Airengy has received approval from Italy’s national transmission system operator TERNA to connect its lithium-ion battery energy storage system (BESS) to the Italian transmission grid in the Brindisi region. The confirmed connection point is the Pignicelle substation, located less than 3 km from the project site.

The facility will provide up to 3 gigawatt-hours (GWh) of storage capacity and inject up to 509.25 MW into the grid for several hours. By doing so, it will support voltage and frequency stability, facilitate peak load management, and enable greater penetration of variable renewable energy such as solar and wind into the transmission network. Construction is expected to take 20 months from signing the connection agreement.

The connection approval allows Airengy to advance engineering design, grid integration studies, and regulatory submissions to Italy’s Ministry of the Environment and Energy Security (MASE). This step is critical for ensuring optimal BESS sizing, control system integration, and compliance with Italian grid codes.

Yiftach Ron-Tal, Chairman of Airengy, highlighted that the project represents a major milestone in the company’s European energy storage strategy, which includes long-duration storage technologies like compressed air energy storage (CAPP). The project will contribute to system reliability, ancillary services provision, and dynamic grid support, demonstrating the technical value of large-scale BESS in modern power systems.

In parallel, Airengy is acquiring a portfolio of six solar projects in Poland (34 MW), which will be enhanced with BESS integration, illustrating the company’s approach to hybrid renewable + storage solutions for stable grid operation.
