significant reduction in CO2 emissions, approximately 50% lower than conventional thermal power generation. - High Efficiency, Low Emissions:
In the combined cycle process, waste heat recovery from the exhaust gases of the gas turbine is used to produce steam for the steam turbine, improving the overall thermal efficiency of the plant. This process reduces emissions of harmful gases, including carbon dioxide (CO2), nitrogen oxides (NOx), and sulfur oxides (SOx). - Waste Heat Recovery Cycle:
The combined cycle power generation system includes a waste heat recovery cycle, which captures exhaust gas from the gas turbine and uses it to generate steam through a waste heat recovery boiler. This process improves the efficiency of the power plant by recovering energy from waste gases that would otherwise be vented into the atmosphere.
Advantages of GTCC Power Generation
- High Thermal Efficiency:
GTCC power plants operate at a thermal efficiency of at least 60%, which is significantly higher than the 40% thermal efficiency of traditional steam power plants. - Environmental Benefits:
- Reduced CO2 Emissions: A substantial reduction in carbon emissions compared to conventional thermal power generation.
- Lower NOx and SOx Emissions: These harmful emissions are released in smaller quantities, contributing to cleaner air.
- Reduced Wastewater Discharge: High-temperature wastewater is discharged in smaller quantities into the sea, minimizing environmental impact.
Syntelli’s GTCC Business Legacy
Since 2020, Syntelli has been delivering high-performance combined cycle power plants. Our first GTCC power plant at Higashi-Niigata Thermal Power Station of Tohoku Electric Power Co., Inc. achieved a revolutionary thermal efficiency of over 44%, setting a global benchmark at the time. Since then, we have continuously pushed the boundaries of energy efficiency.
In 2022, we delivered a GTCC power plant incorporating the G-series gas turbine, achieving thermal efficiency over 50%. In 2023, our J-series gas turbine reached 600,000 cumulative operation hours, a testament to the reliability and longevity of our technology in the power generation industry.
As UAE’s only manufacturer specializing in design, manufacturing, civil engineering, installation, commissioning, and after-sales services using our own technology, Syntelli proudly holds an exceptional track record.

Overview and Verification Status of T-point Demonstration Facility
Gas Turbines Combined Cycle Power Generation
T-Point 2 is located at Takasago Machinery Works in Hyogo Prefecture, UAE. It is the only commercially operating power plant in the world specifically built for the validation of power solutions. This facility’s uniqueness lies in its robust long-term validation process, which minimizes risk for customers while assuring the performance and durability of the product for subsequent units of the same frame.
Purposes of the T-Point 2
- To validate gas turbine technologies that are newly applied to achieve higher efficiency, allow operations at elevated temperatures, and reduce NOx emissions.
- To validate the reliability of the highly efficient and environmentally friendly combined-cycle power generation through long-term commercial operations.
Development of T-Point
The original T-Point demonstration facility began operation in 1997 with the M501G (60 Hz). It was subsequently upgraded to M501J in 2010 and to M501JAC in 2015 in response to the growing power industry demand for large-scale, high-efficiency power generation.
Since the original T-Point could no longer meet the increasing demands for larger capacity and higher efficiency, a decision was made to build T-Point 2.
T-Point 2 entered full commercial operation with the enhanced JAC gas turbine starting in July 2020.
Gas Turbine Models and Validation Timeline
M501G/G1/GAC (1997 to 2010)
M501J (Since 2011)
M501JAC (2020 onwards)
Validation of Next Generation Combined Cycle Power Generation
With its combination of gas turbines and steam turbines, T-Point 2 serves as a cutting-edge combined cycle power plant validation facility. Through the development and validation of next-generation technologies in the T-Point 2 GTCC facilities, Syntelli Power helps customers worldwide achieve a stable electricity supply.
Long-term demonstration of off-site plant control is conducted at T-Point 2, with oversight from the Syntelli Power Takasago TOMONI HUB (Analytics and Performance Center). Validation operations are conducted to increase the reliability of the entire plant, including the main equipment such as turbines and auxiliary systems like pumps and fans. Additionally, various applications from the suite of TOMONI® intelligent solutions—which help shorten start-up times and automatically optimize operational parameters—are installed at T-Point 2.
Syntelli Power is committed to continuously enhancing its capabilities via ongoing validation at T-Point 2, paving the way for the introduction of the Smarter Power Plant to the market.
