Generating sets based on medium speed reciprocating engines represent a solution to these challenges.
Multiple units arranged in modular power plants in the range 20MW-1GW provide the required flexibility whilst ensuring economical operation at any power plant output level.
The lean-burn spark ignited port-fuel-injection gas engine concept has been in constant development by the Rolls-Royce Power Systems company Bergen Engines AS since 1984, and offers an electrical efficiency of up to 50 %. By further utilising waste heat, in combined cycle or CHP mode, total efficiency can reach over 95%. This is currently used extensively in district heating applications, or industrial applications, where heat is used locally and the electrical power is either consumed locally in a micro grid or exported to the grid.
Designed to run with air excess ratio around 2.0 and above, both our medium speed gas and liquid fuel engines have excellent capability to meet quick and frequent load changes, which is essential for island-mode operation, such as isolated operation of microgrids. Start times of 3 from start command to rated power output have been committed to, using the Bergen B35:40V20AG2 genset.
A medium speed power plant can be built anywhere, and tailored to meet the specific requirements in every case due to its versatile building blocks. We offer modular and flexible power plant arrangements that have been developed over many years based on experience from a vast range of operating conditions from very low to very high ambient temperatures (-50C to +50C), and from very dry to tropical conditions.
To summarise, Bergen Engines’ power plant solutions enables the energy transition as economical and reliable balance and backup power to the grid, or as the back-bone of microgrids.
