Digital Solutions

A world leader in steam turbine manufacturing

For more than a century, we have consolidated the best available technology from numerous steam turbine suppliers into core platforms that support our advanced, innovative, efficient, and reliable steam turbine solutions. GE has highly-qualified and specialized engineering centers and factories in key markets around the world.


  • Industry-leading performance with high reaction 3-D blading designed for high pressure (HP), intermediate pressure (IP), and low pressure (LP) turbine modules.
  • Integrally shrouded blades with continuous contacting surfaces provide excellent damping capability for superior mechanical integrity.
  • Stage design provides precise control of radial clearances and throat areas to help ensure greater output and efficiency.
  • State-of-the-art technology and expertise are applied to our broad last stage blades portfolio for improved efficiency.

High Availability and Reliability

  • Our robust, reliable steam turbines are enhanced by control systems and the power of GE Digital solutions.
  • Our proprietary long-term testing program validates material behavior and ensures steam turbine component reliability.
  • Get extended maintenance intervals and increased turbine availability from advanced methods during the design phase. 

Enhanced Operational Flexibility

  • Advanced fracture mechanic methods provide reliable lifetime assessment of the steam turbine components and increased cycling capabilities.
  • An enhanced blade groove design reduces thermal stresses for increased rotor life.

Pioneering features that have become industry standards


Welded Rotors

  • With more than eight decades of welded rotor experience, our designs are proven and reliable.
  • Better access for ultrasonic testing equipment translates to higher reliability.

Shrink Ring Design

  • GE’s proven shrink ring design reduces distortion, allowing critical clearances to be maintained and sustaining performance over the life of the machine.
  • Compact design with smaller wall thickness provides flexible load cycling and faster startup times.

Single Bearing Design

Our multi-casing steam turbines have a single bearing between each turbine section for:

  • Avoidance of load shifting for higher reliability
  • Efficient shaft alignment for reduced construction time 
  • Shorter overall turbine shaft length for lower building costs

Advanced Sealing Features

  • Shaft and tip brush seals, developed in conjunction with our global research organization, improve leakage control when compared to more conventional sealing technology.
  • Abradable coatings on stationary seals enable the reduction of radial clearances, decreasing long-term performance degradation.

Family of High-Efficiency Last-Stage Blades

Our enhanced last-stage blade portfolio offers:

  • Dense staggered last stage blade sizes for project specific cold-end conditions and increased efficiency (up to 60’’ for 50Hz and up to 50” for 60Hz)
  • A robust design with stress-enhanced grooves and blade attachments for higher reliability·
  • Features such as full tip shroud, enhanced tip section with low shock loss, aerodynamic part span connector, and increased root-reaction that improve steam turbine performance
  • Advanced radial vortexing improves performance and hood integration over a range of loads

Advanced blading

Innovative blading technology is apparent in the steam turbines we manufacture through:

  • Modern, three-dimensional profile design that results in higher efficiency
  • High pressure (HP), intermediate pressure (IP), and low pressure (LP) front stage blades that are milled from a single forging for excellent mechanical integrity and higher reliability

LP Side Exhaust

  • Available for all D-series machines and enables ground level condenser connections, reduced centerline height, BOP equipment to be located on one side and lower plant construction costs.
