Systems for storing energy are essential to Italy’s decarbonization and energy security. Medium- to large-scale storage systems are less frequent in Italy, where the majority of energy storage facilities have been established in conjunction with small-scale solar power plants. It is still quite uncommon to find storage systems coupled with wind turbines, fuel cells, or thermoelectric power plants.
Energy production from renewable sources might be improved by the integration of storage devices, which would also increase the stability and security of the transmission and distribution network.
The Italy Energy Storage Market accounted for $XX Billion in 2023 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2024 to 2030.
Rock-based Energy Storage Facility was introduced by Enel and Brenmiller in Italy. The majority of renewable energy sources are seasonal and rely on a natural energy source.
Storage systems are therefore necessary to lessen the pressure on the power grid and excessive energy demands. Thermal energy storage (TES), or heating the material and recovering energy from that heat as needed, is one technique for addressing such requirements.
The use of thermal storage can increase overall efficiency while lowering expenses and carbon dioxide emissions. The two main methods of thermal storage are rock-pile storage and water storage, which both employ a variety of technological approaches.
Water has great thermal conductivities, however, rocks or concrete can be heated to considerably higher temperatures and offer high overall volumetric conductivities. To put things in perspective, 2.8 cubic metres of insulation would be able to supply a single home with the energy needed to fulfil 50% of its heating needs.
Therefore, energy storage in rocks is a viable and developing method to store extra wind or solar energy. Two concrete thermal storage systems are now being developed in Germany and one in Denmark, and these technologies have attracted attention on a global scale.
NEC successfully commissions the largest renewable Energy Storage System in Italy. The largest distribution system operator in Italy, Enel Distribuzione, a subsidiary of the Enel Group, received the commissioning of an Energy Storage System (ESS) from NEC Corporation today. The ESS is the largest in Italy and one of the largest in Europe since it can store two-megawatt hours (2MWh) of renewable energy for release into the grid as needed.
In the province of Calabria, where renewable energy sources, including as photovoltaic and wind production facilities, have been largely adopted, the ESS has been connected to the Chiaravalle primary substation.
The high proportion of inherently variable and intermittent renewable energy resources may cause grid reliability issues due to reverse power flows from the medium voltage (MV) grid to the high voltage (HV) grid, which occurs when the amount of renewable power generated exceeds current consumption levels. It raises new concerns about system stability, voltage quality, and peak load control. At all times, supply and demand must be balanced.
Voltage and frequency variations could impair or even kill electronic devices if they are not. Enel Distribuzione is testing various peak shaving, power balancing, power quality, voltage regulation, and frequency regulation capabilities using NEC’s ESS to address these problems.
Enel Distribuzione is experimenting with cutting-edge distribution and auxiliary services with the help of NEC’s storage solution. The ESS will be utilised in particular to regulate the flow of energy between their network and the National Grid.
Enel Distribuzione estimates the volume of energy flow from their key substations to the national grid and provides the Transmission System Operator (TSO) with the data from the Energy Exchange Profile.
When fluctuations in renewable energy generation cause the gap between the Energy Exchange Profile and actual energy flow to surpass the threshold, NEC’s ESS works to reduce the gap by flexibly charging or discharging the batteries.
The smart grid infrastructure of Enel will eventually be integrated with NEC’s ESS to provide a two-way, real-time information exchange of electricity demand. This infrastructure is based on an automated metre management system with smart metres installed at homes, offices and factories, in addition to new innovative big data analytics and IT systems.
NEC has emerged as the top supplier of lithium-ion grid energy storage devices in the world according to its recently announced acquisition of A123 Energy Solutions.
NEC will further progress its Smart Energy business to build cutting-edge infrastructure solutions that contribute to a better society by integrating its market-leading ICT technology with A123 Energy Solutions’ system integration experience.
