The success of an auction for fast reserve grid services held by Italy’s transmission system operator (TSO) indicates a strong appetite for battery storage, but market rules and regulations need some revision to capture that opportunity. At a round table session today at the Energy Storage Summit 2021, the country’s storage market and its future prospects were discussed. Paolo Marino, director of Milan-headquartered energy markets consultancy REF-E, said that there is a pipeline of projects under development of more than 1GW in the country, with many stakeholders eager to be “part of the story” as Italy strives towards its renewable energy goals.
