The 9EMax gas turbine is part of GE’s Fleet360 platform of plant solutions. In simple-cycle operation, it offers up to 37% efficiency and up to 145MW of output, while in IGCC operation, it offers up to 53.5% efficiency and up to 210MW of output.

GE Gas Power CEO Scott Strazik said: “We know our total plant services solutions and technical expertise in IGCC power plants were essential to successfully modernise this very important plant in only 10 weeks, which was absolutely crucial for Sokolovska Uhelna.”

GE also carried out rotor repair and fast stator rewind for two of its T240-370 generators to boost the plant’s performance.

The upgraded unit is equipped by GE´s On-line Monitoring System and linked to its Atlanta Monitoring & Diagnostics Centre. This enables in providing predictive maintenance support round-the-clock.

So far, GE has installed five 9EMax upgrades. Each of these units is operating commercially and two units have been in operation for more than 12 months.
