Next generation engine helps balance renewables and improve power plant performance
Technology group Wärtsilä launched its 46TS engine, which is designed to balance renewable energy, provide efficient baseload power, and have the ability to run on sustainable fuels in the future.
Using balancing engines to support intermittent renewables is a more viable path towards a net zero power system than a renewables-only pathway, says Wärtsilä, noting that its recent global power system modelling report detailed the role of balancing power in reducing costs, emissions, and land use.
Wärtsilä Energy president Anders Lindberg 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.”
The large-bore engine is designed for the use of sustainable fuels when they become readily available. Additional benefits include:
- Efficiency and performance: 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 faster ramp-up time of two minutes and no minimum up- or downtime requirements.
- Fast and cost-efficient installation: Fast and easy modular plant installation with high-quality, factory-tested modules lowers total installed cost.
Wärtsilä Lifecycle technical service network provides onsite and remote monitoring aimed at ensuring optimised operations, performance, and competitiveness.
