"GDF SUEZ announces the approval of commercial operation of the first generating unit of the Jirau project in Brazil

On 5 September, commercial operation of the first 75 MW turbine of the Jirau hydro power project has been officially approved by the Electricity Energy Regulatory Agency (ANEEL). Located on the Madeira River, in the State of Rondônia, the plant will have a total installed capacity of 3,750 MW and, when fully operational, will produce enough clean and renewable energy to meet the electricity demand of 10 million Brazilian households.
On May 17, the United Nations announced the registration of the Jirau project according to the Clean Development Mechanism (*). On the same date, GDF SUEZ published the official sustainability report developed by independent auditors based on the Hydropower Sustainability Assessment Protocol (**).
With the start of commercial operations, the generated electricity will effectively reduce the necessity of thermal generation and thus reduce increasing volumes of GHG emissions. Once completed, national GHG emissions will be reduced by 6 million tons per year.
(*) Project Design Document can be accessed from the UNFCCC website:

(20%). On May 13, GDF SUEZ and Mitsui announced a partnership where Mitsui will take a
20% equity interest in the project, expanding the long-term partnership between the two groups. The closing of the transaction is expected to occur during the second half of 2013,
upon satisfaction of certain conditions, including obtaining approvals from Brazilian
authorities (ANEEL- Electricity Energy Regulatory Agency) and lenders (BNDES and local commercial banks).
