MILAN – ContourGlobal, the energy company backed by U.S. investment firm KKR, announced on Thursday, July 3, its acquisition of a portfolio of battery energy storage systems (BESS) in Italy. The newly acquired projects boast a combined power capacity of approximately 1.6 gigawatts (GW) with storage durations extending up to eight hours, marking a significant expansion of the company's European footprint in the rapidly evolving energy storage sector.

This strategic acquisition positions ContourGlobal directly for Italy's inaugural storage capacity auction, slated for September. The auction, managed by Italy's transmission system operator Terna Rete Elettrica Nazionale SpA, is designed to procure essential grid services and enhance the utilization of the country's burgeoning renewable energy generation. The substantial capacity and extended duration of ContourGlobal's new portfolio are critical attributes for participating effectively in such a competitive bidding process, where long-duration storage is increasingly valued for grid stability and peak shaving.

The move by ContourGlobal aligns with a broader trend across Europe, where battery storage capacity is projected to undergo a five-fold expansion by 2030. This rapid growth is driven by several factors, including the imperative to integrate higher penetrations of variable renewable energy, the declining costs of battery technology, and the increasing returns for energy majors, project developers, and traders. As renewable energy sources become the dominant form of generation, robust energy storage solutions are indispensable for maintaining grid reliability, managing supply-demand imbalances, and preventing costly curtailment of clean power.

Italy, in particular, is accelerating its energy transition, with ambitious targets for renewable energy deployment. The country's grid infrastructure requires significant upgrades and flexibility solutions to accommodate this shift. Large-scale battery storage, such as the projects acquired by ContourGlobal, provides the necessary agility to balance the grid, offer ancillary services, and optimize energy flows, thereby supporting Italy's national energy security and climate objectives. The investment by KKR, a global leader in private equity, through its portfolio company ContourGlobal, underscores the increasing confidence of institutional investors in the long-term growth prospects and profitability of the energy storage market.

Industry experts anticipate that the success of Italy's upcoming capacity auction will set a precedent for similar mechanisms across other European nations, further stimulating investment in grid-scale storage. ContourGlobal's proactive entry into this market segment with a substantial portfolio demonstrates a clear strategic vision to capitalize on the critical infrastructure needs of a decarbonizing energy system.
