Who We Are

Exergy was founded in 2009 based on an insight from its founder, Claudio Spadacini, who launched the highly efficient Radial Outflow Turbine in the ORC market. This innovation has revolutionized the ORC sector. In a decade, Exergy has built a fleet of ORC systems that now totals nearly 500 MW, including those in operation and under construction. 
We have  installed of some of the largest ORC turbines ever built, with capacities of up to 20 MW.
Today, Exergy stands as the second leading player in geothermal binary plant installations worldwide.

Clean Power Generation

What We Do

We are experts in the design, engineering, manufacturing, and maintenance of Organic Rankine Cycle (ORC) systems for electricity production from renewable energy (geothermal, biomass, solar) and waste heat resources from industrial processes, gas turbines and engines employed in O&G processes and power stations

Thanks to our core technology, Exergy’s ORC systems perform with greater efficiency and flexibility than traditional steam Rankine cycle systems, helping customers to invest in clean energy projects with more profitable heat recovery solutions.

2011 to 2019: Exergy’s growth with the Maccaferri Industrial Group

After its founding in 2009, Exergy became a subsidiary of the Italian Maccaferri Industrial Group in 2011, which backed our growth year on year, allowing us to achieve an ORC fleet of 400 MWe worldwide in less than a decade.
