Infosys - Next Generation Gas Turbine Upgrade

A European power generation major wanted to upgrade the existing fleet with a new Heavy duty class capacity and capability milestone using a new Hot Gas Path design.

The primary requirement was to increase efficiency at the high-power output and flexibility.

Key Challenges

New combustion technologies to handle fuel alternatives aiming to reduce carbon emissions
Higher firing temperatures, lower emissions and increased operational with fuel flexibility
Product needed to be developed and deployed in a record time of under one year to meet client requirements
