The launch aligns with Wärtsilä’s ongoing research into power system optimization. Its recent report, Crossroads to Net Zero, underscores the benefits of balancing engines in combination with renewables, highlighting their role in achieving emissions reductions more efficiently than relying solely on renewable energy sources.
The Wärtsilä 46TS engine builds on the proven performance of the Wärtsilä 50 engine platform, which has logged over 55 million operating hours globally since 2008. The new model delivers more than 51% engine efficiency, reducing fuel consumption and lowering emissions. With an output of 23.4 MW per unit, power plants can optimize space and infrastructure by meeting capacity requirements with fewer engines.
A key feature of the 46TS is its rapid response capability. Designed for grid stabilization, the engine can ramp up within two minutes, providing critical flexibility to compensate for fluctuations in wind and solar power generation. This responsiveness is essential as energy markets prioritize reliability alongside decarbonization efforts.
The 46TS engine is engineered with long-term sustainability in mind. Its adaptable architecture supports compatibility with sustainable fuels, ensuring relevance as the industry moves toward fully renewable power systems. This forward-looking approach positions the engine as a key asset in energy transition strategies.
Wärtsilä has secured an initial order for the 46TS engine from Kazakhstan Caspian Offshore Industries. The 120 MW hybrid power project will integrate these engines with wind and solar installations, demonstrating the technology’s role in hybrid energy solutions.
