We produce energy using a combination of programmable and non-programmable production sources (wind, water, natural gas), which are complementary, flexible and dynamic, with a common specific goal: to generate clean energy. Programmable sources can be managed according to energy demand and make it possible for us to take part in the electricity market as system operators.
Since electricity cannot be stored, production must always match consumption. Efficient programming of our production assets is therefore essential: this is what our Energy Management department deals with as it works to optimise production according to the needs of the electricity market.
Our business model is based on the clear choice of being a green operator whose electricity production mix is balanced between programmable (water and natural gas) and non-programmable sources (wind and sun).
Today 56% of our capital is employed in wind power, a non-programmable source (it was 20% in 2008).
Since 2015, we have added hydro power (which is programmable) by acquiring the Terni Complex, decisively venturing into the field. At the same time, the share of natural gas (thermoelectric power, programmable) in our portfolio has gone down from 32% to 11% and now includes only our high-efficiency and low-emissions Priolo cogeneration plant, which produces Energy Savings Certificates.
In January 2018, thanks to an important acquisition, we have made our entry into the solar business and today we are operating in eight different Italian regions.
Management of the industrial and commercial processes of the ERG Group is carried out by the subsidiary ERG Power Generation S.p.A. which directly carries out:
- the unified Energy Management activity for all three generation technologies in which the ERG Group operates;
- the Operation & Maintenance activities of the "Centrale Nord" plant, of its own Italian wind farms and of some of the wind farms in France and Germany.Through ERG France and ERG Germany it performs technical and administrative services in France and Germany both in favour of Group companies and of third parties.
