Assam Power Generation Corp. (APGCL) in northeastern India will replace several outdated gas turbine units with a 70-MW smart power plant supplied by Wärtsilä Corp.
The order includes seven 34SG natural gas-fired engines. The new plant is expected to be up and running by March 2018.
Wärtsilä said its engines can run at partial load while maintaining high efficiency, a feat not possible with the existing gas turbines.
“By absorbing the variations in the gas supply, Wärtsilä engines enable APGCL to produce more efficient power from the same amount of fuel without affecting the heat rate,” Wärtsilä said in a press release.
The power plant will operate in open-cycle mode, but APGCL will be able to convert it to a combined-cycle plant by installing waste heat recovery units. The modularity of Wärtsilä power plants allow operators to expand the power plant by adding more engines to meet increased demand.
"This project will further strengthen Wärtsilä's position in the utility power market in India that is looking for gas-based solutions," said Partha Paul, Business Development Manager at Wärtsilä.
Wärtsilä has an installed capacity of 4000 MW in India and 60 GW globally in 176 countries.
