Orlando, Fla. — An innovative new system that continuously monitors operating blades in gas turbines has surpassed 5,000 hours of operation, confirming that the technology is ready for commercialization.

Developed by Siemens Power Generation, with funding from the U.S. Department of Energy, the online monitor makes it possible for operators to replace turbine blades based on their actual condition, when the thermal barrier coating is worn or damaged. This capability optimizes the life of the blades, avoids the high cost of unscheduled replacement, and extends the time between preventative maintenance periods, increasing the availability of the plant.

The technological breakthrough could help keep electricity rates down by saving gas turbine utility operators an estimated $600 million per year.
