Flexible and modular engine based power plants installed in our own designed self-contained engine packages, can be supplied with all the components and auxiliaries needed to construct a fully working power station with the possibility of extension whenever additional modules are needed. It is a cost efficient solution to providing electrical power. The power generation solutions suit for base load, combined cycle, grid support, stand-by and peak shaving.


Bergen Engines combined heat and power?

Combined Heat and Power
Many engine installations require heat recovery, whatever their applications. Our experience ranges from remote power supply to co-generation and tri-generation, with efficiency levels beyon 95% in climates ranging between the arctic freeze of Svalbard, and hot and humid Bangladesh. We support our customers delivering high efficiency power plants for district heating, industrial CHP, greenhouses and tri-generation.


Bergen Engines mechanical drive?

Hybrid mode
At hybrid power plants, percentage of produced electricity typically varies between renewable energies, generating sets and energy storage. Our flexible and cost effective reciprocating engines are the perfect match to renewable energy. They are capable of fast and frequent starts and stops, and manage dynamic load response for grid balancing effortlessly.
