Redelfi

What Redelfi does

Redelfi S.p.A. is an Italian industrial developer of sustainable energy infrastructure, listed on Euronext Growth Milan (ticker RDF.MI) since June 2022, with operational headquarters in Genoa and legal headquarters in Milan. The company specializes in the authorization, development, and sale of stand-alone Battery Energy Storage System (BESS) projects, with a current Italian pipeline of approximately 4.3 GW held through the parent (950 MW) and the 51%-owned subsidiary Bright Storage S.p.A. (3.3 GW, with Flash S.p.A./WRM Group holding 49%). In January 2026 Redelfi extended into Data Center development in Italy through a partnership with WRM Group, creating a second infrastructure vertical targeted at digital and AI-driven workloads.

Redelfi generates revenue primarily by developing BESS projects to a permitted, Ready-To-Build stage and then selling them to infrastructure investors, utilities, and battery operators, with a recent major supply partnership with Hyperstrong covering 4.6 GWh of capacity in Italy. The model is capital-light and project-based—employees number 1–10 and the FY2025 Production Value of €27M and EBITDA of €15.7M (58.3% margin) reflect transaction-driven economics rather than recurring services. Technology (cells, racks, power electronics) is procured from third-party suppliers, with AFRY providing technical and permitting support and Rothschild & Co / Mediobanca currently advising on the divestiture of the 3.3 GW Bright Storage pipeline.

The company is repositioning toward a pure-play Italian infrastructure focus: in February 2026 Redelfi announced it is evaluating the divestiture of its US subsidiaries (BESS Power Corporation and RAL Green Energy Corporation) on the basis that they do not contribute positively to Group EBITDA, and a spin-off of BESS Power Corporation was executed in November 2025. Governance is led by Chairman Davide Sommariva, with CEO Raffaele Palomba, CFO Emanuele Cardone, and an IR team headed by Erika Padoan; the largest shareholder is Marinetta s.s. (controlled by Sommariva) at approximately 38.75% of shares.

Product overview

Redelfi is an Industrial Group specializing in the development of innovative energy infrastructure, operating two core product lines: Battery Energy Storage Systems (BESS) and Data Centers. The BESS business, conducted through the parent company and its subsidiaries Bright Storage (51%-owned, focused on Italian pipeline up to 3.3 GW) and BESS Power Corporation (US subsidiary developing projects in Texas), enables energy storage and grid stabilization to accelerate the energy transition. The Data Center division, launched via a partnership with WRM Group, provides digital infrastructure in Italy. The company operates as a developer, focusing on the authorization and permitting process for these infrastructure projects rather than manufacturing or construction.
