Gorizia power plant

Energia Capitale ESCo has been managing and running the Gorizia thermoelectric plant, located in Via Giuseppe Ressel since 2019. The Gorizia plant produces:

  • 60,000,000 kWh of electricity per year;
  • 80,000,000 kWh of thermal energy per year.

Our goal is to achieve the sale of thermal energy as an addition to electricity, through a district heating network that would save about 50% in methane gas costs.

The plant provides for an annual reduction in atmospheric emissions of carbon dioxide, the gas responsible for the greenhouse effect.

Management and Conduction

The plant had been at a standstill since 2014, but thanks to our revamping project, production was relaunched in May 2021. Revamping a system means overcoming the design and technological limits of an existing or previously operational plant and integrating the original systems with current and cutting-edge solutions.

A project collaboration with Rolls Royce involved their specialized technicians carrying out an assessment of the plant, aimed at verifying the following conditions:

  • level of failure / degradation of components;
  • the extent to which components and materials had been inadequate from plan;
  • the requirements for bringing the entire structure up to standard;
  • residual life of the plant.


The plant assessment carried out by the technicians resulted in various interventions, including:

  • replacement of turbine engines;
  • replacement of electrical systems and related control panels;
  • installation of a new cogeneration system;
  • installation of a performance monitoring system.

The power plant is made up of modular units whose Rolls-RoyceBergen engines are fueled by methane gas with a nominal power of 3,350 kW each, located inside a warehouse in the Gorizia industrial complex.

The cogeneration system has a total electrical power of about 10 MWe, powered by engines with “Leanburn” gas supply (lean combustion) with controlled ignition (using spark plugs), of the “medium speed” type (1,000 r.p.m.), with a recovery system which uses the heat generated by the actual engines themselves.
