Renewably-sourced energy in Italy

We dedicate our work to researching and producing biofuels from biomasses and wave power, whilst with Plenitude, we develop projects to generate and sell wind and photovoltaic energy.

In addition to the traditional businesses set up in Italy, the development of energy from renewable and more sustainable sources is becoming increasingly important to Eni, and with Plenitude, we are concentrating our efforts on the development of innovative technologies for the creation of onshore and offshore solar and wind energy farms. We are also working on research into harnessing tidal wave power and the production of biofuels also from biomass, an additional solution that establishes our path towards the energy transition which is aimed at contributing to the reduction of emissions in the transport sector, by exploiting agricultural by-products such as grains and vegetables production as renewable energy sources.

We are progressively increasing installed capacity nationwide

After a path that saw us initially working on developing photovoltaic plants in industrial areas owned, nowadays in Italy we are combining renewable energy activities with our subsidiary Plenitude and, thanks to this strategic choice, we are further expanding the number of retail customers along with the offer of energy solutions. Installed capacity nationwide is growing steadily, with the aim of achieving the target of zero net Scope 1, 2 and 3 emissions in Italy by 2050 (Net GHG Lifecycle Emissions) and the cancellation of the related emission intensity (Net Carbon Intensity), which refers to the entire life cycle of the energy products sold.Thanks to the skills we have consolidated over the years and to our work with high-level partners in the sector, we offer extremely comprehensive services and we also develop knowledge and organisational platforms that have already been used in the Italian market on a global scale.

The plants now operating in Piedmont, Lombardy, Puglia and Sardinia

The first plant belonging to the company Eni New Energy (today a 100% subsidiary of Plenitude) was the 1 MW photovoltaic plant near to the Green Data Centre in Ferrera Erbognone (Pavia). The energy produced is entirely consumed by the facility and serves to compensate the power consumption of Eni's HPC5 and HPC4 supercomputers.We then built the two large-scale photovoltaic plants in Sardinia Assemini (Cagliari) and Porto Torres (Sassari). Also through Eni New Energy, we started production of a photovoltaic farm in Volpiano (Turin), built inside Eni's fuel depot, and in 2021 we started production on three 35.2 MW wind farms in Laterza (Taranto), which produce around 90 GWh per year and thanks to which 37,500 tonnes of CO2 emissions will be saved each year too (source: Report ISPRA).


The farms in operation and being built in Puglia, Basilicata, Abruzzo, Sicily and Sardinia

In 2021, through Eni New Energy (Plenitude 100%), we acquired 100% of the portfolio of 13 onshore wind farms in Italy, with a total capacity of 315 MW, as well as a portfolio of 256 wind turbines which were already in operation in Sicily, Puglia, Basilicata and Abruzzo and the 35 MW just built in Puglia. Thanks to these latest acquisitions, we have become one of the leading players in the country. Our commitment in Italy was further strengthened by our partnership with Cassa Depositi e Prestiti, with which we established the company GreenIT (51% Plenitude, 49% CDP Equity) for the development, construction and operation of plants to produce electricity from renewable sources. The JV is active in the development and construction of greenfield plants (by exploiting the CDP Group and the government’s real estate assets), the repowering of end-of-life plants and the construction of authorised projects. In 2022, again through GreenIT, we acquired a further portfolio consisting of four onshore wind farms in Puglia with a total capacity of 110 MW, and signed an agreement for the construction of two offshore floating wind farms in Sicily and Sardinia, with a total capacity of around 750 MW. 

Always in 2022, through Plenitude, we entered a new partnership with Infrastrutture S.p.A. to develop solar and wind power projects in Italy and Spain by acquiring a 65% stake in Hergo Renewables S.P.A., a company that holds a portfolio of projects in the two countries with a total capacity of approximately 1.5GW. The plant of first project, a photovoltaic plant in Montalto di Castro (VT) with a capacity of 37 MW, is expected to come into operation in the second half of 2023. Furthermore, in December 2022, Plenitude signed an agreement to acquire 100% of PLT (PLT Energia S.r.l and SEF S.r.l. and their respective subsidiaries and affiliates), an integrated Italian group producing electricity from renewables and supplying energy to retail customers, with a 1.6 GW renewable capacity portfolio in Italy and Spain and 90,000 retail customers. Through this synergistic operation with its portfolio of renewable assets and retail customers, Plenitude is strengthening its presence in Italy.


The exploitation of tidal wave motion (ISWEC)

Wave power is considered the most constant of the renewable energies because, unlike the sun and the wind, it does not stop and it is also considered the “densest” because it is the concentration of energy produced by the wind, which in turn concentrates the energy produced by the sun heating of the atmosphere. The Inertial Sea Wave Energy Converter (ISWEC), developed together with a spin-off company of the Polytechnic University of Turin, makes energy immediately usable for offshore plants or supplies it to the electricity grid to power coastal communities. In 2019, we launched a project to develop industrial-scale wave power production plants with our partners CDP, Terna and Fincantieri. In 2020, we have further strengthened the partnership with the inauguration of an all-Italian marine energy research laboratory.


Through Eni Rewind we contribute to the redevelopment of territories

Through our environmental company, we make brownfield land which is no longer productive available in order to accommodate plants for the production of green energy which will be used for the needs of the group's industrial assets and partially supplied to the grid. The plants set up in Assemini, Gela and Porto Torres allow us to pursue our projects regarding the circular economy, CO2 reduction and land occupation and exploitation.
