The main benefits of storage are:

• the integration of more renewables (especially solar PV and wind) in the energy mix.
• storage will decrease the need to invest in new conventional generation capacity.
• storage improves energy security by optimising the supply and demand, thus reducing the need to import electricity via interconnectors.
• storage provides system stability during electricity outages by supplying energy at these times and reducing the financial costs of power outages.
• utilisation of storage also means fewer and cheaper electricity transmission and distribution system upgrades are required.
• energy can be stored when prices are low and used on site when they are high to save consumers and businesses money on their bills, the stored energy can be sold.
• storage can provide ancillary services to Grid System Operator TERNA at lower cost, lower carbon intensity than conventional thermal power plants.
