The investment will support the company’s growth in the energy efficiency market and help drive further adoption of its unique and innovative Electric Turbo Compounding (ETC) technology.

Bowman Power Group’s Electric Turbo Compounding (ETC) solution recovers waste energy from the exhaust of reciprocating generator sets (gensets) and converts it to free, grid quality electricity, significantly improving the energy efficiency of the genset without increasing its footprint or maintenance requirements.

This reduces fuel consumption or provides around 10% additional free power, as well as cutting CO2 emissions by an equivalent amount. The technology is proven in the field, with over 600 systems deployed worldwide, which, to date, have accumulated over 12,000,000 running hours, generated over 350GWh of free energy and reduced CO2 by over 120,000 tonnes. Cornerstone customers include Cummins and Wärtsilä.
