In the stationary sector, MAN Diesel & Turbo low and medium speed engines are primarily used in power plants and for emergency power supplies. To this end, we deliver turnkey system solutions for land-based or floating power plants with outputs up to 400 MW. Diesel engines are especially suitable for generating electricity because they achieve the highest level of thermal efficiency, so enabling the conversion of primary energy into electrical energy in a very cost-effective way. The degree of efficiency of a large diesel power plant is between 46 and 52 per cent, making it the highest of all the combustion engines. By way of comparison, the average degree of efficiency of coal-fired power plants worldwide stands at an average of 30 per cent.

MAN Diesel & Turbo couples the already extremely high efficiency of diesel engines with a raft of different power plant technologies that help to protect the environment. These include a tremendous degree of fuel flexibility, enabling the use of eco-friendly bio-fuels alongside fossil fuels such as heavy oil and gas. Systems to use waste heat, as in the Diesel Combined Cycle ensure an appreciable increase in efficiency in stationary power generation and help to reduce specific fuel consumption in diesel power plants. Measures inside the engine and aftertreatment systems from MAN Diesel & Turbo such as SCR technology ultimately ensure that our power plants comply with and in some cases out-perform the world's existing legal emissions guidelines.
 
MAN Diesel & Turbo power plants are also ideal for balancing out the fluctuations that can occur with solar or wind energy generation. In the form of hybrid power plants, diesel power plants powered by bio-fuels for example can always spring into action to cover the basic load demands if there is not enough wind or solar energy.
