The heart of plant performance

Steam turbines have on average 30 years of working life. As power producers in many parts of the world face increasing pressure to retire existing steam plants for economic or environmental reasons, the Advanced Steam Path provides a cost-effective option to increase the competitiveness and efficiency of existing steam plants with specifically tailored upgrades for high pressure (HP), intermediate pressure (IP) and low pressure (LP) cylinders. As a Fleet360 total plant solution, ASP can be packaged with other hardware and software solutions to further expand plant performance.
