PLTD Pesanggaran, Bali

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.

Marquette Energy Center, USA

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.
