The Wärtsilä 50DF is a four-stroke multi-fuel engine generating set. It allows instant switching to alternative fuels, should price instability or delivery challenges affect the use of the primary fuel.
Wärtsilä 50DF operates on the lean burn principle, which reduces peak temperatures and lowers NOx emissions considerably. High efficiency in a small footprint combined with great reliability and flexibility makes this solution ideal for various applications. Wärtsilä engine power plants can be delivered both as EPC and Equipment Delivery contracts.
With plenty of wind and sun, South Australia has become a forerunner in renewable energy. A high share of renewables needs, however, to be balanced by flexible power generation. To improve its energy reliability, AGL Energy Limited, one of Australia’s leading integrated energy companies, turned to Wärtsilä for dispatchable power.
Indonesia is one of Asia’s fastest growing economies in terms of energy consumption. With a steadily growing population of nearly 270 million and an increasing rate of urbanization, there is significant need for a reliable and guaranteed supply of power throughout the archipelago. In recent years, the country has been successful in increasing installed capacity and investments in infrastructure to both improve the reliability and efficiency of the main grids such as the Java-Grid and increase electrification of the small grids.
When the temperature drops to –40 degrees Celsius, blackouts are not an option. In order to secure a reliable energy supply and enable more renewable energy, Marquette Board of Light and Power (MBLP) in Michigan, USA, opted for Wärtsilä Smart Power Generation technology. As an added benefit, the ultra-flexible power plant provides a new source of income by following real-time electricity prices. The dual-fuel plant replaces old coal-fired capacity.
In September 2011, Barrick Gold Corporation acquired a majority share in a gold mine located some 100 kilometres from the Dominican capital, Santo Domingo. The mining company quickly placed an order for a state-of-the-art Wärtsilä power plant to satisfy the needs of their new power-hungry mine
