Petrobras signs agreement to increase Brazilian energy supplies

(Rio de Janeiro, May 3, 2007). – PETRÓLEO BRASILEIRO S/A - PETROBRAS, [Bovespa: PETR3/PETR4, NYSE: PBR/PBRA, Latibex: XPBR/XPBRA, BCBA: APBR/APBRA], a Brazilian international energy company, announces that announces that it will sign a Pledge Agreement with the National Electricity Energy Agency (Aneel) to increase available generating capacity at 24 thermoelectric power plants to meet requiirements, including existing contractual commitments.

The terms of the Pledge Agreement are in line with the Company’s strategy of developing the Brazilian natural gas market, operating as an integrated energy company in order to assure returns on its portfolio of thermoelectric generation assets, the consolidation of which was concluded recently with the leasing of the Piratininga plant.

Petrobras’ commitments under the Agreement are a component part of the Company’s Business Plan for the 2007-2011 period. The Plan envisages total investments of approximately US$ 22.1 billion to supply about 70 million cubic meters/day of domestically produced gas by 2010, import of 20 million cubic meters of LNG (Liquefied Natural Gas) by 2009, in addition to maintaining natural gas imports of 30 million cubic meters/day provided under contract with Bolivia.

Implementation of the Agreement will add generating capacity of approximately 4GW by 2011 not only through greater supplies of natural gas but also through the conversion of plants to operate on a bi-fuel basis and the engagement of fuel-oil fired plants. Initially these initiatives will increase generation capacity, and, subsequently, endow Petrobras’ thermoelectric generation complex with greater operational flexibility and reliability.

Petrobras believes that these actions, allied to others, such as the formal contracting of forecast demand and an energy generation capacity reserve, will provide greater operational security to the domestic electricity supply system.
