Volt ESG is the main shareholder of Fucino Green, a renewable energy investor in Italy.

Maria Laura Spagnolo, president and co-CEO of Lemon Sistemi, commented: “We are very pleased to announce the signing of this contract, which is fully in line with the initiatives dedicated to the capacity market and launches us into the great challenge of the energy transition.”

The capacity market alluded to is one that was run by Terna last year and saw over 1GW of BESS projects awarded contracts, kickstarting the market. did a deep-dive into the Italian market for a recent edition of Solar Media’s quarterly journal PV Tech Power.

This week, Matrix Renewables bought a 410MW/3,280MWh portfolio from development partner Emeren while Altea Green Power announced earlier this month it was in talks to sell a set of four projects totalling 1GW to two international investors.

Prior to these, GW-scale BESS development agreements were stuck by Redelfi and WRM, and Eku Energy and Renera, while Field, Aura Power and SUSI Partners are all entering the market too.’ publisher Solar Media will host the 9th annual Energy Storage Summit EU in London, 21-22 February 2024.
