Announcement to the market

Cemig informs its stockholders and investors that, in a meeting held on 28 July 2004, the Supervisory Board was informed of the consolidated financial statements for the first half of 2004, which will be sent to the CVM on 4 August. The financial statements showed net profit of R$ 557 million, or R$ 3.44 per thousand shares. This compares with profit of R$ 535 million in the same period of 2003, representing an increase of 4%.

Sales revenue was R$ 3.395 billion. Cash flow as measured by Ebitda was R$ 1.141 billion, an increase of 60% from the second half of 2003.

Sales of electricity were 18,670 GWh, 4.5% more than in the first half of 2003, with sales to final consumers totaling 18,420 GWh, 3.7% more than in first half 2003.

Operational expenses were 20% higher, led by: purchases of natural gas for resale, which were up 86%; outsourced services, which increased 20%; and energy bought for resale, 4% higher than in the first half of 2003. Personnel expenses were 31% higher, primarily resulting from provisioning for expenses under the Voluntary Retirement Program, totaling R$ 24 million, which will make possible the reduction of approximately 1,000 in the company's number of employees.

The financial result, which was impacted by payment of R$ 200 million in Interest on Equity, also made a significant contribution.

Cemig will hold a meeting with the domestic and international investor markets on 5 August, announcing further details and making comments.
