Our projects

Our projects for the environment, biodiversity and the community are the concrete expression of our commitment and our passion to promote sustainable development based on renewable resources.


In 2019 we implemented the plastic-free project, identifying certain initiatives to eliminate or reduce the habits that generate plastic in our business activities.

We are proud of the active participation of the entire Group, confirming the increasing and widespread awareness of more sustainable lifestyles and a close focus on the environmental impact of our activities.

2,500 kg of plastic saved, enabling the avoidance of around 15 t of CO2 in just four months in 2019, with estimated savings of approximately 26 t of CO2 per year.

Wind turbine blades: fully sustainable plants

Thanks to the Reblading project, we are replacing the turbines in our oldest wind farms with a lower number of latest-generation, high-output models. This enables us to guarantee the sustainable management of the old wind turbines, a significant number of which have reached the end of their technical life.

This value was also confirmed by a study by ANEV, the Italian Wind Energy Association, in 2017, which showed how almost all of the materials used to construct a wind turbine (tower, nacelle and blades) are recyclable, making it easier to dispose of at the end of its useful life.
Thanks to this study, it is possible to identify the destination of all parts of a turbine, driving innovation with a view to sustainability.
Material Origin Scenario
Steel Tower and other components 90% re-usable
Cast Iron  Foundations and other components 90% re-usable
Copper Electrical components 95% re-usable
Alluminium Electrical components and structure 90% re-usable
 PVC Plastic Other components 100% re-usable
Fibreglass Blades and nacelle structure 100% re-usable
Lubricating Oils Turbine's mechanical parts 90% re-usable

We build with the environment in mind

We build with the environment in mind
Our plan in Italy focuses on the technological renewal of the wind turbines in Italy through the Repowering and Reblading project. Repowering means replacing the old wind turbines with latest-generation, high output models, while Reblading refers to the replacement of the blades on existing wind turbines with latest-generation blades. The project avoids the need to build a new plant, which would have greater impacts on the environment, and helps to generate value:
  • The optimal use of the plant site, with the efficient use of existing structures and infrastructures; - Continuous protection of regional diversity, ensuring that plants remain "in-keeping" with the environment. Furthermore, a plan to monitor resident and migratory birds has been adopted, based on the procedure relative to the "Protocollo di Monitoraggio dell'Osservatorio Nazionale su Eolico e Fauna" (Monitoring Protocol of the Italian Wind and Wildlife Observatory), produced in collaboration with ISPRA, ANEV (the Italian Wind Energy Association) and the NGO Legambiente, in line with industry practices;
  • Reduction in noise pollution, with lower sound emissions thanks to innovative and high-performance blades;
  • Reduction of the so-called "barrier effect" and land use, with positive impacts in terms of the landscape, thanks to the reduction in the number of wind turbines; 
  • Restoration of currently occupied areas earmarked for dismantlement, returning the land to its natural state and original vegetation.

Corbara wood: from waste to resource

Corbara wood: from waste to resource
Waste wood transported by the River Tevere often accumulates in Lake Corbara, where it goes entirely untreated.

To protect the environment, we have designed a solution to enhance this resource. Following constructive dialogue with the Umbria Region, we agreed upon the possibility to consider the wood that accumulates on the lake shore as material that can be reused as part of the waste-to-energy system or in the wood industry.

Thanks to this virtuous recovery activity, the amount of waste sent for recovery exceeded 88% (+6% compared to 2018).

Alviano Oasis

Alviano Oasis
In the eastern part of the Alviano lake, slightly upstream of the dam of the same name, there is an oasis that occupies around 400 of the lake's 900 hectares which hosts many resident bird species and, thanks to its geographical position, has also become a stopping point for migratory birds. It has all the typical features of humid freshwater areas - marshes, a pond, swamps, a water meadow, one of the largest woods in Central Italy - and is home to a huge number of bird species, such as great white egrets, stilt birds and ospreys, and many different amphibians, such as crested newts and agile frogs.

The "Heronry" is home to over a hundred mating pairs of grey parrot, cattle egret, little egret, squacco heron, black-crowned night heron and cormorant. The mammals that live in the oasis include foxes, boars, badgers, porcupines and hedgehogs and extremely rare wildcats. Furthermore, in 2019 as part of the "Bee Safe" project launched by the WWF, an "insect garden" was created in order to attract several species of pollinating insects. This year's activities involved the maintenance of the "flooded prairies", which, following the flood of 2012, were filled with mud, with a significant variation in morphology and the consequent growth of weeds.

With the mud having been removed in past years, activities in 2018 and 2019 concentrated on the cutting of weeds which, reaching up to 4 metres high in some places, prevented many birds from stopping and blocked tourists' view of the species. Moreover, a drystone wall was built to improve a section of the Oasis by providing a passage for reptiles.

These measures immediately revitalised the Oasis from both a natural point of view and in terms of tourism, which saw considerable development: in 2019 the Oasis welcomed around 6,700 visitors. The redevelopment of the watchtower, the refurbishment of the observatory and the educational workshop, and the creation of a photography hide by the pond on the water's edge contributed to improving the touristic attraction of the site. In particular, around 1,400 photography enthusiasts were able to develop their passion at the Oasis.

Thanks to hides perfectly integrated among the wildlife, ideally positioned in relation to the sun and close to the feeders that attract the animals, we are able to offer a suitable environment for those devoted to this hobby. There were plenty of visits from school pupils who were able to study the life of the marsh in a laboratory equipped with microscopes, cameras and screens, gaining first-hand experience of all the phases of a biology research project. The events organised for industry experts, which offered an opportunity to discuss naturalistic topics, were extremely well received.

Thanks to an agreement between ERG and the province of Terni, the Oasis of Alviano has been managed by the WWF since 1990 and is currently one of the top locations in Italy for nature photography, drawing enthusiasts from around the country to capture the beauty of its views.
