NTPC Limited, GE and Gujarat State Electricity Corporation Limited have said that the steam turbine modernisation project has improved efficiency at the Ukai power station.

A company statement said that after the plant modernisation project, the plant efficiency has increased by 5.5 per cent.

The retrofit will extend the unit’s life by 25 years, and it restored its output back to its original capacity of 200 MW. Final tests at Ukai’s plant displayed more efficient operations that will help the plant reduce its coal consumption by more than 140,000 tons per year and reduce carbon dioxide emissions by 180,000 tons per year.

Reducing coal consumption will result in approximately $7 million savings for the utility every year, the statement added. The project was completed on May this year.

Earlier this year, GE had said it would modernise NTPC’s three 200-MW Ansaldo steam turbines with Advanced Steam Path (ASP) technology at the Ramagundam station. The upgrades will increase turbine output and improve efficiency and flexibility, according to the statement.
