What is ETC?
Electric Turbo Compounding (ETC) technology is our solution to the challenge of improving energy efficiency for the stationary power generation industry
Increased efficiency for the power generation industry
At Bowman, we believe there is a strong environmental and economic duty to ensure that, where reciprocating engines are used to generate power, fuel is consumed as efficiently as possible. Electric Turbo Compounding (ETC) technology is our solution to the challenge of improving energy efficiency for the stationary power generation industry.
The use of fossil fuel based power generation, particularly in developing economies, is predicted to continue for decades. This is at odds with the global need to reduce carbon emissions, of which, a high percentage is produced by the power sector worldwide.
Our ETC products make gas and diesel-powered gensets work more cleanly and effectively, by recovering waste energy for the genset exhaust to improve power density and fuel efficiency. The technology is equally suited to new-build and retrofit applications, for engines in the 150kW-2MW range. Dependng on engine size, either a single or twin ETC system will be required – see below. We have also developed ETC products for much larger engines with a waste gate, such as the Wärtsilä 34SG, a 9MW gas engine. Read a case study.

ETC Technical Specification
Electric Turbo Compounding (ETC) technology is our solution to the challenge of improving energy efficiency for the stationary power generation industry.
The ETC 300 is suited to gas and diesel-fulled gensets in the 150kW-400kW range as a single system.
The ETC 600 is suited to gas and diesel-fulled gensets in the 300kW-600kW as a single system and in the 500kW-1200kW as a twin system.
ETC 1000 is suited to gas and diesel-fuelled gensets in the 600kW-1100kW range as a single system and 1100kW-2000kW gensets as a twin system.
ETC for Open Genset
The Electric Turbo Compounding system is suitable for new build or retrofit application for a gas and diesel-fuelled open genset, improving overall energy efficiency and power density.
ETC for Containerised Gensets
The Electric Turbo Compounding system is equally suited for integration with containerised gensets, improving the efficiency of rental units.
