Enel Green finalises geothermal-biomass hybrid project in Italy
Enel Green Power SpA (BIT:EGPW) said Monday it has completed the construction of a 5-MW power plant in Italy’s Tuscany region that uses biomass to heat geothermal steam.
The new facility was built next to the existing 13-MW Cornia 2 geothermal power plant and is expected to increase the latter's output by more than 30 GWh annually. Enel Green has invested over EUR 15 million (USD 16.6m) in the biomass project.
The newly-installed power station uses virgin forest biomass to heat steam from an initial temperature of 150-160 degrees Celsius to 370-380 degrees Celsius. This boosts net electricity production capacity because of the increased enthalpy of the steam and the improved efficiency of the cycle, Enel Green explained.
When it comes to hybrid installations, the company also has a facility in the US that combines geothermal technology with solar thermodynamic, and a solar-wind park in Brazil.
