AES Tiete Recorded Net Income of R$ 134.1 Million in 2Q08, Which Will Be Fully
Distributed as Dividends

SAO PAULO, Brazil, Aug. 13 /PRNewswire-FirstCall/ -- AES Tiete S.A.
(Bovespa: GETI3 and GETI4; OTC: AESAY and AESYY) today announced its results
for the 2nd quarter, 2008.
Comments by Mr. Alexandre Innecco - Finance and Investor Relations Officer
AES Tiete registered an EBITDA of R$ 288.9 million, 24.2% higher than in the
second quarter of 2007, while the net income of R$ 134.1 million represents a
5.6% reduction in comparison to the same period of last year.
The increase in the IGP-M, index used to adjust the Company's financial
debt, negatively impacted the net financial result and, consequently, its net
income. As of July, the same index has been applied annually, to set new
prices for the sale of electric energy as established in bilateral contracts
with Eletropaulo. Therefore, as of the third quarter, the negative impact of
the IGP-M over financial expenses will be neutralized by the results of higher
electric energy prices on AES Tiete's revenues.
The distribution of 100% of the quarterly earnings (R$ 134.1 million) as
dividends was approved by the Board of Directors on August 13, 2008,
reinforcing the dividend policy in effect since 2006.
