Additional BNDES financing confirmed for Jirau hydro project, Brazil

GDF SUEZ is pleased to announce that BNDES (the Brazilian Development Bank) has confirmed an additional loan of up to BRL 2.3 billion (€0.9 billion) to the Jirau project in Brazil, potentially increasing the total project debt available to BRL 9.5 billion (€3.6 billion).

GDF SUEZ also announces the acquisition of an additional 9.9% equity holding from Camargo Correa in the Jirau hydro power plant. The price is based on Camargo's adjusted equity contributions in the project to date. This acquisition is subject to regulatory approval and is expected to be completed in Q4 2012.

Since the inception of the project, the shareholders had agreed that Camargo Correa would exit the Jirau HPP during the later stages of construction, once the principal construction risks had been addressed. Following the acquisition, GDF SUEZ will increase its stake in the Jirau project from 50.1% to 60%. Camargo Correa remains fully committed to the success of the project as the principal civil contractor.
