Wartsila engines to replace gas turbines at Assam plant

Wärtsilä is to supply a 70 MW gas engine plant to Assam Power Generation Corporation (APGCL) in north-eastern India.

The Finnish company will deliver seven of its 34SG natural gas engines which will replace existing gas turbine unitsWartsila gas engine plant in Assam.

APGCL is making the switch because it says when gas is scarce, the plant needs to be run at part-load, and this is difficult with the existing turbines.

Wärtsilä said that by absorbing the variations in the gas supply, the engines will enable APGCL “to produce more efficient power from the same amount of fuel without affecting the heat rate”.

Initially, the plant will operate on an open cycle mode, but APGCL has the option of converting it to combined cycle by installing waste heat recovery units.

Currently, Assam has a high dependence on electricity imports. The new plant is intended to increase the region’s energy independence and help to meet its increasing electricity demand.
