Output of the Siemens Gas Turbine SGT5-8000H*

375MW

Output of 375 MW in simple cycle operation

Siemens developed its new generation H-Class Siemens Gas Turbine (SGT™), the SGT-8000H series, driven by the main goals to reduce emissions and preserve our environment for future generations. The 50 Hz version was built and shipped to be validated at a gas turbine power plant in Irsching, Germany, where it has demonstrated its capabilities under real operating conditions. This innovative gas turbine is characterized by:

efficiency of 40 % in simple cycle operation ■

low life-cycle costs ■

high reliability and availability ■

operational flexibility ■

low emissions. ■

The 60 Hz version, SGT6-8000H, is being completed now its 50 Hz brother is fully validated.

375MW

“In actual operation, the SGT5-8000H has more than met our high expectations: During roughly 1,200 hours of testing in Irsching, Block 4, we were able to experience the performance of the world’s most efficient gas turbine for ourselves. Expansion is currently under way to a combined cycle power plant. With its commissioning in the year 2011, it will similarly set new standards when it comes to efficiency and output.”

Bundled know-how and experience

The new, advanced SGT-8000H series gas turbines and the SCC-8000H series combined cycle power plants feature best-in-class technology derived from our long line of large direct-drive Siemens 50 Hz and 60 Hz heavy-duty gas turbines and power plants. A highly qualified inter-national team of over 250 experienced engineers and over 500 employees worked hand in hand in developing, manufactur-ing and assembling this new gas turbine.

From the customer’s point of view

The advanced technology of the fully air cooled SGT-8000H series gas turbine continues our long-standing tradition of satisfying the needs of our customers all around the world. We take an evolu-tionary approach when designing our new turbines by incorporating proven features based on the experience gained with our reliable operating units over decades. In developing the world’s largest H-Class gas turbine for unmatched com-bined cycle efficiency, we combined the best features of our proven 50 Hz and 60 Hz Siemens heavy-duty gas turbine product lines with new, innovative tech-nological developments.

Proven efficiency and output – proven economic advantagesWith the SGT5-8000H, we are entering a new dimension of sustainable power generation. This gas turbine generates 375 MW in simple cycle operation and 570 MW in combined cycle operation – with an efficiency of over 60 %.

Less complexity for more efficiency

To achieve higher operational flexibility for both the gas turbine and the power plant, the gas turbine features less complex but proven technology, including the use of air cooling over steam cooling for the H-Class. Air cooling as a design strategy makes the SGT-8000H series gas turbines an excellent choice for repowering, as there are no ties to the steam cycle required.

Pioneering solutions for plant technology

The Siemens Combined Cycle single-shaft reference power plant has evolved over the years to be a favorite for combined cycle power plants in the 400 MW Class in the 50 Hz world. The first single-shaft plant with a Siemens F-Class gas turbine was built in 1997. Based on the large fleet of existing F-Class single-shaft power plants and the experience gained from the Irsching 4 project, the new H-Class reference power plant SCC5-8000H 1S was developed.

Well-thought-out concepts

The primary focus of our Reference Power Plant (RPP) program is to develop plant designs that offer high customer benefit through low life-cycle costs. Furthermore, the modular concept used in the RPP program allows easy adapta-tion to specific customer needs and site requirements. The combination of world-class gas and steam turbine and generator technologies with trend- setting power plant system integration results in a highly efficient plant that provides reliable low-cost electricity.

Innovative plant technology that benefits our customersAs the latest addition to our comprehensive gas turbine product line, the new SGT-8000H series, and the Siemens Combined Cycle Power Plant (SCC™), the SCC-8000H series, address the worldwide demand for more environmentally compatible energy. This new gas turbine frame combines the best features of the existing product lines with latest technology advancements.
