6 Frequently Asked Questions about “Progress of Italian energy storage reservoirs”
How will Italy develop utility-scale electricity storage facilities?
To develop utility-scale electricity storage facilities, the Italian Government set up a scheme that was approved by the European Commission at the end of 2023. Italy will promote investments in utility scale electricity storage to reach at least 70 GWh, and worth over Euro 17 bn, in the next ten years.
Why is energy storage important in Italy?
In addition, electricity storage is critical to avoid congestion in the power grid since most of the renewable production originates in Southern Italy but is consumed mostly in the north. Therefore, PNIEC also provides for the installation of new energy storage infrastructure with the aim of reaching 22.5 GW of installed storage capacity by 2030.
How will Italy invest in electricity storage?
Italy will promote investments in utility scale electricity storage to reach at least 70 GWh, and worth over Euro 17 bn, in the next ten years. The new storage capacity will be acquired through tenders published by Terna, the manager of Italy's high voltage grid. The next tender will be released in 2024.
Does Italy need electricity storage?
As Italy's energy mix is increasingly composed of variable renewable energy sources, electricity storage will be needed to integrate power generated by renewables into the national grid and make it available when sun and wind energy are not accessible.
Which reservoirs are reducing sediment load in Italy?
The reservoirs situated in north-eastern Italy across the Piave river have led to a decrease in the sediment load from 1 Mm 3 to 0.145 Mm 3 per annum (Surian et al., 2009). The Fusino reservoir located in northern Italy has lost 6% of the storage volume as of 2015 with respect to its operation year 1974 (Pagliari et al., 2017).
What is the average age of a reservoir in Italy?
The reservoirs studied have an average age of 78 years as of 2021, with the highest loss of capacity observed, equal to 100%, for Ceppo Morelli. For the fifty Italian catchments covering north, south, central and islands of Italy, we found the mean annual sediment yield varying between 17–4000 m 3 /km 2. year.
