US renewables developer Emeren Group has entered a co-development agreement with Arpinge to establish a 300MW battery energy storage system (BESS) portfolio in southern Italy.

The collaboration is expected to bolster Emeren's position in the Italian BESS market, where it has already secured 1.37GW within its permitting pipeline.

Arpinge Group CEO Federico Merola stated: “Collaborating with Emeren on this significant battery storage portfolio underscores our commitment to sustainable infrastructure investments that align with Italy's energy transition objectives.

“This partnership leverages our combined expertise to accelerate the development of critical energy storage solutions, enhancing grid stability and supporting the integration of renewable energy sources.”

The collaboration marks Emeren's fourth partnership with an Italian entity on environmentally sustainable investments.

It is aligned with Italy's ambition to transition towards cleaner energy sources, which is expected to expedite the permitting and development procedures.

Emeren Group CEO Yumin Liu stated: “This partnership with Arpinge marks a promising step forward in our strategic expansion within Italy's energy storage industry.

“Our success in securing partnerships with top-tier investors like Arpinge reflects Emeren's capability to capture market opportunities early and drive significant value through our proven development service agreement (DSA) model.

“With the support of our skilled Italian team, we look forward to delivering robust results as we advance toward a successful close to the year.”

In April 2024, Emeren Group signed a co-development agreement with Nuveen Infrastructure to create a battery storage portfolio in Italy.

Arpinge is a permanent capital vehicle formed by the Italian pension funds of Cassa Geometri, Eppi and Inarcassa. It invests in infrastructure and promotes greenfield projects.
