Green energy supplier Renergen has marked another significant milestone for Phase 2 of its Virginia gas project, through the completion of a notification process by the US International Development Finance Corporation (IDFC) to the US Congress of a commitment to provide a $500-million loan to Tetra4. Renergen earlier this month announced that it had received approval from the US IDFC for $500-million in senior debt funding, as well as secured a $250-million debt facility from Standard Bank. The funding was, however, dependent on the Congressional notification.
