Wartsila has launched its next generation 46TS engine, designed to balance renewable energy, provide efficient baseload power, and run on sustainable fuels in the future.

The engine, which has evolved from the Wartsila 50 engine platform, 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 highlighted in Wartsila's recent global power system modelling report, Crossroads to Net Zero.

Anders Lindberg, President of Wartsila 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 Wartsila 46TS engine offers several benefits for power producers, including next-level efficiency and performance, improved output, greater flexibility, and fast and cost-efficient installation.

Wartsila provides tailored high-quality services to maximise reliability and profitability, including Wärtsilä Lifecycle services, which optimise operations and guarantee performance.

A technical service network provides expertise and support near the customer and via remote monitoring.

The Wartsila 46TS engine will be available from 2025, with the first order placed by Kazakhstan Caspian Offshore Industries (KCOI) for its new 120 MW power plant and the first hybrid power project in Kazakhstan, which integrates the engine power plant with wind and solar power.
