What I4B - The Belgian Infrastructure Fund does

I4B - The Belgian Infrastructure Fund is a Belgian société anonyme incorporated on 22 February 2019, organized as an Alternative Investment Fund (AIF) under EU AIFMD regulations and Belgian AIFM Law, with its registered office in Brussels. The fund was launched with EUR 150 million of seed capital (EUR 50 million each) from three founding institutional investors — AG Insurance (Belgium's largest insurance company with EUR 70Bn+ AUM), SFPIM (the Belgian federal holding company / sovereign wealth fund), and Synatom (100% subsidiary of Engie Electrabel) — and targets a total fund size of EUR 250 million. External management is provided by Infra4Be Management SA, a FSMA-registered AIFM established in December 2018.

The fund invests across four infrastructure verticals in Belgium: Energy Transition (battery storage, solar, wind, hydrogen, heating networks), Digital Transition (data centers, fiber, telecom towers), Transport & Mobility (road, rail, bridges, locks, dams), and Social & Security (health, education, public welfare). It provides long-term equity or quasi-equity capital to projects at greenfield, yellowfield, and brownfield stages and can participate in public/private DBFM tender processes. Deployments include lead-equity participation in the EUR 1 billion+ R4WO Ghent ring road PPP (financial close May 2024), anchor investment in the Proximus fiber-to-the-premises consortium covering 1.7 million homes and businesses (June 2022), and a battery energy storage portfolio aggregating 620 MW / 2,140 MWh / EUR 600 million across four Belgian sites by June 2026 — anchored by the Visé BESS with Luminus (2025) and Project Volt with Weerts Group/Aukera Energy (2026, secured via Elia's Y-4 CRM auction).

The firm's revenue model is fund management: it earns management fees on committed/deployed capital and is positioned to earn carried interest on successful long-term infrastructure exits. Deal flow is generated via direct institutional relationships and public tender participation; capital is sourced privately from Belgian institutional investors (insurance, sovereign, pension). The fund operates with an 11–50 person team led by CEO André Autrand (former Global Head of infrastructure at Edmond de Rothschild), CIO Samuel de Lhoneux (former Head of infrastructure at AG Insurance), Chairman Jean-Edouard Carbonnelle (former CEO of Cofinimmo), and CFO Nadia Popova de Coninck.
