The company invested more than €15m in the biomass facility, which was constructed next to the existing 13MW Cornia 2 geothermal power plant.

The new facility is estimated to increase the geothermal plant’s output by over 30 GWh annually and reduce more than 13,000 tonnes of CO2 emissions.

It usesforest biomass to heat steam from an initial temperature of 150 to 160 degrees Celsius to 370 to 380 degrees Celsius.

Enel said it increases net electricity production capacity due to the increased enthalpy of the steam and the enhanced efficiency of the cycle.

Enel Green Power CEO Francesco Venturini said: "The integration of different technologies is a major step forward for the future of renewable energy.

"This plant, like our Stillwater facility in the United States, which combines the continuous generation capacity of medium-enthalpy, binary cycle geothermal technology with solar thermodynamic, and the Fontes Solar facility in Brazil, which integrates solar photovoltaic with wind while also using a stand-alone solar photovoltaic plant to reduce the consumption of Apiacas hydro plant construction site, will enable the optimisation of results and represents a replicable model that opens up new local energy, economic and employment opportunities."

The installed capacity of Enel Green Power exceeds 9,800MW. The company has around 740 plants operating in 15 countries.
