GT13E2

The GT13E2 is a 50 hertz E-class gas turbine that began as an ABB design, passed to Alstom and is now offered by GE, which acquired it with Alstom's power business in 2015. ABB introduced it to the market as a 166 MW machine with a turbine inlet temperature of 2,012 degrees Fahrenheit and a compressor pressure ratio raised from 13.9 to 15.0 over the earlier GT13E. Alstom dates first operation to 1993 and says it was the first gas turbine to offer a switchable operating concept, one mode tuned for performance and another that greatly extends inspection intervals. It can burn almost any natural gas composition or switch to distillate on line. By 2015 Alstom reported 169 units sold in 34 countries, about 30 GW in operation, and a 2012 upgrade that lifted output above 200 MW at 38 percent efficiency, with a later MXL2 package; POWER says the 2017 rating reaches 210 MW. It runs between 30 and 100 percent load within emissions limits.
