    Energy efficiency

    Power plants based on multiple generating units are far more fuel-efficient than traditional single-unit power stations. They also serve efficiently on part load and in demanding conditions, enabling high dispatch even at high temperatures and altitudes.

    We offer the highest available simple cycle energy efficiency of any current technology, over 50%. On top of that, our proprietary Flexicycle™ solution combines the advantages of a flexible simple cycle plant with the superb efficiency of a combined cycle plant.

    Fuel flexibility

    Fuel flexibility

    Wärtsilä’s multi-fuel plants enable the continuous choiceof the most feasible fuel, including solutions for liquid and gaseous fuels as well as renewables. The possibilities gained from multi-fuel plants and fuel conversion solutions represent a hedge for the future. The role of natural gas in power generation is expected to grow significantly over the coming years.

    Operational flexibility

    ​Wärtsilä power plants can be configured to suit any power need, from steady baseload generation to ultra fast, zero-emission, non-spinning grid reserve for any contingency situation, or even grid black start. They can supply megawatts to the grid in less than a minute from start-up and reach full load in less than five minutes. They are designed to start and stop – at the push of a button – time after time with negligible start-up costs and with no impact on the maintenance schedule.

    Operational Flexibility



    The multi-unit configuration allows plant availability and reliability over 99%. Wärtsilä’s internal combustion engines are designed for flexible operation, meaning that the maintenance schedule is not negatively affected by the number of starts, stops or load variations. Furthermore, our highly standardised solutions built on pre-tested modules ensure an on-time start of commercial operation. Hence, you can always be sure that the plant will be ready to supply power when you need it.
