Power plant owners and operators need to secure a reliable and affordable energy supply while decarbonising their operations through investments in future-proofed assets that can run on sustainable fuels.
The Wärtsilä 46TS, Wärtsilä’s most flexible engine product, answers this challenge. This next-generation large bore engine is designed for balancing renewables and providing cost-efficient baseload. It brings improvements to a variety of essential features, delivering the security of supply you need now plus the future-proof technology to help ensure the long-term success of your business.
High mechanical output (23.4 MW/unit) means fewer engines are needed to meet demand.
High efficiency (51.3%) saves fuel and reduces emissions, plus excellent performance in extreme ambient conditions and at high altitudes.
Flexibility
Rapid response to fluctuations with fast ramp-up time (2 minutes), plus no minimum up or downtime requirements.
The Wärtsilä 46TS’s high electrical efficiency reduces emissions and helps to secure your investment by reducing fuel consumption. The high level of flexibility allows your plant to respond to fluctuations in renewable power sources and opens up new revenue streams.
The flexible Wärtsilä 46TS is ideal for balancing fluctuations in renewable energy sources. The engine provides fast-ramping (2 min) balancing power to maintain grid stability and can operate optimally even at minimal loads, with unlimited startups and shutdowns at no additional cost. Thanks to the innovative modular design, Your plant can be quickly and easily scaled up as the share of renewables in the power system increases.
The engine’s high electrical efficiency reduces emissions and helps to secure your investment by reducing fuel consumption, even when gas prices are volatile. These capabilities make the Wärtsilä 46TS ideal for baseload generation. Its two-stage turbocharger system ensures full power at -55ºC/-67F to +55ºC/131F, making it suitable for power generation in a wide range of geographical locations.

Prefabricated power plant modules with streamlined, simplified interfaces mean your Wärtsilä 46TS engine power plant can be up and running quickly for a faster return on your investment. The modular setup also means your plant can be scaled up as needed, allowing you to integrate more renewables in the future.
The heart of your plant is the power unit, comprising the engine and associated essential equipment. The unit can be installed and ready to start generating power in a matter of days. The power unit can be complemented with process modules that enable easy integration of auxiliary equipment, process media and filtration. You can also add electrical modules to enable easy integration of low and medium-voltage systems.
With fuel-flexible engines, you can minimise the risk of investing in assets that may become unprofitable or even obsolete. The Wärtsilä 46TS has been designed to operate on various gaseous and liquid fuels, including natural gas, biogas and hydrogen blends up to 25%.
Whatever fuels become dominant in the future, the Wärtsilä 46TS will be able to run on them thanks to its groundbreaking modular design, which makes it easier than ever before to convert to sustainable fuels as they become available.

Wärtsilä 46TS engine provides improved output and efficiency to save fuel and costs, with future proof technology that can run on sustainable fuels
Technology group Wärtsilä launches today 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.
Anders Lindberg, President of Wärtsilä Energy, says: “The energy transition cannot be achieved by renewable power alone – we need flexible, highly efficient engines to support wind and solar power during times of low generation. The flexible 46TS engine offers exactly that, expanding our existing technology offering to balance renewables and operate cost- effectively on baseload power.
“This engine is built on our 85 years of engine expertise, incorporating everything we have learned to develop our latest and greatest solution.”
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:
To support the W46TS, Wärtsilä provides tailored high-quality services to maximise reliability and profitability. Wärtsilä Lifecycle services, with optimised operations and guaranteed performance, ensure the power plant's performance and competitiveness. A technical service network provides expertise and support near customer and via remote monitoring.
The Wärtsilä 46TS engine will be available from 2025. Last month, Wärtsilä announced the first order for the 46TS engines placed by Kazakhstan Caspian Offshore Industries (KCOI). The engines will support KCOI's new 120 MW power plant and additionally, the first hybrid power project of its kind in Kazakhstan, which integrates the engine power plant with wind and solar power.
