Business Generation

    At December 31, 2008, we were the fourth largest power generation griup in Brazil as measured by total installed capacity. At December 31, 2008, we generated electricity at 58 hydroelectric plants, 04 thermoelectric plants and 01 wind farm and had a total installed generation capacity of 6,692 MW, of which hydroelectric plants accounted for 6,507 MW, thermoelectric plants accounted for 184 MW and our wind farm accounted for 1 MW.

    Business Transmission

    We are engaged in the electric power transmission business, which consists of transporting electric power from the facilities where it is generated to the distribution networks for delivery to end users. We transport energy produced at our own generation facilities as well as energy that we purchase from Itaipu, the interconnected power system and other concessionaires. Our transmission network is comprised of power transmission lines with a voltage capacity equal to or greater than 230 kV and is part of the national transmission grid regulated by the ONS. As of December 31, 2008, our transmission network in Minas Gerais consisted of 51 Kilometers of 525 kV, 2,787 Kilometers of 500 kV lines, 2,002 Kilometers of 345 kV lines and 915 Kilometers of 230 kV lines, as well as 38 substations with a total of 94 transformers and an aggregate transformation capacity of 15,583 MVA.

    Business Distribution

    We have an exclusive distribution concession in Minas Gerais that grants us exclusive rights to supply electric energy to consumers within our concession area except for consumers that may be eligible, in accordance with the legislation, to become free consumers (currently consumers with demand of higher or equal to 3 MW). As of December 31, 2008, we owned and operated 451,539 Kilometers of distribution lines, through which we supplied electricity to nearly 10 million customers. At December 31, 2008, we were the largest electricity distribution concessionaire in Brazil in terms of transported energy, number of consumers and network Kilometers.

    Other Businesses

    While our main business consists of the generation, transmission and distribution of electric power, we also engage in the business of distributing natural gas in Minas Gerais through our consolidated, majority-owned subsidiary Gasmig. We also engage in the telecommunications business through our consolidated subsidiary Infovias, a company created for the purpose of providing a fiber-optic and coaxial cable network installed along our transmission and distribution lines through which telecommunication services can be provided.
