Wärtsilä is to supply a 40 MW gas-engine power plant to Kerala State Electricity Board Limited (KSEBL) in southern India.
Kerala has a peak power deficit of approximately 300 MW and the plant – which is expected to be commissioned by April 2017 – will start and stop twice every day and run at full capacity for two four-to-five-hour periods, covering the morning and evening peaks in electricity demand.
It will comprise four Wärtsilä 34SG engines running on natural gas. The gas will be transported by a pipeline from a new LNG terminal in Kochi.
The engines will replace two units that run on low sulphur heavy stock oil and Wärtsilä said that “switching to natural gas will reduce the CO2 emissions by approximately 25 per cent”.
KSEBL chief engineer Susan Jacob said: “Wärtsilä engines have very high simple cycle efficiency. They are ideal for peaking power because they are capable of quick starts and stops. They provide the operational flexibility we need.”
