Wärtsilä Launches Next-Generation 46TS Engine

Hyderabad: Technology group Wärtsilä on Monday launched its next generation 46TS engine, which is designed to balance renewable energy, provide highly efficient baseload power, and can run on sustainable fuels in future.

The Wärtsilä 46TS large-bore engine has evolved from a long line of proven and reliable power plant engines, including the Wärtsilä 50 engine platform. The W50 engine is one of the world’s most successful power generating engines of all time, having delivered 55 million running hours around the world since 2008.

Using balancing engines to support intermittent renewables is a more viable path towards a net zero power system than a renewables-only pathway. Balancing power can reduce costs, emissions, and land use, as revealed in Wärtsilä’s recent global power system modelling report, Crossroads to Net Zero, which detailed the vital role of balancing power in delivering the energy transition.

The Wärtsilä 46TS is designed with sustainable fuels in mind, to ensure that when they become readily available, these engines can play an essential role in delivering 100% renewable power systems.

The engine provides a myriad of benefits for power producers, including:

· Next level efficiency and performance: Significantly improved over 51% engine efficiency saves fuel and reduces emissions, with excellent performance in extreme ambient conditions and at high altitudes.

· Improved output: The 46TS generates 23.4 MW/unit, meaning that fewer engines are needed to achieve large plant sizes.

· Greater flexibility: Rapid response to fluctuations with even faster ramp-up time (2 minutes) and no minimum up- or down-time requirements.

· Fast and cost-efficient installation: Fast and easy modular plant installation with high-quality, factory-tested modules bringing significant savings in total installed cost.

The Wärtsilä 46TS engine will be available from 2025.
