Storage systems (BESS) have become a core infrastructure of the energy transition, as Affari e Finanza notes in Vito de Ceglia’s article.

They are no longer just an additional cost, but a genuine strategic infrastructure that bolsters grid security, stabilizes prices, and increases the bankability of renewable projects.

According to the latest analysis, the global BESS market – now at $13.7 billion – could surpass $43 billion by 2030, with annual demand rising to 620 GWh and an average growth rate above 21%. Forecasts also align with McKinsey, which projects a requirement of 450 to 620 GWh over the same period.

In Europe, storage is emerging as a major industrial infrastructure: by 2029, cumulative capacity could range between 66 and 183 GWh, driven mainly by utility-scale plants tied to electricity markets and grid services.

Italy is also entering a pivotal phase. Terna’s recent MACSE auction assigned 10 GWh of new storage capacity, supporting the national goal of 50 GWh installed by 2030. Our Country is now among the most appealing markets in Europe, thanks to a combination of favourable regulation, growth in renewables, and openness to private capital.

Strengthening this scenario are technological advances: lithium-iron-phosphate (LFP) batteries are improving cost, safety and durability, reducing project risk and reinforcing the industrial value of storage.

BESS are increasingly a crucial lever for integrating renewables, stabilizing the electricity system, and building a resilient and sustainable energy model.
